Treatment Patterns and Clinical Outcomes in Patients with Hodgkin Lymphoma from Saudi Arabia, Türkiye, and South Africa: Subgroup Analysis from the International, Multi-center, Retrospective BHOLISTIC Study.

Objective: B-HOLISTIC was a real-world, retrospective study of treatment patterns and clinical outcomes in Hodgkin lymphoma (HL) in regions outside Europe and North America. This subgroup analysis reports findings from Saudi Arabia, Türkiye, and South Africa. Materials and methods: Patients aged ≥18 years and diagnosed with stage IIB-IV classical HL receiving frontline chemotherapy (frontline cHL) and/or relapsed/refractory HL (RRHL) from January 2010-December 2013 were assessed. The primary endpoint was progression-free survival (PFS) in patients with RRHL. Results: Overall, 694 patients (RRHL: n=178; frontline cHL: n=653) were enrolled. Among patients with RRHL, >80% received first salvage chemotherapy. The most common first salvage regimens were etoposide, methylprednisolone, cytarabine, cisplatin (ESHAP) in Saudi Arabia (78.3%) and dexamethasone, cytarabine, cisplatin (DHAP) in Türkiye (36.1%) and South Africa (40%). Median PFS (95% confidence interval [CI]) in the RRHL group was 5.1 (3.0-15.9), 19.7 (7.5-not reached), and 5.2 (1.1- 10.1) months in Saudi Arabia, Türkiye, and South Africa, respectively. The 5-year PFS and overall survival (95% CI) rates in patients with RRHL were 33.2% (21.6-45.2) and 78.2% (65.9-86.5) in Saudi Arabia, 42.5% (29.5-54.9) and 79.4% (67.2-87.5) in Türkiye, and 13.1% (4.2-27.0) and 53% (35.5-67.8) in South Africa, respectively. Conclusions: This study showed that the clinical outcomes in Türkiye and Saudi Arabia were generally comparable with Western countries during the study period, although Saudi Arabia had lower PFS rates. Conversely, the clinical outcomes in South Africa were suboptimal, emphasizing the need for novel therapies and improved progression to stem cell transplantation. Additionally, these data may serve as a control group for future studies in these countries and inform clinical decision-making.

Outcomes of Autologous stem cell transplantation in patients with primary refractory Diffuse Large B-cell lymphoma who demonstrate chemosensitivity to salvage chemotherapy.

Rituximab with anthracycline-based combination frontline chemoimmunotherapy can cure 50-60% of patients with diffuse large B-cell lymphoma (DLBCL). However, studies on the outcomes of patients with DLBCL who experience partial response (PR), stable or progressive disease in response to frontline rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (RCHOP) therapy are limited, as are data on the outcomes of high-dose chemotherapy (HDC) and autologous stem cell transplantation (ASCT) in patients with primary refractory DLBCL who demonstrate chemosensitivity to salvage chemotherapy (SC). We assessed the latter among 184 patients, 144 of whom started SC, with 84 responding and 72 receiving HDC-ASCT. The 5-year survival rate was 58.9%; the median overall survival (OS) was not reached. The difference in response to SC (partial response versus complete response) was significant, with higher 2- and 5-year OS rates in patients with CR (78.1% and 74.9%, respectively) than in those with PR (55.3% and 47%, respectively). The median OS for the whole group was 15 months and particularly patients who had progressive disease after frontline R-CHOP had dismal outcomes. Our study suggests that in patients with primary refractory DLBCL without initial progressive disease after frontline R-CHOP, the depth of response to SC before HDC-ASCT is predictive of relapse.

Impact of educational intervention on hypertension management by primary care physician: A randomized control trial.

Objective: The current study aimed to observe hypertension educational intervention's effect on general physicians (GPs) to improve blood pressure control and patient outcomes indirectly. Methods: This randomized control trial includes 42 GPs divided into 2 groups. GPs in group 1 receive face-to-face education with structured educational material on hypertension management strategies by a senior cardiologist. GPs in group 2 receive the print version of education material. The data was collected from six major cities in Pakistan. GPs with at least three years of experience in the broad primary care disciplines, with ages above 18 years, were included in the study. Results: A total of 42 physicians (21 from each group) completed questionnaires, while out of 420 hypertension patients, 105 newly diagnosed and already diagnosed patients enrolled under physicians of both groups. The educational material did just as well at informing clinicians as the face-to-face group intervention did and both the interventions had a significant effect on knowledge and BP control. Conclusion: After the 3-month follow-up, both interventions, including face-to-face and educational approaches, demonstrated significant effectiveness in improving knowledge and blood pressure control. Innovation: The study shows that hypertension educational intervention's effect on general physicians indirectly improves blood pressure control and patient outcomes. And emphasize for developing a hypertension educational program targeted at general physicians.

