ABSTRACT

CONTEXT: Testis-specific protein Y-encoded-like 5 (TSPYL5) suppresses several cancers in vivo, including colorectal cancer (CRC); however, its mechanism and role in CRC cell tumorigenesis in vivo remain unknown.

AIMS: To elucidate the molecular mechanisms of colorectal cancer and find new therapeutic targets to improve CRC patient outcomes.

SETTINGS AND DESIGN: Male mice (4 weeks old, 16-22 g) were housed in sterile cages in a temperature-controlled room (20-25°C) with a 12 h light/dark cycle and ad libitum food and water.

METHODS AND MATERIALS: TSPYL5 overexpressing or non-overexpressing HCT116 cells were used to create a nude mouse tumor model. Tumor tissue was evaluated histologically after hematoxylin and eosin (H and E) staining. TUNEL staining assessed tumor cell apoptosis. Ki67 expression in excised tumor tissue was measured by immunohistochemistry. Western blotting examined double-stranded break (DBS)-associated protein expression in vivo.

STATISTICAL ANALYSIS USED: IBM SPSS Statistics for Windows, Version 21.0 was used for all analyses (IBM Corp., Armonk, NY, USA). At least three independent experiments yield a mean value ± standard deviation. Unpaired Student’s t-tests compared groups. One-way analysis of variance and Dunnett’s test were used to compare groups with a P value < 0.5.

RESULTS: TSPYL5 overexpression inhibited CRC cell tumorigenicity and damaged tumor cells in vivo. TSPYL5 overexpression also significantly increased Bax and p-H2AX (early double-stranded break indicators) and decreased Ki67, Bcl-2, and peroxisome proliferator-activated receptor expression.

CONCLUSIONS: Collectively, TSPYL5 overexpression inhibited the tumorigenicity of CRC cells in vivo by inducing DNA damage.

ABSTRACT

BACKGROUND: This study aimed to detect the impact of politics, security and health on the escalation of road traffic accidents (RTAs) and their consequences in Iraq for the period 2015-2020.

METHODOLOGY: The data of this cross-sectional study were obtained from the annual reports of RTA statistics from the Central Statistical Organisation of the Iraqi Ministry of Planning. The statistical analysis of data was done using the Statistical Package for the Social Sciences.

RESULTS: In this study, it was noted that the rate of RTAs, injuries and deaths increased from 16% to 19.5%, from 16.5% to 17.3% and from 16.2% to 20%, respectively, for the years 2015-2019, while the rates of RTAs, injuries and deaths in 2020 recorded a clear decrease compared to the rest of the years under study, and the rates were as follows: 14.8%, 14.4% and 14.1%, respectively. According to the types of traffic accidents, the rate of crashes recorded the highest rate of 51% in all years of the study compared to the run over, overturn and other unclassified accidents, which were 37%, 10% and 2%, respectively, and it was revealed that crashes, run over and other unclassified incidents increased from 5% to 20%, from 17% to 19% and from 18% to 26%, respectively, for the years 2015-2019, whereas all types of RTAs in 2020 were recorded the lowest rates compared to other years under study. Al-Basra, Baghdad, Al-Najaf and Babylon were recorded the highest rates of traffic accidents for the 6 years under study, with a rate of 13.3%, 11.7%, 11.1% and 10.4%, respectively.

CONCLUSIONS: Although traffic accidents were not recorded in the years 2015, 2016 and 2017 for the governorates of Nineveh and Anbar due to the occupation of the terrorist Islamic State, traffic accidents maintained their levels due to internal migration. It was also noted that the rate of road accidents was the highest in 2019 compared to the years under study due to the liberation of occupied cities, the return of safety and the return of recording accident data again, while the year 2020 recorded a clear decrease in the rate of road accidents, especially in the first half of it due to the October protests that led to the suspension of all government institutions, universities and schools. The second reason for the decrease in the second half of 2020 is attributed to the lockdown of corona. It seems that the political, security, military and health factors have an effective impact on the traffic reality.

ABSTRACT

BACKGROUND: The long-term use of topical anti-glaucoma medications is often associated with ocular surface toxicity that can affect the patient’s drug compliance and quality of life. This study assessed the effect of these medications, using cytological changes of the conjunctiva and ocular surface symptoms.

