Abstract
Human spaceflight has historically been managed by government agencies, such as the NASA Twins Study1, but new commercial spaceflight opportunities have opened spaceflight to a broader population. In 2021, the SpaceX Inspiration4 mission launched the first-ever all civilian crew to low Earth orbit, which included the youngest American astronaut (age 29), novel in-flight experimental technologies (handheld ultrasound imaging, smartwatch wearables, and immune profiling), ocular alignment measurements, and new protocols for in-depth, multi-omic molecular and cellular profiling. Here we report the primary findings from the 3-day spaceflight mission, which induced a broad range of physiological and stress responses, neurovestibular changes indexed by ocular misalignment, and altered neurocognitive functioning, some of which match long-term spaceflight2, but almost all of which did not differ from baseline (pre-flight) after return to Earth. Overall, these preliminary civilian spaceflight data suggest that short-duration missions do not pose a significant health risk, and moreover present a rich opportunity to measure the earliest phases of adaptation to spaceflight in the human body at anatomical, cellular, physiologic, and cognitive levels. Finally, these methods and results lay the foundation for an open, rapidly expanding biomedical database for astronauts3, which can inform countermeasure development for both private and government-sponsored space missions.

Abstract
Long-term exposure to ambient air pollution raises the risk of deaths and morbidity worldwide. From 1990 to 2019, we observed the epidemiological trends and age-period-cohort effects on the cardiovascular diseases (CVD) burden attributable to ambient air pollution across Brazil, Russia, India, China, and South Africa (BRICS). The number of CVD deaths related to ambient particulate matter (PM) pollution increased nearly fivefold in China [5.0% (95% CI 4.7, 5.2)] and India [5.7% (95% CI 5.1, 6.3)] during the study period. The age-standardized CVD deaths and disability-adjusted life years (DALYs) due to ambient PM pollution significantly increased in India and China but decreased in Brazil and Russia. Due to air pollution, the relative risk (RR) of premature CVD mortality (< 70 years) was higher in Russia [RR 12.6 (95% CI 8.7, 17.30)] and India [RR 9.2 (95% CI 7.6, 11.20)]. A higher period risk (2015-2019) for CVD deaths was found in India [RR 1.4 (95% CI 1.4, 1.4)] followed by South Africa [RR 1.3 (95% CI 1.3, 1.3)]. Across the BRICS countries, the RR of CVD mortality markedly decreased from the old birth cohort to young birth cohorts. In conclusion, China and India showed an increasing trend of CVD mortality and morbidity due to ambient PM pollution and higher risk of premature CVD deaths were observed in Russia and India.

Abstract
We present green synthesis of silver nanoparticles in water using unirradiated and Ag15 + ion irradiated phytoextracts of Bergenia Ciliata leaf, Eupatorium adenophorum leaf, Rhododendron arboreum leaf and flower. The use of different plant extracts and their subsequent ion irradiation allow for successful refinement of nanoparticle size and morphology. Due to changes in reducing and capping agents the nanoparticle surface functionalization also varies which not only controls the morphology but also allows for surface oxidation and aggregation processes. In this work, we have synthesized silver nanoparticles which exhibit sizes in the range from 13 to 24 nm and having shapes like spherical, quasispherical, trigonal, hexagonal, cylindrical, dendritic assemblies, and porous nanoparticles. Owing to changes in the size and shape of the nanoparticles, their direct bandgap (2.05 eV - 2.48 eV) and local surface plasmon resonance (420 nm - 490 nm) could also be tuned. These nanoparticles are examined as SERS substrates, where their enhancement factors, limit of detection for methylene blue, and SERS substrate homogeneity have been tested. It has been observed the nanoparticles synthesized using unirradiated plant extracts present an enhancement factor of 106 with a limit of detection 10- 8 M. Whereas nanoparticles with refined morphology and shapes upon irradiation present high enhancement factors of >107 and detection limit down to 10- 9 M. In addition, uniformity in Raman spectra over the SERS substrates has been obtained for selected Ag NPs substrates synthesized using irradiated extracts with minimum relative standard deviation in enhancement factor < 12%.

Abstract
Pakistan is facing a high prevalence of malnutrition and Minimum Dietary Diversity (MDD) is one of the core indicators that remain below the recommended level. This study assesses MDD and its associated factors among children aged 6 to 23 months in Pakistan. The study uses a cross-sectional study using the dataset of the latest available Multiple Indicators Cluster Survey (MICS) for all provinces of Pakistan. Multistage sampling is used to select 18,699 children aged 6 to 23 months. The empirical method is the Logistic Regression Analysis and Chi-Square Test. The dataset is freely and publicly available with all identifier information removed, and no ethics approvals are required. About one-fifth (20%) of infants and young children aged 6 to 23 months had met MDD, this number varies from 17 to 29%, highest in Baluchistan and lowest in Punjab province of Pakistan. The age group (18-23) indicates a 2.45 times greater chance of having MDD. Age (< 0.001), diarrhea (0.01), prenatal care (0.06), mother's education (< 0.001), computer access (< 0.001), wealth quantile (< 0.001), and residence (< 0.001) were significantly associated with meeting MDD. However, gender (0.6) and mother's age (0.4) both were statistically insignificant in meeting MDD. Regarding mothers' education, compared to no education, the chance of MDD is 1.45 times greater for highly educated mothers in the Punjab province. Dietary diversity among children aged 6 to 23 months in Pakistan is low. It is recommended that mothers should be aware and encouraged to use dietary diverse food for infants and younger children.

