OCCUPATIONAL HEALTH AND SAFETY PRACTICES AMONG WORKERS IN BLOCK/CONCRETE CONSTRUCTION INDUSTRIES IN GOMBE METROPOLIS, GOMBE STATE, NORTHEAST, NIGERIA

Introduction

The block/concrete industry is often seen as a driver of economic growth in developing countries. A wide range of people mainly unskilled form the bulk of workers in these industries. According to the International Labor Organization, about 60,000 fatal accidents occur annually on these construction sites. This study aimed to determine the knowledge of hazards and practices of occupational safety measures among the workers in these industries.

Methodology

A descriptive cross-sectional study was done among 295 respondents selected using a multi-stage sampling technique. A structured, interviewer-administered-electronic questionnaire was used to obtain information from the respondents. Data were analyzed using SPSS version 23. Quantitative variables were summarized using tables and charts. The chi-square test was used to examine the relationship between socio-demographic characteristics and knowledge and practice. Statistical significance was determined at a p-value of ≤0.05.

Results

All the respondents were males, with a mean age of 28.9 ± 6.9 years. Most (70%) of the respondents have good knowledge while 49% have good practices in occupational safety. The age, level of education, and status of the worker were associated with knowledge of occupational hazards and practices. There was a statistically significant relationship between the knowledge of hazards and the practice of occupational safety (p = 0.000).

Conclusion

The knowledge of occupational hazards among the study participants was high while safety practices were not adequate. Therefore, the health authorities should educate workers on safety practices and encourage the management of the factories to provide safety measures to protect the workers.

AWARENESS AND PRACTICES TOWARDS PREVENTION OF MOTHER-TO-CHILD TRANSMISSION OF HIV AMONG MARRIED MEN ATTENDING THE ANTIRETROVIRAL CLINIC IN AMINU KANO TEACHING HOSPITAL, KANO, NIGERIA

Background

The prevention of mother-to-child transmission (PMTCT) of HIV programme was introduced as a comprehensive package of interventions with the aim of reducing mother-to-child transmission (MTCT) of HIV. The programme offers an opportunity to capture pregnant women and their partners in order to prevent the transmission of HIV to the baby. This study is aimed at assessing the awareness and practices of married HIV-positive male partners towards PMTCT.

Methodology

A descriptive cross-sectional study that interviewed 220 HIV-positive male partners using an interviewer-administered questionnaire.

Results

The study revealed that more of the respondents 145 (65.9%) were between the age group of 31 to 40 years. More than half 130 (59%) of the respondents were aware of PMTCT while 135 (61.4%) of the respondents had good practice of PMTCT. Respondents with formal education were 1.5 times more likely to be aware of the PMTCT programme than those having informal education [p=0.03, AOR=1.53, 95%CI=(1.98-4.54)]. Similarly, respondents with formal education were 2.5 times more likely to practice PMTCT programme than those having informal education [p=0.03, AOR=2.53, 95%CI= (1.63-4.54)].In addition, Male partners who were above 30 years of age were 3 times more likely to participate in PMTCT activities compared to those who were less than 30 years [p=0.02, AOR=2.17, 95%CI=(0.01-4.12)].

Conclusion

Raising awareness about the need for male partners' involvement in the PMTCT programme as well as encouraging male partners to partake in PMTCT activities will further increase its uptake.

[Correction of enteral distress syndrome in acute intestinal obstruction]

OBJECTIVE

On the basis of a comprehensive assessment of the functional state of the intestine in acute mechanical small bowel obstruction, to justify adequate schemes of its protection.

MATERIAL AND METHODS

A clinical and laboratory study of 48 patients with acute small bowel obstruction developed against the background of abdominal adhesions, strangulated abdominal hernia was conducted. The first group (n=25) of patients who underwent laparotomy, removal of intestinal obstruction (adhesiolysis and/or herniation, hernial gate plastic surgery), intestinal intubation, standardized therapy after surgery. The second group (n=23) - patients, therapy included Remaxol (Polysan Pharmaceutical Plant, Petersburg): 400.0 enterally intraoperatively through a probe after nasointestinal intubation, evacuation of stagnant contents and intestinal lavage with isotonic saline solution; 400.0 - intravenously for 5 days. A number of indicators of homeostasis (endogenous intoxication, oxidative stress), structural and functional state of the intestine were evaluated.

RESULTS

It was found that the inclusion of remaxol in complex therapy (intraoperatively and in the early postoperative period) leads to the optimization of the treatment process of patients with acute intestinal obstruction. The number of complications according to the Clavien-Dindo classification decreased from 17 (first) up to 5 (second group) (χ²=3.988, p=0.046). Hospital stay decreased from 12.8±1.1 to 10.1±0.8 bed days (p<0.05). The effectiveness of the developed scheme is based on its ability to correct the phenomena of enteral distress syndrome relatively quickly, which was confirmed by laboratory and instrumental methods. The most important manifestation of this was a significant decrease in the phenomena of endogenous intoxica tion against the background of a significant decrease in the activity of peroxidation of membrane lipids - triggers of catabolic intestinal lesions.

CONCLUSION

Studies document the effectiveness of the developed treatment regimen for patients with acute intestinal obstruction. The inclusion of remaxol parenterally and enterally makes it possible to significantly optimize the course of the early postoperative period. One of the main objects of its implementation was the relatively rapid restoration of intestinal function, reduction of manifestations of enteral distress syndrome. This provided rapid relief of endogenous intoxication and, as a result, prevented the progression of the systemic inflammatory response syndrome, which together determined the optimization of the early postoperative period.
