ABSTRACT
Purpose@#To determine the effect of zinc deficiency on fecal protein, electrolyte, and shortchain fatty acid levels in both heat-stable (ST) and heat-labile (LT) enterotoxigenic Escherichia coli (ETEC)-induced diarrhea in rats. @*Methods@#Albino rats, weighing 100 to 150 g, were divided into 2 groups, with 15 animals each: non-zinc and zinc-deficient. These two groups were sub-divided into three sub-groups with five rats each: control (saline); LT-ETEC; and ST-ETEC. Sodium phytate (30 mmol/L) was added to the animals’ water to induce zinc deficiency, while diarrhea was induced using 5×10 9 ETEC cells/mL. Fecal protein levels were estimated using the Bradford method, while sodium and potassium levels were determined using atomic absorption spectrophotometry. Shortchain fatty acids were measured using gas chromatography-mass spectrometry. @*Results@#Among the non-zinc and zinc-deficient groups, there were significant increases (p=0.04), (p=0.03) in fecal protein concentrations (mg/mL) in the LT-ETEC- (4.50±0.33), (6.50±0.26) and ST-ETEC- (3.85±0.19), (5.98±0.32) induced groups compared to the control groups (2.60±0.52), (3.50±0.11) respectively. Fecal sodium and potassium levels (mg/L) were significantly (v=0.029) increased in non-zinc-deficient rats induced with LT-ETEC (9.35±0.95, 1.05±0.48), and ST-ETEC (9.96±1.02, 1.21±0.45) compared with the control group (8.07±0.44, 0.47±0.17) but the increase were not statistically significant (p=0.059) in the zinc deficient rat groups. Fecal acetate and propionate levels (mg/g) significantly (p=0.032) increased when induced with LT-ETEC and ST-ETEC in non-zinc and zinc-deficient groups compared with the control groups. @*Conclusion@#Zinc deficiency among rats with ETEC-induced diarrhea elevated fecal protein loss but may not have an effect on fecal sodium, potassium and short-chain fatty acid levels.
ABSTRACT
The Indian Crested Porcupine (Hystrix indica) is classified as an agricultural pest species. It feeds on plants and crops; hence, it is responsible for massive financial losses worldwide. The current study was conducted to assess the diet composition of Indian Crested Porcupine in District Bagh, Azad Jammu and Kashmir (AJ&K). Thus, fecal samples were collected and examined from different sampling sites. Reference slides of the material collected from the study area were prepared for identification of dietary components in fecal pellets. A total of 80 fecal samples were collected and processed. Percent relative frequencies (P.R.F.) were calculated for each plant species recovered from pellets. Data revealed that Indian Crested Porcupine consumed 31 plant species in its diet, among them Zea mays (34.31±7.76) was the most frequently selected species followed by Rumex obtusifolius (15.32±2.57) and Melia azedarach (12.83±4.79). The study revealed that the greatest diversity of (n=20) plant species were consumed in summer season while minimum (n=13) species were used during winter. Among the parts of plants, stem was highly consumed in spring (57.2%) as compared to seed in fall (36.7%) while spikes and leaf were the least recovered parts from the fecal matter. The Berger-Parker diversity index showed highly diversified food (10.92) in the summer time of the year as compared to the autumn season (2.95). This study provides a baseline for the diet preference of this pest in the study area. Based on current findings, a detailed investigation on damage assessment, exploration, habitat use and management of Indian Crested Porcupine in AJ&K has been recommended.
