Influence of patient sex and gender on medication use, adherence, and prescribing alignment with guidelines

Determinants of medication adherence in patients with acute coronary syndrome: a secondary analysis of a randomised clinical trial

BACKGROUND

Coronary heart disease (CHD) remains a leading cause of mortality and disability worldwide. Approximately half of the patients who have had a prior hospital admission for CHD will have a recurrent coronary event, with the majority of these occurring within 12 months. Despite well-established evidence-based therapies, medication non-adherence is highly prevalent and reasons for medication non-adherence are poorly understood. This study evaluates factors influencing adherence to secondary prevention medications in people with acute coronary syndrome (ACS).

METHODS

We performed a secondary analysis of TEXT messages to improve MEDication adherence and Secondary prevention after ACS (TEXTMEDS), a single-blind randomised clinical trial of 1424 patients with ACS from 18 hospitals across Australia. The primary outcome was self-reported medication adherence to each of up to five classes of guideline-recommended cardioprotective medications indicated for secondary prevention after ACS. Patients were followed up at 6-month and 12-month time points and were defined as adherent if at both time points, the proportion of indicated medications taken was >80% (>24/30 days in the preceding 1 month) for all five classes if not otherwise contraindicated. Logistic regression analysis and the Least Absolute Shrinkage and Selection Operator regularisation technique were used to assess the effect of sociodemographic and clinical factors on medication adherence.

RESULTS

The analyses included 1379 participants with complete adherence data (mean age 58.5±10.7 years; 1095 (79.4%) men). The following variables were associated with adherence to cardiovascular medications at both 6 and 12 months: greater number of total medications taken (OR: 1.33; 95% CI: 1.25 to 1.42) and attending a cardiac rehabilitation programme (1.47; 95% CI: 1.17 to 1.86). In contrast, female sex (0.67; 95% CI: 0.50 to 0.90) and physical disability (0.43; 95% CI: 0.23 to 0.77) were associated with lower likelihood of medication adherence.

CONCLUSIONS

Sociodemographic and clinical factors may influence medication adherence. Greater awareness, discussion and monitoring of these factors during patient follow-up may help improve medication adherence.

Sex and age effects on prevalence of CYP2C19 and CYP2D6 Phenoconversion risk over time in patients with psychosis

Pharmacogenetics in psychiatry may have benefits for medication treatment success. However, medication regimes leading to drug-drug interactions and potential phenoconversion of actionable pharmacogenetic phenotypes challenge the application of pharmacogenetics. Although polypharmacy is common, its impact in patients with psychosis is understudied, even though these patients might benefit from pharmacogenetics-guided medication adjustment. Here, we investigated the impact of two pharmacogenes relevant in psychiatric practice, CYP2C19 and CYP2D6, and the effect of sex and age. Medication use and predicted occurrence of phenoconversion was examined in a sample of patients with psychosis over a period of approximately six years. Bayesian statistics were applied to examine longitudinal effects. Our results show that women used more medications, including CYP2C19 and CYP2D6 inhibitors and (actionable) substrates. No significant sex or age differences were found for phenoconversion of either enzyme. A sex-effect on CYP2C19 inhibitor use was found but appeared to be driven by weakly inhibiting oral contraceptives, which were reported only in women. The phenoconversion rate for both enzymes appeared to change over time, suggesting that phenoconversion is a dynamic state that may affect patients differently over their lifetime. To further improve treatment in this patient population, long-term and regular updated medication monitoring in (pharmacogenetic) research as well as application in practice are recommended.

Sex and Gender in Myeloid and Lymphoblastic Leukemias and Multiple Myeloma: From Molecular Mechanisms to Clinical Outcomes

Biological sex and gender factors significantly influence the pathogenesis, progression, and treatment response in hematologic malignancies. This comprehensive review examines sex-specific differences in acute myeloid leukemia, acute lymphoblastic leukemia, chronic myeloid leukemia, and multiple myeloma through systematic analysis of the peer-reviewed literature published between 2014-2024 and identified through structured searches of PubMed, Web of Science, and MEDLINE databases. Epidemiological data demonstrate higher disease incidence (57% male vs. 43% female in MM, 63% male vs. 37% female in AML hospitalizations for ages 18-39) and inferior outcomes in male patients across malignancy types (5-year relative survival rates of 48.8% vs. 60.4% in females with AML), while female patients exhibit superior survival despite experiencing greater treatment-related toxicities. Our analysis reveals consistent sex-specific patterns in molecular mechanisms, including distinct mutational profiles, differences in immune system function, and sex-based pharmacokinetic variations that collectively suggest the necessity for sex-differentiated treatment approaches. The review identifies reproducible patterns across diseases, particularly in cytogenetic and molecular characteristics, with females demonstrating favorable prognostic mutations in leukemias and higher rates of chromosomal abnormalities in multiple myeloma. Despite these identifiable patterns, significant knowledge gaps persist regarding the underlying mechanisms of sex-based outcome differences. Incorporating sex and gender considerations into precision medicine frameworks represents a critical advancement toward optimizing treatment strategies and improving clinical outcomes for patients with hematologic malignancies.

Evaluating Treatment Patterns in Bell's Palsy Using Nationwide Employer-Sponsored Healthcare Claims

OBJECTIVE

Professional society guidelines provide clear recommendations regarding the use of high-dose steroids and/or antiviral therapy for Bell's palsy patients. This study evaluates national trends in the care of Bell's palsy patients and identifies current treatments.

METHODS

A retrospective cohort study of adult Bell's palsy patients was conducted using ICD-9-CM and ICD-10-CM diagnosis codes from 2013 to 2020. These patients were continuously enrolled in the employer-sponsored MarketScan commercial or Medicare outpatient and prescription drug claims data for at least 1 year. The main outcome of interest was prescription rates of high-dose steroids and antivirals after the diagnosis date.

RESULTS

In this cohort of 66,708 adult Bell's palsy patients, 29,824 (44.7%) received no treatment. 22,736 (34.1%) received combination therapy, 11,866 (17.8%) received steroids only, and 2282 (3.4%) received antivirals only. Males were more likely to receive combination therapy. 51.9% of Bell's palsy patients in this cohort received the AAO-recommended treatment of steroids within 72 h of diagnosis. Patients in the Southern and Western United States were more commonly prescribed combination therapy. Comorbidities such as cerebrovascular disease and symptoms like ear pain were associated with a higher likelihood of receiving combination therapy. Treatment initiation, particularly for steroids, occurred on the index date, first insurance claim, in 94.56% of cases.

CONCLUSION

Only 51.9% of Bell's palsy patients in this cohort received the AAO-recommended treatment with high-dose steroids with or without antiviral therapy. This research provides valuable insights into the real-world management of Bell's palsy, emphasizing the need for adherence to established treatment guidelines.

Effects of the Part D Senior Savings Model on racial and ethnic disparities in healthcare costs

OBJECTIVE

The Centers for Medicare & Medicaid Services tested the Part D Senior Savings Model ("PDSS Model") in 2021, capping monthly out-of-pocket (OOP) insulin costs at $35. Diabetes disproportionately affects racial/ethnic minorities compared to their non-Hispanic White (White) counterparts, so this study compared the changes in racial/ethnic disparities in healthcare costs among insulin users between Medicare and non-Medicare populations in 2021.

METHODS

This study analyzed the Medical Expenditure Panel Survey (2020-2021). The intervention group comprised Medicare beneficiaries aged ≥65, while the comparison group included a near-elderly non-Medicare population. The study outcomes included annual OOP/total costs in 2021 dollars for insulin, medication, health services (medical), and overall healthcare. A difference-in-differences-in-differences approach was employed to assess the PDSS Model's effects between White and each racial/ethnic minority group.

RESULTS

The weighted sample included 1,056,386 insulin users (53.89% intervention). In 2020, among the intervention group, non-Hispanic Black (Black) and Hispanic had similar or higher insulin costs than White patients. Black-White differences in OOP insulin costs were lowered more among the intervention group (cost ratio [CR] = 0.12, 95% confidence interval = 0.06-0.22) than the comparison group. Black-White differences in OOP costs for medication, health services, and overall healthcare widened more among the intervention group by 61-64%. These patterns were not seen for other racial/ethnic disparities.

CONCLUSIONS

Among insulin users, Black may have benefited more from the PDSS Model than White patients, which may be associated with enhanced insulin access and lower needs for other healthcare. Future studies should examine the long-term and heterogeneous impact of the PDSS Model.

Sex Differences in Prescription Patterns and Medication Adherence to Guideline-Directed Medical Therapy Among Patients With Ischemic Stroke

BACKGROUND

Ischemic stroke is a leading cause of death and disability. Society guidelines recommend pharmacotherapies for secondary stroke prevention. However, the role of sex differences in prescription and adherence to guideline-directed medical therapies (GDMT) after ischemic stroke remains understudied. The aim of this study was to examine sex differences in prescription patterns and adherence to GDMT at 1 year after ischemic stroke in a cohort of commercially insured patients.

METHODS

Using the Truven Health MarketScan database from 2016 to 2020, we identified patients admitted with ischemic stroke. GDMT was defined as any statin, antihypertensive agents, or oral anticoagulant prescription within 30 days after discharge. Medication adherence was estimated using the proportion of days covered at 1 year. The proportion of days covered <0.80 was used to define nonadherence. A multivariable model adjusting for covariates was performed to identify the factors associated with nonadherence at 1 year. This analysis was restricted to new users of GDMT.

