RESUMO

Background: A wide variety of electrocardiogram (ECG) changes can manifest with antidepressant drugs, occurring at both therapeutic doses and toxic levels. Notably, ECG abnormalities like wide QRS and QT prolongation may be observed in poisoned patients with tricyclic antidepressants (TCAs), indicating severe conditions that necessitate the implementation of cardiac monitoring systems. This study aimed to investigate ECG Abnormality in poisoned patients with tricyclic antidepressants. Methods: This retrospective patient record study was conducted at Razi Hospital in Ahvaz, Iran, from 2006 to 2009. Patient information was extracted from hospital medical records after the established protocol. The chi-square test was employed for initial analysis; subsequently, logistic regression was applied to identify risk factors associated with abnormal ECG findings. We analyzed the data using SPSS (Version 19; IBM) statistical software. P < 0.05 was defined as statistically significant. Results: Among the 210 poisoned patients, comprising 88 men (41.9%) and 122 women (58.1%), the majority fell within the age range of 15 to 25 years. In our study, the most commonly ingested drugs by poisoned patients were amitriptyline in 134 patients (63.8%) and nortriptyline in 42 patients (20%). A significant portion of 137 patients (65.2%) exhibited poisoning symptoms within ˂ 6 hours, while 73 patients (34.8%) showed symptoms between 6 and 24 hours. Our findings indicated that the initial symptoms in poisoned patients included a decreased level of consciousness in 168 patients (80%), nausea and vomiting in 20 patients (9.5%), and various other symptoms. Notably, our results revealed ECG changes in 70 patients, with 32 patients (15.2%) showing a QRS widening (> 0.1sec), 5 patients (2.4%) displaying a tall R wave in aVR, 5 patients (2.4%) exhibiting right axis deviation, and other observed changes. Conclusion: QRS widening in poisoned patients with tricyclic antidepressants is more frequently observed in symptomatic patients, highlighting the importance of ECG screening in these patients.

RESUMO

INTRODUCTION: Antibiotics are targeted to kill or inhibit the growth of bacteria and have no effect on viral agents. Unfortunately, viruses cause about 80% of respiratory tract infections, and up to 75% of antibiotics are prescribed for URTIs. Overuse of antibiotics is linked to a number of issues, including the emergence of antibacterial resistance, an increase in the prevalence of chronic illnesses, a rise in the expense of healthcare services, and the emergence of side effects. This study aimed to assess the awareness of antibiotic misuse for URTIs among adults in the Bisha governorate in 2024. METHODS AND MATERIALS: A community-based, cross-sectional study was conducted in the Bisha governorate among the adult population. Data was collected using an online standardized self-administered adapted questionnaire. The questions vary from multiple choice to Likert scale questions, and each question has 2 points. Data was analyzed using SPSS version 26 (IBM SPSS Statistics, Armonk, NY). RESULTS: The response rate was about 85.3% (721/845). The ages of the participants ranged between 18 and 75 years. There were 360 (49.9%) male respondents and 361 (50.1%) female respondents. The study revealed that 83.1% (599) of the participants have poor awareness of antibiotic misuse in URTIs. Knowledge of antibiotic misuse consequences was poor at 66.7% (481). There was a significant difference observed between the residents of Bisha city compared to the residents of Bisha villages in total knowledge level about antibiotic misuse in URTIs (p = 0.030). CONCLUSION AND RECOMMENDATIONS: The population of the Bisha governorate has a poor knowledge of antibiotic misuse in URTIs. Therefore, efforts should be made to increase the knowledge and awareness of the general public about the problem.

RESUMO

The COVID-19 pandemic prompted adaptations to the delivery of healthcare services across Canada. In response to associated health risks and physical distancing protocols, some physicians adopted telemedicine procedures into their practice where possible. The present study aimed to investigate the impact that mode of healthcare delivery had on physicians' intention to quit their jobs due to stress, burnout, or mental health. The study utilized data collected by Statistics Canada from the Health Care Workers' Experience (SHCWEP) survey during the COVID-19 pandemic. The sample included 2,198 participants, weighted to represent 93,952 Canadian physicians aged 18 and above. Modes of healthcare delivery were categorized as either in-person, online, or blended. A multivariable logistic regression analysis was performed to examine the relationship between mode of healthcare delivery and intention to quit due to stress, burnout, or mental health, after adjusting for sociodemographic, job-, and health-related factors. Intention to quit within the next two years due to stress, burnout, or mental health was reported by 7.5% of physicians. Compared to the in-person modality, online or blended healthcare delivery was associated with decreased the odds of intention to quit (OR = 0.67, 95% CI: 0.63-0.72 and OR = 0.66, 95% CI: 0.58-0.75, respectively). The present study sheds light on factors associated with medical frontline worker well-being and retention, factors which can subsequently impact the quality of patient care. Future considerations regarding healthcare policy should incorporate strategies that protect and enhance physicians' mental health into its framework to mitigate future risks.

