RESUMO
BACKGROUND: Successful endodontic treatment needs accurate determination of working length (WL). Electronic apex locators (EALs) were presented as an alternative to radiographic methods; and since then, they have evolved and gained popularity in the determination of WL. However, there is insufficient evidence on the post-operative pain, adequacy, and accuracy of EALs in determining WL. OBJECTIVE: The systematic review and meta-analysis aims to gather evidence regarding the effectiveness of EALs for WL determination when compared to different imaging techniques along with postoperative pain associated with WL determination, the number of radiographs taken during the procedure, the time taken, and the adverse effects. METHODS: For the review, clinical studies with cross-over and parallel-arm randomized controlled trials (RCTs) were searched in seven electronic databases, followed by cross-referencing of the selected studies and related research synthesis. Risk of bias (RoB) assessment was carried out with Cochrane's RoB tool and a random-effects model was used. The meta-analysis was performed with the RevMan software 5.4.1. RESULTS: Eleven eligible RCTs were incorporated into the review and eight RCTs into the meta-analysis, of which five had high RoB and the remaining six had unclear RoB. Following meta-analysis, no significant difference in postoperative pain was found among the EAL and radiograph groups (SMD 0.00, CI .29 to .28, 354 participants; P value = 0.98). Radiograph group showed better WL accuracy (SMD 0.55, CI .11 to .99, 254 participants; P value = 0.02), while the EAL group had 10% better WL adequacy (RR 1.10, CI 1.03-1.18, 573 participants; P value = 0.006). CONCLUSION: We found very low-certainty evidence to support the efficacy of different types of EAL compared to radiography for the outcomes tested. We were unable to reach any conclusions about the superiority of any type of EAL. Well-planned RCTs need to be conducted by standardizing the outcomes and outcome measurement methods.

AIM: Accurate working length determination during root canal treatment is essential for achieving successful outcomes. This study aimed to evaluate the impact of embedding medium on the accuracy of iPex electronic apex locator (EAL). MATERIALS AND METHODS: Sixty-one extracted single-rooted teeth were decoronated and coronally flared with Gates-Glidden burs. Actual canal length (ACL) was obtained by introducing a size 8 K-file until its tip reached the most coronal border of the apical foramen. This step was performed thrice and then averaged. Deducting 0.5 mm from the ACL provided the working length (WL). The teeth were randomly placed in plastic containers filled with freshly mixed alginate, gelatin, or saline, with the lip clip placed in the medium. The blinded operator obtained electronic measurements using iPex by advancing a K-file with a size compatible with the canal attached to the file clip and advanced until the 0.0 mark, then withdrawn to the 0.5 mark. This step was performed thrice and then averaged. Data were analyzed using ANOVA and Tukey's post hoc test, with significance level set at 5% (α = 0.05). RESULTS: The mean difference between WL and iPex length obtained in the gelatin model was significantly longer than the difference with mean iPex length in alginate (p = 0.005) and in saline (p < 0.001). There was no significant difference between iPex readings obtained in alginate and saline (p = 0.249). CONCLUSION: The use of freshly mixed alginate or saline for ex vivo assessment of iPex is recommended, whereas the use of gelatin could increase the chances of readings longer than looked for. CLINICAL SIGNIFICANCE: Identifying the optimum embedding medium for ex vivo testing of EALs permits the comparison and assessment of several factors affecting EALs' precision under standardized conditions. This helps in understanding EAL performance in vivo and in optimizing its clinical utilization.

Background: The increasing emergencies and humanitarian challenges have worsened the mental health condition of women in the Eastern Mediterranean Region. Aim: To assess the prevalence, determinants and interventions to address mental health among women in fragile and humanitarian settings in the Eastern Mediterranean Region. Methods: Using the Preferred Reporting Items for Systematic Review and Meta-analysis guidelines, we reviewed 59 peer-reviewed published studies (PubMed, IMEMR) and grey literature (WHO/IRIS) from January 2001 to February 2023, focusing on women's mental health in the Eastern Mediterranean Region. We then conducted a descriptive analysis of the sociodemographic characteristics. Results: Among the 59 studies reviewed, only 13 of the 48 peer-reviewed studies focused primarily on women's mental health, 11 grey literature records mostly presented grouped regional data, 11 of the 25 studies on mental health among migrants were about those taking refuge in high-income countries. The average prevalence of mental disorders from 32 cross-sectional studies on women aged 12-75 years was 49%, average prevalence of anxiety was 68%, post-traumatic stress disorder was 52%, and depression was 43%. Women exhibited higher level depression than men. Age, educational disparities, and limited access to services were important risk factors for mental health disorder. Several promising interventions emerged. Conclusion: More efforts should be made to provide customized, context-specific solutions to the mental health challenges of women in humanitarian and fragile settings in the Eastern Mediterranean Region, including allocation of more resources to mental health programmes, addressing barriers, enhancing mental health surveillance, and reduction of stigma.

