Chronic obstructive pulmonary disease in East Africa: a systematic review and meta-analysis.

Chronic obstructive pulmonary disease (COPD) is a common lung disease that causes restricted airflow and breathing problems. Globally, COPD is the third leading cause of death and low- and middle-income countries account for the majority of these deaths. There is limited information on COPD's prevalence in East Africa. Thus the purpose of this systematic review and meta-analysis is to estimate the pooled prevalence of COPD in East Africa.A computerized systematic search using multiple databases was performed in search of relevant English articles from the inception of the databases to August 2023. All the authors independently extracted the data. R and RStudio software were used for statistical analysis. Forest plots and tables were used to represent the data. The statistical heterogeneity was evaluated using I2 statistics. There was heterogeneity between the included articles. Therefore, a meta-analysis of random effects models was used to estimate the overall pooled prevalence of COPD in East Africa. A funnel plot test was used to examine possible publication bias.The database search produced 512 papers. After checking for inclusion and exclusion criteria, 43 full-text observational studies with 68 553 total participants were found suitable for the review. The overall pooled prevalence of COPD in East Africa was 13.322%. The subgroup analysis found the COPD pooled prevalence in the different countries was 18.994%, 7%, 15.745%, 9.032%, 15.026% and 11.266% in Ethiopia, Uganda, Tanzania, Malawi, Sudan, and Kenya, respectively. Additionally, the subgroup analysis of COPD by study setting among community-based studies was 12.132% and 13.575% for hospital-based studies.According to the study's findings, approximately one of every seven individuals in East Africa has COPD, indicating a notably high prevalence of the disease. Thus governments and other stakeholders working on non-communicable disease control should place an emphasis on preventive measures to minimize the burden of COPD.

Rheumatic Heart Disease in East Africa: A Systematic Review and Meta-Analysis.

Background: Despite being a grave problem, there is little information on rheumatic heart disease's prevalence in East Africa. Therefore, the purpose of this systematic review and meta-analysis was to estimate the pooled prevalence of rheumatic heart disease in East Africa. Materials and Methods: A computerized systematic search of using multiple database searching engines was performed in search of relevant English articles from the inception of the databases to December 2019. It was done in accordance with the preferred reporting items for systematic review and meta-analysis (PRISMA) standard. The funnel plot was used to assess publication bias. R and RStudio for Windows were used for all statistical analysis. The random-effect model was used for calculating the pooled estimate of the prevalence of rheumatic heart disease. Results: The database search retrieved 1073 papers, and 80 articles (78 cross-sectional and two cohort study designs) with a total of 184575 individuals were found to be appropriate for the review. In East Africa, the overall prevalence of rheumatic heart disease was 14.67% (95% CI: 13.99% to 15.35%). In Ethiopia, Uganda, Tanzania, and Sudan, respectively, the subgroup analysis of rheumatic heart disease pooled prevalence was 22% (95% CI: 13% to 36%), 11% (95%t CI: 5% to 20%), 9% (95%t CI: 5% to 16%), and 3% (95%t CI: 1% to 10%), while the pooled prevalence of rheumatic heart disease in adults was 20% (95% CI: 12% to 30%), and in children, it was 4% (95% CI: 2% to 8%). Conclusions: From this report, the prevalence of rheumatic heart disease in East Africa is very high, affecting about one in seven people. Therefore, future strategies should emphasize preventive measures at appropriate times to minimize the burden of this type of preventable heart disease.

Time to recovery from severe acute malnutrition and its predictors among under five children admitted to therapeutic feeding units of general and referral hospitals in Tigray, Ethiopia, 2020: a prospective cohort study.

