Abstract
BACKGROUND: The aim of these clinical standards is to aid the diagnosis and management of asthma in low-resource settings in low- and middle-income countries (LMICs).METHODS: A panel of 52 experts in the field of asthma in LMICs participated in a two-stage Delphi process to establish and reach a consensus on the clinical standards.RESULTS: Eighteen clinical standards were defined: Standard 1, Every individual with symptoms and signs compatible with asthma should undergo a clinical assessment; Standard 2, In individuals (>6 years) with a clinical assessment supportive of a diagnosis of asthma, a hand-held spirometry measurement should be used to confirm variable expiratory airflow limitation by demonstrating an acute response to a bronchodilator; Standard 3, Pre- and post-bronchodilator spirometry should be performed in individuals (>6 years) to support diagnosis before treatment is commenced if there is diagnostic uncertainty; Standard 4, Individuals with an acute exacerbation of asthma and clinical signs of hypoxaemia or increased work of breathing should be given supplementary oxygen to maintain saturation at 94-98%; Standard 5, Inhaled short-acting beta-2 agonists (SABAs) should be used as an emergency reliever in individuals with asthma via an appropriate spacer device for metered-dose inhalers; Standard 6, Short-course oral corticosteroids should be administered in appropriate doses to individuals having moderate to severe acute asthma exacerbations (minimum 3-5 days); Standard 7, Individuals having a severe asthma exacerbation should receive emergency care, including oxygen therapy, systemic corticosteroids, inhaled bronchodilators (e.g., salbutamol with or without ipratropium bromide) and a single dose of intravenous magnesium sulphate should be considered; Standard 8, All individuals with asthma should receive education about asthma and a personalised action plan; Standard 9, Inhaled medications (excluding dry-powder devices) should be administered via an appropriate spacer device in both adults and children. Children aged 0-3 years will require the spacer to be coupled to a face mask; Standard 10, Children aged <5 years with asthma should receive a SABA as-needed at step 1 and an inhaled corticosteroid (ICS) to cover periods of wheezing due to respiratory viral infections, and SABA as-needed and daily ICS from step 2 upwards; Standard 11, Children aged 6-11 years with asthma should receive an ICS taken whenever an inhaled SABA is used; Standard 12, All adolescents aged 12-18 years and adults with asthma should receive a combination inhaler (ICS and rapid onset of action long-acting beta-agonist [LABA] such as budesonide-formoterol), where available, to be used either as-needed (for mild asthma) or as both maintenance and reliever therapy, for moderate to severe asthma; Standard 13, Inhaled SABA alone for the management of patients aged >12 years is not recommended as it is associated with increased risk of morbidity and mortality. It should only be used where there is no access to ICS.The following standards (14-18) are for settings where there is no access to inhaled medicines. Standard 14, Patients without access to corticosteroids should be provided with a single short course of emergency oral prednisolone; Standard 15, Oral SABA for symptomatic relief should be used only if no inhaled SABA is available. Adjust to the individual's lowest beneficial dose to minimise adverse effects; Standard 16, Oral leukotriene receptor antagonists (LTRA) can be used as a preventive medication and is preferable to the use of long-term oral systemic corticosteroids; Standard 17, In exceptional circumstances, when there is a high risk of mortality from exacerbations, low-dose oral prednisolone daily or on alternate days may be considered on a case-by-case basis; Standard 18. Oral theophylline should be restricted for use in situations where it is the only bronchodilator treatment option available.CONCLUSION: These first consensus-based clinical standards for asthma management in LMICs are intended to help clinicians provide the most effective care for people in resource-limited settings.