BACKGROUND: Rotavirus (RV) induced diarrhea led to hospitalization and mortality prior to the introduction of the rotavirus vaccine (RVV). The estimated RVV coverage was 86% in children less than one year of age in Pakistan. OBJECTIVES: To determine the difference in the number of diarrheal episodes among children who received and who did not receive RVV, along with the parental and physician's perspectives on the barriers toward RV immunization in children aged less than 1 year in Karachi, Pakistan. METHODS: A mixed-methods study design was conducted in three Primary Healthcare (PHC) private clinics located in different districts of Karachi, Pakistan. Data for RVV status and diarrheal episodes were collected, from medical records in June 2020 for children born between October 2019 to March 2020. Three In-depth Interviews (IDIs) with physicians and three focus group discussions (FGDs) with mothers were conducted for information on awareness and approach towards diarrhea, knowledge, and acceptance of RVV, and barriers towards RV immunization. RESULTS: A total of 430 infants visited the three PHC centres coded as A (n = 144), B (n = 146), and C (n = 140). The mean age of infants was 2.6 ± 0.2 months, 49.5 % were males and 87 (20.2 %) were partial/not vaccinated for RV. Reported diarrheal episodes were 104 (24.2 %), and of these 76 (73.1 %) were partially or not vaccinated, and 83 (79.8 %) were stunted. Recorded diarrhea was significantly associated with partial/not vaccinated status (p < 0.001), stunting (p < 0.001), and by PHC centre location (p < 0.001). PHC-C had the lowest percentage of reported diarrhea, stunting, and non/partially vaccinated status. Qualitative study (FGDs) showed that mothers had lack of awareness and knowledge on the prevention of diarrhea by RVV. Physicians' IDIs pointed towards a lack of sufficient training on RVV. CONCLUSION: Diarrheal episodes in infants were associated with partial or unvaccinated for RVV, low nutritional status, and areas of residence. Low levels of knowledge and awareness in caretakers and lack of training for RVV in PHC physicians were perceived as barriers in controlling diarrheal diseases.

BACKGROUND: There is a dearth of specialized mental health workforce in low- and middle-income countries. Use of mobile technology by frontline community health workers (CHWs) is gaining momentum in Pakistan and needs to be explored as an alternate strategy to improve mental well-being. OBJECTIVE: The aim of this study is to assess the feasibility, acceptability, and usefulness of an app-based counseling intervention delivered by government lady health workers (LHWs) to reduce anxiety and depression in rural Pakistan. METHODS: Project mPareshan is a single-arm, pre- and posttest implementation research trial in Badin District, Sindh, using mixed methods of data collection executed in 3 phases (preintervention, intervention, and postintervention). In the preintervention phase, formative qualitative assessments through focus group discussions and in-depth interviews assess the acceptability and appropriateness of intervention through perceptions of all concerned stakeholders using a specific interview guide. A REDCap (Research Electronic Data Capture)-based baseline survey using Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 Scale (GAD-7) determines the point prevalence of depression and anxiety among consenting men and women older than 18 years. Individuals with mild and moderate anxiety and depression are identified as screen positives (SPs) and are eligible for mPareshan app-based intervention. Mental health literacy of health workers is improved through customized training adapting the World Health Organization's Mental Health Gap Action Programme guide 2.0. The intervention (mPareshan app) consists of tracking, counseling, and referral segments. The tracking segment facilitates participant consent and enrollment while the referral segment is used by LHWs to transfer severe cases to the next level of specialist care. Through the counseling segment, identified SPs are engaged during LHWs' routine home visits in 6 face-to-face 20-minute counseling sessions over 6 months. Each session imparts psychoeducation through audiovisual aids, breathing exercises, and coping skills to reduce stress. Clinical and implementation outcomes include change in mean anxiety and depression scores and identification of facilitators and barriers in intervention uptake and rollout. RESULTS: At the time of this submission (April 2024), we are analyzing the results of 366 individuals who participated in the baseline prevalence survey, the change in knowledge and skills of 72 health workers who took the mPareshan training, change in anxiety and depression scores of 98 SPs recruited for app-based counseling intervention, and perceptions of stakeholders pre- and postintervention gathered through 8 focus group discussions and 18 in-depth interviews. CONCLUSIONS: This trial will assess the feasibility of early home-based mental health screening, counseling, and prompt referrals by frontline health workers to reduce anxiety and depression in the community. The study findings will set the stage for integrating mental health into primary health care.

