Anthropometric Predictors of Health-Related Quality of Life in Obese Patients Attending a Tertiary Hospital in Nnewi, South-East Nigeria: A Cross-Sectional Study.

BACKGROUND: Obesity as a disorder with excess body fat directly decreases quality of life. While Body Mass Index (BMI) has been used largely in health studies as a measure of obesity, it is largely unable to differentiate between body fat and lean body mass, hence other anthropometric measures can be used to assess body fat. OBJECTIVE: To determine the association of anthropometric indicators with health-related quality of life (HRQoL) in obese adults. MATERIALS AND METHODS: A cross-sectional study of obese adults (BMI ≥30kg/m2) attending the general outpatient clinic was conducted over four months. The quality of life was assessed using the short form-36 (SF-36) questionnaire. The anthropometric indicators used were BMI, waist circumference (WC), waist hip ratio (WHR), and waist-height ratio (WHtR). RESULTS: Physical component summary (PCS) was significantly related to BMI, WHtR, and WC. After adjusting for co-variables (gender, age, occupation, and marital status), they remained significantly associated with PCS. Mental component summary (MCS) was significantly related to BMI, WHtR, and WC. After adjusting for the known determinants of HRQoL, only BMI remained significantly associated with MCS (P = -0.004; r = -0.146). When all the indicators were included in the same regression model, no anthropometric indicator was significantly related to MCS while only WHtR was significantly associated with PCS (P = 0.001; r = -0.465). CONCLUSION: HRQoL in obese patients is related to measures of body fat. The physical and mental components of health-related quality of life are correlated differently with the various anthropometric measures of obesity. The WHtR was found to be an independent predictor of the physical component of HRQoL.

Modelling Disease Progression of Multiple Sclerosis in a South Wales Cohort.

OBJECTIVES: The objective of this study was to model multiple sclerosis (MS) disease progression and compare disease trajectories by sex, age of onset, and year of diagnosis. STUDY DESIGN AND SETTING: Longitudinal EDSS scores (20,854 observations) were collected for 1,787 relapse-onset MS patients at MS clinics in South Wales and modelled using a multilevel model (MLM). The MLM adjusted for covariates (sex, age of onset, year of diagnosis, and disease-modifying treatments), and included interactions between baseline covariates and time variables. RESULTS: The optimal model was truncated at 30 years after disease onset and excluded EDSS recorded within 3 months of relapse. As expected, older age of onset was associated with faster disease progression at 15 years (effect size (ES): 0.75; CI: 0.63, 0.86; p: <0.001) and female-sex progressed more slowly at 15 years (ES: -0.43; CI: -0.68, -0.18; p: <0.001). Patients diagnosed more recently (defined as 2007-2011 and >2011) progressed more slowly than those diagnosed historically (<2006); (ES: -0.46; CI: -0.75, -0.16; p: 0.006) and (ES: -0.95; CI: -1.20, -0.70; p: <0.001), respectively. CONCLUSION: We present a novel model of MS outcomes, accounting for the non-linear trajectory of MS and effects of baseline covariates, validating well-known risk factors (sex and age of onset) associated with disease progression. Also, patients diagnosed more recently progressed more slowly than those diagnosed historically.

The Evolution of Hypertension Guidelines Over the Last 20+ Years: A Comprehensive Review.

Hypertension is the most common modifiable risk factor for cardiovascular and cerebrovascular diseases. In the last two decades, the guidelines have evolved tremendously from areas with no recommendations for screening or treatment to targeted recommendations for some at-risk groups. We sought to go through the literature that provided guidelines for the management of hypertension at any point in time over the last 22 years from 2000 to 2022. We searched four databases: PubMed, Embase, Google Scholar, and Cochrane, using specified search terms. The keywords used were "hypertension" and "guidelines." We combined them using the Boolean operators (AND, OR) and searched for articles. A total of 2461 publications were initially identified; 348 publications were excluded after screening for full-text availability. The full-text articles were further filtered based on title and abstract screening. Following this, a total of 1443 articles were excluded. The remaining 670 full-text articles were assessed for eligibility. Of the 670 full-text articles, 480 were excluded based on exclusion criteria, and following the full-text article screening, 190 articles met the final inclusion criteria. Most of these guideline evolutions concerned establishing and adjusting thresholds for the subgroups of the elderly population and patients with diabetic kidney disease, chronic kidney disease, and stroke. Furthermore, the medications of choice are now guided by the stage of disease, presence or absence of comorbidities, and other relevant information, as opposed to ethnicity, which was previously a heavy yardstick for medication choice.

