Incidence and determinants of diabetic ketoacidosis among people with diabetes in Woldiya comprehensive specialized hospital, Ethiopia: a retrospective cohort study.

INTRODUCTION: Diabetic ketoacidosis is an acute complication of diabetes mellitus that is characterised by hyperglycemia, acidosis, and ketonuria. Diabetes is the most challenging public health problem in the twenty-first century for both developed and developing countries. OBJECTIVE: To assess the incidence of Diabetic ketoacidosis and its determinants among adult people with diabetes at an Ethiopian Hospital. METHOD: An institution-based retrospective cohort study was conducted among 390 adult people with diabetes attending services at Wolida Comprehensive Specialized Hospital. The consecutive sampling method was used to select study participant charts. Data were collected using a checklist prepared from different literature. The data were entered into EPI data version 4.6.0.5 and exported to STATA version 14.0 for further analysis. The Wiebull model was the best fitted model that was selected using the log-likelihood ratio method and the Akakian information criterion. Hazard ratios with their 95% confidence interval and p-value were computed. RESULT: From the total 405 charts reviewed, 390 adult charts were included for analysis. A total of 121 DKA occurred from 5471 person-months of observation. The overall incidence rate of diabetic ketoacidosis was found to be 2.2 per 100 person-months (95% CI: 1.8- 2.6). Being urban dweller (AHR: 0.59, 95% CI: 0.36-0.99), having no family history of DM (AHR: 0.55, 95%CI: 0.31-0.97), presence of infection (AHR: 2.60, 95%CI = 1.06-6.39), having of any comorbidities (AHR: 4.31, 95% CI: 1.70-10.90), and having poor glycemic control (AHR: 7.45, 95% CI: 3.84-14.47) were significant determinants. CONCLUSION AND RECOMMENDATIONS: The overall incidence of diabetic ketoacidosis in study area was relatively high. Poor glycemic control, the presence of infection, and comorbidity were determinants of diabetic ketoacidosis. There is a need to have close follow-up of people with diabetes who have comorbidity, infection, and poor glycemic control.

The comparative study on the performance of bamboo fiber and sugarcane bagasse fiber as modifiers in asphalt concrete production.

Highway pavement structures are expected to be adequately strong and durable for their design life which can be achieved only when the pavements are properly designed, constructed, maintained, and managed. In Ethiopia, most of the asphalt pavement is suffering from fatigue, creep, and rutting in long term. These stresses may be occurred due to the shortage in the mechanistic properties of either the binder or the asphalt mixtures as well as due to the increase in traffic loads. Failures of some roads can be attributed to the poor design of the asphalt mixes and materials being used. The properties and dosage of additive materials in hot mix asphalt affect the overall performance of pavement structure. Hence, modifying the properties of asphalt is necessary to enhance the performance of HMA. This study aims to investigate the performance of bamboo fiber and sugarcane bagasse fiber on the mechanical properties of Hot Mix Asphalt production. This research was conducted by using an experimental research design method and Non-Probability sampling techniques were adopted to collect samples. A sample preparation method of asphalt mixture specimens for asphalt mix design was performed based on AASHTO, ASTM and EN Standard specifications. The tests required were aggregate tests, a Bitumen test, Marshall test, and performance tests such Indirect Tensile Strength test and Rutting Test (RT) were conducted to evaluate a comparative study on the performance of bamboo fiber and sugarcane bagasse fiber as a modified Hot Mix Asphalt production. The preparing HMA mixes using crushed stone coarse aggregate, Fine aggregate, Mineral fillers 60/70 Bitumen, and by using bamboo and sugar cane bagasse fiber as additives were used to compare the results at a varying bitumen content of 4.5,5,5.5,6% bitumen. The Asphalt additives were used in the range from 0.2% to 0.5% of the total weight of the sample. Then, finally, the results of the laboratory were compared to standards of specifications. The optimum both fibers content obtained at 0.3% and OAC & OMF (5.2% & 4%) respectively, suggests that using both BF & SCBF fibers in asphalt concrete mixture improves the performance of asphalt pavements to resist external loads. Both fibers at 0.3% content better modify asphalt marshal stability, ITS of HMA, and Rutting resistance of AC. Finally, based on this study it was proved that the performance and properties of Asphalt concrete are affected by Fiber type and its content.

Patient safety knowledge, attitude and practice among undergraduate health science students in South West Ethiopia.

