ABSTRACT

Background: The quinolone group, a synthetic antimicrobial, is widely used worldwide to treat many diseases, including those caused by Gram-negative bacteria. Escherichia coli and others are among the bacteria that produce quinolone resistance genes (qnr) such as qnrA and aac(6?)-Ib-cr. Objective: The present study aimed to the isolate Escherichia coli from patients attending some Hospitals in Wad Medani city, identification of drug resistance patterns and detection of the frequency of quinolones resistance genes; qnrA and aac(6?)-Ib-cr among isolated strains. Methods: A cross-sectional descriptive, hospital-based study included 119 Escherichia coli strains was conducted. A designed questionnaire used for demographic data collection and the attitude toward antimicrobials usage. Clinical specimens were processed for aerobic bacterial isolation and identification. Antimicrobial sensitivity performed by Kirby Bauer disc diffusion technique according to the CLSI guidelines. Presence of qnrA and aac(6?)-Ib-cr genes was assessed by multiplex PCR. Results: Most strains of Escherichia coli originated from urine 53.8% (64/119) and wounds 42.9% (51/119) specimens. Meropenem had the best effect against tested strains with susceptibility of 85% (101/119). Multiplex PCR assay, using specific primers, demonstrated that 41.2% (49/119) and 37.8% (45/119) of isolated Escherichia coli possessed qnrA and aac(6?)-Ib-cr genes respectively. Conclusion: The high rate of qnrA and aac (6)-Ib-cr genes among Escherichia coli necessitate the usage of molecular tools in detecting the genetic determinants of drug resistance microorganisms in countries such as Sudan.

ABSTRACT

L'hypertension artérielle maligne (HTAM) est un problème de santé publique en Afrique subsaharienne. L'objectif de cette étude était de décrire le profil épidémio-clinique et les facteurs pronostiques de l'HTAM à Fousseyni DAOU de Kayes. Méthodes. Nous avons réalisé une étude rétrospective et descriptive du 1er janvier 2016 au 31 juin 2022 à l'unité de néphrologie de l'hôpital Fousseyni Daou de Kayes. Étaient inclus, les patients hypertendus ou normotendus sous traitement hospitalisés avec une rétinopathie hypertensive (RH) de stade II ou III (selon la classification de Kirkendall) associée à une ou plusieurs autres atteintes viscérales et ayant un dossier médical complet. Résultats. Au total 117 cas d'HTAM ont été enregistrés sur 7011 dossiers examinés, dont 53,8% d'hommes (63 cas). L'âge moyen était de 39,47 ans. La moyenne de la pression artérielle à l'admission était de 187/114 mmHg. La RH était de stade II et III dans 59,8% et 40,2% des cas. L'insuffisance rénale était retrouvée chez 93,1% des patients (109 cas) dont 63,7% d'insuffisance rénale chronique (IRC) contre 36,7% d'insuffisance rénale aiguë (IRA). L'hypertrophie ventriculaire gauche a été retrouvée dans 80,4% des cas. L'issue globale des patients a été favorable dans 59% (69 cas) contre 31,6% (37 cas) de décès et 9,4% (11 cas) de sortie contre avis médical. Les facteurs associés au risque de décès étaient surtout la RH stade III, la dyslipidémie, l'IRC terminale et l'hyponatrémie. Conclusion. L'HTAM reste un problème de santé publique au Mali et touche préférentiellement les sujets jeunes avec une morbi mortalité élevée

ABSTRACT

This study investigated the probiotic potentials of seven lactic acid bacteria (LAB) strains at different temperatures, pH, and bile salt concentrations. Their antimicrobial activity and antibiotic susceptibility were also determined. There were significant (P˂0.05) differences in the LAB growth at 45-650C with viable counts ranging from 4.28-8.34 Log10 Cfu/ml after 48 h. The LAB strains showed significant (P˂0.05) increase at pH 2, 2.5 and 3 after 3 and 6 h. L. parabuchneri LMG was viable at 45 and 65oC with 99.30 and 65.00% survival respectively. The LAB showed high resistance to 0.3% bile salt at 97.90%. L. plantarum CIP was viable with 95.40% survival at pH 3.0 after 3 h. All the LAB strains were susceptible to cefuroxime (20 µg/ml) and erythromycin (10 µg/ml) at 13.00-45.00 mm zone of inhibition (ZOI). They had strong antimicrobial activity against Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 9027 and Listeria monocytogenes ATCC 15313. Leuconostoc mesenteroides LM and L. brevis ATCC inhibited the five tested food borne pathogens with ZOI varying from 8.00-26.00 mm. The results from this study showed that the LAB strains isolated from fermented foods had probiotic potential and can be used for research and commercial purposes.

