The Effect of Music on Operative Anxiety markers in patients undergoing Cataract Surgery: Adual centre cross-sectional comparative study.

OBJECTIVE: To determine the effect of intraoperative music on various markers of anxiety among adult patients undergoing small incision cataract surgery. METHODS: This was a hospital-based, age-sex matched, comparative cross-sectional study of consenting 144 adult participants aged 46 years and above with operable, age-related cataracts undergoing small incision cataract surgery under local anaesthesia in two ophthalmic centres. All participants were allotted into two equal groups consisting of 72 participants in the experimental group (exposed to music of their choice) and 72 participants in the control group (no music exposure). Blood pressure, pulse rate and salivary cortisol assay levels were measured. Data obtained were analyzed using statistical package for social sciences (IBM SPSS version 23.0). RESULTS: One hundred and forty-four participants with total male-to-female ratio of 1:2.1 were studied. Gender ratio was 1:2.3 and 1:2.0 and the median age (Q1-Q3) of 65.00 (55.5-71.5) years and 65.50 (56.5-72.0) years for music and non-music groups respectively. Participants in the music group showed a statistically significant reduction in systolic blood pressure, diastolic blood pressure and pulse rate (p < 0.05) except at baseline. The mean value salivary cortisol level showed a statistically significant decrease in both groups from baseline for music (23.91ng/ml) and nonmusic (19.12ng/ml) group (p<0.001) respectively. Similarly, participants in the music group showed a statistically significant reduction of Spielberger State anxiety score after music intervention compared to control (p<0.001). CONCLUSIONS: This study demonstrated the effectiveness of music in decreasing anxiety indicators during cataract surgery with markers like salivary cortisol assay, pulse rate, systolic and diastolic blood pressure.

OBJECTIF: Déterminer l'effet de la musique intra-opératoire sur divers marqueurs d'anxiété chez les patients adultes subissant une chirurgie de la cataracte par petite incision. MÉTHODES: Il s'agissait d'une étude transversale comparative, basée à l'hôpital, appariée selon l'âge et le sexe, portant sur 144 participants adultes consentants âgés de 46 ans et plus, présentant des cataractes liées à l'âge opérables et subissant une chirurgie de la cataracte par petite incision sous anesthésie locale dans deux centres ophtalmologiques. Tous les participants ont été répartis en deux groupes égaux, soit 72 participants dans le groupe expérimental (exposé à de la musique de leur choix) et 72 participants dans le groupe témoin (pas d'exposition à la musique). La pression artérielle, la fréquence cardiaque et les taux de cortisol salivaire ont été mesurés. Les données obtenues ont été analysées à l'aid du logiciel statistique pour les sciences sociales (IBM SPSS version 23.0). RÉSULTATS: Cent quarante-quatre participants avec un rapport total d'hommes à femmes de 1:2,1 ont été étudiés. Le ratio hommes-femmes était de 1:2,3 et 1:2,0, avec un âge médian (Q1-Q3) de 65,00 (55,5-71,5) ans et 65,50 (56,5-72,0) ans pour les groupes musique et non-musique, respectivement. Les participants du groupe musique ont montré une réduction statistiquement significative de la pression artérielle systolique, de la pression artérielle diastolique et de la fréquence cardiaque (p < 0,05) sauf au départ. La valeur moyenne du taux de cortisol salivaire a montré une diminution statistiquement significative dans les deux groupes par rapport au départ pour le groupe musique (23,91 ng/ml) et le groupe non-musique (19,12 ng/ml) (p <0,001) respectivement. De même, les participants du groupe musique ont montré une réduction statistiquement significative du score d'anxiété à l'état de Spielberger après l'intervention musicale par rapport au groupe témoin (p <0,001). CONCLUSIONS: Cette étude a démontré l'efficacité de la musique dans la diminution des indicateurs d'anxiété pendant la chirurgie de la cataracte, avec des marqueurs tels que le dosage du cortisol salivaire, la fréquence cardiaque, la pression artérielle systolique et diastolique.

