    Vaccine hesitancy (VH) is not a new phenomenon in Pakistan and is regarded as one of the primary causes of unsatisfactory vaccination campaigns. This study determined post-vaccination COVID-19 VH, factors influencing COVID-19 vaccine uptake, and public's intent to receive booster vaccinations. A cross-sectional study was conducted among adult population of Lahore, Pakistan. Participants were recruited via convenience sampling between March and May 2022. SPSS version 22 was used for the data analysis. A total of 650 participants were included in the study (age = 28.1 ± 9.7 years; male-to-female ratio nearly 1: 1). The majority of participants received Sinopharm followed by Sinovac vaccine. The top three reasons of vaccine uptake were "only vaccinated individuals are allowed at the workplace, and educational institutes" (Relative importance index (RII) = 0.749), "only vaccinated people are allowed to go to markets, malls and other public places" (RII = 0.746), and "protect myself from the infection" (RII = 0.742). The mean COVID-19 VH score was 24.5 ± 6.2 (95% CI 23.9-24.9), with not being pro-vaccines and poor economic status were the significant predictors of COVID-19 vaccine hesitancy among immunized individuals (p

    Despite myriad improvements in the care of COVID-19 patients, atypical manifestations are least appreciated during the current pandemic. Because COVID-19 is primarily manifesting as an acute respiratory illness with interstitial and alveolar pneumonia, the possibility of viral invasions into the other organs cannot be disregarded. Acute kidney injury (AKI) has been associated with various viral infections including dengue, chikungunya, Zika, and HIV. The prevalence and risks of AKI during the course of COVID-19 have been described in few studies. However, the existing literature demonstrate great disparity across findings amid variations in methodology and population. This article underscores the propensity of AKI among COVID-19 patients, limitations of the exiting evidence, and importance of timely identification during the case management. The prevalence of AKI is variable across the studies ranging from 4.7% to 81%. Evidence suggest old age, comorbidities, ventilator support, use of vasopressors, black race, severe infection, and elevated levels of baseline serum creatinine and d-dimers are independent risk factors of COVID-19 associated with AKI. COVID-19 patients with AKI also showed unsatisfactory renal recovery and higher mortality rate as compared with patients without AKI. These findings underscore that AKI frequently occurs during the course of COVID-19 infection and requires early stratification and management.

    BACKGROUND: Despite myriad improvements in the care of dengue patients, acute kidney injury (AKI) remained least appreciated intricacy of dengue infection. Exiting literature does not provide any information on renal outcomes among dengue patients surviving an episode of AKI.

    METHODS: Dengue patients who developed AKI were followed up for post-discharge period of three months and renal recovery was assessed by using recovery criteria based on different thresholds of serum creatinine (SCr) and estimated glomerular filtration rates (eGFR).

    RESULTS: Out of the 526 dengue participants, AKI was developed in 72 (13.7%) patients. Renal recovery was assessed among AKI survivors (n = 71). The use of less (±50% recovery to baseline) to more (±5% recovery to baseline) stringent definitions of renal recovery yielded recovery rates from 88.9% to 2.8% by SCr and 94.4% to 5.6% by eGFR, as renal function biomarkers. At the end of study, eight patients had AKI with AKIN-II (n = 7) and AKIN-III (n = 1). Approximately 50% patients (n = 36/71) with AKI had eGFR primitive to CKD stage 2, while 18.3% (n = 13/71) and 4.2% (n = 3/71) patients had eGFR corresponding to advanced stages of CKD (stage 3 & 4). Factors such as renal insufficiencies at hospital discharge, multiple organ involvements, advance age, female gender and diabetes mellitus were associated with poor renal outcomes.

    CONCLUSIONS: We conclude that dengue patients with AKI portend unsatisfactory short-term renal outcomes and deserve a careful and longer follow-up, especially under nephrology care.

    BACKGROUND: Safety and efficacy concerns regarding coronavirus disease 2019 (COVID-19) vaccines are common among the public and have a negative impact on their uptake. We aimed to report the adverse effects currently associated with the vaccine in Pakistan to build confidence among the population for its adoption.

    METHODS: A cross-sectional study was conducted in five districts of the Punjab province of Pakistan between January and March 2022. The participants were recruited using convenience sampling. All data were analyzed using SPSS 22.

