Compliance with smoke-free legislation and smoking behaviour: an observational field study in Karachi, Pakistan.

Objective: To observe compliance with smoke-free law at different public places in an urban setting. METHODS: The cross-sectional study was conducted from January to June 2022 after approval from the ethics review board of Jinnah Sindh Medical University, Karachi, at public places, including public and private offices, health institutions, education institutions, malls, markets and eateries, in 5 districts of Karachi. Boundary, entrance, waiting areas/corridors, toilet areas and eating areas were assessed using a checklist for smoke-free law compliance. Places were considered compliant if no smoking activity, cigarette butt litter or ashtrays was found. Data was analysed using SPSS 21. RESULTS: Out of 400 places observed, there were 80(20%) in each of the 5 districts. Overall, 36(44%) of the venues showed indoor compliance and 10(12%) showed outdoor compliance. Presence of cigarette butts was observed at 350(87.5%) outdoor places around the boundary of the premises. Only 38(9.5%) of the places had no smoking boards outdoors and at the entrance, with 16(4%) being clearly visible. Also, 27(43%) of educational institutions had a cigarette shop within 50 metres of the boundary. Conclusion: The city was found to have poor implementation of smoke-free laws, especially for outdoor areas, exposing the public to constant second-hand smoke.

Exploring the serotonin-probiotics-gut health axis: A review of current evidence and potential mechanisms.

Modulatory effects of serotonin (5-Hydroxytryptamine [5-HT]) have been seen in hepatic, neurological/psychiatric, and gastrointestinal (GI) disorders. Probiotics are live microorganisms that confer health benefits to their host. Recent research has suggested that probiotics can promote serotonin signaling, a crucial pathway in the regulation of mood, cognition, and other physiological processes. Reviewing the literature, we find that peripheral serotonin increases nutrient uptake and storage, regulates the composition of the gut microbiota, and is involved in mediating neuronal disorders. This review explores the mechanisms underlying the probiotic-mediated increase in serotonin signaling, highlighting the role of gut microbiota in the regulation of serotonin production and the modulation of neurotransmitter receptors. Additionally, this review discusses the potential clinical implications of probiotics as a therapeutic strategy for disorders associated with altered serotonin signaling, such as GI and neurological disorders. Overall, this review demonstrates the potential of probiotics as a promising avenue for the treatment of serotonin-related disorders and signaling of serotonin.

Comparison of inflammatory markers in COVID-19 patients- a study based on disease severity groups.

Objectives: To compare different inflammatory markers in various coronavirus disease 2019 severity groups. METHODS: The cross-sectional, retrospective, comparative study was conducted at the Central Park Teaching Hospital, Lahore, Pakistan, and comprised data from April to June 2021 of coronavirus disease 2019 inpatients. The data was divided into mild, moderate and severe/critical category using the World Health Organisation interim guidelines. Data was analysed using SPSS 22. RESULTS: Of the 50 patients, 29(58%) were males and 21(42%) were females. The overall mean age was 54.12±21.23 years. The mean age was 62±17.1years in critical group compared to 50±19.7 years in mild and 52±15.9 years in moderate groups. There were 8(16%) patients in the mild group, 16(32%) in the moderate group and 26(52%) in the critical severity group. Mortality was the outcome in overall 19(38%) cases, and 14(73.7%) of them were in the critical group (p=0.03). C reactive protein, interleukin-6, serum ferritin and D-dimer levels were significantly different among the groups (p<0.05). CONCLUSIONS: Older people were found to have experienced coronavirus disease 2019 in more severe forms. The inflammatory markers were significantly high in patients with severe disease and were associated with high mortality.

Thrombocytopenia and hyperthyroidism: A case report and literature review.