Non-communicable disease co-morbidity and associated factors in tuberculosis patients: A cross-sectional study in Gabon.

BACKGROUND: There are only limited data from resource-limited settings available on the prevalence of non-communicable diseases and associated risk factors of tuberculosis patients. This study investigated non-communicable disease co-morbidity in tuberculosis patients from Moyen Ogooué Province, Gabon. METHODS: All patients aged 18 years or older consulting for tuberculosis (TB) symptoms in Gabon's Moyen Ogooué province and neighbouring provinces from November 2018 to November 2020 were screened for diabetes mellitus, hypertension, and risk factors thereof (obesity, dyslipidaemia, smoking and alcohol consumption). Logistic regression was performed to identify factors associated with TB-diabetes and TB-hypertension co-morbidities. FINDINGS: Of 583 patients included, 227 (39%) were diagnosed with tuberculosis. In tuberculosis-confirmed patients, the prevalences of hypertension and diabetes were 16·3% and 12·8%, respectively. The prevalence of diabetes was twice as high in tuberculosis patients compared to non-tuberculosis patients. Factors independently associated with hypertension-tuberculosis co-morbidity were age >55 years (aOR=8·5, 95% CI 2·43, 32·6), age 45-54 years (aOR=4.9, 95%CI 1.3-19.8), and moderate alcohol consumption (aOR=2·4; 95% CI 1·02- 5·9), respectively. For diabetes-tuberculosis co-morbidity, age >55 years was positively (aOR=9·13; 95% CI 2·4-39·15), and moderate alcohol consumption inversely associated (aOR=0·26, 95% CI 0·08- 0·73). One-hundred-and-four (46%) of the tuberculosis patients had at least either dyslipidaemia, hypertension, diabetes, or obesity with a majority of newly-diagnosed hypertension and diabetes. INTERPRETATION: Integration of screening of non-communicable diseases and their risk factors during TB assessment for early diagnosis, treatment initiation and chronic care management for better health outcomes should be implemented in all tuberculosis healthcare facilities. FUNDING: This study was supported by WHO AFRO/TDR/EDCTP (2019/893,805) and Deutsches Zentrum für Infektiologie (DZIF/ TTU 02.812).

Datura stramonium abrogates depression- and anxiety-like disorders in mice: possible involvement of monoaminergic pathways in its antidepressant activity.

OBJECTIVES: Ethno-botanical surveys uncovered the use of Datura stramonium in the management of mental health abnormalities. Antidepressant- and anxiolytic-like activities of hydroethanol leaf extract of D. stramonium (HLDS) in mice and its possible mechanism of action were investigated in this study. METHODS: The hole-board test (HBT), open field test (OFT), elevated plus maze test (EPMT), and social interaction test (SIT) were used to investigate the anxiolytic-like activity while forced swim test (FST) and tail suspension test (TST) were employed for the antidepressant effect. Mice were pre-treated orally with purified water (10 mL/kg), bromazepam (1 mg/kg), fluoxetine (20 mg/kg) and D. stramonium (25, 50, 100 and 200 mg/kg). One hour post-treatment, mice were subjected to the various tests. RESULTS: In HBT, D. stramonium increased the head dips and sectional crossings turnover. D. stramonium increased the number of square crossed and rearings/assisted rearings in OFT. DS increased the time spent in open arms of EPM. In SIT, D. stramonium increased the frequency/duration of interactions. In FST and TST, D. stramonium decreased the duration of immobility which were reversed by doxazosin (α1 adrenoceptor antagonist) and ondasentron (5-HT3 receptor antagonist). CONCLUSIONS: HLDS has anxiolytic- and antidepressant-like activities through modulation of serotoninergic and adrenergic neurotransmissions.

Mesh fixation techniques for inguinal hernia repair: an overview of systematic reviews of randomised controlled trials.