We report a rare case of paraneoplastic neurological syndrome with dual seropositivity of anti-aquaporin-4 and myelin oligodendrocyte glycoprotein antibodies in a 40 year-old woman with metastatic triple-negative breast cancer. She received multiple lines of anti-neoplastic treatment, including immunotherapy with pembrolizumab, as well as cytotoxic chemotherapy. Paraneoplastic meningoencephalomyelitis developed 2 years after diagnosis of breast cancer and 1 year after discontinuation of immunotherapy with pembrolizumab. She first developed longitudinally extending transverse myelitis followed by left optic neuritis and meningoencephalitis with new enhancing lesions in the brain and spinal leptomeninges. Cerebrospinal fluid analysis during both episodes showed normal glucose and protein, and elevated white blood cell count. Cytology was negative for malignancy. Cerebrospinal fluid was positive for neuromyelitis optica immunoglobulin G antibody anti-aquaporin-4, and autoimmune myelopathy panel was positive for myelin oligodendrocyte glycoprotein antibody. The patient had significant clinical and radiographic improvement after completion of five cycles of plasmapheresis followed by intravenous immunoglobulin. She did not have recurrence of paraneoplastic syndrome with maintenance rituximab every 6 months and daily low-dose prednisone. She succumbed to progressive systemic metastatic disease 4.5 years after her breast cancer diagnosis. This case shows that these antibodies can occur concurrently and cause clinical features, such as both neuromyelitis optica spectrum disorder and myelin oligodendrocyte glycoprotein antibody disease, in a patient with a singular type of cancer. We highlight the importance of testing for paraneoplastic etiology in cancer patients with radiographic menigoencephalomyelitis or meningitis with atypical symptoms of meningeal carcinomatosis and/or cerebrospinal fluid profile negative for leptomeningeal carcinomatosis.
RESUMO
Background: As people live longer, there is an increasing need for hard tissue regeneration and whole-tooth regeneration. Despite the advancements in the field of medicine, the field of regenerative dentistry is still challenging due to the complexity of dental hard tissues. Cross-disciplinary collaboration among material scientists, cellular biologists, and odontologists aimed at developing strategies and uncovering solutions related to dental tissue regeneration. Methodology. A search of the literature was done for pertinent research. Consistent with the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) 2020 Statement, the electronic databases looked at were PubMed, Science Direct, Scopus, and Google Scholar, with the keyword search "hard dental tissue regeneration." Results: Database analysis yielded a total of 476 articles. 222 duplicate articles have been removed in total. Articles that have no connection to the directed regeneration of hard dental tissue were disregarded. The review concluded with the inclusion of four studies that were relevant to our research objective. Conclusion: Current molecular signaling network investigations and novel viewpoints on cellular heterogeneity have made advancements in understanding of the kinetics of dental hard tissue regeneration possible. Here, we outline the fundamentals of stem hard dental tissue maintenance, regeneration, and repair, as well as recent advancements in the field of hard tissue regeneration. These intriguing findings help establish a framework that will eventually enable basic research findings to be utilized towards oral health-improving medicines.