Arrhythmogenic Cardiomyopathy: A Review of a Rare Case of Biventricular Phenotype.

Arrhythmogenic cardiomyopathy is a rare hereditary structural heart disease, with various phenotypes, which mostly affects the right ventricle of the heart, resulting in fibrofatty replacement of the heart muscles and a proclivity to create spontaneous malignant cardiac arrhythmias that may lead to sudden death. Most previous reports were noted on young people. We report a case of its biventricular phenotype in a 61-year-old heavy truck driver who has a current medical history of diabetes mellitus and smoking and was incidentally diagnosed based on the Padua criteria after presenting to the hospital with complaints of lightheadedness and syncope. He eventually had an implantable cardioverter defibrillator, hence preventing death. We were able to correctly diagnose the case and prevent sudden cardiac death by instituting the necessary management.

An Unusual Case of Giant Cell Arteritis.

Giant cell arteritis (GCA), also known as temporal arteritis (TA), is a systemic autoimmune inflammation of medium and large arteries. It is the most common vasculitis affecting adults older than 50, with an incidence of 20/100,000 and an average age of onset of 70. Typically, patients initially present with new-onset headaches, visual changes and disturbances, jaw claudication, arthralgias, and tender or swollen temporal or occipital arteries. Our patient is a 73-year-old male who presented to the emergency room with 10 days of bilateral headache radiating to the occipital area associated with fevers, persistent chills, generalized weakness, and a headache described as constant, dull, 9 out of 10 pain, and minor pain with neck flexion. Lab work revealed an elevated erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). The patient had tender palpation to his temples and due to a high suspicion of giant cell arteritis, he was started on high-dose steroids with rapid relief of his symptoms. Biopsy showed evidence of active non-granulomatous vasculitis and confirmed bilateral temporal arteritis within the context of the clinical setting. GCA patients are more likely to be women and typically present with unilateral headache (66% of GCA), jaw claudication (50%), fevers (50%), and transient visual loss (16-54%). Here, we describe a 73-year-old male with a past medical history of cerebral vascular accident (CVA), diabetes, and cancer that presented with 10 days of bilateral headaches and fevers. Unlike the usual presentation, our patient denied any vision and joint pain changes, and the temporal arteries were not stiff to palpation. This patient presentation is unique to previous reports in the limited display of symptoms and absence of the most commonly associated manifestations. Although his presentation supported GCA, the features of elevated ESR and CRP, headache, and fever were too general to diagnose GCA exclusively, and his additional symptoms of rhinorrhea and sinus pain more likely supported infection. Our case indicates the importance of maintaining a high index of clinical suspicion for GCA in the elderly population presenting with headaches and elevated ESR and CRP. GCA, also known as temporal arteritis (TA), is a systemic autoimmune inflammation of medium and large arteries. Typically, patients initially present with new-onset headaches, visual changes and disturbances, jaw claudication, arthralgias, and tender or swollen temporal or occipital arteries. Diagnosis requires high clinical suspicion, and treatment revolves around high doses of steroids.

Comparison of Antifungal Activity of Bacillus Strains against Fusarium graminearum In Vitro and In Planta.

Fusarium graminearum (Fg) causes Fusarium head blight (FHB) disease in wheat and barley. This pathogen produces mycotoxins including deoxynivalenol (DON), the T-2 and fumorisin B1. Translocation of the mycotoxins in grains causes important losses in yields and contributes to serious health problems in humans and livestock. We tested the Bacillus strains, two commercial, QST713 (Serenade®) and FZB24 (TAEGRO®) and one non-commercial strain EU07 as microbial biological control agents against the F. graminearum strain Fg-K1-4 both in vitro and in planta. The EU07 strain showed better performance in suppressing the growth of Fg-K1-4. Cell-free bacterial cultures displayed significant antagonistic activity on Fg-K1-4. Remarkably, heat and proteinase K treatment of bacterial broths did not reduce the antagonistic activity of Bacillus cultures. DON assays showed that Bacillus strain was not affected by the presence of DON in the media. Leaf and head infection assays using Brachypodium distachyon (Bd-21) indicated that EU07 inhibits Fg-K1-4 growth in vivo and promotes plant growth. Overall, the EU07 strain performed better, indicating that it could be explored for the molecular investigations and protection of cereal crops against FHB disease.