PURPOSE: Inguinal hernia repair using surgical mesh is a very common surgical operation. Currently, there is no consensus on the best technique for mesh fixation. We conducted an overview of existing systematic reviews (SRs) of randomised controlled trials to compare the risk of chronic pain and recurrence following open and laparoscopic inguinal hernia repairs using various mesh fixation techniques. METHODS: We searched major electronic databases in April 2020 and assessed the methodological quality of identified reviews using the AMSTAR-2 tool. RESULTS: We identified 20 SRs of variable quality assessing suture, self-gripping, glue, and mechanical fixation. Across reviews, the risk of chronic pain after open mesh repair was lower with glue fixation than with suture and comparable between self-gripping and suture. Incidence of chronic pain was lower with glue fixation than with mechanical fixation in laparoscopic repairs. There were no significant differences in recurrence rates between fixation techniques in open and laparoscopic mesh repairs, although fewer recurrences were reported with suture. Many reviews reported wide confidence intervals around summary estimates. Despite no clear evidence of differences among techniques, two network meta-analyses (one assessing open repairs and one laparoscopic repairs) ranked glue fixation as the best treatment for reducing pain and suture for reducing the risk of recurrence. CONCLUSION: Glue fixation may be effective in reducing the incidence of chronic pain without increasing the risk of recurrence. Future research should consider both the effectiveness and cost-effectiveness of fixation techniques alongside the type of mesh and the size and location of the hernia defect.

Prevalence and Risk Factors Associated with Diabetes Mellitus in Public Secondary Schools Teachers in Ekiti State

Background: Diabetes Mellitus is a non-communicable disease and a leading cause of morbidity and mortality in the world. The estimated prevalence of diabetes in Africa is 1% in rural areas and ranges from 5% to 7% in urban sub-Saharan Africa. 3 Nigeria is the most populous country in African and she contributes about one sixth of the Africa's diabetic population. This study is aimed at determining the prevalence of diabetes mellitus and accessing its risk factors among public secondary school teachers in Ekiti State. Methodology: This survey is a cross-sectional study carried out among 357 public school teachers in Ekiti State using a multi stage sampling technique. Data was gathered using a semi structured questionnaire and Accu Check Glucometer machine for Fasting Blood Sugar. Analysis was done using SPSS version 23 and level of significance was taken as P = 0.05. Result: Mean age was 42.9±9.2 years. Prevalence of Diabetes Mellitus was 5.6%. Family history (15%), Alcohol intake (14.0%) and smoking (11.2%) were major risk factors in the respondents. Poor vision is the main complication being experienced by the respondents (40.3%). Predictors of Diabetes Mellitus as found by this study include increasing age (starting from above 40years), cigarette smoking, alcohol intake and positive family history. Conclusion: Prevalence of Diabetes Mellitus is high compared to what it was before. Alcohol intake, smoking and family history were major risk factors while poor vision is the commonest complication. It is recommended that all efforts must be made to put in mechanism that will halt this undesired progression through control of risk factors.

Assessment of Willingness to pay for Community-Based Health Insurance among Artisans in a selected Community of Ekiti State, Southwest Nigeria

