COVID-19 and diabetes: Is there enough evidence?

Post-COVID-19 inflammation and sarcopenia in obese diabetic dialysis patients

INTRODUCTION

Diabetes, obesity, and CKD collectively impact musculoskeletal health and increase the risk of severe coronavirus disease 2019 (COVID-19) outcomes.

METHODS

This cross-sectional study included 32 dialysis patients, categorized based on their COVID-19 status. Laboratory assessments included inflammatory markers (IL-1β, IL-6, IL-8, and TNF-α). Sarcopenia risk was evaluated using the strength, assistance with walking, rising from a chair, climbing stairs, and falls (SARC-F) questionnaire, bioimpedance analysis, and static muscle strength testing.

RESULTS

No significant differences were observed between groups in laboratory values, sarcopenia risk, or inflammatory markers. Body composition, SARC-F scores, and static muscle strength were comparable across both groups, except for elevated parathyroid hormone (PTH) levels in Group A (p = 0.008).

CONCLUSION

The lack of association between the inflammatory response and sarcopenia risk may be attributed to the existing inflammatory status of this population, given the coexistence of diabetes, CKD, and obesity. Notably, all studied laboratory variables showed no significant differences, except for the higher PTH levels.

Proposed Mechanisms for the Relationship between Periodontal Diseases and the Severity of Covid-19: Common Pathogens, Inflammatory Mediators, and Risk Factors

Periodontal disease (PD) is a chronic inflammatory disease with some cytokine involvement, associated with several risk factors such as diabetes, obesity, etc., Corona Virus Disease 2019 (COVID-19), a new viral infection, also appears to be related to cytokine storm and similar risk factors. In this review, we intend to evaluate the possible relationship between PD and COVID-19. For data collection, English literature was searched in databases including PubMed and Google Scholar. The keywords searched were COVID-19, SARS-CoV-2, PD, respiratory Impact of Oral pathogens on respiratory diseases: Epidemiological studies indicated that oral pathogens are related to acute and chronic lung disease, and dental plaque is a likely reservoir for respiratory pathogens. Viral presence in the periodontal pocket: SARS-CoV-2 may be released from infected periodontal cells into periodontal pockets. Common inflammatory mediators: Several studies showed that the serum levels of interleukins (IL)-1, 6, 17, etc., increase in most patients with severe COVID-19. C-reactive protein (CRP) and endothelin 1(ET-1) may also be related to COVID-19 progression, and these mediators also increase in periodontitis. Common risk factors: Due to studies, diabetes mellitus (DM), obesity, aging, and male sex are the most important risk factors common between PDs and COVID-19 and may affect treatment outcomes and prognosis. PD seems to play a significant role in exacerbating COVID-19 and even affects the mortality rate of disease.

Joint modeling of longitudinal and competing risks for assessing blood oxygen saturation and its association with survival outcomes in COVID-19 patients

BACKGROUND

The objective of the present study is to evaluate the association between longitudinal and survival outcomes in the presence of competing risk events. To illustrate the application of joint modeling in clinical research, we assessed the blood oxygen saturation (SPO2) and its association with survival outcomes in coronavirus disease (COVID-19).

MATERIALS AND METHODS

In this prospective cohort study, we followed 300 COVID-19 patients, who were diagnosed with severe COVID-19 in the Rohani Hospital in Babol, the north of Iran from October 22, 2020 to March 5, 2021, where death was the event of interest, surviving was the competing risk event and SPO2 was the longitudinal outcome. Joint modeling analyses were compared to separate analyses for these data.

RESULT

The estimation of the association parameter in the joint modeling verified the association between longitudinal outcome SPO2 with survival outcome of death (Hazard Ratio (HR) = 0.33, P = 0.001) and the competing risk outcome of surviving (HR = 4.18, P < 0.001). Based on the joint modeling, longitudinal outcome (SPO2) decreased in hypertension patients (β = -0.28, P = 0.581) and increased in those with a high level of SPO2 on admission (β = 0.75, P = 0.03). Also, in the survival submodel in the joint model, the risk of death survival outcome increased in patients with diabetes comorbidity (HR = 4.38, P = 0.026).

CONCLUSION

The association between longitudinal measurements of SPO2 and survival outcomes of COVID-19 confirms that SPO2 is an important indicator in this disease. Thus, the application of this joint model can provide useful clinical evidence in the different areas of medical sciences.

Comparison of time to negative conversion of SARS-CoV-2 between young and elderly among asymptomatic and mild COVID-19 patients: a cohort study from a national containment center

Objective

We aimed to study the relationship between age and time to negative conversion of SARS-CoV-2 in patients with asymptomatic and mild forms of COVID-19.

Methods

We conducted a cohort study including all patients diagnosed with COVID-19 from the national COVID-19 containment center of Tunisia. Patients were subdivided into two cohorts: (under 60 years) and (over 60 years) and were followed up until PCR negativization. Log rank test and Cox regression were applied to compare time to negative conversion between the old group and the young group.

Results

The study included 289 patients with non-severe forms of COVID-19. Age over 60 was significantly associated with delayed negative conversion in male sex (Hazard ratio (HR): 1.9; 95% CI: 1.2-3.07) and among patients with morbid conditions (HR:1.68; 95% CI: 1.02-2.75) especially diabetics (HR: 2.06; 95% CI: 1.01-4.21). This association increased to (HR:2.3; 95% CI: 1.13-4.66) when male sex and comorbidities were concomitantly present and rose to (HR: 2.63; 95% CI: 1.02-6.80) for men with diabetes. Cox regression analysis revealed a significantly delayed negative conversion in symptomatic patients. Significant interaction was observed between gender and age and between age and chronic conditions.

Conclusion

Age is associated with delayed negative conversion of viral RNA in certain subgroups. Identifying these subgroups is crucial to know how prioritize preventive strategies in elderly.

[Association between SARS-COV-2 and chronic diseases in health personnel. A preventive medicine program]

Objective

The SARS-CoV-2 infection has been linked to hypertension, obesity and diabetes as risks of hospitalization and death. Regarding obstructive pulmonary diseases, the scientific literature is diverse; finding variation in the frequency of these and therefore their relationship with COVID-19. The available evidence only details hospitalized patients, with insufficient information referring to health workers, so analyzing the main comorbidities in this group is helpful for the implementation and improvement of preventive programs. The objective of this study was to describe the prevalence and association of comorbidities with SARS-CoV-2 infection in health care workers.

Methods

Analytical cross-sectional study, in workers of the main national reference center for respiratory diseases in Mexico, who came to care to rule out SARS-CoV-2 infection through a preventive program; calculation of proportions was performed for the sample size. Summary and association measures were calculated.

Results

The prevalence of COVID-19 was 22.9 %. The most frequent comorbidities were: overweight obesity, smoking, hypertension, allergic rhinitis and asthma, with prevalences of 29.0 %, 13.2 %, 8.6 %, 5.5 %, 3.9%, 2.8 % respectively. Overweight, obesity and vaccination against SARS-CoV-2 had Prevalence Ratios of 1.78, 1.72 and 0.43 respectively.

Conclusions

Obesity and overweight show association with SARS-CoV-2; vaccination is a protective factor, especially in people with comorbidities.

A 14-year-old boy with multiple trauma and bilateral basal ganglia hemorrhage due to coronavirus disease 2019: a case report

BACKGROUND

In December 2019, coronavirus disease 2019 spread worldwide, causing acute respiratory distress syndrome. Coronavirus disease 2019 presents from an asymptomatic infection to severe disease causing multiorgan failure. Neurological manifestations were observed in some patients, including intracerebral hemorrhage. Bilateral basal ganglia hemorrhage is rare due to trauma.

CASE PRESENTATION

Our patient was a 14-year-old Iranian boy with multiple trauma and loss of consciousness who tested positive for coronavirus disease 2019. The brain computed tomography scan reported bilateral basal ganglia hemorrhage. Bilateral ground glass opacity was reported through a chest computed tomography scan.

DISCUSSION AND CONCLUSIONS

In this study, we reported a 14-year-old boy referred to the emergency room due to multiple trauma. Through the medical interventions, bilateral basal ganglia hemorrhage was discovered incidentally. Coronavirus disease 2019 was detected in this patient on the basis of findings in chest computed tomography scan and positive real reverse transcription polymerase chain reaction test. Several clinical reports and series exploring the relationship between coronavirus disease 2019 and ischemic strokes have been published. Coronavirus disease 2019, like other acute respiratory syndromes, can invade the central nervous system through hematogenous and neuronal dissemination or it can be an immune response to the cytokine storm. In conclusion, it is vital to know the pathophysiology of the neurological manifestations of coronavirus disease 2019 and prevent the mild neurological manifestations leading to severe conditions.

Predictors of intensive care unit length of stay and mortality among unvaccinated COVID-19 patients in Jordan

Background

Factors associated with mortality and intensive care unit (ICU) admission due to Coronavirus Disease 2019 (COVID-19) in Jordanian patients are not known particularly among unvaccinated patients.