RESULTS

Among 155 220 patients admitted with acute ischemic stroke during the study period, 15 919 met the inclusion criteria. The mean age was 55.7 years, and 8218 (51.7%) were women. Women were less likely to be prescribed statins (58.0% versus 71.8%) and antihypertensive agents (27.7% versus 41.8%). In this subset of patients with atrial flutter/fibrillation, women were also less likely to be prescribed oral anticoagulants (41.2% versus 45.0%). Women were more likely to be nonadherent (ie, proportion of days covered <0.80) to statins (47.3% versus 41.6%; P<0.0001), antihypertensives (33.3% versus 32.2%; P=0.005), and the combination of both (49.6% versus 45.0%; P=0.003). On multivariable analysis, women were likely to be nonadherent to statins and antihypertensive agents at 1 year (odds ratio, 1.23 [95% CI, 1.08-1.41]).

CONCLUSIONS

In this real-world analysis of commercially insured patients with ischemic stroke, women were less likely initiated on GDMT within 30 days after discharge. Women were more likely to be nonadherent to statins and antihypertensive agents at 1 year. Future efforts and novel interventions are needed to understand the reasons and minimize these disparities.

Concomitant use of clopidogrel and proton pump inhibitors: A retrospective analysis of prescription behaviour

AIMS

Since omeprazole and esomeprazole reduce the effect of clopidogrel on the inhibition of platelet aggregation, concomitant use of these drugs has been discouraged by the Food and Drug Administration (FDA) and European Medicines Agency (EMA) since 2010. Currently, it is unknown how often this undesired drug-drug combination is prescribed. The aim of this article is to determine the proportion of patients using omeprazole or esomeprazole among patients using clopidogrel with gastroprotective drugs and to identify differences between these two groups with regard to patient characteristics and prescriber characteristics.

METHODS

This was a retrospective analysis of Dutch outpatient medication prescription records between 2015 and 2022. The database had a coverage of approximately 62% of all outpatient prescriptions dispensed in The Netherlands.

RESULTS

The proportion of patients using omeprazole or esomeprazole as gastroprotective drug in combination with clopidogrel declined from 19.7% to 8.7% between 2015 and 2022. The undesired drug-drug combination was more often prescribed by internists, to women and to patients with polypharmacy (using >10 drugs).

CONCLUSIONS

Although the proportion of patients using clopidogrel together with omeprazole or esomeprazole declined between 2015 and 2022, the undesired combination is still frequently prescribed in The Netherlands. Education about this drug-drug interaction for pharmacists and prescribers is needed since pharmacotherapeutic alternatives are available.

Assessing Prevalence of Nonmedically Used Prescription Drug Involvement in Overdose Deaths Through Linkage of State Unintentional Drug Overdose Reporting System and Controlled Substances Monitoring Program Data

BACKGROUND

While illicit substances are commonly involved in the overdose crisis, prescription substances still play a role. Oftentimes, decedents do not have prescriptions for these substances at the time of death. As such, we sought to examine the prevalence of nonmedical drug use in Tennessee through linkage of fatal drug overdose and prescription data.

METHODS

We used State Unintentional Drug Overdose Reporting System (SUDORS) data to identify fatal drug overdoses in Tennessee from 2019 to 2022. Deaths were linked to Controlled Substances Monitoring Program data deterministically using name and date of birth. Nonmedical use was defined as a decedent having a prescription substance on toxicology but not having an active prescription for that substance at the time of death. Descriptive statistics were performed to assess prevalence overall and examine differences between drug classes.

RESULTS

We identified 7,281 SUDORS deaths from January 2019-2022 with complete toxicology that were able to be linked to prescription data. The median age of decedents was 40 years with 34.2% female and 65.8% males. Prevalence of nonmedical use differed for each category, 1,263(17.3%) for nonmedical opioid use, 1,216(16.7%) for nonmedical benzodiazepine use, 436 (6.0%) for nonmedical gabapentin use, and 152 (2.1%) for nonmedical stimulant use. Overtime, nonmedical use of opioids, benzodiazepines, and stimulants has decreased.

CONCLUSION

Through linkage of fatal overdose and prescription data, we found the prevalence of nonmedical use to be 33% in Tennessee. Increasing education on the dangers of nonmedical use, the importance of safe drug disposal, storage, and only using medications as prescribed is encouraged to reduce improper use as the drug landscape continues to shift.

Gender differences in the association between adherence to healthy diet principles and adherence to cardiopreventive medication among adults from Québec (Canada)

Adherence to healthy diet principles and to cardiopreventive medication, both key behaviours in CVD prevention, is known to differ between women and men. Whether these adherence behaviours are differentially related among women and men has never been thoroughly assessed. The objective was to assess gender differences in the association between adherence to healthy diet principles and to cardiopreventive medication in adults free of CVD. This cross-sectional study included 268 women and 204 men from the CARTaGENE cohort (Québec, Canada) who were using antihypertensive and/or cholesterol-lowering medication. Adherence to healthy diet principles was assessed using the Alternate Healthy Eating Index (AHEI, %), calculated from a validated FFQ assessing diet in the 12-month preceding its completion. Medication adherence was assessed using the daily pharmacotherapy possession rate (DPPR, %), calculated from prescription claim data over the same 12-month period. In multivariable-adjusted analyses, an inverse association between AHEI and DPPR was observed among men (βAHEI for 10 % increment in DPPR = -0·65 %; 95 % CI -1·28 %, -0·03 %; P = 0·04), while it tended to be positive among women (β = 0·44 %; 95 % CI -0·11 %, 1·00 %; P = 0·12; Pgender×DPPR = 0·01). The negative association between AHEI and DPPR was stronger among men who never smoked or used cholesterol-lowering medication only. Among women, the positive association was stronger and statistically significant among those with obesity or using ≥ 3 medications simultaneously. Association between adherence to healthy diet principles and to cardiopreventive medication differs between women and men, with men potentially facing greater challenges in achieving optimal complementarity between these two behaviours.

Imatinib adherence prediction using machine learning approach in patients with gastrointestinal stromal tumor

BACKGROUND

Nonadherence to imatinib is common in patients with gastrointestinal stromal tumor (GIST), which is associated with poor prognosis and financial burden. The primary aim of this study was to investigate the adherence rate in patients with GIST and subsequently develop a model based on machine learning (ML) and deep learning (DL) techniques to identify the associated factors and predict the risk of imatinib nonadherence.

METHODS

All eligible patients completed four sections of questionnaires. After the data set was preprocessed, statistically significance variables were identified and further processed to modeling. Six ML and four DL algorithms were applied for modeling, including eXtreme gradient boosting, light gradient boosting machine (LGBM), categorical boosting, random forest, support vector machine, artificial neural network, multilayer perceptron, NaiveBayes, TabNet, and Wide&Deep. The optimal ML model was used to identify potential factors for predicting adherence.

RESULTS

A total of 397 GIST patients were recruited. Nonadherence was observed in 185 patients (53.4%). LGBM exhibited superior performance, achieving a mean f1_score of 0.65 and standard deviation of 0.12. The predominant indicators for nonadherent prediction of imatinib were cognitive functioning, whether to perform therapeutic drug monitoring (if_TDM), global health status score, social support, and gender.

CONCLUSIONS

This study represents the first real-world investigation using ML techniques to predict risk factors associated with imatinib nonadherence in patients with GIST. By highlighting the potential factors and identifying high-risk patients, the multidisciplinary medical team can devise targeted strategies to effectively address the daily challenges of treatment adherence.

Exploring Sex, Gender, and Gender-Related Sociocultural Factors in Clinical Decision-Making for Older Adults Using a Prescribing Cascade Vignette: A Transnational Qualitative Study

BACKGROUND

Despite growing awareness of sex differences in inappropriate prescribing among older adults, including the initiation of problematic prescribing cascades, the impact of gender bias remains largely unexplored.

OBJECTIVES

We explored how a patient's sex and gender-related sociocultural factors influence physicians' prescribing decisions, potentially leading to prescribing cascades in older adults. A secondary objective was to explore whether and how physician sex affected prescribing decisions for female and male patients.

METHODS

Physicians in Canada and Italy were presented with a clinical vignette describing an older male or female patient on amlodipine presenting with peripheral edema. Physicians were interviewed using the 'think-aloud' method to describe their treatment considerations. Thematic multi-site analysis was used to analyze the data.

RESULTS

Of 30 physicians, only two considered prescribing a diuretic for an older female patient. Most physicians identified amlodipine as the cause of the edema and adjusted or substituted the medication, often making these treatment decisions without considering sex- and gender-related sociocultural factors. When prompted, physicians acknowledged the relevance of these factors, but their responses varied. Some adapted their treatment plans, noting the challenges of managing edema, particularly for female patients, whereas others did not incorporate these considerations. Interestingly, some physicians adjusted their plans based on gender-related factors yet still stated that gender did not influence their treatment decisions. No variations in treatment decisions based on physician sex were observed.

CONCLUSION

The study reveals a gap between physicians' recognition of gender-related sociocultural factors and their consistent integration into clinical decision-making, highlighting the need for more nuanced approaches in prescribing practices.

Mortality trends from all causes and diabetes mellitus according to sex between 1998 and 2021

Introduction

The variation of mortality rates according to sex, regarding mortality from all causes and from specific conditions related to diabtes mellitus (DM) is widely discussed.

Aim

The aim of this study was to analyze the mortality trends from all causes and DM according to sex in Bauru, São Paulo, Brazil, between 1998 and 2021.

Methodology

This was a retrospective, observational, epidemiological, population-based study. Data were collected from the Unified Health System, the Brazilian Institute of Geography and Statistics, and the Automatic Recovery System. A time series analysis was conducted using age-adjusted rates for segmented analysis with annual percentage change and average annual percentage change (AAPC) computed.