Background: Community-based health insurance (CBHI) has emerged as a more efficient and equitable approach to healthcare financing. It was designed to ensure that sufficient resources are made available for members to access effective healthcare. This study assessed the willingness to pay (WTP) for CBHI among artisans in a town in Ekiti State, South West Nigeria. Methods: This was a cross-sectional survey conducted among 416 artisans in a town in Ekiti State. A semi-structured interviewer-administered questionnaire was designed and used for data collection on sociodemographic data and WTP for CBHIS. Data entry and analysis was done using IBM SPSS software version 25.0. Results: The mean age and standard deviation of the respondents was 29.7±10.9 years with male to female ratio of 1:1.4. Most of the respondents were willing to pay (86.3%) and willing to enroll other household members (73.6%) in the CBHI. A large percentage (44.3%) of those willing to pay were ready to pay between ₦1,000-₦5,000 (US$2.63­US$13.16) per year while 39.6% preferred frequency of payment to be annually. Positive predictors of WTP for CBHI were age groups ≥50 years and 40-49 years than <20 years (AOR:13.270, 95%CI: 1.597-110.267; AOR:142.996, 95%CI: 10.689-1913.009). Females than males (AOR:9.155, 95%CI: 3.680-22.775), tertiary level of education than no formal of education (AOR:23.420, 95%CI: 1.648-850.921), no children than ≥5 children (AOR:20.099, 95%CI: 2.705-149.364), earn ≥₦30,000 (US$78.95) than <₦30,000 (AOR:2.248, 95%CI: 1.278-6.499). often and somethings fall ill than seldom fall ill (AOR:6.505, 95%CI: 1.623-26.065; AOR:4.889, 95%CI: 1.674-14.279) Conclusion: WTP for CBHI was high among the artisans, however, there is a variation across the amount and frequency of payment. Therefore, policy that is flexible enough to allow artisans enroll and pay a premium that is affordable, at an acceptable frequency, should be formulated by the Government.

Old unreduced elbow dislocation: Patients' perspectives on outcome of open reduction.

INTRODUCTION: Old unreduced elbow dislocation is not uncommon in developing countries. Many authors have reported outcome of open reduction in the management of this problem. However, we did not find any study that document patient reported outcome. OBJECTIVE: the objective of this study was to determine the patients' perspectives of outcome of open reduction in the management of old unreduced elbow dislocation. METHODS: This was a prospective interventional study of 49 consecutive patients with old unreduced simple elbow dislocation who were treated with open reduction at the National Orthopaedic Hospital, Dala - Kano, Nigeria and Albarka Clinic Kano, Nigeria between January 2015 and December 2019. RESULTS: Fourty nine patients were studied with median age of 31.0 years (range: 19-60 years). The majority of the patients were within 31-40 years age group. The male to female ratio was 6:1. Using the Mayor Elbow Performance Scale (MEPS) and Patients specific Functional scale (PSFS); there are significant improvements in postoperative functional capability of the patients (P = 0.000). With the short assessment for patient satisfaction (SAPS), 93.3% of patients were either satisfied or very satisfied with the outcome of open reduction. CONCLUSION: The outcome of open reduction for old unreduced elbow dislocation is good and is well accepted by the patients.

Implementation of multidrug-resistant tuberculosis (MDR-TB) treatment in Gabon: lessons learnt from the field.

PURPOSE: Since May 2016, WHO recommended a 9-12 month short-treatment regimen for multidrug-resistant tuberculosis (MDR-TB) treatment known as the 'Bangladesh Regimen'. However, limited data exist on the appropriateness thereof, and its implementation in low- and middle-income countries (LMIC). We report here on the pilot phase of the evaluation of the Bangladesh regimen in Gabon, prior to its endorsement by the WHO. METHODS: This ongoing observational study started in September 2015. Intensive training of hospital health workers as well as community information and education were conducted. GeneXpert-confirmed MDR-TB patients received the second-line anti-tuberculosis drugs (4KmMfxPtoHCfzEZ/5MfxCfzEZ). Sputum smears and cultures were done monthly. Adverse events were monitored daily. RESULTS: Eleven patients have been treated for MDR-TB piloting the short regimen. All were HIV-negative and presented in poor health with extensive pulmonary lesions. The overall sputum culture conversion rate was 64% after 4 months of treatment. Three patients developed marked hearing loss; one a transient cutaneous rash. Of 11 patients in our continuous care, 7 (63.6%) significantly improved clinically and bacteriologically. One (9.1%) patient experienced a treatment failure, two (18.2%) died, and one (9.1%) was lost to follow up. CONCLUSIONS: Our pioneering data on systematic MDR-TB treatment in Gabon, with currently almost total absence of resistance against the second-line drugs, demonstrate that a 9-month regimen has the capacity to facilitate early culture negativity and sustained clinical improvement. Close adverse events monitoring and continuous care are vital to success.

