RESUMO
Efficient treatment of cancer has been a subject of research by scientists for many years. Current treatments for cancer, such as radiotherapy, chemotherapy and surgery have been used in traditional combination therapy, but they have major setbacks like non-specificity, non-responsiveness in certain cancer types towards treatment, tumor recurrence, etc. Epidemiological data has shown that breast cancer accounts for 14% of cancer cases occurring in Indian women. In recent years, scientists have started to focus on the use of natural compounds like lectins obtained from various sources to counter the side effects of traditional therapy. Lectins like Sambucus nigra Agglutinin, Maackia amurensis lectin, Okra lectins, Haliclona caerulea lectin, Sclerotium rolfsii lectin, etc., have been discovered to have both diagnostic and therapeutic potential for breast cancer patients. Lectins have been found to have inhibitory effects on various cancer cell activities such as neo-angiogenesis, causing cell cycle arrest at the G1 phase, and inducing apoptosis. The major idea behind the use of lectins in cancer diagnostics and therapeutics is their capability to bind to glycosylated proteins that are expressed on the cell surface. This review focuses on an exploration of the roles of post-translational modification in cancer cells, especially glycosylation, and the potential of lectins in cancer diagnosis and therapeutics.

Studies focusing on the safety and common side effects of vaccines play a crucial role in enhancing public acceptance of vaccination. Research is scarce regarding the usage of COVID-19 vaccines and the side effects experienced by health professions students in India and other countries. This study aimed to document self-reported side effects associated with COVID-19 vaccination among medical and dental students of six medical and dental colleges and teaching hospitals in four states (Tamil Nadu, Madhya Pradesh, Gujarat, and West Bengal) of India. A cross-sectional survey using purposive sampling of medical and dental students was conducted from 26 April to 26 May 2021. Data was collected using a Google Forms questionnaire capturing information regarding receiving COVID-19 vaccines, side effects and symptoms, onset and duration of symptoms, use of treatment to alleviate symptoms, awareness of haematologic risks associated with vaccination, and side effects from previous (non-COVID-19) vaccinations. The majority (94.5%) of participants received both doses of the Covishield/AstraZeneca COVID-19 vaccine. Among participants (n = 492), 45.3% (n = 223) reported one or more side effects. The most frequently reported side effects were soreness of the injected arm (80.3%), tiredness (78.5%), fever (71.3%), headache (64.1%), and hypersomnia (58.7%). The two most common severe symptoms were fever (14.8%) and headache (13%). Most side effects appeared on the day of vaccination: soreness of the injection site (57%), fever (43.1%), and tiredness (42.6%). Most reported symptoms persisted for one to three days-soreness of the injection site (53%), fever (47.1%), and headache (42.6%). Logistic regression showed that women were almost 85% less likely to report side effects. The study's findings corroborate the safety of the Covishield/AstraZeneca vaccine's first dose, evidenced by the relatively minor and transient nature of the side effects. However, the study underscores the necessity for ongoing research to assess the long-term impacts of COVID-19 vaccines, especially in the context of booster doses, thereby contributing to the global understanding of vaccine safety and efficacy.

Background: Efficacy and safety are fundamental for the development of successful COVID-19 vaccines. Vaccine-associated side effects influence vaccine hesitancy. This study investigated the prevalence, severity, and onset of side effects following the first dose of COVID-19 vaccines among physicians and dentists working in various healthcare settings across India. Methods: A cross-sectional survey collected self-report data from April to June 2021 on side effects following the first dose of the vaccine. An online validated questionnaire using the Google Docs® platform was circulated via email and social media platforms. Results: More than 40% of participants experienced at least one side effect after the first dose of vaccination; the most common were mild and resolved within three days after vaccination. More than 91% of respondents received the Covishield (AstraZeneca) vaccine; the most prevalent adverse effects were soreness of the injected arm (78.9%), tiredness (71.1%), and fever (54.9%). Logistic regression showed that women were almost 60% less likely to report side effects. Conclusion: Findings supported the safety of the first dose of the COVID-19 vaccine based on relatively few self-limiting side effects, mainly soreness of the injected arm and tiredness. Further research is needed to determine the long-term safety of COVID-19 vaccines, especially after booster doses.
