Navigating undergraduate medical education: a comparative evaluation of a fully online versus a hybrid model.

BACKGROUND: The evaluation of undergraduate medical curricula plays a crucial role in ensuring effectiveness and helps in continuous improvement of the learning process. This study aims to compare the effectiveness of online and hybrid teaching models of the first-year MBBS curriculum in the COVID-19 era (2019-20) and the para-COVID-19 pandemic (2020-21). STUDY METHODOLOGY: Mixed methods study with CIPP model was used. Data was collected by administering a survey and focus group discussions (FGDs) with first-year students from the 2019-2020 and 2020-2021 cohorts, faculty and administrators, which were recorded for analysis. Recorded lectures, guidebooks, planners, and question papers were also scrutinized for quality and adequacy. Furthermore, admission merit, module assessments, and professional examination results were compared and correlated. The learning environment was evaluated through the questionnaire (validated and used by Pakistan Medical and Dental council for inspections of medical schools) and the facilities provided in both years were juxtaposed. The study utilized NVIVO for qualitative and SPSS version 23 for quantitative data analysis. RESULTS: Contextual analysis underscored the critical need for online teaching during the COVID-19 pandemic, with provided resources being deemed sufficient. Notably, the student-faculty ratio stood at 4:1, and essential resources were readily available. The fully online batch outperformed the hybrid teaching class in 2020-21. Process analysis revealed successful session delivery in hybrid and online through webinars and Zoom, accompanied by timely provision of study guides and punctual assessments. Moreover, examination papers demonstrated acceptable reliability (Cronbach's alpha: 0.61) in core subjects. Product analysis indicated that the 2020-21 cohort performed better in modular and professional examinations across all subjects (P < 0.01) despite their lower admission merit compared to the 2019-20 batch. CONCLUSIONS: The study revealed challenges faced during total online teaching, highlighting knowledge and skills gaps in students. While students favored hybrid teaching for interaction, faculty preferred online strategies and suggested blended learning. The administration recognized faculty's swift transition but stressed the need for blended learning workshops and strengthening the medical education department. Recommendations include implementing blended learning strategies, conducting faculty workshops, equipping the medical education department for online teaching, and gathering student feedback after each module to enhance the curriculum.

Evaluating an immunization carpool service for women in rural areas for facilitating routine childhood immunizations in Pakistan -a feasibility study on acceptability, demand, and implementation.

Introduction: Poor accessibility of immunization services coupled with limited options for transportation and socio-cultural norms that hinder women's mobility are among the key factors contributing to poor immunization coverage in rural areas. We assessed the feasibility and acceptability of establishing a free-of-cost, women-only carpool service for immunization in a rural setting in Pakistan and evaluated its preliminary impact on immunization coverage and timeliness among children. Methods: We conducted a feasibility study in four selected immunization facilities in Shikarpur District, Sindh. A local transport vehicle was hired and branded as an immunization carpool service. Women having un- or under-immunized children aged ≤2 years were invited to visit immunization facilities using carpool vehicles. Information on demographic indicators and service experience was collected. Child immunization details were extracted using the government's provincial electronic immunization registry to estimate immunization coverage and timeliness. Results: Between January and October 2020, six immunization carpool vehicles provided uninterrupted service and transported 2422 women-child pairs, completing 4691 immunization visits. Majority of women reported that the carpool service improved accessibility (99.6%) by offering group travel (82.9%) and reducing their dependency on family members (93.4%). Preliminary estimates reported an increase in immunization coverage and timeliness across antigens among participating children compared to non-participating children, with significant increase in proportion for BCG coverage (38.1%; p < 0.001, CI: 32.8%, 43.4%) and measles-2 timeliness (18%; p < 0.001, CI: 13.3%, 22.4%). Conclusion: A women-only immunization carpool service implemented within a rural setting is feasible and highly acceptable. Key factors contributing to the model's success include increased mobility and independence of women, cost-savings, and a culturally and contextually appropriate mechanism of transport embedded within the local setting. Increased accessibility to health services also contributed to improved immunization coverage and timeliness among children.

Predictors for poor daily weight gain in preterm neonates exposed to different dose regimens of caffeine in ICU- a retrospective cohort study.

