RESUMEN

The achievement of Universal Health Coverage (UHC) requires equitable access and utilization of healthcare services across all population groups, including men. However, men often face unique barriers that impede their engagement with health systems which are influenced by a myriad of socio-cultural, economic, and systemic factors. Therefore, understanding men's perspectives and experiences is crucial to identifying barriers and facilitators to their healthcare-seeking behaviour under UHC initiatives. This qualitative study sought to explore men's perceptions, experiences, healthcare needs and potential strategies to inform an impartial implementation of Universal Health Coverage (UHC) in Kenya. The study employed a qualitative research design to investigate men's healthcare experiences in 12 counties across Kenya. Thirty focus group discussions involving 296 male participants were conducted. Men were purposively selected and mobilized through the support of health facility-in-charges, public health officers, and community health extension workers. Data was coded according to emergent views and further categorized thematically into three main domains (1) Perspectives and experiences of healthcare access (2) Socio-cultural beliefs and societal expectations (3) Desires and expectations of health systems. Findings revealed complex sociocultural, economic, and health system factors that influenced men's healthcare experiences and needs which included: masculinity norms and gender roles, financial constraints and perceived unaffordability of services, lack of male-friendly and gender-responsive healthcare services, confidentiality concerns, and limited health literacy and awareness about available UHC services. Our study has revealed a disconnect between men's needs and the current healthcare system. The expectations concerning masculinity further exacerbate the problem and exclude men further hindering men's ability to receive appropriate care. This data provides important considerations for the development of comprehensive and gender-transformative approaches challenging harmful masculine norms, pushing for financial risk protection mechanisms and gender-responsive healthcare delivery attuned to the unique needs and preferences of men.

RESUMEN

BACKGROUND: Anemia remains a major global public health issue, affecting around 24.8% of the world's population in both developing and developed countries. Pregnant women in developing countries are particularly susceptible, with 38.2% affected worldwide. Anemia is also a major contributor to maternal mortality, with 510,000 maternal deaths globally, of which 20% occur in developing countries and are related to anemia. Iron deficiency anemia is the most prevalent form, impacting 1.3 to 2.2 billion individuals, with 50% being women of reproductive age. AIM: This study aimed to assess the prevalence and associated factors of anemia in pregnant women attending antenatal care (ANC) at Hargeisa Group Hospital (HGH), Somaliland. METHODS: A cross-sectional study included 360 pregnant women, who sought ANC at HGH from July 15 to August 6, 2023. The study subjects were selected using systematic random sampling. Data were collected through structured questionnaires and participants' current medical charts, including hemoglobin levels. Data analysis was performed using SPSS software (version 20). RESULTS: The study revealed an overall prevalence of anemia among pregnant women at 50.6% (95% CI: 45.40 - 55.72%). Anemia severity was categorized as mild (33.0%), moderate (54.9%), and severe (12.1%). Factors statistically associated with anemia included gestational age in the third trimester (AOR = 3.248, 95% CI: 1.491-7.074), lack of ANC visits (AOR = 6.828, 95% CI: 1.966-23.721), and absence of iron supplementation (AOR = 29.588, 95% CI: 2.922-299.713). Notably, a higher consumption of meat per week was associated with a reduced risk of anemia (AOR = 0.198, 95% CI: 0.104-0.379). CONCLUSION: The study underscores the severity of anemia in pregnant women within the range considered as severe public health problem by WHO. It is crucial to emphasize effective prenatal care, improve dietary practices, and promote the provision of iron supplements. Enhanced maternal education on Anemia during ANC visits has the potential to reduce Anemia prevalence and mitigate adverse maternal and neonatal outcomes.