Association Between Community-Level Violent Crime and Cardiovascular Mortality in Chicago: A Longitudinal Analysis.

Background Violent crime has recently increased in many major metropolitan cities in the United States. Prior studies suggest an association between neighborhood crime levels and cardiovascular disease, but many have been limited by cross-sectional designs. We investigated whether longitudinal changes in violent crime rates are associated with changes in cardiovascular mortality rates at the community level in one large US city-Chicago, IL. Methods and Results Chicago is composed of 77 community areas. Age-adjusted mortality rates by community area for cardiovascular disease, stroke, and coronary artery disease from 2000 to 2014, aggregated at 5-year intervals, were obtained from the Illinois Department of Public Health Division of Vital Records. Mean total and violent crime rates by community area were obtained from the City of Chicago Police Data Portal. Using a 2-way fixed effects estimator, we assessed the association between longitudinal changes in violent crime and cardiovascular mortality rates after accounting for changes in demographic and economic variables and secular time trends at the community area level from 2000 to 2014. Between 2000 and 2014, the median violent crime rate in Chicago decreased from 3620 per 100 000 (interquartile range [IQR], 2256, 7777) in the 2000 to 2004 period to 2390 (IQR 1507, 5745) in the 2010 to 2014 period (P=0.005 for trend). In the fixed effects model a 1% decrease in community area violent crime rate was associated with a 0.21% (95% CI, 0.09-0.33) decrease in cardiovascular mortality rates (P=<0.001) and a 0.19% (95% CI, 0.04-0.33) decrease in coronary artery disease mortality rates (P=0.01). There was no statistically significant association between change in violent crime and stroke mortality rates (-0.17% [95% CI, -0.42 to 0.08; P=0.18]). Conclusions From 2000 to 2014, a greater decrease in violent crime at the community area level was associated with a greater decrease in cardiovascular and coronary artery disease mortality rates in Chicago. These findings add to the growing evidence of the impact of the built environment on health and implicate violent crime exposure as a potential social determinant of cardiovascular health. Targeted investment in communities to decrease violent crime may improve community cardiovascular health.

European trends in cervical cancer mortality in relation to national screening programs, 1985-2014.

BACKGROUND: Cervical cancer is the fourth leading oncological cause of death in women. Variable trends in cervical cancer mortality have been observed across Europe, despite the widespread adoption of screening programs. This variability has previously been attributed to heterogeneity in the quality of screening programs. METHODS: Age-standardized cervical cancer death rates for European countries between 1985 and 2014 were analyzed using Joinpoint regression. Countries were dichotomized based on year of implementation and population invitational coverage of national population-based cervical cancer screening programs. National cervical cancer mortality trends during the study period were compared based on this classification. RESULTS: Decreasing trends in mortality were observed in all European countries with the specific exceptions of Bulgaria, Greece and Latvia. The highest rates of cervical cancer mortality throughout the study period were in Romania (16.0-14.9/100,000) and the lowest rates in Italy (1.4-1.2/100,000). The greatest percentage decline in mortality was observed in the United Kingdom and the greatest absolute reduction in mortality was seen in Hungary. European countries which implemented a national population-based cervical cancer screening program prior to 2009 demonstrated greater improvements in cervical cancer mortality outcomes compared to those that did not (p = 0.016). CONCLUSION: Cervical cancer mortality is improving in most European countries; however, substantial variation remains. Trends in mortality were associated with the time of implementation of national population-based cervical screening programs.

Automated Procedure Logs for Cardiology Fellows: A New Training Paradigm in the Era of Electronic Health Records.