Abstract
BACKGROUND The Enhancing Nutrition and Antenatal Infection Treatment (ENAT) intervention was implemented in Ethiopia to improve newborn birth weight (BW) by strengthening the contents and quality of antenatal care (ANC), especially point-of-care testing for maternal infections. This study examined the effect of the ENAT intervention on birth weight. METHODS We conducted a cluster randomized controlled trial of 22 clusters (health centers), randomized equally between 11 intervention and 11 control clusters. This study enrolled and followed pregnant women from ANC booking to the end of pregnancy or loss to follow-up. The primary outcome was mean BW, and the incidence of low birth weight (LBW) was the secondary outcome. We presented univariate comparisons of outcomes between the intervention and control arms for mean BW and LBW. Multilevel analyses using random effects models were performed to adjust for clustering and individual-level covariates. RESULTS We enrolled and followed up 4,868 and 4,821 pregnant women in the intervention and control arms, respectively, from March 2021-July 2022. During follow-up, 3445 pregnant women in the intervention and 3192 in the control delivered in the health centers, and BW measurements of their babies were recorded within 48 h. The mean BW was 3,152 g (standard deviation (SD) = 339.8 g) in the intervention and 3,044 g (SD = 353.8 g) in the control arms (mean difference, 108 g; 95% confidence interval (CI): 91.3-124.6; P = 0.000). Adjusting for clustering and several covariates, the mean BW remained significantly higher in the intervention arm than in the control arm (adjusted ß coef., 114.3; p = 0.011). The incidence of LBW was 4.7% and 7.3% in the intervention and control arms, respectively. The adjusted risk of LBW was significantly lower by 36% in the intervention arm than in the control arm (adjusted relative risk, 0.645; p = 0.027). CONCLUSION This study provided sufficient evidence of the effectiveness of the ENAT intervention in improving birth weight in the study population. The intervention demonstrated that an increase in birth weight can be attained by availing point-of-care testing, strengthening infection prevention, and maternal nutrition within the ANC platform of public health facilities in a low-income setting.

Abstract
BACKGROUND The optimal anastomotic techniques in esophagectomy to minimize rates of anastomotic leakage and conduit necrosis are not known. The aim of this study was to assess whether the anastomotic technique was associated with anastomotic failure after esophagectomy in the international Oesophago-Gastric Anastomosis Audit cohort. METHODS This prospective observational multicenter cohort study included patients undergoing esophagectomy for esophageal cancer over 9 months during 2018. The primary exposure was the anastomotic technique, classified as handsewn, linear stapled, or circular stapled. The primary outcome was anastomotic failure, namely a composite of anastomotic leakage and conduit necrosis, as defined by the Esophageal Complications Consensus Group. Multivariable logistic regression modeling was used to identify the association between anastomotic techniques and anastomotic failure, after adjustment for confounders. RESULTS Of the 2238 esophagectomies, the anastomosis was handsewn in 27.1%, linear stapled in 21.0%, and circular stapled in 51.9%. Anastomotic techniques differed significantly by the anastomosis sites (P < .001), with the majority of neck anastomoses being handsewn (69.9%), whereas most chest anastomoses were stapled (66.3% circular stapled and 19.3% linear stapled). Rates of anastomotic failure differed significantly among the anastomotic techniques (P < .001), from 19.3% in handsewn anastomoses, to 14.0% in linear stapled anastomoses, and 12.1% in circular stapled anastomoses. This effect remained significant after adjustment for confounding factors on multivariable analysis, with an odds ratio of 0.63 (95% CI, 0.46-0.86; P = .004) for circular stapled versus handsewn anastomosis. However, subgroup analysis by anastomosis site suggested that this effect was predominantly present in neck anastomoses, with anastomotic failure rates of 23.2% versus 14.6% versus 5.9% for handsewn versus linear stapled anastomoses versus circular stapled neck anastomoses, compared with 13.7% versus 13.8% versus 12.2% for chest anastomoses. CONCLUSIONS Handsewn anastomoses appear to be independently associated with higher rates of anastomotic failure compared with stapled anastomoses. However, this effect seems to be largely confined to neck anastomoses, with minimal differences between techniques observed for chest anastomoses. Further research into standardization of anastomotic approach and techniques may further improve outcomes.

Abstract
Abstract
Background
Textbook outcome has been proposed as a tool for the assessment of oncological surgical care. However, an international assessment in patients undergoing oesophagectomy for oesophageal cancer has not been reported. This study aimed to assess textbook outcome in an international setting.
Methods
Patients undergoing curative resection for oesophageal cancer were identified from the international Oesophagogastric Anastomosis Audit (OGAA) from April 2018 to December 2018. Textbook outcome was defined as the percentage of patients who underwent a complete tumour resection with at least 15 lymph nodes in the resected specimen and an uneventful postoperative course, without hospital readmission. A multivariable binary logistic regression model was used to identify factors independently associated with textbook outcome, and results are presented as odds ratio (OR) and 95 per cent confidence intervals (95 per cent c.i.).
Results
Of 2159 patients with oesophageal cancer, 39.7 per cent achieved a textbook outcome. The outcome parameter ‘no major postoperative complication’ had the greatest negative impact on a textbook outcome for patients with oesophageal cancer, compared to other textbook outcome parameters. Multivariable analysis identified male gender and increasing Charlson comorbidity index with a significantly lower likelihood of textbook outcome. Presence of 24-hour on-call rota for oesophageal surgeons (OR 2.05, 95 per cent c.i. 1.30 to 3.22; P = 0.002) and radiology (OR 1.54, 95 per cent c.i. 1.05 to 2.24; P = 0.027), total minimally invasive oesophagectomies (OR 1.63, 95 per cent c.i. 1.27 to 2.08; P < 0.001), and chest anastomosis above azygous (OR 2.17, 95 per cent c.i. 1.58 to 2.98; P < 0.001) were independently associated with a significantly increased likelihood of textbook outcome.
Conclusion
Textbook outcome is achieved in less than 40 per cent of patients having oesophagectomy for cancer. Improvements in centralization, hospital resources, access to minimal access surgery, and adoption of newer techniques for improving lymph node yield could improve textbook outcome.