Aim

To examine predictors of mortality and ICU stay in unvaccinated COVID-19 patients in the north of Jordan.

Methods

Patients admitted with COVID-19 between October-December 2020 were included. Data on baseline clinical and biochemical characteristics, length of ICU stay, COVID-19 complications and mortality were collected retrospectively.

Findings

567 COVID-19 patients were included. The mean age was 64.64±0.59 years. 59.9% of patients were males. The mortality rate was 32.3%. Underlying cardiovascular disease or diabetes mellitus was not associated with mortality. The mortality increased with the number of underlying diseases. Independent predictors of ICU stay were neutrophil/lymphocyte ratio, invasive ventilation, the development of failure, myocardial infarction, stroke and venous thromboembolism. The use of multivitamins was observed to be negatively associated with ICU stay. Independent predictors of mortality were age, underlying cancer, severe COVID-19, neutrophil/lymphocyte ratio, C-reactive protein (CRP), creatinine level, pre-use of antibiotics, ventilation during hospitalisation, and length of ICU stay.

Conclusion

COVID-19 was associated with an increased length of ICU stay and mortality among unvaccinated COVID-19 patients. The prior use of antibiotics was also associated with mortality. The study highlights the need for close monitoring of respiratory and vital signs, inflammatory biomarkers such as WBC and CRP, and prompt ICU care in COVID-19 patients.

Clinical Risk Factors of Need for Intensive Care Unit Admission of COVID-19 Patients; a Cross-sectional Study

Introduction

It could be beneficial to accelerate the hospitalization of patients with the identified clinical risk factors of intensive care unit (ICU) admission, in order to control and reduce COVID-19-related mortality. This study aimed to determine the clinical risk factors associated with ICU hospitalization of COVID-19 patients.

Methods

The current research was a cross-sectional study. The study recruited 7182 patients who had positive PCR tests between February 23, 2020, and September 7, 2021 and were admitted to Afzalipour Hospital in Kerman, Iran, for at least 24 hours. Their demographic characteristics, underlying diseases, and clinical parameters were collected. In order to analyze the relationship between the studied variables and ICU admission, multiple logistic regression model, classification tree, and support vector machine were used.

Results

It was found that 14.7 percent (1056 patients) of the study participants were admitted to ICU. The patients' average age was 51.25±21 years, and 52.8% of them were male. In the study, some factors such as decreasing oxygen saturation level (OR=0.954, 95%CI: 0.944-0.964), age (OR=1.007, 95%CI: 1.004-1.011), respiratory distress (OR=1.658, 95%CI: 1.410-1.951), reduced level of consciousness (OR=2.487, 95%CI: 1.721-3.596), hypertension (OR=1.249, 95%CI: 1.042-1.496), chronic pulmonary disease (OR=1.250, 95%CI: 1.006-1.554), heart diseases (OR=1.250, 95%CI: 1.009-1.548), chronic kidney disease (OR=1.515, 95%CI: 1.111-2.066), cancer (OR=1.682, 95%CI: 1.130-2.505), seizures (OR=3.428, 95%CI: 1.615-7.274), and gender (OR=1.179, 95%CI: 1.028-1.352) were found to significantly affect ICU admissions.

Conclusions

As evidenced by the obtained results, blood oxygen saturation level, the patient's age, and their level of consciousness are crucial for ICU admission.

COVID-19 Vaccination and Diabetes Mellitus: How Much Has It Made a Difference to Outcomes Following Confirmed COVID-19 Infection?

INTRODUCTION

Since early 2020 the whole world has been challenged by the SARS-CoV-2 virus (COVID-19), its successive variants and the associated pandemic caused. We have previously shown that for people living with type 2 diabetes (T2DM), the risk of being admitted to hospital or dying following a COVID-19 infection progressively decreased through the first months of 2021. In this subsequent analysis we have examined how the UK COVID-19 vaccination programme impacted differentially on COVID-19 outcomes in people with T1DM or T2DM compared to appropriate controls.

METHODS

T1DM and T2DM affected individuals were compared with their matched controls on 3:1 ratio basis. A 28-day hospital admission or mortality was used as the binary outcome variable with diabetes status and vaccination for COVID-19 as the main exposure variables.

RESULTS

A higher proportion of T1DM individuals vs their controls was found to be vaccinated at the point of their first recorded positive COVID-19 test when compared to T2DM individuals vs their controls. Regarding the 28-day hospital admission rate, there was a greater and increasing protective effect of subsequent vaccination dosage (one, two or three) in mitigating the effects of COVID-19 infection versus no vaccination in T1DM than in T2DM individuals when compared with matched controls. Similar effects were observed in T2DM for death. Across both diabetes and non-diabetes individuals, those at greater socio-economic disadvantage were more likely to test positive for COVID-19 in the early phase of the pandemic. For T2DM individuals socio-economic disadvantage was associated with a greater likelihood of hospital admission and death, independent of vaccination status. Age and male sex were also independently associated with 28-day hospital admission in T2DM and to 28-day mortality, independent of vaccination status. African ethnicity was also an additional factor for hospital admission in people with T2DM.

CONCLUSION

A beneficial effect of COVID-19 vaccination was seen in mitigating the harmful effects of COVID-19 infection; this was manifest in reduced hospital admission rate in T1DM individuals with a lesser effect in T2DM when compared with matched controls, regarding both hospital admission and mortality. Socio-economic disadvantage influenced likelihood of COVID-19 confirmed infection and the likelihood of hospital admission/death independent of the number of vaccinations given in T2DM.

Knowledge, attitude and practices regarding COVID-19 and their associated factors in patients with type 2 diabetes attending Abdullah-Khalil diabetes center, Omdurman: A cross-sectional study

Novel corona virus disease 2019 is the major threat for human life nowadays worldwide. This study aims to assess the knowledge, attitude and practices regarding COVID-19 among patients with type 2 diabetes attending Abdullah Khalil diabetes center (Omdurman Teaching Hospital). A facility-based observational descriptive cross-sectional study was carried out between January and February 2021, using non-probability quota sampling technique in Abdullah-Khalil diabetes center via the use of a structured close-ended interview questionnaire. It consisted of 19, 10, and 10 questions pertaining to knowledge, attitude and practices towards COVID-19 respectively. A total of 249 patients with type 2 diabetes were included. Of them, 132 (53.0%) were females and the majority (53.0%) aged between 41 and 60 years old. Concerning their education and marital status, 70 (28.1%) were primary school level and 208 (83.5%) were married. 89.6% of participants reported mass media as main source of information regarding COVID-19. Patients with type 2 diabetes attending Abdullah-Khalil diabetes center have good knowledge, positive attitude and good prevention practices towards COVID-19. Most respondents had good knowledge, positive attitude and good practices as 78.7%, 97.6%, and 69.9%, respectively. Educational level and source of information showed statistically significant association with the knowledge, attitude. However, the practice showed only statistical association with the mass media as a source of information (P = .006).

A global spatial analysis of factors associated with case and mortality rates for coronavirus disease 2019 during the first year of the pandemic

BACKGROUND

A increasing number of studies have revealed associations between country-level determinants and coronavirus disease 2019 (COVID-19) outcomes. This ecological study was conducted to analyze country-level parameters related to COVID-19 infections and deaths during the first year of the pandemic.

METHODS

The examined predictors comprised demographics, economic factors, disease prevalence and healthcare system status, and the relevant data were obtained from public databases. The index dates were set to 15 July 2020 (Time 1) and 15 December 2020 (Time 2). The adjusted spatial autoregression models used a first-order queen contiguity spatial weight for the main analysis and a second-order queen contiguity spatial weight for a sensitivity analysis to examine the predictors associated with COVID-19 case and mortality rates.

RESULTS

Obesity was significantly and positively associated with COVID-19 case and mortality rates in both the main and sensitivity analyses. The sensitivity analysis revealed that a country's gross domestic product, population density, life expectancy and proportion of the population older than 65 y are positively associated with COVID-19 case and mortality rates.

CONCLUSIONS

With the increasing global prevalence of obesity, the relationship between obesity and COVID-19 disease at the country level must be clarified and continually monitored.

Utilization Patterns and Outcomes of People With Diabetes and COVID-19: Evidence From United States Medicare Beneficiaries in 2020

Objective

Determine differences in utilization patterns, disease severity, and outcomes between patients with and without diabetes mellitus diagnosed with COVID-19 in 2020

Research Design and Methods

We used an observational cohort comprised of Medicare fee-for-service beneficiaries with a medical claim indicating a COVID-19 diagnosis. We performed inverse probability weighting between beneficiaries with and without diabetes to account for differences in socio-demographic characteristics and comorbidities.

