Effect of COVID-19 pandemic on provision of sexual and reproductive health services in primary health facilities in Nigeria: a cross-sectional study.

BACKGROUND: Nigeria, like many other countries, has been severely affected by the COVID-19 pandemic. While efforts have been devoted to curtailing the disease, a major concern has been its potential effects on the delivery and utilization of reproductive health care services in the country. The objective of the study was to investigate the extent to which the COVID-19 pandemic and related lockdowns had affected the provision of essential reproductive, maternal, child, and adolescent health (RMCAH) services in primary health care facilities across the Nigerian States. METHODS: This was a cross-sectional study of 307 primary health centres (PHCs) in 30 Local Government Areas in 10 States, representing the six geopolitical regions of the country. A semi-structured interviewer-administered questionnaire was used to obtain data on issues relating to access and provision of RMCAH services before, during and after COVID-19 lockdowns from the head nurses/midwives in the facilities. The questionnaire was entered into Open Data Kit mounted on smartphones. Data were analysed using frequency and percentage, summary statistics, and Kruskal-Wallis test. RESULTS: Between 76 and 97% of the PHCS offered RMCAH services before the lockdown. Except in antenatal, delivery and adolescent care, there was a decline of between 2 and 6% in all the services during the lockdown and up to 10% decline after the lockdown with variation across and within States. During the lockdown. Full-service delivery was reported by 75.2% whereas 24.8% delivered partial services. There was a significant reduction in clients' utilization of the services during the lockdown, and the difference between States before the pandemic, during, and after the lockdown. Reported difficulties during the lockdown included stock-out of drugs (25.7%), stock-out of contraceptives (25.1%), harassment by the law enforcement agents (76.9%), and transportation difficulties (55.8%). Only 2% of the PHCs reported the availability of gowns, 18% had gloves, 90.1% had hand sanitizers, and a temperature checker was available in 94.1%. Slightly above 10% identified clients with symptoms of COVID-19. CONCLUSIONS: The large proportion of PHCs who provided RMCAH services despite the lockdown demonstrates resilience. Considering the several difficulties reported, and the limited provision of primary protective equipment more effort by the government and non-governmental agencies is recommended to strengthen delivery of sexual and reproductive health in primary health centres in Nigeria during the pandemic.

The onset of COVID-19 has raised concerns that it may compromise women's access to sexual and reproductive health and rights. Although data are still emerging, some reports indicate reduced access to sexual and reproductive health services, largely due to disruptions in the demand and supply of contraceptive commodities, the diversion of staff and resources to other clinical services, and clinic closures. While these concerns have similarly been broached for Nigeria, there has been no systematic documentation of the extent of the disruptions of reproductive health services caused by COVID-19 and its effects on the provision and utilization of related services in the country This study was a cross-sectional facility-based survey conducted in 10 states, 30 Local Government Areas and 302 primary health centres in Nigeria. The objective of the study was to explore through key informant interviews with service providers in the health centres, the effects of the COVID-19 pandemic on demand and supply of sexual and reproductive health services. Field assistants administered a semi-structured interview guide to the heads of the health centres that elicited information on availability and use of the health centres before, during and after the lock-downs associated with the pandemic. The results indicate that a large proportion of the health centres opened for the provision of essential sexual and reproductive health services during the COVID-19 pandemic lockdown. However, fewer clients used the services due to difficulties in travel because of the lockdowns, stock-outs in the health centres, and the fear that they may contract the virus if they leave their houses to the health centres. Although the health centres reported some cases of COVID-19, there was limited provision for personal protective equipment to motivate the health workers to optimize services for clients. From this study, we conclude that efforts should be made to identify innovations for addressing these challenges to enable the continued provision of sexual and reproductive health services by health centres despite the COVID-19 pandemic in Nigeria's health centres.

Pathobiology of ischiocavernosus and bulbospongiosus muscles in long-term diabetic male rats and its implication on erectile dysfunction.

OBJECTIVE: To analyze pathobiology of ischiocavernosus (IC) and bulbospongiosus (BS) muscles in long-term diabetic male rats and its implication on erectile dysfunction (ED). METHODS: Male rats were grouped into control and diabetic rats (received single injection of 60 mg/kg bw. of streptozotocin [STZ]). At 120th day, the animals were subjected to various analyses like serum hormone, penile reflex, electromyography of IC and BS muscles, after euthanasia IC and BS muscles were processed for morphological, histology, histometric analysis, immunostaining and immunoblotting synaptophysin, nNOS and NADPH diaphorase histochemistry. RESULTS: Significant reduction in serum hormone level, penile reflex, reduced action potential or activity in both these muscles and wide range of histological alterations were observed in STZ rats. Muscles showed significant reduction in the diameter, volume and numerical density of the fiber in both muscles of STZ rats. Synaptophysin, nNOS and NADPH diaphorase were significantly reduced in diabetic animal IC and BS. CONCLUSION: Severe neuromuscular circuitry alteration in IC and BS. Study concludes that degenerative changes in IC and BS may play a major role in ED in diabetic condition. Indicating diabetic-induced postsynaptic neuronal degeneration along with impaired motor action of the muscle and severe muscle degeneration affecting ED.