RESUMO
Background/Aim: Probiotics are live microbial supplements that improve the microbial balance in the host animal when administered in adequate amounts. They play an important role in relieving symptoms of many diseases associated with gastrointestinal tract, for example, in necrotizing enterocolitis (NEC), antibiotic-associated diarrhea, relapsing Clostridium difficile colitis, Helicobacter pylori infections, and inflammatory bowel disease (IBD). In this narrative review, the authors aim to evaluate the role of different probiotic formulations in treating gastrointestinal diseases in pediatric population aged 18 years or younger and highlight the main considerations for selecting probiotic formulations for use in this population. Methodology: The authors searched PubMed and Clinicaltrials.gov from inception to 24th July 2022, without any restrictions. Using an iterative process, the authors subsequently added papers through hand-searching citations contained within retrieved articles and relevant systematic reviews and meta-analyses. Results: The effectiveness of single-organism and composite probiotics in treating gastrointestinal disorders in pediatric patients aged 18 or under were analyzed and compared in this study. A total of 39 studies were reviewed and categorized based on positive and negative outcomes, and compared with a placebo, resulting in 25 studies for single-organism and 14 studies for composite probiotics. Gastrointestinal disorders studied included NEC, acute gastroenteritis (AGE), Acute Diarrhea, Ulcerative Colitis (UC), and others. The results show that probiotics are effective in treating various gastrointestinal disorders in children under 18, with single-organism probiotics demonstrating significant positive outcomes in most studies, and composite probiotics showing positive outcomes in all studies analyzed, with a low incidence of negative outcomes for both types. Conclusion: This study concludes that single-organism and composite probiotics are effective complementary therapies for treating gastrointestinal disorders in the pediatric population. Hence, healthcare professionals should consider using probiotics in standard treatment regimens, and educating guardians can enhance the benefits of probiotic therapy. Further research is recommended to identify the optimal strains and dosages for specific conditions and demographics. The integration of probiotics in clinical practice and ongoing research can contribute to reducing the incidence and severity of gastrointestinal disorders in pediatric patients.
RESUMO
Introduction Acute Coronary Syndrome (ACS) is a critical condition characterized by reduced blood flow to the heart and includes various conditions such as ST-elevation myocardial infarction, non-ST elevation myocardial infarction, and unstable angina. Objectives The aim of this study was to investigate age-related patterns of symptoms and risk factors in ACS patients and to evaluate how diagnostic test results differ among various age groups of ACS patients. Methodology This retrospective study was conducted from May to November of 2023 on patients with acute coronary syndrome admitted to the cardiology ward of Rehman Medical Institute (RMI), Peshawar. The sample size was 137 ACS-diagnosed patients based on the inclusion and exclusion criteria. After getting ethical approval from the institutional ethical approval board, data were collected for the entire year of 2022 based on proforma with the variables demographic data, troponin I level, presented symptoms, and associated co-morbidities of the patients. The inclusion criteria were patients of all genders, patients diagnosed with Acute Coronary Syndrome (ACS), and patients whose records were available in the cardiology department of Rehman Medical Institute. Results The results show that ACS is more prevalent in the age group of 50-69 years (p=0.037) and is significantly more common in males (p=0.019). Chest pain emerged as the predominant symptom, with a significant association of p=0.029 between chest pain and patients of ACS in the age group 30-49 years. While raised troponin I levels were prevalent across all age groups. Moreover, specific risk factors such as diabetes mellitus, hypertension, and family history of CAD showed the significance of p= 0.04, p=0.006, and p=0.021, respectively, with the age group 50-69 years old. Conclusion This study highlights the importance of considering age and gender in ACS management and provides insights into age-related patterns of symptoms and risk factors, which can contribute to optimizing preventive strategies and improving patient care. Further research is needed to explore the underlying mechanisms and assess long-term outcomes in different age groups.
RESUMO
Homelessness poses complex health obstacles for individuals and communities. Peer and lay health worker programs aim to increase access to health care and improve health outcomes for PEH by building trust and empowering community-based workers. The scope and breadth of peer and lay health worker programs among PEH has not been synthesized. The primary objective of this scoping review is to understand the context (setting, community, condition or disease) encompassing peer and lay health worker programs within the homelessness sector. The secondary objective is to examine the factors that either facilitate or hinder the effectiveness of peer and lay health worker programs when applied to people experiencing homelessness (PEH). We searched CINHAL, Cochrane, Web of Science Core Collection, PsycINFO, Google Scholar and MEDLINE. We conducted independent and duplicate screening of titles and abstracts, and extracted information from eligible studies including study and intervention characteristics, peer personnel characteristics, outcome measures, and the inhibitors and enablers of effective programs. We discuss how peer and lay health work programs have successfully been implemented in various contexts including substance use, chronic disease management, harm reduction, and mental health among people experiencing homelessness. These programs reported four themes of enablers (shared experiences, trust and rapport, strong knowledge base, and flexibility of role) and five themes of barriers and inhibitors (lack of support and clear scope of role, poor attendance, precarious work and high turnover, safety, and mental well-being and relational boundaries). Organizations seeking to implement these interventions should anticipate and plan around the enablers and barriers to promote program success. Further investigation is needed to understand how peer and lay health work programs are implemented, the mechanisms and processes that drive effective peer and lay health work among PEH, and to establish best practices for these programs.