O porco-espinho de crista indiano (Hystrix indica) é classificado como uma espécie de praga agrícola. Alimenta-se de plantas e colheitas; portanto, é responsável por enormes perdas financeiras em todo o mundo. O estudo atual foi realizado para avaliar a composição da dieta do porco-espinho de crista indiano nos distritos de Bagh, Azad Jammu e Caxemira (AJ&K). Assim, amostras fecais foram coletadas e examinadas em diferentes locais de amostragem. Lâminas de referência do material coletado na área de estudo foram preparadas para identificação dos componentes da dieta em pellets fecais. Um total de 80 amostras fecais foi coletado e processado. As frequências relativas percentuais (P.R.F.) foram calculadas para cada espécie de planta recuperada de pelotas. Os dados revelaram que o porco-espinho indiano consumiu 31 espécies de plantas em sua dieta, entre elas Zea mays (34,31 ± 7,76) foi a espécie mais selecionada, seguida por Rumex obtusifolius (15,32 ± 2,57) e Melia azedarach (12,83 ± 4,79). O estudo revelou que a maior diversidade de (n = 20) espécies de plantas foi consumida no verão, enquanto o mínimo (n = 13) espécies foi utilizado durante o inverno. Entre as partes das plantas, o caule foi muito consumido na primavera (57,2%) em relação à semente no outono (36,7%), enquanto a espiga e a folha foram as partes menos recuperadas da matéria fecal., O índice de diversidade de Berger-Parker mostrou alimentos altamente diversificados (10,92) no verão do ano em comparação com o outono (2,95). Este estudo fornece uma linha de base para a preferência alimentar dessa praga na área de estudo. Com base nas descobertas atuais, uma investigação detalhada sobre avaliação de danos, exploração, uso de habitat e gerenciamento de porco-espinho de crista indiano em AJ&K foi recomendada.

A research was conducted to evaluate the impact of various nitrogen and phosphorus levels along with beneficial microbes to enhance canola productivity. The research was carried out at Agronomy Research Farm, The University of Agriculture Peshawar in winter 2016-2017. The experiment was conducted in randomized complete block factorial design. The study was comprised of three factors including nitrogen (60, 120 and 180 kg ha-¹), phosphorous (70, 100 and 130 kg ha-¹) and beneficial microbes (with and without BM). A control treatment with no N, P and BM was also kept for comparison. Application of beneficial microbes significantly increased pods plant, seed pod, seed filling duration, 1000 seed weight, biological yield and seed yield as compared to control plots. Nitrogen applied at the rate of 180 kg ha-¹ increased pods plant-¹, seed pod, seed filling duration, seed weight, biological yield and seed yield. Maximum pods plant-¹, seed pod, early seed filling, heavier seed weight, biological yield, seed yield, and harvest index were observed in plots treated with 130 kg.ha-¹ phosphorous. As comparison, the combine treated plots have more pods plant-¹, seeds pod-¹, seed filling duration, heaviest seeds, biological yield, seed yield and harvest index as compared to control plots. It is concluded that application of beneficial microbes with N and P at the rate of 180 kg ha-¹ and 130 kg ha-¹, respectively, increased yield and its attributes for canola.
Uma pesquisa foi realizada para avaliar o impacto de vários níveis de nitrogênio e fósforo, juntamente com micróbios benéficos, para aumentar a produtividade da canola. A pesquisa foi realizada no inverno de 2016-17 no Agronomy Research Farm, Universidade de Agricultura do Peshawar. O experimento foi conduzido por planejamento fatorial aleatorizado em blocos. O estudo focou-se em três fatores, incluindo o teor de nitrogênio, N, (60, 120 e 180 kg.ha-¹), o teor de fósforo, P, (70, 100 e 130 kg ha-¹) e a presença de micróbios benéficos (com BM e sem BM). Para fins de comparação, um tratamento controle sem N, P e BM também foi incluído no estudo. A aplicação de micróbios benéficos aumentou significativamente as vagens das plantas e de sementes, a duração do enchimento das sementes, o peso de 1000 sementes, o rendimento biológico e o rendimento de sementes em comparação com os resultados do controle. O nitrogênio aplicado na taxa de 180 kg ha-¹ aumentou as vagens por planta, vagem, duração do enchimento, peso da semente, rendimento biológico e rendimento de sementes. Vagens máximas por planta, vagem, enchimento precoce de sementes, peso maior de semente, rendimento biológico, rendimento de sementes e índice de colheita foram observados em parcelas tratadas com 130 kg.ha-¹ de fósforo. Em comparação aos blocos cultivados de controle, os blocos cultivados tratados combinados têm mais vagens por planta e sementes por vagem, maior duração do enchimento das sementes, maior número de sementes mais pesadas e maior rendimento biológico, rendimento de sementes e índice de colheita. Conclui-se que a aplicação de micróbios benéficos junto com N e P nas doses de 180 kg ha-¹ e 130 kg ha-¹, respectivamente, aumentou a produtividade e atributos de produtividade para a canola.