ABSTRACT

The Government of India initiated the COVID-19 vaccination for children in the age group of 15 -18 years on January 3 rd 2022. Although this was a much-awaited phase of vaccination, the parents, health care workers and the organizations dispensing the vaccines had many doubts and concerns regarding consent and liability for adverse effects, especially in this age group. There are no clear cut guidelines issued by the Ministry of Health & Family Welfare, Government of India on this subject. In this article, we elaborate on the various aspects of consent, particularly consent for vaccination, which is being followed in our country. By analyzing the related sections in the Indian Penal Code and prevalent practices in our country regarding consent, we endeavour to answer frequently encountered questions.

ABSTRACT

@#The NS2B/NS3 protease is crucial for the pathogenesis of the DENV. Therefore, the inhibition of this protease is considered to be the key strategy for the development of new antiviral drugs. In the present study, malabaricones C (3) and E (4), acylphenols from the fruits of Myristica cinnamomea King, have been respectively identified as moderate (27.33 ± 5.45 μM) and potent (7.55 ± 1.64 μM) DENV-2 NS2B/NS3 protease inhibitors, thus making this the first report on the DENV-2 NS2B/NS3 protease inhibitory activity of acylphenols. Based on the molecular docking studies, compounds 3 and 4 both have π-π interactions with Tyr161. While compound 3 has hydrogen bonding interactions with Gly151, Gly153 and Tyr161, compound 4 however, forms hydrogen bonds with Ser135, Asp129, Phe130 and Ile86 instead. The results from the present study suggests that malabaricones C (3) and E (4) could be employed as lead compounds for the development of new dengue antivirals from natural origin.

ABSTRACT

@#The severe acute respiratory syndrome coronavirus 2 is a novel coronavirus that causes the coronavirus disease 2019 (COVID-19). COVID-19 has been declared a pandemic by the World Health Organisation since March 2020. To date, the number of confirmed COVID-19 cases has exceeded 47 million and more than 1.2 million people have lost their lives to the disease. The disease is spreading at an exponential rate with no signs of slowing down. COVID-19 testing and early diagnosis play a crucial role in not just patient management, but also the prevention of the further spread of the disease. Various diagnostic approaches have been applied to detect SARS-CoV-2 infection. This article will critically review these diagnostic approaches and compare each with the gold-standard, which is viral RNA detection using reverse transcriptase-polymerase chain reaction (RT-PCR).

ABSTRACT

OBJECTIVES: To prospectively evaluate demographic, anthropometric and health-related quality of life (HRQoL) in pediatric patients with laboratory-confirmed coronavirus disease 2019 (COVID-19) METHODS: This was a longitudinal observational study of surviving pediatric post-COVID-19 patients (n=53) and pediatric subjects without laboratory-confirmed COVID-19 included as controls (n=52) was performed. RESULTS: The median duration between COVID-19 diagnosis (n=53) and follow-up was 4.4 months (0.8-10.7). Twenty-three of 53 (43%) patients reported at least one persistent symptom at the longitudinal follow-up visit and 12/53 (23%) had long COVID-19, with at least one symptom lasting for >12 weeks. The most frequently reported symptoms at the longitudinal follow-up visit were headache (19%), severe recurrent headache (9%), tiredness (9%), dyspnea (8%), and concentration difficulty (4%). At the longitudinal follow-up visit, the frequencies of anemia (11% versus 0%, p=0.030), lymphopenia (42% versus 18%, p=0.020), C-reactive protein level of >30 mg/L (35% versus 0%, p=0.0001), and D-dimer level of >1000 ng/mL (43% versus 6%, p=0.0004) significantly reduced compared with baseline values. Chest X-ray abnormalities (11% versus 2%, p=0.178) and cardiac alterations on echocardiogram (33% versus 22%, p=0.462) were similar at both visits. Comparison of characteristic data between patients with COVID-19 at the longitudinal follow-up visit and controls showed similar age (p=0.962), proportion of male sex (p=0.907), ethnicity (p=0.566), family minimum monthly wage (p=0.664), body mass index (p=0.601), and pediatric pre-existing chronic conditions (p=1.000). The Pediatric Quality of Live Inventory 4.0 scores, median physical score (69 [0-100] versus 81 [34-100], p=0.012), and school score (60 [15-100] versus 70 [15-95], p=0.028) were significantly lower in pediatric patients with COVID-19 at the longitudinal follow-up visit than in controls. CONCLUSIONS: Pediatric patients with COVID-19 showed a longitudinal impact on HRQoL parameters, particularly in physical/school domains, reinforcing the need for a prospective multidisciplinary approach for these patients. These data highlight the importance of closer monitoring of children and adolescents by the clinical team after COVID-19.