BACKGROUND: With a wide therapeutic index, efficacy, ease of use, and other neuroprotective and respiratory benefits, caffeine citrate(CC) is currently the drug of choice for preterm neonates (PTNs). Caffeine-induced excessive energy expenditure, diuresis, natriuresis, and other CC-associated potential side-effects (CC-APSEs) result in lower daily-weight gain (WG) in premature neonates. This study aimed to evaluate the risk factors for daily-WG in neonates exposed to different dose regimens of caffeine in ICU. METHOD: This retrospective cohort study included neonates of ≤ 36weeks gestational age (GA) and received CC-therapy. The same participants were followed for data analysis in two postnatal phases: 15-28 and 29-42 days of life (DOL). Based on daily CC-dose, formed group-I (received; standard-doses = 5 mg/kg/day), group-II (received;>5-7 mg/kg/day), and group-III (received;>7 mg/kg/day). Prenatal and postnatal clinical characteristics, CC-regimen, daily-WG, CC-APSEs, and concomitant risk-factors, including daily-caloric intake, Parenteral-Nutrition duration, steroids, diuretics, and ibuprofen exposure, were analyzed separately for group-II and group-III using group-I as standard. Regression analysis was performed to evaluate the risk factors for daily-WG. RESULTS: Included 314 PTNs. During 15-28 DOL, the mean-daily-WG(MD-WG) was significantly higher in group-I than group-II [19.9 ± 0.70 g/kg/d vs. 17.7 ± 0.52 p = 0.036] and group-III [19.9 ± 0.70 g/kg/d vs. 16.8 ± 0.73 p < 0.001]. During 29-42 DOL the MD-WG of group-I was only significantly higher than group-III [21.7 ± 0.44 g/kg/d vs. 18.3 ± 0.41 g/kg/d p = 0.003] and comparable with group-II. During 15-28 DOL, observed CC-APSEs was significantly higher in group-II and III but during 29-42 DOL it was only significant in group-III. In the adjusted regression analysis for daily-WG during 15-28DOL, with respect to standard-dose, 5-7 mg/kg/day (ß=-1.04; 95%CI:-1.62,-0.93) and > 7-10 mg/kg/day (ß=-1.36; 95%CI:-1.56,-1.02) were associated with a lower daily-WG. However, during 29-42DOL, this association was present only for > 7-10 mg/kg/day (ß=-1.54; 95%CI:-1.66,-1.42). The GA ≤ 27weeks (ß=-1.03 95%CI:-1.24, -0.88) was associated with lower daily-WG only during 15-28DOL. During both periods of therapy, higher cumulative-caffeine dose and presence of culture proven sepsis, tachypnea, hyponatremia, and feeding intolerance were significantly associated with lower daily-WG. Conversely, daily kcal intake was found to be linked with an increase in daily-WG in both periods. CONCLUSION: In this study cohort exposure to higher caffeine daily and cumulative doses is associated with lower postnatal daily-WG in PTNs than standard-daily doses, which may be due to its catabolic effects and CC-APSEs.

MBBS admission criteria as predictor of academic performance in a medical college of Pakistan.

Objective: To determine the relationship between scores obtained by students in assessments considered as admission criteria (cognitive and non-cognitive) with their academic performance in medical college. Method: This correlational study used the data of students who got admission in Shalamar Medical and Dental College (SMDC) in 2015. Spearman correlation and Multiple regression tests were carried out to determine the relationship between admission criteria (Matric, FSC, MDCAT and MMI) and academic performance in medical college (pre-clinical and clinical years). Results: There was significant positive correlation between scores obtained in MDCAT and pre-clinical years. When combined, MDCAT and MMI scores showed a significant positive correlation with scores obtained by students in clinical years. Scores obtained by students in pre-clinical years strongly correlated with their performance in clinical years. While scores obtained by students in FSC showed negative correlation with clinical year scores, significantly. Conclusion: It is concluded that the tools used for admission criteria should include both cognitive and non-cognitive elements. MDCAT is a good predictor of academic performance in pre-clinical years however it can only predict performance in clinical years when combined with MMI since MMI assesses the non-cognitive attributes (communication, empathy, ethics etc.) required in those years. FSC should not be given weightage as admission criteria owing to a lot of variability in the exams and scoring of different academic boards of the country.