BACKGROUND: Procedural experience for residents and fellows is critical for achieving competence, and documentation of procedures performed is required. Procedure logs serve as the record of this experience, but are commonly generated manually, require substantial administrative effort, and cannot be corroborated for accuracy. OBJECTIVE: We developed and implemented a structured clinical-educational report template (CERT), which automatically generates procedure logs directly from the clinical record. METHODS: Our CERT aimed to replace the post-procedure note template for our cardiac catheterization laboratory and was incorporated into the electronic health record system. Numbers of documented procedures in automated CERT-derived procedure logs over a 1-year post-intervention period (2018-2019) were compared to manual logs and corrected for clinical volume changes. The CERT's impact on fellowship experience was also assessed. RESULTS: Automated CERT procedure logs increased weekly procedural documentation over manual procedure logs for total procedures (24.2 ± 6.1 vs 17.1 ± 6.8, P = .007), left heart catheterizations (14.5 ± 3.6 vs 10.8 ± 4.2, P = .039), total procedural elements (40.2 ± 11.4 versus 20.9 ± 12.5, P < .001), and captured procedural details not previously documented. The CERT also reduced self-reported administrative time and improved fellowship experience. CONCLUSIONS: A novel CERT allows procedure logs to be automatically derived from the clinical record and increased the number of documented procedures, compared to manual logging. This innovation ensures an accurate record of procedural experience and reduces self-reported non-educational administrative time for cardiology fellows.

A Mobile App to Facilitate Socially Distanced Hospital Communication During COVID-19: Implementation Experience.

BACKGROUND: COVID-19 has significantly altered health care delivery, requiring clinicians and hospitals to adapt to rapidly changing hospital policies and social distancing guidelines. At our large academic medical center, clinicians reported that existing information on distribution channels, including emails and hospital intranet posts, was inadequate to keep everyone abreast with these changes. To address these challenges, we adapted a mobile app developed in-house to communicate critical changes in hospital policies and enable direct telephonic communication between clinical team members and hospitalized patients, to support social distancing guidelines and remote rounding. OBJECTIVE: This study aimed to describe the unique benefits and challenges of adapting an app developed in-house to facilitate communication and remote rounding during COVID-19. METHODS: We adapted moblMD, a mobile app available on the iOS and Android platforms. In conjunction with our Hospital Incident Command System, resident advisory council, and health system innovation center, we identified critical, time-sensitive policies for app usage. A shared collaborative document was used to align app-based communication with more traditional communication channels. To minimize synchronization efforts, we particularly focused on high-yield policies, and the time of last review and the corresponding reviewer were noted for each protocol. To facilitate social distancing and remote patient rounding, the app was also populated with a searchable directory of numbers to patient bedside phones and hospital locations. We monitored anonymized user activity from February 1 to July 31, 2020. RESULTS: On its first release, 1104 clinicians downloaded moblMD during the observation period, of which 46% (n=508) of downloads occurred within 72 hours of initial release. COVID-19 policies in the app were reviewed most commonly during the first week (801 views). Users made sustained use of hospital phone dialing features, including weekly peaks of 2242 phone number dials, 1874 directory searches, and 277 patient room phone number searches through the last 2 weeks of the observation period. Furthermore, clinicians submitted 56 content- and phone number-related suggestions through moblMD. CONCLUSIONS: We rapidly developed and deployed a communication-focused mobile app early during COVID-19, which has demonstrated initial and sustained value among clinicians in communicating with in-patients and each other during social distancing. Our internal innovation benefited from our team's familiarity with institutional structures, short feedback loops, limited security and privacy implications, and a path toward sustainability provided by our innovation center. Challenges in content management were overcome through synchronization efforts and timestamping review. As COVID-19 continues to alter health care delivery, user activity metrics suggest that our solution will remain important in our efforts to continue providing safe and up-to-date clinical care.

SALAD-BAAR: A numerical risk score for hospital admission or emergency department presentation in ambulatory patients with cardiovascular disease.

BACKGROUND: While many interventions to reduce hospital admissions and emergency department (ED) visits for patients with cardiovascular disease have been developed, identifying ambulatory cardiac patients at high risk for admission can be challenging. HYPOTHESIS: A computational model based on readily accessible clinical data can identify patients at risk for admission. METHODS: Electronic health record (EHR) data from a tertiary referral center were used to generate decision tree and logistic regression models. International Classification of Disease (ICD) codes, labs, admissions, medications, vital signs, and socioenvironmental variables were used to model risk for ED presentation or hospital admission within 90 days following a cardiology clinic visit. Model training and testing were performed with a 70:30 data split. The final model was then prospectively validated. RESULTS: A total of 9326 patients and 46 465 clinic visits were analyzed. A decision tree model using 75 patient characteristics achieved an area under the curve (AUC) of 0.75 and a logistic regression model achieved an AUC of 0.73. A simplified 9-feature model based on logistic regression odds ratios achieved an AUC of 0.72. A further simplified numerical score assigning 1 or 2 points to each variable achieved an AUC of 0.66, specificity of 0.75, and sensitivity of 0.58. Prospectively, this final model maintained its predictive performance (AUC 0.63-0.60). CONCLUSION: Nine patient characteristics from routine EHR data can be used to inform a highly specific model for hospital admission or ED presentation in cardiac patients. This model can be simplified to a risk score that is easily calculated and retains predictive performance.