RESUMO

Background: Pharmaceutical companies continuously pursue healthcare professionals, starting from the medical college level, which can ultimately lead to irrational prescribing of drugs and antibiotics. Therefore, our main aim was to evaluate the opinions and attitudes of medical students toward pharmaceutical promotion. Methods: This study utilized a cross-sectional online survey that applied the snowball sampling technique. Data were collected from three public and three private sector medical colleges in Punjab, Pakistan using snowball sampling. A modified version of a pre-structured questionnaire was used to collect data between October 2020 and January 2021. Medical students from the third year onward were captivated. The tool was made available on Google Forms and students could access it by clicking the link shared. The effect of promotion on prescribing pattern and future prescribing of antibiotics were measured. Descriptive statistics, chi-square, and t-test were used to analyze the data. Results: A total of 1,301 students filled out the survey, but only 1,227 responses were acceptable. The average age was found to be 23.4 ± 1.59 years. Slightly more than half of the respondents were male participants (57.7%), and a significant proportion (84.1%) reported being aware of pharmaceutical promotion. A smaller number (27.7%) felt that physicians who meet medical representatives more frequently tend to prescribe more antibiotics and 46.3% indicated they would be willing to prescribe antibiotics under the promotional influence. Medical students who were male, in senior college years, attended government institutions, and had lower parental income showed significantly higher perception and attitude scores (p < 0.05) which, in turn, may show their inclination to promotional activities. Many students agreed with the view that pharmaceutical promotion (PP) activities may alter prescribing practices and also believed that they contribute to the increased irrational prescribing of drugs and antibiotics. Conclusion: The study revealed that only a small number of students are willing to engage in promotional activities and accept rewards, which influences their choice toward selection of drugs and antibiotics. This study highlighted the necessity of giving proper educational instructions regarding the promotion of drugs to medical students. This study also focused on the educational prerequisites of the students.

RESUMO

Background Acute decompensated heart failure (ADHF) significantly contributes to global morbidity. Stress hyperglycemia (SHGL), although commonly observed in non-diabetic ADHF patients, remains underexplored. This study investigates the predictive value of SHGL for major adverse cardiac events (MACEs) and its impact on coronary intervention outcomes. Methods In this prospective observational study at a tertiary care center, 650 non-diabetic ADHF patients admitted for coronary intervention between April 2021 and April 2022 were assessed. SHGL was defined by random blood sugar levels >140 mg/dl. We monitored the incidence of MACEs, including cardiac death, non-fatal myocardial infarction, and heart failure rehospitalization, alongside the success rates of coronary revascularizations over 12 months. Results SHGL was present in 54% of patients (n=352) and was significantly associated with increased MACEs (p<0.001), higher rehospitalization rates (p<0.01), and lower success in revascularization (p<0.05). Using logistic regression, SHGL, age >65, and prior heart failure hospitalization were identified as independent predictors of MACEs. Statistical analyses were performed using two-tailed Mann-Whitney U tests, with significance levels set at p<0.05 for noteworthy findings and p<0.01 or p<0.001 for highly significant findings. Conclusions SHGL significantly impacts coronary intervention outcomes and the future prognosis of heart failure in non-diabetic ADHF patients, identifying it as a critical, modifiable risk factor. These findings advocate integrating SHGL management into ADHF care, emphasizing the need for further research to develop standardized treatment protocols. Proper management of SHGL could potentially improve patient outcomes, highlighting the importance of metabolic control in heart failure management.