RESUMEN

Plantar warts are common skin lesions that continue to represent a therapeutic challenge. They are still resistant to therapy and are highly recurrent, despite the diverse number of treatments available. Therapies targeting vasculature, such as pulsed dye laser, have been used successfully in the treatment of plantar warts. Polidocanol, a detergent sclerosant approved for the sclerotherapy of incompetent and dilated saphenous veins, has also been used as an off-label therapy for a wide range of skin conditions with vascular components such as hemangiomas and pyogenic granuloma. The current, open-label, prospective, pilot study aimed to evaluate the safety and efficacy of the intralesional polidocanol 3% in the treatment of plantar warts. Twenty patients (11 females and 9 males), with plantar warts, aged 12-50 years received biweekly sessions of intralesional polidocanol 3% until complete clearance or for a maximum of 6 sessions. Response to treatment was graded as complete (100% clearance), partial (50-99%), and no response (< 50%). At the end of the study, 12 (60%) patients achieved complete clearance of their warts after 1-5 sessions, 5 (25%) patients had only partial response, and 3 (15%) patients did not achieve any clearance of their warts. The procedure was largely tolerable by patients. Pain at the injection site and bruises were reported by 9 (45%) and 2 (10%) patients, respectively. Both side effects resolved spontaneously and completely within a few days. The findings of the current study suggest that intralesional injection of 3% polidocanol in biweekly sessions may be a safe, effective, and tolerable method for the treatment of plantar warts.

RESUMEN

Objective: Different anaesthetists for sedation or monitored anaesthesia care have been used for colonoscopy. The target of this research was the ability to perform colonoscopy under a painless degree of sedation and the prevalence of undesired proceedings. Methods: A total of 60 patients were randomly divided into two groups: Group D received dexmedetomidine and Group PF received propofol-fentanyl. Patients in both groups received the same infusion ratio. The minimum infusion amount of dexmetatomidine is (0.1 to 0.4 µg kg-1 h-1) in Group D, whereas fentanyl is administered at a rate of 0.01 to 0.05 µg kg-1 min-1 in the PF group during the approximately 45-min colonoscopy. Results: Group D exhibited significantly lower modified Observer's Assessment of Alertness/Sedation (OAA/S) scores at intraoperative time points T1-T12. Group D also exhibited significantly lower visual analog scale scores for pain at intraoperative time points T4 and T7. The mean arterial pressure was significantly lower in Group D at intraoperative times T6-T8 and T11-T12, as well as upon admission to the post-anaesthesia care unit (PACU) and 30 min after admission to the PACU. The results of the ANOVA tests revealed a significantly lower heart rate in Group D. The respiratory rate exhibited a notable decrease during time intervals T8 and T10 in the PF group. Conclusion: The administration of dexmetatomidine and propofol-fentanyl during colonoscopy was found to be safe. In addition, dexmetatomidine may present significant benefits in this context because of its lower occurrence of adverse respiratory events.

RESUMEN

BACKGROUND: Malnutrition poses a substantial challenge in Somalia, impacting approximately 1.8 million children. This critical issue is exacerbated by a multifaceted interplay of factors. Consequently, this study seeks to examine the long-term and short-term effects of armed conflicts, food price inflation, and climate variability on global acute malnutrition in Somalia. METHODS: The study utilized secondary data spanning from January 2015 to December 2022, sourced from relevant databases. Two distinct analytical approaches were employed to comprehensively investigate the dynamics of global acute malnutrition in Somalia. Firstly, dynamic autoregressive distributed lag (ARDL) simulations were applied, allowing for a nuanced understanding of the short and long-term effects of armed conflicts, food price inflation, and climate variability on malnutrition. Additionally, the study employed kernel-based regularized least squares, a sophisticated statistical technique, to further enhance the robustness of the findings. The analysis was conducted using STATA version 17. RESULTS: In the short run, armed conflicts and food price inflation exhibit positive associations with global acute malnutrition, particularly in conflict-prone areas and during inflationary periods. Moreover, climatic variables, specifically temperature and rainfall, demonstrate positive associations. It is important to note that temperature lacks a statistically significant relationship with global acute malnutrition in the short run. In the long run, armed conflicts and food price inflation maintain persistent impacts on global acute malnutrition, as confirmed by the dynamic ARDL simulations model. Furthermore, both temperature and rainfall continue to show positive associations with global acute malnutrition, but it is worth noting that temperature still exhibits a non-significant relationship. The results from kernel-based regularized least squares were consistent, further enhancing the robustness of the findings. CONCLUSIONS: Increased armed conflicts, food price inflation, temperature, and rainfall were associated with increased global acute malnutrition. Strategies such as stabilizing conflict-prone regions, diplomatic interventions, and peace-building initiatives are crucial, along with measures to control food price inflation. Implementing climate adaptation strategies is vital to counter temperature changes and fluctuating rainfall patterns, emphasizing the need for resilience-building. Policymakers and humanitarian organizations can leverage these insights to design targeted interventions, focusing on conflict resolution, food security, and climate resilience to enhance Somalia's overall nutritional well-being.