ABSTRACT

INTRODUCTION@#Limited data are available on the incidence of primary ophthalmic cancers worldwide. We describe the incidence and trends of primary ophthalmic cancers in Singapore.@*METHODS@#Data on ophthalmic cancers diagnosed in Singapore from 1996 to 2016 were retrieved from the Singapore Cancer Registry for analysis. All were histologically proven primary ophthalmic cancers. Calculations of incidence and age-specific frequency of ophthalmic malignancy were made.@*RESULTS@#A total of 297 cases were included, with males constituting 59.9%. The race distribution was 78.5% Chinese, 16.5% Malay, 3.7% Indians and 1.3% others. There was an overall increase in ophthalmic malignancies. The mean age of onset was 47.4 years. The most common cancers were retinoblastoma (93.3%) in patients younger than 15 years, and lymphoma (71.3%) in patients aged 15 years and older. There has been an increase in lymphomas from 16.7% in 1968-1995 to 71.3% in 1996-2016 in those aged 15 years and older. The most common types of ophthalmic cancer according to location are lymphoma of the orbit, conjunctiva, cornea and lacrimal gland; retinoblastoma of the retina; and malignant melanoma of the choroid and ciliary body.@*CONCLUSION@#Our study reported the incidence and trends of ophthalmic cancer in the Singapore population and showed an overall increase in ophthalmic malignancies in Singapore from 1996-2016. A substantial increase in lymphomas over the last 2 decades was noted. The data could aid clinicians, epidemiologists and policymakers in implementing strategies to address trends in ophthalmic cancers and spur aetiological research to improve quality of life in patients with such cancers.

ABSTRACT

INTRODUCTION@#Globally, cervical cancer is the fourth most common cancer in women, with about 85% occurring in low-middle income countries (LMIC) and an age-standardised incidence rate of more than 15 per 100,000. It is largely preventable through HPV vaccination and cervical cancer screening. In Singapore, 18% of the foreign domestic workforce hail from Indonesia, the Philippines, Myanmar, and India. However, there is no data on preinvasive cervical disease and cervical cancer in foreign domestic workers (FDWs) and the aim of this pilot programme is to determine the baseline screen positive rate of high-grade intraepithelial in this population.@*METHODS@#A total of 322 FDWs were offered HPV screening through the Helping Our Helper (HOH) pilot programme. Data from this pilot programme were analysed and reported using simple descriptive statistics.@*RESULTS@#Out of the 322 FDWs who registered for HPV screening, 68.6% participated. There was a 22.2% screen-positive rate; 10% of those who screened positive for high-risk HPV had histologically confirmed high-grade cervical intraepithelial neoplasia. This result is similar to other data on cervical cancer screening in Singaporeans. This pilot project screened less than 1% of the eligible FDWs in Singapore.@*DISCUSSION@#The findings of this pilot programme suggest that there is public health value in providing cervical cancer screening to FDWs. Improving cervical cancer screening by increasing awareness and including routine cervical cancer screening as part of the employment medical examination should be studied.

ABSTRACT

This study is conducted to determine the population density of mosquitoes in three selected area (Kofar Taramniya, Mabera and Bello Way) in Sokoto metropolis. To identified and count the population of mosquito, different breeding sites were investigated for the preferences of mosquitoes. Mosquito larvae were collected using dipper, ladle spoon from drainages, stagnant water, gutters, open wells, local pots, water tanks and cattle sheds. A total population of 4,764 mosquito larvae were collected and identified From the three (3) selected areas larvae and pupae were encounters in abundance. In Mabera area, a total of 1799 (37.7%) larvae are collected in which 1199 (45.8%) belonging to Anophelesgenera and 600 (27.9%) belong to culexgenera. In kofar Taramniya a total of 1649 (34.6%) larvae are collected in which 1000 (38.2%) belong to Anopheles genera and 649 (30.2%) belong to culexgenera, in Bello Way, A total of 1317 (27.5%) larvae were collected,417 (15.9%) belong to Anophelesgenera and 900 (41.9%)belongto culexgenera. Statistical analysis conducted indicated a significant difference (p<0.05) between the three collections. Mosquitoes encountered belong to two genera of Anophelesand Culex. The predominant genus was Anopheleswith a total of 2,615 larvaewhile Culexhas a total of 2149 larvae in all the three study areas. Considering the medical importance of mosquitoes, the information provided from this study will serve as a basis for understanding the implication of mosquitoes nuisance and provide effective control strategies against the vector and to reduce mosquitoes born disease