Abstract
BACKGROUND The complexity of oesophageal surgery and the significant risk of morbidity necessitates that oesophagectomy is predominantly performed by a consultant surgeon, or a senior trainee under their supervision. The aim of this study was to determine the impact of trainee involvement in oesophagectomy on postoperative outcomes in an international multicentre setting. METHODS Data from the multicentre Oesophago-Gastric Anastomosis Study Group (OGAA) cohort study were analysed, which comprised prospectively collected data from patients undergoing oesophagectomy for oesophageal cancer between April 2018 and December 2018. Procedures were grouped by the level of trainee involvement, and univariable and multivariable analyses were performed to compare patient outcomes across groups. RESULTS Of 2232 oesophagectomies from 137 centres in 41 countries, trainees were involved in 29.1 per cent of them (n = 650), performing only the abdominal phase in 230, only the chest and/or neck phases in 130, and all phases in 315 procedures. For procedures with a chest anastomosis, those with trainee involvement had similar 90-day mortality, complication and reoperation rates to consultant-performed oesophagectomies (P = 0.451, P = 0.318, and P = 0.382, respectively), while anastomotic leak rates were significantly lower in the trainee groups (P = 0.030). Procedures with a neck anastomosis had equivalent complication, anastomotic leak, and reoperation rates (P = 0.150, P = 0.430, and P = 0.632, respectively) in trainee-involved versus consultant-performed oesophagectomies, with significantly lower 90-day mortality in the trainee groups (P = 0.005). CONCLUSION Trainee involvement was not found to be associated with significantly inferior postoperative outcomes for selected patients undergoing oesophagectomy. The results support continued supervised trainee involvement in oesophageal cancer surgery.

Abstract
BACKGROUND Clean Cut is an adaptive, multimodal programme to identify improvement opportunities and safety changes in surgery by enhancing outcomes surveillance, closing gaps in surgical infection prevention standards, and strengthening underlying processes of care. Surgical-site infections (SSIs) are common in low-income countries, so this study assessed a simple intervention to improve perioperative infection prevention practices in one. METHODS Clean Cut was implemented in five hospitals in Ethiopia from August 2016 to October 2018. Compliance data were collected from the operating room focused on six key perioperative infection prevention standards. Process-mapping exercises were employed to understand barriers to compliance and identify locally driven improvement opportunities. Thirty-day outcomes were recorded on patients for whom intraoperative compliance information had been collected. RESULTS Compliance data were collected from 2213 operations (374 at baseline and 1839 following process improvements) in 2202 patients. Follow-up was completed in 2159 patients (98·0 per cent). At baseline, perioperative teams complied with a mean of only 2·9 of the six critical perioperative infection prevention standards; following process improvement changes, compliance rose to a mean of 4·5 (P < 0·001). The relative risk of surgical infections after Clean Cut implementation was 0·65 (95 per cent c.i. 0·43 to 0·99; P = 0·043). Improved compliance with standards reduced the risk of postoperative infection by 46 per cent (relative risk 0·54, 95 per cent c.i. 0·30 to 0·97, for adherence score 3-6 versus 0-2; P = 0·038). CONCLUSION The Clean Cut programme improved infection prevention standards to reduce SSI without infrastructure expenses or resource investments.