@#Trypanothione reductase is a key enzyme that upholds the redox balance in hemoflagellate protozoan parasites such as T. congolense. This study aims at unraveling the potency of Kolaviron against trypanothione reductase in T. congolense infection using Chrysin as standard. The experiment was performed using three different approaches; in silico, in vitro and in vivo. Kolaviron and Chrysin were docked against trypanothione reductase, revealing binding energies (-9.3 and -9.0 kcal/mol) and Ki of 0.211μM and 0.151μM at the active site of trypanothione reductase as evident from the observed strong hydrophobic/hydrogen bond interactions. Parasitized blood was used for parasite isolation and trypanothione reductase activity assay using standard protocol. Real-time PCR (qPCR) assay was implored to monitor expression of trypanothione reductase using primers targeting the 177-bp repeat satellite DNA in T. congolense with SYBR Green to monitor product accumulation. Kolaviron showed IC50 values of 2.64μg/ml with % inhibition of 66.78 compared with Chrysin with IC50 values of 1.86μg/ml and % inhibition of 53.80. In vivo studies following the administration of these compounds orally after 7 days post inoculation resulted in % inhibition of Chrysin (57.67) and Kolaviron (46.90). Equally, Kolaviron relative to Chrysin down regulated the expression trypanothione reductase gene by 1.352 as compared to 3.530 of the infected group, in clear agreement with the earlier inhibition observed at the fine type level. Overall, the findings may have unraveled the Kolaviron potency against Trypanosoma congolense infection in rats.
ABSTRACT
ABSTRACT Background: Roux-en-Y gastric bypass (RYGB) has been the choice of bariatric procedure for patients with symptomatic reflux - and is known to be effective in reducing the need for anti-reflux medication postoperatively. However, a small number of RYGB patients can still develop severe reflux symptoms that require a surgical intervention. Aim: To examine and describe the patient population that requires an anti-reflux procedure after RYGB evaluating demographics, characteristics, symptoms and diagnosis Methods: A retrospective chart review was performed on 32 patients who underwent a hiatal hernia repair and/or Nissen fundoplication after RYGB Jul 1st, 2014 and Dec 31st, 2019. Patients were identified using the MBSAQIP database and their electronic medical records were reviewed. Results: Most patients were female (n=29, 90.6%). The mean age was 52.8 years and the mean body mass index (BMI) was 34.1 kg/m2 at the time of anti-reflux procedure. Patients underwent the anti-reflux procedure at a mean of 7.9 years after the RYGB procedure. The mean percentage of excess BMI loss during the time between RYGB and anti-reflux procedure was 63.4%. Conclusions: Female patients with a significant weight loss may develop a severe reflux symptoms years after RYGB. Complaints of reflux after RYGB should not be overlooked. Careful follow-up and appropriate treatment (including surgical intervention) is needed for this population.