Mutations in the bone morphogenetic protein 15 gene causing defective protein secretion in Cholistani infertile sheep

Abstract Naturally occurring mutations in morphogenetic protein 15 (BMP15) are associated with decreased ovulation rate (OR), litter size (LS), and sterility. It is of a great interest to elucidate BMP15 gene in Cholistani sheep breed to uplift socio-economic status and the knowledge of Cholistani sheep breeding in Southern Punjab, Pakistan. In our study, a total of 50 infertile Cholistani sheep aged between 2-6 years and having no blood relation were screened for BMP15 mutations. For this purpose, a high-quality DNA was extracted from the blood of sheep followed by primer designing, Polymerase Chain Reaction (PCR) amplification, DNA sequencing, and in silico analyses. Out of total 50 samples, 9 samples including case 1 (T3), case 2 (T8), case 3 (T17), case 4 (T22), case 5 (T25), case 6 (T33), case 7 (T40), case 8 (T44), and case 9 (T47) were found positive for a variety of already reported and novel BMP15 mutations. Further in silico analyses of the observed mutations have shown the functional impact of these mutations on different characteristics (molecular weight, theoretical PI, estimated half-life, instability index, sub-cellular localization, and 3D confirmation) of the encoded proteins, possibly altering the normal functionality. In a nutshell, findings of this study have confirmed the possible essential role of the BMP15 mutations in the infertility of the Cholistani sheep.

Organoleptic characteristics and compositional profile of meat of growing Japanese quail fed different levels of poultry byproducts compost.

The poultry industry generates a lot of waste, including dead birds, manure, and poultry litter. Poultry waste should never be disposed of improperly because it can seriously harm the environment. The waste can be recycled as a feedstock for use in poultry feed by composting the litter and deceased birds. The compositional profile and organoleptic properties of the meat of growing Japanese quail were examined over the course of a 4-week trial to ascertain the effect of adding compost to the diet. In a completely randomized design (CRD), 1200 newly hatched quail chicks (Coturnix coturnix japonica) were divided into five treatment groups (diets with 0, 2.5, 5, 7.5, and 10% compost), each consisting of 40 birds with six replicates. The addition of compost to the diet had no noticeable effects on the organoleptic qualities of appearance, color, aroma, taste, texture, juiciness, tenderness, and acceptability (P>0.05). The compositional profile characteristics for chicks given compost at any level compared to chicks fed the control diet showed no differences (P>0.05). These findings suggest that the sensory characteristics and compositional profile of growing meat quails can be maintained when fed diets including up to 10% compost.

Assessing effect of feeding poultry byproducts compost on organoleptic characteristics and compositional profile of meat of broiler chickens.

Large amounts of waste, including dead birds, manure, and poultry litter, are produced by the poultry industry. Poultry waste should be disposed of properly to avoid major pollution and health risks. Composting litter and dead birds could be an option to recycle the waste and use in poultry feed. A study was conducted to investigate the effects of feeding composted poultry waste on the organoleptic qualities and compositional profile of the meat of broiler chickens. A total of 300 day-old broiler chicks (500-Cobb) were randomly allocated to five treatment groups replicated six times with 10 birds each, under a completely randomized design (CRD). Five iso-caloric and iso-nitrogenous diets including composted poultry byproducts at concentrations of 0, 2.5, 5, 7.5, and 10% were fed ad libitum to the birds from day 0 to day 35. The sensory grading and meat composition profile of 500 Cobb broiler chickens were tested at 35 days of age. The findings showed that there were no variations in the sensory profiles of the meat from birds given various diets (P>0.05). Although the results were somewhat lower for the chicks fed compost-containing diets than for the control group, this difference was deemed to be insignificant (P>0.05). Similarly, there were no variations in the compositional profile values of the meat between meat from birds fed various diets (P>0.05). These findings imply that broiler chickens may be raised on diets containing up to 10% poultry byproduct compost without any negative impacts on the meat's sensory quality or composition. Additionally, using compost into broiler diets may help to lower the cost of feed.