RESUMO
INTRODUCTION: Implementation research with pre- and post-comparison was planned to improve the quality of evidence-based intrapartum care services in Indian medical schools. We present the baseline study results to assess the status of adherence to intrapartum evidence-based practices (IP-EBP) in study schools in 3 states in India and the perception of the faculty. METHODS: A concurrent mixed-methods approach was used to conduct the baseline assessment in 9 medical schools in Rajasthan, Gujarat, and Union Territory from October 2018 to June 2019. IP-EBP among pregnant women in uncomplicated first (n=135), second (n=120), and third stage (n=120) of labor were observed using a predesigned, pretested checklist quantitatively. We conducted in-depth interviews with 33 obstetrics and gynecology faculty to understand their perceptions of intrapartum practices. Quantitative data were analyzed using SPSS (version 22). COM-B (Capability, Opportunity, and Motivation Behavior) model was used to understand the behaviors, and thematic analysis was done for the qualitative data. FINDINGS: Unindicated augmentation of labor was done in 64.4%, fundal pressure applied in 50.8%, episiotomy done in 58.3%, and delivery in lithotomy position was performed in 86.7% of women in labor. CONCLUSIONS: Intrapartum practices that are not recommended were routinely practiced in the study medical schools due to a lack of staff awareness of evidence-based practices and incorrect beliefs about their impact.

The assisted reproductive technology (ART) laboratory is a complex system designed to sustain the fertilization, survival, and culture of the preimplantation embryo to the blastocyst stage. ART outcomes depend on numerous factors, among which are the equipment, supplies and culture media used. The number and type of incubators also may affect ART results. While large incubators may be more suitable for media equilibration, bench-top incubators may provide better embryo culture conditions in separate or smaller chambers and may be coupled with time-lapse systems that allow continuous embryo monitoring. Microscopes are essential for observation, assessment, and micromanipulation. Workstations provide a controlled environment for gamete and embryo handling and their quantity should be adjusted according to the number of ART cycles treated in order to provide a steady and efficient workflow. Continuous maintenance, quality control and monitoring of equipment are essential and quality control devices such as the thermometer, and pH-meter are necessary to maintain optimal culture conditions. Tracking, appropriate delivery and storage conditions, and quality control of all consumables are recommended so that adequate quantity and quality are available for use. Embryo culture media have evolved: preimplantation embryos are cultured either by sequential media or single-step media that can be used for interrupted or uninterrupted culture. There is currently no sufficient evidence that any individual commercially-available culture system is better than others in terms of embryo viability. In this review, we aim to analyze the various parameters that should be taken into account when choosing the essential equipment, consumables and culture media systems that will create optimal culture conditions and provide the most effective patient treatment.

Oocyte retrieval, oocyte denudation, and embryo transfer are crucial processes during assisted reproduction technology (ART). Air quality in the ART laboratory, temperature, pH of the media used and the time interval between oocyte retrieval and insemination are all critical factors. Anesthesia is required for oocyte retrieval, however, evidence regarding the potential impact of different methods (general anesthesia, conscious sedation, and local anesthesia) on the clinical outcomes is unclear. The optimal timing of oocyte denudation following retrieval has not been established. Regarding the mechanical denudation process, there is a lack of evidence to demonstrate the safest minimum inner diameter of denuding pipettes used to complete the removal of granulosa cells surrounding the oocytes. During embryo transfer, many clinics worldwide flush the catheter before embryo loading, in an attempt to potentially rinse off any toxic agents; however, there is insufficient evidence to show that flushing the embryo transfer catheter before loading increases the success of ART outcome. Considering the serious gaps in knowledge in ART practice, the aim of this review is to provide an updated overview of the current knowledge regarding the various steps and techniques involved in oocyte retrieval, oocyte denudation, and embryo loading for transfer.