Abstract
Freshwater habitats hold a unique role in the survival of all living organisms and supply water for drinking, irrigation, and life support activities. In recent decades, due to anthropogenic activities, deterioration in the water quality has been a long-lasting problem and challenge to the scientific fraternity. Although, these freshwater bodies have a bearable intrinsic capacity for pollution load however alarming increase in pollution limits the intrinsic capacities and requires additional technological interventions. The release of secondary pollutants from conventional interventions further needs revisiting the existing methodologies and asking for green interventions. Green interventions such as phycoremediation are natural, eco-friendly, economic, and energy-efficient alternatives and provide additional benefits such as nutrient recovery, biofuel production, and valuable secondary metabolites from polluted freshwater bodies. This systemic review in a nut-shell comprises the recent research insights on phycoremediation, technological implications, and influencing factors, and further discusses the associated mechanisms of metal ions biosorption by living and non-living algae, its advantages, and limitations. Besides, the article explores the possibility of future research prospects for applicability at a field scale that will help in the efficient utilization of resources, and improved ecological and health risks.

Abstract
PURPOSE Studies on inguinal hernia repair in patients with ascites are limited, small, and inconsistent, exacerbating a challenging clinical dilemma for surgeons. To fill this gap in the literature, this retrospective cohort study used a national US database to examine the impact of ascites on the outcomes of open inguinal herniorrhaphy. METHODS Patients who underwent open inguinal herniorrhaphy between 2005 and 2019 were identified in the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database. Two groups were defined by the presence or absence of nonmalignant preoperative ascites. Ascites patients were propensity matched 1:10 with non-ascites patients. Surgical outcomes at 30 days for the matched groups, stratified by electiveness of procedure, were compared, with the primary end points of mortality and the NSQIP composite outcome "serious complication". RESULTS The study included 682 patients with ascites. Compared to matched controls, those with ascites had significantly increased odds of mortality (OR 3.3, 95% CI 1.5-7.0) after elective repair, but not after nonelective repair. Ascites was associated with increased odds of serious complication after both elective (OR 1.7, 1.2-2.3) and nonelective (OR 2.0, 1.3-3.0) surgery. Among ascites patients, age ≥ 65 years was associated with increased mortality (risk-adjusted OR 3.8, 1.2-14.4) and serious complication (OR 2.2, 1.2-3.9). CONCLUSION In this largest study to date on patients with ascites undergoing open inguinal herniorrhaphy, ascites increased the odds of mortality after elective repair and of serious complication after elective and nonelective repair. Age ≥ 65 was a risk factor for poor outcome. Inguinal herniorrhaphy is fraught with complications in this population.

Abstract
Background Maternal and child healthcare service delivery in vulnerable and fragile health systems has suffered a tremendous impact owing to the shift in focus to curtail the COVID-19 pandemic. We aimed to evaluate the impact of the COVID-19 pandemic on maternal and child healthcare services to inform policy advice for a more resilient maternal and child healthcare service delivery in Pakistan. Methods A descriptive cross-sectional study was conducted. A structured and validated questionnaire was transformed into an online version and a link was first sent to about 300 healthcare professionals to achieve a sample size of 203, including medical doctors, nurses, and other paramedical staff working in public sector health facilities of the four provinces of Pakistan. The questionnaire was responded to by 195 participants. The Chi-Square test was used to determine the statistical differences between the categorical variables. Results Although about two-thirds of the participants reported a moderate adherence to protocols and procedures to prevent COVID-19 in their health facilities, the maternal and child health service delivery-related indicators declined during the pandemic. For instance, 66.8% and 62.4% of the participants, respectively, did not agree that a Neonatal Intensive Care Unit and an Intensive Care Unit to admit sick newborns and women with obstetric complications during the COVID-19 pandemic were available during the COVID-19 pandemic. In addition, 23% and 20% of the participants, respectively, reported that staff availability and the provision of cesarean section were moderate to extremely affected. The association between job designation and the impact of COVID-19 was statistically significant (χ2 p = 0.038). Conclusions The study suggests that maternal and child healthcare services including C-Section, perinatal care, and inpatient care of newborns in Pakistan may have been moderately affected by the COVID-19 pandemic.