Abstract
BACKGROUND No evidence currently exists characterising global outcomes following major cancer surgery, including esophageal cancer. Therefore, this study aimed to characterise impact of high income countries (HIC) versus low and middle income countries (LMIC) on the outcomes following esophagectomy for esophageal cancer. METHOD This international multi-center prospective study across 137 hospitals in 41 countries included patients who underwent an esophagectomy for esophageal cancer, with 90-day follow-up. The main explanatory variable was country income, defined according to the World Bank Data classification. The primary outcome was 90-day postoperative mortality, and secondary outcomes were composite leaks (anastomotic leak or conduit necrosis) and major complications (Clavien-Dindo Grade III - V). Multivariable generalized estimating equation models were used to produce adjusted odds ratios (ORs) and 95% confidence intervals (CI95%). RESULTS Between April 2018 to December 2018, 2247 patients were included. Patients from HIC were more significantly older, with higher ASA grade, and more advanced tumors. Patients from LMIC had almost three-fold increase in 90-day mortality, compared to HIC (9.4% vs 3.7%, p < 0.001). On adjusted analysis, LMIC were independently associated with higher 90-day mortality (OR: 2.31, CI95%: 1.17-4.55, p = 0.015). However, LMIC were not independently associated with higher rates of anastomotic leaks (OR: 1.06, CI95%: 0.57-1.99, p = 0.9) or major complications (OR: 0.85, CI95%: 0.54-1.32, p = 0.5), compared to HIC. CONCLUSION Resections in LMIC were independently associated with higher 90-day postoperative mortality, likely reflecting a failure to rescue of these patients following esophagectomy, despite similar composite anastomotic leaks and major complication rates to HIC. These findings warrant further research, to identify potential issues and solutions to improve global outcomes following esophagectomy for cancer.

Abstract
Walia Ibex Capra walie is an endemic and endangered species residing in Simien Mountains National Park, Ethiopia. It has shifted its range within the Park in the last decade, and in this study our main objective was to provide information on their feeding ecology to inform recovery goals. We used a scan sampling method to collect foraging information during October 2009 to November 2011. Our observations suggest a diverse diet of more than 28 species of grasses, forbs, and shrubs. The most commonly used plants were Festuca sp., Lobelia rhynchopetalum, Helichrysum citrispinum, and Helichrysum horridum. Walia Ibex were active in feeding before and after mid-day, and time spent feeding was the highest compared with other diurnal activities. The percentage of time spent feeding on major plant species did not differ between wet and dry seasons (p> 0.05). Walia Ibex, however, tended to spend more time browsing than grazing. The generalist nature of foraging behaviour in Walia Ibex most likely contributes to complaints from the local people who witness Walia Ibex raiding crops cultivated in and around the Park. Thus, the contribution of crop raiding to the shifts in the species’ range towards higher altitudes at Sebatminch within Simien Mountains National Park emphasizes the need to consider foraging ecology as community-based conservation efforts are developed to support Walia Ibex in the Park.

Abstract
BACKGROUND A baseline assessment of surgical capacity is recommended as a first-step to surgical system strengthening in order to inform national policy. In Ethiopia, the World Health Organization's Tool for Situational Analysis (WHO SAT) was adapted to assess surgical, obstetric, and anesthesia capacity as part of a national initiative: Saving Lives Through Safe Surgery (SaLTS). This study describes the process of adapting this tool and initial results. MATERIALS AND METHODS The new tool was used to evaluate fourteen hospitals in the Southern Nations, Nationalities, and People's Region of Ethiopia between February and March 2017. Two analytic methods were employed. To compare this data to international metrics, the WHO Service Availability and Readiness Assessment (SARA) framework was used. To assess congruence with national policy, data was evaluated against Ethiopian SaLTS targets. RESULTS Facilities had on average 62% of SARA items necessary for both basic surgery and comprehensive surgery. Primary, general, and specialized facilities offered on average 84%, 100%, and 100% of SARA basic surgeries, and 58%, 73% and 90% of SARA comprehensive surgeries, respectively. An average of 68% of SaLTS primary surgeries were available at primary facilities, 83% at general facilities, and 100% at specialized facilities. General and specialized hospitals offered an average of 80% of SaLTS general surgeries, while one specialized hospital offered 38% of SaLTS specialized surgeries. CONCLUSION While the modified SaLTS Tool provided evaluation against Ethiopian national benchmarks, the resultant assessment was much lengthier than standard international tools. Analysis of results using the SARA framework allowed for comparison to global standards and provided insight into essential parts of the tool. An assessment tool for national surgical policy should maintain internationally comparable metrics and incorporation into existing surveys when possible, while including country-specific targets.