Effects of Unripe Musa Paradisiaca on the Histochemistry of the Testis and Testosterone Levels in Adult Albino Rats.

This study was aimed at determining the effects of the unripe fruit of Musa paradisiaca on the testis andtestosterone levels in male Wistar rats. The animals were grouped into three, comprising a control, and 2 treatment groupsadministered with different doses (500 mg/kg and 1000 mg/kg) daily of the fruit flour over 28 days. Histochemical evaluationof the testes was done using Haematoxylin and Eosin, Periodic acid Schiff's (PAS) and Feulgen staining techniques, whilethe serum and homogenised testicular tissue were evaluated for testosterone levels using Accu-Bind ELISA Kit. The testisof the treated groups showed more rapidly dividing cells and more population of sperm cells compared to the control group,and also showed more positivity for Feulgen staining and PAS reaction. Both serum and testicular testosterone levels werehowever reduced. Serum testosterone was significantly lowered in the animals given the low dose (0.67 ± 0.03 ng/ml),compared to those given high dose (0.85 ± 0.02 ng/ml) and the control animals (1.88 ± 0.15 ng/ml) (p < 0.05). Changes intesticular testosterone were not statistically significant. The study suggests that M. paradisiaca fruit has reproductiveenhancing potential when consumed moderately, but this benefit may not be related to testosterone levels.

Genetic damage induced by electronic waste leachates and contaminated underground water in two prokaryotic systems.

The inappropriate and unsafe management practices related to disposal and recycling of electronic wastes in Nigeria has led to environmental and underground water contamination. Reports on the level and type of contamination as well as the possible DNA damage effects of this contamination are insufficient. This study evaluated the DNA damaging potential of e-waste simulated and raw leachates, and its contaminated underground water using the SOS chromotest on Escherichia coli PQ37 and the Ames Salmonella fluctuation test on Salmonella typhimurium strains TA98 and TA100, without and with metabolic activation. Physico-chemical parameters of the samples were also analyzed. The result of the Ames test showed induction of base pair substitution and frameshift mutation by the test samples. However, the TA100 was the more responsive strain for the three samples in terms of mutagenic index in the absence and presence of metabolic activation. The SOS chromotest results were in agreement with those of the Ames Salmonella fluctuation test. Nevertheless, the E. coli PQ37 system was slightly more sensitive than the Salmonella assay for detecting genotoxins in the tested samples. Lead, cadmium, manganese, copper, nickel, chromium, arsenic, and zinc contents analyzed in the samples were believed to play a significant role in the observed DNA damage in the microbial assays. The results of this study showed that e-waste simulated and raw leachates, and its contaminated underground water are of potential mutagenic and genotoxic risks to the exposed human populace.

Low incidence of the immune reconstitution inflammatory syndrome among HIV-infected patients starting antiretroviral therapy in Gabon: a prospective cohort study.

There is a paucity of data on the immune reconstitution inflammatory syndrome (IRIS) in the Central African region. We followed ART-naive HIV-infected patients initiating antiretroviral therapy in an HIV clinic in Gabon, for 6 months. Among 101 patients, IRIS was diagnosed in five. All IRIS cases were mucocutaneous manifestations. There were no cases of tuberculosis (TB) IRIS, but active TB (n = 20) was associated with developing other forms of IRIS (p = 0.02). Six patients died. The incidence of IRIS is low in Gabon, with mild, mucocutaneous manifestations.