Abstract
BACKGROUND Considering the high maternal mortality rate, the government of Pakistan has deployed Community Midwives (CMWs) in rural areas of Pakistan. This relatively new cadre of community-based skilled birth attendants has previously reported to experience several challenges in providing maternal and child healthcare. However, what barriers they experience in providing basic emergency obstetric and newborn care needs to be further studied. METHODS This was a cross-sectional study conducted in twelve districts in Sindh province, Pakistan, with poor maternal and child health indicators. A total of 258 CMWs participated in this study and completed the questionnaire on a pretested, validated tool in their community-based stations. The trained data collectors completed the questionnaires from the respondents. The problems identified were categorized into three major issues: financial, and transport and security related; and were analyzed accordingly. Ethical approval was obtained from the institutional review board (IRB) of Health Services Academy (HSA) Islamabad, Pakistan. RESULTS The majority (90%) of 258 CMWs had formal training in maternal and neonatal care from the recognized institutions. Financial difficulties faced by CMWs were identified as the most frequent barriers and others were transport, security, and other issues. In univariate analysis, 38.1% and 61.9% of the community midwives who faced financial difficulties had completed a graduation or intermediate level of education, respectively (p = 0.006). Round-the-clock availability for emergencies was inversely associated with having financial difficulties, i.e., 71.4%, in contrast to 28.4% who had financial difficulties were available round-the-clock for emergency calls in their community clinics (p = 0.008). Formal training (p = 0.001), work experience (p = 0.015), longer duration of work (p = 0.003), and liaison with health workers and posting district (p = 0.001) had statistically significantly higher transport related issues. Security difficulties faced by CMWs and a set of correlates such as formal training (p = 0.019), working experience (p = 0.001), longer duration of work (p = 0.023), 24 h of availability on call (p = 0.004), liaison with traditional birth attendants (TBAs) in the community (p = 0.002), and district of posting (p = 0.001) were statistically significantly different. Other issues like working experience (p = < 0.001) and Liaison with TBAs in the community (p = < 0.001) were found statistically significant. CONCLUSION Financial, transportation and security related barriers were commonly reported by community midwives in the delivery of basic emergency obstetric and newborn care in rural Pakistan.

Abstract
BACKGROUND This study investigates the factors associated with maternal health services utilization in Pakistan using two outcome indicators, ideal antenatal care (IANC), defined as the pregnant woman receiving all the essential services included in standard antenatal care, and skilled birth attendance (SBA). METHODS This study used the Pakistan Maternal Mortality Survey 2019 data. The study utilized binary logistic regression models to investigate the adjusted association between the outcome variables, separately for IANC and SBA, and the independent variables, education, wealth, parity, and residence. RESULTS Wealth showed a positive association with utilization of IANC (adjusted odds ratio [AOR] = 11.48, 95% CI = 7.76, 16.99) and SBA (AOR = 4.37, 95% CI = 3.30,5. 80). Maternal age was associated only with IANC for women aged 35 or more years (AOR = 1.31, 95% CI = 1.06, 1.62). Increased likelihood of utilization of IANC and SBA services was also observed for women with formal education. Women who had 3-5 previous live births had higher odds of using IANC and SBA than women who had 1-2 or more than five previous live births. Urban residency was not correlated with either IANC or SBA. CONCLUSION When compared to the wealthy and educated quintile, women in the lower wealth quintile and those without any formal education were less likely to utilize ANC and SBA services. A comprehensive and multipronged approach from the health and education sectors is needed to improve maternal health in Pakistan.

Abstract
Background and Objectives: Respectful maternity care promotes practices that acknowledge women's preferences and women and newborns' needs. It is an individual-centered strategy founded on ethical and human rights principles. The objective of this systematic review is to identify the impact of income on maternal care and respectful maternity care in low- and middle-income countries. Materials and Methods: Data were searched from Google Scholar, PubMed, Web of Science, NCBI, CINAHL, National Library of Medicine, ResearchGate, MEDLINE, EMBASE database, Scopus, Cochrane Central Register of Controlled Trials (CENTRAL), and Maternity and Infant Care database. This review followed PRISMA guidelines. The initial search for publications comparing low- and middle-income countries with respectful maternity care yielded 6000 papers, from which 700 were selected. The review articles were further analyzed to ensure they were pertinent to the comparative impact of income on maternal care. A total of 24 articles were included, with preference given to those published from 2010 to 2023 during the last fourteen years. Results: Considering this study's findings, respectful maternity care is a crucial component of high-quality care and human rights. It can be estimated that there is a direct association between income and maternity care in LMICs, and maternity care is substandard compared to high-income countries. Moreover, it is determined that the evidence for medical tools that can enhance respectful maternity care is sparse. Conclusions: This review highlights the significance of improving maternal care experiences, emphasizing the importance of promoting respectful practices and addressing disparities in low- and middle-income countries.