Results

In the unweighted comparison of beneficiaries, all characteristics were significantly different (P&lt;0.001). Beneficiaries with diabetes were younger, more likely to be black, had more comorbidities, higher rates of Medicare-Medicaid dual-eligibility, and were less likely to be female. In the weighted sample, hospitalization rates for COVID-19 among beneficiaries with diabetes was higher (20.5% vs 17.1%; p &lt; 0.001). Outcomes of hospitalizations were similarly worse among beneficiaries with diabetes: admissions to ICU during hospitalizations (7.78% vs. 6.11%; p &lt; 0.001); in-hospital mortality (3.85% vs 2.93%; p &lt; 0.001); and ICU mortality (2.41% vs 1.77%). Beneficiaries with diabetes had more ambulatory care visits (8.9 vs. 7.8, p &lt; 0.001) and higher overall mortality (17.3% vs. 14.9%, p &lt; 0.001) following COVID-19 diagnosis.

Conclusion

Beneficiaries with diabetes and COVID-19 had higher rates of hospitalization, ICU use and overall mortality. While the mechanism of how diabetes impacts the severity of COVID-19 may not be fully understood, there are important clinical implications for persons with diabetes. A diagnosis of COVID-19 leads to greater financial and clinical burden than for their counterparts, persons without diabetes, including perhaps most significantly, higher death rates.

Quality of life and persistence of COVID-19 symptoms 90 days after hospital discharge

OBJECTIVE

We aimed to describe the persistence of symptoms in coronavirus disease 2019 (COVID-19) and quality of life (QoL) among patients 90 days after their discharge from the hospital for infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and to determine differences in QoL domains concerning the absence or presence of persistent symptoms.

METHODS

To measure QoL, we used a validated Spanish version of the 36-item Short Form Health Survey (SF-36).

RESULTS

We included 141 patients. Ninety days after discharge, COVID-19 symptoms persisted in 107 patients (75.9%), with fatigue (55.3%) and joint pain (46.8%) being the most frequent. According to the SF-36, the role-physical score was the dimension with the lowest values (median score, 25; interquartile range, 0-75). Patients with joint pain, fatigue, and dyspnea had lower scores than patients without those symptoms, with 10 of the 13 evaluated SF-36 scales showing lower levels.

CONCLUSION

Ninety days after hospital discharge from COVID-19 reference centers, most patients had persistent symptoms and had lower SF-36 scores than patients without symptoms. It is important to follow-up patients discharged from the hospital after SARS-CoV-2 infection, ideally through a post-COVID-19 health care clinic and rehabilitation program, to improve QoL in these patients.

The Role of Imaging in the Detection of Non-COVID-19 Pathologies during the Massive Screening of the First Pandemic Wave

During the COVID-19 pandemic induced by the SARS-CoV-2, numerous chest scans were carried out in order to establish the diagnosis, quantify the extension of lesions but also identify the occurrence of potential pulmonary embolisms. In this perspective, the performed chest scans provided a varied database for a retrospective analysis of non-COVID-19 chest pathologies discovered de novo. The fortuitous discovery of de novo non-COVID-19 lesions was generally not detected by the automated systems for COVID-19 pneumonia developed in parallel during the pandemic and was thus identified on chest CT by the radiologist. The objective is to use the study of the occurrence of non-COVID-19-related chest abnormalities (known and unknown) in a large cohort of patients having suffered from confirmed COVID-19 infection and statistically correlate the clinical data and the occurrence of these abnormalities in order to assess the potential of increased early detection of lesions/alterations. This study was performed on a group of 362 COVID-19-positive patients who were prescribed a CT scan in order to diagnose and predict COVID-19-associated lung disease. Statistical analysis using mean, standard deviation (SD) or median and interquartile range (IQR), logistic regression models and linear regression models were used for data analysis. Results were considered significant at the 5% critical level (p < 0.05). These de novo non-COVID-19 thoracic lesions detected on chest CT showed a significant prevalence in cardiovascular pathologies, with calcifying atheromatous anomalies approaching nearly 35.4% in patients over 65 years of age. The detection of non-COVID-19 pathologies was mostly already known, except for suspicious nodule, thyroid goiter and the ascending thoracic aortic aneurysm. The presence of vertebral compression or signs of pulmonary fibrosis has shown a significant impact on inpatient length of stay. The characteristics of the patients in this sample, both from a demographic and a tomodensitometric point of view on non-COVID-19 pathologies, influenced the length of hospital stay as well as the risk of intra-hospital death. This retrospective study showed that the potential importance of the detection of these non-COVID-19 lesions by the radiologist was essential in the management and the intra-hospital course of the patients.

Mortality in People with Type 2 Diabetes Following SARS-CoV-2 Infection: A Population Level Analysis of Potential Risk Factors

INTRODUCTION

Research is ongoing to increase our understanding of how much a previous diagnosis of type 2 diabetes mellitus (T2DM) affects someone's risk of becoming seriously unwell following a COVID-19 infection. In this study we set out to determine the relative likelihood of death following COVID-19 infection in people with T2DM when compared to those without T2DM. This was conducted as an urban population study and based in the UK.

METHODS

Analysis of electronic health record data was performed relating to people living in the Greater Manchester conurbation (population 2.82 million) who had a recorded diagnosis of T2DM and subsequent COVID-19 confirmed infection. Each individual with T2DM (n = 13,807) was matched with three COVID-19-infected non-diabetes controls (n = 39,583). Data were extracted from the Greater Manchester Care Record (GMCR) database for the period 1 January 2020 to 30 June 2021. Social disadvantage was assessed through Townsend scores. Death rates were compared in people with T2DM to their respective non-diabetes controls; potential predictive factors influencing the relative likelihood of admission were ascertained using univariable and multivariable logistic regression.

RESULTS

For individuals with T2DM, their mortality rate after a COVID-19 positive test was 7.7% vs 6.0% in matched controls; the relative risk (RR) of death was 1.28. From univariate analysis performed within the group of individuals with T2DM, the likelihood of death following a COVID-19 recorded infection was lower in people taking metformin, a sodium-glucose cotransporter 2 inhibitor (SGLT2i) or a glucagon-like peptide 1 (GLP-1) agonist. Estimated glomerular filtration rate (eGFR) and hypertension were associated with increased mortality and had odds ratios of 0.96 (95% confidence interval 0.96-0.97) and 1.92 (95% confidence interval 1.68-2.20), respectively. Likelihood of death following a COVID-19 infection was also higher in those people with a diagnosis of chronic obstructive pulmonary disease (COPD) or severe enduring mental illness but not with asthma, and in people taking aspirin/clopidogrel/insulin. Smoking in people with T2DM significantly increased mortality rate (odds ratio of 1.46; 95% confidence interval 1.29-1.65). In a combined analysis of patients with T2DM and controls, multiple regression modelling indicated that the factors independently relating to a higher likelihood of death (accounting for 26% of variance) were T2DM, age, male gender and social deprivation (higher Townsend score).

CONCLUSION

Following confirmed infection with COVID-19 a number of factors are associated with mortality in individuals with T2DM. Prescription of metformin, SGLT2is or GLP-1 agonists and non-smoking status appeared to be associated with a reduced the risk of death for people with T2DM. Age, male sex and social disadvantage are associated with an increased risk of death.

The Risk Factors Potentially Influencing Hospital Admission in People with Diabetes, Following SARS-CoV-2 Infection: A Population-Level Analysis

INTRODUCTION

Since early 2020 the whole world has been challenged by the SARS-CoV-2 virus and the associated global pandemic (Covid-19). People with diabetes are particularly at high risk of becoming seriously unwell after contracting this virus.

METHODS

This population-based study included people living in the Greater Manchester conurbation who had a recorded diagnosis of type 1 diabetes mellitus (T1DM) or type 2 diabetes mellitus (T2DM) and subsequent Covid-19 infection. Each individual with T1DM (n = 862) or T2DM (n = 13,225) was matched with three Covid-19-infected non-diabetes controls.

RESULTS

For individuals with T1DM, hospital admission rate in the first 28 days after a positive Covid-19 test was 10% vs 4.7% in age/gender-matched controls [relative risk (RR) 2.1]. For individuals with T2DM, hospital admission rate after a positive Covid-19 test was 16.3% vs 11.6% in age/gender-matched controls (RR 1.4). The average Townsend score was higher in T2DM (1.8) vs matched controls (0.4), with a higher proportion of people with T2DM observed in the top two quintiles of greatest disadvantage (p < 0.001). For Covid-19-infected individuals with T1DM, factors influencing admission likelihood included age, body mass index (BMI), hypertension, HbA1c, low HDL-cholesterol, lower estimated glomerular filtration rate (eGFR), chronic obstructive pulmonary disease (COPD) and being of African/mixed ethnicity. In Covid-19-infected individuals with T2DM, factors related to a higher admission rate included age, Townsend index, comorbidity with COPD/asthma and severe mental illness (SMI), lower eGFR. Metformin prescription lowered the likelihood. For multivariate analysis in combined individuals with T2DM/controls, factors relating to higher likelihood of admission were having T2DM/age/male gender/diagnosed COPD/diagnosed hypertension/social deprivation (higher Townsend index) and non-white ethnicity (all groups).