With the advance of assisted reproduction techniques, and the trend towards blastocyst culture and single embryo transfer, gamete and embryo assessment have gained greater importance in ART treatment. Embryo quality depends mainly on gamete quality and culture conditions. Oocyte maturity identification is necessary in order to plan fertilization timing. Mature oocytes at the metaphase II stage show a higher fertilization rate compared to immature oocytes. Morphology assessment is a critical yet challenging task that may serve as a good prognostic tool for future development and implantation potential if done effectively. Various grading systems have been suggested to assess embryos at pronuclear, cleavage, and blastocyst stages. By identifying the embryo with the highest implantation potential, it is possible to reduce the number of embryos transferred without compromising the chances of a successful pregnancy. Apart from the conventional morphology assessment, there are several invasive or non-invasive methods for embryo selection such as preimplantation genetic testing, morphokinetics, proteomics, metabolomics, oxygen consumption, and measurement of oxidative stress in culture medium. Morphokinetics is a method based on time-lapse technology and continuous monitoring of embryos. In this review, we aimed to describe and compare the most effective and widely used methods for gamete and embryo assessment as well as embryo selection.

Retrograde ejaculation (RE) is a condition defined as the backward flow of the semen during ejaculation, and when present can result in male infertility. RE may be partial or complete, resulting in either low seminal volume or complete absence of the ejaculate (dry ejaculate). RE can result from anatomic, neurological or pharmacological conditions. The treatment approaches outlined are determined by the cause. Alkalinizing urinary pH with oral medications or by adding sperm wash media into the bladder prior to ejaculation may preserve the viability of the sperm. This article provides a step-by-step guide to diagnose RE and the optimal techniques to retrieve sperm.
RESUMO
Radiology education and training is of paramount clinical importance given the prominence of medical imaging utilization in effective clinical practice. The incorporation of basic radiology in the medical curriculum has continued to evolve, focusing on teaching image interpretation skills, the appropriate ordering of radiological investigations, judicious use of ionizing radiation, and providing exposure to interventional radiology. Advancements in radiology have been driven by the digital revolution, which has, in turn, had a positive impact on radiology education and training. Upon the advent of the corona virus disease 2019 (COVID-19) pandemic, many training institutions and hospitals adhered to directives which advised rescheduling of non-urgent outpatient appointments. This inevitably impacted the workflow of the radiology department, which resulted in the reduction of clinical in-person case reviews and consultations, as well as in-person teaching sessions. Several medical schools and research centers completely suspended face-to-face academic activity. This led to challenges for medical teachers to complete the radiology syllabus while ensuring that teaching activities continued safely and effectively. As a result, online teaching platforms have virtually replaced didactic face-to-face lectures. Radiology educators also sought other strategies to incorporate interactive teaching sessions while adopting the e-learning approach, as they were cognizant of the limitations that this may have on students' clinical expertise. Migration to online methods to review live cases, journal clubs, simulation-based training, clinical interaction, and radiology examination protocolling are a few examples of successfully addressing the limitations in reduced clinical exposure. In this review paper, we discuss (1) The impact of the COVID-19 pandemic on radiology education, training, and practice; (2) Challenges and strategies involved in delivering online radiology education for undergraduates and postgraduates during the COVID-19 pandemic; and (3) Difference between the implementation of radiology education during the COVID-19 pandemic and pre-COVID-19 era.