Key Clinical Message: Immune thrombocytopenic purpura (ITP) is very challenging to diagnose with concurrent comorbidities affecting platelet count including PAH and autoimmune thyroid disease. ITP resolution can be achieved with tailored treatment of the underlying conditions to avoid adverse events. Abstract: Immune thrombocytopenic purpura (ITP) is an autoimmune disorder characterized by a platelet count of <100 × 109/L in the absence of other causes of thrombocytopenia. It is classified as primary or idiopathic and secondary due to various coexisting conditions, including autoimmune thyroid diseases. It is especially challenging when the patient has comorbidities that affect platelet count easily, leading to anchoring bias. The first-line treatment of ITP is corticosteroids, and it is also recommended to treat the primary causes of secondary ITP. Here, the authors report a case of secondary ITP in a patient with a recent diagnosis of Grave's disease and a history of idiopathic pulmonary hypertension with baseline chronic thrombocytopenia, possible mechanisms, and treatment strategies with a multidisciplinary approach.

Association of exercise, brain-derived neurotrophic factor, and cognition among older women: A systematic review and meta-analysis.

This systematic review and meta-analysis explored the effects of structured exercise regimens on brain-derived neurotrophic factor (BDNF) levels, a proxy for cognitive function, in older women. In this study, we collated evidence from the available clinical trials that reported BDNF levels and other outcomes following structured exercise regimens. Adhering to PRISMA Statement 2020 guidelines. PubMed/MEDLINE, Scopus, CINAHL Plus, and Cochrane were systematically searched using a combination of the following keywords: brain-derived neurotrophic factor, women, exercise, older, cognition, and/or cognitive. A random-effects model was applied; the statistical analysis was conducted in RevMan 5.4 (Cochrane). The risk of bias in the included trials was assessed using the Risk of Bias in Non-Randomized Studies of Interventions (ROBINS-I) tool. Across 12 trials, 994 older women were included that were enrolled in different exercise regimens globally. Exercise regimens were categorized as aerobic, resistance/power training, aquatic, taekwondo, and multimodal and ranging from 30 to 60 min, 1-5 times per week across 5-24 weeks. Moderate improvement (Cohen's d: 0.44, 95% CI: 0.04-0.84, p = 0.03) was found in BDNF levels across all trials. There was a small yet insignificant improvement in mini-mental state examination (MMSE) scores (Cohen's d: 0.17, 95% CI: -0.79-1.13, p = 0.73). Aerobic exercise, aquatic exercise, and multimodal regimens showed significant association with improved BDNF levels but the sample size for individual exercise regimens was small A main limitation was the inclusion of 114 (10.3%) males in the data, introducing gender bias. This study provides novel insight into the association between various exercise regimens and BDNF levels among older women.

Prescribing practices of Hormone Therapy for Menopausal females by OBGYN of Pakistan.

Objectives: To assess the prescribing practice of obstetricians and gynecologists (OBGYN) regarding Menopausal Hormone therapy (MHT) for menopausal females and assess the knowledge regarding indications for prescribing MHT and identify the barriers to HRT. Methods: This was a cross-sectional study conducted from May 2021 to December 2021. The participants were OBGYN experts (MCPS, FCPS, MRCOG) and senior experts. The tool was formulated after looking at contemporary literature and then validated by experts for face, content and construct validity. It was piloted and hence fourth given to study participants after approval by IRB of JSMU. Data was analyzed by SPSS version 22. Mean and Standard Deviation of categories in Likert scale were calculated. Results: Majority of the participant gynecologists prescribed HRT for Hot flushes and vaginal dryness having the highest mean scores nearing 4 on a Likert scale of (1-5). The prescription for other menopausal symptoms was observed to be less. The highest score for category of women in whom hormone therapy is specifically justified was "Premature ovarian failure" (4.37) followed by "Hysterectomy with bilateral oophorectomy before the age of 50" (4.23). Conclusion: Pakistani gynecologists are more cautious in their management strategies concerning MHT. Most of the gynecologists showed good and up to date information while prescribing MHT however knowledge for preventing fractures, alleviating anxiety/depression and weight gain was less among the gynecologist of Pakistan. We recommend refresher courses and online webinars for updated information on menopause and its management.

