Hepatitis C virus is a bloodborne virus and the major cause of chronic hepatitis, cirrhosis and hepatocellular carcinoma. Viral load is the prognostic marker of the disease progression. The aim of this study is to determine the correlation of hepatitis C RNA load with antiviral therapy and its risk factors among the HCV seropositive patients. This study will be helpful in early assessment of the disease progression and its complications.The blood samples were collected over a period of one year from April 2022-March 2023. The serum was subjected to ELISA for Anti HCV Ab. Viral load quantification was done by MylabPathoDetect HCV Quantitative PCR Kit in HCV seropositive patients.About 18,882 patients were tested for HCV infection over a period of one year. 75 patients were positive for HCV infection. Prevalence of HCV was 0.39. The mean viral load was reduced from 3.08×10 IU/ml to 1.98×10 IU/ml and Sustained Viral Response (SVR12) was achieved in 63(84%) patients after effective treatment with direct acting antiviral agents. High risk sexual behavior was the most common risk factor observed in seropositive patients.The current study determines the reduction in mean viral load and achieving sustained viral response after the effective antiviral therapy at the earliest, which is helpful in prevention of disease progression and its complications.

The main objective of this study was to identify, analyze, and evaluate the bacteriological profile and antimicrobial susceptibility patterns of symptomatic urinary tract infections (UTIs) among patients at Idlib University Hospital in Northwest Syria. By isolating and characterizing the uropathogens, the study aimed to gain insights into their current antimicrobial susceptibilities. This information is crucial in order to combat the increasing antibiotic resistance and provide effective treatment options for UTIs, which are prevalent both in the community and hospital settings.This observational research took place at Idlib University Hospital in Northwest Syria spanning from June 2022 to December 2023. Our study involved 320 patients exhibiting symptoms of UTI (68.4% females and 31.6% males). Urine samples were cultured to identify the microorganisms responsible for UTI. Biochemical tests were employed to identify the isolated bacteria, while the antimicrobial susceptibility was determined through disk diffusion susceptibility testing. Our study found to be the leading cause of UTIs, accounting for 58.4% of cases, followed by spp. Gram-negative bacteria comprised 85% of isolated strains. The 13–65 age group showed the highest UTI susceptibility (41.3%). High resistance was observed to ampicillin/sulbactam, cefotaxime, ceftriaxone, and co-trimoxazole. Conversely, minimal resistance was noted against Meropenem, Imipenem, Gentamicin, and Levofloxacin.This research highlights the prevalence of antibiotic-resistant infections within the hospital under study. Hence, there is an imperative to enhance the efficiency of comprehensive infection control initiatives to effectively handle and regulate hospital-acquired infections caused by highly resistant microorganisms.
本研究的主要目的是识别、分析和评估叙利亚西北部伊德利卜大学医院无症状尿路感染(UTI)患者的细菌学特征和抗菌药敏感性模式。通过分离和鉴定尿路病原体,该研究旨在深入了解这些病原体目前的抗菌药敏感性。这些信息对于应对日益增长的抗生素耐药性以及为社区和医院中普遍存在的UTI提供有效的治疗方案至关重要。这项观察性研究于2022年6月至2023年12月在叙利亚西北部的伊德利卜大学医院进行。我们的研究涉及 320 名出现尿毒症症状的患者(68.4% 为女性,31.6% 为男性)。我们对尿液样本进行了培养,以确定导致尿毒症的微生物。生化检验用于鉴定分离出的细菌,而抗菌药敏感性则通过磁盘扩散药敏试验确定。我们的研究发现,革兰氏阴性菌占分离菌株的 85%,是UTI 的主要病因,占病例的 58.4%。13-65 岁年龄组对 UTI 的敏感性最高(41.3%)。对氨苄西林/舒巴坦、头孢他啶、头孢曲松和共三唑的耐药性较高。与此相反,对美罗培南、亚胺培南、庆大霉素和左氧氟沙星的耐药性极低。因此,当务之急是提高综合感染控制措施的效率,以有效处理和控制由高度耐药微生物引起的院内感染。