Social representation of abuse of persons with severe mental illness in Jakiri, Cameroon: A qualitative study.

BACKGROUND: People with mental illness are vulnerable to abuse in the community. Cultural and social practices may be contributory. AIM: To explore the social representation of abuse of persons with mental illness among the inhabitants of Jakiri municipality in Cameroon. METHOD: This was a qualitative study based on the Theory of Reasoned Action, conducted in 2018 among 11 inhabitants of Jakiri municipality, aged above 18 years and who had lived in the town for at least 2 years. In-depth face-to-face semi-structured interviews were conducted. Data were analyzed using the basic thematic approach. RESULTS: The belief that mental illness is incurable, a curse from the gods, a result of witchcraft, and a punishment for violation of core social norms were identified as the reasons for physical violence against persons with mental illness. Beliefs that persons with mental illness were disorganized, destructive, physically aggressive, and dependent on others were identified as reasons for emotional abuse. CONCLUSION: A misconception of mental illness was the major underlying factor for the abuse of persons with mental illness.

Evaluation of drinking water quality using heavy metal pollution indexing models in an agrarian, non-industrialised area of South-East Nigeria.

The objectives of this study were to evaluate the physicochemical properties of drinking water sources at Ihiala, Nigeria, and to assess the water quality using the heavy metal pollution index, heavy metal evaluation index and contamination index models. Physicochemical parameters like pH, total hardness, total dissolved solids, nitrate, cyanide, residual chlorine and six metals (Al, Cd, Cr, Cu, Pb and Ni) were analyzed in the water samples, and heavy metal pollution indices computed. The spring and borehole waters had better organoleptic properties compared to stream, river and sachet waters. Total hardness, pH and nitrate were the major nonmetallic contributors to the poor water quality. The mean pollution indices were: heavy metal pollution index (HPI) 143.02 ± 71.16, heavy metal evaluation index (HEI) 7.53 ± 4.12 and contamination index (Cd) 1.53 ± 4.12. Sixty percent of the samples exceeded the critical HPI value of 100. There was significant (P < 0.01) positive correlation between HPI and Cd, HPI and HEI (r = 0.886) and HEI and Cd (r = 1.000). Lead contributed most to heavy metal pollution of water in the region. The quality of most water sources in Ihiala is not good for drinking.

Association of Rising Violent Crime With Blood Pressure and Cardiovascular Risk: Longitudinal Evidence From Chicago, 2014-2016.

BACKGROUND: The purpose of this study was to examine the longitudinal association between rising violent crime and elevated blood pressure (BP). METHODS: We analyzed 217,816 BP measurements from 17,783 adults during a temporal surge in violent crime in Chicago (2014-2016). Serial observations were abstracted from the electronic health record at an academic medical center and paired to the City of Chicago Police Data Portal. The violent crime rate (VCR) was calculated as the number of violent crimes per 1,000 population per year for each census tract. Longitudinal multilevel regression models were implemented to assess elevated BP (systolic BP ≥ 140 mm Hg or diastolic BP ≥ 90 mm Hg) as a function of the VCR, adjusting for patient characteristics, neighborhood characteristics, and time effects. Secondary dependent measures included elevated heart rate, obesity, missed outpatient appointments, all-cause hospital admissions, and cardiovascular hospital admissions. RESULTS: At baseline, the median VCR was 41.3 (interquartile range: 15.2-66.8), with a maximum rise in VCR of 59.1 over the 3-year surge period. A 20-unit rise in the VCR was associated with 3% higher adjusted odds of having elevated BP (95% confidence interval [CI]: 1.01-1.06), 8% higher adjusted odds of missing an outpatient appointment (95% CI: 1.03-1.13), and 6% higher adjusted odds of having a cardiovascular-related hospital admission (95% CI: 1.01-1.12); associations were not significant for elevated heart rate and obesity. CONCLUSION: Rising violent crime was associated with increased BP during a temporal crime surge.