Estimation of staute from toe lengths: an evaluation of the Hausa population in Nigeria using linear modeling

Background: Statue determination has remained a basic requirement in determining human identity and ethnicity. Usually in situations when whole anatomical structures are unavailable, forensic expert would be expected to rely on smaller structures such as the phalanges, patella ribs and other fragmentary bones. Aim: The present study evaluates toe anthropometry and its usability as predictors of the stature of the Hausa ethnic group in Nigeria. Methods: Six hundred and sixty four (664) subjects comprising of equal percentage of adult males and females were included in the study group. Toe lengths of both feet (coded as big toe or first toe [1T] to the fifth toes [5T]) were measured using a digital Vernier calliper with accuracy of 0.01mm while stature was taken using a stadiometer with accuracy of 0.1m. SPSS (IBM®) t-test was to evaluate gender difference in the measured dimensions; while SPSS and XLSTAT (2015) Automatic & Generalized Linear Modelling were used to determine the predictability of stature from the toe lengths. The significance level was set at 95% as P ≤ 0.05 was considered significant. Results: The automatic (multiple) regression analysis showed that the males displayed significantly higher mean values than the females for all measured parameters (P<0.001). The general population regression formulae were derived and only three (3) variables (R2T, R5T and L3T) significant contributors to the models for stature prediction for the general Gp (R2=0.385, F[3, 660]=137.68, P<0.001) and female F (R2=0.137, F[3, 328]=17.367, P<0.001) population, while only the L.1T could predict male M stature (R2=0.139, F[1, 330] = 54.489, P<0.001). Single regression gender-specific formulae were derived for the measurements that provided significant R2 values. Conclusion: This study suggested that estimation of a stature of Hausa ethnic group could be made possible by using specific toe measurements. However, lengths of toe may not be so reliable in the estimation of stature, but could be used for sex discrimination in forensic investigation

Molecular epidemiology of Staphylococcus aureus from Lambaréné, Gabon.

While there is an abundance of data on the epidemiology and molecular typing of Staphylococcus aureus, especially those carrying Panton-Valentine leucocidin (PVL) genes or mecA from Western Europe, Northern America and Australia, comparably few studies target African strains. In this study, we characterised genes associated with virulence and resistance, as well the phylogenetic background of S. aureus from healthy carriers and outpatients in Gabon. In total, 103 isolates from 96 study participants were characterised. Seventy-nine isolates originated from throat swabs and 24 isolates from skin lesions. Three isolates carried mecA, although only one, belonging to CC8-MRSA-IV [PVL+] 'USA300', was found to be phenotypically oxacillin-resistant; two CC88-MRSA-IV isolates appeared to be oxacillin-susceptible. PVL genes were common, with a total of 44 isolates (43 %) found to be PVL-positive. CC15-MSSA [PVL+] (n = 29) and CC152-MSSA [PVL+] (n = 9) were the predominant clones among the PVL-positive isolates. Among PVL-negative isolates, CC5-MSSA (n = 12), CC101-MSSA (n = 10) and CC15 (n = 9) were the most frequent. A hitherto undescribed multilocus sequence type of S. schweitzeri was detected twice in unrelated patients. The data emphasise a need for further studies on the role of PVL in African populations and the clinical significance of S. schweitzeri.

Mutagenicity of automobile workshop soil leachate and tobacco industry wastewater using the Ames Salmonella fluctuation and the SOS chromotests.

Environmental management of industrial solid wastes and wastewater is an important economic and environmental health problem globally. This study evaluated the mutagenic potential of automobile workshop soil-simulated leachate and tobacco wastewater using the SOS chromotest on Escherichia coli PQ37 and the Ames Salmonella fluctuation test on Salmonella typhimurium strains TA98 and TA100 without metabolic activation. Physicochemical parameters of the samples were also analyzed. The result of the Ames test showed mutagenicity of the test samples. However, the TA100 was the more responsive strain for both the simulated leachate and tobacco wastewater in terms of mutagenic index in the absence of metabolic activation. The SOS chromotest results were in agreement with those of the Ames Salmonella fluctuation test. Nevertheless, the E. coli PQ37 system was slightly more sensitive than the Salmonella assay for detecting genotoxins in the tested samples. Iron, cadmium, manganese, copper, nickel, chromium, arsenic, zinc, and lead contents analyzed in the samples were believed to play significant role in the observed mutagenicity in the microbial assays. The results of this study showed that the simulated leachate and tobacco wastewater showed strong indication of a genotoxic risk. Further studies would be required in the analytical field in order to identify and quantify other compounds not analyzed for in this study, some of which could be responsible for the observed genotoxicity. This will be necessary in order to identify the sources of toxicants and thus to take preventive and/or curative measures to limit the toxicity of these types of wastes.