ABSTRACT

Objective: The objectives of this study include performing pharmaceutical care-related research and documenting regarding drug-related problems in the surgery department. Further, these types of studies may bring consciousness to both physicians and patients regarding drug use in surgery. Methods: A Prospective interventional study was conducted in a general surgery hospital. The prescriptions were analyzed for the use of inappropriateness of drugs using the classification for drug-related problems. Results: Out of 100 cases, 62 patients were observed with drug-related problems. The number of antibiotics prescribed was 0, 1, 2, 3, 4, 5, 6 in 8, 11, 12, 32, 18, 18, 1 cases respectively. A significant increase in the outcome of antibiotic rationality and cases adhered to guidelines was seen in November compared to October and somewhat decreased in December due to some limitations. The overall study states that prescribing has a more important cause of Drug-related problems compared to dispensing and the use of the drug. Conclusion: Drug-related problems have to be acknowledged as a very important contributing treatment factor for the best health care outcome. Our study shows the importance of clinical pharmacists in every hospital for identifying and resolving drug-related problems and medication errors.

ABSTRACT

Aim:This research aimed to determine the relationship between substance use disorder (SUD) and the biomarkers of inflammation: (C-reactive protein: CRP and Interleukin-6: IL-6) to investigate inflammatory reaction among SUD patients. Study Design:This is a cross sectional comparative study. Place and Duration of Study:This study was conducted at Federal Neuro-Psychiatric Hospital (FNPH) Kaduna, North-western Nigeria which serve as a referral center for patients with psychiatric disorders from all the NorthWestern states and the Federal Capital Territory, Abuja between August 2018 and August 2019. Methodology:The study population was drawn from SUD patients who were positive to urine drug test. The serum CRP and IL-6 levels of 180 SUD patients (study group) were compared with the serum CRP and IL-6 levels of 180 apparently normal individuals who do not have history of substance abuse.Results:The median and interquartile range of the ages of both the study group and the control group were 30 (23 –40) and33.5 (24-41) years respectively. The study population consist of 162 (90%) males and 18 (10%) females with median ages and range of 30.5 (15 –72) and 26 (14 –40) years respectively. A significant increase in IL-6 in SUD was observed (P = .0001) but no significant difference observed in CRP at 95% confidence interval (P = .73). It was observed that there was a strong positive relationship between IL-6 and CRP (r = 0.6646); P = .0001) in SUD patients.Conclusion:IL-6 was significantly higher in people with SUD and as CRP levels increases IL-6 increases. This suggests that there is a level of inflammatory reaction in substance use disorder patients. Thus both serum CRP and IL-6 level can be considered as biomarkers of inflammation in patients with SUD.

ABSTRACT

@#The commonest cause of dementia among the elderly population is Alzheimer’s disease (AD). It is a health concern globally as the number of people affected by dementia worldwide is rapidly increasing. Several genes have been linked to AD and the pathogenesis of the disease has been extensively and vigorously examined. Thus far, only a few drugs have been approved by the Food and Drug Administration (FDA) for the pharmacological treatment of AD and a growing body of research has turned to alternative options such as stem cell therapy. This review will give an overview of the pathological and clinical aspects of AD. Although researchers have explored the suitability and feasibility of using various types of stems cells to treat AD, this review will focus mainly on neural stem cells (NSCs)/ neural progenitor cells (NPCs). The behaviour and properties of NSCs will be described, accompanied by a comprehensive discussion of the therapeutic strategies involving the use of NSCs/NPCs in the treatment of the disease