Abstract
INTRODUCTION According to American Heart Association standards, hypertension is classified into three stages based on blood pressure measurements: essential hypertension, stage 1 hypertension, and stage 2 hypertension. The global target is to reduce the prevalence of high blood pressure by 25% by the year 2025. Worldwide, the prevalence of high blood pressure among men and women aged 18 and above reported to be 24% and 20%, respectively. AIM The aim of this study was to overall reduce high blood pressure of hypertensive patients to the recommended level of 140/90 mm of Hg through implementing a non-pharmacological and multi-component intervention based on Disease Control Priorities (3rd edition). METHODS A randomized controlled trial in which a multi-component intervention for lowering high blood pressure was tested. This was pilot-tested for its acceptance, appropriateness, and relevance, explored through an earlier formative research and desk review conducted from the available evidence. A total of 240 study participants were enrolled after obtaining informed consent. Ethical approval was obtained from the Institutional Review Board of Health Services Academy and the trial was registered in clinicaltrials.gov number NCT04336631. SPSS software version 21 was used to enter and analyze the data. RESULTS High blood pressure of hypertensive patients in a hospital setting during 03 months yielded -23.9 mm Hg of systolic blood pressure reduction (95% confidence interval, p ≤ 0.005). A significant reduction was observed in intervention group after delivering the intervention. Compared to patients in the usual care group, improved health outcomes were achieved for diet control, reducing salt intake and increased physical exercise. In the intervention group, the mean blood pressure among male hypertensive patients was 145/90 mm Hg and in female hypertensive patients, the mean blood pressure was recorded as 140/100 mm Hg. CONCLUSION High blood pressure was significantly reduced in hypertensive patients who adhered to a low salt diet, weight loss measures, and increased physical activity.

Abstract
OBJECTIVES The objective of this study was to determine the prevalence and correlates of early initiation of breast feeding and prelacteal feeding in highly disadvantaged districts in Pakistan. DESIGN This cross-sectional study design. SETTINGS This study was carried out in twelve districts of the Sindh province of Pakistan. PARTICIPANTS A total of 4800 mothers with children under 2 years, selected through a multistage random sampling method. DATA ANALYSIS Bivariate association, survival analysis (Kaplan-Meier and Cox proportional hazard techniques), multivariate linear regression and the ordinary least square model were used. RESULTS The results show that the prevalence of early initiation of breast feeding was 68% and prelacteal feeding was 32%. Adequate treatment, proper guidance at antenatal care visits, postpartum health check, normal birth with skilled birth attendants, institutional birth, skin-to-skin contact at birth and birth size were all associated with early breastfeeding initiation (p<0.001). The odds of early initiation of breast feeding after birth are higher if the respondents received proper guidance (OR 2.05; 95% CI 1.02 to 4.11) or made skin-to-skin contact (OR 10.65; 95% CI 6.82 to 16.65). Bivariate association between the prelacteal feeding and a set of correlates suggests that all variables under study were significantly associated with the outcome variable of interest at a 95% or higher significance level. The factors which significantly reduced the odds of prelacteal feeding were adequate treatment (OR 0.29; 95% CI 0.23 to 0.37) and postpartum health check (OR 0.65; 95% CI 0.53 to 0.80). CONCLUSION Sudy concludes that the correlates like adequate treatment of mothers during labour, postpartum health check-up, normal birth with skilled birth attendants, institutional births and skin-to-skin contact between mother and the baby determine the early initiation of breast feeding and prelecteal feeding. Early initiation of breast feeding needs to be encouraged, and communities must be educated against the use of prelacteal feeding.

Abstract
BACKGROUND Person-Centered Maternity Care (PCMC) is known as one of the most important components of maternal care. Every woman has the ultimate right of respectful health care. Previous research documents that lack of supportive care and respectful behavior experienced by pregnant women can act as a barrier to the utilization of health care services. Few studies have used PCMC tool to document this phenomenon. The objective of this descriptive study was to assess the women's perception of PCMC in Pakistan. METHODS Three hundred and seventy-seven (377) postnatal women of ages 18-49 years participated in the research. The study sites were secondary and tertiary care hospitals located in the twin cities of Rawalpindi and Islamabad. The PCMC tool used in this study is a validated scale with three sub-domains of i) communication and autonomy, ii) supportive care, and iii) dignity and respect. Data was analyzed using SPSS version 16, and descriptive and bivariate analysis was undertaken. RESULTS The PCMC mean score was 54 ± [10.7] out of 90. About half (55%) of women had good perception of PCMC. Sub-domain of supportive care scored the lowest as compared to the other two domains. Overall, 36% women reported physical abuse while 22% reported verbal abuse at the hands of the healthcare providers. Most of the women (88%) said that health providers did not introduce themselves. About 30% women claimed that health care providers never asked for permission before doing any medical procedures and 20% of women claimed that doctors did not describe the purpose of examination while 178 (47%) of women said that health provider explained the purpose of medications all the time, additionally, about 14% were never given the choice to ask questions. CONCLUSION The study concluded that the majority of postnatal women perceived that they were not getting optimum Person-Centered Maternity Care. Some core aspects in supportive care domain were missing. In order to improve the quality of hospital-based childbirths, efforts are needed to improve the quality of care.