RESUMO
Background The newly developed coronavirus disease 2019 (COVID-19) vaccines are considered to be a powerful tool to contain the devastating pandemic. Healthcare workers (HCWs) are at the highest risk of exposure to COVID-19 and, therefore, they are the priority group for vaccination. Objectives The study aimed to examine the perceptions, attitudes, and acceptability of the COVID-19 vaccination among HCWs in India. Study design A cross-sectional pilot survey was conducted using an online questionnaire between 13 and 25 January 2021. Results Among 264 respondents, 40.2% of HCWs would receive the vaccine against COVID-19 if available and 32.2% were willing to take the vaccine after observing adverse effects in others. Infected members in the immediate social network (OR:2.15; 95%CI:0.426-10.844), COVID-19 knowledge (OR:5.113; 95%CI:0.974-26.853), the safety of vaccines (OR:7.608; 95%CI:2.618-22.11), and those who did not receive a flu vaccine last year (OR:2.612; 95%CI:1.120-6.091) were found to have a statistically significant association with vaccine acceptance. The main reasons to delay/refuse vaccination included: 'quick vaccine development and compromised quality' (43.7%) and 'lack of trusted information regarding COVID-19' (41.3%). Conclusions The finding showed a high rate of vaccine hesitancy among HCWs. Policymakers should take steps to increase public awareness and secure timely and affordable vaccines for the HCWs and general population with effective vaccine promotion campaigns.
RESUMO
BACKGROUND: Biomedical research and publications provide evidence-based information about the extent and burden of health-related problems of a country and help to formulate strategic and operational plans to tackle the problems. PURPOSE: To determine the biomedical publication rates of CARICOM full member countries. METHODS: Biomedical publications of full member CARICOM countries were retrieved using PubMed (1990-2015) and SCImago Journal & Country Rank (1996-2015) databases. CARICOM countries having >50 publications in the PubMed (1990-2015) database were subject to further analysis, whereby publications of each country were adjusted by total population (million population), gross domestic product (billion-dollar), and Internet usage rate (hundred thousand population). RESULTS: Total publications by all countries were 7281 and 8378 in PubMed and SCImago Journal & Country Rank, respectively. Jamaica produced highest number of publications (PubMed: 3928 (53.9%); SCImago Journal & Country Rank: 2850 (34.0%)). In both databases, Grenada had the highest research publications when adjusted with per million population (4721 and 10,633), per billion gross domestic product (803 and 1651), and per hundred thousand Internet users (1487 and 3387). Trend analysis revealed Jamaica produced the highest number of additional PubMed listed publications each year, averaging 4.8/year, followed by Trinidad and Tobago (4.4). According to SCImago Journal & Country Rank, Jamaica also had the highest number of citations (42,311) and h-index (76), followed by Trinidad and Tobago (29,152 and 71). Barbados had the highest number of citations per document (24.9), followed by Haiti (18.4). The publication rates determined by PubMed and SCImago Journal & Country Rank databases were significantly correlated (p < 0.001). Most publications (68% SCImago Journal & Country Rank and 85% PubMed) can be attributed to authors affiliated with Barbados, Jamaica, and Trinidad. CONCLUSION: Publication and citation rates varied markedly between CARICOM countries and were in general low. Most publications could be attributed to researchers affiliated with The University of the West Indies. More universities valuing biomedical research are needed in the region, and more resources needed to improve publication rates.
RESUMO
BACKGROUND: Technology-enhanced learning includes the adaptive e-learning platform, a data-driven method with computer algorithms, providing customised learning enhancing critical thinking of individual learners. "Firecracker" - an online adaptive e-learning platform, and assessment software, promotes critical thinking, helps prepare students for courses and high-stakes examinations, and evaluates progress relative to co-learners. The objectives of this study were to determine the usage rates of Firecracker, examine the performance of Firecracker formative quizzes, identify the correlation between Firecracker use and performance with that of performance at summative course assessments, and assess students' satisfaction with Firecracker usage. METHODS: Study participants were Year-2 MBBS (Bachelor of Medicine, Bachelor of Surgery) students (n=91) of the Faculty of Medical Sciences, The University of the West Indies, Cave Hill Campus, Barbados. The Firecracker Administrator uploaded quizzes covering basic science content in the Cardiovascular System course. Access, usage, and performance on Firecracker formative quizzes were retrieved from the Firecracker dashboard. A questionnaire sought the views of study participants. RESULTS: Seven sets of quizzes were administered over nine weeks, with weekly student completion rates ranging from 53% to 73%. Mean quiz scores ranged from 52% to 72%. Students completing >4 quiz sessions compared to those completing ≤4 demonstrated significantly better performance in Firecracker quizzes (P<0.01), final examinations (P<0.01) and in-course assessment plus final examination (P<0.05) scores. Correlations between overall Firecracker performance and in-course assessment marks (P<0.05); between total overall Firecracker performance and final examination (P<0.01); and overall Firecracker performance and total course marks (P<0.01) were all significant. Most students (70%) were happy using Firecracker and felt it complemented coursework (78%) and prepared them for course exams (58%) (P<0.01). CONCLUSION: Overall, Firecracker was perceived very positively and welcomed by the students. Students were satisfied with the Firecracker as a formative assessment tool, and its use correlated with improved performance in the course examinations.