RESUMO
Background: The National Health Vision of Pakistan 2016-2025 is to provide affordable health services through a resilient and responsive health system for achieving health-related Sustainable Development Goals (SDGs) and universal health coverage (UHC) targets. Through this study, we wanted to identify the research priorities at the national level that would help to provide the necessary evidence for achieving this vision through essential package of health services (EPHS). Methods: We followed World Health Organization (WHO) guidance for undertaking research priority-setting exercises and the Child Health and Nutrition Research Initiative (CHNRI) methodology in conducting this national exercise. The proposed research options for the next three to five years were identified in five thematic research areas: communicable diseases; non-communicable diseases (NCDs) and injuries; reproductive, maternal, newborn, child, and adolescent health (RMNCAH); mental health; and health systems and services. We assessed these research options against five priority-setting criteria: feasibility, public health importance, sustainability, equity, and community involvement. Results: Forty-three experts proposed 272 research ideas, which were consolidated into a list of 155 research options and sent back to the experts for scoring. The top 10 research priorities in each of the five research areas were identified based on the weighted research priority scores (wRPS) rankings. Tuberculosis and antimicrobial resistance; NCD screening and prevention; maternal and neonatal mortality; mental health of children, adolescents, and youth; and human resource management were the issues that were most frequently reflected in the list of research priorities. Most research priorities aimed to identify barriers to the implementation of interventions. Conclusions: Through this exercise, we identified the top 50 national health research priorities, which also have a strong correlation with EPHS interventions. To realise the findings of this exercise, funding agencies should establish funding mechanisms to support the undertaking of the identified research priorities, and academic researchers should actually utilise them in future studies. Such activities could hopefully contribute to achieving the national health goals.

Acute leukemia (AL) is a critical neoplasm of white blood cells with two main subtypes: acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML). This study is focused on understanding the association of the preleukemic disease aplastic anemia (APA) with ALL and AML at metallomic level, using healthy subjects as a control. In this study, a validated and efficient inductively coupled plasma-mass spectrometry/MS-based workflow was employed to profile a total of 13 metallomic features. The study encompassed 41 patients with AML, 62 patients with ALL, 46 patients with APA, and 55 age-matched healthy controls. The metallomic features consisted of eight essential elements (Ca, Co, Cu, Fe, Mg, Mn, Se, and Zn) and five non-essential/toxic elements (Ag, Cd, Cr, Ni, and Pb). Six out of the 13 elements were found to be substantially different (P < .05) using absolute concentrations between serum samples of AL (ALL and AML) and preleukemia (APA) patients in comparison with healthy subjects. Elements including magnesium, calcium, iron, copper, and zinc were upregulated and only one element (chromium) was downregulated in serum samples of disease when compared with healthy subjects. Through the utilization of both univariate tests and multivariate classification modeling, it was determined that chromium exhibited a progressive behavior among the studied elements. Specifically, chromium displayed a sequential upregulation from healthy individuals to preleukemic disease (APA), and ultimately in patients diagnosed with ALL. Overall, metallomic-based biomarkers may have the utility to predict the association of APA with ALL.