Barriers and Facilitators for Female Healthcare Professionals to Be Leaders in Pakistan: A Qualitative Exploratory Study.

Purpose: Despite being in high numbers in medical colleges, only a small proportion of women join the workforce and even fewer reach leadership positions in Pakistan. Organizations like United Nations and Women Global Health are working towards closing the gender gap. The study aims to explore the enablers and barriers for women in healthcare leadership and to explore the strategies to promote women in leadership positions in Pakistan's specific societal culture. Methods: In this qualitative exploratory study, semi-structured interviews of 16 women holding leadership positions in the health-care profession, ie, medical and dental (basic or clinical sciences) were included. The data were collected until saturation was achieved. The data were analyzed in MS Excel. Deductive and Inductive thematic analysis was done. Results: Thirty-eight codes were generated that were combined in the form of categories. The major themes that emerged from the data were: elevating factors, the shackles holding them back, let us bring them up and implicit bias. Elevating factors were intrinsic motivation and exceptional qualifications, while the shackles were related to gender bias, male insecurities, and lack of political background. It was noteworthy that differences in gender roles were highly defined by culture and religion. Conclusion: There is a need to change the perception of South Asian society and redefine gender roles through media and individual attempts. Women must take charge of their choices and believe in themselves. The institutional policies to help promote gender equality would be mentorship programs for new faculty, gender-responsive training for everyone, equal opportunities for all, and maintaining gender diversity on all committees.

Using geographic information system to track children and optimize immunization coverage and equity in Karachi, Pakistan.

BACKGROUND: Despite the potential of geospatial technologies to track and monitor coverage, they are underutilized for guiding immunization program strategy and implementation, especially in low-and-middle-income countries. We conducted geospatial analysis to explore the geographic and temporal trends of immunization coverage, and examined the pattern of immunization service access (outreach and facility based) by children. METHODOLOGY: We extracted data to analyze coverage rates across different dimensions (by enrolment year, birth year and vaccination year) from 2018 till 2020 in Karachi, Pakistan using the Sindh Electronic Immunization Registry (SEIR). We conducted geospatial analysis to assess variation in coverage rates of BCG, Pentavalent (Penta)-1, Penta-3, and Measles-1 vaccines using Government targets. We also analyzed the proportion of children receiving their routine vaccinations at fixed centers and outreach and examined whether children received vaccinations at the same or multiple immunization centers. RESULTS: A total of 1,298,555 children were born, enrolled or vaccinated from 2018 till 2020. At the district level, analysis by enrollment and birth year showed coverage increased between 2018 and 2019 and declined in 2020, while analysis by vaccination year showed consistent increase in coverage. However, micro-geographic analysis revealed pockets where coverage persistently declined. Notably 27/168, 39/168 and 3/156 Union councils showed consistently declining coverage when analyzing by enrollment, birth and vaccination year respectively. More than half (52.2%, 678,280/1,298,555) of the children received all their vaccinations exclusively through fixed centers and, 71.7% (499,391/696,701) received all vaccinations from the same centers. CONCLUSION: Despite overall improving vaccination coverage between 2018 and 2020, certain geographic areas have consistently declining coverage rates, which is detrimental for equity. Making immunization inequities visible through geospatial analysis is the first step to ensure resources are allocated optimally. Our study provides impetus for immunization programs to develop and invest in geospatial technologies, harnessing its potential for improved coverage and equity.

Immunization Gender Inequity in Pakistan: An Analysis of 6.2 Million Children Born from 2019 to 2022 and Enrolled in the Sindh Electronic Immunization Registry.

Gender-based inequities in immunization impede the universal coverage of childhood vaccines. Leveraging data from the Government of Sindh's Electronic Immunization Registry (SEIR), we estimated inequalities in immunization for males and females from the 2019-2022 birth cohorts in Pakistan. We computed male-to-female (M:F) and gender inequality ratios (GIR) Tfor enrollment, vaccine coverage, and timeliness. We also explored the inequities by maternal literacy, geographic location, mode of vaccination delivery, and gender of vaccinators. Between 1 January 2019, and 31 December 2022, 6,235,305 children were enrolled in the SEIR, 52.2% males and 47.8% females. We observed a median M:F ratio of 1.03 at enrollment and at Penta-1, Penta-3, and Measles-1 vaccinations, indicating more males were enrolled in the immunization system than females. Once enrolled, a median GIR of 1.00 indicated similar coverage for females and males over time; however, females experienced a delay in their vaccination timeliness. Low maternal education; residing in remote-rural, rural, and slum regions; and receiving vaccines at fixed sites, as compared to outreach, were associated with fewer females being vaccinated, as compared to males. Our findings suggeste the need to tailor and implement gender-sensitive policies and strategies for improving equity in immunization, especially in vulnerable geographies with persistently high inequalities.