RESUMO Racional: O bypass gástrico em Y-de-Roux (RYGB) tem sido o procedimento bariátrico de escolha para pacientes com refluxo sintomático - e é conhecido por ser eficaz na redução da necessidade de medicação anti-refluxo no pós-operatório. No entanto, um pequeno número de pacientes com RYGB ainda pode desenvolver sintomas de refluxo graves que requerem uma intervenção cirúrgica. Objetivo: Examinar e descrever a população de pacientes que requer procedimento anti-refluxo após RYGB avaliando dados demográficos, características, sintomas e diagnóstico. Métodos: Revisão retrospectiva de prontuários foi realizada em 32 pacientes submetidos a hérnia hiatal e / ou fundoplicatura Nissen após RYGB em 1º de julho de 2014 a 31 de dezembro de 2019. Os pacientes foram identificados por meio do banco de dados MBSAQIP e seus prontuários eletrônicos foram revisados. Resultados: A maioria dos pacientes era do sexo feminino (n = 29 - 90,6%). A média de idade foi de 52,8 anos e o índice de massa corporea (IMC) médio de 34,1 kg / m2 na época do procedimento anti-refluxo. Os pacientes foram submetidos ao procedimento anti-refluxo em média 7,9 anos após o procedimento do BGYR. A porcentagem média de perda do excesso de IMC durante o tempo entre o BGYR e o procedimento anti-refluxo foi de 63,4%. Conclusões: Pacientes do sexo feminino com perda de peso significativa podem desenvolver sintomas graves de refluxo anos após o BGYR. Sintomas de refluxo após RYGB não devem ser negligenciadas. Acompanhamento cuidadoso e tratamento adequado (incluindo intervenção cirúrgica) são necessários para essa população.

Background: Stroke is one of the leading causes of mortality and morbidity worldwide. In this study, authors worked on clinical presentation and types of stroke. The two main types of strokes are ischemic and haemorrhagic. Brain infarction is caused by decrease blood flow due to either narrowing of artery or complete obstruction to blood flow owing to embolism. While haemorrhage is caused by rupture of artery or aneurysms leading to accumulation of blood in the brain parenchyma.Methods: Cross sectional study of group of patients in Nishtar hospital Multan, Pakistan who presented with variety of neurological symptoms who were subsequently diagnosed as non-traumatic stroke. All patients were subjected to a detailed history and thorough clinical examination and investigations after obtaining informed consent.Results: Of 122 patient, 66 patients were male and 56 were female. Ischemic stroke was more common: present in 76 patients as compared to 46 patients with hemorrhagic stroke. Hypertension was present in 40.9% of ischemic stroke and 27.8% of hemorrhagic strokes. Most of the patients (67.2%) had altered sensorium at presentation followed by hemiplegia in 39.3 % of patients.Conclusions: Prevalence of ischemic strokes is higher than that of haemorrhagic stroke. Hypertension is associated with both types of these strokes. Moreover, hyperglycaemia and high blood pressure are common in early phase of stroke. Vomiting in stroke favors haemorrhagic stroke.
ABSTRACT
Background: To find out the causes of Acute Kidney Injury (AKI) in population.Methods: A total of 150 patients were enrolled from medical, surgical, gynecology and obstetrics units of Allied Hospital and Madinah Teaching Hospital, Faisalabad, Pakistan. History, physical examination and investigations were recorded on specially designed proforma. Patients were evaluated to find out the etiologies of AKI. All patients were subjected to urine analysis, complete blood count, blood biochemistry (urea, creatinine, electrolytes, uric acid, calcium and phosphorus) and ultrasound scan of the abdomen and pelvis. Renal biopsy, immunological assays, such as hepatitis B surface antigen, anti-hepatitis C virus antibody, complements level, antinuclear antibody, anti-double-stranded DNA, anti-neutrophil cytoplasmic antibody and anti-glomerular basement membrane antibody were performed in selected cases.Results: Male (36%) and female (64%). Pre-renal AKI was most common and was reported in 80 patients (53.33%). Intrinsic Renal azotemia in 56 patients (37.33%). Post renal azotemia in 14 patients (9.33%). Among 80 patients of prerenal AKI, hemorrhage in 45(56.25%), gastroenteritis in 16(20%), sepsis in 8(10%), cardiac diseases in 4(5%), hepatorenal syndrome in 3 (3.75%), peritonitis in 2 (2.50%) and burns in 2(2.50%) were the main causes of Pre-renal AKI. Among 56 patients of intrinsic renal AKI, 40(71.4%) had acute tubular necrosis (ATN), 12(21.4%) with multifactorial causes and 4(7.14%) were found to have glomerulonephritis. Among 14 patients of post renal AKI, 6(42.9%) were having calculi, 6(42.9%) were to have enlarged prostate and 2(4.3%) were having stricture urethra. In this study, contribution of obstetrical, medical and surgical etiologies were recorded as 40%, 36% and 20% respectively.Conclusions: In contrast to study reported from neighbouring country, this study shows rather increase in pregnancy related AKI.

