Abstract
BACKGROUND & AIMS Hepatitis delta virus (HDV) is a satellite RNA virus that requires the hepatitis B virus (HBV) for assembly and propagation. Individuals infected with HDV progress to advanced liver disease faster than HBV-monoinfected individuals. Recent studies have estimated the global prevalence of anti-HDV antibodies among the HBV-infected population to be 5-15%. This study aimed to better understand HDV prevalence at the population level in 25 countries/territories. METHODS We conducted a literature review to determine the prevalence of anti-HDV and HDV RNA in hepatitis B surface antigen (HBsAg)-positive individuals in 25 countries/territories. Virtual meetings were held with experts from each setting to discuss the findings and collect unpublished data. Data were weighted for patient segments and regional heterogeneity to estimate the prevalence in the HBV-infected population. The findings were then combined with The Polaris Observatory HBV data to estimate the anti-HDV and HDV RNA prevalence in each country/territory at the population level. RESULTS After adjusting for geographical distribution, disease stage and special populations, the anti-HDV prevalence among the HBsAg+ population changed from the literature estimate in 19 countries. The highest anti-HDV prevalence was 60.1% in Mongolia. Once adjusted for the size of the HBsAg+ population and HDV RNA positivity rate, China had the highest absolute number of HDV RNA+ cases. CONCLUSIONS We found substantially lower HDV prevalence than previously reported, as prior meta-analyses primarily focused on studies conducted in groups/regions that have a higher probability of HBV infection: tertiary care centers, specific risk groups or geographical regions. There is large uncertainty in HDV prevalence estimates. The implementation of reflex testing would improve estimates, while also allowing earlier linkage to care for HDV RNA+ individuals. The logistical and economic burden of reflex testing on the health system would be limited, as only HBsAg+ cases would be screened. IMPACT AND IMPLICATIONS There is a great deal of uncertainty surrounding the prevalence of hepatitis delta virus among people living with hepatitis B virus at the population level. In this study, we aimed to better understand the burden in 25 countries and territories, to refine techniques that can be used in future analyses. We found a lower prevalence in the majority of places studied than had been previously reported. These data can help inform policy makers on the need to screen people living with hepatitis B virus to find those coinfected with hepatitis delta virus and at high risk of progression, while also highlighting the pitfalls that other researchers have often fallen into.

Abstract
Delayed passage of meconium or constipation during the perinatal period is traditionally regarded as a signal to initiate further work up to evaluate for serious diagnoses such as Hirschsprung's disease (HD), meconium ileus due to Cystic Fibrosis, etc. The diagnosis of HD particularly warrants invasive testing to confirm the diagnosis, such as anorectal manometry or rectal suction biopsy. What if there was another etiology of perinatal constipation, that is far lesser known? Cow's milk protein allergy (CMPA) is often diagnosed in infants within the first few weeks of life, however, there are studies that show that the CMPA allergen can be passed from mother to an infant in-utero, therefore allowing symptoms to show as early as day one of life. The presentation is more atypical, with perinatal constipation rather than with bloody stools, diarrhea, and vomiting. The diagnosis and management would be avoidance of cow's milk protein within the diet, with results and symptom improvement in patients immediately. Therefore, we discuss whether an alternative pathway to address perinatal constipation should be further discussed and implemented to potentially avoid invasive techniques in patients. This entails first ruling out CMPA with safe, noninvasive techniques with diet modification, and if unsuccessful, then moving forward with further diagnostic modalities.