MATERIALS AND METHODS: This was a clinic-based, case-control study that was conducted at the Lagos University Teaching Hospital that compared glaucoma patients on topical medications with age-sex-matched controls. The controls were non-glaucoma patients, who were not on any topical ocular medications at least 6 months prior to the study. The Ocular Surface Disease Index (OSDI) questionnaire was used to assess ocular surface symptoms. Schirmer’s I test, tear film break-up time (TBUT) test and corneal fluorescein staining of the ocular surface were used for ocular surface disease (OSD) assessment and conjunctival impression cytology (CIC) for histological assessment and grading.

RESULTS: Six hundred and ninety-six eyes of 348 respondents, 174 cases and 174 controls, were assessed for OSD. The mean ages of the case and control groups were 56.3 ± 12.9 years and 55.5 ± 13.2 years, respectively, with no statistical difference (P = 0.589). All ocular parameters assessed were significantly abnormal in the case group compared to the control group. The use of topical anti-glaucoma medications was significantly associated with abnormal TBUT (P < 0.001), Schirmer’s test (P < 0.001), ocular surface staining (P < 0.001), CIC (P < 0.001) and OSDI scores (P = 0.001). A significant association was seen between abnormal TBUT and the number of medications (P = 0.044, odds ratio [OR] =0.79, 95% confidence interval [CI]: 0.44-1.14), between abnormal ocular surface staining and duration of anti-glaucoma medications usage (P = 0.0104, OR = 1.2, 95% CI: 1.04-1.43) and between abnormal CIC and the duration of anti-glaucoma medications (P = 0.0007, OR = 0.7, 95% CI: 0.59-0.86).

CONCLUSION: The study demonstrates that prolonged use of topical anti-glaucoma medications may be associated with damage to the ocular surface structures.

ABSTRACT

CONTEXT: The undiagnosed and untreated tuberculosis (TB) cases underpin the experience of accelerating deaths. Everyone should be engaged in managing TB patients to revert the current trend.

AIMS: In this context, we assessed the outcome of an education intervention on the knowledge of TB and referral practice of presumptive TB cases to directly observed therapy strategy amongst patent medicine vendors (PMVs).

SETTINGS AND DESIGN: The study was quasi-experimental, conducted amongst 647 PMVs in Delta State, Nigeria.

METHODS: A structured questionnaire was administered to obtain baseline data on knowledge of TB. An educational intervention on knowledge of TB was then given. A post-intervention assessment of TB knowledge was subsequently conducted using the same questionnaire. The exact number of referrals of presumptive TB cases by PMVs and the number that tested positive amongst the referred presumptive TB cases, 3 months before and after the training were obtained from the state TB database.

STATISTICAL ANALYSIS USED: SPSS v. 26 was used for data analysis.

RESULTS: The pre-training knowledge average score was 15.45 ± 6.45, while the post-training average score was 19.44 ± 7.03 (P < 0.001). The pre-training average number of presumptive cases referred was 146 ± 124.7, and the post-training was 205.67 ± 255.4, P = 0.41. The pre-training average number of cases that turned out positive was 9.5 ± 6.3, and the post-training was 13.5 ± 11.3, P = 0.42.

CONCLUSION: There was a significant improvement in PMVs’ knowledge of TB post-intervention. However, while an increase in the number of cases referred and positives detected was observed, this was not significant. Periodic training and updates to PMVs in keeping with current trends and best practices in TB management are recommended.

ABSTRACT

BACKGROUND: Health promotion (HP) is a part of the general practitioners’ (GPs) competencies defined by the World Organization of Family Doctors. The implementation of HP in their practice is unsatisfactory.

AIMS: The aim of this study was to explore GPs knowledge, attitudes and practices in Morocco about HP at the primary healthcare services.

METHODS: A cross-sectional study was conducted using an online self-administrated questionnaire including, knowledge, attitudes and practices of GPs toward HP. Descriptive and bivariate analyses were conducted.

RESULTS: Two hundred and forty GPs responded to our questionnaires, the sex ratio was 1.12 with an average age of 40.46 ± 9.05 years. More than half of our participants perceived HP as a concept indistinct from prevention, 70.4% believed that HP refers to the biomedical model. On a Likert scale of 1-5, the level of HP knowledge was 2.71 ± 1.13. The most discussed topics with the population were tobacco, alcohol, overweight and obesity. Statistically significant association was found between the competencies of GPs in lifestyle behaviours and the practice of this competence.

CONCLUSION: The knowledge of GPs remains insufficient, and their practices focus more on the areas in which they feel competent, which requires the implementation of specific training for the development of GPs skills in HP.

ABSTRACT

INTRODUCTION: Varicocele is a treatable aetiology of male infertility. Magnification with surgical loupe has been associated with improved outcome and reduced morbidity than the conventional technique without magnification.