BACKGROUND: Across the globe, an estimated 16 million children under the age of 5 are affected by severe acute malnutrition. Children with severe acute malnutrition are nine times more likely to die than well-nourished children. In Ethiopia, 7% of children under five are wasted, and 1% of these are severely wasted. A prolonged hospital stay increases the incidence of hospital-acquired infections. The aim of this study was to assess the time to recovery and its predictors among children 6-59 months old with severe acute malnutrition admitted to therapeutic feeding units of selected general and referral hospitals in Tigray, Ethiopia. METHODS: A prospective cohort study design was conducted among children aged 6-59 months admitted with severe acute malnutrition in selected hospitals in Tigray that have therapeutic feeding units. The data were cleaned, coded, entered into Epi-data Manager, and exported to STATA 14 for analysis. RESULT: Among 232 children followed in the study, 176 have recovered from severe acute malnutrition with a recovery rate of 54 per 1000 person-days observation and the median time to recovery was 16 days with an inter-quartile range of 8. In a multivariable Cox Regression, feeding plumpy nut [AHR 0.49 (95% CI 0.2717216-0.8893736)] and failing to gain 5 gr/kg/day for three successive days after feeding freely on F-100 [AHR 3.58 (95% CI 1.78837-7.160047)] were found to have an association with time to recovery. CONCLUSION: Despite the median time to recovery is shorter than what has been reported in a few studies, we can conclude that this could not let children avoid any possible hospital-acquired infections. The impact of staying in a hospital may also extend to the mother/caregiver in terms of the infection that they may acquire or the costs imposed on them.

Prevalence of neonatal near miss in Africa: a systematic review and meta-analysis.

BACKGROUND: Neonatal near miss (NNM) applies to cases where newborns almost died during the first 28 d of life but survived life-threatening conditions following birth. The most vulnerable time for infant survival is the neonatal stage, corresponding to almost 50% of deaths occurring at <5 y of age. No study indicates the overall pooled prevalence of NNM in Africa. Thus this review aimed to estimate the overall pooled prevalence of NNMs in Africa. METHODS: Articles were retrieved through a comprehensive search strategy using PubMed/MEDLINE, Embase, Health InterNetwork Access to Research Initiative, Cochrane Library and Google Search. Data extraction was done independently by all authors. Forest plots and tables were used to represent the original data. The statistical heterogeneity was evaluated using I2 statistics. There was heterogeneity between the included articles. Therefore the authors used a meta-analysis of random effects to estimate the aggregate pooled prevalence of NNM in Africa. Funnel plot and Egger regression test methods were used to assess possible publication bias. R software version 3.5.3 and R studio version 1.2.5003 were used to analyse the data. The guideline of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses was used to publish this article. The review was registered on the International Prospective Register of Systematic Reviews (registration ID: CRD42021290223). RESULTS: Through an exhaustive search, we found 835 articles. However, we considered only eight full-text articles to be included in this meta-analysis. The analysis of included studies showed that the overall pooled prevalence of NNM in Africa was 30% (95% confidence interval [CI] 16 to 44). The subgroup analysis by study year showed that the prevalence of NNM from 2012-2015 and 2018-2019 was 36% (95% CI 23 to 49) and 20% (95% CI 1 to 39), respectively. CONCLUSION: This finding suggests that the pooled prevalence of NNM is high in Africa as compared with other studies. Therefore the government and other stakeholders working on maternal and child health should assist in the design of interventions and strategies for improving the quality of neonatal care.

Knowledge, attitude, and practice towards COVID-19 among chronic disease patients at Aksum Hospital, Northern Ethiopia, 2020: a cross-sectional study.

BACKGROUND: The Coronavirus disease 2019 outbreak is the first reported case in Wuhan, China in December 2019 and suddenly became a major global health concern. Currently, there is no vaccine and treatment have been reported. The aim of this study was to assess the knowledge, attitude, and practice of COVID-19 among chronic disease patients. METHODS: A hospital-based cross-sectional study was conducted among 422 chronic disease patients from July 01 to August 30, 2020 at Aksum Hospital, Northern Ethiopia. Both bivariable and multivariable logistic regression analyses with 95% confidence intervals were fitted to identify factors associated with poor knowledge and practice towards COVID-19. The adjusted odds ratio (AOR) was used to determine the prevalence of the association between the dependent and independent variables. A P-value < 0.05 was identified as statistically significant. RESULTS: A total of 422 participants participated in this study, with a 100% response rate. The prevalence of poor knowledge, poor practice and unfavorable attitude was 35.1, 48.8, and 40.5%, respectively. Age (AOR = 1.5, 95% CI: (1.411, 2.432)), educational status of "can't read and write" (AOR = 1.4, 95% CI: (1.332, 9.612)), and rural residence (AOR = 3.12, 95% CI: (2.568, 11.532)) were significantly associated with poor knowledge. Educational status of "can't read and write" (AOR = 2.7, 95% CI (1.03-7.29)), and rural residence (AOR = 2.7, 95% CI (1.09-6.70)) were significantly associated with poor practice. CONCLUSIONS: The prevalence of poor knowledge and poor practice among chronic disease patients were high. Rural residence and educational status with "can not read and write" were significantly associated with poor knowledge and poor practice. Older age was significantly associated with poor knowledge.