RESUMO
COVID-19 pandemic is inducing acute respiratory distress syndrome, multi-organ failure, and eventual death. Respiratory failure is the leading cause of mortality in the elderly population with pre-existing medical conditions. This group is particularly vulnerable to infections due to a declined immune system, comorbidities, geriatric syndrome, and potentially inappropriate polypharmacy. These conditions make the elderly population more susceptible to the harmful effects of medications and the deleterious consequences of infections, including MERS-CoV, SARS-CoV, and SARS-CoV-2. Chronic diseases among elderlies, including respiratory diseases, hypertension, diabetes, and coronary heart diseases, present a significant challenge for healthcare professionals. To comply with the clinical guidelines, the practitioner may prescribe a complex medication regimen that adds up to the burden of pre-existing treatment, potentially inducing adverse drug reactions and leading to harmful side-effects. Consequently, the geriatric population is at increased risk of falls, frailty, and dependence that enhances their susceptibility to morbidity and mortality due to SARS-CoV-2 respiratory syndrome, particularly interstitial pneumonia. The major challenge resides in the detection of infection that may present as atypical manifestations in this age group. Healthy aging can be possible with adequate preventive measures and appropriate medication regimen and follow-up. Adherence to the guidelines and recommendations of WHO, CDC, and other national/regional/international agencies can reduce the risks of SARS-CoV-2 infection. Better training programs are needed to enhance the skill of health care professionals and patient's caregivers. This review explains the public health implications associated with polypharmacy on the geriatric population with pre-existing co-morbidities during the COVID-19 pandemic.
RESUMO
COVID-19 pandemic has disrupted face-to-face teaching in medical schools globally. The use of remote learning as an emergency measure has affected students, faculty, support staff, and administrators. The aim of this narrative review paper is to examine the challenges and opportunities faced by medical schools in implementing remote learning for basic science teaching in response to the COVID-19 crisis. We searched relevant literature in PubMed, Scopus, and Google Scholar using specific keywords, e.g., "COVID-19 pandemic," "preclinical medical education," "online learning," "remote learning," "challenges," and "opportunities." The pandemic has posed several challenges to premedical education (e.g., suspension of face-to-face teaching, lack of cadaveric dissections, and practical/laboratory sessions) but has provided many opportunities as well, such as the incorporation of online learning in the curriculum and upskilling and reskilling in new technologies. To date, many medical schools have successfully transitioned their educational environment to emergency remote teaching and assessments. During COVID-19 crisis, the preclinical phase of medical curricula has successfully introduced the novel culture of "online home learning" using technology-oriented innovations, which may extend to post-COVID era to maintain teaching and learning in medical education. However, the lack of hands-on training in the preclinical years may have serious implications on the training of the current cohort of students, and they may struggle later in the clinical years. The use of emergent technology (e.g., artificial intelligence for adaptive learning, virtual simulation, and telehealth) for education is most likely to be indispensable components of the transformative change and post-COVID medical education.