The lipid-lowering efficacy of rosuvastatin is associated with variations in SLCO1B1: a 12-month prospective cohort study.

OBJECTIVE: Statins' efficacy and safety are subject to wide inter-individual variability, partly due to genetic predisposition. Studies have shown that the genetic variations in the common solute carrier organic anion transporter family member 1B1 (SLCO1B1) gene polymorphisms affect the transport of statins' transport into hepatocytes, their plasma concentration, and circulation time. The ultimate result is variable and personalized statins response and statin-associated muscular symptoms (SAMS). Here we report an update on the differential response to rosuvastatin therapy in the Pakistani population. PATIENTS AND METHODS: A total of 166 hyperlipidemic patients on rosuvastatin were prospectively followed for 24 weeks. Muscle symptoms were recorded after 6-8 weeks of therapy, and assessment was done according to the SAMS-clinical index tool. Patients were genotyped for SLCO1B1 c.521T>C and c.388A>G polymorphisms, for association with lipid-lowering response and statin-associated muscle symptoms. The plasma level of rosuvastatin was determined through Liquid chromatography-mass spectrometry (LCMS) for possible correlation with adverse effects and lipid-lowering efficacy. RESULTS: Mean reduction in low-density lipoprotein cholesterol (LDL-C) was 42.34 mg/dl (p<0.001), 35.66 mg/dl (p<0.001), and 24.47 mg/dl (p=0.202) in reference, heterozygous and mutant homozygous groups of SLCO1B1 c.521T>C, respectively. A 15.70% and 42.14% diminished LDL-C reduction was observed in c.521TC and c.521CC, respectively, compared to the reference c.521TT genotype. Similarly, for SLCO1B1 c.388A>G, 20.50% and 29.40% less LDL-C lowering effect was observed in heterozygous and mutant homozygous carriers, respectively. SAMS were observed in 37% and 33% of heterozygous and minor homozygous, respectively, (p=0.059). The rosuvastatin plasma level was 1.89-fold higher in the c.521CC genotype than in the reference homozygous type. CONCLUSIONS: Differential lipid-lowering response and muscular symptoms due to rosuvastatin are associated with the SLCO1B1 common polymorphisms. Further studies are needed to validate dose adjustment and rationalization.

Impact of Risk Factors and Long Term Survival Analysis of Patients With Primary Refractory Hodgkin Lymphoma Who Underwent High Dose Chemotherapy and Autologous Stem Cell Transplant.

Patients with primary refractory Hodgkin lymphoma (ref-HL) can still be salvaged with high-dose chemotherapy (HDC) and autologous stem cell transplantation (auto-SCT). Outcomes of patients with ref-HL is poorer than those with relapsed HL, but most studies have included patients with both relapsed and refractory diseases, and separate analyses or studies on patients with ref-HL are limited. This study aimed to evaluate the outcomes of HDC auto-SCT and impact of various prognostic factors in patients with ref-HL at the time of primary treatment failure and subsequent survival at the time of failure post-HDC auto-SCT. This retrospective single-institution cohort analysis using an HDC and auto-SCT database was approved by the Institutional Research Advisory Counsel and Ethics Committee for identifying patients. We used the Fine and Gray competing risk analysis method, a regression model for outcome analysis, and the Kaplan-Meier (KM) method for survival analysis. The study cohort comprised 200 consecutive ref-HL patients who underwent HDC auto-SCT between 1996 and 2019. The median patient age was 22.75 years, and median follow-up was 106 months. Post-auto-SCT disease status was complete remission (CR) in 122 patients (61%), partial remission in 22 (11%), and progressive disease in 47 (23.5%). KM median progression-free survival (PFS) after auto-SCT was 43.9 months (5 years, 49.3%; 10 years, 45.5%). Median overall survival (OS) was 168.6 months (5 years, 61.2%: 10 years, 56.2%). Eighty-five patients (44.5%) died, 69 (34.5%) due to disease. Multivariate analysis identified similar adverse factors for both PFS and OS. For PFS, these adverse factors included stage III-IV at relapse (hazard ratio [HR], 1.65; P = .045), mediastinal involvement (HR, 2.01; P = .009), and absence of CR after salvage chemotherapy (HR, 2.2; P = .001). PFS with 0 or 1 adverse factors (not reached), 2 adverse factors (40.8 months), and 3 adverse factors (5.4 months) was significant (P < .001). For OS, significant adverse factors included stage III-IV at relapse (HR, 1.68; P = .045), mediastinal involvement (HR, 2.52; P = .007), and no CR after salvage chemotherapy (HR, 2.15; P = .004) were significant. OS with 0 or 1 adverse factors (not reached), 2 adverse factors (148.5 months), and 3 adverse factors (34.4 months) was significant (P < .001). The median OS after auto-SCT failure was 23.6 months; patients received post auto-SCT brentuximab/second SCT (not reached), other treatments (22.5 months), and supportive care (8.4 months) (P < .001). OS with 5 risk factors present at HDC auto-SCT failure- stage III-IV, failure at <12 months, tumor >5 cm, B symptoms, and low serum albumin-was 152 months for 0 or 1 risk factors, 30.9 months with 2 risk factors, and 9.45 months with 3 to 5 risk factors (P < .001). Ref-HL patients have encouraging survival after HDC auto-SCT and can even be salvaged after auto-SCT failure. Based on prognostic factors, survival prediction is possible. Patients who fail to respond to HDC auto-SCT may benefit from newer treatments strategies and may qualify for enrollment in clinical trials.