Pattern of prostate cancer among a Nigerian population: A study in a single tertiary care centre.

Background: Prostate cancer has become a global health challenge because of its rising morbidity and mortality in males. It is the second cause of cancer death following lung cancer in men. It is rare under the age of 40 and its incidence has been shown to increase exponentially with age. Previously, Prostate cancer was thought to be a disease rare in blacks owing to the fact that not so much was known of the disease. Aims and Objectives: The objective of the study was to review the prevalence, pattern of presentation and clinic-pathologic findings of prostate cancer in the Department of Radiotherapy, Lagos University Teaching Hospital (LUTH), between January 2001 to December 2010 in comparison to previous and recent studies globally. Methodology: Data collection for all patients histologically diagnosed with Prostate cancer at the Department of Radiotherapy, LUTH, from 1st of January 2001 to 31st of December 2010 was done. Results: A total of 144 cases with histologically confirmed Prostate cancer seen during the ten year study were analysed. The highest frequency was seen in the year 2010 with 34 cases. The age range was 41 to 81years with a mean of 66.19 ±7.30years.Adenocarcinoma was the commonest histological type with 98.6%.9(6.3%) patients had a positive family history of prostate cancer out of which 3(33.3%) had their brother affected the malignancy. 51(35.4%) patients presented with stage IV disease.18(12.5%) patients had a Gleason's score of 6,10(6.9%) patients had a Gleason's score of 7 and 2(1.4%) patients had a Gleason's score of 10. The most common presenting complaints were bone pains seen in 51(35.4%) patients, frequent night urine and difficulty with micturition seen in 50(34.7%) and 42(29.2%) patients respectively. Conclusion: This study showed that prostate cancer is not as rare as it used to be. Reasons attributed to its rarity then were lack of awareness, poor screening facilities and poor diagnosing technique.

Bioactive constituents and antibacterial screening of two nigerian plant extracts against selected clinical bacteria

Background: The growing desires to combat antibiotic resistance among pathogenic bacteria necessitate the need to search for new antimicrobials agents from other sources such as plants.Objectives: The present study investigated the antibacterial activities and bioactive components of Nymphaea lotus and Spondias mombin against selected clinical bacteria.Material and Methods: Extracts of N. lotus and S. mombin were prepared by 72 hours maceration in 70% methanol. The antimicrobial susceptibility testing (AST) of Escherichia coli, Klebsiella pneumoniae, Enterobacter aerogenes, Salmonella typhi, Staphylococcus aureus, Citrobacter freundi and, Klebsiella oxytoca against the two extracts was carried out by disk diffusion method while minimum inhibitory concentrations (MIC) and minimum bactericidal concentrations (MBC) was by agar-well dilution and broth dilution method, respectively. The bioactive compounds of the plants were identified by Gas Chromatography-Mass Spectrometry (GC-MS) analysis.Results: Extracts of N. lotus showed better antimicrobial activities than S. mombin against all the clinical bacterial isolates with an MIC range of 3.13 ­ >12.5mg/mL compared to S. mombin with MIC range of 6.25 ­ >12.5mg/mL. The GC-MS results revealed the presence of 21 and 25 compounds for N. lotus and S. mombin respectively. Benzoic acid derivatives were in abundance in both plants with approximately 71.5% and 82.1% in N. lotus and S. mombin respectively.Conclusions: The findings from this study provided further evidence on their ethno-botanical claims and additional information on the potentials of the studied plants as effective medicinal plants with antimicrobial activity against clinical bacteria. This highlights the need for continuous exploration of medicinal plants for novel compounds with better antimicrobial property as option for the treatment of resistant bacterial infection

A Cross-sectional Survey of the Willingness of Tertiary Hospital Staff to Donate Blood in Sagamu, Nigeria