RESUMO

This systematic review aimed to explore the antimicrobial activity of a silver-containing gelling fiber dressing against multidrug-resistant organisms (MDROs) in wound infections. It particularly focuses on burn wounds and evaluates its potential clinical significance in combating antimicrobial resistance. A comprehensive literature search was conducted across multiple databases over the past ten years. It is used to identify relevant studies addressing MDRO infections in wound care and exploring novel antimicrobial approaches. The included studies underwent rigorous methodological assessment. Additionally, the data were synthesized to evaluate the efficacy of silver-containing dressings in inhibiting MDRO growth and eradicating biofilm-associated bacteria. Moreover, this review revealed that silver-containing dressings have constant in vitro antimicrobial activity against 10 MDROs over seven days in simulated wound fluid. However, inhibitory and bactericidal effects were consistently observed against free-living and biofilm phenotypes. The findings suggest potential clinical significance in managing MDRO infections in wounds. This highlights its role in mitigating treatment failure and antimicrobial resistance. Despite the promising implications for wound management practices, this study acknowledges some limitations. In vitro models and the absence of direct clinical validation have also been included. However, the review explains the importance of new approaches. Nanotechnology has been used to address antimicrobial resistance in wound care. Thus, further research and innovation are needed to improve patient outcomes and combat antimicrobial resistance.

RESUMO

<b>Background and Objective:</b> Prenatal ionizing radiation exposure may hinder fetal and embryonic growth depending on the dose and gestational age. The current study's objective was to discover how bone marrow transplants affected the spleens of pregnant rats that had been subjected to γ (Gamma) radiation. <b>Materials and Methods:</b> Sixty rats that were pregnant were separated into five different groups, each with 6 females. The pregnant rats in the second Group were exposed to 2Gy of γ-rays. Group III; pregnant rats subjected to 2Gy of γ-rays, followed by an intraperitoneal injection of newly prepared bone marrow transplantation (BMT). The fifth Group were exposed to 2Gy γ-rays and received 1 dosage of BMT an hour later. Spleen samples from the pregnant rats as well as their fetuses were taken for histological and histochemical analyses. <b>Results:</b> Gamma rays damaged the splenic tissue of women and their fetuses on days 7 or 14 of pregnancy in a variety of histological and histochemical ways, although bone marrow transplantation significantly reduced the damage. Treated mothers with bone marrow post-radiation showed a noticeable recovery in spleen of their fetuses. Improved spleen architecture was accompanied by appearance of normal content of collagen, polysaccharides and total protein in the fetal spleen tissue especially on day 7 of gestation. <b>Conclusion:</b> Bone marrow transplantation can lessen the damage caused by gamma radiation.

RESUMO

BACKGROUND: The dreaded sensation of pain in the dental chair has a significant impact on children's behavior. This study aimed to compare and contrast the perception of pain and patient behavior between the use of INJEX and the conventional syringe needle technique during pulpotomy among children. METHODS: A randomized clinical trial was designed and conducted among pediatric dentistry patients aged 6-12 years old. Fifty-eight children were divided into two groups, conventional syringe needle and INJEX, using simple randomization method applying the sequentially numbered, opaque, sealed envelope method of allocation concealment. Anesthesia was administered to the groups as local infiltration by a single operator following routine behavior guidance techniques. After 3 min, pulpotomy was performed using the standard protocol. The Face, Legs, Activity, Cry, Consolability (FLACC) scale and Wong-Baker FACES Pain Rating Scale (WBS) were used to assess the intensity of pain, while the Frankl behavior rating scale (FBRS) was used to assess the children's behavior. RESULTS: During anesthesia, most of the participants in the INJEX group (median = 3) had higher FBRS scores compared with the conventional syringe needle group (median = 2), and the difference was very highly significant (p-value < 0.001). Analyzing the FLACC scores during local anesthesia administration revealed a high statistical significance (p-value < 0.01) across the two groups. A very high statistically significant difference (p-values < 0.001) with higher WBS scores for pain intensity was seen in the group using conventional syringe needles. CONCLUSIONS: INJEX administration significantly reduced the intensity of pain experienced by the children and helped maintain a positive attitude among them during pulpotomy. It provided a positive and comfortable experience for both the child and the practitioner. Therefore, it can serve as an excellent alternative to conventional needle anesthesia.