OBJECTIVE: To compare the outcomes of two techniques of subinguinal varicocelectomy, with a surgical loupe and without.

PATIENTS AND METHODS: This was a prospective randomised hospital-based study. Forty-six patients were randomised to two arms – Group A: loupe-assisted subinguinal varicocelectomy (LASV) and Group B: open subinguinal varicocelectomy without Loupe (OSV). They all had their semen and hormonal parameters compared preoperatively and at 3 and 6 months postoperatively. Post-operative complications were also assessed. P < 0.05 was considered statistically significant.

RESULTS: The mean age was 38.28 ± 4.55 years with a range of 27-46 years. The mean age in Group A was 37.35 ± 4.68 and 39.22 ± 4.33 years in Group B. There was an improvement in motility, sperm count and concentration in both the groups at 3 and 6 months (P < 0.05). However, there was no difference in these parameters on comparison of the two groups at 3 and 6 months (P > 0.05). Follicle-stimulating hormone decline was significant in the OSV group at 3 and 6 months, P = 0.010 and 0.021, respectively. There was no difference in other hormonal parameters both at 3 and 6 months (P > 0.05). The pregnancy rate in each arm of study was 4.3%. All complications occurred in Group B.

CONCLUSION: Both techniques resulted in improvement in seminal fluid parameters. All complications occurred in the arm that had subinguinal varicocelectomy without loupe. Loupe-assisted subinguinal varicocelectomy is safe and effective.

ABSTRACT

INTRODUCTION: A newly cut neonatal umbilical stump is a potential portal of pathogen entry leading to omphalitis. Neonatal sepsis can complicate omphalitis, but good cord care practices can reduce this risk.

OBJECTIVE: The objective of this study was to assess umbilical cord care practices in tertiary-, secondary- and primary-level healthcare facilities in Jos, Nigeria.

METHODS: A multi-centre, cross-sectional study of 284 mothers of infants aged 3-6 weeks old attending immunisation clinics in the three-level healthcare facilities using multistage sampling technique between April and September 2019. Data were analysed using SPSS version 23.0. Pearson’s Chi-squared test was used to compare categorical variables. Adjusted odds ratios (AORs) and 95% confidence interval (CI) were used as point and interval estimates, respectively. P < 0.05 was adjudged to be statistically significant.

RESULTS: The mean age of the mothers and infants was 25 ± 6 years and 5 ± 1 week, respectively. Only 2.2% of mothers used chlorhexidine (CHX) gel for cord care. Mothers showed good knowledge but poor practice of cord care. A significant positive relationship was observed between quality of cord care practices and level of healthcare facility (χ² = 15.213; df = 2; P < 0.001). Good cord care practices were predicted by mothers’ age 30-46 (AOR = 3.6; CI: 1.4-9.1) and good knowledge of cord care (AOR = 4.7; 95% CI: 2.2-9.9).

CONCLUSIONS: The study has highlighted the good knowledge but poor practices of cord care by mothers and the need to scale up the uptake of CHX gel in Jos. Mother’s age and good knowledge of cord care are predictors of good cord care practices.

ABSTRACT

BACKGROUND: Kidney diseases requiring haemodialysis are becoming an emerging public health problem. This study aimed to determine the burden, socio-demographic and other risk factors associated with haemodialysis in Northwest Nigeria.

METHODOLOGY: The study was a retrospective multicentre review of secondary data from the dialysis centres of public hospitals in northwestern Nigeria. Risk factors for renal failure were examined in 1329 patients who were enrolled for haemodialysis between 2019 and 2022 in the four public dialysis centres in Kano and Jigawa state. Data were analysed using IBM SPSS Statistics for Windows, version 22.0, with statistical significance set at P ≤ 0.05.

RESULTS: The minimum age of the patients was 2 years and the maximum was 100 years with a median of 48 (interquartile range = 31, 60) years. Chronic kidney disease (CKD) was found amongst more than two-thirds 998 (75.1%) of the patients. Up to 51 (3.8%), 62 (4.7%) and 10 (0.8%) were seropositive for HIV, hepatitis B and hepatitis C, respectively. Acute kidney injury (AKI) was significantly higher (67.9%, P < 0.001) amongst patients with post-partum haemorrhage (PPH), and were 24 times more likely to develop AKI when compared with those with no PPH (adjusted odds ratio [aOR] =24, 95% confidence interval [CI] = [13.5-44.5]). CKD was significantly higher amongst patients with hypertension (HTN) (84.9%, P < 0.001), and were 3.2 times more likely to develop CKD compared with non-hypertensives (aOR = 3.2, 95% CI = [2.4-4.1]). Acute on CKD (AOCCKD) was significantly higher amongst patients with chronic glomerulonephritis (CGN) (28.1%, P < 0.001), and were three times more likely to develop AOCCKD than those without CGN (aOR = 3, 95% CI = [2.1-4.2]).