Abstract
Background Emergency and essential surgical, obstetric and anaesthesia (SOA) care are now recognized components of universal health coverage, necessary for a functional health system. To improve surgical care at a national level, strategic planning addressing the six domains of a surgical system is needed. This paper details a process for development of a national surgical, obstetric and anaesthesia plan (NSOAP) based on the experiences of frontline providers, Ministry of Health officials, WHO leaders, and consultants. Methods Development of a NSOAP involves eight key steps: Ministry support and ownership; situation analysis and baseline assessments; stakeholder engagement and priority setting; drafting and validation; monitoring and evaluation; costing; governance; and implementation. Drafting a NSOAP involves defining the current gaps in care, synthesizing and prioritizing solutions, and providing an implementation and monitoring plan with a projected cost for the six domains of a surgical system: infrastructure, service delivery, workforce, information management, finance and governance. Results To date, four countries have completed NSOAPs and 23 more have committed to development. Lessons learned from these previous NSOAP processes are described in detail. Conclusion There is global movement to address the burden of surgical disease, improving quality and access to SOA care. The development of a strategic plan to address gaps across the SOA system systematically is a critical first step to ensuring countrywide scale‐up of surgical system‐strengthening activities.

Abstract
Background In 2015, six indicators were proposed to evaluate global progress towards access to safe, affordable and timely surgical and anaesthesia care. Although some have been adopted as core global health indicators, none has been evaluated systematically. The aims of this study were to assess the availability, comparability and utility of the indicators, and to present available data and updated estimates. Methods Nationally representative data were compiled for all World Health Organization (WHO) member states from 2010 to 2016 through contacts with official bodies and review of the published and grey literature, and available databases. Availability, comparability and utility were assessed for each indicator: access to timely essential surgery, specialist surgical workforce density, surgical volume, perioperative mortality, and protection against impoverishing and catastrophic expenditure. Where feasible, imputation models were developed to generate global estimates. Results Of all WHO member states, 19 had data on the proportion of the population within 2h of a surgical facility, 154 had data on workforce density, 72 reported number of procedures, and nine had perioperative mortality data, but none could report data on catastrophic or impoverishing expenditure. Comparability and utility were variable, and largely dependent on different definitions used. There were sufficient data to estimate that worldwide, in 2015, there were 2 038 947 (i.q.r. 1 884 916–2 281 776) surgeons, obstetricians and anaesthetists, and 266·1 (95 per cent c.i. 220·1 to 344·4) million operations performed. Conclusion Surgical and anaesthesia indicators are increasingly being adopted by the global health community, but data availability remains low. Comparability and utility for all indicators require further resolution.

Abstract
OBJECTIVE Immunotherapy using vitamin D (vitD3 ) and phenylbutyrate (PBA) may support standard drug regimens used to treat infectious diseases. We investigated if vitD3 + PBA enhanced clinical recovery from pulmonary tuberculosis (TB). METHODS A randomized controlled trial was conducted in Addis Ababa, Ethiopia. Patients with smear-positive or smear-negative TB received daily oral supplementation with 5000 IU vitD3 and 2 × 500 mg PBA or placebo for 16 weeks, together with 6-month chemotherapy. Primary end-point: reduction of a clinical composite TB score at week 8 compared with baseline using modified intention-to-treat (mITT, n = 348) and per-protocol (n = 296) analyses. Secondary end-points: primary and modified TB scores (week 0, 4, 8, 16, 24), sputum conversion, radiological findings and plasma 25(OH)D3 concentrations. RESULTS Most subjects had low baseline plasma 25(OH)D3 levels that increased gradually in the vitD3 + PBA group compared with placebo (P < 0.0001) from week 0 to 16 (mean 34.7 vs. 127.4 nmol L-1 ). In the adjusted mITT analysis, the primary TB score was significantly reduced in the intervention group at week 8 (-0.52, 95% CI -0.93, -0.10; P = 0.015) while the modified TB score was reduced at week 8 (-0.58, 95% CI -1.02, -0.14; P = 0.01) and 16 (-0.34, 95% CI -0.64, -0.03; P = 0.03). VitD3 + PBA had no effect on longitudinal sputum-smear conversion (P = 0.98). Clinical adverse events were more common in the placebo group (24.3%) compared with the vitD3 + PBA group (12.6%). CONCLUSION Daily supplementation with vitD3 + PBA may ameliorate clinical TB symptoms and disease-specific complications, while the intervention had no effect on bacterial clearance in sputum.