Enhancing satisfaction and respect for health care personnel: a mixed-methods case study of a community-based intervention.

Health care personnel (HCP) face violence as a result of lack of satisfaction and respect among community members. It is imperative for HCP to engage in social work by involving communities for enhancing satisfaction and respect for them. This study attempted to provide insight on this phenomenon by using a mixed-methods concurrent embedded approach. Communities were selected based on modified Solomon four-group design from Karachi in southern province and from three cities of northern province, Khyber Pakhtunkhwa of Pakistan. Focus group discussions and in-depth interviews took place for formulating the quantitative tool. Six hundred pretests were done prior to introducing low-cost community-based interventions followed by 601 posttests. We found increased levels of satisfaction in both provinces, whereas level of respect increased significantly in Karachi in the southern province only. Qualitative interviews revealed the important role played by media and religious leaders. These findings suggest that satisfaction and respect for HCP can be enhanced through community support, involvement of religious leaders, and effective media campaigns.

Small Bowel Adenocarcinoma: A Rare Case of Iron Deficiency Anemia.

Neoplasms of the small bowel are relatively rare, with less than 5% occurrence among other GI cases. Primary adenocarcinoma, an aggressive sub-type of small bowel cancers, usually presents with vague blood loss and abdominal pain symptoms, causing a delayed diagnosis at an advanced stage of the disease and a poor prognosis. The preferable treatment of choice is surgical resection with chemotherapy, which has shown to have survival benefits. Here we present a case of a 66-year-old male patient with persistent iron deficiency anemia requiring multiple blood transfusions and an unexplained weight loss. A series of diagnostic tests, including upper and lower GI endoscopy, Tc-99 RBC scintigraphy, barium follow-through, CT scans, bone marrow biopsy, esophagogastroduodenoscopy and colonoscopy were inconclusive. He was later diagnosed with a small bowel adenocarcinoma on exploratory laparotomy and surgically treated. Adjuvant chemotherapy was also started. Our case report highlights the course of SBA presenting in an unusual way which was challenging to diagnose with the standard investigations to help physicians/surgeons suspect it at an early stage in the future. This may save patients and help avoid delayed diagnosis or misdiagnosis, especially in patients with an unusual presentation like our patient who presented only with iron deficiency anemia.

Working Conditions and Work-Related Health Issues of Female Domestic Workers in Four Districts of Karachi.

OBJECTIVES: To determine the working conditions and work-related health issues of female domestic workers (FDWs) in four districts of Karachi. METHODS: Population-based cross-sectional study was conducted in four squatter settlements of Karachi with sample size of 406 FDWs in 2018. Pretested questionnaire was administered to collect data through snowball technique. Multivariate logistic regression examined the association between different factors and experiencing violence, work-related injuries, and chemical exposures. RESULTS: Only (14.5%) of domestic workers earned Rs 15 000 (75 GBP month-1) and above. >1% had financial support for the health or education of children. Verbal violence included shouting (40.9%), constant critique of work (17.2%), and job threats (13.5%). Common workplace injuries were cuts (30.8%), burns (27.6%), and bruises (23.6%). Doing laundry showed significant positive association with experiencing cuts [odds ratio (OR) = 2.09; 1.15-3.71], looking after children to bruises (OR = 2.29; 1.07-4.88), and cooking to burns (OR = 4.66; 2.68-8.08). CONCLUSIONS: Creating economic environment which is equal for all low wage workers, setting up domestic labor standards and holding employers accountable to them is essential.

Emerging pharmacy services; Recommendations for emergency care of COVID-19 pandemic in low and middle-income countries.

The ongoing outbreak of coronavirus diseases (COVID-19) has been declared as Pandemic by the World Health Organization and now become a global health emergency. Low and Middle income-countries lack standard pharmacy services in terms of staff, education, training, pharmaceutical care, research, and practice. The literature aimed to provide emerging pharmacy services and recommend it to be implemented in low and middle-income countries. Currently, pharmacies were easily accessible sites by the community, a trained staff under the guidance of pharmacist can be helpful for the management of visiting customers. In the surge of disease, pharmacists proved themselves as a frontline defense for the community by significant contribution in identifying, reporting, and managing COVID-19 patients through pharmaceutical care services at the community level, hospital/clinical level, and through Tele-pharmaceutical services.