Perceptions and Early Outcomes of the Acuity Circles Allocation Policy Among Liver Transplant Centers in the United States.

Recently, a new liver allocation policy called the acuity circles (AC) framework was implemented to decrease geographic disparities in transplant metrics across donor service areas. Early analyses have examined the changes in outcomes because of the AC policy. However, perceptions among transplant surgeons and staff regarding the new policy remain unknown. Methods: A 28-item survey was sent to division chiefs and surgical directors of liver transplantation across the United States. Questions assessed the respondents' perceptions regarding center-level metrics and staff satisfaction. We used Organ Procurement and Transplantation Network data to study differences in allocation between the pre-AC implementation period (2019) and the post-AC implementation period (2020-2021). Results: A total of 40 participants completed this ongoing survey study. Most responses were from region 8 (13%), region 10 (15%), and region 11 (13%). Sixty-three percent of respondents stated that the wait time for a suitable offer for recipients with model of end-stage liver disease score <30 has decreased, whereas 50% stated that wait time for a suitable offer for recipients with model of end-stage liver disease score >30 has increased. However, most respondents (75%) felt that the average cost per transplant had increased and that the rate of surgical complications and 1-y graft survival had remained the same. In most states, an observable decrease in in-state liver transplantations occurred each year between 2019 and 2021. In addition, most allocation regions reported an increase in donations after circulatory deaths between 2019 and 2021. Conclusions: Perceptions of the new AC policy among liver transplant surgeons in the United States remain mixed, highlighting the potential strengths and concerns regarding its future impact. Further studies should assess the effects of the AC policy on clinical outcomes and liver transplantation access.

Effects of selenium supplementation on the growth performance, slaughter characteristics, and blood biochemistry of naked neck chicken.

This study examined how selenium-supplemented diets affected the performance of naked neck chickens. The birds were fed both organic and inorganic selenium at 0.30 ppm, while the control diet did not include any additional selenium. A total of 225 one-day-old naked neck chicks were randomly divided into 3 experimental groups, each of which was replicated 5 times (replicates) and contained 15 birds. This was done using a completely randomized design. The data was collected after growth, meat quality, and blood profile parameters were assessed. The findings showed that the birds fed inorganic selenium in the diet displayed increased (P < 0.05) feed intake followed by those administered organic selenium and the control diet. On the other hand, birds fed organic selenium in the diet showed enhanced body weight gain and better feed conversion ratio (P < 0.05). Similarly, organic selenium supplementation increased (P < 0.05) breast and thigh weight compared to inorganic selenium, but no other metrics, such as dressing percentage, drumstick weight, liver weight, gizzard weight, heart weight, or wing weight, significantly differed between treatments (P > 0.05). When compared to birds fed inorganic Se and control diet, the birds fed organic Se had greater (P < 0.05) blood levels of total protein and globulin. Additionally, it was discovered that organic Se-fed birds had greater (P < 0.05) blood Se concentrations than control and inorganic Se-fed birds. However, no differences between treatments were found in albumin, glucose, cholesterol, triglycerides, or uric acid (P > 0.05). In conclusion, adding Se-enriched yeast, as an organic selenium source, to diets may enhance the poor growth and slaughter characteristics of naked neck chicks without negatively affecting blood chemistry.