Abstract
Abstract
Study question
does the use of IMSI technique in sperm selection during ICSI in case of male factor enhance blastocyst formation?
Summary answer
The use of IMSI technique enhanced the ferritization and blastulation rates as well the blastocyst quality in comparison with the conventional ICSI technique
What is known already
Prior to sperm injection the morphology of the sperm cell is evaluated with high magnification Diffraction Interference Contrast (DIC) microscopy. ICSI is performed using morphologically well-shaped spermatozoa selected within the limits of the conventional ICSI inverted microscope magnification of x400. However, it became evident that the morphology of the individual spermatozoon used for microinjection into the oocyte is associated to both fertilization and pregnancy outcome.The impact of nuclear vacuoles in the head of spermatozoa on pregnancy outcome was analyzed too, showing that microinjection of vacuolated sperm reduced the pregnancy rate and was associated with a higher risk for early abortion.
Study design, size, duration
A prospective cohort observational randomized sibling-oocyte study
A total of 300 infertile couples undergoing ICSI were included in the study from August 2020 to July 2021.
Ethical approval from Alexandria University, faculty of Medicine.
Participants/materials, setting, methods
A total of 300 infertile couples undergoing ICSI, Male factor infertility according to the World Health Organization (WHO) criteria 2010, patients with Azoospermia.and sperm concentration less than 0.1 million/mL were excluded.The oocytes of each patient were randomly divided into two groups in 1 to 1 ratio. One group was injected with sperms selected by normal magnification (3357) oocytes and the other group was injected with sperms selected by high magnification (IMSI) technique (3384) oocytes.
Main results and the role of chance
Statistical results according to number of cases showed that IMSI is significantly higher than ICSI in the number of fertilized oocytes (Mean± SD was 9.46±4.10vs. 9.02 ± 4.20, P ≤ 0.001), number of blastocysts (Mean± SD was 4.74±3.42 vs. 4.47±3.27, P = 0.035) and number of good quality blastocysts (Mean± SD was 1.97±2.57 vs. 1.75±2.50, P = 0.009), with No Significant difference in the number of injected oocytes.Comparison between ICSI and IMSI according to rates related to number of oocytes. Statistical results according to rates showed that IMSI is significantly higher than ICSI in fertilization rate (Mean± SD was 84.25 ± 16.57 vs. 80.01 ± 17.95, P ≤ 0.001), and the rate of good quality blastocysts (Mean± SD was 17.04 ± 18.47 vs. 15.59 ± 18.71, P = 0.04). No Significant difference in the blastulation rate P = 0.106. Comparison between ICSI and IMSI according to total number of injected oocytes (n = 6741) Statistical results according to total number of injected oocytes showed that IMSI is significantly higher than ICSI in fertilized oocytes (83.9% vs. 80.6% P = 0.001), and blastocysts with good quality (17.4% vs. 15.7%, P = 0.05). No Significant difference in the total number of blastocysts P = 0.075.
Limitations, reasons for caution
implantation, pregnancy and abortion rates were not included in the study
Wider implications of the findings
Similar to the present result and agreement to our suggestion several studies showed higher fertilization and blastocyst formation with the use of IMSI techniques and others showed higher implantation and pregnancy rates and lower miscarriage rates.Our recommendation is to use IMSI technique during sperm selection for treating infertile couples

Abstract
BACKGROUND AND PURPOSE Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2) infection is associated with hypercoagulability. We sought to evaluate the demographic and clinical characteristics of cerebral venous thrombosis among patients hospitalized for coronavirus disease 2019 (COVID-19) at 6 tertiary care centers in the New York City metropolitan area. MATERIALS AND METHODS We conducted a retrospective multicenter cohort study of 13,500 consecutive patients with COVID-19 who were hospitalized between March 1 and May 30, 2020. RESULTS Of 13,500 patients with COVID-19, twelve had imaging-proved cerebral venous thrombosis with an incidence of 8.8 per 10,000 during 3 months, which is considerably higher than the reported incidence of cerebral venous thrombosis in the general population of 5 per million annually. There was a male preponderance (8 men, 4 women) and an average age of 49 years (95% CI, 36-62 years; range, 17-95 years). Only 1 patient (8%) had a history of thromboembolic disease. Neurologic symptoms secondary to cerebral venous thrombosis occurred within 24 hours of the onset of the respiratory and constitutional symptoms in 58% of cases, and 75% had venous infarction, hemorrhage, or both on brain imaging. Management consisted of anticoagulation, endovascular thrombectomy, and surgical hematoma evacuation. The mortality rate was 25%. CONCLUSIONS Early evidence suggests a higher-than-expected frequency of cerebral venous thrombosis among patients hospitalized for COVID-19. Cerebral venous thrombosis should be included in the differential diagnosis of neurologic syndromes associated with SARS-CoV-2 infection.