RESUMO
BACKGROUND: Reduction of diastolic blood pressure (DBP) below 70 mmHg may decrease perfusion to the heart and worsen cardiovascular (CV) outcomes. AIMS: Explore the association between low DBP and CV outcomes. METHODS: We searched the online databases until August 2023 for studies reporting the risk of all-cause mortality (ACM) or CV outcomes in patients with low versus normal DBP (70-80mm Hg). RESULTS: Inclusion of 10 studies (n = 1,998,223 patients) found that a mean achieved DBP < 60 mmHg was associated with an increased risk of all-cause mortality (HR 1.48; 95 % CI [1.26-1.74]), especially in patients with pre-existing CV disease. It was also associated to a higher risk of major adverse cardiovascular events (HR 1.84; [1.28-2.65]) and myocardial infarction (HR 1.49; [1.13-1.97]). A DBP of 60-69 mmHg was associated with an increased risk of all-cause mortality (HR 1.11; [1.03-1.20]). CONCLUSION: Reduction of DBP, particularly below 60 mmHg, is associated with increased risk of ACM.

Breast milk is a vital source of nutrition for breastfed infants, providing essential nutrients and elements but, in some cases, toxic ones. This is the first case-control study that investigated the elemental profile of breast milk samples collected from mothers residing in Matiari (Sindh), a region with insufficient industrial waste management, and its potential impact on infants' anthropometrics. Precisely, 62 milk samples, including 42 cases and 20 controls, were analyzed using the ICP-MS technique. Overall, six elements showed significance between the two groups, arsenic (As) was present at 0.68 µg/L in cases and absent in controls, while lead (Pb) exhibited elevated concentrations in the case group at 4.56 µg/L compared to 0.25 µg/L in controls, well-known for their toxicity. Barium (Ba) and manganese (Mn) levels were also higher in cases, associated with reported health effects on child well-being. Essential elements molybdenum (Mo) and selenium (Se) were higher in the controls. Furthermore, the association of these metals with the child growth standards as per WHO guidelines was calculated. Linear regression analysis revealed As negatively associated with WAZ and WHZ scores, while Mo was positively associated with WAZ, WHZ, and HAZ scores. These findings highlight serious health concerns in the region, where toxic elements pervade drinking water and food sources. Immediate actions are imperative to maintain the wellness of future generations.

Polyphenolic compounds are vital components of plants. However, their analysis is particularly difficult and challenging due to their similar chemical and structural properties. In this study, we developed a simple and reproducible HPLC-DAD protocol for determining nineteen pharmacologically important polyphenols in plant-based food samples, including fruits (apple, banana, grapefruit, peach, grapes, plum, and pear), vegetables (onion, cabbage, capsicum, garlic, lemon, tomato, potato, and spinach), and other edible items (corn, kidney beans, green tea, black tea, and turmeric). The reference standards were pooled into four different groups based on logP values and expected retention time to avoid compound co-elution. These developed methods will be useful for the qualitative and quantitative analysis of biologically important polyphenolic compounds in various food samples and botanicals.
RESUMO
Incentive-linked prescribing (ILP) is considered a controversial practice universally. If incentivised, physicians may prioritise meeting pharmaceutical sales targets through prescriptions, rather than considering patients' health and wellbeing. Despite the potential harms of ILP to patients and important stakeholders in the healthcare system, healthcare consumers (HCCs) which include patients and the general public often have far less awareness about the practice of pharmaceutical incentivisation of physicians. We conducted a scoping review to explore what existing research says about HCCs' perceptions of the financial relationship between physicians and pharmaceutical companies. To conduct this scoping review, we followed Arksey and O'Malley's five-stage framework: identifying research questions, identifying relevant studies, selecting eligible studies, data charting, and collating, summarising, and reporting results. We also used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses' extension for scoping reviews (PRISMA-ScR), as a guide to organise the information in this review. Quantitative and qualitative studies with patients and the general public, published in the English language were identified through searches of Scopus, Medline (OVID), EMBASE (OVID), and Google Scholar. Three themes emerged through the analysis of the 13 eligible studies: understanding of incentivisation, perceptions of hazards linked to ILP, and HCCs' suggestions to address it. We found documentation that HCCs exhibited a range of knowledge from good to insufficient about the pharmaceutical incentivisation of physicians. HCCs perceived several hazards linked to ILP such as a lack of trust in physicians and the healthcare system, the prescribing of unnecessary medications, and the negative effect on physicians' reputations in society. In addition to strong regulatory controls, it is critical that physicians self-regulate their behaviour, and publicly disclose if they have any financial ties with pharmaceutical companies. Doing so can contribute to trust between patients and physicians, an important part of patient-focused care and a contributor to user confidence in the wider health system.