Molecular detection and prevalence of Rotavirus with acute gastroenteritis among the children of rural and urban areas / Detecção molecular e prevalência de rotavírus com gastroenterite aguda entre as crianças de áreas rurais e urbanas

Rotavirus is the main infective agent of acute gastroenteritis (AGE) in children under the age of five years and causing significant morbidity as well as mortality throughout the world. The study was carried out to detect the prevalence rate, genotypes strain and risk factors of Rotavirus among the children of rural and urban areas of district Bannu Khyber Pakhtunkhwa Pakistan. A total of 180 stool samples were collected from children under the age of 5 years from two major hospitals of Bannu from January to December (2015). The samples were analyzed by Reverse-transcriptase Polymerase Chain Reaction (RT-PCR) for the detection of Rotavirus, positive samples were further processed for genotyping (G and P type) through specific PCR. Of the total, 41 (23%) samples were positive for Rotavirus. The most prevalent G genotypes found were: G3, G8, G9 (each 29%), followed by G10 (15%), and G11 (10%). Whereas the prevalent P genotypes were: P-8 (25%), P-4 and P-10 (each 20%), P-9 (15%), followed by P-6 and P-11 (each 10%). Moreover, Rotavirus infection was more prevalent in summer (23.73%) and winter (22.7%) than spring (20%) and autumn (21.4%). Rotavirus infection exhibited high frequency in June (14%), October (8%) and November (6%). It is concluded that Rotavirus is more prevalent in children and various genotypes (G and P) of Rotavirus are present in the study area. Lack of studies, awareness and rarer testing of Rotavirus are the principal reasons of virus prevalence in district Bannu, Pakistan.

Assessing growth performance, morphometric traits, meat chemical composition and cholesterol content in four phenotypes of naked neck chicken.

The present study was conducted to assess the growth performance, morphometric traits, muscle chemical composition and cholesterol content in four phenotypes of naked neck chicken (black, white-black, light brown and dark brown). A total of 320-day-old chicks, 80 from each phenotype, were randomly stratified into 20 replicates (16/replicate), according to a completely randomized design. The results showed higher final body weight, weight gain, and better FCR in both light brown and dark brown phenotypes whereas time of gains was found to be greater in dark brown phenotype. Keel length and shank circumference were greater in dark brown whereas wing spread was found to be higher in light brown phenotype. Drumstick circumference and body length did not show any significant differences (P > 0.05) across the phenotypes. Dry matter was found to be higher in white black, crude protein in black, white black and dark brown, moisture in light brown, and cholesterol content in black whereas ether extract and ash content were found to be greater in black and white black phenotypes. In conclusion, both light brown and dark brown phenotypes showed superior growth performance and morphometric traits. Similarly, from a health point of view, the dark brown and light brown phenotypes seem superior because their cholesterol content was low. Thus, it is strongly recommended that there should be a conscious effort to improve economically important traits of the light and dark brown birds to be used as dual-purpose slow growing chicken, especially in developing countries.

Mutations in the bone morphogenetic protein 15 gene causing defective protein secretion in Cholistani infertile sheep.

Naturally occurring mutations in morphogenetic protein 15 (BMP15) are associated with decreased ovulation rate (OR), litter size (LS), and sterility. It is of a great interest to elucidate BMP15 gene in Cholistani sheep breed to uplift socio-economic status and the knowledge of Cholistani sheep breeding in Southern Punjab, Pakistan. In our study, a total of 50 infertile Cholistani sheep aged between 2-6 years and having no blood relation were screened for BMP15 mutations. For this purpose, a high-quality DNA was extracted from the blood of sheep followed by primer designing, Polymerase Chain Reaction (PCR) amplification, DNA sequencing, and in silico analyses. Out of total 50 samples, 9 samples including case 1 (T3), case 2 (T8), case 3 (T17), case 4 (T22), case 5 (T25), case 6 (T33), case 7 (T40), case 8 (T44), and case 9 (T47) were found positive for a variety of already reported and novel BMP15 mutations. Further in silico analyses of the observed mutations have shown the functional impact of these mutations on different characteristics (molecular weight, theoretical PI, estimated half-life, instability index, sub-cellular localization, and 3D confirmation) of the encoded proteins, possibly altering the normal functionality. In a nutshell, findings of this study have confirmed the possible essential role of the BMP15 mutations in the infertility of the Cholistani sheep.