Magnitude of Overweight and Obesity and Associated Factors Among Public and Private Secondary School Adolescent Students in Mekelle City, Tigray Region, Ethiopia, 2019: Comparative Cross-Sectional Study.

BACKGROUND: Overweight and obesity emerged as one of the most serious public health concerns in adolescents. Overweight and obesity are problems of not only high income but also low-middle income countries. Therefore, this study aimed to assess the magnitude and associated factors of overweight and obesity among public and private secondary school adolescents in Mekelle city, Tigray, Ethiopia, 2019. MATERIALS AND METHODS: A school-based comparative cross-sectional study was conducted in Mekelle city, from April to May 2019. A multi-stage sampling technique was used to select 858 participants. Chi-square test was checked before bivariate logistic regression analyses. All variables at a p-value <0.25 in bivariate logistic regression were entered into a multivariable logistic regression to determine the association between a set of independent variables with the dependent variable. Finally, statistical significance was declared at a p-value <0.05. RESULTS: The magnitude of overweight and obesity in private and public schools were 11.8% and 3.9%, respectively. Consuming dinner not daily [AOR=5.3:95% CI=1.93-14.6] and working moderate-intensity sports at least 10 minutes/day continuously [AOR=0.19:95% CI=0.04-0.9] were associated factors of overweight and obesity in public school adolescent students. Being female [AOR=2.03:95% CI=1.08-3.8], time taken from home to public physical activities ≤15 minutes [AOR=3.6:95% CI=1.13-11.51], using transport from school to home [AOR=2.2:95% CI=1.06-4.18] and good knowledgeable adolescents [AOR=0.5:95% CI=0.27-0.9] were associated factors of overweight and obesity in private schools. CONCLUSION: The magnitude of overweight and obesity was higher among private schools. Consuming dinner not daily and working moderate-intensity sports at least 10 minutes/day continuously were the associated factors for the occurrence of overweight and obesity in public school adolescent students. Being female, time taken from home to public physical activity facilities ≤15 minutes, using transport from school to home, and nutritional knowledge status of adolescents were associated factors for overweight and obesity in private school adolescent students.

Diabetic Peripheral Neuropathy in Ethiopia: A Systematic Review and Meta-Analysis.

BACKGROUND: Currently, diabetic peripheral neuropathy (DPN) is one of the most severe complications of diabetes mellitus (DM). Despite the seriousness of this problem, limited evidence is available on the prevalence of diabetic peripheral neuropathy among patients with diabetes mellitus in Ethiopia. In Ethiopia, there were no updated studies that estimate the national prevalence of DPN. Hence, this systematic review and meta-analysis provided a national prevalence of diabetic peripheral neuropathy among patients with diabetes mellitus in Ethiopia. METHODS: This study was submitted for registration with the International Prospective Register of Systematic Reviews (PROSPERO) in March 2020 and accepted with the registration number CRD42020173831. Different database searching engines were searched online to retrieve related articles, including PubMed, Scopus, Google Scholar, African Journals Online, World Health Organization (WHO) Afro Library, and Cochrane Review. The reviewers used the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guideline in the reviewing process. In this systematic review and meta-analysis, all published and unpublished articles were analyzed. The reviewers used the random effects model to estimate the pooled prevalence of diabetic peripheral neuropathy among diabetes mellitus patients. The reviewers conducted the statistical analysis using the R version 3.5.3 and RStudio version 1.2.5033 software for Windows. The reviewers evaluated the heterogeneity across the included studies by the inconsistency index (I 2). The reviewers examined the publication bias by the funnel plot. RESULTS: The search of the databases produced 245 papers. After checking the inclusion and exclusion criteria, 38 articles with 14029 total patients with diabetes mellitus were found suitable for the review. Except for three (retrospective cohort study), all studies were cross-sectional. The overall pooled prevalence of diabetic peripheral neuropathy was 22% (95% CI 18% to 26%). The subgroup analysis of diabetic peripheral neuropathy among patients with diabetes in the different regions was 23% (95% CI 17% to 29%) in Addis Ababa, 27% (95% CI 16% to 38%) in Oromia, 16% (95% CI 14% to 18%) in South nation and nationalities, and 15% (95% CI 6% to 24%) in Amhara. CONCLUSIONS: More than one-fifth of patients with diabetes have diabetic peripheral neuropathy. According to this study, the prevalence of diabetic peripheral neuropathy in Ethiopia is considerably high. This evidence suggests that attention should be given to patients with diabetes in monitoring patients' blood glucose.