Therapeutic potential of Mucuna pruriens (Linn.) on ageing induced damage in dorsal nerve of the penis and its implication on erectile function: an experimental study using albino rats.

OBJECTIVE: To study the effect of ethanolic seed extract of Mucuna pruriens on damaged dorsal nerve of the penis (DNP) in aged rat in relation to penile erection. METHODS: The rats were divided into four groups Young (3 months), Aged (24 - 28 months), Aged + M. pruriens, and Young + M. pruriens (200 mg/kg b.w/60 days) and were subjected to the hypophysial - gonadal axis, nerve conduction velocity (NCV), and penile reflex. DNP sections were stained with nitric oxide synthase (nNOS), nicotinamide adenine dinucleotide phosphate (NaDPH) diaphorase, androgen receptor (AR), and osmium tetroxide. Terminal deoxynucleotidyl transferase (TdT) dUTP Nick-End Labeling (TUNEL) staining, electron microscopy(EM) and histometric analyses were done. RESULTS: Significant disturbance in hypophysial - gonadal axis was noted in aged rat. With reduced number of myelinated fibers, diameter, vacuolization, indentation of the myelin sheath, and degeneration. nNOS and its cofactor (NaDPH diaphorase) were reduced in aged rat DNP. NCV was slow in aged rats and concomitant poor penile reflex was also noted. AR showed reduced expression in aged rat DNP when compared to young and control groups. TUNEL positive cells were increased in aged rat DNP. These pathological changes were remarkably reduced or recovered in M. pruriens treated aged rats. CONCLUSIONS: The results indicate a multi-factorial therapeutic activity in penile innervations towards sustaining the penile erection in the presence of the extract in aged rats and justifying the claim of traditional usage.

Ameliorative Effect of Epigallocatechin Gallate on Cardiac Hypertrophy and Fibrosis in Aged Rats.

The objective of the present study is to evaluate the effect of epigallocatechin gallate (EGCG) on aging-mediated cardiac hypertrophy, fibrosis, and apoptosis. The Wistar albino rats were divided into 4 groups (n = 18). Group I: young (3 months), group II: aged (24-26 months), group III: aged + EGCG (200 mg/kg for 30 days), and group IV: young + EGCG. At the end of 30 days, EGCG administration to the aged animals showed significant (P < 0.001) reduction of low-density lipoprotein, very low-density lipoprotein, triglyceride, total cholesterol with concomitant increase of high-density lipoprotein (P < 0.001) when compared with aged rats. Increased (P < 0.001) heart volume, weight with concomitant increase of left ventricular wall thickness, and reduced ventricular cavity were observed in aged rats supplemented with EGCG compared with aged animals. Histology and histomorphometry study of aged animals treated with EGCG showed marked increases in the diameter and volume of cardiomyocytes with concomitant reduction of numerical density when compared with aged animals. Reduced reactive oxygen species (P < 0.001) production with association of increased antioxidant defense system (P < 0.001) in aged hearts supplemented with EGCG when compared with aged animals. TUNEL staining and fibrosis showed a marked increase in apoptotic cell death (P < 0.001) and collagen deposition (P < 0.001) in aged animals treated with EGCG when compared with aged animals. Aged animals treated with EGCG showed a marked increase in protein expression of TGFß, TNFα, and nuclear factor kappa B (NF-κB) and significant (P < 0.001) alteration in the gene expression of TGFß, TNFα, NF-κB, α-SMA, and Nrf2 when compared with aged animals. Taken together, it is evident that EGCG may potentially inhibit aging-induced cardiac hypertrophy, fibrosis, and apoptosis, thereby preserving cardiac function. The proposed mechanism would be inhibition of reactive oxygen species-dependent activation of TGFß1, TNFα, and NF-κB signaling pathway. Hence, the present study suggests that EGCG can be useful to fight against aging-induced cardiac hypertrophy, fibrosis, and apoptosis.

Fish Oil Derivatives in Hypertriglyceridemia: Mechanism and Cardiovascular Prevention: What Do Studies Say?

Hypertriglyceridemia is a type of dyslipidemia characterized by high triglyceride levels in the blood and increases the risk of cardiovascular disease. Conventional management includes antilipidemic medications such as statins, lowering LDL and triglyceride levels as well as raising HDL levels. However, the treatment may be stratified using omega-3 fatty acid supplements such as eicosatetraenoic acid (EPA) and docosahexaenoic acid (DHA), aka fish oil derivatives. Studies have shown that fish oil supplements reduce the risk of cardiovascular diseases; however, the underlying mechanism and the extent of reduction in CVD need more clarification. Our paper aims to review the clinical trials and observational studies in the current literature, investigating the use of fish oil and its benefits on the cardiovascular system as well as the proposed underlying mechanism.