CONCLUSION

In a UK population we have confirmed a significantly higher likelihood of admission in people with diabetes following Covid-19 infection. A number of factors mediate that increased likelihood of hospital admission. For T2DM, the majority of factors related to increased admission rate are common to the general population but more prevalent in T2DM. There was a protective effect of metformin in people with T2DM.

Breakdown of Diabetic Foot Ulcer Care during the First Year of the Pandemic in Poland: A Retrospective National Cohort Study

The COVID-19 pandemic revealed a breakdown of the system of DFU patient care. This retrospective national cohort study analyses the epidemiological status of DFU patients in relation to urgent and elective hospitalizations, amputation rates, and deaths in Poland from 2017 to 2019, and during 2020 when the COVID-19 pandemic began. The data were obtained from national medical records gathered by the National Health Fund (NHF). Discharge diagnoses were categorized according to ICD-10 and ICD-9 codes. Analysis of the data showed a statistically significant decrease in elective hospital admissions (from 29.6% to 26.3%, p = 0.001). There was a decrease in the percentage of hospitalizations related to limb-salvage procedures (from 79.4% to 71.3%, p = 0.001). The opposite tendency was observed among urgent hospital admissions (from 67.0% to 73.2%, p = 0.01), which was related to a significant increase in the number of minor amputations (from 3146 to 4269, p = 0.017). This rise was in parallel with the increase in the percentage of patients who died during hospitalization due to DFU (from 3.9% to 4.8%, p = 0.03). The number of deaths has not changed significantly (from 590.7 to 668.0, p = 0.26). The results of the conducted analyses confirm the negative tendencies in the medical care of patients with DFU during the first year of the pandemic in Poland. Changes in therapy schemes and stronger patient support following this period are necessary to avoid further complications in patients with DFU.

COVID-19 Adaptive Interventions: Implications for Wellbeing and Quality-of-Life

Social bonds may assist in cultivating a more positive attitude to life through commonly shared meanings about the COVID-19 pandemic. The key challenge, however, is how to foster social bonds meeting the changing demands in a post pandemic world. Yet, it is in the middle of a crisis that the conversation needs to start about how to strategically plan for the recovery. This is important not only in the current pandemic, but also in a post pandemic world. Reinforcing or fostering new social bonds is likely to bring positive experiences. The latter is central to human health and wellbeing, and has potential to contribute greatly in enhancing people's quality of life. In an attempt to foster place social bonding in the COVID-19 pandemic and beyond to subsequently contribute to wellbeing, this paper develops and proposes a new conceptual framework suggesting the need for adaptive social bonding interventions in the SARS-CoV-2 pandemic. This is an essential measure to manage the significant impacts on our global health services due to a decline in people's mental health in addition to COVID-19 physical impacts. The paper discusses how promoting adaptive social bonding interventions (psycho-socio, digital and nature social bonding) can make people more resilient. It further discusses how they can be empowered psychologically, socially, and emotionally in the current challenging times. The conceptual framework posits that social bonding interventions can assist in maintaining better mental, physical, emotional, and spiritual wellbeing and discusses how these wellbeing outcomes may also be experienced post the pandemic. This has important benefits and is of relevance to governments, policy makers and healthcare professionals in delivering better health care and equipping people with coping mechanisms both throughout the pandemic and in the long run.

Does coronavirus disease 2019 affect body mass index of children and adolescents who visited a growth clinic in South Korea?: a single-center study

PURPOSE

This study investigated the impact of coronavirus disease 2019 (COVID-19) on body mass index (BMI) of children and adolescents.

METHODS

From May to July 2020, the obesity rate of children and adolescents was compared retrospectively to the corresponding rate in the same period in 2019. The change in height, weight, and BMI of the girls who received a gonadotropin releasing hormone agonist (GnRHa) for precocious puberty (n=53) and the controls (n=31) who visited a growth clinic for early breast budding but were not treated with GnRHa in the first half of 2020 were compared to the corresponding change in the first half of 2019 using a paired t-test.

RESULTS

The rate of overweight or obesity in new outpatients (n=113, 83 girls, 30 boys) who visited growth clinics from May to July 2019 was 25.3% for girls and 23.3% for boys. The corresponding rate for the same period in 2020 (n=201, 153 girls, 48 boys) was 31.4% for girls and 45.8% for boys. There was a significant increase in the rate of overweight or obesity. The BMI of the GnRHa treatment group increased significantly from May to July 2019 than during the same period in 2020 (P<0.01). There was no significant difference in BMI between those periods in the control group.

CONCLUSION

During the social distancing period, the incidence of obesity was higher in boys than in girls. The obesity rate in girls who visited the growth clinic for early breast budding during routine follow-ups did not increase.

Prevalence of testing and coronavirus-19 among nurses in the pandemic

ABSTRACT Objective: To determine the prevalence of testing and COVID-19 among nurses during the pandemic in the State of Ceará. Method: A cross-sectional study with 379 nurses, through a network sampling technique, using a sociodemographic, labor, and clinical questionnaire. The study performed a descriptive statistics, univariate and multivariate logistic regression analysis. Results: The prevalence of testing and COVID-19 were, respectively, 63.3% and 25.0%. The most common symptoms were anosmia, ageusia, and myalgia. There was inadequate use of personal protective equipment due to material shortage. The odds ratio for COVID-19 was higher in those with children, people with diabetes, from the capital, with more than two jobs, in hospital and emergency room, and from the frontline. In the multivariate logistic regression, nurses with children (p=0.011), diabetics (p=0.018) and frontline (p<0.001) had more chances for COVID-19. Conclusion: Expanded testing, ongoing in-service education, and adequate personal protective equipment are needed to improve nurses’ work.

Impact of diabetes on the severity of COVID-19 infection in pregnant women - A single-center descriptive study

BACKGROUND AND AIMS

Pregnant women have significant morbidity and mortality due to COVID-19 infection. Pregnancy and diabetes are known risk factors for severe COVID 19 infection. Understanding the interactions between COVID-19 and diabetes in pregnancy is crucial in developing appropriate therapeutic approaches. India, like many other countries, has a very high prevalence of diabetes and COVID-19 infected cases. Such studies are minimal worldwide and none from India to the best of our knowledge.

MATERIALS AND METHODS

We did a retrospective cross-sectional study. 856 COVID-19 infected pregnant women were included in the study. We estimated the impact of diabetes on the severity of COVID-19 infected pregnant women and compared the outcomes with the non-diabetic group.

RESULTS

Prevalence of diabetes in pregnancy in the present study was 15.43%(n = 132/856). Prevalence of diabetes in non-severe infection was 14%(n = 115/818), severe infection was 44.73%(n = 17/38), and in maternal deaths was 75% (n = 6/8). The age-adjusted odds ratio for diabetes for severe infection was 4.492 (95% CI = 2.277-8.865, p < 0.001). COVID-19 infected pregnant women with diabetes were at higher risk for Cesarean section (78.3%) and ICU admission for newborns (14.81%) CONCLUSION: Diabetes in pregnant women is strongly associated with the severity of COVID-19 infection. The prevalence of diabetes in pregnancy increases as the severity of COVID-19 infection increases. Diabetes is associated with more adverse outcomes in mothers and newborns. It is necessary to identify pregnant women with diabetes and prioritize them in public health interventions like vaccination.

Endocrine risk factors for COVID-19 in context of aging

Aged people are the most susceptible group to COVID-19 infection. Immunosenescence characterized by impairment of immune function with inflamm-aging contributes to pathophysiological alterations, among which endocrine and metabolic diseases are not exception. Diabetes, obesity along with impairment of disorders of thyroid functions are the most frequent ones, the common feature of which is failure of immune system including autoimmune processes. In the minireview we discussed how COVID-19 and aging impact innate and adaptive immunity, diabetes and selected neuroendocrine processes. Mentioned is also beneficial effect of vitamin D for attenuation of these diseases and related epigenetic issues. Particular attention is devoted to the role of ACE2 protein in the light of its intimate link with renin-angiotensin regulating system.

Association between hyperglycemia treatment and mortality in patients with diabetes and COVID-19 in a Peruvian hospital: A retrospective cohort study

•

Very limited information about inpatient glycemic control or anti-hyperglycemic treatment strategies is available from low- and middle-income countries, such as Peru.

•

We observed a high mortality (39,1%) among patients with diabetes and COVID-19 in a Peruvian hospital. After admission, sliding scale insulin therapy was the most common treatment approach for hospitalized patients with diabetes and COVID-19.

•

Early and continuous use of sliding scale insulin alone was associated with higher mortality compared to fixed-dose insulin regimens.

•

In the context of COVID-19 pandemic, the use of the sliding scale insulin alone is frequent and its early and continuous use may be associated with higher in-hospital mortality, its use should be discouraged. Fixed-dose insulin is recommended, after an individualized evaluation.