    RESULTS: We recruited 1622 people with the majority aged between 25-45 years. Of these, 51% were female, including 27 pregnant women and 42 lactating mothers. Most participants had received the Sinopharm (62.6%) or Sinovac (17.8%) vaccines. The incidences of at least one side effect after the first (N = 1622), second (N = 1484), and booster doses (N = 219) of the COVID-19 vaccine were 16.5%, 20.1%, and 32%, respectively. Inflammation/erythema at the injection site, pain at the injection site, fever, and bone/muscle pain were common side effects of vaccination. No significant differences were observed in the adverse effect scores between all demographic variables except for pregnancy (P = 0.012) after the initial dose. No significant association was observed between any variable and the side effect scores of the second and booster doses of the vaccine.

    CONCLUSIONS: Our study showed a 16-32% prevalence of self-reported side effects after the first, second, and booster COVID-19 vaccinations. Most adverse effects were mild and transient, indicating the safety of different COVID-19 vaccines.

    OBJECTIVE: The aim of this study is to ascertain the psychological impacts of coronavirus disease (COVID-19) among the Pakistani health care workers (HCWs) and their coping strategies.

    METHODS: This web-based, cross-sectional study was conducted among HCWs (N = 398) from Punjab Province of Pakistan. The generalized anxiety scale (GAD-7), patient health questionnaire (PHQ-9), and Brief-COPE were used to assess anxiety, depression, and coping strategies, respectively.

    RESULTS: The average age of respondents was 28.67 years (SD = 4.15), with the majority being medical doctors (52%). Prevalences of anxiety and depression were 21.4% and 21.9%, respectively. There was no significant difference in anxiety and depression scores among doctors, nurses, and pharmacists. Females had significantly higher anxiety (P = 0.003) and depression (P = 0.001) scores than males. Moreover, frontline HCWs had significantly higher depression scores (P = 0.010) than others. The depression, not anxiety, score was significantly higher among those who did not receive the infection prevention training (P = 0.004). The most frequently adopted coping strategies were religious coping (M = 5.98, SD = 1.73), acceptance (M = 5.59, SD = 1.55), and coping planning (M = 4.91, SD = 1.85).

    CONCLUSION: A considerable proportion of HCWs are having generalized anxiety and depression during the ongoing COVID-19 pandemic. Our findings call for interventions to mitigate mental health risks in HCWs.

    AIM: Despite increase global prevalence of End stage renal disease (ESRD) and subsequent need for renal replacement therapy (RRT), relatively little is known about disease progression and prognosis of earlier stages of CKD. Current study was conducted to examine rate of CKD progression, predictors of ESRD and death.

    METHODS: A total 621 patients with estimated glomerular filtration rate (eGFR) of 15-59ml/min/1.73m(2) (CKD stage 3 & 4) were selected and followed up for 10 years or until ESRD or death, whichever occurred first. Subjects who did not meet inclusion criteria were excluded (n=1474).

    RESULTS: Annual cumulative decline in eGFR was 3.01±0.40 ml/min/1.73m(2) . Overall disease progression was observed in 60% patients while 18% died. Among patients with CKD stage 3, 21% progressed to stage 4, 10% to stage 5ND (non-dialysis) and 31% to RRT while mortality was observed in 16% patients. On the other hand, 8% patients with CKD stage 4 progressed to stage 5ND, 31% to RRT and mortality was observed in 24% cases. Patients with CVD, higher systolic blood pressure, elevated phosphate levels, heavy proteinuria, microscopic hematuria and use of diuretics were more likely to develop ESRD. Advancing age, low eGFR, low systolic blood pressure, low hemoglobin and baseline diabetes were found to be significant predictors of mortality while being female reduced risk of mortality.

    CONCLUSION: Our data suggest that, in this CKD cohort, patients were more likely to develop ESRD than death. Prime importance should be given to mild forms of CKD to retard and even reverse CKD progression.

    Chronic kidney disease (CKD) is an asymptomatic disease associated with high morbidity and life-threatening complications that lead to decreased life expectancy. Worldwide prevalence of CKD is escalating at an alarming rate. Large population-based representative surveys have been reported in Western countries to estimate the prevalence of the disease. However, there is paucity of data as far as developing nations are concerned. Asia is the world's largest continent accommodating maximum number of under-developed and developing countries with an unclear picture of prevalence of CKD. Current review attempts to give an insight to the prevalence of CKD in this region by combining population-based surveys. This review will assist in estimating the burden of CKD in Asia, so that appropriate control measures could be designed.