Comparative safety review of antithrombotic treatment options for patients with atrial fibrillation undergoing percutaneous coronary intervention.

INTRODUCTION: Balancing antithrombotic therapy for atrial fibrillation (AF) patients undergoing percutaneous coronary intervention (PCI) remains a clinical challenge due to coexisting thrombogenic risks. This review emphasizes the delicate balance required to prevent ischemic events while minimizing bleeding complications, particularly in the context of risk assessment. AREAS COVERED: This review spans from 2010 to October 2023, exploring the complexities of antithrombotic management for AF patients undergoing PCI. It stresses the need for personalized treatment decisions to optimize antithrombotic therapies effectively. EXPERT OPINION: The evolving evidence supports double antithrombotic therapy (DAT) over triple antithrombotic therapy (TAT) for these patients, showcasing a more favorable safety profile without compromising efficacy. Non-vitamin K antagonist oral anticoagulant (NOAC)-based DAT strategies exhibit superiority in reducing major bleeding events while effectively preventing ischemic events. Recommendations from the 2023 European Society of Cardiology (ESC) Guidelines advocate for NOAC-based DAT post-PCI, endorsing safer antithrombotic profiles.Challenges persist for specific patient categories requiring both oral anticoagulants and antiplatelets, necessitating personalized approaches. Future advances in intravascular imaging and novel coronary stent technologies offer promising avenues to optimize outcomes and influence antithrombotic strategies in AF-PCI patients.

The impact of air quality on cardiovascular health: A state of the art review.

Air pollution is a global health challenge, increasing the risk of cardiovascular diseases such as heart disease, stroke, and arrhythmias. Particulate matter (PM), particularly PM2.5 and ultrafine particles (UFP), is a key contributor to the adverse effects of air pollution on cardiovascular health. PM exposure can lead to oxidative stress, inflammation, atherosclerosis, vascular dysfunction, cardiac arrhythmias, and myocardial injury. Reactive oxygen species (ROS) play a key role in mediating these effects. PM exposure can also lead to hypertension, a significant risk factor for cardiovascular disease. The COVID-19 pandemic resulted in a significant reduction of air pollutants, leading to a decline in the incidence of heart attacks and premature deaths caused by cardiovascular diseases. This review highlights the relationship between environmental air quality and cardiovascular health, elucidating the pathways through which air pollutants affect the cardiovascular system. It also emphasizes the need for increased awareness, collective efforts to mitigate the adverse effects of air pollution, and strategic policies for long-term air quality improvement to prevent the devastating effects of air pollution on global cardiovascular health.

A spatial regression approach to modeling urban land surface temperature.

Land surface temperature (LST) is the instantaneous radiative skin temperature of land obtained from satellite sensors. Measured by visible, infrared or microwave sensors, the LST is useful in determining thermal comfort for urban planning. It also serves as a precursor to many underlying impacts such as health, climate change and the likelihood of rainfall. Due to the paucity of observed data because of cloud cover or rain-bearing clouds in the case of microwave sensors, it is necessary to model LST for the purpose of forecasting. Two spatial regression models were employed: the spatial lag model and the spatial error model. Using Landsat 8 and Shuttle Radar Topography Mission (SRTM), these models can be studied and compared in terms of their robustness in reproducing LST. Whereas LST is to be the independent variable, built-up area, water surface, albedo, elevation, and vegetation are to be considered as dependent variables and their relative contributions to LST examined.•Modeling LST based on spatial regression models with calculated LST as independent variable.•Dependent variables to be considered are normalised difference Built-up index (NDBI), normalised difference vegetation index (NDVI), modified normalised difference water index (MNDWI), albedo and elevation.•The models were validated using k-fold cross validation method, mean square error and standard deviation.

Properties of galactomannans and their textile-related applications-A concise review.

Galactomannans are reserve carbohydrates in legume plants and are primarily extracted from their seeds. They contain galactose side chains throughout the mannose backbone and have unique features such as emulsifying, thickening, and gelling together with biodegradability, biocompatibility, and non-toxicity, which make them an appealing material. Guar gum and locust bean gum mainly are used in all galactomannan needed applications. Nonetheless, tara gum and fenugreek gum have also attracted considerable attention in recent decades. Despite the increased usage of galactomannans in the textile-related fields in recent years, there is no review article published yet. To fill this gap and to demonstrate the striking and increasing importance of galactomannans, a concise summary of the properties of common galactomannans and their comparisons is given first, followed by an account of recent developments and applications of galactomannans in the textile-related fields. The associated potential opportunities are also provided at the end of this review.

