Impact of COVID-19 pandemic on medicine supply chain for patients with chronic diseases: Experiences of the community pharmacists

Problem considered

Coronavirus disease(COVID-19) outbroke towards the end of December 2019 in China, soon it started spreading rapidly to various countries leading to an outburst of pandemic. Due to the restrictions imposed to control the spread of the infection, globally the manufacturing, import and export of medicine and the healthcare services to patients with chronic illness had been affected. This study aimed to explore the perspectives of the pharmacists on the medicine supply chain for patients with chronic diseases during COVID-19 pandemic in India.

Methods

This study is a prospective, qualitative research involving telephonic, semi-structured in-depth interviews. An interview guide for pharmacists was prepared and validated using "Interview Protocol Refinement" method. Purposive sampling method was used to recruit the pharmacists; a telephonic oral consent was obtained. The interview session was audio recorded and the recordings were transcribed verbatim. Further, transcripts were validated and later analysed using NVivo software.

Results

A total of 8 participants were interviewed during our study. Thematic analysis of the transcripts resulted in seven main themes. The study showed that there was deficiency in medicine supply during the COVID-19 pandemic and the pharmacists faced several challenges in procuring and storing the medication, arranging for unavailable medicines, medication dispensing and provision of the services such as medicine delivery, patient counselling. There was also scarcity of manpower leading to extra workload and working overtime.

Conclusion

Uninterrupted supply of essential medicine is the backbone of health care system. An effective plan and appropriate strategies are vital to combat such future emergencies.

Orthodontic emergencies and mental health of patients undergoing orthodontic treatment during COVID-19 pandemic: A questionnaire study

Objectives

To evaluate the impact of COVID-19 pandemic on orthodontic treatment and mental health of patients undergoing orthodontic treatment and to compare their mental health with the age-matched control group.

Materials and methods

484 orthodontic patients (245 males and 239 females) and 200 age-matched control subjects were divided into two age groups. Group 1 had 14-18 years of adolescents (N = 274) and 100 control participants (Group 2) and Group 3 comprised of 19 years above adults (N = 210) and 100 control participants (Group 4). Group 1 and 3 patients filled the 4 sections of the questionnaire related to orthodontic emergencies (Sections 1-3) and mental distress (Kessler Psychological Distress Scale-Section 4), while groups 2 and 4 were asked to fill only Section-4. The comparison of mental distress on high/low Kessler scores was made using the Chi-Square test/Fisher's exact test. The factors which came out to be significant were put to bivariate logistic regression analysis.

Results

The percentage of patients with high Kessler scores among Group 1 and Group 3 were 9.9% and 17.2% respectively, and their differences with age-matched control groups were non-significant. The mean differences of Kessler score were significantly higher for Group 3 compared to group 1. The higher Kessler score was associated with age, higher education, a feeling of concern for non-availability of appointments, increased treatment duration, its effect on the quality of treatment, and sabotaging of definitive future plans.

Conclusions

The orthodontic treatment and emergencies may not be a significant factor contributing to increased stress among patients during the lockdown.

Pulmonary artery enlargement: an independent risk factor for mortality in hospitalized COVID-19 patients

Objective

To assess whether baseline pulmonary artery diameter (PAD), obtained from Non-contrast non-gated computed tomography (NCCT), can be associated with COVID-19 outcomes.

Patients and Methods

This is a retrospective study of hospitalized COVID-19 patients admitted to Hôtel-Dieu de France university hospital (Beirut, Lebanon) between March 2020 and March 2021. PAD was measured on baseline NCCT. Various outcomes were assessed, including hospital length of stay, ICU admission, invasive mechanical ventilation, mortality, and post-covid functional scale (PCFS) status at discharge and at 2-month follow-up.

Results

465 patients had a baseline NCCT, including 315 males (67.7%) with a mean age of 63.7±16 years. Baseline PAD was higher in critically ill patients admitted to the ICU (mean difference 0.8 mm [95% CI 0.4-1.59 mm]) and those receiving invasive mechanical ventilation (mean difference 1.1 mm [95% CI 0.11-2.04 mm]). PAD at baseline correlated significantly with hospital length of stay (r = 0.130, p=0.005), discharge status (r=0.117, p=0.023) and with PCFS at 2-month follow-up (r=0.121, p=0.021). Moreover, multivariable logistic regression showed that a PAD ≥ 24.5 mm independently predicted in-hospital all-cause mortality remained unaffected in COVID-19 patients (OR 2.07 (95% CI 1.05 - 4.09)).

Conclusion

Baseline PAD measurement using NCCT can be a useful prognostic parameter. Its measurement can help identify early severe cases and adapt the initial management of hospitalized Covid-19 patients.