Background: Patient safety is minimizing the risk of unnecessary damage associated with healthcare to a minimum. It has been linked as a global precedence area where substantial knowledge gaps exist. Knowledge, attitude, and practice of the healthcare providers toward patient safety have a great influence on the delivery of safe patient care. Regardless of this, the issue has not been adequately addressed in Ethiopia. Objective: The main aim of this study was to assess the knowledge, attitude, practice, and factors associated with patient safety practice among undergraduate health science students at Jimma University Institute of Health. Methods: An institution-based cross-sectional study design was conducted from May to November 2021. Data were collected from 678 undergraduate health science students using a pretested, structured and self-administered questionnaire. EPI data 3.1 was used for data entry, and SPSS version 25 was used for analysis. A binary logistic regression model was utilized to identify factors associated with outcome variables. An adjusted odds ratio with a 95% confidence interval and P < 0.05 were computed to determine the level of significance. Results: Of the total students, only 293 (43.2%) and 308 (45.4%) had good knowledge and positive attitudes toward patient safety, respectively. Moreover, only 135 (19.9%) of the students had good practices regarding patient safety. Year of study [AOR = 3.75, 95% CI: (2.3, 9.3)], duration on practical attachment [AOR = 2.6, 95% CI: (1.2, 5.9)], and knowledge about patient safety [AOR = 2.9, 95% CI: (1.9, 3.4)] were associated with better patient safety practices. Conclusion: In the current study the practice of patient safety among health science students was low and less than half of the students had good knowledge and favorable attitudes toward patient safety. Patient safety practices were influenced by the length of the clinical attachment, the study year, and the knowledge of patient safety. This calls for patient safety courses to be included in training curricula of undergraduate health sciences students.

Determinants of Virologic Failure Among Adults on Second Line Antiretroviral Therapy in Wollo, Amhara Regional State, Northeast Ethiopia.

BACKGROUND: Treatment failure among the population on second line antiretroviral therapy is a major public health threat. In Ethiopia there has been limited research done on second line treatment failure. OBJECTIVE: To identify determinants of virologic failure among adults on second line antiretroviral therapy in six public hospitals of Wollo, Amhara regional state, northeast Ethiopia. METHODS: An institution-based unmatched case-control study was conducted from February 1, 2020 to April 30, 2020 on a total of 377 clients in six public hospitals of Wollo, Amhara regional state, northeast Ethiopia. Clients whose viral load result >1,000 copies/mL in two consecutive results at least 3 month apart were cases, while ≤1,000 copies/mL were controls. The sample size was calculated by using Epi-Info version 7. Cases (94) and controls (283) were selected using a simple random sampling method in a ratio of cases-to-controls of 1:3. The model fitted and binary logistic assumptions were fulfilled with 95% confidence level and P-values<0.05 were taken as statistically significant. RESULTS: Virologic failure was predicted by poor adherence (AOR=6.060, 95% CI=2.837-12.944), not disclosing their HIV status (AOR=4.178, 95% CI=1.431-12.198), OI (AOR=4.11, 95% CI=1.827-9.246), CD4 count <100 cells/mm3 (AOR=3.497, 95% CI=1.233-9.923) and 100-350 cells/mm3 (AOR=5.442, 95% CI=2.191-13.513), low BMI <16 kg/m2 (AOR=7.223, 95% CI=2.218-23.520), and young age 15-29 years (AOR=2.898, 95% CI=1.171-7.170). CONCLUSION AND RECOMMENDATIONS: Determinants of second line ART virologic failure were patients who had poor adherence to ART, not disclosed, opportunistic infection, low CD4 counts <350 cell/mm3, low BMI (<16 kg/m2), and young age 15-29 year patients. Social support, disclosing their HIV status, and getting early treatment for any opportunistic infection is crucial to patients.

Role of Anti-inflammatory Drugs in the Colorectal Cancer.