ABSTRACT
Background: Diabetes is not uncommon in patients requiring cardiac surgery. These patients have a higher incidence of morbidity and mortality. Subsequently, diabetes represents a major medico-economic problem in both developed and developing countries. This study was designed to observe the association between glycemic control and outcome of patients after open heart surgery in adult population. Materials and Methods: Data was collected retrospectively in all patients who underwent open cardiac surgery (coronary artery bypass grafting, valve, or bypass grafting with valve surgery) and survived 72 hours postoperatively and had diabetes. The study was conducted from January 2015 to December 2016. Results: Of the 129 patients included in the study, male dominated 101 (78.3%). Most frequent surgery was coronary artery bypass grafting (CABG) 123 (95.3%), CABG plus aortic valve replacement 4 (3.1%), and CABG plus mitral valve replacement 2 (1.6%). Considering diabetes, only 3 (2.3%) were on diet control, 112 (86.8%) on oral hypoglycemic agents (OHA), whereas 9 (7%) had control on both insulin and OHA. Only 5 (3.9%) had type I diabetes. The mean fasting blood sugar (FBS) was 154.58 g/dl, and the mean duration of diabetic mellitus was observed 12.32 years. Microvascular and macrovascular complications were 26/129 (20.16%) and 17/129 (13.17%), respectively. Total 75 (58.1%) patients did not require insulin and 54 (41.9%) were treated with insulin intraoperatively to keep the blood glucose level less than 200 g/dl. Cardiac arrhythmias were frequent in the insulin group (P < 0.05), which was also associated with increased stay in the cardiac intensive care unit. Conclusion: Inadequate glycemic control during open cardiac surgery can possibly lead to increased perioperative morbidity and mortality and with decreased long-term survival and recurrent ischemic events. Therefore, aiming for blood glucose levels around 140 mg/dl appears reasonable. Further studies are required to define specific glucose ranges for a clearer definition of recommended blood glucose goals in postoperative cardiac patients for the best outcomes in patients with diabetes mellitus.
ABSTRACT
Objective: To determine the role of toll-like receptor 4 (TLR-4) in eliciting cellular and humoral immune responses against recombinant Mycobacterium bovis bacille Calmette-Guérin (rBCG) expressing the C-terminus of merozoite surface protein-1 of Plasmodium falciparum. Methods: Six groups of mice (n=6 per group) were injected with phosphate buffered saline T80, BCG or rBCG intraperitoneally, in the presence or absence of a TLR-4 inhibitor; TAK-242. Enzyme-linked immunosorbent assay was carried out for serum total IgG, IgG1, IgG2a and IgG2b determination. Spleens were also harvested and splenocytes cultured for determination of intracellular cytokines; IL-4 and IFN-γ via enzyme-linked immunosorbent assay. Results: The production of total IgG, and the subclasses IgG1, IgG2a and IgG2b was significantly higher in rBCG-immunised mice than BCG and phosphate buffered saline immunised mice in the absence of TAK-242. A significant rise in total IgG occurred with more booster immunisations. The level of IgG2a was highest, followed by IgG2b, then IgG1. The production of both IL-4 and IFN-γ was also highest in the rBCG immunised groups. These significant rises were inhibited in the presence of TAK-242. Conclusions: We present evidence of the role of TLR-4 in the increased production of total IgG, IgG1, IgG2a and IgG2b, as well as IL-4 and IFN-γ in response to our rBCG construct.