Results

All-cause mortality rose from 2.080 to 3.806 deaths, an 82.31% increase, with a stable trend (AAPC: −0.70%). DM-related deaths increased from 84 to 168, with a stable trend (AAPC: −0.90%). Sex-specific mortality figures show a higher average mortality rate in males for all causes (26.50% higher) and females for DM (25% higher). All-cause mortality had a stationary trend for both sexes. DM mortality showed a slight decline in females (AAPC: −1.30%) but remained stable in males.

Conclusions

Men maintained a higher mortality rate from all causes when compared to women. Women kept a higher DM-related mortality rate than men, although their DM-related mortality rate showed a decreasing trend throughout the period evaluated.

Gender Disparities in Advanced Lung Diseases: do They Persist Towards the End of Life?

BACKGROUND

Advanced lung diseases are prevalent in women, yet are underrecognized and under-treated due to differing epidemiology and pathophysiology.

AIM

To investigate any gender differences in access to palliative care and end-of-life management for patients with advanced lung diseases.

METHODS

A post-hoc analysis was conducted using three datasets that included information regarding the provision of palliative care to patients with advanced lung diseases - chronic obstructive pulmonary disease (COPD), fibrotic interstitial lung diseases (f-ILD) or non-small cell lung cancer (NSCLC) in tertiary and regional hospitals in Victoria, Australia, from 2004 to 2019.

RESULTS

343 patients with advanced COPD, 67 with f-ILD and 1022 with NSCLC were included. Compared to men, women with COPD (n = 126, 36.7%) were less likely to have smoked (P = 0.024), had significantly worse lung function (P < 0.001), and were more likely to receive non-invasive ventilation at end of life (P = 0.021). Women with fibrotic ILDs (n = 30, 44.8%) had significantly worse lung function (P < 0.001) and were more likely to experience exacerbations during their last two years of life (P < 0.001). Women with NSCLC (n = 457, 44.7%) were significantly younger (P< 0.001), less likely to have smoked (P < 0.001) or had asbestos exposure (P < 0.001). There were no significant differences between men and women with advanced lung diseases regarding referral to palliative care services (P = 0.369), hospital place of death (P = 0.915), or end-of-life management.

CONCLUSIONS

Despite differences in lung function, exacerbations and targeted therapies, men and women with advanced lung diseases received equal access to symptom palliation and palliative care services towards the end of life.

Antihypertensive Medication Adherence and Medical Costs, Health Care Use, and Labor Productivity Among People With Hypertension

BACKGROUND

Hypertension affects nearly half of US adults yet remains inadequately controlled in over three-quarters of these cases. This study aimed to assess the association between adherence to antihypertensive medications and total medical costs, health care use, and productivity-related outcomes.

METHODS AND RESULTS

We conducted cross-sectional analyses using MarketScan databases, which included individuals aged 18 to 64 years with noncapitated health insurance plans in 2019. Adherence was defined as ≥80% medication possession ratio for prescribed antihypertensive medications. We used a generalized linear model to estimate total medical costs, a negative binomial model to estimate health care use (emergency department visits and inpatient admissions), an exponential hurdle model to estimate productivity-related outcomes (number of sick absences, short-term disability, long-term disability), and a 2-part model to estimate productivity-related costs in 2019 US dollars. All models were adjusted for age, sex, urbanicity, census region, and comorbidities. We reported average marginal effects for outcomes related to antihypertensive medication adherence. Among 379 503 individuals with hypertension in 2019, 54.4% adhered to antihypertensives. Per person, antihypertensive medication adherence was associated with $1441 lower total medical costs, $11 lower sick absence costs, $291 lower short-term disability costs, and $69 lower long-term disability costs. Per 1000 individuals, medication adherence was associated with lower health care use, including 200 fewer emergency department visits and 90 fewer inpatient admissions, and productivity-related outcomes, including 20 fewer sick absence days and 442 fewer short-term disability days.

CONCLUSIONS

Adherence to antihypertensives was consistently associated with lower total medical costs, reduced health care use, and improved productivity-related outcomes.

Assessing the level of device-measured physical activity according to insomnia symptoms in 1,354 individuals with diabetes: the HUNT Study, Norway

Background

Insomnia symptoms that influence daytime functioning are common among adults with type 2 diabetes. However, no previous study has examined if levels of physical activity differ among adults with diabetes with and without insomnia symptoms. Thus, the aim of this study was to assess the difference in total physical activity (TPA) and moderate-to-vigorous physical activity (MVPA) levels in individuals with diabetes with and without insomnia symptoms.

Methods

This cross-sectional study included 1,354 participants with any type of diabetes who participated in the Norwegian HUNT4 Study, 2017-19. Participants were defined to have 'insomnia symptoms' if they reported difficulty initiating and/or maintaining sleep ≥ 3 nights/week during the last 3 months. MVPA (defined as moderate/brisk walking [> 4.0 km/h], running, and cycling), and TPA (MVPA including slow walking [≤ 4.0 km/h]) were determined from two accelerometers worn on the thigh and lower back. Analyses were stratified by age and sex.

Results

The median age was 67 years and 491 (36%) had insomnia symptoms and 37 (3%) had insomnia disorder. Among women, 28% with one or more insomnia symptoms fulfilled the recommended minimum level of physical activity, as compared to 34% in women without insomnia symptoms. The corresponding proportions in men were 48% and 45%. Women above 65 years with insomnia symptoms performed less TPA (-73 min/week, 95% CI -122 to -24) and MVPA (-33 min/week, 95% CI -50 to -15), compared to women without insomnia symptoms in the same age group. There was no clear difference in physical activity levels according to insomnia symptoms in men or women below 65 years. Women and men with insomnia disorder had substantially lower TPA (women: -192 min/week, 95% CI -278 to -106; men: -276 min/week, 95% CI -369 to -193) and MVPA (women: -37 min/week, 95% CI -63 to -11; men: -67 min/week, 95% CI -83 to -50) than those without insomnia symptoms.

Conclusions

This study showed that women above 65 years with insomnia symptoms and individuals with insomnia disorder performed less physical activity, suggesting that these subgroups may suffer from additional challenges that prevent them from engaging in regular physical activity.

Sex differences in unmet needs between male and female older Veterans

Aging Veterans face complex needs across multiple domains. However, the needs of older female Veterans and the degree to which unmet needs differ by sex are unknown. We analyzed responses to the HERO CARE survey from 7,955 Veterans aged 55 years and older (weighted N = 490,148), 93.9% males and 6.1% females. We evaluated needs and unmet needs across the following domains: activities of daily living (ADLs), instrumental ADLs (IADLs), health management, and social. We calculated weighted estimates and compared sex differences using age-adjusted prevalence ratios. On average, female Veterans were younger, more were Non-Hispanic Black and unmarried. Females and males reported a similar prevalence of problems across all domains. However, compared to males, female Veterans had a lesser prevalence of missed appointments due to transportation (aPR 0.49; 95% CI: 0.26-0.92), housework unmet needs (aPR: 0.44; 95% CI: 0.20-0.97), and medication management unmet needs (aPR: 0.33; 95% CI: 0.11-0.95) but a higher prevalence of healthcare communication unmet needs (aPR: 2.40; 95% CI: 1.13-5.05) and monitoring health conditions unmet needs (aPR: 2.13, 95% CI: 1.08-4.20). Female Veterans' common experience of unmet needs in communicating with their healthcare teams could result in care that is less aligned with their preferences or needs. As the number of older female Veterans grows, these data and additional work to understand sex-specific unmet needs and ways to address them are essential to providing high-quality care for female Veterans.

Sex-specific social, lifestyle, and physical health risk factors in cataracts development

BACKGROUND

Cataract is a leading cause of blindness worldwide. However, little is known about sex differences in cataracts. Our study aimed to explore potential sex differences in the relationships between key social, lifestyle, and physical health risk factors and the incidence of cataracts.

METHODS

A total of 117,972 participants from the UK Biobank were included in this prospective cohort study. Cox proportional hazard models were used to calculate hazard ratios (HRs) and female-to-male ratios of HRs (RHRs) with 95% confidence intervals (CIs) for cataract risk factors. Poisson regression was used to assess the incidence of cataracts (per 10,000 person-years).

RESULTS

A total of 117,972 individuals without preexisting eye diseases were enroled in the analysis. 4172 subjects (54.8% female) were diagnosed with cataracts during follow-up. The crude incidence rates per 10,000 person-years were 35.06 for females and 29.15 for males. The incidence of cataracts increased in both males and females with factors such as Asian or Black ethnicity, smoking status, obesity, diabetes, and myopia. However, males who consumed alcohol or were unemployed suffered a greater risk of cataracts compared to their female counterparts, while high socioeconomic status, elevated blood pressure and metabolic syndrome were associated with a greater risk of cataracts in females than in males.

CONCLUSION

This study provides a comprehensive overview of sex differences in the associations between cataracts and various risk factors. Our findings highlight that socioeconomic and lifestyle risk factors are more strongly linked to cataract risk in males, whereas females with systemic diseases face a greater risk of developing cataract.

Differential effects of environmental exposures on clinically relevant endophenotypes between sexes

Sex and gender differences play a crucial role in health and disease outcomes. This study used data from the National Health and Nutrition Examination Survey to explore how environmental exposures affect health-related traits differently in males and females. We utilized a sex-stratified phenomic environment-wide association study (PheEWAS), which allowed the identification of associations across a wide range of phenotypes and environmental exposures. We examined associations between 272 environmental exposures, including smoking-related exposures such as cotinine levels and smoking habits, and 58 clinically relevant blood phenotypes, such as serum albumin and homocysteine levels. Our analysis identified 119 sex-specific associations. For example, smoking-related exposures had a stronger impact on increasing homocysteine, hemoglobin, and hematocrit levels in females while reducing serum albumin and bilirubin levels and increasing c-reactive protein levels more significantly in males. These findings suggest mechanisms by which smoking exposure may pose higher cardiovascular risks and greater induced hypoxia for women, and greater inflammatory and immune responses in men. The results highlight the importance of considering sex differences in biomedical research. Understanding these differences can help develop more personalized and effective health interventions and improve clinical outcomes for both men and women.