RESUMO
INTRODUCTION: Antimicrobial resistance poses a serious threat to global health with significantly higher morbidity, mortality, and economic burden. This review aims to discuss the importance of the promotion of antimicrobial stewardship in medical and allied health professional curricula and training/educating tomorrow's doctors in combatting antimicrobial resistance. A narrative literature review was conducted to retrieve relevant information related to antimicrobial resistance and stewardship and their implications on medical and allied health professional education and training from searches of computerized databases, hand searches, and authoritative texts. AREAS COVERED: Antimicrobial stewardship programs improve rational antibiotic use, reduce antimicrobial resistance, decrease complications of antibiotic use, and improve patient outcomes. Though health professional students recognize the importance and impact of antibiotic prescribing knowledge, many studies have consistently demonstrated low levels of confidence and competencies amongst students, highlighting that health professional schools failed to prepare them to prescribe antibiotics accurately. EXPERT OPINION: There is an urgent call for the integration of antimicrobial stewardship teaching at the undergraduate level of medical education to train future prescribers on this critical aspect of public health. Proper undergraduate education on rational antibiotics use would enable health professional graduates to enter clinical practice with adequate competencies to become rational prescribers.

Antimicrobial resistance (AMR) is a serious threat to global public health. It increases morbidity and mortality, and is associated with high economic costs due to its health care burden. Infections with multidrug-resistant (MDR) bacteria also have substantial implications on clinical and economic outcomes. Moreover, increased indiscriminate use of antibiotics during the COVID-19 pandemic will heighten bacterial resistance and ultimately lead to more deaths. This review highlights AMR's scale and consequences, the importance, and implications of an antimicrobial stewardship program (ASP) to fight resistance and protect global health. Antimicrobial stewardship (AMS), an organizational or system-wide health-care strategy, is designed to promote, improve, monitor, and evaluate the rational use of antimicrobials to preserve their future effectiveness, along with the promotion and protection of public health. ASP has been very successful in promoting antimicrobials' appropriate use by implementing evidence-based interventions. The "One Health" approach, a holistic and multisectoral approach, is also needed to address AMR's rising threat. AMS practices, principles, and interventions are critical steps towards containing and mitigating AMR. Evidence-based policies must guide the "One Health" approach, vaccination protocols, health professionals' education, and the public's awareness about AMR.
RESUMO
BACKGROUND: Various evidence-based and student-centered strategies such as team-based learning (TBL), case-based learning (CBL), and flipped classroom have been recently applied to anatomy education and have shown to improve student engagement and interaction. These strategies shift the focus of teaching from knowledge transmission to knowledge construction by students and encourage the use of tasks. This study discusses the use of an active and engaging learning strategy to teach the musculoskeletal system to Year 1 MBBS students (Faculty of Medical Sciences, The University of the West Indies, Cave Hill, Barbados) and examines the correlation between assessment modalities and student performance. METHODS: The "Active and Engaging Learning Strategy" was used to assess student learning in the form of oral presentations. Students had presentations on muscle attachments, muscle actions, blood and nerve supply, and applied anatomy of the limb musculature. Questions on the limbs (Locomotor System) were included in pre and post-presentation spotters, in-course assessments, and final examinations. Percentages, paired t-test, independent sample t-test, and zero-order correlations were performed to confirm the results for the different objectives of the study. RESULTS: The main modes of presentation chosen were poems (37.1%), followed by stories (21.2%), songs (11.4%), and skits (10.6%). The majority of students (84%) found the strategies beneficial and recommended such sessions for future cohorts (92%). Students achieved significantly better scores in post-presentation spotters (p < 0.01) and the marks of in-course and final examinations also showed significant improvement (p < 0.01). CONCLUSION: Our study highlighted that the active and engaging learning strategy can be used as an effective learning tool in anatomy. Students were proactive in preparing the muscle presentations by utilizing their own creativity, curiosity, and intelligence. Further studies should be conducted using randomized controlled trials to assess the effectiveness of various learning strategies which could open a new door to medical education.