Development of a tool for objectively measuring somatic pain in the low back region based on a longitudinal diagnostic study conducted in Karachi, Pakistan.

OBJECTIVES: This study aimed at devising an objective method for quantifying pain in the low back region using pressure pain threshold (PPT) and demographic factors as predictive variables. METHODS: The research was conducted in two phases. Phase I was a longitudinal exploratory study conducted on 49 men aged 18-50 years with chronic low back pain (CLBP) recruited using non-probability purposive sampling. We used Visual Analogue Scale to record pain intensity and pain affect, and Disability Rating Index to record associated disability. PPT was measured on 12 different locations on the lower back using a manual algometer. These measurements were taken from each participant in 1 to 6-follow-up visits, depending on improvement in the individual's symptoms. In phase II additional 33 subjects, both men and women with varying durations of low back pain were recruited using non-probability convenience sampling. Repeated measures ordinal regression and receiver's operating characteristic curve analyses were performed to develop predictive models using STATA V.16.0 and R V.3.5.2 software. These models were given an interface using Microsoft Excel. A p value of <0.05 was considered statistically significant. RESULTS: Higher PPT scores, increased lean body mass, lean physique and a longer duration of CLBP were associated with a reduction in CLBP intensity, affect and disability. Advancing age was associated with an increase in these outcomes. Collectively, these factors were found to predict pain intensity, affect, and disability with 63%-65% diagnostic accuracy in phase I, however, this diagnostic accuracy increased to 65%-78% in phase II. CONCLUSION: We developed a new outcome tool 'Pain Calculator' that can objectively measure low back pain with sufficient statistical accuracy. With further refinement, this tool in the future can be configured to measure somatic pain in different regions as well, affording clinicians and researchers much-needed objectivity while recording pain levels. TRIAL REGISTRATION NUMBER: NCT04482075.

Is Tocilizumab An Effective Therapy For Severe Covid-19: A Single Center Study.

Background: The quest for effective therapies in Covid-19 continues. We compared the outcome of severe COVID-19 patients treated with and without Tocilizumab, an IL-6 inhibitor. Methods: This is a prospective cohort study on the clinical characteristics and outcomes of patients with Covid-19 patients admitted at The Indus Hospital and Health Network, Karachi between 24th March and 19th June 2020. Adult patients who received TCZ were compared with respect to mortality and days of hospitalization with those who did not. Results: A total of 88 patients including 41 patients in the TCZ group and 47 in non-TCZ group were recruited. Baseline demographic characteristics were comparable. TCZ group patients presented with worse clinical features including median SpO2 82% vs 88%, p<0.05 and CRP 193 vs 133.9 mg/L, p<0.05. Approximately, 85.4% were admitted in ICU compared to 69.8% in non-TCZ group, p>0.05. Mortality was not different among the groups (46% in TCZ group vs 51.1% in non-TCZ group, p>0.05). Median length of hospital stays, days of intubation, use of inotropic agents, and use of invasive ventilation or in-hospital complications were similar between the groups. Sub-group analysis revealed that mortality within TCZ group was associated with high IL-6 levels (173 vs 69.66 pg/ml, p<0.05), ICU admission (100% vs 72%, p<0.05), need for mechanical ventilation (100% vs 13.6%, p<0.05) and higher incidence of in-hospital complications, p<0.05. Conclusion: TCZ failed to demonstrate any mortality benefit in our patients. Non-survivors within the TCZ group were more critical compared to survivors and developed more in hospital complications.

Experiences of medical and dental students of Pakistan during COVID-19 pandemic lockdown: a qualitative study.