Sex-difference of multifactorial intervention on cardiovascular and mortality risk in DKD: post-hoc analysis of a randomised clinical trial

OBJECTIVE

Women with type 2 diabetes experience higher cardiovascular and mortality risk than men possibly because of a sub-optimal cardio-protective treatment. We evaluated whether an intensive multifactorial therapy (MT) produces similar protective effect on development of adverse outcomes in women and men.

RESEARCH DESIGN AND METHODS

Nephropathy in Diabetes type 2 study is an open-label cluster randomized trial comparing the effect of Usual Care (UC) or MT of main cardiovascular risk factors (blood pressure < 130/80 mmHg, HbA1c < 7%, LDL < 100 mg/dL, and total cholesterol < 175 mg/dL) on cardiovascular and mortality risk in patients with type 2 diabetes. In this post-hoc analysis, we stratified patients by sex to compare the occurrence of MACEs (primary endpoint) and all-cause death (secondary endpoint) between women (104 MT and 105 UC) and men (103 MT and 83 UC).

RESULTS

Achievement of therapeutic goals was similar by sex, with 44% and 47% of women and men in MT achieving at least 3 targets vs. 16% and 20% of women and men in UC. During a median follow-up of 13.0 years, we recorded 262 MACE (48.5% in women) and 189 deaths (53.6% in women). Compared to the UC group, the risk of MACE in the MT group was reduced by 52% in women and by 44% in men (P = 0.11). Conversely, the reduction in mortality risk by MT was greater in women (44% versus 12%, P = 0.019).

CONCLUSIONS

MT similarly reduces the risk of MACEs in either sex. This therapeutic approach is associated with a survival advantage in women as compared with men and it may represent an important rationale to motivate physicians in overcoming their therapeutic inertia often encountered in female patients as well as to encourage patients of both sexes at improving their adherence to multidrug therapy.

Evaluating patient-reported adherence and outcomes in specialty disease states: A dual-site initiative

BACKGROUND

Patient-reported outcomes (PROs) are often used by clinicians to evaluate patient response to specialty medications used to treat multiple sclerosis (MS) and rheumatologic conditions. Identifying associations among PROs and patient characteristics could inform patient-centered treatment monitoring.

OBJECTIVE

To examine the association among patient characteristics and PROs, including patient-reported adherence (defined as no missed doses), medication tolerance, patient perceived effectiveness, and health care resource utilization (HCRU; defined as emergency department visits or hospitalizations), for patients prescribed specialty medications in 2 health system specialty pharmacies.

METHODS

A dual-center, retrospective review of monthly medication assessments completed by Vanderbilt Specialty Pharmacy and University of Illinois Hospital and Health Sciences System specialty pharmacy was conducted. Patients were included if they received at least 3 fills of a specialty medication from rheumatology or MS clinics from October 2019 to March 2022, excluding patients with more than a 30-day supply. Primary outcomes were the PROs of patient-reported adherence, medication tolerability, perceived effectiveness, and HCRU. For each of the 2 primary outcomes (adherence and tolerability), a mixed-effects logistic regression model was used to test for associations with age, sex, race, clinic, site, and the other PROs.

RESULTS

A total of 61,926 assessments were completed from 3,677 patients (Site 1 = 3,346; 91.0% and Site 2 = 331; 9.0%). Patients were predominantly White (75.6%) and female (71.7%) with a median age of 50 years (IQR = 37-61). Assessments most frequently originated from rheumatology (76.0%). Nonadherence was reported 4.0% of the time, with the most common explanations being forgetfulness (33.1%) and medication being held because of a procedure or illness (29.5%). Most responses indicated perceived effectiveness as good/excellent (93.9%), with 98.5% of responses indicating no issues with tolerability. Patients who reported tolerability issues were 2.5 times more likely to report a missed dose (95% CI = 1.87-3.23, P < 0.001). An effectiveness rating of fair was associated with a 61% increase in the odds of a missed dose compared with a rating of good/excellent (95% CI = 1.33-1.94).

CONCLUSIONS

Patients filling rheumatology or MS specialty medications within health system specialty pharmacies reported high rates of medication effectiveness and adherence and low rates of issues with tolerability and HCRU. Patients who report tolerability issues or lower perceived effectiveness may benefit from additional monitoring to prevent nonadherence.

Leukocytospermia and/or Bacteriospermia: Impact on Male Infertility

Infertility is a globally underestimated public health concern affecting almost 190 million people, i.e., about 17.5% of people during their lifetime, while the prevalence of male factor infertility is about 7%. Among numerous other causes, the prevalence of male genital tract infections reportedly ranges between 10% and 35%. Leukocytospermia is found in 30% of infertile men and up to 20% in fertile men. Bacterial infections cause an inflammatory response attracting leukocytes, which produce reactive oxygen species (ROS) and release cytokines, both of which can cause damage to sperm, rendering them dysfunctional. Although leukocytospermia and bacteriospermia are both clinical conditions that can negatively affect male fertility, there is still debate about their impact on assisted reproduction outcomes and management. According to World Health Organization (WHO) guidelines, leukocytes should be determined by means of the Endtz test or with monoclonal antibodies against CD15, CD68 or CD22. The cut-off value proposed by the WHO is 1 × 106 peroxidase-positive cells/mL. For bacteria, Gram staining and semen culture are regarded as the "gold standard", while modern techniques such as PCR and next-generation sequencing (NGS) are allowing clinicians to detect a wider range of pathogens. Whereas the WHO manual does not specify a specific value as a cut-off for bacterial contamination, several studies consider semen samples with more than 103 colony-forming units (cfu)/mL as bacteriospermic. The pathogenic mechanisms leading to sperm dysfunction include direct interaction of bacteria with the male germ cells, bacterial release of spermatotoxic substances, induction of pro-inflammatory cytokines and ROS, all of which lead to oxidative stress. Clinically, bacterial infections, including "silent" infections, are treatable, with antibiotics being the treatment of choice. Yet, non-steroidal antiphlogistics or antioxidants should also be considered to alleviate inflammatory lesions and improve semen quality. In an assisted reproduction set up, sperm separation techniques significantly reduce the bacterial load in the semen. Nonetheless, contamination of the semen sample with skin commensals should be prevented by applying relevant hygiene techniques. In patients where leukocytospermia is detected, the causes (e.g. infection, inflammation, varicocele, smoking, etc.) of the leukocyte infiltration have to be identified and addressed with antibiotics, anti-inflammatories or antioxidants in cases where high oxidative stress levels are detected. However, no specific strategy is available for the management of leukocytospermia. Therefore, the relationship between bacteriospermia and leukocytospermia as well as their specific impact on functional sperm parameters and reproductive outcome variables such as fertilization or clinical pregnancy must be further investigated. The aim of this narrative review is to provide an update on the current knowledge on leukocytospermia and bacteriospermia and their impact on male fertility.

Sex Differences in Cardiovascular Management: A Call for Better Acknowledgment-Part 1 Pharmacological Differences in Women and Men; How Relevant Are They?

BACKGROUND

Sex differences (SDs) in pharmacology of cardiovascular (CV) drugs have been described previously; however, paradoxically, there are scarce recommendations in therapy based on these differences. It is of utmost importance to identify whether these SDs determine a modified clinical response and the potential practical implications for this, to provide a base for personalized medicine.

AREA OF UNCERTAINTY

The aim of this article was to outline the most important pharmacological drivers of cardiovascular drugs that differ between women and men, along with their implications and challenges in clinical practice.

DATA SOURCES

A detailed assessment of English-written resources reflecting SDs impact in CV drug pharmacology was performed using PubMed and Embase databases.

RESULTS

Despite large variations in CV drug pharmacokinetics and pharmacodynamics in individuals, correcting for height, weight, surface area, and body composition compensate for most "sex-dependent" differences. In addition, individual, cultural, and social factors significantly impact disease management in women versus men. Gender-biased prescribing patterns and gender-dependent adherence to therapy also influence outcomes. The development of sex-specific guidelines requires that they should reflect the SDs implications for the management of a disease and that the evidence should be carefully evaluated as to whether there is an adequate representation of both sexes and whether sex-disaggregated data are reported.

CONCLUSIONS

Pharmacological drivers are under the influence of an impressive number of differences between women and men. However, to establish their significance in clinical practice, an adequate representation of women in studies and the reporting of distinct results is mandatory.

Modulation of the gut microbiome and Firmicutes phylum reduction by a nutraceutical blend in the obesity mouse model and overweight humans: A double-blind clinical trial

Overweight and obesity are closely linked to gut dysbiosis/dysmetabolism and disrupted De-Ritis ratio [aspartate aminotransferase (AST)/alanine aminotransferase (ALT) ratio], which may contribute to chronic noncommunicable diseases onset. Concurrently, extensive research explores nutraceuticals, and health-enhancing supplements, for disease prevention or treatment. Thus, sedentary overweight volunteers were double-blind randomized into two groups: Novel Nutraceutical_(S) (without silymarin) and Novel Nutraceutical (with silymarin). Experimental formulations were orally administered twice daily over 180 consecutive days. We evaluated fecal gut microbiota, based on partial 16S rRNA sequences, biochemistry and endocrine markers, steatosis biomarker (AST/ALT ratio), and anthropometric parameters. Post-supplementation, only the Novel Nutraceutical group reduced Clostridium clostridioforme (Firmicutes), Firmicutes/Bacteroidetes ratio (F/B ratio), and De-Ritis ratio, while elevating Bacteroides caccae and Bacteroides uniformis (Bacteroidetes) in Brazilian sedentary overweight volunteers after 180 days. In summary, the results presented here allow us to suggest the gut microbiota as the action mechanism of the Novel Nutraceutical promoting metabolic hepatic recovery in obesity/overweight non-drug interventions.