Experience of psychologists in the delivery of cognitive behaviour therapy in a non-western culture for treatment of substance abuse: a qualitative study. Int J Ment Health Syst 2022; 16:55. [PMID: 36443829 PMCID: PMC9703777 DOI: 10.1186/s13033-022-00566-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/03/2022] [Accepted: 11/14/2022] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND Psychotherapy is the preferred form of treatment for psychological disorders worldwide. Cognitive behaviour therapy (CBT) is one of the most widely used psychotherapies due to its proven efficacy for psychological disorders, including substance abuse. However, CBT was developed in the West according to the culture of developed countries. Therefore, it requires cross-cultural adaptation for non-Western countries. Pakistan is one of the developing non-Western countries where substance use disorders are increasing at an alarming rate. Despite the proven efficacy of CBT for substance use disorders, there is a dearth of its utilization in Pakistan. Therefore, in the present study, in-depth qualitative interviews were conducted with CBT practitioners in Pakistan to understand barriers and challenges in this regard. The study was a part of a broader project aimed at cultural adaptation of CBT for people with substance use disorders (SUDs) in Pakistan. METHODS In-depth qualitative interviews were conducted with CBT practitioners (N = 8) working in rehabilitation centres and hospitals in Islamabad, Pakistan. Thematic content analysis was conducted to develop core themes from the data. RESULTS CBT for SUDs requires some adjustments according to Pakistani culture for successful utilization. The challenges in providing CBT for SUDs revolved around three main themes, i.e., the mental health system, societal practices, and therapeutic issues, and 10 subthemes. CONCLUSION In order to utilize the benefits of CBT for SUDs in Pakistan, cultural adaptation is necessary as an initial step. However, its delivery requires stringent modifications in the health care system to address these challenges.

Abstract
The strategy of stacking two-dimensional materials for designing van der Waals heterostructures has gained tremendous attention in realizing innovative device applications in optoelectronics and renewable energy sources. Here, we performed the first principles calculations of the geometry, optoelectronic and photocatalytic performance of MS2-CrSSe (M = Mo, W) vdW heterostructures. The mirror asymmetry in the Janus CrSSe system allows the designing of two models of the MS2-CrSSe system by replacing S/Se atoms at opposite surfaces in CrSSe. The feasible configurations of both models of the MS2-CrSSe system are found energetically, dynamically and thermally stable. The studied heterobilayers possess an indirect type-I band alignment, indicating that the recombination of photogenerated electrons and holes in the CrSSe monolayer is hence crucial for photodetectors and laser applications. Remarkably, a red-shift in the optical absorption spectra of MS2-CrSSe makes them potential candidates for light harvesting applications. More interestingly, all heterobilayers (except W(Mo)S2-CrSSe of model-I(II)) reveal appropriate band edge positions of the oxidation and reduction potentials of the photocatalysis of water dissociation into H+/H2 and O2/H2O at pH = 0. These results shed light on the practical design of the MS2-CrSSe system for efficient optoelectronic and photocatalytic water splitting applications.

Khan MAA, Hamid S, Khan SA, Sarfraz M, Babar ZUD. A Qualitative Study of Stakeholders' Views on Pharmacovigilance System, Policy, and Coordination in Pakistan. Front Pharmacol 2022; 13:891954. [PMID: 35754475 PMCID: PMC9218668 DOI: 10.3389/fphar.2022.891954] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2022] [Accepted: 05/03/2022] [Indexed: 11/21/2022] Open
Abstract
Objectives: Due to the absence of necessary rules, poor coordination, and various challenges, the pharmacovigilance system of Pakistan is not optimally functional at all levels of the health system. The objective of the study was to assess the stakeholders’ perceptions of the current ADR reporting system and to identify the pharmacovigilance policy issues and problems of effective coordination. Methodology: Stakeholders from a broad range of disciplines, academia, regulatory authorities, the pharmaceutical industry, international health organizations, as well as pharmacovigilance experts, and healthcare professionals were included in the study. A total of 25 stakeholders throughout Pakistan were interviewed during exploratory semi-structured interviews. The interviews were recorded digitally, transcribed, coded, compared, and grouped according to their similarity of themes. Participants provided insights into gaps, limitations, and challenges of Pakistan’s current ADR reporting system, issues with proposed pharmacovigilance rules, and coordination difficulties. Results: The majority of the participants considered the ADR reporting system in Pakistan to be improving but in a nascent phase. The identified gaps, challenges, limitations of the system, and barriers to reporting were labeled as reasons for limited functioning. Almost all stakeholders were aware of the existence of draft pharmacovigilance rules; however, participants in the industry were familiar with the contents and context of draft pharmacovigilance rules. Bureaucratic red tape and lack of political will appeared to be the top reasons for delaying the approval of the pharmacovigilance rules. Wider consultation, advocacy, and awareness sessions of policymakers and HCPs were suggested for early approval of rules. Participants unanimously agreed that the approval of rules shall improve the quality of life and reduce the economic burden along with morbidity and mortality rates. The need for greater and collaborative coordination among the stakeholders in promoting medicines’ safety was highlighted. All participants suggested the use of media and celebrities to disseminate the safety information. Conclusion: Participants showed partial satisfaction with the way pharmacovigilance in Pakistan is moving forward. However, stakeholders believed that engagement of multi-stakeholders, approval of pharmacovigilance rules, and the establishment of pharmacovigilance centers in provinces, hospitals, and public health programs (PHPs) shall support in achieving the desired results.