OBJECTIVE: The COVID-19 pandemic resulted in medical institutes being shut down. Face-to-face activities were shifted to online medium. The unpredictability of the situation impacted medical faculty and students alike, creating panic and anxiety. Since these students are to take hold of the healthcare system of the country soon, it is important to learn their perspective on how COVID impacted them. Therefore, this study aimed to explore the lived experiences of Pakistani medical students in-depth by a qualitative observation of their personal and educational experiences. DESIGN: A phenomenological qualitative study interviewing medical students of Pakistan was conducted. PARTICIPANTS/METHODOLOGY: This study was designed to interview medical and dental students from various cities in Pakistan using a semistructured, open-ended questionnaire. A total of 34 interviews were recorded and transcripts were prepared. All authors (SI, SS, IA and MS) were involved in the thematic analysis of the data, whereby transcripts were read thoroughly, and codes were developed. Similar codes were then combined to generate themes. RESULTS: Three major themes emerged after the analysis of results. The students' 'diverse experiences' of panic and anxiety or excitement were high initially but gradually reduced as time progressed. The 'unprecedented academic experiences' of students included teaching/learning, communication and technical challenges that they faced during online classes. Despite facing a lot of challenges, the students still saw 'light at the end of the tunnel' and looked forward to going back to their college. CONCLUSION: The effects of COVID on the physical, psychological, social and academic life of medical students were enormous. It is highly recommended that institutes and faculty provide support for personal and professional development of students in these unprecedented times in the form of counselling, provision of technical facilities or leniency in fee process. Peer support is also considered crucial in reducing anxiety among students.

Diagnostic accuracy of C-reactive protein to rule out infectious complications following hip fracture surgery.

Background and Objective: Knowledge of the C-reactive protein trend and deviation from the expected value may give an early indication of a possible postoperative infection. According to previous studies, CRP appears to be a more sensitive and specific marker of postoperative infections than ESR and white cell count. This study was conducted to determine the diagnostic accuracy of C-reactive protein to rule out surgical site infection in patients undergoing hip fracture surgery. Methods: This cross-sectional study was conducted at The Indus Hospital and Health Network, Karachi from July 1, 2018 to February 24, 2020. All operative hip fracture patients aged 11-90 years were included. CRP was done on admission, days 3, 14 and 28. Wound assessment was done using the criteria of the Center of Disease Control and prevention on postoperative days 3, 14 and 28. Data was analyzed using STATA version 16. Results: Out of 152 patients, 11(7.2%) developed infection. One patient (0.7%) presented with the infection on day three post-surgery, eight (5.3%) and two (1.3%) patients on days 14 and 28 respectively. CRP levels at admission had poor diagnostic accuracy for diagnosing infection at 14th and 28th day post-surgery respectively (AUC=0.490 and 0.447). CRP levels measured on post-op Day-3 (cutoff value 230mg/dl) had good diagnostic accuracy for diagnosing infection at 14th and 28th day post-surgery respectively (AUC=0.819 and 0.818). Conclusion: CRP level at post-operative day three is a sensitive indicator of infection after hip fracture surgery.

Prevalence, geographical distribution and factors associated with pentavalent vaccine zero dose status among children in Sindh, Pakistan: analysis of data from the 2017 and 2018 birth cohorts enrolled in the provincial electronic immunisation registry.

OBJECTIVES: To estimate the prevalence of zero dose children (who have not received any dose of pentavalent (diphtheria, tetanus, pertussis, Haemophilus influenzae type B and hepatitis B) vaccine by their first birthday) among those who interacted with the immunisation system in Sindh, Pakistan along with their sociodemographic characteristics and risk factors. DESIGN AND PARTICIPANTS: We conducted a descriptive analysis of child-level longitudinal immunisation records of 1 467 975 0-23 months children from the Sindh's Zindagi Mehfooz (Safe Life) Electronic Immunisation Registry (ZM-EIR), for the birth cohorts of 2017 and 2018. SETTING: Sindh province, Pakistan which has a population of 47.9 million people and an annual birth cohort of 1.7 million. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome measure was zero dose status among enrolled children. Logistic regression was performed to identify the risk factors associated with the zero dose status. RESULTS: Out of 1 467 975 children enrolled in the ZM-EIR in Sindh, 10.6% (154 881/1 467 975) were zero dose. There were sharp inequities across the 27 districts. Zero dose children had a lower proportion of hospital births (28.5% vs 34.0%; difference 5.5 percentage points (pp) (95% CI 5.26 to 5.74); p<0.001) and higher prevalence from slums (49.5% vs 42.3%; difference 7.2 pp (95% CI 6.93 to 7.46); p<0.001), compared with non-zero dose children. Children residing in urban compared with rural areas were at a higher risk (relative risk (RR): 1.20; p<0.001; 95% CI 1.18 to 1.22), while children with educated compared with uneducated mothers were at a lower risk of being zero dose (RR: 0.47-0.96; p<0.001; 95% CI 0.45 to 0.98). CONCLUSIONS: Despite interacting with the immunisation system, 1 out of 10 children enrolled in the ZM-EIR in Sindh were zero dose. It is crucial to monitor the prevalence of zero dose children and investigate their characteristics and risk factors to effectively reach and follow-up with them.