Abstract
Oil sand operations in Alberta, Canada will eventually include returning treated process-affected waters to the environment. Organic constituents in oil sand process-affected water (OSPW) represent complex mixtures of nonionic and ionic (e.g., naphthenic acids) compounds, and compositions can vary spatially and temporally, which has impeded development of water quality benchmarks. To address this challenge, it was hypothesized that solid phase microextraction fibers coated with polydimethylsiloxane (PDMS) could be used as a biomimetic extraction (BE) to measure bioavailable organics in OSPW. Organic constituents of OSPW were assumed to contribute additively to toxicity, and partitioning to PDMS was assumed to be predictive of accumulation in target lipids, which were the presumed site of action. This method was tested using toxicity data for individual model compounds, defined mixtures, and organic mixtures extracted from OSPW. Toxicity was correlated with BE data, which supports the use of this method in hazard assessments of acute lethality to aquatic organisms. A species sensitivity distribution (SSD), based on target lipid model and BE values, was similar to SSDs based on residues in tissues for both nonionic and ionic organics. BE was shown to be an analytical tool that accounts for bioaccumulation of organic compound mixtures from which toxicity can be predicted, with the potential to aid in the development of water quality guidelines.

Abstract
Walia ibex (Capra walie) is an endangered and endemic species restricted to the Simien Mountains National Park, Ethiopia. Recent expansion of human populations and livestock grazing in the park has prompted concerns that the range and habitats used by walia ibex have changed. We performed observations of walia ibex, conducted pellet counts of walia ibex and livestock, and measured vegetation and classified habitat characteristics at sample points during wet and dry seasons from October 2009 to November 2011. We assessed the effect of habitat characteristics on the presence of pellets of walia ibex, and then used a spatial model to create a predictive map to determine areas of high potential to support walia ibex. Rocky and shrubby habitats were more preferred than herbaceous habitats. Pellet distribution indicated that livestock and walia ibex were not usually found at the same sample point (i.e. 70% of quadrats with walia pellets were without livestock droppings; 73% of quadrats with livestock droppings did not have walia pellets). The best model to describe probability of presence of walia pellets included effects of herb cover (β = 0.047), shrub cover (β = 0.030), distance to cliff (β = –0.001), distance to road (β = 0.001), and altitude (β = 0.004). Walia ibexes have shifted to the eastern, steeper areas of the park, appearing to coincide with the occurrence of more intense, human–related activities in lowlands. Our study shows the complexities of managing areas that support human populations while also serving as a critical habitat for species of conservation concern.

Abstract
Over the period 1998-2001 women attending Jimma hospital (southwest Ethiopia) with cervical dysplasia were screened for human papillomavirus (HPV), identifying a prevalence of 67.1% in this population. High-risk HPV types 16 (55.7%), 18 (8.2%), 56 (8.2%), 45 (4.1%), 39 (2.5%), 52 (1.6%), 31 (1.6%), 35 (1.6%), 58 (0.8%), 33 (0.8%), 59 (0.8%) caused severe pathology as single/multiple infection. Strategies need to be envisioned for vaccinating children, young women prior to first sexual contact and preventive screening of HPV high-risk types.

Abstract
OBJECTIVES To describe the clinical profile and determine the risk factors associated with perforation of appendix in children under 13 years of age. DESIGN A retrospective review of charts of children admitted for appendicitis between the year 1999 to 2000. SETTING Department of Paediatrics and Child Health, Tikur Anbessa Specialised Hospital, Addis Ababa University, Addis Ababa, Ethiopia. SUBJECTS A total of 147 children under the age of 13 years admitted for acute appendicitis. RESULTS A total of 147 cases were analysed. The mean age was 9.3 years and appendicitis occurred more commonly among males. Factors independently found to be predictors of perforation by univariate analysis were: age <10 years, duration of illness for over 24 hours, history of treatment elsewhere before arrival to TAH, generalised abdominal tenderness, rebound tenderness and/or rigidity, hypoactive and/or absent bowel sound, RLQ mass, leukocytosis with neutrophilia and presence of complications. However, none of these was retained as significant factors in the multiple logistic regression analysis. CONCLUSION There are many factors that are associated with perforation but there is no single factor that independently predicted perforation of appendicitis. Delay in intervention due to late presentation to hospital is an important preventable factor.