Determinants of Neonatal Jaundice among Neonates Admitted to Neonatal Intensive Care Unit in Public General Hospitals of Central Zone, Tigray, Northern Ethiopia, 2019: a Case-Control Study.

BACKGROUND: Neonatal jaundice is common a clinical problem worldwide. Globally, every year, about 1.1 million babies develop severe hyperbilirubinemia with or without bilirubin encephalopathy and the vast majority reside in sub-Saharan Africa and South Asia. Strategies and information on determinants of neonatal jaundice in sub-Saharan Africa are limited. So, investigating determinant factors of neonatal jaundice has paramount importance in mitigating jaundice-related neonatal morbidity and mortality. Methodology. Hospital-based unmatched case-control study was conducted by reviewing medical charts of 272 neonates in public general hospitals of the central zone of Tigray, northern Ethiopia. The sample size was calculated using Epi Info version 7.2.2.12, and participants were selected using a simple random sampling technique. One year medical record documents were included in the study. Data were collected through a data extraction format looking on the cards. Data were entered to the EpiData Manager version 4.4.2.1 and exported to SPSS version 20 for analysis. Descriptive and multivariate analysis was performed. Binary logistic regression was used to test the association between independent and dependent variables. Variables at p value less than 0.25 in bivariate analysis were entered to a multivariable analysis to identify the determinant factors of jaundice. The level of significance was declared at p value <0.05. RESULTS: A total of 272 neonatal medical charts were included. Obstetric complication (AOR: 5.77; 95% CI: 1.85-17.98), low birth weight (AOR: 4.27; 95% CI:1.58-11.56), birth asphyxia (AOR: 4.83; 95% CI: 1.617-14.4), RH-incompatibility (AOR: 5.45; 95% CI: 1.58-18.74), breastfeeding (AOR: 6.11; 95% CI: 1.71-21.90) and polycythemia (AOR: 7.32; 95% CI: 2.51-21.311) were the determinants of neonatal jaundice. CONCLUSION: Obstetric complication, low birth weight, birth asphyxia, RH-incompatibility, breastfeeding, and polycythemia were among the determinants of neonatal jaundice. Hence, early prevention and timely treatment of neonatal jaundice are important since it was a cause of long-term complication and death in neonates.

Non-adherence to inhaled medications among adult asthmatic patients in Ethiopia: a systematic review and meta-analysis.

BACKGROUND: Medication non-adherence is one of a common problem in asthma management and it is the main factor for uncontrolled asthma. It can result in poor asthma control, which leads to decreased quality of life, increase hospital admission, increased health care utilization, lost productivity, and mortality. To date, there have been no studies and protocols that estimated the pooled national prevalence of non-adherence to inhaled anti-asthmatic medications in Ethiopia. Therefore, the primary purpose of this systematic review and meta-analysis is to determine the pooled national prevalence of non-adherence to inhaled medications among asthmatic patients in Ethiopia. METHODS: Different database searching engines including PubMed, Scopus, Google Scholar, Africa journal online, World Health Organization afro library, and Cochrane review were systematically searched by using keywords such as "prevalence, non-adherence to inhaled medications, inhaled corticosteroids, and asthmatic patients" and their combinations. Six published observational studies that report the prevalence of non-adherence to inhaled medications were finally selected. The Preferred Reporting Items for Systematic Review and Meta-Analysis guideline was followed. Heterogeneity across the included studies was evaluated by the inconsistency index (I2). The random-effect model was fitted to estimate the pooled prevalence of non-adherence to inhale anti-asthmatic medications. All statistical analysis was done using R version 3.5.3 and R Studio version 1.2.5033 software for windows. RESULTS: The pooled national prevalence of non-adherence to inhaled medications among asthmatic patients was 29.95% (95% CI, 19.1, 40.8%). The result of this meta-analysis using the random-effects model revealed that there is high heterogeneity across the included studies. The result of subgroup analysis indicates that one out of three in the Oromia region and one out of five in the Amhara region asthmatic patients was non-adherent to their inhaled anti-asthmatic medications. CONCLUSION: the prevalence of non-adherence to inhaled anti-asthmatic medications was high. Thus, our finding suggests that one out of four asthmatic patients were non-adherent to inhaled medications. The ministry of health, health policymakers, clinicians, and other health care providers should pay attention to strengthening the adherence levels to inhaled anti-asthmatic medications, and country-based interventions should be developed to reduce the burden of non-adherence to inhaled anti-asthmatic medications.

