Malaria remains a major public health problem causing mortality and morbidity in tropical and subtropical countries. A cross-sectional study was carried out to determine malaria prevalence and its clinical pattern during malaria season in Yemen. Blood samples were collected from 511 patients with fever who voluntary participated in this study, of them 268 were males and 242 females. Malaria was screened using Giemsa-stained thick and thin blood films. Clinical profile was recorded through physical and laboratory examinations and biodata were collected by pre-tested standard questionnaire. The overall prevalence was 15.3%. Three malaria species (Plasmodium falciparum, Plasmodium vivax and Plasmodium malarae) were detected with the predominance of P. falciparum (83.33%). People living in the rural areas had higher infection rate compared to urban areas (p<0.005). Children were at higher risk of developing severe malaria compared to adults (p<0.05). Severe anaemia, respiratory distress, jaundice, convulsion and bleeding were more apparent among younger age groups of malaria cases compared to older children. The study indicates that malaria is still a public health problem with children being at high risk of developing severe malaria which may lead to death.

BACKGROUND/AIMS: The safety of the human body is maintained by effective monitoring of the mucosal surface integrity and protection against potentially harmful compounds. This function of the gut called intestinal barrier function can be affected by cholestasis and the absence of bile in the intestinal lumen. We aimed to determine whether the gut barrier integrity is impaired in infants with cholestasis by evaluation of the intestinal fatty acid binding proteins (I-FABP) and ileal bile acid binding protein (I-BABP) as markers of intestinal epithelial cell damage and plasma D-lactate level as a marker of gut wall permeability. METHODS: This case-control study included 53 infants with cholestasis and 29 controls. Serum levels of I-FABP, I-BABP, and D-lactate were measured in all subjects. RESULTS: Both groups of patients with neonatal hepatitis and biliary atresia showed significantly higher levels of I-FABP and I-BABP than the controls. There were no differences in the serum D-lactate level between the cases and controls. There was no difference between the two groups of patients (I and II) regarding any of the parameters studied. No significant correlations between serum levels of I-FABP, I-BABP, or D-lactate and total or direct bilirubin levels were found in the cholestatic infants. CONCLUSIONS: The intestinal epithelial barrier integrity is breached nearly in all parts of the intestine in infants with cholestasis. Further research is recommended to determine the impact of this finding on the management of these infants. The relationship between physical intestinal barrier damage and its functional failure remains subject for further research.

INTRODUCTIONThe failure of a humeral fracture to unite after surgical treatment may be due to many factors. When there are additional complications of infection, treatment by conventional methods of internal fixation becomes very difficult.

MATERIALS AND METHODSWe treated 8 infected non-union of diaphyseal fracture of the humerus by the Orthofix external fixator. All had previous surgical treatment. Non-union followed plating in 6 cases and in 2 cases after the external fixator. All patients had pain, at least one sinus discharging pus and severe functional impairment of the affected arm. There were 6 men and 2 women with a mean age 40.6 years.

RESULTSBone union was achieved in all cases. The mean time to union was 4.5 months (range, 2 to 8). Patients expressed high levels of satisfaction with the outcome, despite relatively modest improvement in pain and function, mainly because of long standing infection and intractable non-union. There were no major pin tract problems requiring the removal of the Schanz screws. Radial nerve palsy developed in 1 patient who recovered spontaneously. No patient required an additional bone grafting procedure.

CONCLUSIONThe use of the Orthofix external fixator without bone grafting was successful in the treatment of infected non-union of the humeral shaft. It shortened the duration of hospitalisation and immobilisation with moderate functional recovery.