Objective: The objective of this review was to systematically review and synthesize evidence regarding benefits of using nonsteroidal anti-inflammatory drugs (NSAIDs) for the treatment of colorectal cancer (CRC). Data Sources: The data sources were MEDLINE, PubMed, NEJM, Google Scholar, and Google searches of references from relevant and eligible trials. Review Methods: We screened abstracts and full-text articles of identified references for eligibility and reviewed randomized controlled trials, cohort studies, and meta-analysis for evidence on benefits of using NSAIDs in CRC treatments. For all extracted data, completeness and relevance were checked. Results: The risk of any adenoma among frequent NSAID users was 26.8% vs 39.9% among placebo subjects who later used NSAIDs sporadically (adjusted relative risk = 0.62, 95% confidence interval [CI] = 0.39-0.98; P trend with NSAID use frequency = .03). Long-term use of aspirin reduces the risk of CRC. Aspirin also reduces the incidence of colon adenomas and mortality, especially when used for >10 years. Rofecoxib is associated with the reduction of CRC; however, it was associated with cardiovascular risk (with an overall unadjusted relative risk of 1.50 [95% CI = 0.76-2.94; P = .24]). Adenoma Prevention with Celecoxib trial shows that, for patients of all genotypes, the estimated cumulative incidence of one or more adenomas by year 3 was 59.8% for those randomized to placebo as compared with 43.3% for those randomized to low-dose (200 mg, twice daily) celecoxib (relative risk [RR] = 0.68; 95% CI = 0.59-0.79; P < .001) and 36.8% for those randomized to high-dose (400 mg, twice daily) celecoxib and 60.7% in placebo group (RR = 0.54; 95% CI = 0.46-0.64; P < .001). Conclusions: The use of COX-2 inhibitors both prior to and after diagnosis of CRC seemed to be mildly associated with the reduction in mortality of patients with CRC. Some literatures state that COX-2 inhibitors might play a synergistic role in adjuvant chemotherapy of FOLFOX regimen. Celecoxib was found to increase the radiosensitization of colon cancer cells.

[McGregor's flap: a salvage technique: about a case, clinical features and outcome]. / Lambeau de Mac Gregor, solution de sauvetage: à propos d'un cas, clinique et résultat.

Inguinal flap is a distant axial pediculated flap. This flap is reliable in covering large losses of substance of the upper limb. Its major drawback is that it requires two-step surgery. Inguinal flap is the elective method in the arsenal of emergency left hand surgery or in common left hand surgery. This is due to its greasy thickness and its short small pedicle, with frequent anatomical variations. The purpose of this study was to show its role imbalance out its advantages and its disadvantages. We report the case of a 33-year female patient presenting with severe deformation with closure of the anterior commissure and first metacarpophalangeal joint ankylosis after complex open trauma of the hand. The patient underwent two-step surgery with opening the first commissure and trapezio-M1 arthrodesis stabilized by plug insertion followed by immediate skin coverage by McGregor's inguinal flap and after 21days by weaning and donor site suture. Anatomical and functional outcome was good. The patient was satisfied with the scar at the donor site, which could be easily covered with clothing, by the functionality and aesthetics of the hand. McGregor's flap is an attractive solution for coverage with significant advantages from a functional and aesthetic point of view. Its role should be enhanced in the therapeutic armamentarium of flaps for limb coverage.

Attitude, reporting behavour and management practice of occupational needle stick and sharps injuries among hospital healthcare workers in Bale zone, Southeast Ethiopia: a cross-sectional study.

BACKGROUND: Although the prevalence of blood borne pathogens in many developing countries is high, documentation of infections due to occupational exposure is limited. Seventy percent of the world's HIV infected population lives in Sub-Saharan Africa, but only 4 % of cases are reported from this region. Under reporting of needle stick and/or sharps injuries in healthcare facilities was common. METHODS: An institutional based cross-sectional study was conducted in December 2014 among healthcare workers in four hospitals of Bale zone, Southeast Ethiopia. A total of 362 healthcare workers were selected randomly from each of the working departments. Data were collected using self-administered questionnaire and were entered using Epi-Info version 3.5 and analysed using SPSS version 20.0. Multivariable logistic regression analysis was used to identify independent effect of each variable on the reporting behaviour of needle stick and/or sharp injury. RESULTS: Nearly six out of ten injuries (58.7 %) were not reported to the concerned body. The main reasons for not reporting the injuries were time constraint (35.1 %), sharps which caused injury were not used on any patient (27.0 %), the source patients did not have disease of concern (20.3 %), and lack of knowledge that it should be reported (14.9 %). Half of healthcare workers (HCWs) those who experienced injury had sought medical care next to self based action. Respondents with monthly salary of 450 to 1000 Ethiopian Birr (1 US Dollar = 22.00 Ethiopian Birr) were about six times more likely to report occupational needle stick and/or sharps injury (NSSI) than HCWs with salary of 2001 to 8379 birr (AOR = 5.73). However, HCWs who had no knowledge about probability of infection transmission through NSSI and not taking any self based measures after occurrence of injury were 45 % (AOR = 0.55) and 93 % (AOR = 0.07) less likely to report occupational injury than their counterparts, respectively. CONCLUSIONS: Occupational needle stick and/or sharps injuries are common among HCWs at the study area. Even though majority of respondents were concerned about the risk of NSSI exposure, most respondents did not report it to the concerned body. Therefore, provision of on job training on the risk of occupational NSSI exposure may strengthen HCWs to practice timely reporting and its management in case of occupational injury exposure.