Eight-year Review of a Clubfoot Treatment Program in Pakistan With Assessment of Outcomes Using the Ponseti Technique: A Retrospective Study of 988 Patients (1,458 Clubfeet) Aged 0 to 5 Years at Enrollment.

OBJECTIVE: To conduct an 8-year retrospective review of a clubfoot treatment program using the Ponseti technique with close monitoring of outcomes. METHODS: Between October 2011 and August 2019, 988 children with 1,458 idiopathic clubfeet were enrolled, ages ranging from new born up to 5 years. Ponseti treatment was used, and progress was monitored by comparing mean Pirani scores at enrollment (P1), initiation of bracing (P2), and end of treatment (P3) or most recent visit (P4) for children under treatment. RESULTS: A statistically significant reduction in Pirani scores was noted (P < 0.001) for all feet. For 320 feet completing treatment (213 children), the mean Pirani scores reduced from P1: 3.8 (±1.1) to P2: 1.1 (±0.6) and finally to P3: 0.6 (±0.3). Four hundred sixteen children are currently undergoing bracing. Higher education of the head of household and male sex of the child were markedly associated with improved outcomes in foot correction status. Correction was obtained with a mean of 5.8 casts per foot, the tenotomy rate was 68.2%, and the mean duration of bracing in children completing treatment was 3.6 years (±0.9). No surgical correction, other than tenotomy, was required. Relapse was noted in 12.1% of the total enrolled feet, and 32.0% children were lost to follow-up from the entire cohort of 988 children. CONCLUSION: Clubfoot treatment requires long-term follow-up. A dedicated clubfoot program is effective in maintaining continuity of care by encouraging adherence to treatment.

Inducting undergraduate medical students via WhatsApp-based multiple mini interviews during COVID-19 pandemic.

Selection of medical students requires both cognitive and soft skills assessment. Shalamar Medical and Dental College (SMDC) has been using on-campus multiple mini interviews to assess the latter but due to Covid-19 pandemic it became imperative that an alternative be found. The aim of this communication is to share the process SMDC went through to plan, design, and ultimately conduct WhatsApp-based multiple mini interviews (wMMI) in a low risk method as an entry criteria for undergraduate medical students. The process involved designing scenarios appropriate for online interviews, training the faculty members regarding conducting MMI as well as the use of technology, and designing an online webpage for enrolling, scheduling and assessing candidates. We were able to successfully complete wMMI process for 522 candidates within one week in a low risk setting using WhatsApp as communication medium with strong IT and administrative support.

Sensitivity and Specificity of Anti-SARS-CoV-2 Detection Kits - Comparison and Agreement between Fifteen Different Assays.

Accurate and rapid diagnosis of coronavirus disease 2019 (COVID-19) is critical for proper care and identification of affected individuals. This led to early availability of many serological assays in the market, but with limited validation. In this study, we aimed to validate the serological assays based on different techniques. We evaluated 15 different assays based on four immunoassay techniques in 235 patients. The most sensitive kits employed were as follows: immunochromatography (Zybio severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2] IgM/IgG Antibody Assay Kit - 83%), ELISA (Aeskulisa SARS-CoV-2 NP IgG -88.1%), chemiluminescence (Alinity SARS-CoV-2 IgG - 82.2%), and immunofluorescence (Lifotronic FA160 (Shenzhen SARS-CoV-2 Assay Kit [IgG]) - 88.9%). The kits by Uniper (Singuway Biotec COVID-19 IgM/IgG Presumptive Kit), Genrui 2019-nCoV IgM/IgG Test Kit, Wondfu SARS-CoV-2 Antibody Test, and Aeskulisa SARS-CoV-2 NP IgG exhibited 100% specificity, whereas IgG assay using Lifotronic FA160 (Shenzhen SARS-CoV-2 Assay Kit) exhibited the lowest specificity at 58%. Maximum agreement was observed between Aeskulisa SARS-CoV-2 NP IgG and Alinity SARS-CoV-2 IgG at 94%. Serological tests are practical alternatives, but their reliability depends on critical validation. The COVID-19 pandemic warranted investment in healthcare research at both the national and international levels.