RESUMO
OBJECTIVES: Pharmaceutical incentivisation of physicians for profit maximisation is a well-documented health system challenge. This study examined general practitioners' (GPs) reactions to pharmaceutical incentivisation offers in one region in Pakistan. METHODS: We used the Standardised Pharmaceutical Sales Representative (SPSR) method and qualitative interviews with GPs. SPSRs were field researchers representing mock pharmaceutical companies who recorded their observations of 267 GPs' responses to pharmaceutical incentivisation offers. We triangulated SPSR data using qualitative interviews with a subset of the same GPs to gather information about how they interpreted different interaction outcomes. RESULTS: We found four major outcomes for GPs being offered incentives by pharmaceutical companies for prescribing medications. GPs might agree to make incentivisation deals, reject incentivisation offers, disallow PSRs to access them, or remain indeterminate with no clear indication of acceptance or rejection of incentivisation offers. GPs rejecting SPSRs' incentivisation offers indicated having active commitments to other pharmaceutical companies, not being able to work with unheard-of companies, and asking SPSRs to return later. CONCLUSIONS: The GP-pharmaceutical sales representative interaction that centres on profit-maximisation is complex as offers to engage in prescribing for mutual financial benefit are not taken up immediately. The SPSR method helps understand the extent of distortion of practices impacted by incentivisation. Such an understanding can support the development of strategies to control unethical behaviours.

Procedural sedation and analgesia (PSA) are a common practice in emergency departments (EDs), aiming to alleviate pain, anxiety, and discomfort during various medical procedures. We have undertaken a systematic review and meta-analysis with the aim of assessing the incidence of adverse events associated with PSA, including those related to individual drugs and various drug combinations. The study adhered to PRISMA guidelines for a systematic review and meta-analysis of adverse events in ED sedation. A comprehensive search strategy was employed across ten databases, supplemented by searches on clinicaltrials.gov and manual reviews of reference lists. Data extraction focused on medication administration and adverse events. The study considered four types of adverse events: cardiac, respiratory, gastrointestinal, and neurological. Only randomized controlled trials (RCTs) focusing on PSA administered to adult patients within the ED setting were included. The statistical analysis employed OpenMeta Analyst to conduct a one-arm meta-analysis, with findings presented alongside their corresponding 95% Confidence Intervals. Forest plots were constructed to combine and evaluate results, and sensitivity analyses were performed to identify sources of heterogeneity. From a literature search of 4246 records, 32 RCTs were deemed suitable for this meta-analysis. The analysis included 6377 procedural sedations. The most common adverse event was hypoxia, with an incidence rate of 78.5 per 1000 sedations (95% CI = 77.5-133.5). This was followed by apnea and hypotension, with incidence rates of 31 (95% CI = 19.5-41.8) and 28.1 (95% CI = 17.4-38.9) per 1,000 sedations, respectively. Agitation and vomiting each occurred in 15.6 per 1,000 sedations (95% CI = 8.7-22.6). Severe adverse events were rare, with bradycardia observed in 16.7 per 1,000 sedations, laryngospasm in 2.9 per 1,000 sedations (95% CI = - 0.1 to 6), intubation in 10.8 per 1,000 sedations (95% CI = 4-17), and aspiration in 2.7 per 1,000 sedations (95% CI = - 0.3 to 5.7). Ketamine is found to be the safest option in terms of respiratory adverse events, with the lowest rates of apnea and hypoxia, making it the least respiratory depressant among the evaluated drugs. Etomidate has the least occurrence of hypotension when used alone. Propofol has the highest incidence of hypotension when used alone and ranks second in hypoxia-related adverse events after midazolam. Using combinations of sedating agents, such as propofol and ketamine, has been found to offer several advantages over single drugs, especially in reducing adverse events like vomiting, intubation difficulty, hypotension, bradycardia, and laryngospasm. The combination significantly reduces the incidence of hypotension compared to using propofol or ketamine individually. Despite the regular use of procedural sedation, it can sometimes lead to serious adverse events. Respiratory issues like apnea and hypoxia, while not common, do occur more often than cardiovascular problems such as hypotension. However, the least frequent respiratory complications, which can also pose a threat to life, include laryngospasm, aspiration, and intubation. These incidents are extremely rare.