ABSTRACT
Background:Hydatidosis is a zoonotic parasitic disease and a serious human and animal health problem in many endemic areas of the world. It is caused by the tapeworm parasite of Echinococcus granulosus sensu lato. This parasite is endemic in the neighboring countries like China, Iran and India. There are limited studies on CE in Pakistan.Methods:This study primarily aimed to determine the prevalence of hydatidosis in slaughtered livestocks in Chakwal district (Chakwal, Bhaun, Kallar kahar, Choa saidan shah and Balkasar) from June to December 2015. The livestocks were inspected after slaughtering and the ages, breeds and organ wise prevalence were recorded.Results:A total of 6 095 animals (sheep, goat, buffaloes and cattle) of different genders, ages and breeds were inspected after slaughtering. Overall prevalence was 8.55% (88/1 045) in sheep followed by 8.42% (88/1 045), 6.90% (4/58), 2.99% (138/4 608) in cattle, buffaloes and goats, respectively. Liver wise prevalence was 7.75%, 6.90%, 0.06%, 1.30% in cattle, buffaloes, goats and sheep, respectively while lung wise prevalence was 7.55%, 0.67%, 0.00%, 0.00%, in sheep, cattle, buffaloes and goats, respectively. Male (9.50%) were more infected than female (1.96%) in all hosts. Breed wise prevalence was higher in desi breed of cattle followed by crossbreed and other breeds. In goats, teddhi breed was more infected then beetal while in sheep Afghani breed was more infected than the others. Cattle of 6-9 years groups were more infected than 0-3 and 3-6 years age groups. Buffaloes of the only age group of 6-9 years were infected while in goat and sheep 3-6 years were more infected than 0-3 years. According to the statistical analysis there was a significant difference (P<0.05) in prevalence of hydatidosis when ages, genders and organs were compared.Conclusion:The hydatidosis is a serious parasitic problem in the study area for livestocks. The disease should be monitored on regular basis in other areas of Pakistan and future studies should be carried out to explore the real prevalence in Pakistan.
ABSTRACT
Objectives:To detect Leishmania species in human patients, animal reservoirs and Phlebotomus sandflies in Waziristan, Pakistan.Methods:Tissue smears and aspirates from 448 cutaneous leishmaniasis (CL) suspected patients were analyzed. To sort out role of the reservoir hosts, skin scrapings, spleen and liver samples from 104 rodents were collected. Furthermore, buffy coat samples were obtained from 60 domestic animals. Sandflies were also trapped. All human, animals and sandfly samples were tested by microscopy, kinetoplastic PCR and internal transcribed spacer 1 (ITS1) PCR followed by restriction fragment length polymorphism for detection of Leishmania species.Results:An overall prevalence of 3.83% and 5.21% through microscopy and ITS1 PCR respectively was found. However, the statistically non-significant correlation was found between area, gender, and number of lesions. The presence of rodents, sandflies, domestic animals and internally displaced people increased the risk of CL. Using ITS1-PCR-RFLP, Leishmania tropica (L. tropica) was confirmed in 106 samples while 25 of the isolates were diagnosed as Leishmania major (L. major). Similarly, 3/104 rodents were positive for L. major and 14 pools of DNA samples containing Phlebotomus sergenti sandflies were positive for L. tropica. None of samples from domestic animals were positive for leishmaniasis.Conclusions:In the present study, L. tropica and L. major are found to be the main causative agents of CL in study area. Movement of internally displaced people from CL endemic areas presents a risk for nearby CL free areas. To the best of our knowledge, we report for the first time L. major infection in rodents (Rattus rattus) and L. tropica in Phlebotomus sergenti sandflies trapped in Waziristan, Pakistan.