RESUMEN

Background: Letrozole, an aromatase inhibitor, has recently been introduced as the preferred treatment option for ectopic pregnancy. To date, no study has investigated the effect of letrozole alone on placental tissue. The present study aimed to evaluate the effect of different doses of letrozole on the placenta of rats and to clarify the underlying mechanism. Methods: Sixty pregnant female rats were equally divided into three groups, namely the control group (GI), low-dose (0.5 mg/Kg/day) letrozole group (GII), which is equivalent to the human daily dose (HED) of 5 mg, and high-dose (1 mg/Kg/day) letrozole group (GIII), equivalent to the HED of 10 mg. Letrozole was administered by oral gavage daily from day 6 to 16 of gestation. Data were analyzed using a one-way analysis of variance followed by Tukey's post hoc test and Chi square test. P<0.05 was considered statistically significant. Results: Compared to the GI and GII groups, high-dose letrozole significantly increased embryonic mortality with a high post-implantation loss rate (P<0.001) and significantly reduced the number of viable fetuses (P<0.001) and placental weight (P<0.001) of pregnant rats. Moreover, it significantly reduced placental estrogen receptor (ER) and progesterone receptor (PR) (P<0.001) and the expression of vascular endothelial growth factor (P<0.001), while increasing the apoptotic index of cleaved caspase-3 (P<0.001). Conclusion: Letrozole inhibited the expression of ER and PR in rat placenta. It interrupted stimulatory vascular signals causing significant apoptosis and placental vascular dysfunction. Letrozole in an equivalent human daily dose of 10 mg caused a high post-implantation loss rate without imposing severe side effects.

RESUMEN

Introduction: in developing countries, diarrhea is a major cause of child death among those under five years old. Dehydration, malnutrition, delayed physical development and early childhood mortality are the major consequences of diarrheal diseases. In Somaliland, diarrheal diseases have been endemic and a major problem since 1994, with epidemics occurring annually. This study aimed to assess the prevalence and risk factors of acute diarrhea among children under five years old living in Hargeisa Internally Displaced Persons (IDPs), Somaliland. Methods: a community-based cross-sectional study was conducted among mothers of children under five from August to September 2020 in Hargeisa IDPs. A total of 383 mothers were selected using single population proportional formula. Data was entered, cleaned, and analyzed using SPSS version 22. To explore the association between variables, bivariate logistic regression was performed for each independent variable with the dependent variable. Variables with a p-value of < 0.05 were adjusted in multivariate logistic regression. Finally, variables with a p-value < 0.05 were recognized as determinants of acute diarrheal disease. Results: the prevalence of diarrhea among children under five living in Hargeisa IDPs was 51% (95% CI: 46%-56%). Children older than one year (AOR= 3.59, 95% CI: 2.05-5.20), those not exclusively breastfed (AOR= 4.01, 95% CI: 3.27-4.60), those not given colostrum milk (AOR= 36.41, 95% CI: 25.76-47.90), those drinking water stored in jerry-cans (AOR = 4.90, 95% CI: 1.31-8.39), and those with poor hand washing practices (AOR = 5.74, 95% CI: 1.38-7.82) were more likely to develop diarrhea than their counterparts. Conclusion: this study concludes that the prevalence of diarrhea was very high (51%). Lack of awareness of exclusive breastfeeding and colostrum feeding, storing drinking water in unprotected containers, and poor hand-washing practices were identified as significant predictors for childhood diarrhea (p-value < 0.05).