Gender Differences in Pain Threshold, Unpleasantness, and Descending Pain Modulatory Activation Across the Adult Life Span: A Cross Sectional Study

The neurobiological underpinnings of gender differences in pain perception, and how these differences may be modified by age, are incompletely understood, placing patients at risk of suboptimal pain management. Using functional magnetic resonance imaging, we examined brain responses in the descending pain modulatory system (DPMS, specifically, dorsolateral prefrontal cortex, anterior cingulate cortex, insula, hypothalamus, amygdala, and periaqueductal gray, during an evoked pain task. We investigated the interaction of age and gender in our sample of healthy adults (27 females, 32 males, 30-86 years) on DPMS response. In a perceptually matched thermal pain paradigm, we investigated pain unpleasantness and neural responses for 3 heat pain percepts: just noticeable pain, weak pain, and moderate pain (MP). Females reported just noticeable pain at a lower temperature, but reported less unpleasantness at weak pain and MP percepts, compared to males. There was a significant age-by-gender interaction during moderate pain in the right anterior cingulate cortex and bilateral insula, such that, males had a stronger positive relationship between DPMS response and age compared to females in these regions. Our results indicate that differences in DPMS responses may explain some gender differences in pain perception and that this effect may change across the adult lifespan. PERSPECTIVE: Gender differences in pain have been well-documented but the brain mechanisms for these differences are still unclear. This article describes potential differences in brain functioning during different levels of pain that could explain differences in pain responses between men and women across the adult lifespan.

Heterogeneities of the impact of public health policies on HIV/AIDS indicators in Brazil according to sociodemographic factors: A real-life study

INTRODUCTION

The impact of specific policies on HIV care has been scarcely investigated. In this study we aimed to analyze the impact of the Treatment For All policy (TFA-2013) and the adoption of integrase strand transfer inhibitors (INSTIs-2017) as first-line therapy on clinical indicators of people living with HIV (PLHIV) in Brazil.

METHODS

We assessed the public database of Brazil's Ministry of Health and extracted data from 2009 to 2019. We investigated the impact of TFA and INSTIs with a time-series analysis of four health indicators in PLHIV: antiretroviral treatment (ART) initiation with a CD4+ count >500/mm3 ; ART initiation <1 month after the first CD4+ measurement; viral load suppression (VLS); and treatment adherence. We explored trends over time by gender, age, macroregion of residency and municipal-level social vulnerability index.

RESULTS

We included 753 316 PLHIV in 2019. Most were males (64.81%) in the 30-49 years age category (50.86%). We observed an overall improvement in all HIV clinical indicators, with notable impact of TFA on timely ART initiation and VLS, and mild impact of INSTIs on treatment adherence. Such improvements were heterogeneous, with remarkable gaps in gender, age and socioeconomic groups that have persisted over time. Indicators point to inferior outcomes among children, older adults, women and people living in socially vulnerable locations.

CONCLUSIONS

Recent Brazilian public policies have had positive impacts on key HIV clinical indicators. However, our results highlight the need for specific policies to improve HIV care for children, older adults, women and socially vulnerable groups.

Sex Differences in the Primary Prevention of Cardiovascular Diseases in a Dutch Primary Care Setting

Background

Sex differences in the primary prevention of cardiovascular diseases (CVD) have been shown, but the evidence is mixed and fragmented. In this study, we assessed sex differences in cardiovascular risk factors assessment, risk factor levels, treatment, and meeting of treatment targets, within a Dutch primary care setting.

Methods

Data were obtained from individuals aged 40 to 70 years old, without prior CVD, registered during the entire year in 2018 at one of the 51 general practices participating in the Julius General Practitioner's Network (JGPN). History of CVD was defined based on the International Classification of Primary Care (ICPC). Linear and Poisson regressions were used to investigate sex differences in risk factor assessment, risk factor levels, treatment, and meeting of treatment targets.

Results

We included 83,903 individuals (50% women). With the exception of glycated hemoglobin (HbA1c), all risk factors for CVD were more often measured in women than in men. Lipid measurements and body mass index values were higher in women, while blood pressure (BP) and HbA1c levels were higher in men, along with estimated glomerular filtration rate (eGFR) levels. Among individuals with elevated BP or cholesterol levels, no sex difference was observed in the prescription of antihypertensive medications (RR 1.00, 95% CI: 0.94-1.06) but women were less likely than men to receive lipid-lowering medications (RR 0.87, 95% CI: 0.79-0.95). Among treated individuals, women were more likely than men to meet adequate levels of blood pressure (RR 1.17, 95% CI: 1.09-1.25) and less likely to meet target levels of cholesterol (RR 0.90, 95% CI: 0.83-0.98).

Conclusion

While women were more likely to have their CVD risk factors measured, they were less likely to be prescribed lipid-lowering medications and to meet target levels. When treated, men were less likely to achieve adequate blood pressure control.

Descriptive analysis on disproportionate medication errors and associated patient characteristics in the Food and Drug Administration's Adverse Event Reporting System

BACKGROUND

Medication errors (MEs) are a major public health concern which can cause harm and financial burden within the healthcare system. Characterizing MEs is crucial to develop strategies to mitigate MEs in the future.

OBJECTIVES

To characterize ME-associated reports, and investigate signals of disproportionate reporting (SDRs) on MEs in the Food and Drug Administration's Adverse Event Reporting System (FAERS).

METHODS

FAERS data from 2004 to 2020 was used. ME reports were identified with the narrow Standardised Medical Dictionary for Regulatory Activities® (MedDRA®) Query (SMQ) for MEs. Drug names were converted to the Anatomical Therapeutic Chemical (ATC) classification. SDRs were investigated using the reporting odds ratio (ROR).

RESULTS

In total 488 470 ME reports were identified, mostly (59%) submitted by consumers and mainly (55%) associated with females. Median age at time of ME was 57 years (interquartile range: 37-70 years). Approximately 1 out of 3 reports stated a serious health outcome. The most prevalent reported drug class was "antineoplastic and immunomodulating agents" (25%). The most common ME type was "incorrect dose administered" (9%). Of the 1659 SDRs obtained, adalimumab was the most common drug associated with MEs, noting a ROR of 1.22 (95% confidence interval: 1.21-1.24).

CONCLUSION

This study offers a first of its kind characterization of MEs as reported to FAERS. Reported MEs are frequent and may be associated with serious health outcomes. This FAERS data provides insights on ME prevention and offers possibilities for additional in-depth analyses.

Medication Adherence With Polypill in Cardiovascular Disease and High-Risk Patients: A Systematic Review and Meta-Analysis of Randomized Controlled Trials Involving 7364 Participants

Considering the worldwide mortality and morbidity of cardiovascular diseases (CVDs), the necessity of using multiple pills due to the chronicity of this condition, and the importance of medication adherence in these patients, we conducted this systematic review and meta-analysis to assess the polypill effect on adherence in patients with established CVD and at high risk. To accomplish this review, we searched various databases to access grey literature and several electronic databases to find randomized controlled trials (RCTs) assessing polypills compared to individual pills from January 2000 to October 2022. The outcomes were primarily medication adherence, secondarily systolic blood pressure (SBP), low-density lipoprotein cholesterol (LDL-C) serum level, and serious adverse events (SAEs). Ultimately, 2820 studies were detected and narrowed to 8 RCTs based on the eligibility criteria. In this study, involving 7364 patients, there was a significant improvement in medication adherence in the polypill group compared to the individual pills group (Risk Ratio [RR] = 1.29; [95%CI: 1.10; 1.50]). Out of secondary outcomes, SBP was significantly decreased (Mean Difference [MD] = -1.72 mmHg; [95%CI: -2.40; 1.03]), but LDL-C serum level (MD = -0.65 mg/dl; [95%CI: -4.47; 3.16]) and SAE (RR = 1.08; [95%CI: f0.98; 1.20]) did not have a notable difference in polypill compared to individual pills.

Is the Current Cut Point for Glycated Haemoglobin (HbA1c) Correct for Diagnosing Diabetes Mellitus in Premenopausal Women? Evidence to Inform Discussion

INTRODUCTION

Women are on average diagnosed with diabetes mellitus at later age than men but have higher mortality. As the diagnosis of diabetes mellitus is primarily based on HbA1c, the use of a non-specific reference range and cut point for diabetes mellitus that does not account for gender differences in diabetes could potentially lead to underdiagnosis of diabetes mellitus in women and missed opportunities for intervention. We investigated whether a contributing factor to the later diagnosis in women may be a difference in distribution of HbA1c in premenopausal women versus men of the same age by comparing HbA1c values in men and women across multiple sites in the UK.

METHODS

We analysed the HbA1c levels of 146,907 individuals who underwent single testing only and had HbA1c ≤ 50 mmol/mol between 2012 and 2019 in one laboratory (cohort 1). This was replicated in six laboratories with 938,678 individuals tested between 2019 and 2021 (cohort 2).