Objective

To evaluate the association between hyperglycemia treatment and mortality in patients with diabetes and COVID-19 in a Peruvian hospital.

Methods

A retrospective cohort study was conducted between March and July 2020. Individual-level data were extracted from an implemented virtual platform. We included patients with type 2 diabetes hospitalized with COVID-19. The assessed outcome was in-hospital mortality. The Independent variable of interest was hyperglycemic treatment. We used Poisson regressions with robust variance to obtain crude and adjusted relative risks (RR) and their 95% confidence intervals (95% CI).

Results

Out of 1635 patients hospitalized for COVID-19 during the study period, 248 patients with diabetes mellitus were included. The majority were men (66.9%), the median age was 62 years. Ninety-seven patients died in the hospital (39.1%). The median glycemia on admission was 222.5 mg/dL. At 48 h after hospital admission, 125 patients (50.4%) received sliding scale insulin alone (SSI), 46 (18.5%) received a fixed-dose insulin regimen. In the adjusted analysis, the group with SSI at 48 h of hospitalization had higher mortality than those with fixed-dose insulin (adjusted RR: 1.69; 95% CI: 1.01 – 2.83), and those and who continued with SSI in the following days had higher mortality compared to the group that switched to fixed-dose insulin (adjusted RR: 1.64; 95% CI: 1.17 – 2.32).

Conclusion

Among assessed patients with diabetes and COVID-19, more than a third died during hospitalization. Early and continuous use of the sliding scale was associated with higher mortality compared to fixed-dose insulin regimens.

Effects of SARS-CoV-2 pandemic on follow-up and pharmacological treatment of chronic diseases in undocumented migrants

Background

All over the world, the COVID-19 pandemic, not unlikely other epidemics, has hit harder people in low socioeconomic conditions.

In Western countries, undocumented migrants are a growing component of this disadvantaged segment of the population.

Their health conditions are frequently burdened by a number of chronic conditions, and they experience many difficulties in accessing public health services. Frequently, the only medical assistance they can get is provided by non-governmental organisations.

Methods

We studied the medical records (including pharmacological treatments) of all patients attending the outpatient clinics of Opera San Francesco (OSF; a big charity in Milano, Italy), in the first 5 months of 2020. These comprise the outbreak of the pandemic and the lockdown period. The 1914 patients (1814 undocumented migrants and 100 Italians) seen during the lockdown were compared with those seen in the same period of 2019 and with those seen in the preceding months of 2020. We especially focused on three chronic conditions: cardiovascular diseases, diabetes and psychiatric disorders.

Results

The number of consultations during the first 5 months of 2020 was much smaller than that of the same period of 2019. During the lockdown, we found 4048 consultations for 1914 patients, while they were 8051 in the same period of 2019 and 5681 in the first 2 months of 2020.

The quantity of medicines dispensed by OSF showed a marked decrease in the period of the study and mainly during the lockdown.

The decrease in consultations and dispensation of medicines was most evident for psychiatric patients and almost not existent for patients with diabetes. Female patients suffered a more pronounced reduction.

Conclusions

Western countries need strategies to better assist the very poor during epidemics.

Differences among different groups of disadvantaged persons should be taken into account when designing recovery plans.

Coronavirus disease 19 and risk of hyperglycemia among Iraqi patients

A cross-sectional observational study was conducted on 213 patients with COVID-19 who did not have a clinical history of diabetes at hospital admission. One week after hospitalization, they were stratified by random blood glucose levels. It was found that 25.4, 22.5 and 52.1% of COVID-19 patients were classified as normoglycemia, prediabetes and diabetes, respectively. The study indicated that diabetes may be a risk factor for COVID-19 or the disease may be associated with an increased risk of developing diabetes.

Epidemiologic Characteristics of and Prognostic Factors for COVID-19 Among Hospitalized Patients: Updated Implications From Hubei Province, China

Introduction: The roles of some indicators in the prognosis of patients with coronavirus disease-19 (COVID-19) remain unclear and controversial. This study aimed to explore the epidemiologic characteristics of and prognostic factors for COVID-19 to provide updated recommendations for its prevention, diagnosis, and treatment.

Methods: For this retrospective study, demographic, epidemiologic, and clinical data were extracted from the medical records of patients admitted to the Maternal and Child Hospital of Hubei Province (Optical Valley) with COVID-19 between February 19, 2020, and March 19, 2020. The primary outcome was the prognosis that was determined at discharge as mentioned in the medical records. Descriptive statistics, univariate analyses, and stepwise logistic regression analysis were used for data analysis.

Results: Of the 1,765 patients included, 93.1% were cured and the mortality was 1.8%. Univariate analyses identified 63 factors significantly associated with COVID-19 prognosis. Logistic regression analysis revealed that a poorer prognosis was associated with undergoing resuscitation, complex disease manifestations, consultation with outside specialists, elevated basophil or lymphocyte counts, an albumin (ALB)/globulin (A/G) ratio > 2.4, and elevated levels of serum aspartate aminotransferase (AST) or creatinine. Patients had a better prognosis if the following conditions were met: dry cough reported as an initial symptom, fatigue as a clinical manifestation, and a diagnosis based on laboratory testing.

Conclusion: To prevent clinical deterioration, clinicians should provide special care to patients who underwent resuscitation, with a critical disease, or requiring consultation with outside specialists. Extra attention should be paid to patients with high basophil or lymphocyte counts, a high A/G ratio, and elevated AST or creatinine levels.

Association of diabetes with severity and mortality in hospitalized patients with COVID-19 in Wuhan, China: a single-centered, retrospective study

OBJECTIVE

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has spread worldwide. The aim this study was to investigate the association of diabetes with severity and mortality among hospitalized patients with COVID-19 in Wuhan, China.

METHODS

This retrospective, single-center case study enrolled a total of 564 patients diagnosed with COVID-19 at the Seventh Hospital of Wuhan City, between January 20 and March 15, 2020.

RESULTS

Among the 564 patients with confirmed COVID-19, 509 (85.1%) were discharged and 55 (9.8%) died. The median age was 59 years (range, 10-93 years). A total of 85 (15.1%) patients were diagnosed with diabetes on admission (median age, 65.0 [range, 34-91] years). Patients with diabetes had significantly higher proportions of critical cases (24 [28.2%] vs. 66 [13.8%]) and in-hospital mortality (17 [20%] vs. 38 [7.9%]). Moreover, patients with diabetes presented abnormal levels of multiple indicators concerning lymphopenia, inflammation, heart, liver, kidney, and lung function on admission, while diabetic patient group still display higher troponin T (TnT) levels when approaching discharge. The Kaplan-Meier survival curve indicated a trend toward poorer survival in diabetic patients compared to non-diabetic patients, also evidenced by abnormal laboratory biomarker changes regarding multiple system impairments among COVID-19 patients with diabetes with in-hospital death.

CONCLUSION

The detailed clinical investigation of 564 hospitalized patients with COVID-19 indicated a considerable association between diabetes and COVID-19 severity or mortality. Thus, more intensive treatment may be considered for COVID-19 patients with diabetes, especially regarding to cardiac injury.

The Omic Insights on Unfolding Saga of COVID-19

The year 2019 has seen an emergence of the novel coronavirus named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing coronavirus disease of 2019 (COVID-19). Since the onset of the pandemic, biological and interdisciplinary research is being carried out across the world at a rapid pace to beat the pandemic. There is an increased need to comprehensively understand various aspects of the virus from detection to treatment options including drugs and vaccines for effective global management of the disease. In this review, we summarize the salient findings pertaining to SARS-CoV-2 biology, including symptoms, hosts, epidemiology, SARS-CoV-2 genome, and its emerging variants, viral diagnostics, host-pathogen interactions, alternative antiviral strategies and application of machine learning heuristics and artificial intelligence for effective management of COVID-19 and future pandemics.

Over 60 years of age as an independent prognostic factor of in-hospital mortality among COVID-19 patients: a cohort study in an Iranian high-incidence area

Objectives

COVID-19 continues to cause devastation throughout the world. Various factors influence the perioperative course and prognosis of COVID-19. This study aims to collate the independent prognostic factors among hospitalised COVID-19 patients in east Iran.

Study design

In this cohort study, all patients with a confirmed diagnosis of COVID-19 between 19 February 2020 and 1 August 2020 who were admitted to nine public hospitals of South Khorasan province, Iran, were enrolled.

Methods

Univariate analysis (chi-square [χ²], and Mann–Whitney U test) and multiple logistic regression were performed.

Results

This study included 1290 participants; 676 patients (52.4%) were male. A total of 1189 (92.2%) recovered, and 101 (7.8%) died. The results show that in-hospital mortality increases with advanced age (the optimal cut-off point = 62 years). The following three variables were shown to have the most significant role in in-hospital mortality: age >60 years (odds ratio [OR] = 8.01, 95% confidence interval [CI] 4.8–13.35), shortness of breath (OR = 2.65, 95% CI: 1.4–69.17) and atypical radiological manifestations in a chest X-ray on admission (OR = 2.16, 95% CI: 1.3–28.64). In the univariate analysis, associated comorbidities, such as cardiovascular diseases, influenced the in-hospital mortality rate, while the same could not be replicated in the multiple variable analysis.