Background: Available donor blood rarely meets the demand in sub-Saharan Africa due to obstacles to blood donation. Willingness to donate blood is adjudged an important step to the actual practice of donating blood.Objective: To assess the willingness of the members of staff of the hospital to donate blood and determine factors affecting their willingness or otherwise.Methods: This was a descriptive cross-sectional study. A proportional allocation of participants was carried out at the various departments in the hospital using self-administered questionnaire. Results: Overall, 183 (73%) of the 246 respondents expressed willingness to donate blood, 111(45%) of whom have been asked to donate blood in the past. Only 91(37%) had donated blood in the past. Significantly higher proportion of health staff showed the willingness to donate blood generally and voluntarily compared to non-health staff. Significantly higher proportion of respondents with tertiary education showed the willingness to donate blood. Two hundred and eighteen (88.8%) were willing to donate blood to help the patient in need while fear of exposure to HIV infection, needle prick and dizziness constituted the major factors discouraging blood donation (19.9%, 18.7% and 18.3% respectively.Conclusion: Willingness to donate blood was mostly based on the primordial motivation of helping the patient in need which does not translate to blood donation. There is a need to improve awareness and advocacy on blood donation among hospital staff and the general population

Incidence of Hydronephrosis in Cervical Cancer Patients in A Tertiary Hospital Lagog, Nigeria.

BACKGROUND: Cervical cancer is still a global health challenge that affects women of reproductive age group and consequently causes a drawback on the social and economic stability of nations. Developing countries suffer a greater burden of the disease because of several factors such as poverty, multiple sexual partners, unbalanced diet, poor knowledge and attitude to prevention of diseases and late-presentation. OBJECTIVE: The aim of this study is to evaluate the incidence of hydronephrosis in cervical cancer patients in Lagos University Teaching Hospital (LUTH), Lagos, Nigeria for the period of 3 years (2010-2012). METHOD: This study is a cross sectional study carried out among cervical cancer patients seeking treatment in the Radiotherapy department of the Lagos University Teaching Hospital (LUTH), between the year 2010 and 2012, to find out the incidence of hydronephrosis using abdominopelvic ultrasonography. RESULTS: The incidence of hydronephrosis during the 3years period studied was 43.7%. A rise in the incidence of hydronephrosis of 5.4% in 2011 and 13.3% in 2012 was noted. The mean age of the patients was 55.5 years. 122 (56.7%) were grand multiparous and 123 (57.2%) had multiple sexual partners. An increase of 8.3% in 2011 and 9.3% in 2012 was noted in the incidence of cervical cancer cases studied. 107 (49.8%) presented at stages III and IV. CONCLUSION: Late presentation of patients is still a major challenge affecting treatment outcomes. The presence of hydronephrosis was noticed at staging, during or after treatment, resulting in the need to separate this population from current Stage IIIB classification. The presence of hydronephrosis may or may not be related to the disease and so adequate staging is important.

Nucleus drop during small incision cataract surgery: A report of four cases.

Small incision cataract surgery (SICS) offers the benefits of a phacoemulsification (phaco) surgery without the attendant high cost, but it is not without certain risk such as nucleus drop into the vitreous as seen in phaco. A retrospective study of SICS and associated factors leading to nucleus drop during surgery, challenges of management and the visual outcomes. Of 793 eye surgeries performed during the study 586 were SICSs. Nucleus drop during SICS occurred in 0.68% of patients. Can-opener technique of capsulotomy, use of dispersive viscoelastic, diabetes mellitus, lack of anterior vitrectomy machine and poor access to immediate posterior vitrectomy were important problems in the management of the cases of nucleus drop in this study. The visual outcomes were poor in all the cases of nucleus drop. Careful patient selection for SICS and the use of continuous curvilinear capsulorhexis are advocated. An interior vitrectomy machine should be available to all cataract surgeons. It is good professional practice to be acquainted with the available vitreo-retina surgeons for urgent assistance in cases of nucleus drop.