Informed consent practice for obstetric and gynaecologic procedures: A patients' perspective from a developing country.

OBJECTIVES: To assess the surgical informed consent (SIC) practices for obstetric and gynaecological (OB-GYN) procedures at different hospitals in Pakistan. METHODS: Study was conducted in five hospitals (three public and two private) of Peshawar, Pakistan. A pretested structured tablet-based questionnaire was administered from October 2016 through January 2017 among post-op OB-GYN patients. RESULTS: About 27% of the patients (significantly more in private hospitals, P = 0.001) did not remember a formal consent administration. Most patients (80%) felt they had no choice about signing the consent. About 65% (mostly in public as compared with private hospitals) mentioned that they would have signed it regardless of the specifics in it (P < 0.001). Patients had increased odds to recall consent if they felt empowered, odds ratio (OR) = 4.5; had an opportunity to ask questions, OR = 7.2; wanted more explanation, OR = 2.8; and had consent administered in their mother tongue, OR = 6.9. DISCUSSION: Patients' recall of key elements of consent was low. The time spent with the patient for consenting was much shorter than recommended. The printed consent forms were mostly not available in patients' mother tongue. CONCLUSIONS: Consent practice for OB-GYN procedures was suboptimal in studied hospitals. Patients' attitude toward informed consent practices largely reflected providers' focus on obtaining a legally valid signed consent as opposed to administering a consent that empowers patients to make an informed decision in the absence of any external pressure.

Augmentation of oral submucous fibrosis by NSAIDs in the presence of risk factors.

Various Risk factors initiate Submucous fibrosis which may be augmented by NSAIDs. A number of animal studies on their mechanism indirectly support it especially regarding alterations in prostaglandin synthesis. This study has been designed to find association of these drugs with Oral Submucous fibrosis in the presence of risk factors. Newly diagnosed patients of Oral Sub mucous fibrosis were recruited for this study who attended Dental Department of Karachi Medical and Dental College from July 1 till Dec 31, 2013.A structured interview and medical record of each patient was used to determine the demographic profile, any addiction, previous and present illnesses and drug (s) used. Through examination of Oral cavity was carried out to access the severity of disease as per modified Khanna & Andrade Classification (1995). Statistical Analysis was done by SPSS 15. Total 102 patients were recruited from dental OPD as per criteria of inclusion. Among these patients 36 (49.31%) were using NSAIDs in which Acetaminophen (30.55%), Acetylsalicylic acid (25.00%) and Diclophenac (19.44%) were 1st, 2nd and 3rd most common drugs. Data shows that 14 patients (28.88%) had mild and 22(61.11%) had sever fibrosis which was significantly high (P<0.05). Mild fibrosis was seen in 05 (45.46%) and Sever fibrosis in 06 (54.54%) out of total 11 patients who were using NSAIDSs since less than or equal to 6 months. Similarly mild fibrosis was seen in 09 (36.00%) and Sever fibrosis in 16 (64.00%) out of total 25 patients who were on NSAIDs since more than 6 months. No statistical significant difference (P>0.05) in severity of fibrosis is seen in patients who were using NSAIDs since less than or equal to 6 months but statistical significant difference (P<0.05) in severity of fibrosis is seen in patients who on these drugs since more than 6 months. Addiction burden was calculated by Average Duration x Average Frequency, which was 92.72 for Pan, 88.88 for Supari and 61.30 for Miscellaneous. No statistically significant difference (P>0.05) was seen in addiction burden of various substances in these patients. An association of NSAIDs with Oral Sub mucous fibrosis exists. The pathology is augmented if these drugs are used in the presence of risk factors. Therefore these drugs should not be prescribed to these patients until a clear benefit is not targeted.