Abstract
Local and exotic germplasm of tomato remains a major source for genetic improvement. Assessment of such lines for biotic stresses particularly viral diseases are the most important criteria for selection in Pakistan, where Tomato Yellow Leaf Curl Virus (TYLCV) and Tomato Mosaic Virus (ToMV) are the major diseases/viruses. A set of 40 accessions (including indigenous Pakistani lines and exotic germplasm from Europe, the United States, and Asia) were evaluated for their resistance/infection response to ToMV with artificial inoculation under greenhouse conditions. Infection response was quantified through disease scoring and DAS-ELISA test (for ToMV). A subset of 24 lines, was further screened for TYLCV using disease scoring and TAS-ELISA. The tested lines showed significant variability for resistance to ToMV. Only one accession (Acc-17878) was resistant to the ToMV whereas seven accessions i.e. Acc-17890, AVR-261, CLN-312, AVR-321, EUR-333, CLN-352, and CLN-362 expressed resistance to TYLCV. Correlation between phenotypic evaluation was confirmed by the ELISA results in both diseases, although both tools complemented to assess the viral infection status. In future, tomato breeding programs must consider breeding for ToMV and TYLCV resistance (using identified germplasm in our study) so as to deliver virus resistant tomato varieties.

Abstract
Increased anxiety and depressive symptoms have reported to be its association with long term illness. Because of having unwanted effects of newly available drugs, patients administering anxiolytic drugs usually discontinue the treatment before they are completely recovered. Therefore, there is a serious need to develop new anxiolytic drugs. The anxiolytic effect of hydro-alcoholic extract of Agaricus blazei in animal models was assessed. 24 male mice (Mus musculus genus) were included in the study. Four groups were prepared and each group contained six animals. The groups were vehicle control, positive control (diazepam 1.0 mg/kg, i.p.) as well as two treatment groups receiving Agaricus blazei hydro-alcoholic extract at a dose of 136.50 mg/kg and 273.0 mg/kg orally. The Marble burying test, Nestlet shredding test and Light and Dark box test used to assess anxiolytic activity. Mice administered with diazepam 1.0 mg/kg, i.p. while hydro-alcoholic extract of AbM (136.50 and 273.0 mg/kg, respectively) was administered via oral route which exhibited marked reduction in number of marbles-burying as compared to vehicle control group. Mice administered with diazepam 1.0 mg/kg, i.p. and Oral administration of hydro-alcoholic extract of AbM (136.50 and 273.0 mg/kg, respectively) exhibited significant decrease in nestlet shredding in comparison to vehicle control group. The oral administration of hydro-alcoholic extract at a dose of 136.5mg/kg and 273mg/kg showed elevation in time spent in light box and was comparable to standard treated group while time spent by mice following oral administration of hydro-alcoholic extract of Agaricus blazei at a dose of 273.0 mg/kg also showed elevation and was found to be more near to standard treated group (diazepam 1 mg/kg, i.p.).

Abstract
BACKGROUND Pharmacy practice education requires the development of proficiencies and an understanding of clinical microbiology. Learning in this area could be delivered using practical laboratory exercises, or potentially, simulation-based education. Simulation has previously successfully enhanced learning in health professional education. The current global climate due to COVID-19 has further highlighted the important role of technology-enhanced learning in delivering outcomes that meet the requisite learning objectives of a course. The aim of the present study was to compare the impact of a commercially available virtual microbiology simulation (VUMIE™) with a traditional wet laboratory (wetlab) on learner knowledge, skills and confidence in a second-year integrated pharmacotherapeutics course for Bachelor of Pharmacy students. METHODS A randomised, crossover study was employed to determine whether the simulation intervention (VUMIE™) improves learning outcomes (knowledge, skills and confidence) of pharmacy students, when compared to a traditional wetlab intervention. Each student completed three 1-2 h length sessions, for both the wetlab and VUMIE™ interventions (6 sessions total). Data was collected using surveys deployed at baseline (pre-interventions), post-intervention 1 or 2 (VUMIE™ or wetlab) and endpoint (post-interventions 1 and 2). Statistical analysis was conducted using SPSS Statistics 25 and Instat™ software. RESULTS Response rates were approximately 50% at initial survey and approximately 25% at endpoint survey. VUMIE™ produced higher post-intervention knowledge scores for the multiple-choice questions compared to the wetlab, however, the highest score was achieved at endpoint. Both interventions produced statistically significant differences for mean scores compared to baseline (pre-VUMIE™ and wetlab) across the domains of knowledge, skills and confidence. VUMIE™ produced higher post-intervention mean scores for knowledge, skills and confidence compared to post-intervention mean scores for the wetlab, however there was no statistical significance between the mean score for the two interventions, thus the VUMIE™ activity produced learning outcomes comparable to the wetlab activity. CONCLUSION These findings suggest VUMIE™ provides similar effects on students' knowledge, skills, and confidence as a wetlab. The simulation's implementation was not cost-prohibitive, provided students with a physically and psychologically safe learning environment, and the benefit of being able to repeat activities, supporting deliberate practice.