Introduction
Whereas the numbers of new HIV infections and deaths due to AIDS have been reduced or stabilized, they remain high in sub-Saharan Africa. To further control the generalized epidemics and their consequences, countries have continued strengthening their programs to prevent new infections and deaths: however, program outcomes and impact at the national level are not well understood. The purpose of the review was to describe the country-level outcomes and impact of HIV/AIDS programs in eight sub-Saharan African countries in order to highlight future action agenda to meet universal access and policies related to Millennium Development Goals (MDGs).
Methods
The review used 16 of the 25 program outcome and impact indicators prescribed by the United Nations General Assembly Special Session (UNGASS). The review reported on the percentages accomplished by each country in their programs, categorized these figures into high (80% and higher), moderate (50-79%) and low (below 50%), and highlighted the domains in which outcomes and impact were high.
Results
Across countries, with the exception of Tanzania, programs had achieved nearly universal or universal outcomes and impact, but their coverage was limited to 2-5 program domains. Moreover, in domains with multiple target groups, such as in the provision of antiretroviral therapy and in the promotion and distribution of condom use, the programs were unable to produce high-end results for the affected populations. To further reduce their infections and deaths and to advance towards universal access and MDGs, countries must make their program outcomes and impact comprehensive and equitable.
Conclusion
Almost all national programs have high level accomplishments, but they must broaden their domain and audience coverage to further control the generalized epidemics and deaths in the eight countries. National responses must collect and analyze all the UNGASS data systematically and regularly in order to determine current HIV/AIDS knowledge and behaviors, ascertain program effects, and inform future actions.

As a synthetic analog of codeine, tramadol is often prescribed to treat mild to moderate pains. This study was designed to estimate and compare the histological effect of tramadol on testes of both juvenile and adult male albino mice. A total number of 40 healthy male albino mice were classified into two main groups as follows: group I (juvenile group, includes 20 mice aged three weeks) subdivided equally into group Ia (control group received isotonic saline) and group Ib (tramadoltreated group received 40 mg/kg/d tramadol orally for 30 days); group II (adult group, includes 20 mice aged two months) subdivided equally into group IIa (control group received isotonic saline) and group IIb (tramadol-treated group). Juvenile and adult tramadol-treated groups showed numerous testicular changes, including blood vessels congestion, widening of intercellular spaces, vacuolization in interstitial tissues, luminal germ cells exfoliation, and increased expression of caspase-3 that indicated cellular apoptosis. In the ultrastructural examination, spermatogenic cells degenerated with the frequent appearance of apoptotic cells. Sertoli cells showed vacuolations, large lipid droplets, and disrupted intercellular cell junctions.These observed testicular changes were markedly observed in the juvenile group. Testicular abnormalities and apoptotic changes can be caused by tramadol administration. These abnormalities are more common in juvenile mice.

Background: The treatment of adult Burkitt lymphoma with pediatric-based chemotherapy protocols usually results in high cure rates, although with significant toxicity. We report our experience with the Cancer and Leukemia Group B1002 (CALGB 1002) protocol. Methods: The files of adult patients diagnosed with Burkitt lymphoma and treated with the CALGB 1002 protocol at King Hussein Cancer Center between 2008 and 2017 were reviewed.Baseline demographics, clinical laboratory features, treatment details, and responses were collected. The correlations between clinical and laboratory variables with event-free survival (EFS) and overall survival (OS) were determined by univariate and multivariate analyses using backward stepwise Cox regression models. EFS and OS were plotted using Kaplan‒Meier curves. Results: This study included 19 patients with a median age of 33 years (range, 19‒65). Eleven (58%) and two (10.5%) patients had advanced-stage and central nervous system disease, respectively. Among 106 administered cycles, the median interval between cycles was 23 days (range, 19‒84 days). Sixteen patients (84%) achieved a complete response. After a median follow-up of 40.8 months, the 3-year EFS and OS rates were 78.95%. Patients with a low-risk International Prognostic Index (IPI) had better survival than those with intermediate-or high-risk IPI. Grade III‒IV hematological toxicities occurred in 88% of patients, while 73% had grade III‒IV mucositis. Conclusion In adult Burkitt lymphoma, the CALGB 1002 protocol provides high cure rates and can be administered promptly, but is associated with significant toxicity. Risk-adapted approaches and other, less toxic, chemotherapeutic regimens should be considered.