RESUMO

Background The adoption of same-day discharge (SDD) in elective percutaneous coronary intervention (PCI) procedures offers potential benefits in terms of patient satisfaction and reduced healthcare costs. Despite these advantages, the safety and efficacy of SDD, especially among patients with diverse health profiles, are not fully understood. This study investigates the effects of patient-specific factors, including age, comorbidities, and discharge timing, on the clinical outcomes of elective PCI, focusing on the viability of SDD. Methods A prospective study was carried out at Lady Reading Hospital, Peshawar, Pakistan, involving 220 patients undergoing elective PCI from January to June 2023. This research compared the clinical outcomes of patients discharged on the same day with those who had extended hospital stays, examining the impact of age, comorbidities, and PCI success. Main outcome measures included post-procedure complications and hospital readmissions within 30 days. Results The study enrolled participants with an average age of 62 years, the majority (88%, n=194/220) of whom had comorbidities. Interestingly, 16% (n=35/220) of the participants were discharged on the same day, while the rest stayed longer in the hospital. Notably, those in the SDD group experienced significantly more complications and readmissions, with 95.14% (n=33/36) compared to only 16.22% (n=30/184) in their counterparts. Factors such as age, comorbidities, success of PCI, timing of discharge, and patient satisfaction emerged as significant predictors of the observed outcomes. Conclusion This study highlights the essential role of personalized care in discharge planning following elective PCI, advocating for a cautious approach towards SDD, especially for older patients and those with multiple health issues.

RESUMO

MXenes, a two-dimensional (2D) material, exhibit excellent optical, electrical, chemical, mechanical, and electrochemical properties. Titanium-based MXene (Ti-MXene) has been extensively studied and serves as the foundation for 2D MXenes. However, other transition metals possess the potential to offer excellent properties in various applications. This comprehensive review aims to provide an overview of the properties, challenges, key findings, and applications of less-explored vanadium-based MXenes (V-MXenes) and their composites. The current trends in V-MXene and their composites for energy storage and conversion applications have been thoroughly summarized. Overall, this review offers valuable insights, identifies potential opportunities, and provides key suggestions for future advancements in the MXenes and energy storage/conversion applications.

RESUMO

Background: Rhinitis medicamentosa is a nonallergic inflammation of the nasal mucosa caused by topical decongestants overuse. It mainly affects young and middle-aged adults. Therefore, the aim of this study was to investigate the attitudes of pharmacists regarding the utilization of over-the-counter intranasal decongestants. Methods: An online cross-sectional study was conducted from November 2021 to January 2022. The target population of the study included pharmacists who work in community pharmacies in Saudi Arabia. Binary logistic regression analysis was used to identify predictors of having positive attitude towards controlling the use of decongestant. Results: A total of 220 participants were included in this study. Around 15.0% of them reported that ND come with a physician prescription. The majority of the participants (87.3%) reported that the less than 5 days is the maximum safe duration for the use of NDs. Overall, the study participants demonstrated moderately positive attitude towards controlling the use of decongestant with a mean attitude score of 2.5 (standard deviation: 1.2) out of 5; which represents 50.0% of the maximum score. Binary logistic regression analysis identified that pharmacists aged 31-40 years were two-folds more likely to have positive attitude towards controlling the use of decongestant compared to others (p<0.05). Around 45.9% of them reported that they recommend other over-the-counter treatments like nasal irrigation, nasal steroids, or antihistamine if they see a patient with RM asking for ND with or without prescription. Conclusion: The majority of pharmacists in Saudi Arabia demonstrated sufficient awareness and understanding on the adverse effects associated with the excessive use of NDs. Rhinitis medicamentosa can be avoided by appropriate measures, highlighting the importance of raising awareness about the excessive use of decongestants among healthcare professionals and patients alike.

RESUMO

Background Contrast-induced nephropathy (CIN) significantly complicates percutaneous coronary intervention (PCI), with a higher prevalence in diabetic patients. This study compares the incidence of CIN in diabetic and non-diabetic patients undergoing PCI. Material and methods Conducted at Lady Reading Hospital, Peshawar, PAK, from January to December 2023, this observational study involved 450 adult patients with coronary artery disease (CAD) undergoing PCI. The cohort was categorized based on diabetes status, excluding patients with chronic kidney disease and those on renal replacement therapy. Baseline characteristics documented included age, gender, blood pressure, creatinine levels, and the presence of acute coronary syndrome (ACS). CIN was defined as a ≥25% increase in serum creatinine from baseline within 48-72 hours post-PCI. Data analysis was performed using the Statistical Package for the Social Sciences (IBM SPSS Statistics for Windows, IBM Corp., Version 25.0, Armonk, NY), incorporating descriptive statistics, Chi-square tests, and independent t-tests, with a significance level of p<0.05. Results The median age of the study population was 55 years. The cohort comprised 52% male (n=234) and 48% female (n=216). Notably, 33% (n=149) had ACS. Diabetic patients exhibited a significantly higher incidence of CIN post-PCI compared to non-diabetics. The highest incidence of CIN (17%, n=77) occurred in the 70+ age group. The findings highlight the criticality of renal function monitoring and procedural adjustments for diabetic patients. Conclusion Diabetic patients demonstrate an increased risk of CIN following PCI. This necessitates the development of tailored prevention strategies for this high-risk subgroup.