Factors Associated with Occupational Needle Stick and Sharps Injuries among Hospital Healthcare Workers in Bale Zone, Southeast Ethiopia.

BACKGROUND: Needle stick and sharps injuries are occupational hazards to healthcare workers. Every day healthcare workers are exposed to deadly blood borne pathogens through contaminated needles and other sharp objects. About twenty blood borne pathogens can be transmitted through accidental needle stick and sharp injury. The study was conducted to determine the lifetime and past one year prevalence of needle stick and sharps injuries and factors associated with the past one year injuries among hospital healthcare workers in Southeast Ethiopia. METHODS: An institutional based cross sectional study was conducted in December 2014 among healthcare workers in four hospitals of Bale zone, Southeast of Ethiopia. A total of 362 healthcare workers were selected randomly from each department in the hospitals. Data were collected using self-administered questionnaire. The collected data were entered into Epi-Info version 3.5 and analyzed using SPSS version 20.0. Multivariable logistic regression analysis was used to identify the independent effect of each independent variable on the outcome variable. Written informed consent was secured from the participants. RESULTS: The prevalence of lifetime needle stick and sharp injury was 37.1% with 95% CI of 32.0% to 42.5%. The prevalence of injury within the past one year was 19.1% with 95% CI of 14.9% to 23.3%. Emergency ward was a department with highest needle stick and sharp injury (31.7%). The main cause of injury was syringe needles (69.8%). Participants who practiced needle recapping had higher odds of needle stick and sharp injury within the past 12 months (AOR = 3.23, 95% CI: 1.78, 5.84) compared to their counterparts. CONCLUSIONS: Nearly one out of five respondents had experienced needle stick and/or sharp injury at least once within past one year. There were practices and behaviors that put healthcare workers at risk of needle stick and sharp injury at the study area. Needle recapping was key modifiable risk behavior. Health policy makers and hospital administrators should formulate strategies to improve the working condition for healthcare workers and increase their adherence to universal precautions.

Lead exposure study among workers in lead acid battery repair units of transport service enterprises, Addis Ababa, Ethiopia: a cross-sectional study.

BACKGROUND: Lead exposure is common in automobile battery manufacture and repair, radiator repair, secondary smelters and welding units. Urinary Aminolevulinic acid has validity as a surrogate measure of blood lead level among workers occupationally exposed to lead. This study had therefore assessed the magnitude of lead exposure in battery repair workers of three transport service enterprises. METHODS: To this effect, a cross-sectional study was carried out on lead exposure among storage battery repair workers between November 2004 and May 2005 from Anbasa, Comet and Walia transport service enterprises, Addis Ababa, Ethiopia. Subjective information from the workers was obtained by making use of structured questionnaire. Other information was obtained from walkthrough evaluation of the repair units. Aminolevulinic acid levels in urine were used as an index of the exposure. This was coupled to measurements of other relevant parameters in blood and urine collected from adult subjects working in the repair units as well as age matched control subjects that were not occupationally exposed to lead. Aminolevulinic acid was determined by spectrophotometry, while creatinine clearance, serum creatinine, urea and uric acid levels were determined using AMS Autolab analyzer. RESULTS: Urinary aminolevulinic acid levels were found to be significantly higher in exposed group (16 mug/ml +/- 2.0) compared to the non-exposed ones (7 mug/ml +/- 1.0) (p < 0.001). Alcohol taking exposed subjects exhibited a significant increase in urinary aminolevulinic acid levels than non-alcohol taking ones (p < 0.05). Moreover, urinary aminolevulinic acid levels of exposed subjects increased with age (p < 0.001) as well as duration of employment (p < 0.001). Whereas serum uric acid levels of exposed subjects was significantly higher than non-exposed ones (p < 0.05), no statistically significant difference had been found in renal indices and other measured parameters between exposed and non-exposed subjects. From the questionnaire responses and walkthrough observations, it was also known that all the repair units did not implement effective preventive and control measures for workplace lead exposure. CONCLUSION: Taken together, these findings indicated that workers in lead acid battery repair units of the transport service enterprises are not protected from possibly high lead exposure. Thus, strict enforcement of appropriate and cost effective preventive and control measures is required by all the enterprises.
