Non- adherence to anti-retroviral medication in Shiraz, 2014: a cross sectional study

Background: Medication adherence is a dynamic and complex behavioral process, which is strongly influenced by personal, social and environmental factors.Objectives: To determine the prevalence and factors affecting non-adherence to medication among HIV-infected patients.Methods and materials:Design: A cross-sectional study.Setting: Voluntary Counseling and Testing Center (VCT), Shiraz, Fars province, in the South of Iran.Patients: Among HIV-positive patients who received anti-retroviral therapy, 214 adult patients were selected through convenience sampling. Their medication adherence was checked by interview and counting the pills on visits during two months. Clinical and laboratory data were obtained from the patients' records.Results: Non-adherence and adherence groups included 30.4% (65) and 69.6% (149) of the patients, respectively. The mean age of patients was 40.80±7.77 years, and ranged from 20 to 65 years. Majority of cases (65%) were male. A significant relationship was found between non-adherence to medications and the variables of transmission method, marital status, housing status, and CD4, but there was no significant relationship with gender.Conclusion: The prevalence of medication adherence was similar to other regions with limited financial resources. To increase patient’s medication adherence, they should be exposed to motivational interventions to promote their drug consumption, social and occupational support.Keywords: Prevalence, adherence, anti-retroviral medication, HIV

Development of Muscle Disuse Model in Rat: Effect of Denervation and Tenotomization on the Skeletal Muscle Mechanics

Denervation refers to the condition that represents loss of nerve connection with the muscle. The term tenotomization or tenotomy refers to the condition where the tendon of the skeletal muscle is damaged. Both these conditions lead towards muscle disuse and then deterioration. It may be caused by some diseases, chemical toxicity, physical injury or intentional surgical interruption. To observe the effects of denervation and tenotomy, it is important to develop an animal model with such pathological conditions for a better understanding and investigation of a possible cure. Current study was designed to develop an animal model in rat for denervation and tenotomy. The objectives were to optimize the anaesthetic dose for rats, to develop muscle disuse models in rats including denervation and tenotomization and to determine the mechanical and physiological properties of the gastrocnemius muscle of the animal model for muscle disuse. Gastrocnemius muscle of the rat was targeted for study. Models were developed by surgical procedures. We succeeded in developing the rat model for both conditions and it was verified by observing the changes in the physiological properties of muscles

Perceived change in tobacco use and its associated factors among older adults residing in rohingya refugee camps during the covid-19 pandemic in Bangladesh

This study explored the perceived change in tobacco use during the COVID-19 pandemic and its associated factors among older adults residing in Rohingya refugee camps, also referred to as Forcibly Displaced Myanmar Nationals in Bangladesh. The study followed a cross-sectional design and was conducted in October 2020 among 416 older adults aged 60 years and above. A purposive sampling technique was applied to identify eligible participants, and face-to-face interviews were conducted using a pre-tested semi-structured questionnaire to collect the data. Participants were asked if they noted any change in their tobacco use patterns (smoking or smokeless tobacco) during the COVID-19 pandemic compared to pre-pandemic. Binary logistic regression models determined the factors associated with the perceived change in tobacco use. More than one in five participants (22.4%) were current tobacco users, of whom 40.8% reported a perceived increase in tobacco use during the COVID-19 pandemic. Adjusted analysis revealed that participants who were concerned about COVID-19 had significantly (p < 0.05) lower odds of perceived increase in tobacco use (aOR = 0.22, 95% CI: 0.06–0.73), while older adults who were overwhelmed by COVID-19 (aOR = 0.26, 95% CI: 0.06–1.18) and communicated less frequently with others during the pandemic than before (aOR = 0.19, 95% CI: 0.03–1.20) had marginally significantly (p < 0.1) lower odds of perceived increase in tobacco use during this pandemic. Relevant stakeholders, policymakers, and practitioners need to focus on strengthening awareness-raising initiatives as part of an emergency preparedness plan to control tobacco use during such a crisis period. © 2021 by the authors.

Changes in loneliness prevalence and its associated factors among Bangladeshi older adults during the COVID-19 pandemic