Abstract
Objective: To examine the impact of 30-day hospital readmission for non-communicable diseases on limited health-care resources of a low-income country like Pakistan in the light of available data from Pakistan’s Sehat Sahulat Program.
Study Design: Retrospective analytical cross-sectional study.
Place and Duration of Study: Health Services Academy, Islamabad Pakistan, from Jan 2016 to Jul 2020.
Methodology: Secondary data of patients readmitted with non-communicable diseases in Sehat Sahulat Program, Islamabad, Pakistan. Universal sampling technique was utilized. Data was analyzed using SPSS version 27.
Results: Islamabad (ICT) stands second highest for readmissions (n=1270) in which the 30-days readmission rate was 13.69%. Maximum number of readmissions were found in 50-59 years (344, 27.12%). Of 1270 ICT readmissions, 559 (44%) cases were readmitted with non-communicable diseases while rest of 711 (56%) cases were readmitted for acute infectious diseases or surgical procedures. Of 559 non-communicable diseases cases, 236 (42.21%) readmissions were having one non-communicable disease, 63 (11.27%) readmissions exhibited two or more non-communicable diseases and 260 (46.51%) were readmitted because of cancers (CA). Among males, the most common malignancy was CA lungs/ bronchus 24 (19.8%) while among females, CA Breast 80 (56.3%).
Conclusion: Non-communicable diseases represent a significant burden on resource constrained, low-income countries. In view of the recurrent admissions that these chronic diseases inevitably incur, better resource allocation may help lessen this burden on fragile health systems creating better clinical outcomes for the penurious strata of Pakistan’s population.

Abstract
We have evaluated the effects of different fish feeds on the body composition, growth, and enzyme activities of Labeo rohita (Rohu). In total, 240 fishes between the average weights of 24.77±2.15g were studied. The treatments were applied in a completely randomized design, with 4 treatments of 60 fishes each. Treatments consisted of four different fish feeds [Oryza (T1), AMG (T2), Aqua (T3), and Supreme (T4)]. Body composition, growth performance, and enzyme activities were evaluated. There was a significant variation in performance of fishes fed with different type of feed; as fishes having Oryza feed showed the highest weight gain, specific growth rate (SGR), and best feed conversion ratio (FCR) as compared to other groups that were considered to be significant (P ≤ 0.05). High net weight gain was obtained in T4 when compared with T2 and T3. FCR value of T4 was less than T1 but higher than T2, T3 and T2, which showed the lowest values. The specific growth rate was recorded as average in T4, but T2 led a high SGR than T3. Similarly, crude protein level and digestive enzymes activity was recorded significantly highest in fed with Oryza (T1) as compared to AMG (T2), Aqua (T3), and Supreme (T4). Water quality parameters were recorded significant in all treatments except pH and DO of treatment (T1), significantly different from other treatments. It was concluded that Rohu (Labeo rohita) could show a promising growth rate and protease enzyme activity when fed with the Oryza feed of 25% protein.

Abstract
Hospital readmissions pose a threat to the constrained health resources, especially in resource-poor low-and middle-income countries. In such scenarios, appropriate technologies to reduce avoidable readmissions in hospitals require innovative interventions. mHealth and teach-back communication are robust interventions, utilized for the reduction in preventable hospital readmissions. This review was conducted to highlight the effectiveness of mHealth and teach-back communication in hospital readmission reduction with a view to provide the best available evidence on such interventions. Two authors independently searched for appropriate MeSH terms in three databases (PubMed, Wiley, and Google Scholar). After screening the titles and abstracts, shortlisted manuscripts were subjected to quality assessment and analysis. Two authors checked the manuscripts for quality assessment and assigned scores utilizing the QualSyst tool. The average of the scores assigned by the reviewers was calculated to assign a summary quality score (SQS) to each study. Higher scores showed methodological vigor and robustness. Search strategies retrieved a total of 1932 articles after the removal of duplicates. After screening titles and abstracts, 54 articles were shortlisted. The complete reading resulted in the selection of 17 papers published between 2002 and 2019. Most of the studies were interventional and all the studies focused on hospital readmission reduction as the primary or secondary outcome. mHealth and teach-back communication were the two most common interventions that catered for the hospital readmissions. Among mHealth studies (11 out of 17), seven studies showed a significant reduction in hospital readmissions while four did not exhibit any significant reduction. Among the teach-back communication group (6 out of 17), the majority of the studies (5 out of 6) showed a significant reduction in hospital readmissions while one publication did not elicit a significant hospital readmission reduction. mHealth and teach-back communication methods showed positive effects on hospital readmission reduction. These interventions can be utilized in resource-constrained settings, especially low- and middle-income countries, to reduce preventable readmissions.