Conclusions

This study revealed the potential predictors of COVID-19 and highlighted the need to be cautious with advanced age and heightened clinical symptoms at the time of admission.

Evolution of the Use of Corticosteroids for the Treatment of Hospitalised COVID-19 Patients in Spain between March and November 2020: SEMI-COVID National Registry

OBJECTIVES

Since the results of the RECOVERY trial, WHO recommendations about the use of corticosteroids (CTs) in COVID-19 have changed. The aim of the study is to analyse the evolutive use of CTs in Spain during the pandemic to assess the potential influence of new recommendations.

MATERIAL AND METHODS

A retrospective, descriptive, and observational study was conducted on adults hospitalised due to COVID-19 in Spain who were included in the SEMI-COVID-19 Registry from March to November 2020.

RESULTS

CTs were used in 6053 (36.21%) of the included patients. The patients were older (mean (SD)) (69.6 (14.6) vs. 66.0 (16.8) years; p < 0.001), with hypertension (57.0% vs. 47.7%; p < 0.001), obesity (26.4% vs. 19.3%; p < 0.0001), and multimorbidity prevalence (20.6% vs. 16.1%; p < 0.001). These patients had higher values (mean (95% CI)) of C-reactive protein (CRP) (86 (32.7-160) vs. 49.3 (16-109) mg/dL; p < 0.001), ferritin (791 (393-1534) vs. 470 (236-996) µg/dL; p < 0.001), D dimer (750 (430-1400) vs. 617 (345-1180) µg/dL; p < 0.001), and lower Sp02/Fi02 (266 (91.1) vs. 301 (101); p < 0.001). Since June 2020, there was an increment in the use of CTs (March vs. September; p < 0.001). Overall, 20% did not receive steroids, and 40% received less than 200 mg accumulated prednisone equivalent dose (APED). Severe patients are treated with higher doses. The mortality benefit was observed in patients with oxygen saturation

CONCLUSIONS

Patients with greater comorbidity, severity, and inflammatory markers were those treated with CTs. In severe patients, there is a trend towards the use of higher doses. The mortality benefit was observed in patients with oxygen saturation Collapse

The frail world of haemodialysis patients in the COVID-19 pandemic era: a systematic scoping review

BACKGROUND

Patients undergoing in-centre haemodialysis (HD) are particularly exposed to the dire consequences of COVID-19. The present systematic scoping review aims to identify the extent, range, and nature of articles related to COVID-19 and maintenance HD: it reports specifically the prevalence of the COVID-19 pandemic in the HD population, implementation of strategies for the prevention, mitigation and containment of the COVID-19 pandemic in HD centres, demographic and clinical characteristics, and outcomes of the pediatric and adult HD patients.

METHODS

A multi-step systematic search of the literature in Pubmed, Scopus, Ovid Medline, Embase and Web of Science, published between December 1, 2019, and January 30, 2021 was performed. Two authors separately screened the titles and abstracts of the documents and ruled out irrelevant articles. A report of the papers that met inclusion criteria was performed; then, a descriptive analysis of the characteristics of the included articles and a narrative synthesis of the results were performed.

RESULTS

The review process ended with the inclusion of 145 articles. Most of them were based on single-centre experiences, which spontaneously developed best practices. Most studies were conducted in high-income countries (69.7%) and a part of them (9.6%) were not in English. Prevalence of COVID-19 among dialysis patients accounted for 0%-37.6%. Preventive measures were reported in 54% of the included articles, with particular emphasis on education, triage, hygiene, and containment measures. Patients experienced a heterogeneous spectrum of symptoms that led 35%-88.2% of them to hospital admission. Median and mean hospital length of stay ranged from 8 to 28.5 and 16.2 to 22 days, respectively. Admission to intensive care units varied widely across studies (from 2.6% to 70.5%) and was associated with high mortality (42.8%-100%). Overall, prognosis was poor in 0%-47% of the hospitalized patients.

CONCLUSIONS

This systematic scoping review provides an overview of the current knowledge on the impact of COVID-19 on the frail world of HD patients. Furthermore, it may help to implement the existing strategies of COVID-19 prevention and provide a list of unmet needs (safe transport, testing, shelter). Finally, it may be a stimulus for performing systematic reviews and meta-analyses which will form the basis for evidence-based guidelines.

Akt-independent effects of triciribine on ACE2 expression in human lung epithelial cells: Potential benefits in restricting SARS-CoV2 infection

The severe acute respiratory syndrome coronavirus 2 that causes coronavirus disease 2019 (COVID-19) binds to the angiotensin-converting enzyme 2 (ACE2) to gain cellular entry. Akt inhibitor triciribine (TCBN) has demonstrated promising results in promoting recovery from advanced-stage acute lung injury in preclinical studies. In the current study, we tested the direct effect of TCBN on ACE2 expression in human bronchial (H441) and lung alveolar (A549) epithelial cells. Treatment with TCBN resulted in the downregulation of both messenger RNA and protein levels of ACE2 in A549 cells. Since HMGB1 plays a vital role in the inflammatory response in COVID-19, and because hyperglycemia has been linked to increased COVID-19 infections, we determined if HMGB1 and hyperglycemia have any effect on ACE2 expression in lung epithelial cells and whether TCBN has any effect on reversing HMGB1- and hyperglycemia-induced ACE2 expression. We observed increased ACE2 expression with both HMGB1 and hyperglycemia treatment in A549 as well as H441 cells, which were blunted by TCBN treatment. Our findings from this study, combined with our previous reports on the potential benefits of TCBN in the treatment of acute lung injury, generate reasonable optimism on the potential utility of TCBN in the therapeutic management of patients with COVID-19.

Diabetes and COVID-19 in Congolese patients

Background

The global pandemic Coronavirus Disease 2019 (COVID-19) due to the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is reported to be potentially severe in patients with morbid conditions. One common reported comorbidities is diabetes. We aimed in this study to precise the clinical characteristics and outcomes in a series of congolese diabetic patients affected by COVID-19 infection.

Patients and methods

We retrospectely studied from 256 COVID-19 patients, a cohort of 30 persons with previously known diabetes. The glycaemia controls have been obtained by plasma glucose assay. All patients have been tested positive to SARS-CoV-2 by RT-PCR method.

Results

The COVID-19 diabetic patients represented 11,7% of all COVID-19 patients with confidence interval of 95% [7,77–15,65]. Older individuals and male sex were predominent. Dyspnea and sauration of oxygen < 90 were significatives and added risk factors were noted in 63.3% of patients, particulary hyperglycaemia with hypertension or obesity. The mortality rate at the percentage of 36.7% was more prevalent in patients with added comorbidities (30%) versus without comorbidities (6.7%).

Conclusion

Congolese COVID-19 diabetic patients of male sex and older age exhibiting arterial hypertension and obesity are the most exposed to severe COVID-19 and increasead mortality rate.

Study on acupuncture in the treatment of painful diabetic peripheral neuropathy based on rs-fMRI: a protocol for systematic review and meta-analysis

INTRODUCTION

Studies have shown that acupuncture has significant therapeutic effects on painful diabetic peripheral neuropathy (PDPN) yet the precise mechanism of action underpinning these effects remains controversial. Resting-state functional MRI (rs-fMRI) is an advanced imaging technique that can be used to monitor changes in the activity of the brain, particularly in PDPN. However, the data from several studies remain inconclusive and there is currently no systematic review and meta-analysis for the use of rs-fMRI in PDPN.

METHODS AND ANALYSIS

In this study, we will select all eligible studies published on or before 30 June 2021. Four English and four Chinese databases will be searched, specifically, PubMed, Embase, Web of Science, Cochrane Library, China National Knowledge Infrastructure, WanFang database, China Science Technology Journal Database (VIP) and China Doctor/Master Dissertations Full-text Database. Only clinical trials and the first cycle of a cross-over trial linked to acupuncture for PDPN will be included in the analysis. The main outcomes include the amplitude of low-frequency fluctuation, regional homogeneity, functional connectivity of the brain, bilateral superficial peroneal nerve sensory nerve conduction velocity, bilateral dorsal current perception threshold values and the degree of subjective pain. The secondary outcomes include biochemical indicators, the degree of depression and anxiety and changes in efficiency. The study selection, data extraction and risk of bias assessment will be performed by two investigators. For statistical analyses, Review Manager V.5.4 software will be used. If necessary, heterogeneity testing, data synthesis, and subgroup analysis will be performed.

ETHICS AND DISSEMINATION

Our systematic review and meta-analysis will be based on published literature for data extraction and will not include the use of individual patient data and so no ethical approval required.