RESUMO
BACKGROUND: Despite known adverse impacts on patients and health systems, "incentive-linked prescribing," which describes the prescribing of medicines that result in personal benefits for the prescriber, remains a widespread and hidden impediment to quality of healthcare. We investigated factors perpetuating incentive-linked prescribing among primary care physicians in for-profit practices (referred to as private doctors - PDs), using Pakistan as a case study. METHODS: Our mixed-methods study synthesised insights from a survey of 419 systematically sampled PDs and 68 semi-structured interviews with PDs (n=28), pharmaceutical sales representatives (SRs) (n=12), and provincial and national policy actors (n=28). For the survey, we built a verified database of all registered PDs within Karachi, Pakistan's most populous city, administered an electronic questionnaire in-person and descriptively analysed the data. Semi-structured interviews incorporated a vignette-based exercise and data was analysed using an interpretive approach. RESULTS: Our survey showed that 90% of PDs met pharmaceutical SRs weekly. Three interlinked factors perpetuating incentive-linked prescribing we identified were: gaps in understanding of conflicts of interest and loss of values among doctors; financial pressures on doctors operating in a (largely) privately financed health-system, exacerbated by competition with unqualified healthcare providers; and aggressive incentivisation by pharmaceutical companies, linked to low political will to regulate an over-saturated pharmaceutical market. CONCLUSION: Regular interactions between pharmaceutical companies and PDs are normalised in our study setting. Progress on regulating these is hindered by the substantial role of incentive-linked prescribing in the financial success of physicians and pharmaceutical industry employees. A first step towards addressing the entrenchment of incentive-linked prescribing may be to reduce opposition to restrictions on incentivisation of physicians from stakeholders within the pharmaceutical industry, physicians themselves, and policy-makers concerned about curtailing growth of the pharmaceutical industry.

Background and Aim: Afghanistan is grappling with a severe health crisis marked by a high prevalence of infectious diseases, particularly tuberculosis, malaria, HIV, and the added strain of the COVID-19 pandemic. The nation's healthcare system, already fragile, faces formidable challenges. Socioeconomic constraints, including limited resources and financial barriers, hinder healthcare accessibility, leading to delayed or inadequate care. Environmental factors, such as poor sanitation and crowded living conditions, exacerbate the transmission of diseases, especially waterborne illnesses. Governance issues, encompassing transparency, corruption, and political instability, disrupt healthcare efficiency and resource allocation. Addressing these multifaceted issues is vital to enhance Afghanistan's healthcare system and overall well-being. The withdrawal of international support has exacerbated these challenges. The primary research goal is to deeply understand Afghanistan's health system, focusing on the major disease burdens: Tuberculosis, Malaria, AIDS, COVID-19, Measles, Hepatitis, and Cholera. The study aims to assess the feasibility and effectiveness of current approaches, presenting a comprehensive view of challenges and opportunities within the Afghan healthcare system. The research concludes by highlighting policy implications, practical implementation, and offering recommendations for future endeavors. Methodology: This paper provides a thorough analysis of the literature concerning infectious diseases in Afghanistan and the enhancement of the healthcare system in the nation. A systematic exploration of the literature was conducted through PubMed and Google Scholar databases. The search terms used encompassed "Tuberculosis" OR "TB," "Malaria," "acquired immunodeficiency syndrome" OR "AIDS," "Human immunodeficiency virus" OR "HIV," "COVID-19," "Measles," "Hepatitis virus," "Cholera," "Health system improvement," and "Afghanistan." Additionally, external sources like UNICEF, CDC, and WHO were referenced. Results: In conclusion, while improving access to vital medicines and vaccines is crucial for enhancing health outcomes in Afghanistan, significant challenges must be addressed to ensure the effectiveness and sustainability of such strategies. The Afghan health system's fragile governance, corruption, logistical complexities, and failure to address broader social and economic factors pose significant risks and obstacles to the implementation of proposed health strategies. Therefore, the strategies discussed in this analysis align with key Sustainable Development Goals, particularly SDG 3, and their successful implementation will have implications not only for the health and well-being of Afghanistan but also for global health. Conclusion: Hence, by adopting a comprehensive approach with complementary interventions as discussed, we can address issues in the Afghan health system and reduce transmissible diseases' burden, thereby building a better world for all.