Abstract
BACKGROUND There are no studies in Qatar or in the Middle East to investigate parental perception of healthy diet in childhood. PURPOSE To investigate parental perception of childhood healthy diet in the State of Qatar. METHODS Cross-sectional prospective study at Hamad Medical Corporation, State of Qatar. Parents of children <14 years old were invited to complete a questionnaire. RESULTS A total of 398 parents agreed to participate, while 22 parents refused (response rate 94%). About 80% of parents were between 20 and 39 years of age, and 77% were females. Around 230 (58%) parents had ≥1 housemaid to help with housework, including food preparation. Whilst 151 children (37%) fell into the overweight and obese category, only 68 parents (17%) perceived that their child was in this category. Less than half the participants (n = 179, 45%) stated that childhood weight should be monitored prior to 5 years of age, while around 35% stated the same, but for children ages 5-14 years. Most participants (n = 324, 81%) agreed that parental eating habits could influence childhood weight. In terms of food preparation at home, mothers cooked almost 50% of the times, housemaids 30%, followed by grandmothers (16.6%), and fathers (3.4%). When asked about the frequency of school meals being prepared at home, 237 parents (60%) prepared their children's lunch box only 1-2 times per week. Moreover, 63% of parents chose the quality of food based on nutritional values, while 44% and 35% chose it based on safety and taste, respectively. When queried about whether the child's pediatrician or the primary care physician counsel families regarding childhood healthy diet, 187 families (47%) had not received counseling by their children's health care providers. Most families agreed that healthy diets lead to better school performance (n = 372, 94%) and better physical activity quality (n = 379, 96%). Compared to families living in the rural areas, parents living in the capital Doha had better insights that healthy diets result in better in school performance (p = 0.032). CONCLUSION Parental perception is an important target for public health interventions. Within the current sample, families were aware of the positive impact of healthy diet on overall wellbeing. Qatar is a well-resourced country and it would be cost effective to train and professionally develop pediatricians and primary care physicians to be more proactive in tackling childhood obesity.

Abstract
Abstract
Introduction
Chronic kidney disease (CKD) is associated with increased morbidity and mortality. Cardiovascular disease (CVD) is the most common complication and a chief cause of death in patients with end stage renal disease (ESRD) accounting for 45% to 50% of causes of death in ESRD patient. Pulmonary hypertension (PH) occurs frequently in patients with CKD. The role of hemodialysis in reducing pulmonary artery pressure (PAP) and improving RV systolic function in not properly studied.
Purpose
To evaluate the effect of hemodialysis on Right ventricular (RV) systolic function and Pulmonary artery pressures using echocardiography in newly diagnosed end stage renal disease patients and after three months of regular hemodialysis.
Patients and Methods
30 patients recently diagnosed to have ESRD were enrolled and were followed up after three months. Trans-thoracic echocardiography was done prior to the first dialysis session and after three months of regular hemodialysis to asses RV systolic function and PAP.
Results
There was a significant improvement of RV systolic function assessed by trans-annular plane systolic excursion (TAPSE)(mm)(pre dialysis 18.9 ± 3.76, post 21.56 ±3.51, p <0.01), fractional area change (FAC)(%)(pre dialysis 41.27 ± 8.9, post 47.5 ± 6.1, p < 0.01),tricuspid lateral annular systolic velocity (S’)(cm/s) (pre dialysis 12.3 ± 2.79, post 14.16 ± 2.3, p < 0.01),myocardial performance index (MPI)(pre dialysis 0.2 ± 0.1, post 0.1 ± 0.1, p < 0.01)and right ventricular outflow tract fractional shortening (RVOT-FS)(%)(pre dialysis 36.5 ± 9.5, post 39.3 ± 8.6, p < 0.01)post dialysis (P value <0.01). All parameters of assessing pulmonary artery pressures; systolic pulmonary artery pressure (PASP)(mmHg)(pre dialysis 48.03 ± 17.16, post 35.12 ± 14.73, p < 0.01), pulmonary diastolic artery pressure (PADP)(mmHg)(pre dialysis 24.05 ± 9.7, post 18.12 ± 9.64, p < 0.01), mean pulmonary artery pressure (MPAP)(mmHg) (pre dialysis 35.61 ± 15.07, post 25.8 ± 12.06, p < 0.01), pulmonary capillary wedge pressure (PCWP)((pre dialysis 23.28 ± 8.74, post 17.39 ± 5.87, p < 0.01) and pulmonary vascular resistance (PVR)(Wood unit)(pre dialysis 1.89 ± 0.57, post 1.43 ± 0.46, p < 0.01) improved significantly post dialysis (P value <0.01).There was a significant inverse correlation between the duration of renal impairment and the improvement in SPAP and PCWP after the initiation of dialysis (P values are 0.021 and 0.015, Correlation co-efficient -0.421, -0.441 respectively). The best cut-off value for weight reductionduring dialysis for prediction of improvement of SPAP is 2.75 Kg (AUC = 0.950, CI = 0.881-1.000, P value < 0.01).
Conclusions
The present study shows that significant improvement occurred in all RV systolic function parameters and all parameters of assessing pulmonary artery pressures post dialysis in patients recently diagnosed to have ESRD. RVOT FS is a reliable method for assessing RV function and it is significantly correlated only with TAPSE and FAC at the baseline before dialysis.