Bidirectional Relationship between COVID-19 and Diabetes: Role of Renin-Angiotensin-Aldosterone System and Drugs Modulating It

Numerous reports have suggested that diabetic patients are at high risk for the development of severe symptoms of coronavirus disease-2019 (COVID-19). However, a few studies have recently proposed that the relationship between diabetes and COVID-19 is bidirectional, as severe acute respiratory syndrome-coronavirus-2 also has the capability to induce diabetes. Various mechanisms have been identified and proposed to be involved in this binary association. In this review, the importance and impact of renin-angiotensin-aldosterone system (RAAS) in this two-way association of COVID-19 and diabetes has been summarized. The role and effect of drugs modulating RAAS directly or indirectly has also been discussed, as they can majorly impact the course of treatment in such patients. Further reports and data can present a clear picture of RAAS and its modulators in restoring the balance of dysregulated RAAS in COVID-19.

Diabetic ketoacidosis drives COVID-19 related hospitalizations in children with type 1 diabetes

BACKGROUND

Diabetes is a risk factor for poor COVID-19 outcomes, but pediatric patients with type 1 diabetes are poorly represented in current studies.

METHODS

T1D Exchange coordinated a US type 1 diabetes COVID-19 registry. Forty-six diabetes centers submitted pediatric cases for patients with laboratory confirmed COVID-19. Associations between clinical factors and hospitalization were tested with Fisher's Exact Test. Logistic regression was used to calculate odds ratios for hospitalization.

RESULTS

Data from 266 patients with previously established type 1 diabetes aged <19 years with COVID-19 were reported. Diabetic ketoacidosis (DKA) was the most common adverse outcome (n = 44, 72% of hospitalized patients). There were four hospitalizations for severe hypoglycemia, three hospitalizations requiring respiratory support (one of whom was intubated and mechanically ventilated), one case of multisystem inflammatory syndrome in children, and 10 patients who were hospitalized for reasons unrelated to COVID-19 or diabetes. Hospitalized patients (n = 61) were more likely than nonhospitalized patients (n = 205) to have minority race/ethnicity (67% vs 39%, P < 0.001), public insurance (64% vs 41%, P < 0.001), higher A1c (11% [97 mmol/mol] vs 8.2% [66 mmol/mol], P < 0.001), and lower insulin pump and lower continuous glucose monitoring use (26% vs 54%, P < 0.001; 39% vs 75%, P < 0.001). Age and gender were not associated with risk of hospitalization. Higher A1c was significantly associated with hospitalization, with an odds ratio of 1.56 (1.34-1.84) after adjusting for age, gender, insurance, and race/ethnicity.

CONCLUSIONS

Higher A1c remained the only predictor for hospitalization with COVID-19. Diabetic ketoacidosis is the primary concern among this group.

Highly sensitive non-enzymatic electrochemical glucose sensor surpassing water oxidation interference

An electrochemical non-enzymatic sensor based on a NiVP/Pi material was developed for the selective and sensitive determination of glucose. The novel sensor showed a high sensitivity of 6.04 mA μM-1 cm-2 with a lowest detection limit of 3.7 nM in a wide detection range of 100 nM-10 mM. The proposed sensor exhibited a superior selectivity without any interference from the oxygen evolution reaction during glucose sensing. We also found that this glucose sensor showed negligible interference from various interferents, such as ascorbic acid, uric acid, dopamine and sodium chloride. Additionally, a novel flexible sensor was developed by coating the NiVP/Pi over Whatman filter paper, which exhibited two linear ranges of 100 nM to 1 μM and 100 μM to 10 mM with an ultra-sensitivity of 1.130 mA μM-1 cm-2 and 0.746 mA μM-1 cm-2, respectively, in 0.1 M NaOH. The proposed sensor was tested with human blood serum samples demonstrating its practical application. Our findings provide a new route by fine tuning the composition of nickel and vanadium that sheds new light on better understanding the processes. This NiVP/Pi-based sensor offers a new approach towards the electrochemical detection of glucose, enabling glucose monitoring in a convenient way.

Profile and prognosis of patients hospitalized for COVID-19 virus infection with and without diabetes - An observational study from South India

BACKGROUND AND AIMS

We studied the profile and outcome of patients hospitalized for coronavirus disease-19 (COVID-19) infection with and without type 2 diabetes (T2DM).

METHODS

In this observational study, clinical details of patients with COVID-19, identified by Reverse Transcription - Polymerase Chain Reaction admitted to 4 hospitals in Chennai, Tamil Nadu, India were collected from May to November 2020. A total of 845 (n = 423 with diabetes, n = 422 without diabetes) were selected for the analysis. Clinical details, biochemical and radiological investigations, diabetes treatment, intensive care, mortality and other adverse outcomes were recorded. Patients with clinical history of T2DM, glycosylated haemoglobin (HbA1c) of ≥6.5% (48 mmol/mol) and/or random blood glucose ≥200 mg/dl (11.1 mmol/l) were included. Statistical analyses were done using chi-square or 't' test and multiple logistic regression analysis.

RESULTS

At admission, patients with T2DM were older (p < 0.0001), had higher co-morbidities such as coronary artery disease (p = 0.02), hypertension (p < 0.0001), hypothyroidism (p = 0.03) and renal disorders (p = 0.01) than non-diabetes persons. Requirement for intensive care was higher among them. Acute renal injury or failure, pneumonia and myocardial infarction developed in higher percentage of T2DM. Mortality was significantly higher in T2DM (10.2% vs 5.9%, p = 0.02). However, in the multiple logistic regression analysis, only age (p < 0.0001) and renal disorders (p = 0.002) were significantly associated with mortality.

CONCLUSION

Our study showed that mortality was associated with higher age and renal disorders but did not show an association with diabetes, among patients hospitalized for COVID-19 infection.

General practice attendances among patients attending a post-COVID-19 clinic: a pilot study

Background

About 10–35% of people with COVID-19 need medical care within 3 weeks of infection. However, the prevalence of ongoing care needs among those experiencing severe COVID-19 illness is unclear.

Aim

This pilot study aimed to address this knowledge gap by examining GP attendance trends among patients attending a post-COVID-19 hospital follow-up clinic, 3–6 months after an initial clinic visit.

Design & setting

Data were collected from adult patients attending a post-COVID-19 follow-up clinic at the Mater Misericordiae University Hospital (MMUH), Dublin, Ireland.

Method

Participants completed questionnaires outlining their demographics; medical histories; emergency hospital admissions and readmissions where applicable; and, where relevant, GP attendances following hospital discharge. Analyses were conducted using descriptive and inferential statistics.

Results

Participants’ (n = 153) median age was 43.5 years (interquartile range [IQR] = 30.9–52.1 years). There were 105 females (68.6%, 95% confidence interval [CI] = 61.3% to 75.9%). Various medical histories were reported among participants. Sixty-seven (43.2%, 95% CI = 35.9% to 51.6%) received emergency COVID-19 hospital care. Older adults, males, intensive care unit [ICU] admissions, and readmissions were common among hospital attendees. Of the hospital attendees, 16 (24%, 95% CI = 13.7% to 34.2%) attended GPs within 7 days of hospital discharge, and 26 (39%, 95% CI = 27.3% to 50.7%) within 30 days. Older adults, people with pre-existing medical conditions, and individuals admitted to ICU and/or readmitted to hospital were common among general practice attendees.

Conclusion

Persistent health issues appear to be common among patients with severe COVID-19, particularly those who are older adults, have pre-existing health problems, and who had been in ICU and/or readmission care. Larger scale studies of ongoing COVID-19 care needs in primary care and general practice are required.

Pediatric Endocrinology of Post-Pandemic Era

The COVID-19 pandemic has brought about significant changes in the global health and medical environment. In order to prevent viral transmission, governments implemented strong social distancing, even lockdowns. The closure of schools has reduced physical activity among children and adolescents. Children, especially those with chronic diseases, are often reluctant to visit or even give up visiting hospitals, resulting in delayed diagnosis or missing the right timing for treatment. New guidelines are needed for the management of patients with endocrine diseases such as diabetes or thyroid disease, as well as children with chronic diseases who need regular clinical monitoring. Therefore, it is necessary to analyze the previous research on pediatric endocrinology reported during COVID-19, guide the direction for future research, and establish guidelines to care for pediatric patients with endocrine diseases in the post-pandemic era.

Risk Factors for Mortality in COVID-19 Hospitalized Patients in Piedmont, Italy: Results from the Multicenter, Regional, CORACLE Registry

BACKGROUND

CORACLE is a retrospective and prospective, regional multicenter registry, developed to evaluate risk factors for mortality in a cohort of patients admitted with SARS-CoV-2 infection within non-intensive wards.

METHODS

The primary objective was to estimate the role of several prognostic factors on hospital mortality in terms of adjusted Odds Ratios (aOR) with multivariable logistic regression models.