RESUMEN

OBJECTIVE: To investigate the anogenital distance from the upper verge of the anus to the posterior fourchette (AGDAF ), FASL, and BCL2 combination as a reliable and non-invasive tool for the diagnosis of endometriosis. METHODS: This study included 100 women with endometriosis and 50 women without endometriosis as the control group. All cases underwent history taking, body mass index (BMI) measurement, AGD measurement, and FASL and BCL2 immunohistochemical staining of the eutopic endometrial tissue. RESULTS: This study included 150 women divided into endometriosis and control groups. Endometriosis cases significantly had shorter AGDAF , 22.9 ± 2.6 mm, compared with the control group, 27.3 ± 3.5 mm (P < 0.001). Lower FASL and higher BCL2 expression were associated with endometriosis (P < 0.001). The combined measurement of AGDAF (cut-off point 24.55 mm) with FASL and BCL2 was associated with endometriosis (P < 0.001). The combined diagnostic sensitivity, specificity, positive predictive value, and negative predictive value of AGDAF , FASL, and BCL2 were 83%, 78%, 87.3%, and 69.6%, respectively. The area under the curve was greater for AGDAF , FASL, and BCL2 in combination than for individual measurements. CONCLUSION: Combining short AGDAF with high BCL2 and low FASL is a highly sensitive, non-invasive diagnostic tool for endometriosis.

RESUMEN

Background: Stunting, a consequence of prolonged malnutrition, remains a critical global health issue affecting 165 million children under the age of five, with 10.6 million associated deaths. Its stunting prevalence is particularly pronounced in developing nations, notably Sub-Saharan Africa. Chronic protein-energy malnutrition, identified as a major cause of morbidity and mortality in displaced settings, underscores the urgency of understanding its impact in such contexts. Objective: This study aimed to assess the prevalence and associated factors of stunting among children aged 12-59 months and residing in IDP camps in Hargeisa, Somaliland. Methods: A community-based cross-sectional study was conducted in Hargeisa from May 5 to July 30, 2022, utilizing systematic random sampling, online mobile surveys, and caregiver interviews with anthropometric measurements. The SPSS version 25 was utilized in handled data entry, processing and analysis. Multivariable logistic regression, with p < 0.05 significance, included variables from bivariate analysis (p < 0.2). Stunting assessment utilized WHO AnthroPlus software, categorizing HAZ scores < -2.0 SD. Results: The prevalence of stunting among children living in IDP camps was found to be 21.1% [95% CI: 17.0-24.91%]. Vaccination status (adjusted odds ratio [aOR] = 0.19, 95% CI: 0.09-0.38), deworming practice (aOR = 6.5, 95% CI: 2.91-14.52), place of delivery (aOR = 0.14, 95% CI: 0.07-0.30), measles experience in the last year (aOR = 0.12, 95% CI: 0.04-0.34), ANC visits (aOR = 0.33, 95% CI: 0.14-0.81), and maternal insufficient extra food intake (aOR = 2.15, 95% CI: 1.11-4.15) were significantly associated with stunting. Conclusion: The observed stunting prevalence in IDP camps (21.1%) was substantial, highlighting the need for targeted interventions. Future efforts should aim to reduce stunting from the current rate to an estimated 5-10%, emphasizing comprehensive measures such as deworming, maternal nutrition, postnatal care improvement, robust immunization, and promoting healthcare facility deliveries.