Abstract
Abstract
Forest productivity may be enhanced by satisfying the nutrient requirement of trees through fertilization. A field experiment was designed to study the response of densely stocked 1-yr-old loblolly pine to nitrogen and phosphorus in the presence of applied K on a Beauregard silt loam soil (fine-silty, siliceous, thermic Plinthaquic Paleudults) of the Gulf Coastal Plain. The continuous function design with three replications was used. Fertilizer P rate was based on the P adsorption characteristics of the soil. After 1 yr of growth, the response variables: height; total aboveground dry matter; foliage and wood dry matter; diameter at ground level; and N, P, and K contents were related to the rate of N and P applied by quadratic models with response surface methodology. The lack-of-fit test showed that the quadratic model was adequate in explaining the relationship between N and P applied and all the response variables except height. Fertilization with N alone on this soil had a depressing effect on yield. Growth and nutrient uptake were enhanced when both N and P were applied. The predicted N and P levels that would give maximum growth were beyond the rates of N and P tested, indicating that more time should be given to observe the full response. South. J. Appl. For. 27(3):180–189.

Abstract
Ethiopia has been engaged in expanding immunization services against the six childhood diseases since 1980. According to plans set at the beginning of the program, the country should have achieved universal child immunization by now. However, the child immunization coverage has never reached the level that is desired to curtail disease transmission and to reduce the morbidity burden associated with the target diseases. This study used the potential of social science research methods in understanding social, cultural, political and economic factors that influence the efficiency and effectiveness of immunization programs in the Ethiopian context. A better understanding of these factors is believed to improve the quality and sustainability of immunization programs. This research focused on relevant issues at micro- and macro-levels. The study basically utilized qualitative research methods involving multiple data collection tools and information sources. Factors related to acceptors, immunization service providers and organization of health services that influence the successful implementation and sustainability of the immunization program in the Ethiopian context are identified and discussed. Strengthening efforts to improve technical capacity of service providers, increasing social mobilization activities, instituting quality assurance schemes and improving management of resources (human, finance and material) are among the major recommendations.

Abstract
BACKGROUND Though bottle feeding is known to be hazardous either due to over-dilution of the supplement or faulty hygienic techniques during its preparation, especially in areas where general sanitation is poor, very little attention has been paid to it in developing countries. OBJECTIVE To determine the extent of bottle use in child feeding and the factors associated with its use in rural communities. DESIGN Community based cross-sectional study. PATIENTS One thousand five hundred and thirty six children, aged 0-23 months and their mothers were included in the study. RESULTS The overall prevalence of bottle feeding was 11.3%. Out of the 174 children who were bottle fed, only 11(6.3%) were exclusively on it. Residence, maternal education and occupation were significantly associated with the practice of bottle feeding in the crude analysis and after adjusting for parental and child characteristics (p < 0.05). CONCLUSION The extent of bottle feeding in the studied communities is generally high, with a higher rate among town women, a trend which was seen in the developed world at the beginning of the century. Improvement in maternal and child health services including education on child feeding are recommended.

Abstract
The respiratory effects of dusts in different sections of yarn, cement, and cigarette factories were studied in 211 nonsmoking male and female workers aged 21-57 years. The controls used were 211 healthy nonsmoking and nonexposed male and female subjects aged 20-57 years from the general population. Forced vital capacity (FVC), forced expiratory volume in 1 sec (FEV1), FEV1/FVC ratio, forced expiratory flow (FEF200-1,200 ml), forced mid-expiratory flow (FMF25-75%) and peak expiratory flow rate (PEFR) were recorded in all subjects with and without respiratory symptoms. Taking exposures to all dusts of different concentrations together, it was found that the frequency of respiratory illness was greater among exposed workers (40.5% in males, 36% in females) than it was among controls (21.6% in males, 18% in females). In exposed subjects, the symptom prevalence was only 4.5% higher in males than in females. The mean lung function indices, including FEV1, FEV1%, FEF200-1,200 ml, FMF25-75%, and PEFR, in subjects exposed to all dusts in general decreased markedly, with dust concentration being more important than duration of exposure, and FMF being affected slightly more consistently. About 38.4% of the dust-exposed subjects developed corresponding respiratory illnesses including chronic cough (24.7%), chronic bronchitis (21.8%) and bronchial asthma (24.2%). The respective control values were 9.0%, 9.5%, and 8.5%. Exposure to different occupational dusts resulted in the development of respiratory illness with different rates of prevalence. The effects of exposure to cotton and cement dusts on respiratory health of exposed subjects were relatively more significant (p < 0.001) than that of exposure to tobacco dust (p < 0.05).