ABSTRACT
BACKGROUND: The objevctive of the present study was to explore the potential influence of blood markers and patient factors such as risk factors, kidney function profile, coagulation profile, lipid profile, body mass index, blood pressure, and vein diameter on the maturation of arteriovenous fistula (AVF) in patients with end-stage renal disease. METHODS: Retrospective data from 300 patients who had undergone AVF creation at the Royal Infirmary of Edinburgh were examined. A predictive logistic regression model was developed using a backward stepwise procedure. Model performance, discrimination, and calibration were assessed using the receiver operating characteristic (ROC) curve and Hosmer–Lemeshow goodness-of-fit test. The final model was externally validated by 100 prospective patients who received a new fistula at the Royal Infirmary of Edinburgh. RESULTS: A total of 400 (300 retrospective and 100 prospective) patients were recruited for this study, with a mean age of 60.14 ± 15.9 years (development set) and 58 ± 15 years (validation set), respectively (P = 0.208). Study results showed that males were twice as likely to undergo fistula maturation as females, while patients with no evidence of peripheral vascular disease (PVD) were three times more likely to mature their fistula and a preoperative vein diameter > 2.5 mm resulted in a fivefold increase in fistula maturation as compared with a vein size of less than 2.5 mm. The model for fistula maturation had fair discrimination, as indicated by the area under the ROC curve (0.68), but good calibration as indicated by the Hosmer–Lemeshow test (P = 0.79). The area under the receiver operating curve for the validation model in the validation set was 0.59. Similarly, in the validation set, the Hosmer–Lemeshow statistic indicated an agreement between the observed and predicted probabilities of maturation (P > 0.05). CONCLUSION: Gender, PVD, and vein size are independent predictors of AVF maturation. The clinical utility of these risk categories in the maturation of AVF requires further evaluation in longer follow-up.

Low birthweight [LBW] remains a significant public health problem in Pakistan and further understanding of factors associated with LBW is required. We conducted a hospital-based matched case control study to identify risk factors associated with LBW in a rural district of Pakistan. We found that illiteracy [AOR: 2.68; 95% CI: 1.59 - 4.38], nulliparity [AOR: 1.82; 95% CI: 1.26-2.44], having a previous miscarriage/abortion [AOR: 1.22; 95% CI: 1.06-2.35], having < 2 antenatal care [ANC] visits during last pregnancy [AOR: 2.43; 95% CI: 1.34-2.88], seeking ANC in third trimester [AOR: 3.62; 95% CI: 2.14-5.03], non-use of iron folic acid during last pregnancy [AOR: 2.72; 95% CI: 1.75-3.17], having hypertension during last pregnancy [AOR: 1.42; 95% CI: 1.13-2.20], being anemic [AOR: 2.67; 95% CI: 1.65-5.24] and having postpartum weight of <45 kg [AOR: 3.30; 95% CI: 1.97-4.52] were significantly associated with an increased odds of having a LBW baby. Our study identifies modifiable risk factors requiring immediate commitment from the health authorities

The growing proportion of individuals suffering from chronic kidney disease has considerable repercussions for both kidney specialists and primary care. Progressive and permanent renal failure is most frequently treated with hemodialysis. The efficiency of hemodialysis treatment relies on the functional status of vascular access. Determining the type of vascular access has prime significance for maximizing successful maturation of a fistula and avoiding surgical revision. Despite the frequency of arteriovenous fistula procedures, there are no consistent criteria applied before creation of arteriovenous fistulae. Increased prevalence and use of arteriovenous fistulae would result if there were reliable criteria to assess which arteriovenous fistulae are more likely to reach maturity without additional procedures. Published studies assessing the predictive markers of fistula maturation vary to a great extent with regard to definitions, design, study size, patient sample, and clinical factors. As a result, surgeons and specialists must decide which possible risk factors are most likely to occur, as well as which parameters to employ when evaluating the success rate of fistula development in patients awaiting the creation of permanent access. The purpose of this literature review is to discuss the role of patient factors and blood markers in the development of arteriovenous fistulae.