    Healthcare-associated infections (HAIs) have a considerable impact on morbidity, mortality and costs. The COVID-19 pandemic resulted in an appreciable number of hospitalized patients being admitted to intensive care units (ICUs) globally with a greater risk of HAIs. Consequently, there is a need to evaluate predictors and outcomes of HAIs among COVID-19 patients admitted to ICUs. A retrospective study of patients with COVID-19 admitted to ICUs of three tertiary care hospitals in the Punjab province over a five-month period in 2021 was undertaken to ascertain predictors and outcomes of HAIs. Of the 4534 hospitalized COVID-19 patients, 678 were admitted to ICUs, of which 636 patients fulfilled the inclusion criteria. Overall, 67 HAIs were identified among the admitted patients. Ventilator-associated lower respiratory tract infections and catheter-related urinary tract infections were the most frequent HAIs. A significantly higher number of patients who developed HAIs were on anticoagulants (p = 0.003), antithrombotic agents (p < 0.001), antivirals (p < 0.001) and IL-6 inhibiting agents (p < 0.001). Secondary infections were significantly higher in patients who were on invasive mechanical ventilation (p < 0.001), had central venous access (p = 0.023), and urinary catheters (p < 0.001). The mortality rate was significantly higher in those with secondary infections (25.8% vs. 1.2%, p < 0.001). Our study concluded that COVID-19 patients admitted to ICUs have a high prevalence of HAIs associated with greater mortality. Key factors need to be addressed to reduce HAIs.

    INTRODUCTION: Diuretic therapy has been the mainstay of treatment in chronic kidney disease (CKD) patients, primarily for hypertension and fluid overload. Apart from their beneficial effects, diuretic use is associated with adverse renal outcomes. The current study is aimed to determine the outcomes of diuretic therapy.
    METHODOLOGY: A prospective observational study was conducted by inviting pre-dialysis CKD patients. Fluid overload was assessed by Bioimpedance analysis (BIA).
    RESULTS: A total 312 patients (mean age 64.5 ± 6.43) were enrolled. Among 144 (46.1%) diuretic users, furosemide and hydrochlorothiazide (HCTZ) were prescribed in 69 (48%) and 39 (27%) patients, respectively, while 36 (25%) were prescribed with combination therapy (furosemide plus HCTZ). Changes in BP, fluid compartments, eGFR decline and progression to RRT were assessed over a follow-up period of 1 year. Maximum BP control was observed with combination therapy (-19.3 mmHg, p

    OBJECTIVES: The objective of the current study is to analyze different approaches of pharmacists and general practitioners towards availability and use of osteoporosis prescreening tools and to find out reasons that explain non utilization of such tools in clinical practice.
    SETTINGS: Among General practitioners and Community pharmacists in Pulau Penang, Malaysia.
    METHODOLOGY: An explorative cross sectional study was carried out using convenience sampling approach. A pre-validated self- administered questionnaire was used to carry out the study. A total of 170 healthcare professionals participated in study.
    MAIN OUTCOME: Evaluation of awareness, use and opinions of healthcare professionals regarding osteoporosis prescreening tools.
    RESULTS: Response rate of study was 56%. The mean age of the participants was 39.00 + 7.89 years. Less than one third of participants were familiar with term prescreening tools or Clinical decision rules. The only osteoporosis prescreening tool that was recognized and used by majority of participants was FRAX. Participants agreed that low level of awareness regarding availability of prescreening tools poses hindrance in utilization of such tools in clinical practice. Majority of participants showed willingness to gain information and use such tools in future.
    CONCLUSIONS: The results of our study demonstrate an urgent need of implementation of osteoporosis prescreening tools educational and awareness programs among healthcare professionals.

    A bezoar is a concretion of foreign or indigestible matter in the alimentary canal and is usual cause of gastric obstruction. Bezoars can become fragmented and migrate downward leading to intestinal obstruction. Diagnosis of phytobezoar has become challenging in clinical practice due to lack of patient history and inability of patient to correlate preceding events with the episode of bowel obstruction. Bezoar associated small bowel obstruction rarely occurs and is usually found in patients with history of gastrointestinal surgery. Very few cases are reported of small bowel obstruction due to bezoar in healthy population without prior illness or surgery. We present a case of small bowel obstruction due to mushroom bezoar in a 62-year patient with no past history of medical illness or gastric surgery. Enterotomy was performed and a whole piece of undigested mushroom measuring 5 x 3 cm was successfully removed.