RESUMEN

INTRODUCTION: Kenya faces significant challenges related to health worker shortages, low retention rates, and the equitable distribution of Human Resource for Health (HRH). The Ministry of Health (MOH) in Kenya has established HRH norms and standards that define the minimum requirements for healthcare providers and infrastructure at various levels of the health system. The study assessed on the progress of Universal Health Coverage (UHC) piloting on Human Resource for Health in the country. METHODS: The study utilized a Convergent-Parallel-Mixed-Methods design, incorporating both quantitative and qualitative approaches. The study sampled diverse population groups and randomly selected health facilities. Four UHC pilot counties are paired with two non-UHC pilot counties, one neighboring county and the second county with a geographically distant and does not share a border with any UHC pilot counties. Stratification based on ownership and level was performed, and the required number of facilities per stratum was determined using the square root allocation method. Data on the availability of human resources for health was collected using a customized Kenya Service Availability and Readiness Assessment Mapping (SARAM) tool facilitated by KoBo ToolKitTM open-source software. Data quality checks and validation were conducted, and the HRH general service availability index was measured on availability of Nurses, Clinician, Nutritionist, Laboratory technologist and Pharmacist which is a minimum requirement across all levels of health facilities. Statistical analyses were performed using IBM SPSS version 27 and comparisons between UHC pilot counties and non-UHC counties where significance threshold was established at p < 0.05. Qualitative data collected using focus group discussions and in-depth interview guides. Ethical approval and research permits were obtained, and written informed consent was obtained from all participants. RESULTS: The study assessed 746 health facilities with a response rate of 94.3%. Public health facilities accounted for 75% of the sample. The overall healthcare professional availability index score was 17.2%. There was no significant difference in health workers' availability between UHC pilot counties and non-UHC pilot counties at P = 0.834. Public health facilities had a lower index score of 14.7% compared to non-public facilities at 27.0%. Rural areas had the highest staffing shortages, with only 11.1% meeting staffing norms, compared to 31.8% in urban areas and 30.4% in peri-urban areas. Availability of health workers increased with the advancement of The Kenya Essential Package for Health (KEPH Level), with all Level 2 facilities across counties failing to meet MOH staffing norms (0.0%) except Taita Taveta at 8.3%. Among specific cadres, nursing had the highest availability index at 93.2%, followed by clinical officers at 52.3% and laboratory professionals at 55.2%. The least available professions were nutritionists at 21.6% and pharmacist personnel at 33.0%. This result is corroborated by qualitative verbatim. CONCLUSION: The study findings highlight crucial challenges in healthcare professional availability and distribution in Kenya. The UHC pilot program has not effectively enhanced healthcare facilities to meet the standards for staffing, calling for additional interventions. Rural areas face a pronounced shortage of healthcare workers, necessitating efforts to attract and retain professionals in these regions. Public facilities have lower availability compared to private facilities, raising concerns about accessibility and quality of care provided. Primary healthcare facilities have lower availability than secondary facilities, emphasizing the need to address shortages at the community level. Disparities in the availability of different healthcare cadres must be addressed to meet diverse healthcare needs. Overall, comprehensive interventions are urgently needed to improve access to quality healthcare services and address workforce challenges.

RESUMEN

Assisted reproduction is a risk factor for adnexal torsion due to ovarian hyperstimulation and increased incidence of twin pregnancy. Both risk factors can be eliminated in frozen embryo transfers, but in our case ovarian torsion occurred after the use of an aromatase inhibitor (Femara) in endometrium preparation due to the presence of corpus luteum. Case presentation: G2P1+0 presented at 7 weeks gestation after vitrified-warmed embryo transfer with right loin pain and mild right iliac pain and tenderness. Ultrasound examination revealed transient or incomplete ovarian torsion. The presentation of the case was somewhat misleading and the transient nature of the torsion provided an opportunity for the conservative management of the case. In conclusion, ovarian torsion is still an undesired event, even after single embryo transfers and in vitrified-warmed cycles. Clinical and ultrasound follow-up precluded the need for surgery in our case.

RESUMEN

OBJECTIVE: The present study aims to compare prophylactic common iliac artery (CIA) temporary clamping and preoperative balloon occlusion for managing placenta accreta spectrum (PAS) disorders. STUDY DESIGN: Between January 2019 and June 2020, 46 patients with PAS disorders were included. Of them, 26 patients were offered CIA balloon occlusion (Group A), while temporary CIA clamping was done for the other 20 patients (Group B). Primary outcomes were procedure-related complications, and secondary outcomes included intraoperative and postoperative complications, reoperation rates, total procedure time, blood loss, and amount of blood transfusion. RESULTS: Blood loss was statistically non-significant higher in group B than in group A (p-value = 0.143). Only one patient in group A and three in group B needed reoperation. The bleeding continued for a mean of 1.6 days in group A and 1.7 days in group B, with non-significant statistical differences between both groups p value = 0.71. Nine patients in group A (34.6%) and four in group B (20%) required ICU admission. The mean Apgar score was 7 and 6.6 in babies of group A and group B patients, respectively. The median number of allogeneic blood transfusions performed was two in patients in group A and 1 in group B (p-value = 0.001). CONCLUSION: Both techniques offer good choices for patients with PAS to decrease mortality and morbidity rates. The selection of a better technique depends on institutional references and physicians' experience.