Abstract
A descriptive cross sectional study on mothers' knowledge and practice related to weaning was conducted in Butajira in 1994. A total of 1,543 mother-child pair were included in the study, of which 1,052 (68%) children were on weaning diet and 491 (32%) were exclusively breast feeding. Among children who were already weaned, 40% were reported to have been started on weaning food at the age of 4-6 months. Of the children who were reported to be exclusively breast feeding, 34% were beyond the age of 7 months. The most commonly used weaning food were cow's milk, adult food, sorghum water and cereal gruel in descending order and the most important reasons for mothers to start weaning were reduction of the amount of breast milk and mothers' belief that the child is at the right age to start weaning food. The majority of the mothers used "swallow or suffocate" method in feeding their children, though cups and bottles were also mentioned as important feeding methods. The study demonstrated the presence of inappropriate weaning practice in the area which needs appropriate intervention.

Abstract
There is a medical need for an agent with the positive effects of estrogen on bone and the cardiovascular system, but without the negative effects on reproductive tissue. Raloxifene (LY139481 HCI) is a benzothiophene derivative that binds to the estrogen receptor and inhibits the effects of estrogen on the uterus. In an ovariectomized (OVX) rat model we investigated the effects of raloxifene on bone loss (induced by estrogen deficiency), serum lipids, and uterine tissue. After oral administration of raloxifene for 5 wk (0.1-10 mg/kg per d) to OVX rats, bone mineral density in the distal femur and proximal tibia was significantly greater than that observed in OVX controls (ED50 of 0.03-0.3 mg/kg). Serum cholesterol was lower in the raloxifene-treated animals, which had a minimal effective dose of 0.1 mg/kg and an approximate oral ED50 of 0.2 mg/kg. The effects of raloxifene on bone and serum cholesterol were comparable to those of a 0.1-mg/kg per d oral dose of ethynyl estradiol. Raloxifene diverged dramatically from estrogen in its lack of significant estrogenic effects on uterine tissue. Ethynyl estradiol produced a marked elevation in a number of uterine histologic parameters (e.g., epithelial cell height, stromal eosinophilia). These data suggest that raloxifene has promise as an agent with beneficial bone and cardiovascular effects in the absence of significant uterine effects.

Abstract
It has been shown that in experiments where a negative feed-back method has been used, triiodothyronine and beta-adrenomimetic isopropylnoradrenaline exert a significant influence on the work of the whole system of thermoregulation in white rats. This is observed in an upward displacement of the "set-point" temperature.

Abstract
Cases of malnutrition-related diabetes mellitus conforming to the description of the protein deficient pancreatic diabetes type in Ethiopian patients were compared with Type 1 (insulin-dependent) and Type 2 (non-insulin-dependent) diabetic. Fourteen of 39 malnutrition-related diabetes mellitus patients had fat malabsorption compared with only two of ten Type 1 diabetic patients and one of nine control subjects. Xylose absorption was normal favouring a pancreatic cause for the malabsorption. Plasma C-peptide during oral glucose tolerance test was significantly lower than that in Type 2 diabetic patients and normal control subjects (p less than 0.01 to 0.001) and was also consistently but not significantly higher than in Type 1 diabetic patients. Glucagon secretion patterns were similar in malnutrition-related and Type 1 diabetic patients. Of 23 new malnutrition-related diabetic patients treated with glibenclamide after nutritional rehabilitation and insulin treatment, only three responded, 14 were unresponsive but remained ketosis free for over eight days while another six developed ketoacidosis or significant ketonuria within two to six days during the trial. Sixteen unselected Type 1 diabetic patients who discontinued their insulin therapy all developed frank ketoacidosis after a mean of 5.5 days. The similarity of the malnutrition-related and Type 1 diabetes mellitus in age of onset, insulin requirement for diabetic control and appearance of ketosis-proneness in some cases, together with the similarity of C-peptide and glucagon secretion patterns suggest that the protein deficient pancreatic diabetes variant of malnutrition-related diabetes mellitus may be Type 1 diabetes mellitus modified by the background of malnutrition rather than an aetiologically separate entity.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The macroeconomic difficulties facing the developing countries are having a direct impact on these countries' public health programs. Reduced budgets and rising demands for health care are forcing health ministries to either cut back on already inadequate health care services or identify alternative sources of revenue. This article describes and analyzes a set of experiments designed and implemented by the Sudan's Central Province that have effectively raised the operating budget of the regional health ministry. The seven experiments encompass imposition of fees, cost containment efforts, and local taxes earmarked for health. Together, the revenue generating efforts have improved the efficiency of service delivery, ensured more efficient resource allocation, raised much needed revenue for the health system, and honored the government's commitment to make free health care available to the Sudanese population.