BACKGROUND: Streptococcus pneumoniae causes life-threatening infections such as meningitis, pneumonia, and febrile bacteremia, particularly in young children. The increasing number of drug-resistant isolates has highlighted the necessity for intervening and controlling disease. To achieve this, information is needed on serotype distribution and patterns of antibiotic resistance in children. METHODS: All cases of invasive pneumococcal disease (IPD) in children aged less than 15 yr recorded at King Khalid University Hospital, King Saud University, Riyadh, Saudi Arabia, were reviewed for serotyping and antibiotic susceptibility. Isolates were collected from 78 consecutive patients with IPD between 2009 and 2012. All collected isolates were subjected to serotyping by co-agglutination, sequential multiplex PCR, and single PCR sequetyping as previously described. RESULTS: The most frequently isolated IPD serotypes were 23F, 6B, 19F, 18C, 4, 14, and 19A, which are listed in decreasing order and cover 77% of total isolates. The serotype coverage for the pneumococcal conjugate vaccine (PCV)7, PCV10, and PCV13 was 77%, 81%, and 90%, respectively. Results from sequential multiplex PCR agreed with co-agglutination results. All serotypes could not be correctly identified using single PCR sequetyping. Minimum inhibitory concentration showed that 50 (64%) isolates were susceptible to penicillin, whereas 70 (90%) isolates were susceptible to cefotaxime. CONCLUSIONS: The most common pneumococcal serotypes occur with frequencies similar to those found in countries where the PCV has been introduced. The most common serotypes in this study are included in the PCVs. Addition of 23A and 15 to the vaccine would improve the PCV performance in IPD prevention.

This systematic review and meta-analysis aimed to examine the effect of the antioxidant alpha-lipoic acid (ALA) on various cardiometabolic risk factors and hormonal parameters in patients with polycystic ovary syndrome (PCOS). We searched PubMed, EMBASE, SCOPUS, Cochrane Library, and Web of Science databases without language restrictions until May 2023 to find randomized controlled trials (RCTs) that assessed the impact of ALA supplementation on anthropometric, glycemic, lipid, oxidative stress, and hormonal parameters in women with PCOS. Outcomes were summarized using the standardized mean difference (SMD) and 95% confidence interval (CI) in a random-effects model. An I2 statistic of >60% established significant between-study heterogeneity. The overall certainty of the evidence for each outcome was determined using the grading of recommendations, assessment, development, and evaluations system. Seven RCTs met the inclusion criteria. The ALA group had significant reductions in fasting blood sugar (fasting blood sugar (FBS), n=7 RCTs, SMD, -0.60; 95% CI, -1.10 to -0.10; I2=63.54%, moderate certainty of evidence) and homeostatic model assessment for insulin resistance (homeostatic model assessment of insulin resistance (HOMA-IR), n=4 RCTs, SMD, -2.03; 95% CI, -3.85 to -0.20; I2=96.32%, low certainty of evidence) compared with the control group. However, significant differences were observed between the groups in body mass index, insulin, estrogen, follicle-stimulating hormone, luteinizing hormone, testosterone, low-density lipoprotein, highdensity lipoprotein, triglyceride, total cholesterol, malondialdehyde, or total antioxidant capacity profiles. ALA supplementation improves FBS and HOMA-IR levels in women with PCOS. ALA consumption is an effective complementary therapy for the management of women with PCOS.

Background: and Purpose Various imaging paradigms are used for endovascular treatment (EVT) decision-making and outcome estimation in acute ischemic stroke (AIS). We aim to compare how these imaging paradigms perform for EVT patient selection and outcome estimation. Methods: Prospective multi-center cohort study of patients with AIS symptoms with multi-phase computed tomography angiography (mCTA) and computed tomography perfusion (CTP) baseline imaging. mCTA-based EVT-eligibility was defined as presence of large vessel occlusion (LVO) and moderate-to-good collaterals on mCTA. CTP-based eligibility was defined as presence of LVO, ischemic core (defined on relative cerebral blood flow, absolute cerebral blood flow, and cerebral blood volume maps) <70 mL, mismatch-ratio >1.8, absolute mismatch >15 mL. EVT-eligibility and adjusted rates of good outcome (modified Rankin Scale 0–2) based on these imaging paradigms were compared. Results: Of 289/464 patients with LVO, 263 (91%) were EVT-eligible by mCTA-criteria versus 63 (22%), 19 (7%) and 103 (36%) by rCBF, aCBF, and CBV-CTP-criteria. CTP and mCTA-criteria were discordant in 40% to 53%. Estimated outcomes were best in patients who met both mCTA and CTP eligibility-criteria and were treated with EVT (62% to 87% good outcome). Patients eligible for EVT by mCTA-criteria and not by CTP-criteria receiving EVT achieved good outcome rates of 53% to 57%. Few patients met CTP-criteria and not mCTA-criteria for EVT. Conclusions Simpler imaging selection criteria that rely on little else than detection of the occluded blood vessel may be more sensitive and less specific, thus resulting in more patients being offered EVT and arguably benefiting from it.