RESUMEN

BACKGROUND: Many monolithic machined materials have been introduced and provided a suitable mechanical and physical properties for inlay restorations. However, there is shortage in the studies evaluating the marginal adaptation using these materials. PURPOSE: This study aimed to compare the effect of fabricating inlay restorations from 3 different CAD-CAM materials on marginal gaps before and after thermocycling. MATERIALS AND METHODS: Sixty human premolars were randomly divided into 3 groups (n = 20) according to the material used: (e.max CAD, Ivoclar AG, Schaan, Liechtenstein), (HC, Shofu, Koyoto, Japan) and (Brilliant Crios, Coltene, Altstätten, Switzerland) (n = 20). A scanning electron microscope (SEM) (JSM- 6510 lv, JEOL, Tokyo, JAPAN) was used to for measuring the marginal gaps after cementation of inlay restorations. The magnification was adapted to 250x. Marginal gaps were revaluated with SEM after thermocycling. The temperatures of baths were 5 and 55 °C was applied for a total of 5000 cycles. All data were statistically analyzed by using ANCOVA to demonstrate if there were any statistically significant differences between the gap measures after thermocycling of the three independent (unrelated) groups. A Bonferroni adjustmen was used to perform post hoc analysis (α = 0.05). RESULTS: Post-intervention marginal gap was statistically significantly lower in group EX (110.8 µm) which was statistically significant compared with group SF (112.5 µm) (mean difference=-1.768, P = .007) and group BR (113 µm) (mean difference=-2.272, P = .001), however, in. comparing SF and BR groups, there was no significant difference (mean difference=-0.5, P = .770). CONCLUSIONS: Thermocycling affected the marginal gaps of composite based restoration and resin-modified ceramics widely. However, it had a very small effect on glass ceramics marginal adaptation. CLINICAL IMPLICATIONS: The marginal gaps of CAD-CAM inlays varied according to material used (ceramic based, combination, or resin based). Thermocycling has a minor effect on the marginal adaptation of lithium disilicate glass-ceramic inlays, where it affected the margin of resin-modified ceramic and composite based inlays greatly. Using lithium disilicate glass-ceramic might improve the clinical longevity of inlay restored teeth.

RESUMEN

Hepatitis A virus (HAV) and Hepatitis E virus (HEV) are transmitted through the fecal-oral route. HAV outbreaks and one HEV outbreak have been reported in Egypt. However, the impact of HAV-HEV co-infection is not known. In this study, we assessed HEV markers in acute HAV-infected patients (n = 57) enrolled in Assiut University hospitals. We found that 36.8% of HAV-infected patients were also positive for HEV markers (anti-HEV IgM and HEV RNA), while 63.2% of the patients were HAV mono-infected. Demographic and clinical criteria were comparable in both HAV mono-infected patients and HAV-HEV co-infected patients. Although liver enzymes were not significantly different between the two groups, liver transaminases were higher in the co-infected patients. Six patients developed acute liver failure (ALF); five of them were HAV-HEV-co-infected patients. The relative risk of ALF development was 8.5 times higher in HAV-HEV co-infection compared to mono-infection. Three cases of ALF caused by HAV-HEV co-infection were reported in children (below 18 years) and two cases were reported in adults. All patients developed jaundice, coagulopathy, and encephalopathy; all were living in rural communities. In conclusion: HAV-HEV co-infection can be complicated by ALF. The risk of ALF development in HAV-infected patients is higher when coinfection with HEV is present.