Abrogation of Hepatic Damage Induced by Anticancer Drug Methotrexate by Zobo (Hibiscus sabdariffa extract) Supplementation via Targeting Oxidative Hepatotoxicity in Rats.

Clinical use of methotrexate (MTX) in cancer chemotherapy is limited due to its side effects, notably associated with increased oxidative stress and hepatotoxicity. Zobo is an aqueous extract of Hibiscus sabdariffa known to contain natural antioxidants. The present study investigated the hepatoprotective effect of zobo drink (ZD) on MTX-induced oxidative stress and hepatotoxicity in rats. Rats randomized to control group received distilled water orally; MTX group received intraperitoneal (ip) injection of MTX (20 mg/kg) on day 11; ZD + MTX group was administered ZD (10 ml/kg) for 14 days and was injected with MTX on day 11. Three days after MTX injection, enzyme markers of liver injury, protein profile, and bilirubin were assessed in serum. Hepatic activities of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) and level of lipid peroxidation were estimated. Histopathological changes were carried out on the liver tissue. MTX induced prominent oxidative hepatotoxicity demonstrated by significant (p < .01) increases in serum liver enzymes and bilirubin, while protein profile was markedly reduced (p < .05). Hepatic activities of SOD, CAT, and GPx considerably decreased, whereas lipid peroxidation increased significantly in the MTX group compared to control. By contrast, ZD administration attenuated and restored the markers of liver injury, hepatic antioxidant enzymes, and lipid peroxidation near to control, while histopathological alterations were ameliorated compared to the MTX group. ZD affords superior protection against MTX-induced oxidative hepatotoxicity via improvement in antioxidant defense systems in rats. ZD could be a potent natural product against hepatotoxicity associated with MTX chemotherapy in cancer patients.

Home Inotropes in Patients Supported with Left Ventricular Assist Devices.

There is little data outlining the use of outpatient inotropic medications in patients with existing left ventricular assist devices (LVADs). This case series explores this patient population and seeks to define the indications, complications, and safety of dual support. A retrospective chart review was conducted for all patients on LVAD and then subsequently started on home inotropes post device implant. Eight patients met inclusion criteria. The indications for inotropes were right ventricular failure, aortic insufficiency with biventricular failure, LVAD thrombosis with contraindication to device exchange, and cannula malposition with elevated pulmonary vascular resistance. Mean duration of combined support was 273 ± 170 days. Cardiac index improved from 1.96 ± 0.24 to 2.31 ± 0.35 L/min/m(2) after inotropes (p = 0.02). There was no change in hospital admissions. The most common reason for readmission was heart failure symptoms, followed by bleeding. Five patients died during the study period, one underwent heart transplant, and two remain on inotropic support. Home inotropes may be indicated in selected continuous flow left ventricular assist device (CF-LVAD) patients with refractory right ventricular failure or impaired LVAD function. Inotropes can improve hemodynamics and provide palliation of symptoms. However, long-term inotrope use does not reduce hospital readmissions and is associated with multiple complications related to the need for an indwelling intravenous line.

Repeatedly heated palm kernel oil induces hyperlipidemia, atherogenic indices and hepatorenal toxicity in rats: Beneficial role of virgin coconut oil supplementation.

BACKGROUND: The literature reports that the health benefits of vegetable oil can be deteriorated by repeated heating, which leads to lipid oxidation and the formation of free radicals. Virgin coconut oil (VCO) is emerging as a functional food oil and its health benefits are attributed to its potent polyphenolic compounds. We investigated the beneficial effect of VCO supplementation on lipid profile, liver and kidney markers in rats fed repeatedly heated palm kernel oil (HPO). METHODS: Rats were divided into four groups (n = 5). The control group rats were fed with   a normal diet; group 2 rats were fed a 10% VCO supplemented diet; group 3 administered 10 ml HPO/kg b.w. orally; group 4 were fed 10% VCO + 10 ml HPO/kg for 28 days. Subsequently, serum markers of liver damage (ALT, AST, ALP and albumin), kidney damage (urea, creatinine and uric acid), lipid profile and lipid ratios as cardiovascular risk indices were evaluated. RESULTS: HPO induced a significant increase in serum markers of liver and kidney damage as well as con- comitant lipid abnormalities and a marked reduction in serum HDL-C. The lipid ratios evaluated for atherogenic and coronary risk indices in rats administered HPO only were remarkably higher than control. It was observed that VCO supplementation attenuated the biochemical alterations, including the indices of cardiovascular risks. CONCLUSIONS: VCO supplementation demonstrates beneficial health effects against HPO-induced biochemical alterations in rats. VCO may serve to modulate the adverse effects associated with consumption of repeatedly heated palm kernel oil.