BACKGROUND: Ensuring objectivity and maintaining reliability are necessary in order to consider any form of assessment valid. Evaluation of students in Problem-Based Learning (PBL) tutorials by the tutors has drawn the attention of critiques citing many challenges and limitations. The aim of this study was to determine the extent of tutor variability in assessing the PBL process in the Faculty of Medical Sciences, The University of the West Indies, St Augustine Campus, Trinidad and Tobago. METHOD: All 181 students of year 3 MBBS were assigned randomly to 14 PBL groups. Out of 18 tutors, 12 had an opportunity to assess three groups: one assessed 2 groups and 4 tutors assessed one group each; at the end each group had been assessed three times by different tutors. The tutors used a PBL assessment rating scale of 12 different criteria on a six-point scale to assess each PBL Group. To test the stated hypotheses, independent t-test, one-way ANOVA followed by post-hoc Bonferroni test, Intra Class Correlation, and Pearson product moment correlations were performed. RESULT: The analysis revealed significant differences between the highest- and lowest-rated groups (t-ratio = 12.64; p < 0.05) and between the most lenient and most stringent raters (t-ratio = 27.96; p < 0.05). ANOVA and post-hoc analysis for highest and lowest rated groups revealed that lenient- and stringent-raters significantly contribute (p < 0.01) in diluting the score in their respective category. The intra class correlations (ICC) among rating of different tutors for different groups showed low agreement among various ratings except three groups (Groups 6, 8 and 13) (r = 0.40). The correlation between tutors' PBL experiences and their mean ratings was found to be moderately significant (r = 0.52; p > 0.05). CONCLUSION: Leniency and stringency factors amongst raters affect objectivity and reliability to a great extent as is evident from the present study. Thus, more rigorous training in the areas of principles of assessment for the tutors are recommended. Moreover, putting that knowledge into practice to overcome the leniency and stringency factors is essential.

This study describes the prevalence and patterns of major congenital malformations of the musculoskeletal system and the resulting morbidity and mortality. It is a retrospective population-based study over the period 1993 to 2012. The overall prevalence of major congenital malformations of the musculoskeletal system was 9.02/10,000 live births. The prevalences of omphalocele, gastroschisis, and diaphragmatic hernia were 2.53, 2.22, and 1.42 per 10,000 live births, respectively. The case fatality ratio for the omphalocele, gastroschisis, and diaphragmatic hernia was 12.5, 28.5, and 67%, respectively. In conclusion, the prevalence rate of the major congenital malformations of the musculoskeletal system was higher than those reported in retrospective studies from other countries and remained static during the study period. These defects were associated with a high mortality rate and contributed significantly to the overall neonatal mortality in this country.
RESUMO
BACKGROUND: The major objectives of this study were to evaluate the existing primary health care service provisions in the public and private sector and utilization of the services, and to assess the existing manpower and material resources. METHODS: Data were collected through interviews with the primary health care providers. Data were also collected from the records maintained at the polyclinics and the Ministry of Health Statistics. An analysis and discussion of all the available data was conducted to develop a comprehensive primary health care service utilization and resources inventory at the polyclinics. Similar data were collected from the primary care providers in the private sector. RESULTS: In the public sector, there are 8 polyclinics that provide primary health care to the children. All the polyclinics have immunization services and curative acute care. Some of the polyclinics have a range of services, including dental care, eye care, and rehabilitative care services that common to both adults and children. In the private sector, primary health care is delivered through the 76 private office and of the individual physicians and 11 grouped private practices. All of the private offices and group practices have curative acute care for children and some of the offices have immunization services. Over all 87.5% of all the immunizations were done at the polyclinics. Over all 60.1% of acute care visits were to the private sector and 39.9% to the public sector. In the public sector, 59.5% were under 5 years children while 40.5% were 5 years or older. The corresponding figures in the private care settings were 80.9% and 11.9%. CONCLUSIONS: The findings demonstrate the complimentary role of the public and the private sector in the primary health care of children in this country. While the private sector has a major role in the curative acute care of children, the public sector plays a pivotal role in the immunization services.