CONCLUSION: PPH was the major reason for AKI related haemodialysis while diabetes and HTN were the major causes of CKD-requiring haemodialysis. CGN was more amongst patients who had dialysis due to acute exacerbation of CKD. The government and relevant stakeholders should ensure a favourable policy for the screening and management of patients.

ABSTRACT

INTRODUCTION: Sleep disturbance is common in persons with stroke and when unrecognised and untreated may hinder rehabilitation efforts and lead to poor functional outcome. It may also result in increased risk for stroke recurrence.

AIM: We investigated the frequency and associated factors of sleep disturbances amongst stroke survivors.

METHODOLOGY: One hundred and ten stroke survivors attending the neurology outpatient clinics of two tertiary hospitals, from February 2021 to January 2022, were interviewed after obtaining ethical approval and informed consent. We used a structured questionnaire to obtain their socio-demographic, clinical characteristics and sleep disturbances. Excessive daytime sleepiness was assessed using the Epworth Sleepiness Scale (ESS). Data were analysed with statistical significance set at P < 0.05.

RESULTS: Eighty (72.7%) patients were males with a mean age of 61.4 ± 11.8, slightly older than the females (30, 27.3%) with a mean age of 60.9 ± 2.9. Their median follow-up duration was 7.5 months. Majority (84, 76.4%) had ischaemic stroke, and the frequency of sleep disturbances was 37 (33.6%) consisting of insomnia (19, 17.3%), hypersomnia (10, 9.0%), sleep-disordered breathing (5, 4.5%) and sleep-related movement disorder (3, 2.7%), respectively. Using the ESS score, 22 (20.0%) had mild, 10 (9.0%) had moderate and 7 (6.4%) had severe ESS scores, respectively. Univariate analysis showed depression to be significantly associated with ESS (P = 0.006) whereas multivariate analysis revealed age and sex as significant associated factors (P = 0.008 and P = 0.009) of ESS.

CONCLUSION: More than one-third of participants reported sleep disturbances with depression, age and gender as associated factors.

ABSTRACT

BACKGROUND & OBJECTIVES: Despite being a tropical country, vitamin D deficiency is highly prevalent in India with studies indicating 40-99 per cent prevalence. Apart from calcium and phosphate metabolism, vitamin D is involved in cell cycle regulation, cardiovascular, hepatoprotection. The metabolism of vitamin D is regulated by vitamin D tool genes (CYP2R1/CYP27B1/CYP24A1/VDR). The promoter regions of some of these genes have CpG islands, making them prone to methylation induced gene silencing, which may cause a reduction in circulating vitamin D levels. Epigenetic basis of vitamin D deficiency is yet to be studied in India, and hence, this pilot study was aimed to analyze whether methylation levels of CYP2R1 gene were correlated with the levels of 25(OH)D in healthy, adult individuals in Indian population.

METHODS: In this cross-sectional study, healthy adults of 18-45 yr of age with no history of malabsorption, thyroidectomy, chronic illness or therapeutic vitamin D supplementation were recruited. DNA methylation analysis was carried out by methylation specific quantitative PCR. Serum calcium, phosphate and vitamin D levels were also quantified. Statistical analysis was done by R 4.0.5 software.

RESULTS: A total of 61 apparently healthy adults were analyzed. The serum vitamin D levels did not correlate with CYP2R1 methylation levels in our study population. Significant positive correlation was observed between age and serum vitamin D levels. Significant association of gender was found with CYP2R1 methylation levels.

INTERPRETATION & CONCLUSIONS: This study found no significant correlation between levels of CYP2R1 methylation and circulating 25(OH)D deficiency. Further studies on the Indian population having a larger sample size including entire vitamin D tool genes, among different ethnic groups may be conducted to elucidate molecular etiology of circulating 25(OH)D deficiency. The high prevalence of normal serum calcium and phosphate levels among vitamin D deficient subjects in this study coupled with the strikingly high prevalence of the deficiency at the national level, may suggest the need to revise the cut-off criteria for vitamin D deficiency in the Indian population.