The trends of dental biomaterials research and future directions: A mapping review.

OBJECTIVE: This literature research aimed to compare, contrast and quantify the innovations in the most commonly used dental biomaterials. METHODOLOGY: Original research articles based on experimental dental biomaterials published between 2007 and 2019 were retrieved and reviewed. A search of electronic databases, PubMed, Scopus, and Web of Science indexed dental/biomaterials journals, has been conducted. The inclusion criteria in this research were: synthesis of experimental dental materials, whereas commercial dental materials, review articles, and clinical trials (case reports) were excluded. RESULTS: It was found that the amount of publications related to dental subgingival implants, computer-aided modeling ceramics, aesthetic restorative materials, adhesives cements, ceramics, bioceramics, endodontic materials, bioactive scaffolds, stem cells, and guided-tissue membranes had increased significantly from 2007. At the same time, the number of publications related to dental cements, silver amalgam, and dental alloys has decreased. For characterization of dental materials it was noted that mechanical properties were tested mostly for restorative materials. On the other hand, biological properties were most assessed for dental subgingival implants and endodontic materials, however, physical properties predominantly for bioceramics. CONCLUSION: It is concluded that to meet clinical demands there was more focus on restorative materials that provided better aesthetics, including resin composites, adhesive resin composites (luting cements), zirconia, and other ceramics. The boost in laboratory and animal research related to bioceramics was attributed to their regenerative potential. This current literature study will help growing researchers to consider and judge the direction to which research might be guided in order to plan prospective research projects.

Impact of hand hygiene intervention on hand washing ability of school-aged children.

BACKGROUND: To assess the current knowledge related to hand washing and efficiency of intervention on hand washing techniques amongst school children. METHODOLOGY: A randomized control trial was conducted amongst class II students of a private school in Korangi, Karachi. Pre-intervention assessment including baseline knowledge and observed practices of hand washing in comparison with World Health Organization (WHO) standard hand washing techniques was done. This was followed by education and demonstration of proper hand washing steps by principal investigator utilizing visual aids. Participants were then randomized into two group: Group A (education only group) and Group B (education along with glow gel application group). First post-intervention assessment was conducted on same day where both groups were observed for the hand washing steps and scored for hand washing technique. In addition, participants of group B were shown germs under Ultraviolet (UV) light. School was revisited after 1 week later and participants were reassessed for their hand washing technique along with cleanliness grade after applying glow gel and observing under UV light. Data was entered and analyzed using SPSS version 21.0. RESULT: No significant differences were found in median hand washing scores pre-intervention between both the groups (Group A vs B: 4 vs 5, P value = 0.659), while significant improvement in median hand washing scores was seen post intervention in group B as compared to group A (7 vs 6, P value = 0.011). However, no significant differences were seen in median hand washing scores at follow-up between both the groups (Group A vs B: 9 vs 8.5, P value = 0.715) but a significant improvement was observed in both the groups in the hand washing practices from baseline (P-value = 0.000). On the contrary, no significant differences were found in median cleanliness grade between both the groups (Median for both the groups was 5, P value = 0.695). CONCLUSIONS: Hand washing education utilizing various aids is an effective method to improve children's hand washing capability. This short-term intervention was effective even in absence of glow gel, but no cleanliness of hands was observed in both the groups.

Parental perception on screen time and psychological distress among young children.