RESUMO

We conducted a systematic review and meta-analysis to evaluate outcomes after allogeneic hematopoietic stem cell transplantation (Allo-HSCT) in TP53-mutated myelodysplastic syndromes (MDS). A literature search was performed on PubMed, Cochrane, Embase, and Clinicaltrials.gov. After screening 626 articles, eight studies were included. Data were extracted following the PRISMA guidelines and analyzed using the meta-package by Schwarzer et al. We analyzed 540 patients. The pooled median 3 (1-5) year overall survival was 21% (95% CI 0.08-0.37, I2=91%, n=540). The pooled relapse rate was 58.9% (95% CI 0.38-0.77, I2=93%, n=487) at a median of 1.75 (1-3) years. The pooled 4-year progression- free survival was 34.8% (95% CI 0.15-0.57, I2=72%, n=105). Outcomes of Allo-HSCT for TP53-mutated MDS patients remain poor, with 21% OS at three years; however, Allo-HSCT confers a survival advantage as compared to non-transplant palliative therapies. Our findings suggest the need to explore novel therapeutic agents in prospective clinical trials.

RESUMO

OBJECTIVE: Ideal implant placement in atrophied posterior mandibular regions is challenging due to surgical difficulties and anatomical limitations. This study aimed to evaluate the use of allogeneic bone rings for vertical augmentation of atrophied posterior mandibular regions with simultaneous implants compared to autogenous bone rings, while avoiding donor site morbidity. METHOD AND MATERIALS: A total of 24 vertically atrophied posterior mandibular segments (in 14 patients) were equally randomized into a study group in which mineralized freeze-dried allogeneic bone rings were used, and a control group in which autogenous bone rings with prepared implant osteotomies were harvested from the chin and used. All augmentation sites were prepared before inserting the bone rings. Implants were simultaneously inserted, fixing the bone rings into the native bone. All patients were clinically assessed after 1 week, 2 weeks, and 1 month. Crestal bone level was radiographically assessed after 1 week, 6 months, and 3 months of prosthetic loading. RESULTS: None of the 24 bone rings showed signs of implant or graft failure. There was no significant difference in the crestal bone level between the groups. CONCLUSION: Allogeneic bone rings can be a viable alternative to autogenous bone rings in augmenting the posterior aspect of the mandible, mitigating the concerns associated with donor site complications.

RESUMO

After spinal cord injury (SCI), infiltrating macrophages undergo excessive phagocytosis of myelin and cellular debris, forming lipid-laden foamy macrophages. To understand their role in the cellular pathology of SCI, investigation of the foamy macrophage phenotype in vitro revealed a pro-inflammatory profile, increased reactive oxygen species (ROS) production, and mitochondrial dysfunction. Bioinformatic analysis identified PI3K as a regulator of inflammation in foamy macrophages, and inhibition of this pathway decreased their lipid content, inflammatory cytokines, and ROS production. Macrophage-specific inhibition of PI3K using liposomes significantly decreased foamy macrophages at the injury site after a mid-thoracic contusive SCI in mice. RNA sequencing and in vitro analysis of foamy macrophages revealed increased autophagy and decreased phagocytosis after PI3K inhibition as potential mechanisms for reduced lipid accumulation. Together, our data suggest that the formation of pro-inflammatory foamy macrophages after SCI is due to the activation of PI3K signaling, which increases phagocytosis and decreases autophagy.