RESULTS

A total of 1538 patients were enrolled; 42% were female, and 58% were >70 years old. Deceased patients were 422 (27%), with a median age of 83 years (IQR (Inter Quartile Range) 76-87). Older age at admission (aOR 1.07 per year, 95%CI 1.06-1.09), diabetes (1.41, 1.02-1.94), cardiovascular disease (1.79, 1.31-2.44), immunosuppression (1.65, 1.04-2.62), estimated glomerular filtration rate (eGFR) <30 mL/min/1.73 m2 (3.53, 2.26-5.51), higher C-reactive protein values and a decreased PaO2/FiO2 ratio at admission were associated with a higher risk of hospital mortality. Amongst patients still alive on day 7, only hydroxychloroquine (HCQ) treatment was associated with reduced mortality (0.57, 0.36-0.90).

CONCLUSIONS

Several risk factors were associated with mortality in SARS-CoV-2 positive patients. Although HCQ seems to be the only factor significantly associated with reduced mortality, this result is in contrast with evidence from randomized studies. These results should be interpreted in light of the study limitations.

Thymulin and peroxiredoxin 6 have protective effects against streptozotocin-induced type 1 diabetes in mice

Protective effects of peroxiredoxin 6 (PRDX6) in RIN-m5F β-cells and of thymulin in mice with alloxan-induced diabetes were recently reported. The present work was aimed at studying the efficiency of thymulin and PRDX6 in a type 1 diabetes mellitus model induced by streptozotocin in mice. Effects of prolonged treatment with PRDX6 or thymic peptide thymulin on diabetes development were evaluated. We assessed the effects of the drugs on the physiological status of diabetic mice by measuring blood glucose, body weight, and cell counts in several organs, as well as effects of thymulin and PRDX6 on the immune status of diabetic mice measuring concentrations of pro-inflammatory cytokines in blood plasma (TNF-α, interleukin-5 and 17, and interferon-γ), activity of NF-κB and JNK pathways, and Hsp90α expression in immune cells. Both thymulin and PRDX6 reduced the physiological impairments in diabetic mice at various levels. Thymulin and PRDX6 provide beneficial effects in the model of diabetes via very different mechanisms. Taken together, the results of our study indicated that the thymic peptide and the antioxidant enzyme have anti-inflammatory functions. As increasing evidences show diabetes mellitus as a distinct comorbidity leading to acute respiratory distress syndrome and increased mortality in patients with COVID-19 having cytokine storm, thymulin, and PRDX6 might serve as a supporting anti-inflammatory treatment in the therapy of COVID 19 in diabetic patients.

The role of concomitant cardiovascular diseases and cardiac biomarkers for predicting mortality in critical COVID-19 patients

BACKGROUND

to identify the potential cardiovascular risk factors associated with mortality in hospitalised COVID-19 patients.

METHODS

All consecutive patients admitted to intensive care unit (ICU) of our institute for COVID-19 from 1 April 2020 to 20 May 2020 were included. Patient characteristics including complete medical history and comorbid diseases, admission and 7th day blood test results and clinical characteristics were compared between survivors and non-survivors.

RESULTS

There were no significant difference between survivors and non-survivors regarding age, gender, and pre-existing coronary artery disease, hypertension, diabetes, heart failure, coronary artery bypass grafting surgery, percutaneous coronary intervention and coronary stenting. Admission D-dimer and NT-proBNP levels of non-survivors were significantly higher than survivors. CRP, procalcitonin, creatine kinase (CK) and troponin I levels on 7th day of admission were significantly higher in non-survivors compared to survivors. In addition, both admission and 7th day lymphocyte count were lower in non-survivors compared to that of the survivors. CRP declined from admission to 7th day of hospitalisation in survivors, whereas a median 6.75 mg/L increase was observed in non survivors. The peak and minimum CRP, procalcitonin and levels were significantly higher in non-survivors than survivors. The peak NT-proBNP level of non-survivors was also significantly higher than that of the survivors. Intubation, lower GFR values and higher NT-proBNP values were predictive for death.

CONCLUSION

The prothrombotic coagulopathy mediated by the endothelial interaction with SARS-CoV-2 may also have role in unfavourable prognosis in COVID-19. These readily available biomarkers might be useful in risk stratification of COVID-19 cases.

Intestinal SGLT1 as a therapeutic target in COVID-19-related diabetes: A "two-edged sword" hypothesis

Emerging data are linking coronavirus disease 2019 (COVID‐19) with an increased risk of developing new‐onset diabetes. The gut has been so far out of the frame of the discussion on the pathophysiology of COVID‐19‐induced diabetes, with the pancreas, liver, and adipose tissue being under the spotlight of medical research. Sodium‐glucose co‐transporters (SGLT) 1 represent important regulators of glucose absorption, expressed in the small intestine where they mediate almost all sodium‐dependent glucose uptake. Similar to what happens in diabetes and other viral infections, SGLT1 upregulation could result in increased intestinal glucose absorption and subsequently promote the development of hyperglycaemia in COVID‐19. Considering the above, the question whether dual SGLT (1 and 2) inhibition could contribute to improved outcomes in such cases sounds challenging, deserving further evaluation. Future studies need to clarify whether putative benefits of dual SGLT inhibition in COVID‐19 outweigh potential risks, particularly with respect to drug‐induced euglycaemic diabetic ketoacidosis, gastrointestinal side effects, and compromised host response to pathogens.

Management of Diabetes During a Dual Pandemic

The dual pandemics of coronavirus disease-19 (COVID-19) and diabetes among patients are associated with 2- to 3-times higher intensive care admissions and higher mortality rates. Whether sheltering at home, quarantined with a positive COVID-19 test, or hospitalized, the person living with diabetes needs special considerations for successful management. Having diabetes and being COVID-19-positive increases the risk of poor outcomes and death. Providers need to give anticipatory pharmacologic guidance to patients with diabetes during COVID-19 lockdown. Patients with diabetes need to be more observant than others and to use self-protective actions. This review (1) discusses the clinical observations of COVID-19, diabetes and underlying mechanisms, (2) describes special considerations in caring for patients with diabetes in a COVID-19 environment, and (3) reviews clinical implications for the health care provider. This review highlights current evidenced-based knowledge. Additional research regarding clinical management is warranted.

The interval between onset and admission predicts disease progression in COVID-19 patients

Background

The prognostic role of the interval between disease onset and hospital admission (O-A interval) was undetermined in patients with the coronavirus disease 2019 (COVID-19).

Methods

A total of 205 laboratory-confirmed inpatients admitted to Hankou hospital of Wuhan from January 11 to March 8, 2020 were consecutively included in this retrospective observational study. Demographic data, medical history, laboratory testing results were collected from medical records. Univariate and multivariate logistic regression models were used to evaluate the prognostic effect of the O-A interval (≤7 versus >7 days) on disease progression in mild-to-moderate patients. For severe-to-critical patients, the in-hospital mortality and the length of hospital stay were compared between the O-A interval subgroups using log-rank test and Mann-Whitney U test, respectively.

Results

Mild-to-moderate patients with a short O-A interval (≤7 days) are more likely to deteriorate to severe-to-critical stage compared to those with a long O-A interval (>7 days) [unadjusted odds ratio =2.93, 95% confidence interval (CI), 1.32–6.55; adjusted odds ratio =3.44, 95% CI, 1.20–9.83]. No association was identified between the O-A interval and the mortality or the length of hospital stay of severe-to-critical patients.

Conclusions

The O-A interval has predictive values for the disease progression in mild-to-moderate COVID-19 patients. Under circumstances of the specific health system in Wuhan, China, the spontaneous healthcare-seeking behavior is usually determined by patients’ own heath conditions. Hence, the O-A interval can be reflective of the natural course of COVID-19 to some extent. However, our findings should be validated further in other cohorts and in other health systems.

Tracheostomy in the COVID19 Patients: Our Experience in 12 Cases

The incidence of tracheostomy has been significantly increased with the increase of patients admitted to the intensive care units. Looking into the literature, there have been various protocols proposed in the past for tracheostomy in COVID 19 patients. In the present case series, we have presented our experience of surgical tracheostomy in COVID 19 patients. It is a retrospective case series consisting of 12 COVID 19 patients who underwent tracheostomy from April 2020 to October 2020. We have discussed the tracheostomy in COVID 19 patients with references to their respective indication, location, the procedure, postoperative care and clinical outcomes. Of 12 patients, 6 were operated in the COVID ICU and 6 were operated in the COVID OT. The average duration of the intubation was 4 days (range 3–7 days). The average period of weaning was found to be 65 h (range 48 h 80 h). Of 4 patients associated with comorbidities, two had died 48 h after the surgery. The Primary indication of the tracheostomy can be made flexible based on the infrastructure of the hospital to accommodate increased patient load in a developing country like India. The location and surgical approach does not significantly affect the clinical outcomes of tracheostomy, and it can be safely performed in ICU/OT with adequate ventilation. Irrespective of the COVID status of the patients, Personal Protective Equipment (PPE) can ensure adequate protection to the health care personals preventing the spread of infection.