Long-term impact of HPV vaccination and COVID-19 pandemic on oropharyngeal cancer incidence and burden among men in the USA: A modeling study

BACKGROUND

Oropharyngeal cancer (OPC) incidence is rising rapidly among men in the United States of America (USA). We aimed to project the impact of maintaining the current HPV vaccination uptake and achieving 80% national (Healthy People) goal on OPC incidence and burden.

METHODS

We developed an open-cohort micro-simulation model of OPC natural history among contemporary and future birth cohorts of men, accounting for sexual behaviors, population growth, aging, and herd immunity. We used data from nationally representative databases, cancer registries from all 50 states, large clinical trials, and literature. We evaluated the status quo scenario (the current HPV vaccination uptake remained stable) and alternative scenarios of improvements in uptake rates in adolescents (aged 9-17 years) and young adults (aged 18-26 years) by 2025 to achieve and maintain the 80% goal. The primary outcome was to project OPC incidence and burden from 2009 to 2100. We also assessed the impact of disruption in HPV vaccine uptake during the COVID-19 pandemic.

FINDINGS

OPC incidence is projected to rise until the mid-2030s, reaching the age-standardized incidence rate of 9·8 (95% uncertainty interval [UI] 9·5-10·1) per 100 000 men, with the peak annual burden of 23 850 (UI, 23 200-24 500) cases. Under the status quo scenario, HPV vaccination could prevent 124 000 (UI, 117 000-131 000) by 2060, 400 000 (UI, 384 000-416 000) by 2080, and 792 000 (UI, 763 000-821 000) by 2100 OPC cases among men. Achievement and maintenance of 80% coverage among adolescent girls only, adolescent girls and boys, and adolescents plus young adults could prevent an additional number of 100 000 (UI, 95 000-105 000), 118 000 (UI, 113 000-123 000), and 142 000 (UI, 136 000-148 000) male OPC cases by 2100. Delayed recovery of the HPV vaccine uptake during the COVID-19 pandemic could lead to 600 (UI, 580-620) to 6200 (UI, 5940-6460) additional male OPC cases by 2100, conditional on the decline in the extent of the national HPV vaccination coverage and potential delay in rebounding.

INTERPRETATION

Oropharyngeal cancer burden is projected to rise among men in the USA. Nationwide efforts to achieve the HPV vaccination goal of 80% coverage should be a public health priority. Rapid recovery of the declined HPV vaccination uptake during the COVID-19 pandemic is also crucial to prevent future excess OPC burden.

Cerebral Micro-Structural Changes in COVID-19 Patients - An MRI-based 3-month Follow-up Study

BACKGROUND

Increasing evidence supported the possible neuro-invasion potential of SARS-CoV-2. However, no studies were conducted to explore the existence of the micro-structural changes in the central nervous system after infection. We aimed to identify the existence of potential brain micro-structural changes related to SARS-CoV-2.

METHODS

In this prospective study, diffusion tensor imaging (DTI) and 3D high-resolution T1WI sequences were acquired in 60 recovered COVID-19 patients (56.67% male; age: 44.10 ± 16.00) and 39 age- and sex-matched non-COVID-19 controls (56.41% male; age: 45.88 ± 13.90). Registered fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD) were quantified for DTI, and an index score system was introduced. Regional volumes derived from Voxel-based Morphometry (VBM) and DTI metrics were compared using analysis of covariance (ANCOVA). Two sample t-test and Spearman correlation were conducted to assess the relationships among imaging indices, index scores and clinical information.

FINDINGS

In this follow-up stage, neurological symptoms were presented in 55% COVID-19 patients. COVID-19 patients had statistically significantly higher bilateral gray matter volumes (GMV) in olfactory cortices, hippocampi, insulas, left Rolandic operculum, left Heschl's gyrus and right cingulate gyrus and a general decline of MD, AD, RD accompanied with an increase of FA in white matter, especially AD in the right CR, EC and SFF, and MD in SFF compared with non-COVID-19 volunteers (corrected p value <0.05). Global GMV, GMVs in left Rolandic operculum, right cingulate, bilateral hippocampi, left Heschl's gyrus, and Global MD of WM were found to correlate with memory loss (p value <0.05). GMVs in the right cingulate gyrus and left hippocampus were related to smell loss (p value <0.05). MD-GM score, global GMV, and GMV in right cingulate gyrus were correlated with LDH level (p value <0.05).

INTERPRETATION

Study findings revealed possible disruption to micro-structural and functional brain integrity in the recovery stages of COVID-19, suggesting the long-term consequences of SARS-CoV-2.