Aims Worldwide, loneliness is one of the most common psychological phenomena among older adults, adversely affecting their physical and mental health conditions during the COVID-19 pandemic. This study aims to assess changes in the prevalence of loneliness in the two timeframes (first and second waves of COVID-19 in Bangladesh) and identify its correlates in pooled data. Methods This repeated cross-sectional study was conducted on two successive occasions (October 2020 and September 2021), overlapping with the first and second waves of the COVID-19 pandemic in Bangladesh. The survey was conducted remotely through telephone interviews among 2077 (1032 in the 2020-survey and 1045 in the 2021-survey) older Bangladeshi adults aged 60 years and above. Loneliness was measured using the 3-item UCLA Loneliness scale. The binary logistic regression model was used to identify the factors associated with loneliness in pooled data. Results We found a decline in the loneliness prevalence among the participants in two survey rounds (51.5% in 2021 versus 45.7% in 2020; P = 0.008), corresponding to 33% lower odds in the 2021-survey (AOR 0.67, 95% CI 0.54-0.84). Still, nearly half of the participants were found to be lonely in the latest survey. We also found that, compared to their respective counterparts, the odds of loneliness were significantly higher among the participants without a partner (AOR 1.58, 95% CI 1.20-2.08), with a monthly family income less than 5000 BDT (AOR 2.34, 95% CI 1.58-3.47), who lived alone (AOR 2.17, 95% CI 1.34-3.51), with poor memory or concentration (AOR 1.58, 95% CI 1.23-2.03), and suffering from non-communicable chronic conditions (AOR 1.55, 95% CI 1.23-1.95). Various COVID-19-related characteristics, such as concern about COVID-19 (AOR 1.28, 95% CI 0.94-1.73), overwhelm by COVID-19 (AOR 1.53, 95% CI 1.14-2.06), difficulty earning (AOR 2.00, 95% CI 1.54-2.59), and receiving routine medical care during COVID-19 (AOR 2.08, 95% CI 1.61-2.68), and perception that the participants required additional care during the pandemic (AOR 2.93, 95% CI 2.27-3.79) were also associated with significantly higher odds of loneliness. However, the odds of loneliness were significantly lower among the participants with formal schooling (AOR 0.71, 95% CI 0.57-0.89) and with a family of more than four members (AOR 0.76, 95% CI 0.60-0.96). Conclusions The current study found a decreased prevalence of loneliness among Bangladeshi older adults during the ongoing pandemic. However, the prevalence is still very high. The findings suggest the need for mental health interventions that may include improving social interactions increasing opportunities for meaningful social connections with family and community members and providing psychosocial support to the vulnerable population including older adults during the pandemic. It also suggests that policymakers and public health practitioners should emphasise providing mental health services at the peripheral level where the majority of older adults reside

Loneliness and its correlates among Bangladeshi older adults during the COVID-19 pandemic

The present study aims to investigate the prevalence of loneliness and its associated factors among older adults during the COVID-19 pandemic in Bangladesh. This cross-sectional study was conducted in October 2020 among 1032 older Bangladeshi adults aged 60 years and above through telephone interviews. A semi-structured questionnaire was used to collect information on participants’ characteristics and COVID-19-related information. Meanwhile, the level of loneliness was measured using a 3-item UCLA Loneliness scale. More than half (51.5%) of the older adults experienced loneliness. We found that participants formally schooled [adjusted odds ratio (aOR = 0.62, 95% CI 0.43–0.88)] and received COVID-19-related information from health workers (aOR = 0.33, 95% CI 0.22–0.49) had lower odds of being lonely during the pandemic. However, older adults living alone (aOR: 2.57, 95% CI 1.34–4.94), residing distant from a health facility (aOR = 1.46, 95% CI 1.02–2.08) and in rural areas (aOR = 1.53, 95% CI 1.02–2.23) had higher odds of loneliness than their counterparts. Likewise, odds of loneliness were higher among those overwhelmed by COVID-19 (aOR = 1.93, 95% CI 1.29–2.86), who faced difficulty in earning (aOR = 1.77, 95% CI 1.18–2.67) and receiving routine medical care during pandemic (aOR = 2.94, 95% CI 1.78–4.87), and those perceiving requiring additional care during the pandemic (aOR = 6.01, 95% CI 3.80–9.49). The findings suggest that policies and plans should be directed to reduce loneliness among older adults who require additional care

Global COVID-19 vaccine equity and the booster dose in low-resource countries : a decolonizing global health perspective

On July 30, 2021, the administration of a third (booster) dose of the COVID-19 vaccine was introduced to enhance immunity among vaccinated people. Many developed countries have introduced vaccine booster doses as additional protection for their population to mitigate the severity of the ongoing COVID-19 pandemic. However, this idea is currently being replicated by low- and lower-middle-income countries (LMICs), where full vaccination coverage is, as of now, still below 45%, which is considerably lower than that of high-income countries (73%). This commentary focuses on the critiques of introducing booster dose strategy in low-income countries. We highlight different decolonizing global health perspectives, including vaccine equity, effective resource utilization, and priority setup, in this commentary

Global Functional Atlas of \u3cem\u3eEscherichia coli\u3c/em\u3e Encompassing Previously Uncharacterized Proteins

One-third of the 4,225 protein-coding genes of Escherichia coli K-12 remain functionally unannotated (orphans). Many map to distant clades such as Archaea, suggesting involvement in basic prokaryotic traits, whereas others appear restricted to E. coli, including pathogenic strains. To elucidate the orphans’ biological roles, we performed an extensive proteomic survey using affinity-tagged E. coli strains and generated comprehensive genomic context inferences to derive a high-confidence compendium for virtually the entire proteome consisting of 5,993 putative physical interactions and 74,776 putative functional associations, most of which are novel. Clustering of the respective probabilistic networks revealed putative orphan membership in discrete multiprotein complexes and functional modules together with annotated gene products, whereas a machine-learning strategy based on network integration implicated the orphans in specific biological processes. We provide additional experimental evidence supporting orphan participation in protein synthesis, amino acid metabolism, biofilm formation, motility, and assembly of the bacterial cell envelope. This resource provides a “systems-wide” functional blueprint of a model microbe, with insights into the biological and evolutionary significance of previously uncharacterized proteins