ABSTRACT

OBJECTIVE@#Obesity has been shown to be associated with adverse outcomes in viral infections such as influenza, but previous studies on coronavirus disease 2019 (COVID-19) had mixed results. The aim of this systematic review is to investigate the relationship between COVID-19 and obesity.@*METHODS@#We performed a systematic review and meta-analysis. A literature search of MEDLINE, EMBASE, Scopus, Web of Science, CENTRAL, OpenGrey and preprint servers medRxiv and bioRxiv was performed, with no restriction on language or date of publication. Primary outcomes of this study were intensive care unit (ICU) admission or critical disease, severe disease and mortality. Secondary outcome was a positive COVID-19 test. Meta-analysis was performed using OpenMeta-Analyst software, and heterogeneity was tested using Cochran's Q test and I2 statistic. The study protocol was registered on PROSPERO (CRD42020184953).@*RESULTS@#A total of 1,493 articles were identified and 61 studies on 270,241 patients were included. The pooled prevalence of obesity was 27.6% (95% confidence interval [CI] 22.0-33.2) in hospitalised patients. Obesity was not significantly associated with increased ICU admission or critical illness (odds ratio [OR] 1.25, 95% CI 0.99-1.58, @*CONCLUSION@#Obesity increased the risk of severe disease, mortality and infection with COVID-19. Higher body mass index was associated with ICU admission and critical disease. Patients who are obese may be more susceptible to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, and infected patients should be monitored closely for adverse outcomes.

ABSTRACT

Background: Diabetes Mellitus (DM) is a major emerging health issue and the risk factors are varied in women making them susceptible to it. Metformin is most preferred and widely used drug worldwide due to various reasons. Vitamin B12 deficiency in DM caused by Metformin is least known side effect. Objective: This study was taken up to assess the correlation between deficiency and duration and dose of metformin treatment. Methods: This being a hospital based observational study, 650 Diabetic women were evaluated by detailed questionnaire, general physical examination, fasting blood glucose (FBS), post prandial blood glucose (PPBS), serum Vitamin B12 levels, CBC and NCS. Results: The mean age of the cases was 51.98±5.17years. 164/408 cases (on metformin therapy for >3 months) had low vitamin B12 as against 22/242 controls (never on metformin therapy). Mean Serum vitamin B12 was low in cases with less duration of DM when compared to cases with longer duration. Vitamin B12 deficiency was correlated with anemia and neuropathy. Conclusions: Metformin treatment in cases is associated with higher prevalence of Vitamin B12 deficiency which increases with duration of DM and dose of metformin. Deficiency correlated with development of macrocytic anemia and worsening of neuropathy. In some, symptoms of deficiency are difficult to diagnose and can be irreversible if left untreated (like neuropathy). Routine screening of Vitamin B12 levels, CBC, NCS should be done in all diabetic women at the beginning of metformin therapy, and yearly thereafter. Treatment and prevention of deficiency is easy, cheap, safe, and effective.

ABSTRACT

Background: Methicillin-resistant Staphylococcus aureus (MRSA) are a major cause of hospital- and community-acquired infection. They can colonize humans and cause a wide range of infections including pneumonia, endocarditis and bacteraemia. We investigated the molecular mechanism of resistance and virulence of MRSA isolates from a teaching hospital in Ghana. Methodology: A total of 91 S. aureus isolates constituted the initial bacterial sample. Identification of S. aureus was confirmed by the VITEK 2 system. The cefoxitin screen test was used to detect MRSA and antibiotic susceptibility was determined using the VITEK 2 system. The resistance (mecA, blaZ, aac-aph, ermC, and tetK) and virulence (lukS/F-PV, hla, hld and eta) genes were amplified by polymerase chain reaction (PCR) and positive samples subjected to DNA sequencing. Pulsed field gel electrophoresis (PFGE) was used to ascertain the relatedness of the isolates. Results: Fifty-eight of 91 (63.7%) isolates were putatively methicillin resistant by the phenotypic cefoxitin screen test and oxacillin MICs. However, 43 (47%) of the isolates were genotypically confirmed as MRSA based on PCR detection of the mecA gene. Furthermore, 37.9% of isolates displayed resistance to tetracycline, 19% to trimethoprim-sulphamethoxazole, 15.5% to clindamycin, 12.1% to gentamicin, 13.8% to ciprofloxacin and erythromycin, 6.9% to moxifloxacin and 7.0% to rifampicin. None of the isolates was positive for inducible clindamycin resistance. The prevalence of resistance (mecA, blaZ, aac(6')-aph(2''), tetK, and ermC) and virulence (hla and lukS/F-PV) genes respectively were 74%, 33%, 22%, 19%, 3%, 5% and 3%, with isolates organized in two highly related clades. Conclusion: Results indicate a fairly high occurrence of MRSA, which can complicate the effective therapy of S. aureus infections, necessitating surveillance and stringent infection control programmes to forestall its spread