RESUMEN

Partial shading of solar panels diminishes their operating efficiency and energy synthesized as it disrupts the uniform absorption of sunlight. To tackle the issue of partial shading in photovoltaic (PV) systems, this article puts forward a comprehensive control strategy that takes into account a range of contributing factors. The proposed control approach is based on using multi-string PV system configuration in place of a central-type PV inverter for all PV modules with a single DC-DC converter. This adaptation enhances overall efficiency across varying radiation levels. Also, the proposed technique minimizes the overall system cost by reducing the required sensors number by utilizing a radiation estimation strategy. The converter switching strategy is synthesized considering direct duty-cycle control method to establish the maximum power point (MPP) location on the P-V curve. The direct duty-cycle tracking approach simplifies the control system and improves the system's response during sudden partial shading restrictions. To validate the effectiveness of the suggested MPPT method, two system configurations were constructed using MATLAB/SIMULINK software and assessed under various partial shading scenarios. Additionally, a multi-string system was subjected to real irradiance conditions. The sensor-less MPPT algorithm proposed achieved an impressive system efficiency of 99.81% with a peak-to-peak ripple voltage of 1.3V. This solution offers clear advantages over alternative approaches by reducing tracking time and enhancing system efficiency. The system findings undoubtedly support the theoretical scrutiny of the intended technique.

RESUMEN

A "building block" is a key component that plays a substantial and critical function in the pharmaceutical research and development industry. Given its structural versatility and ability to undergo substitutions at both the amino and carboxyl groups, para-aminobenzoic acid (PABA) is a commonly used building block in pharmaceuticals. Therefore, it is great for the development of a wide range of novel molecules with potential medical applications. Anticancer, anti-Alzheimer's, antibacterial, antiviral, antioxidant, and anti-inflammatory properties have been observed in PABA compounds, suggesting their potential as therapeutic agents in future clinical trials. PABA-based therapeutic chemicals as molecular targets and their usage in biological processes are the primary focus of this review study. PABA's unique features make it a strong candidate for inclusion in a massive chemical database of molecules having drug-like effects. Based on the current literature, further investigation is needed to evaluate the safety and efficacy of PABA derivatives in clinical investigations and better understand the specific mechanism of action revealed by these compounds.

RESUMEN

BACKGROUND: Routine immunization contributes greatly to reduction in mortality from vaccine preventable diseases among children. The Somaliland Demographic and Health survey, 2020 revealed that only 13.7% of children in Marodijeh (Hargeisa) region had received all recommended vaccines, which is far below the World Health Organization (WHO) target of 80%. We therefore, assessed factors associated with immunization coverage among children under five years at Mohamed Mooge Health Center in Hargeisa, Somaliland. METHODS: Institutional based cross-sectional study was conducted on 174 systematically sampled, consented mothers that visited Mohamed Mooge Health Center for antenatal care during December 2022 to May 2023. Data was collected using a structured questionnaire. Data was analysed using SPSS and the relationship between dependent and independent variables was checked chi-square test at p ≤ 0.05. Finally, candidate variables were tested by using multivariate logistic regression in order to control potential confounders and the result was presented using AOR and 95% confidence interval. Model fitness was checked using Hosmer-Lemeshaw goodness of fit test with P > 0.05 for fitness. Multicollinearity between variables was checked using correlation coefficients at 0.80 or higher.  RESULT: Among 174 study participants, the prevalence of overall vaccine completion in this study was 55.3%. Women who had being aware about childhood immunization on BCG vaccination (AOR = 3.887; 95% CI: 1.275, 6.844), pentavalent (AOR = 11.385; 95% CI: 5.424-14.464), and measles (AOR = 3.074; 95% CI: 1.822-6.130) had higher odds of having immunized their children. Mothers who had employment had higher odds of having their children immunized against measles (AOR = 4.069; 95% CI: 1.822-6.130) compared to those who had not. CONCLUSIONS: Full immunization coverage was lower than the target set by the World Health Organization in this study area. The current study revealed that, the mother's awareness of childhood vaccinations on BCG, pentavalent, measles and employment status of mothers were positively associated with immunization coverage. To promote vaccination coverage, the government should implement a national awareness campaign on childhood immunization and increase the number of outreach services.