Abstract
The course and severity of systemic lupus erythematosus (SLE) in children is generally similar to the adult form with potential serious organ system involvement, there are, however, factors that influence the prevalence and clinical behavior of the disease. Our objective was to analyse the organ system involvement and immunological findings in Kuwaiti children with SLE in relation to gender and age of onset and compare these findings to that in published reports. Organ system involvement and serologic profiles were analysed in 35 children with SLE. The major organ systems studied were: renal, hematological, cardiac, pulmonary, hepatic and the central nervous system. The prevalence of ANA, anti-dsDNA, anti-Sm, SSA, SSB and anti-cardiolipin antibodies were studied in addition to complement C3 and C4 levels. The results showed that a high percentage of children had hematological involvement (34%); thrombocytopenia (23%) and hemolytic anemia (20%). Renal involvement was proven by biopsy in only 10 children (29%). Neuropsychiatric manifestations were seen in five (14%) of patients. Males had a tendency for major organ involvement relative to females. All patients had positive ANA tests. All males had positive anti-dsDNA tests compared to 86% of female patients. The most significant finding in this study is the high frequency of hematological manifestations and the relatively low incidence of renal disease and neuropsychiatric abnormalities in Kuwaiti children with SLE.

Abstract
Environmental variables in a malaria geographic information system [GIS] database were analysed to discriminate between governorates at high and low risk of malaria. Only Fayoum governorate was categorized as a high risk area for malaria during the last 2 decades. Discriminant models correctly classified 96.3% of the risk categories and indicated that the most important predictor of risk is hydrogeology. Further GIS spatial analysis indicated that the high malaria risk in Fayoum is associated with a unique environmental envelope of biotic [presence of both efficient malaria vectors] and abiotic [hydrogeology and soil] variables. Recommendations for surveillance and control are discussed.

Abstract
The prevalence of human leukocyte antigen (HLA) DR alleles has been determined in 69 Kuwaiti Arab children with juvenile rheumatoid arthritis (JRA) and compared to that in 212 ethnically matched normal healthy controls using a PCR-sequence specific primers (PCR-SSP) method. A very high incidence of DR3 was detected in JRA patients compared to the controls (P < 0.0001, RR = 2.235). The high incidence of HLA-DR3 in JRA patients was accounted for mainly by an excess of DRB1*0307 (P < 0.05, RR = 3.072) and DRB1*0308 (P < 0.009, RR = 2.663) compared to the controls. Moreover, DR3 was more prevalent when patients with ANA-positive JRA were analysed separately; 73% compared to 58% for the whole JRA patient group. The frequency of DR1 was also higher in the JRA group compared to controls (P = 0.019, RR = 3.585). Although the incidence of some alleles was higher in the control group (DR13 and DR7), none reached a statistically significant level. All the patients with iridocyclitis had either a DR1 or DR3 allele, except for one child. The frequency of DRB1*03 was found to be much higher in the polyarticular subtype of Kuwaiti JRA cases compared to the oligoarticular subgroup and the controls. Also, a non-significant increase in the frequency of the DRB1*04, *11 and *15 alleles was detected in the polyarticular subtype of the Kuwaiti JRA cases compared to the controls.