OBJECTIVE: We aimed to assess the parent-reported screen time of children, identify the perceived risk factors for increased screen time and its relationship to psychological distress in children. MATERIALS AND METHOD: A cross sectional study was conducted at a teaching hospital in Karachi, Pakistan. A total of 230 employees from medical and non-medical departments were included. Participants were employees with child/children ages 4-12 year who consented to participate in the study, we included 135 fathers and 91 mothers. The questionnaire included (i) demographic data (ii) Media history exam form and (iii) parent reported strength and difficult questionnaire (SDQ). RESULT: The average daily screen time reported was 2.5 (1.5-5) hour for boys and 2 (1-4) hour for girls. Preschoolers had greater screen time as compared to school-aged children (Median (IQR): 3 (1.5-5.6) vs 2 (1-4), P = 0.46). The children owned devices with approximately equal distribution of preschoolers and school-aged children (19 (27.1%) and 48 (30%), P = 0.661 respectively). Emotional score was found higher in school-aged group in comparison to preschoolers (p = 0.036). Moreover, mother screen time and number of devices owned by a child were found to be positively associated with child's screen time. CONCLUSION: We conclude that as we are embracing the digital age providing a tech free zone to children is virtually impossible. Children screen time related activities in our part of the world exceeds the limitation. Parental awareness and co-viewing screen with their children are essential to avoid media related behavior problems.

Self-medication among people visiting outpatient clinics of a Tertiary care hospital, Karachi.

BACKGROUND AND AIM: "Self-medication" is the self-use of medicines for treatment of illnesses. Inappropriate use of medicines without prescription leads to unwanted adverse effects, harmful drug interactions, and antibiotic resistance which is an emerging concern in developing countries due to escalating burden of infectious diseases. This study aims at identifying the frequency and contributing factors of self-medication, nature of illness, and types of medicines used without doctor's prescription. MATERIAL AND METHODS: This cross sectional study was conducted at Indus Hospital Karachi between March 2017 and December 2018. Two hundred and forty people of any age visiting the outpatient clinics of the Indus hospital consenting to participate were included. Whereas all clinicians including medical officers, specialists and consultants were excluded from the study. RESULTS: Three-fifth (n = 147; 61.3%) of the participants reported that they did self-medication either for themselves or for their children in the past one year. The most common symptoms for which self-medication was done were fever (n = 82, 55.8%), cough/cold (n = 38; 25.8%) or diarrhea (n = 22; 15.0%). Out of which, 122 (83%) did self-medication based on their previous experience, 18 (12.2%) used previous doctor's prescriptions, whereas 22 (15%) reported that other people advised them. Education, presence of unused medicines at home, and those who have heard of antibiotic were found to be the significant risk factors associated with self-medication. CONCLUSION: Among Pakistani population, the frequency of self-medication is very high, with most people practicing self-medication on the basis of their previous experiences. It puts them at risk of experiencing adverse reactions and most importantly antibiotic resistance.

Implementation of an infant male circumcision programme, Pakistan.

OBJECTIVE: To retrospectively review outcomes of a health provider-led infant circumcision programme in Pakistan. METHODS: Based on World Health Organization guidelines, we trained surgical technicians and midwives to perform circumcisions using the Plastibell device at two Indus Health Network facilities. Programme tools include a training manual for health providers, information brochures for families, an enrolment form and standardized forms for documenting details of the procedure and outcomes. Infants aged 1-92 days were eligible for the study. Health workers contacted families on days 1 and 7 after the procedure to record any adverse events. We compared the characteristics of infants experiencing adverse events with infants facing no complications using multivariate logistic regression. FINDINGS: Between August 2016 and August 2018, 2822 circumcised male infants with mean age 22.8 days were eligible for the study. Of these, 2617 infants (92.7%) were followed up by telephone interviews of caretakers. Older infants were more likely to experience adverse events than infants circumcised between 1-30 days of age: 31-60 days: adjusted odds ratio, aOR: 2.03; 95% confidence interval, CI: 1.31-3.15; 61-92 days: aOR: 2.14; 95% CI: 1.13-4.05. Minor adverse events (100 infants; 3.8%) included failure of the bell to shed (90 infants) and minimal bleeding (10 infants). Major adverse events (eight infants; 0.3%) included bleeding that required intervention (four infants), infection (three infants) and skin tear (one infant). CONCLUSION: Standardized training protocols and close monitoring enabled nonphysician health providers to perform safe circumcisions on infants aged three months or younger.