RESUMEN

Diabetes is a major cause of morbidity and mortality worldwide yet preventable. Complications of undetected and untreated diabetes result in serious human suffering and disability. It negatively impacts on individual's social economic status threatening economic prosperity. There is a scarcity of data on health system diabetes service readiness and availability in Kenya which necessitated an investigation into the specific availability and readiness of diabetes services. A cross sectional descriptive study was carried out using the Kenya service availability and readiness mapping tool in 598 randomly selected public health facilities in 12 purposively selected counties. Ethical standards outlined in the 1964 Declaration of Helsinki and its later amendments were upheld throughout the study. Health facilities were classified into primary and secondary level facilities prior to statistical analysis using IBM SPSS version 25. Exploratory data analysis techniques were employed to uncover the distribution structure of continuous study variables. For categorical variables, descriptive statistics in terms of proportions, frequency distributions and percentages were used. Of the 598 facilities visited, 83.3% were classified as primary while 16.6% as secondary. A variation in specific diabetes service availability and readiness was depicted in the 12 counties and between primary and secondary level facilities. Human resource for health reported a low mean availability (46%; 95% CI 44%-48%) with any NCDs specialist and nutritionist the least carder available. Basic equipment and diagnostic capacity reported a fairly high mean readiness (73%; 95% CI 71%-75%) and (64%; 95%CI 60%-68%) respectively. Generally, primary health facilities had low diabetic specific service availability and readiness compared to secondary facilities: capacity to cope with diabetes increased as the level of care ascended to higher levels. Significant gaps were identified in overall availability and readiness in both primary and secondary levels facilities particularly in terms of human resource for health specifically nutrition and laboratory profession.

RESUMEN

BACKGROUND AND OBJECTIVES: Prognosticators of good functional outcome after minimally invasive surgical (MIS) intracranial hemorrhage (ICH) evacuation are poorly defined. This study aims to investigate clinical and radiographic prognosticators of poor functional outcome after MIS evacuation of ICH with tubular retractor systems. METHODS: Single-center retrospective review of adult (age ≥18 years) patients who underwent surgical evacuation of a spontaneous supratentorial ICH evacuation using tubular retractors from 2013 to 2022 was performed. Clinical and radiographic factors, such as antiplatelet/anticoagulant use, initial NIH Stroke Scale, ICH score, premorbid modified Rankin Scale (mRS), intraventricular hemorrhage (IVH) severity according to the modified Graeb scale, and preoperative/postoperative ICH volume, were collected. The main outcome was poor functional outcome, defined as mRS score of 4-6 within 1 year postoperatively. RESULTS: Eighty-eight patients were included. Clinical follow-up data were available for 64 (73%) patients. Of those, 43 (67%) had a poor functional outcome. On multivariate Cox regression, postoperative ICH volume ≥15 mL (hazard ratio [HR] = 2.46 [95% CI: 1.25-4.87]; P = .010) and higher modified Graeb score (HR = 1.04 [95% CI: 1-1.1]; P = .035] significantly increased the risk of poor functional outcome. Elevated postoperative ICH volume was predicted by the presence of lobar ICH (vs nonlobar, OR = 3.32 [95% CI: 1.01-11.55]; P = .043) and higher preoperative ICH volume (OR = 1.05 [1.02-1.08]; P < .001). A minimum of 60% ICH evacuation yielded an improvement in mRS 4-6 rates (HR 0.3 [95% CI: 0.1-0.8], P = .013). In patients without IVH and with a >80% ICH evacuation, the rate of mRS 4-6 was 42% compared with 67% in the whole patient sample ( P = .017). CONCLUSION: Increased IVH volumes and residual postoperative ICH volumes are associated with poor functional outcome after MIS ICH evacuation. Postoperative ICH volume was associated with lobar ICH location as well as preoperative ICH volume. These factors may help to prognosticate patient outcomes and improve selection criteria for MIS ICH evacuation techniques.