Benefit and risk evaluation of quinapril hydrochloride.

INTRODUCTION: Angiotensin-converting enzyme (ACE) inhibitors are a mainstay of antihypertensive therapy. Quinapril hydrochloride, a less commonly used, and less-studied ACE inhibitor has been approved for its primary use in hypertension. Studies also indicate its off-label use for congestive heart failure and diabetic nephropathy. The ANDI and TREND trials have been pivotal in demonstrating the effectiveness of quinapril. AREAS COVERED: The authors conducted a review of the literature analyzing the clinical efficacy and safety profile of quinapril. This review discusses the development of quinapril, provides an updated summary of the indications and contraindications, and presents a comparison with other ACE inhibitors. EXPERT OPINION: Quinapril is a safe and well-tolerated antihypertensive medication with a favorable safety profile compared to other ACE inhibitors. However, a lack of ample recent clinical trials and post-marketing data investigating the efficacy of quinapril in large cohorts has resulted in limited use in clinical practice. Quinapril may be an effective antihypertensive option for elderly populations as well as those who cannot tolerate the side effects profiles of other ACE inhibitors and as an additional treatment option for patients with heart failure with preserved ejection fraction.

Non-random distribution of deleterious mutations in the DNA and protein-binding domains of IRF6 are associated with Van Der Woude syndrome.

BACKGROUND: The development of the face occurs during the early days of intrauterine life by the formation of facial processes from the first Pharyngeal arch. Derangement in these well-organized fusion events results in Orofacial clefts (OFC). Van der Woude syndrome (VWS) is one of the most common causes of syndromic cleft lip and/or palate accounting for 2% of all cases. Mutations in the IRF6 gene account for 70% of cases with the majority of these mutations located in the DNA-binding (exon 3, 4) or protein-binding domains (exon 7-9). The current study was designed to update the list of IRF6 variants reported for VWS by compiling all the published mutations from 2013 to date as well as including the previously unreported VWS cases from Africa and Puerto Rico. METHODS: We used PubMed with the search terms; "Van der Woude syndrome," "Popliteal pterygium syndrome," "IRF6," and "Orofacial cleft" to identify eligible studies. We compiled the CADD score for all the mutations to determine the percentage of deleterious variants. RESULTS: Twenty-one new mutations were identified from nine papers. The majority of these mutations were in exon 4. Mutations in exon 3 and 4 had CADD scores between 20 and 30 and mutations in exon 7-9 had CADD scores between 30 and 40. The presence of higher CADD scores in the protein-binding domain (exon 7-9) further confirms the crucial role played by this domain in the function of IRF6. In the new cases, we identified five IRF6 mutations, three novel missense mutations (p.Phe36Tyr, p.Lys109Thr, and p.Gln438Leu), and two previously reported nonsense mutations (p.Ser424*and p.Arg250*). CONCLUSION: Mutations in the protein and DNA-binding domains of IRF6 ranked among the top 0.1% and 1% most deleterious genetic mutations, respectively. Overall, these findings expand the range of VWS mutations and are important for diagnostic and counseling purposes.

Knowledge, attitude and practice of Sudanese pharmacist with regard to management of diabetes during Ramadan: A cross-sectional survey.

BACKGROUND: Fasting during Ramadan for some individuals with diabetes may lead to complications. Pharmacists may assist in dose adjustment and compliance with medication during Ramadan. Therefore, the aim of this study was to assess the knowledge, attitude and practice of Sudanese community pharmacists in the management of diabetes during Ramadan. METHOD: A cross-sectional study from April to June 2017, included 330 pharmacies in Khartoum state. The sampling technique was done by two methods using stratified and systematic methods for seven localities of Khartoum State. The community pharmacists were assessed in their knowledge about Medication regimen adjustment (MRA), diabetes risk stratification and the condition in which the fasting diabetic patient have to stop their fast. RESULTS: The total response rate was 311(94.2%), and the females were 203(65.3%). Pharmacists mean age was 27.6 (SD = 5.9), ranged between 21-62 years. Importantly, more than 75% of the Pharmacists have sufficient knowledge of both identifying high-risk individuals and whether they need to break their fasting. The practice questions answered correctly by more than 80% of pharmacists in relation to monitor blood glucose level, undergo meal planning to avoid hypoglycemia and dehydration during prolong fasting hours and to undergo meal choices to avoid postprandial hyperglycemia. Importantly, 56.9% community pharmacists advised individuals with diabetes about physical activity. The barriers that hindering the proper counseling was attributed to the Lack of knowledge (71.4%). MRA was reported as highly important by (56.6%) and extremely important by (39.2%). The confidence of knowledge about MRA was reported by 52.1%. CONCLUSION: This study showed that pharmacists had sufficient knowledge, positive attitude and good practice about diabetes management during Ramadan.