Burnout among Nurses Working in Ethiopia.

BACKGROUND: Burnout is a condition of emotional exhaustion, depersonalization, and low personal accomplishment that can occur among individuals who work with people in some capacity. Nursing is a stressful profession that deals with human aspects of health and illness and can ultimately lead to job dissatisfaction and burnout. Although burnout among nurses has been addressed in previous research, the heterogeneous nature of the result findings highlights the need for a detailed meta-analysis in Ethiopia. Thus, this review is aimed at identifying the prevalence of burnout among nurses in Ethiopia. METHODS: A search strategy was implemented using electronic databases (PubMed/MEDLINE, Google Scholar, Web of Science, Cochrane Library, Africa-Wide Information, and African Index Medicus) which were systematically searched online to retrieve related articles using keywords. Studies which were included in this review were written in the English language because writing articles in other languages in Ethiopia is uncommon. The combination of key terms including "burnout", "nurse" and "Ethiopia", "systematic review" and protocols was used. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis checklist guideline was followed stepwise. All published articles starting from inception to February 2020 were included, and we did not find unpublished studies. Heterogeneity across the included studies was evaluated by the inconsistency index. All statistical analysis was done using R and RStudio software for Windows, and a random-effects model was applied to estimate the overall prevalence of burnout among nurses in Ethiopia. It is registered in PROSPERO (CRD42020188092). RESULTS: The database searched produced 1060 papers. After adjustment for duplicates and inclusion and exclusion criteria, seven articles with 1654 total nurses were found suitable for the review. Except for one cohort study, all studies were cross-sectional. The overall pooled prevalence of burnout among Ethiopian nurses was estimated to be 39% (95% CI: 27%-50%). CONCLUSIONS: Burnout affects two out of five nurses in Ethiopia. Therefore, effective interventions and strategies are required to reduce burnout among nurses.

Prevalence and factors associated with uncontrolled hypertension among adult hypertensive patients on follow-up at Northern Ethiopia, 2019: cross-sectional study.

INTRODUCTION: uncontrolled hypertension is a major risk factor for cardiovascular, renal, and cerebrovascular morbidities and mortalities. This study aims to assess the prevalence and factors associated with uncontrolled hypertension among adult hypertensive patients. METHODS: hospital-based cross-sectional study was conducted. Systematic random sampling technique was used to select 396 hypertensive patients. Respondents were interviewed and their medical charts were reviewed using pretested structured questionnaire. Bivariable logistic regression was employed to examine the crude associations between the outcome variable and determinant variables. This was followed by multivariable logistic regression analysis using those variables with P-value ≤ 0.25 in the bivariable analysis. RESULTS: of the total 396 hypertensive patients the prevalence of uncontrolled hypertension was found to be 48.6%. One fourth (26.1%), 231(59.1%), 289(73.9%), and 151(38.6%) hypertensive respondents were non adherent to anti-hypertensive medication, physical exercise, low salt diet, and weight management respectively. Age ≥50 years old (AOR = 2.33, 95%CI: 1.25, 4.35), non-adherence to anti-hypertensive medication, (AOR = 1.82 95%CI: 1.08, 3.04), non-adherence to physical exercise (AOR = 1.79 95%CI: 1.13, 2.83), non-adherence to low-salt diet (AOR = 1.98 95%CI: 1.18,3.31), and non-adherence to weight management (AOR = 2.06, 95%CI: 1.31, 3.23) were significantly associated with uncontrolled hypertension. CONCLUSION: the prevalence of uncontrolled hypertension was high. Older hypertensive patients, non-adherent to their medications, physical inactivity, non-adherent to low salt diet and non-adherent to weight management were more likely to have uncontrolled hypertension. Therefore, more effort should be dedicated to those identified modifiable risk factors to maximize blood pressure control.