    Hot flushes during menopause are distressing for women and result in poor quality of life. Purpose of the current review was to evaluate the available treatment modalities that should be utilised for the management of hot flushes. Menopause refers to last menses of women life and can be declared after amenorrhea of 12 months. Vasomotor symptoms including hot flushes and night sweats are common after menopause, affecting almost 50 - 85% women older than 45 years. The mean increment in core body and skin temperature is 0.5°C and 0.25 - 3°C during a hot flush attack. Low level of estrogen during menopause and its association in triggering episodes of hot flushes, is still under debate. The most accepted hypothesis is a narrowing of the thermoneutral zone (TNZ) triggered by estrogen fluctuations. Although, hormone replacement therapy (HRT) remains the standard treatment for the alleviation of such symptoms, incidence of life threatening side effects restrained medical professionals from its use. Complications associated with the use of HRT can be avoided by appropriate evaluation of patients before initiating therapy. Several guidelines have also recommended HRT (estrogen and progesterone) to be safe for up to a period of seven years. Both hormonal and non-hormonal treatments are used for the management of hot flushes. Since hot flushes are the least appreciated and neglected complication of menopause, current review provides detailed information on its background, pathophysiology and management, and emphasises the need of its treatment.

    Since the emergence of COVID-19, several different medicines including antimicrobials have been administered to patients to treat COVID-19. This is despite limited evidence of the effectiveness of many of these, fueled by misinformation. These utilization patterns have resulted in concerns for patients' safety and a rise in antimicrobial resistance (AMR). Healthcare workers (HCWs) were required to serve in high-risk areas throughout the pandemic. Consequently, they may be inclined towards self-medication. However, they have a responsibility to ensure any medicines recommended or prescribed for the management of patients with COVID-19 are evidence-based. However, this is not always the case. A descriptive cross-sectional study was conducted among HCWs in six districts of the Punjab to assess their knowledge, attitude and practices of self-medication during the ongoing pandemic. This included HCWs working a range of public sector hospitals in the Punjab Province. A total of 1173 HCWs were included in the final analysis. The majority of HCWs possessed good knowledge regarding self-medication and good attitudes. However, 60% were practicing self-medication amid the COVID-19 pandemic. The most frequent medicines consumed by the HCWs under self-medication were antipyretics (100%), antibiotics (80.4%) and vitamins (59.9%). Azithromycin was the most commonly purchase antibiotic (35.1%). In conclusion, HCWs possess good knowledge of, and attitude regarding, medicines they purchased. However, there are concerns that high rates of purchasing antibiotics, especially "Watch" antibiotics, for self-medication may enhance AMR. This needs addressing.

    The World Health Organization (WHO) declared the monkeypox outbreak a public health emergency in June 2022. In Pakistan, positive cases of monkeypox were reported in April 2023. Healthcare workers (HCWs) are considered as a front-line force to combat such outbreaks. A questionnaire-based cross-sectional study was conducted among 11 public sector educational institutions in Punjab, Pakistan, during May and June 2023 among final year medical, pharmacy, and nursing students concerning their knowledge of monkeypox. This included the signs/symptoms of monkeypox. Healthcare students were chosen as they are the HCWs of tomorrow. A total of 389 healthcare students participated in the study, with a mean age of 23.17 ± 1.72 years, and the majority were female. The mean knowledge score was 17.69 ± 4.55 (95% CI 17.24-18.14) out of a maximum total knowledge score of 26 (each correct answer was given a score of 1). The proportion of students with good, moderate, and poor knowledge was 21.6%, 43.2%, and 35.2%, respectively. Age (p = 0.017), gender (p < 0.001), and education (p < 0.001) had a significant impact on the knowledge score. In the multivariate linear regression model, education was the only significant factor linked to knowledge scores. Overall, the majority of future HCWs had moderate knowledge of monkeypox. Consequently, educational activities are needed to improve monkeypox-related knowledge among future HCWs. Furthermore, emerging infectious diseases should be routinely incorporated into HCW curricula.