RESUMO

The reproductive microbiota of male dogs has never been investigated using culture-independent sequencing techniques. The purpose of the present study was to get seminal knowledge on the microbiota of the ejaculate. Specifically, factors as the fraction of the ejaculate, the sperm quality (normospermia, teratozoospermia), and the living environment were evaluated. The sperm-rich and the prostatic fractions of the ejaculate were collected from healthy stud dogs. Following the sperm analysis, samples from twenty animals (normospermic n = 10 and teratozoospermic n = 10) were stored at - 80 °C until further processing including DNA extraction and 16S rRNA sequencing. Alpha- (Shannon index) and beta- (Bray-Curtis, Unweighted UniFrac) diversities were assessed and compared (PERMANOVA) based on the group of samples (biological samples from the ejaculate and controls), the fraction of the ejaculate (sperm-rich and prostatic fractions), the animal group (normospermia and teratozoospermia), and the living environment of the animal (kennel or pet living in-house). The most abundant bacterial phyla in canine semen samples were Proteobacteria, Firmicutes, and Actinobacteria. Overall, the dominant bacterial family was that of Pasteurellaceae The genus Mycoplasma was never detected. No differences in terms of bacterial composition were found based on the fraction of the ejaculate and based on the animal group (P > 0.05). On the other hand, differences in alpha and beta diversities were highlighted based on the living environment (P = 0.001). Overall, the results of the present study provide preliminary insights on dog semen microbiota, opening a new chapter in the field of canine andrology. Our results suggest that the environment may play a role in influencing the reproductive microbiota of male dogs and that the prostatic fraction of the ejaculate can be used for further research as a representative of the semen microbiota.

RESUMO

The COVID-19 pandemic resulted in a major shift in the delivery of healthcare services with the adoption of care modalities to address the diverse needs of patients. Besides, nurses, the largest profession in the healthcare sector, were imposed with challenges caused by the pandemic that influenced their intention to leave their profession. The aim of the study was to examine the influence of mode of healthcare delivery on nurses' intention to quit job due to lack of satisfaction during the pandemic in Canada. This cross-sectional study utilized data from the Health Care Workers' Experiences During the Pandemic (SHCWEP) survey, conducted by Statistics Canada, that targeted healthcare workers aged 18 and over who resided in the ten provinces of Canada during the COVID-19 pandemic. The main outcome of the study was nurses' intention to quit within two years due to lack of job satisfaction. The mode of healthcare delivery was categorized into; in-person, online, or blended. Multivariable logistic regression was performed to examine the association between mode of healthcare delivery and intention to quit job after adjusting for sociodemographic, job-, and health-related factors. Analysis for the present study was restricted to 3,430 nurses, weighted to represent 353,980 Canadian nurses. Intention to quit job, within the next two years, due to lack of satisfaction was reported by 16.4% of the nurses. Results showed that when compared to participants who provided in-person healthcare services, those who delivered online or blended healthcare services were at decreased odds of intention to quit their job due to lack of job satisfaction (OR = 0.47, 95% CI: 0.43-0.50 and OR = 0.64, 95% CI: 0.61-0.67, respectively). Findings from this study can inform interventions and policy reforms to address nurses' needs and provide organizational support to enhance their retention and improve patient care during times of crisis.

RESUMO

Street children are particularly susceptible to health-related adversities, including those resulting from substance abuse and child abuse. Information on street children is deficient in Sudan. This study provides basic data on characteristics, factors for leaving home, the pattern of child abuse and substance misuse among street children in Khartoum State, Sudan. This is a descriptive, cross-sectional, and community-based study. Data were collected through direct questioning of a sample of street children using a structured, standardized, and pretested interview-administered questionnaire. Two hundred and seventy-five (275) street children were interviewed. Most street children were males (83%). Of the interviewed children, 36.7% were illiterate, 66.1% had a single parent, and 36% did not recognize a home to return to. The commonest reported reasons for being on the streets were family conflicts and financial/economic difficulties (28.4 % and 27.5%), respectively. 89.1% of the children admitted to being substance abusers, mostly of glue (86.5%) and smoked tobacco (67.3%). Seventy-five-point three percent 75.3% of the children reported being subjected to a form of abuse, with physical and sexual abuse reported by 70.2% and 27%, respectively. Of the 74 children who reported sexual abuse, 49 were males (29% of males), and 25 were females (65% of females). The survey results are thought to guide further research and shape appropriate policymaking and coordinated interventions by concerned stakeholders, whether governmental or non-governmental.