RESULTS

In cohort 1, women < 50 years old had an HbA1c distribution markedly lower than that in men by a mean of 1.6 mmol/mol (p < 0.0001), while the difference in the distribution of HbA1c for individuals aged ≥ 50 years was less pronounced (mean difference 0.9 mmol/mol, p < 0.0001). For individuals under the age of 50, HbA1c in women lagged by up to 10 years compared to men. Similar findings were found in cohort 2. We estimated an additional 17% (n = 34,953) of undiagnosed women aged < 50 years in England and Wales could be reclassified to have diabetes mellitus, which may contribute to up to 64% of the difference in mortality rates between men/women with diabetes mellitus aged 16-50 years.

CONCLUSION

The HbA1c cut point for diagnosis of diabetes mellitus may need to be re-evaluated in women under the age of 50 years. Early identification of diabetes mellitus in women has the potential to improve women's health outcomes in the longer term.

Predictors of older patients' willingness to have medications deprescribed: A cross-sectional study

BACKGROUND

Deprescribing is a complex process requiring a patient-centred approach. One frequently expressed deprescribing barrier is patients' attitudes and beliefs towards deprescribing. This study aimed to identify the predictors of patients' willingness to have medications deprescribed.

METHODS

A cross-sectional study was conducted with community-dwelling patients aged ≥65 who are taking at least one regular medication. Data collection included patients' demographic and clinical characteristics and the Portuguese revised Patients' Attitudes Towards Deprescribing (rPATD) questionnaire. Descriptive statistics were used to present the patients' characteristics. Multiple binary logistic regression analysis was performed to identify the predictors of the patients' willingness to have medications deprescribed.

RESULTS

One hundred ninety-two participants (median age 72 years; 65.6% female) were included. Most (83.33%) were willing to have medications deprescribed, and the predictors were age (adjusted odds ratio [aOR] = 1.136; 95% CI 1.026, 1.258), female sex (aOR = 3.036; 95% CI 1.059, 8.708) and the rPATD concerns about stopping factor (aOR = 0.391; 95% CI 0.203, 0.754).

CONCLUSIONS

Most patients were willing to have their medications deprescribed if it is recommended by their doctors. Older age and female sex increased the odds of willingness to deprescribe; higher concerns about stopping medications decreased the odds. These findings suggest that addressing patients' concerns about stopping their medicines may contribute to deprescribing success.

Sex differences in the management of atherosclerotic cardiovascular disease

Disparities between women and men persist in the diagnosis, treatment, and prognosis of atherosclerotic cardiovascular disease (ASCVD). Despite growing attention to sex-based differences in cardiovascular care, there are continued disparities in short- and long-term outcomes. Such disparities highlight the need to identify pathophysiologic differences in treatment patterns for stable ischemic heart disease, non-ST elevation myocardial infarction (NSTE-ACS), ST-elevation myocardial infarction (STEMI), and myocardial infarction with non-obstructive coronary arteries (MINOCA). The role of age as an effect modifier should also be considered given that young women diagnosed with ACS continue to experience increased rates of in-hospital mortality and major adverse cardiovascular events. Both patient-directed and systems-based approaches remain integral to improve outcomes in cardiovascular care. While inadequate representation of women in clinical trials remains a barrier to the implementation of evidence-based therapies, a growing body of data has established the efficacy and safety of medications in women across acute coronary syndromes. This review seeks to feature existing data on the differential treatment guidelines, care implementation, and cardiovascular outcomes between women and men, highlighting next directions for clinical investigation.

Investigating the Effect of Adherence to Antipsychotic Therapy on the Length of Stay and Number of Hospitalizations in Patients with Schizophrenia - A Descriptive Analysis

Background

Optimizing long-term outcomes in schizophrenia treatment requires effective pharmacological interventions. Medication adherence is known to influence clinical outcomes, yet there is a scarcity of studies examining its correlation with factors like Length of Stay (LOS) and re-hospitalization frequency. These outcomes are crucial indicators of how medication adherence affects overall patient well-being.

Purpose

This study aims to describe the effect of medication adherence on the length of stay (LOS) and number of hospitalizations in patients with schizophrenia.

Patients and Methods

A total of 157 subjects from the West Java Psychiatric Hospital were included in this cross-sectional retrospective study. Data, including demographics, comorbidities, duration of illness, antipsychotic adherence, LOS, and the number of hospitalizations, were collected from the patients' medical records. All the data were analyzed using the Chi-Square (χ²) test with a significance level set at p < 0.05.

Results

Our findings showed that 88% of all schizophrenia inpatients were in the nonadherence group. The highest (40.7%) LOS (>30 days) was found in the non-adherence group with discontinued therapy/stopped therapy group, while the highest percentage of patients with less than five hospitalizations was identified in the obedient and regular therapy group (94.4%). In the statistical results, we observed a significant association between therapy adherence (p = 0.043) and therapy regimen (p = 0.014) with gender. Additionally, the distinction between male and female schizophrenia patients demonstrated statistical significance (p = 0.000).

Conclusion

In this study, therapy adherence and therapy regimen were found to have a significant association with gender, as well as differences between the number of male and female schizophrenia patients that were statistically significant. While other variables may exhibit clinical associations, their statistical significance has not been fully depicted. The results of this study could be preliminary study for subsequent observational studies.

Prevalence of Nonadherence to Medications among Geriatric Patients in Al-Madinah Al-Munawara City's Hospitals, Kingdom of Saudi Arabia

Introduction

Medication adherence is a major component in the treatment of chronic patients, especially the older adults. It acts as an essential part of a successful therapeutic outcome, increasing treatment benefits, and decreasing hospital admissions, health care utilization, and cost. Limited research regarding medication adherence has been conducted nationwide; however, data among the older adults is sparse due to the lack of research on this topic. Therefore, this study aimed to determine the prevalence of medication nonadherence among older adults' Saudi patients with chronic diseases living in Al-Madinah Al-Munawwarah city.

Method

A cross-sectional study was conducted on outpatient older patients with chronic diseases who visited clinics at different hospitals in Al-Madinah Al-Munawwarah city, from March until December 2022. The questionnaire was published in a conversational Arabic dialect. The adherence level was measured by the Adherence to Refills and Medications Scale (ARMS) and the reasons for medication nonadherence were collected by using the Cluig scale.

Results

65.1% of females and 34.9% of males have participated in this study. According to the ARMS scale, 67.9% of patients had poor medication adherence and 32.1% had good medication adherence. Poor adherence was higher in females compared to males, with a p value = 0.018. For educational level, the ARMS score in graduates was higher than patients who finished middle school and illiterate patients. Based on the Cluig scale, the most common reasons for medication nonadherence were forgetfulness, feeling well, polypharmacy, and subsequent avoidance of side effects. The findings indicate the gender-based differences in the factors that associated with medication nonadherence among older adults.

Conclusion

Medication adherence is crucial especially among older adults to improve clinical outcomes. The current results highlight the prevalence of medication adherence among the older adult population. This result shows the gender-based differences in the factors associated with medication nonadherence among the older adult population.

Neurological, Behavioral, and Pathophysiological Characterization of the Co-Occurrence of Substance Use and HIV: A Narrative Review

Combined antiretroviral therapy (cART) has greatly reduced the severity of HIV-associated neurocognitive disorders in people living with HIV (PLWH); however, PLWH are more likely than the general population to use drugs and suffer from substance use disorders (SUDs) and to exhibit risky behaviors that promote HIV transmission and other infections. Dopamine-boosting psychostimulants such as cocaine and methamphetamine are some of the most widely used substances among PLWH. Chronic use of these substances disrupts brain function, structure, and cognition. PLWH with SUD have poor health outcomes driven by complex interactions between biological, neurocognitive, and social factors. Here we review the effects of comorbid HIV and psychostimulant use disorders by discussing the distinct and common effects of HIV and chronic cocaine and methamphetamine use on behavioral and neurological impairments using evidence from rodent models of HIV-associated neurocognitive impairments (Tat or gp120 protein expression) and clinical studies. We also provide a biopsychosocial perspective by discussing behavioral impairment in differentially impacted social groups and proposing interventions at both patient and population levels.

Gender-Related Factors in Medication Adherence for Metabolic and Cardiovascular Health

This review explores the impact of gender on medication adherence in the context of metabolic and cardiovascular diseases. Optimal adherence to medication is crucial for achieving treatment goals and preventing adverse outcomes in chronic diseases. The review examines specific conditions such as type 2 diabetes, hypercholesterolemia, arterial hypertension, cardiovascular diseases, and heart failure. In type 2 diabetes, female sex, younger age, new drug prescription, non-white ethnicity, low education level, and low income were identified as predictors of non-adherence. Depressive disorders were also found to influence adherence. In hypercholesterolemia, women exhibited poorer adherence to statin therapy compared to men, with statin-related side effects and patient perception being significant factors. Adherence to anti-hypertensive therapy showed conflicting results, with studies reporting both higher and lower adherence in women. Limited evidence suggests that women may have poorer adherence after acute myocardial infarction and stroke. Regarding heart failure, adherence studies have shown inconsistent findings. The reasons for gender differences in medication adherence are multifactorial and include sociodemographic, disease-related, treatment-related, and psychological factors. This review emphasizes the need for further research to better understand these differences and develop gender-customized interventions that can improve medication adherence and reduce the burden of metabolic and cardiovascular diseases.

Sex-based differences in the association between loneliness and polypharmacy among older adults in Ontario, Canada

BACKGROUND

Emerging evidence shows loneliness is associated with polypharmacy and high-risk medications in older adults. Despite notable sex-based differences in the prevalence in each of loneliness and polypharmacy, the role of sex in the relationship between loneliness and polypharmacy is unclear. We explored the relationship between loneliness and polypharmacy in older female and male respondents and described sex-related variations in prescribed medication subclasses.