Abstract
Pre-capillary pulmonary hypertension was the presenting sign of a CREST syndrome in a 65 year old woman. The diagnosis of this form of scleroderma is based on the association of a number of features (calcinosis, Raynaud's phenomenon, oesophageal dyskinesia, sclerodactylia and telangectasia). Scleroderma is the systemic disease which is usually complicated by pre-capillary pulmonary hypertension. This complication is observed in about 13% of CREST syndromes, but very rarely as severe pre-capillary pulmonary hypertension. The diagnosis of pre-capillary pulmonary hypertension carries a poor prognosis with a 2 year survival rate of about 40%. Treatment is usually with calcium inhibitors but with no effect on prognosis. The use of prostacycline and its analogue, iloprost, is an interesting therapeutic strategy, currently under evaluation. Cardiopulmonary transplantation is the only treatment of very severe forms, despite the progressive character of the condition. All cases of pre-capillary pulmonary hypertension require complete aetiological investigation to exclude a systemic disease, especially a scleroderma and, above all, a CREST syndrome.

Abstract
The Hemophilus influenzae blood culture and nasopharyngeal isolates, collected during a limited Surveillance of Antimicrobial Resistance in 1991-1993 from 1,635 Egyptian children under 5 years of age, presenting with pneumonia to Embaba and Abbassia Fever Hospitals, were serotyped. The 8 blood culture isolates confirmed H. influenzae to be responsible for 0.5% of the cases of pneumonia, versus 50 Streptococcus pneumoniae blood culture isolates from the same population that confirmed it responsible for 3.1% of the cases. The invasive Hemophilus strains were exclusively isolated from infants below 1 year, from one hospital (Embaba), on one winter season (January to March, 1992). On serotyping, 50% of the blood culture isolates were found to be non-b by latex agglutination. Some 297 nasopharyngeal isolates from cases of pneumonia were also serotyped and 45% were found to be non-b, thus confirming the invasive strains findings. Furthermore, the typing results from ARI-free controls nasopharyngeal isolates--though limited--were consistent with the findings and showed a 43% proportion of non-b. These findings put a question mark on the benefit of a large scale use of the available H. influenzae type b polysaccharide and conjugated vaccines in Egypt. But before interpreting out data in terms of vaccine needs, more specifically designed epidemiological studies need to be conducted to assess the role of H. influenzae as a pathogen in Egypt.

Abstract
The relationship among daily cigarette consumption, washed and non-washed RBC filterability time (FT) as an indicator of erythrocyte deformability and echocardiographic left ventricular mass (LVM) were examined in 25 clinically healthy smokers and in 25 non-smoking controls matched for sex and age. FT of non-washed RBC was significantly higher in smokers than in non-smokers (25.2 +/- 3.6 vs. 16.8 +/- 2.2 min, P < 0.001). A highly significant linear correlation between number of cigarette consumption and FT was found. These differences were not observed when RBC were washed three times with isotonic saline. LVM was significantly greater in smokers (85.5 +/- 13.4 g/m2) than in controls (61.8 +/- 6.7 g/m2, P < 0.001). A linear correlation between daily cigarette consumption and LVM was observed. A positive relationship between LVM and FT of non-washed RBC was also found. These results demonstrated that LVM is significantly elevated in smokers and is linearly correlated with both cigarette consumption and RBC filtratibility. The increased deformability found in smokers may be a determinant to the cardiac hypertrophy. The association of both elevated LVM and rheological impairment may indicate unfavourable prognosis.

Abstract
Air pollution is a national problem, that recognizes no geographical or political boundaries. Most of the atmospheric lead is emitted from two main sources, motor vehicles and industrial sources, such as metal melting, coal and oil combustion, iron and steel production. The aim of the present work is to measure the blood lead level among residents near and far from the high ways, to evaluate the effect of motor vehicle emission on the environmental pollution along the high ways in Riyadh City.

Abstract
Using nationally representative sample survey data collected in 1986, this study evaluates the training and service programs for menstrual regulation (MR), and estimates the number of MR procedures performed during 1986, in Bangladesh. The results show that most of the MR providers, who received either formal or informal training, were physicians and family welfare visitors (paramedics) employed by the government. They were trained in various aspects of MR performance, including contraindications and complications associated with MR, the techniques of MR performance and follow-up procedures, and maintenance and sterilization of MR equipment. Averages of 20.5 and 13.0 MR procedures were performed by formally and informally trained physicians, respectively, in the three-month period preceding the date of interview. The corresponding average numbers for formally and informally trained family welfare visitors were 11.6 and 9.1, respectively. A total of 241,442 MR cases were estimated to have been performed between August 1985 and July 1986.