Biodegradation of petroleum by bacteria isolated from fishes of Indian Ocean / Biodegradação do petróleo por bactérias isoladas de peixes do oceano Índico

In this study, oil degrading bacteria discovered from fish living near the oil ports at Karachi in Pakistan were characterized. The bacteria isolated from skin, gills, and gut in fish could consume crude oil as a source of carbon and energy. Total 36 isolates were tested using Nutrient Agar (NA) and MSA media with different crude oil concentrations (0.2%, 0.5%, 0.7%, 1%, 2%, and 5%) and 4 out of 36 isolates (two Gram positive and two Gram negative bacteria) were selected for further identification. 16S rRNA gene sequencing revealed that the isolates are related to Bacillus velezensis, Bacillus flexus, Pseudomonas brenneri and Pseudomonas azotoforman. Oil degrading potential of these bacteria was characterized by GC-MS analysis of degradation of oil components in crude oil as well as engine oil. We found that one (2, 6, 10, 14-Tetramethylpentadecane) out of 42 components in the crude oil was fully eliminated and the other oil components were reduced. In addition, 26 out of 42 oil components in the engine oil, were fully eliminated and the rest were amended. Taken together, these studies identify that B. velezensis, B. flexus, P. brenneri and P. azotoforman have high oil degrading potential, which may be useful for degradation of oil pollutants and other commercial applications.

Neste estudo, bactérias degradadoras de óleo descobertas em peixes que vivem perto dos portos de petróleo em Karachi, no Paquistão, foram caracterizadas. As bactérias isoladas da pele, guelras e intestinos dos peixes podem consumir petróleo bruto como fonte de carbono e energia. No total, 36 isolados foram testados usando Agar Nutriente (NA) e meio MSA com diferentes concentrações de óleo bruto (0,2%, 0,5%, 0,7%, 1%, 2% e 5%) e 4 de 36 isolados (dois Gram positivos e duas bactérias Gram negativas) foram selecionadas para posterior identificação. O sequenciamento do gene 16S rRNA revelou que os isolados estão relacionados a Bacillus velezensis, Bacillus flexus, Pseudomonas brenneri e Pseudomonas azotoforman. O potencial de degradação do óleo dessas bactérias foi caracterizado pela análise de GC-MS da degradação dos componentes do óleo no óleo cru, bem como no óleo do motor. Descobrimos que um (2, 6, 10, 14-tetrametilpentadecano) de 42 componentes do óleo cru foi totalmente eliminado e os outros componentes do óleo foram reduzidos. Além disso, 26 dos 42 componentes do óleo do motor foram totalmente eliminados e o restante corrigido. Juntos, esses estudos identificam que B. velezensis, B. flexus, P. brenneri e P. azotoforman têm alto potencial de degradação de óleo, o que pode ser útil para a degradação de poluentes de óleo e outras aplicações comerciais.

Molecular detection and prevalence of Rotavirus with acute gastroenteritis among the children of rural and urban areas.

Rotavirus is the main infective agent of acute gastroenteritis (AGE) in children under the age of five years and causing significant morbidity as well as mortality throughout the world. The study was carried out to detect the prevalence rate, genotypes strain and risk factors of Rotavirus among the children of rural and urban areas of district Bannu Khyber Pakhtunkhwa Pakistan. A total of 180 stool samples were collected from children under the age of 5 years from two major hospitals of Bannu from January to December (2015). The samples were analyzed by Reverse-transcriptase Polymerase Chain Reaction (RT-PCR) for the detection of Rotavirus, positive samples were further processed for genotyping (G and P type) through specific PCR. Of the total, 41 (23%) samples were positive for Rotavirus. The most prevalent G genotypes found were: G3, G8, G9 (each 29%), followed by G10 (15%), and G11 (10%). Whereas the prevalent P genotypes were: P-8 (25%), P-4 and P-10 (each 20%), P-9 (15%), followed by P-6 and P-11 (each 10%). Moreover, Rotavirus infection was more prevalent in summer (23.73%) and winter (22.7%) than spring (20%) and autumn (21.4%). Rotavirus infection exhibited high frequency in June (14%), October (8%) and November (6%). It is concluded that Rotavirus is more prevalent in children and various genotypes (G and P) of Rotavirus are present in the study area. Lack of studies, awareness and rarer testing of Rotavirus are the principal reasons of virus prevalence in district Bannu, Pakistan.