METHODS

We performed a cross-sectional analysis of representative data from the Canadian Community Health Survey-Healthy Aging cycle (2008/2009) linked to health administrative databases in Ontario respondents aged 66 years and older. Loneliness was measured using the Three-Item Loneliness Scale, with respondents classified as not lonely, moderately lonely, or severely lonely. Polypharmacy was defined as five or more concurrently-prescribed medications. Sex-stratified multivariable logistic regression models with survey weights were used to assess the relationship between loneliness and polypharmacy. Among those with polypharmacy, we examined the distribution of prescribed medication subclasses and potentially inappropriate medications.

RESULTS

Of the 2348 individuals included in this study, 54.6% were female respondents. The prevalence of polypharmacy was highest in those with severe loneliness both in female (no loneliness, 32.4%; moderate loneliness, 36.5%; severe loneliness, 44.1%) and male respondents (32.5%, 32.2%, and 42.5%). Severe loneliness was significantly associated with greater adjusted odds of polypharmacy in female respondents (OR = 1.59; 95% CI: 1.01-2.50) but this association was attenuated after adjustment in male respondents (OR = 1.00; 95% CI: 0.56-1.80). Among those with polypharmacy, antidepressants were more commonly prescribed in female respondents with severe loneliness (38.7% [95% CI: 27.3-50.0]) compared to those who were moderately lonely (17.7% [95% CI: 9.3-26.2]).

CONCLUSIONS

Severe loneliness was independently associated with polypharmacy in older female but not male respondents. Clinicians should consider loneliness as an important risk factor in medication reviews and deprescribing efforts to minimize medication-related harms, particularly in older women.

Adherence to levothyroxine treatment among patients with hypothyroidism in Oman: a national cross-sectional study

OBJECTIVE

Hormone replacement therapy with levothyroxine is considered the treatment of choice for hypothyroidism; however, non-adherence is a major contributor to poor treatment outcomes. This study aimed to evaluate levels of drug adherence (DA) to levothyroxine therapy among Omani adults with hypothyroidism and to explore related sociodemographic and clinical factors.

METHODS

A national, multi-center, cross-sectional survey was carried out from August to December 2021 at 18 primary healthcare centers across all governorates of Oman. A total of 415 Omani adults were recruited. Data were collected using a pre-tested, Arabic-language questionnaire completed by trained researchers during face-to-face interviews with the participants. Level of DA was determined using the 8-item Morisky Medication Adherence Scale (MMAS-8).

RESULTS

A total of 400 Omani adults participated in the study (response rate: 96.4%). The mean age was 41.9 ± 12.4 years old (range: 18-78 years) and 90.3% were female. According to their MMAS-8 scores, 157 (39.2%), 139 (34.8%), and 104 (26.0%) participants demonstrated low, medium, and high DA, respectively. No significant correlations were observed between level of DA and any sociodemographic or clinical characteristics, including age, gender, education, duration of treatment, and family history of thyroid disease (p > 0.050).

CONCLUSIONS

Only a quarter of Omani patients with hypothyroidism reported high levels of adherence to levothyroxine treatment, likely as a result of lack of awareness of the disease and the importance of maintaining an euthyroid state. Further studies using more objective measures of DA are recommended to determine correlates of non-compliance to levothyroxine therapy among Omani patients.

Timely referral to health centers for the prevention of cardiovascular diseases: IraPEN national program

Introduction

The IraPEN program is an adapted version of the WHO-PEN program designed to prevent four major non-communicable diseases in Iran. This study aimed to determine the rate of compliance and related factors among individuals participating in the IraPEN program for the prevention of cardiovascular disease.

Method

In this study, compliance was defined as timely referral to the health center as scheduled, and the researchers approached four pilot sites of IraPEN from March 2016 to March 2018. Sex-stratified logistic regressions were applied to investigate factors related to compliance. However, it is important to note that in this study, compliance was defined as compliance to revisit, not compliance to taking prescribed medications or behavioral lifestyle changes.

Results

The total compliance rate, including timely compliance and early and late compliance, was 16.5% in men and 23.3% in women. The study found that cardiovascular risk factors such as diabetes, hypertension, hypercholesterolemia, and being underweight were associated with lower compliance. The higher calculated risk of CVD was associated with higher compliance, but after adjusting for cardiovascular risk factors, high-risk individuals showed lower compliance. There was negligible interaction between sex and other factors for compliance.

Conclusion

The compliance rate with scheduled programs for cardiovascular preventive strategies was very low, and high-risk individuals were less compliant, regardless of their high level of risk factors. The study recommends further training to increase awareness and knowledge regarding the IraPEN program and the prevention of non-communicable diseases among high-risk populations.

Exploring treatment effect heterogeneity of a PROMs alert intervention in knee and hip arthroplasty patients: A causal forest application

Patient reported outcome measures (PROMs) experience an uptake in use for hip (HA) and knee arthroplasty (KA) patients. As they may be used for patient monitoring interventions, it remains unclear whether their use in HA/KA patients is effective, and which patient groups benefit the most. Nonetheless, knowledge about treatment effect heterogeneity is crucial for decision makers to target interventions towards specific subgroups that benefit to a greater extend. Therefore, we evaluate the treatment effect heterogeneity of a remote PROM monitoring intervention that includes ∼8000 HA/KA patients from a randomized controlled trial conducted in nine German hospitals. The study setting gave us the unique opportunity to apply a causal forest, a recently developed machine learning method, to explore treatment effect heterogeneity of the intervention. We found that among both HA and KA patients, the intervention was especially effective for patients that were female, >65 years of age, had a blood pressure disease, were not working, reported no backpain and were adherent. When transferring the study design into standard care, policy makers should make use of the knowledge obtained in this study and allocate the treatment towards subgroups for which the treatment is especially effective.

Uptake and Spending on Biosimilar Infliximab and Etanercept After New Start and Switching Policies in Canada: An Interrupted Time Series Analysis

OBJECTIVE

Uptake of biosimilars has been suboptimal in North America. This study was undertaken to quantify the impact of various policy interventions (namely, new start and switching policies) on uptake and spending on biosimilar infliximab and etanercept in British Columbia (BC), Canada.

METHODS

We used administrative claims data to identify BC residents ≥18 years of age with rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, and/or plaque psoriasis who qualified for public drug coverage from January 2013 to November 2020. Using interrupted time series analysis, we studied the change in proportion spent on and prescriptions dispensed of biosimilar infliximab and etanercept out of the total amount per agent after new start and biosimilar switching policies were implemented.

RESULTS

Our study included 208,984 individuals living with rheumatoid arthritis, ankylosing spondylitis, plaque psoriasis, and/or psoriatic arthritis, corresponding to 5,884 patients taking infliximab and etanercept. After the new start policy, we detected a small gradual increase in the proportion of dispensed biosimilar etanercept prescriptions of 0.65% per month (95% confidence interval [95% CI] 0.44, 0.85). The trend related to the proportion of total spending on biosimilar etanercept also increased (0.51% [95% CI 0.28, 0.73]). After the switching policy, there was a sustained increase in the proportion of dispensed biosimilar etanercept and infliximab prescriptions of 76.98% (95% CI 75.56, 78.41) and 58.43% (95% CI 52.11, 64.75), respectively. Similarly, there was a persistent increase in monthly spending on biosimilar etanercept and infliximab of 78.22% (95% CI 76.65, 79.79) and 71.23% (95% CI 66.82, 75.65), respectively.

CONCLUSION

We found that mandatory switching policies were much more effective than new starting policies for increasing the use of biosimilar medications.

Pharmacotherapeutic profile, polypharmacy and its associated factors in a cohort of people living with HIV in Brazil

BACKGROUND

The increased survival provided by the access, development, and evolution of antiretroviral drugs (ARV) greatly increased the life expectancy of people living with HIV (PWH). This has also led to an increased occurrence of diseases or morbidities related to aging. In individuals with multiple comorbidities, the simultaneous use of multiple medications, also known as polypharmacy, is common, and rational use of medications is essential. This study aims to describe the pharmacotherapeutic profile, estimate the prevalence of polypharmacy and identify factors associated with polypharmacy in a cohort of adult PWH from a referral unit in Rio de Janeiro, Brazil.

METHODS

Cross-sectional study including PWH on ARV who received at least one medical prescription (outpatient/hospitalized) in 2019. We described the proportion of prescribed medications according to ARV and Anatomical Therapeutic Chemical (ATC) classes stratified by age (< 50 vs. ≥50 years). Polypharmacy was defined as ≥ 5 medications prescribed beyond ARV. Logistic regression models assessed demographic and clinical factors associated with polypharmacy.

RESULTS

A total of 143,306 prescriptions of 4547 PWH were analyzed. Median age was 44.4 years (IQR:35.4-54.1) and 1615 (35.6%) were ≥ 50 years. A total of 2958 (65.1%) participants self-identified as cisgender man, 1365 (30.0%) as cisgender woman, and 224 (4.9%) as transgender women. Most self-declared Black/Pardo (2582; 65.1%) and 1984 (44.0%) completed elementary education or less. Median time since HIV diagnosis was 10.9 years (IQR:6.2-17.7). Most frequently prescribed concomitant medications were nervous system (64.8%), antiinfectives for systemic use (60.0%), alimentary tract and metabolism (45.9%), cardiovascular system (40.0%) and respiratory system (37.1%). Prevalence of polypharmacy was 50.6% (95%CI: 49.2-52.1). Model results indicated that being older, self-identify as cisgender woman, having less education and longer time since HIV diagnosis increased the odds of polypharmacy.