Abstract
Laparoscopic cholecystectomy has rapidly become the procedure of choice for the treatment of calculus cholecystitis for having clear advantage over open method in reducing surgical morbidity, postoperative pain and complication. But still patients undergoing laparoscopic cholecystectomy complain of considerable pain especially on first post-operative day necessitating use of better methods for postoperative analgesia. This quasi experimental study was done in Surgery Unit III, Mymensingh Medical College Hospital from July 2016 to June 2017 to assess the role of intraperitoneal normal saline instillation following laparoscopic cholecystectomy in relieving postoperative pain. In this study total 200 patients of calculus cholecystitis were enrolled according to inclusion and exclusion criteria and assigned equally into two groups by non-equivalent control group design. Both the control group and experimental group were managed according to the standard protocol and operated in routine operation theater. The experimental group (n=100) was additionally instilled with 25-30ml/kg body weight of normal saline at 37°C at the gallbladder bed and subdiaphragmatic space at the end of surgery and all the data were recorded in individual case record form. Among the sample most of the patients were between 25-60 years of ages with the peak age being between 43-51 years. Eighty one percent (81%) of the total patients were female with male female ratio being 1:5.25 in Control group and 1:3.54 in Experimental group. The VAS scores for visceral pain in experimental group were significantly less than that of control group at 6 hours (p<0.001), 12 hours (p<0.001), 24 hours (p<0.001) and 48 hours (p=0.026). The VAS scores for shoulder tip pain in experimental group were also significantly less than that of control group at 6 hours (p<0.001), 12 hours (p<0.018) and 24 hours (p=0.004). The administration of analgesics was also significantly less in the experimental group than in control group at 6 hours (p<0.001), 12 hours (p<0.001), 24 hours (p=0.313) and 48 hours (p=0.297) with no significant differences at 72 hours. The mean hospital stay in this study was 2.2±0.7 days in the control group and 2.1±0.8 days in the experimental group showing no significant difference (p>0.05). Intraperitoneal normal saline instillation following laparoscopic cholecystectomy may be an eminent choice for reducing postoperative pain improving patient's experience.

Abstract
Genotyping can be used to identify rare blood group antigens and to solve suspected blood group discrepancies, particularly when serologic methods are limited. Unfortunately, only a few such studies have been performed in Pakistan. The present study was conducted to determine the frequency of Dombrock blood group alleles by genotyping samples from blood donors from the north of Pakistan. Blood samples were taken with consent from 300 blood donors; DNA was extracted and tested for DO*01 and DO*02 alleles by sequence-specific primer polymerase chain reaction (PCR-SSP), followed by gel electrophoresis. Allele frequencies were calculated. The observed and expected genotype frequencies were compared using the χ2 test. The allele frequencies for DO*01 and DO*02 were 0.40 and 0.60, respectively. Genotype frequencies were in Hardy-Weinberg equilibrium. This study in Pakistani blood donors provides Dombrock blood group allele frequencies by PCR-SSP. This approach is efficient and economical and can be applied in developing countries. The findings can contribute to the development of in-house red blood cell panels, identification of rare blood types, and establishment of a national rare blood donor program.

Abstract
Staphylococcus aureus is an important foodborne pathogen associated to food intoxication and other multiple infections in human being. Its presence in salted food is a serious issue due to its salt tolerance potential. A study was conducted to analyze the presence of enterotoxins producing drug resistance S. aureus in salted sea fish from Gwadar. Freshly persevered samples (n=50) of salted fish were subjected to analyze the presence of S. aureus using 16S rRNA and Nuc genes primers. The isolates were then evaluated for drug resistance and enterotoxins producing potential using specific primers for MecA (methicillin resistance gene), (SEA) staphylococcal enterotoxin A and (SEB) staphylococcal enterotoxin B genes. Total 13/50 (26%) of the samples were found positive for the presence of S. aureus, preliminary confirmed with biochemical profiling and finally with the help of target genes presence. The isolates were found showing 100% resistant to methicillin, which were molecularly confirmed by the presence of MecA gene present in genome. The isolates 5/13 (38%) were positive for SEA and 3/13 (23%) for SEB genes, whereas 2/13 (15%) were confirmed having both SEA and SEB genes in its genome. It was also confirmed that all the isolates were capable to form biofilm over the glass surfaces. It was concluded that the study confirmed the presence of enterotoxigenic methicillin resistance Staphylococcus aurous (MRSA) in salted fish product, that poses gross food safety concern. Preventive and control measures are necessary to handle this serious food safety concern.