Genome-wide association study for agronomic and physiological traits in spring wheat evaluated in a range of heat prone environments.

KEY MESSAGE: We identified 27 stable loci associated with agronomic traits in spring wheat using genome-wide association analysis, some of which confirmed previously reported studies. GWAS peaks identified in regions where no QTL for grain yield per se has been mapped to date, provide new opportunities for gene discovery and creation of new cultivars with desirable alleles for improving yield and yield stability in wheat. We undertook large-scale genetic analysis to determine marker-trait associations (MTAs) underlying agronomic and physiological performance in spring wheat using genome-wide association studies (GWAS). Field trials were conducted at seven sites in three countries (Sudan, Egypt, and Syria) over 2-3 years in each country. Twenty-five agronomic and physiological traits were measured on 188 wheat genotypes. After correcting for population structure and relatedness, a total of 245 MTAs distributed over 66 loci were associated with agronomic traits in individual and mean performance across environments respectively; some of which confirmed previously reported loci. Of these, 27 loci were significantly associated with days to heading, thousand kernel weight, grain yield, spike length, and leaf rolling for mean performance across environments. Despite strong QTL by environment interactions, eight of the loci on chromosomes 1A, 1D, 5A, 5D, 6B, 7A, and 7B had pleiotropic effects on days to heading and yield components (TKW, SM-2, and SNS). The winter-type alleles at the homoeologous VRN1 loci significantly increased days to heading and grain yield in optimal environments, but decreased grain yield in heat prone environments. Top 20 high-yielding genotypes, ranked by additive main effects and multiplicative interaction (AMMI), had low kinship relationship and possessed 4-5 favorable alleles for GY MTAs except two genotypes, Shadi-4 and Qafzah-11/Bashiq-1-2. This indicated different yield stability mechanisms due to potentially favorable rare alleles that are uncharacterized. Our results will enable wheat breeders to effectively introgress several desirable alleles into locally adapted germplasm in developing wheat varieties with high yield stability and enhanced heat tolerance.

Missed opportunities in the prevention of mother-to-child transmission of HIV infection: experience from a national programme in Nigeria.

An analysis of validated National Prevention of Mother-to-Child Transmission (PMTCT) data from 2008 to 2014 showed that Nigeria has recorded steady progress. However, to achieve elimination of mother-to-child transmission of HIV, service scale-up and active testing of pregnant women are required, as a large number of HIV-infected women in Nigeria are not aware of their HIV status. Focusing on efforts that will improve access and uptake of antenatal care/PMTCT services will significantly reduce new infant HIV infection.

An Audit of Malignant Oro-facial Tumors Presenting at a Tertiary Hospital in Lagos.

Oro-facial malignancies are reported to have a high mortality and morbidity, this is further worsened when patient report late. To analyze the malignant oro-facial lesions seen at a Hospital in the Lagos, Nigeria. Successive patients that presented in the hospital and met criteria of study during 15 months period were recruited into the study. Demographics, clinical variables, and treatment provided for each patient in the hospital was recorded. Data collected were presented as tables and percentages. There were 36 cases seen, their ages ranged from 10 to 72 years (median 49 years), and there were 21 males and 15 females. Time lapse before presentation to the clinic ranged from 2 to 30 months, mean (9.9 (±5.5 months and the largest dimension of lesions at presentation ranged from 2 cm to 12 cm (mean 6.4 ± 2.0 cm). Most common site of presentation was posterior tongue (16.7%; 6/36) and Squamous cell carcinoma (41.6%; 15/36) was the most common histopathologic diagnosis. Twenty-three patients (63.9%; 23/36) had primary surgeries in the hospital. Patients seen in this case series generally reported late with large lesions.