CONCLUSIONS

We found high rates of polypharmacy and concomitant medication use in a cohort of PWH in Brazil. Targeted interventions should be prioritized to prevent interactions and improve treatment, especially among individuals using central nervous system and cardiovascular medications, as well as certain groups such as cisgender women, older individuals and those with lower education. Standardized protocols for continuous review of patients' therapeutic regimens should be implemented.

Exploring physician gender bias in the initiation of prescribing cascades for older men and women: a qualitative clinical vignette study protocol

INTRODUCTION

A prescribing cascade occurs when a drug is prescribed to manage the often unrecognised side effect of another drug; these cascades are of particular concern for older adults who are at heightened risk for drug-related harm. It is unknown whether, and to what extent, gender bias influences physician decision-making in the context of prescribing cascades. The aim of this transnational study is to explore the potential impact of physician implicit gender biases on prescribing decisions that may lead to the initiation of prescribing cascades in older men and women in two countries, namely: Canada and Italy.

METHODS AND ANALYSIS

Male and female primary care physicians at each site will be randomised 1:1 to a case vignette that features either a male or female older patient who presents with concerns consistent with the side effect of a medication they are taking. During individual interviews, while masked to the true purpose of the study, participants will read the vignette and use the think-aloud method to describe their ongoing thought processes as they consider the patient's concerns and determine a course of action. Interviews will be recorded, transcribed verbatim and thematic analysis will be conducted to highlight differences in decisions in the interviews/transcripts, using a common analytical framework across the sites.

ETHICS AND DISSEMINATION

This study has received ethics approval at each study site. Verbal informed consent will be received from participants prior to data collection and all data will be deidentified and stored on password-protected servers. Results of this study will be disseminated through peer-reviewed journal articles and presented at relevant national and international conferences.

Asthma and COPD: Comparison with International Guidelines and Medication Adherence in Belgium

Asthma and chronic obstructive pulmonary disease (COPD) are major chronic conditions. It is possible to limit their impact by controlling symptoms, which limits exacerbations and worsening of the disease, by choosing the appropriate treatment and ensuring that the patient adheres to it. The main purpose of this study was to assess medication adherence and persistence with inhaled medications for chronic treatment of asthma and COPD, as well as to evaluate the factors influencing this adherence. Medication adherence was measured from January 2013 to December 2016 using continuous multiple-interval measures of medication availability (CMA). Persistence was evaluated by treatment episodes (TE). We analyzed the influence of different factors on CMA such as sex, age, type of device, and the realization of the "new medicines service" (NMS), introduced in Belgium in October 2013 to support patients in adhering to their treatment. We also analyzed the consumption of these inhaled medications within the Belgian population and compared them with the Global Initiative for Asthma (GINA) and the Global Initiative for Chronic Obstructive Lung Disease (GOLD) recommendations. Medication adherence varied greatly between the different pharmacological classes: inhaled corticosteroids (ICS) alone or in combination with long-acting beta agonists (LABA) had the lowest medication adherence and persistence, while adherence was highest for the long-acting muscarinic antagonists (LAMA) and LABA/LAMA associations. The NMS seemed to have a positive impact on medication adherence, although few patients completed the two guidance interviews offered by the service. In addition, only a minority of the targeted patients took advantage of this new service.

Use and outcomes of antihypertensive medication treatment in the US hypertensive population: A gender comparison

Background

Although effective antihypertensive medications have existed for decades, only about half of the hypertensive individuals are considered to have controlled blood pressure. Limited research studies have investigated gender disparity in the utilization and effectiveness of antihypertensive medications treatment. To examine the gender difference in antihypertensive medications' use and the effect of using antihypertensive medication treatment on blood pressure control among the U.S. adult with hypertension.

Methods

Analysis of National Health and Nutrition Examination Survey (NHANES) data from (1999-2012) including individuals≥18 years old with hypertension. Study variables included gender, age, race/ethnicity, obesity, smoking, comorbidities, treatment medication type, and continuity of care. We used multivariate logistic regression in STATA V14. The data is presented as adjusted odds ratios (ORs) and 95% confidence interval (CI).

Results

Of the 15719 participants, 52% were female. 49% of the antihypertensive medication users had their blood pressure under control (95% CI). In the adjusted logistic regression analysis, use of antihypertensive medications was found to be 12% greater in females as compared to males (OR=1.12; CI=1.02-1.22; P<0.05). No association between gender and blood pressure control was found. Blood pressure control was less likely achieved among 50 years or younger individuals, Blacks and Hispanics, obese, and those taking calcium channel blocker (CCB).

Conclusion

Hypertensive females are more likely than males to use antihypertensive medications. The effectiveness of treatment to control blood pressure is equal across males and females. Our findings have implications for practitioners to account gender-specific approaches when discussing adherence to hypertension medication treatment with their patients.

Sex Differences in Heart Failure: What Do We Know?

Heart failure (HF) remains an important global health issue, substantially contributing to morbidity and mortality. According to epidemiological studies, men and women face nearly equivalent lifetime risks for HF. However, their experiences diverge significantly when it comes to HF subtypes: men tend to develop HF with reduced ejection fraction more frequently, whereas women are predominantly affected by HF with preserved ejection fraction. This divergence underlines the presence of numerous sex-based disparities across various facets of HF, encompassing aspects such as risk factors, clinical presentation, underlying pathophysiology, and response to therapy. Despite these apparent discrepancies, our understanding of them is far from complete, with key knowledge gaps still existing. Current guidelines from various professional societies acknowledge the existence of sex-based differences in HF management, yet they are lacking in providing explicit, actionable recommendations tailored to these differences. In this comprehensive review, we delve deeper into these sex-specific differences within the context of HF, critically examining associated definitions, risk factors, and therapeutic strategies. We provide a specific emphasis on aspects exclusive to women, such as the impact of pregnancy-induced hypertension and premature menopause, as these unique factors warrant greater attention in the broader HF discussion. Additionally, we aim to clarify ongoing controversies and knowledge gaps pertaining to the pharmacological treatment of HF and the sex-specific indications for cardiac implantable electronic devices. By shining a light on these issues, we hope to stimulate a more nuanced understanding and promote the development of more sex-responsive approaches in HF management.

Gender Differences in Potentially Inappropriate Medication Use among Older Adults

BACKGROUND

Use of potentially inappropriate medication (PIMs) is a prominent concern that leads to significant medication-related issues among older adults. Notably, older women tend to utilize more medicines than men; older women frequently take more drugs. In addition, some evidence suggests that prescription PIMs vary by gender. This study examines the gender-based variation in prescribing PIM among older adults in Saudi Arabia.

METHODS

A cross-sectional retrospective analysis of electronic medical records from a large hospital in Saudi Arabia was carried out. Patients over the age of 65 who received ambulatory treatment were included in the study. The utilization of PIM was assessed based on Beers criteria. Descriptive statistics and logistic regression were employed to describe patterns of PIM utilization and identify factors associated with their use. All statistical analyses were performed using Version 9.4 of the Statistical Analysis Software (SAS^® 9.4).

RESULTS

The study comprised 4062 older people (age 65) who visited ambulatory care clinics; the average age was (72.6 ± 6.2) years. The majority of the study sample was women (56.8%). Among older adults, 44.7% of older men and 58.3% of older women reported having PIMs that should be avoided, indicating a higher prevalence of PIMs among women compared to men. In terms of the PIM categories used, women had a much higher utilization rate of cardiovascular and gastrointestinal drugs than men. In men, the use of PIMs was frequently associated with hypertension, ischemic heart disease, asthma, osteoarthritis, and cancer, while in women PIM use was associated with age, dyslipidemia, chronic kidney disease, and osteoporosis.

CONCLUSIONS

This study revealed sex differences in PIM prescribing among older adults; PIM use is more common among women. Sex differences exist in clinical and socioeconomic characteristics and factors related to using potentially inappropriate medications. This study revealed essential areas that could be targeted by further interventions to improve drug-prescribing practices among older adults at risk of PIM.

Sex-Related Differences in the Pharmacological Response in SARS-CoV-2 Infection, Dyslipidemia, and Diabetes Mellitus: A Narrative Review

Pharmacological responses vary by sex in several illnesses. This narrative review summarizes sex variations in pharmaceutical response in SARS-CoV-2 infection, dyslipidemia, and diabetes mellitus. Infection with SARS-CoV-2 is more severe and deadly in men than women. This may be attributed to immunological responses, genetics, and hormones. Some research shows that men may respond better to genomic vaccinations and females to antiviral medications such as remdesivir (Moderna and Pfizer-BioNTech). In dyslipidemia, women tend to have greater HDL-C and lower LDL-C than men. Some studies show that females may need lower statin dosages than men to obtain equal LDL-C reductions. Ezetimibe co-administered with a statin significantly improved lipid profile indicators in men compared to women. Statins reduce dementia risk. Atorvastatin decreased dementia risk in males (adjusted HR 0.92, 95% CI 0.88-0.97), whereas lovastatin lowered dementia risk in women (HR 0.74, 95% CI 0.58-0.95). In diabetes mellitus, evidence suggests that females may have a higher risk of developing certain complications such as diabetic retinopathy and neuropathy, despite having lower rates of cardiovascular disease than males. This could be the result of differences in hormonal influences and genetic factors. Some research shows females may respond better to oral hypoglycemic medications such as metformin. In conclusion, sex-related differences in pharmacological response have been observed in SARS-CoV-2 infection, dyslipidemia, and diabetes mellitus. Further research is needed to better understand these differences and to develop personalized treatment strategies for males and females with these conditions.