The burden, admission, and outcomes of COVID-19 among asthmatic patients in Africa: protocol for a systematic review and meta-analysis.

BACKGROUND: Coronavirus disease 2019 outbreak is the first reported case in Wuhan, China in December 2019 and suddenly became a major global health concern. According to the European Centre for Disease Prevention and Control, on August 4, 2020 the reported cases of coronavirus disease 2019 were 18,456,952 cases worldwide, 11,691,229 recovered with 697,719 deaths. Evidence on Burden, admission and outcome of Coronavirus Disease in 2019 among Asthmatic patients has not been published in Africa. This research protocol will, therefore, be driven to conduct systematic review and meta-analysis of the Coronavirus Disease in 2019 burden, admission and outcome among Asthmatic patients in Africa. METHODS: All observational studies among Asthmatic patients in Africa and written without language limitation will be included. A search technique was applied using Databases (PubMed / MEDLINE, EMBASE, HINARI, Cochrane Library, World Health Organization COVID-19 database, Africa Wide Knowledge and Web of Science). Two independent authors carried out data extraction and assess the risk of bias using a predetermined and structured method of data collection. We will use random-effects to estimate the overall pooled burden, admission and outcome of COVID-19 Asthmatic patients in Africa. To assess possible publication bias, funnel plot test and Egger's test methods will be used. This systematic and meta-analysis review protocol will be reported based on the Preferred Reporting Items for Systematic reviews and Meta-Analysis protocol guidelines. DISCUSSION: The description will be used to show the COVID-19 distribution data by interest variables such as residence, setting, and person-level characteristics. The findings of this review will notify health care professionals about the burden, admission and outcome of COVID - 19 in asthmatic patient, while providing evidence to bring about the requisite improvements in clinical practice for asthmatic patients. SYSTEMATIC REVIEW REGISTRATION: This review is registered in the PROSPERO International Prospective Register of Systematic reviews with the registration number of CRD42020202049.

Magnitude and Its Associated Factors of Urinary Tract Infection among Adult Patients Attending Tigray Region Hospitals, Northern Ethiopia, 2019.

BACKGROUND: Urinary tract infection is a major public health problem in terms of morbidity and mortality worldwide. It ranks as the number one infection which leads to an antibiotic prescription after a physician's visit. However, there are limited studies done on UTI in Ethiopia. Hence, this study was aimed to assess the magnitude of urinary tract infection and its associated factors among adult patients attending hospitals of the Tigray region, Ethiopia. Methods and Material. A hospital-based cross-sectional study was conducted from April to May 2019. Systematic random sampling technique was used to select 472 participants from five randomly selected hospitals in Tigray region. A pretested structured questionnaire through face-to-face interview and patient chart review checklist was used to collect data. Data were analyzed by SPSS version 21. A binary logistic regression model was used to test the association between dependent and independent variables. RESULT: The magnitude of urinary tract infection was 86 (18.2%) (95% CI: 14.6%-21.6%). After adjustment of the independent variables, the significant factors associated with urinary tract infection were being female (AOR = 3.50; 95% CI: 1.88-6.51), urine passing frequency < five times in a day (AOR = 2.32; 95% CI: 1.08-4.96), having diabetes mellitus (AOR = 4.03; 95% CI: 1.69-9.63), history of urinary tract infection (AOR = 4.40; 95% CI: 2.31-8.39), <7 glasses of water intake per day (AOR = 2.16; 95% CI: 1.02-4.58), and history of urinary obstructive diseases (AOR = 2.67; 95% CI: 1.03-6.90). Conclusion and Recommendation. The magnitude of urinary tract infection was considerably high. The factors associated with urinary tract infection were sex, less urine passing frequency, diabetes mellitus, low water intake, history of urinary tract infection, and urinary obstructive diseases. Therefore, patients having DM, previous history of UTI, and urinary obstructive diseases should be routinely screened for urinary tract infection and provided with education on voiding urine at least five times a day and on increasing daily water intake.