:  Methicillin-resistant (MRSA) remains to be the most concerned pathogen with enhanced multi-drug resistance in clinical set-ups. With an immediate need to control MRSA infection, there is a steep rise in the use of mupirocin as a decolonization regime.:  A total of 65 MRSA samples were analysed in the present study. infection identified by standard conventional phenotypic methods. The antibiotic susceptibility pattern of mupirocin (5 μg/ml) was found using Kirby Bauer’s disc diffusion method and the minimum inhibitory concentration (MIC) determined using MIC E-test strips of mupirocin.:  All the bacterial strains presented with MIC value less than 4 μg/ml, 23 isolates falls in the range of 0.05 μg/ml and 0.19 μg/ml, 12 strains MIC ranged between 0.125 and 0.640 μg/ml. However, five MRSA isolates showed no zone against mupirocin E-strip.:  In present study, 92% of isolates were sensitive to mupirocin, this gives hope that mupirocin can be promising in the elimination of MRSA strains, a major concern in clinical practice. Also, the use of 5µg mupirocin discs is economical as compared to mupirocin E-strips, mupirocin discs can be used in a low resourceful clinical setups. However, our study revealed no difference in sensitivity for both the E-strip and disc method.
: 耐甲氧西林(MRSA)仍是临床上最令人担忧的病原体,其多重耐药性增强。由于急需控制 MRSA 感染,使用莫匹罗星作为去污剂的情况急剧增加。 本研究共分析了 65 份 MRSA 样本,并通过标准的传统表型方法确定了感染情况。使用 Kirby Bauer 盘扩散法测定了莫匹罗星(5 μg/ml)的抗生素敏感性模式,并使用莫匹罗星 MIC E 测试条确定了最低抑菌浓度(MIC): 所有细菌菌株的 MIC 值均小于 4 μg/ml,23 个分离菌株的 MIC 值介于 0.05 μg/ml 和 0.19 μg/ml 之间,12 个菌株的 MIC 值介于 0.125 和 0.640 μg/ml 之间。然而,有 5 株 MRSA 分离物对莫匹罗星电子条无耐受区: 在本研究中,92%的分离株对莫匹罗星敏感,这使人们看到了莫匹罗星在消除 MRSA 菌株方面的希望,而这正是临床实践中的一个主要问题。此外,与莫匹罗星电子药条相比,使用 5µg 莫匹罗星药片更为经济,因此莫匹罗星药片可用于资源匮乏的临床环境中。不过,我们的研究表明,电子药条和药盘法的敏感性没有差异。

: Carbapenem-resistant  (CRE) are major organisms amongst the critical group of drug-resistant bacteria and are associated with high morbidity and mortality. With limited treatment options, the detection and characterization of carbapenemase is important for appropriate management. This study aims to characterize carbapenemase produced by  using combined disk test and their molecular profiling. : All carbapenem-resistant isolated from various clinical samples were included in the study. Carbapenemase production was characterized by observing synergy on combining meropenem disk with beta-lactamase inhibitors like phenylboronic acid, EDTA, and cloxacillin, following which genetic profiling was done using multiplex PCR.: Out of 445  isolated, 104 (23.4%) were carbapenem-resistant. The most common CRE isolated was  (62 out of 104) followed by  (40 out of 104) and 2 out of 104 CRE isolates were  species. Co-production of NDM and OXA-48-like enzymes (39.4%) was the most common mechanism followed by NDM alone (19.2%) and OXA-48 alone (16.3%). NDM was the most common gene detected overall with 72 out of 104 CRE (69.2%) isolates showing its presence, followed by OXA-48 present in 63 of 104 (60.6%) isolates.: Metallo-beta-lactamases (NDM) was the predominant type of carbapenemase gene detected among the isolates, with the co-production of NDM and OXA-48 enzymes being the most common mechanism of resistance.

: The prevalence of Rifampicin-resistant MTB/EPTB in children in India is a growing concern. Globally a large proportion of childhood tuberculosis (TB) cases are diagnosed based only on clinical findings. This study was undertaken to measure MTB positivity and their rifampicin resistance rates in different clinical samples from children. : Different samples of clinically suspected tuberculosis in children were included. All the samples were tested for Tuberculosis positivity and Rifampicin (Rif) resistance by GeneXpert assay. A total of 1420 samples were received from presumptive TB patients of all age group from February 2023 to January 2024. Total 1420 samples were analyzed for this study, of which 30% were male and 70% were females. Respiratory samples and extra-pulmonary samples were 1261 (88.8%) and 159 (11.2%) respectively. Among 1420, 211(14.86%) samples were from children and among these 75 (35.55%) were found MTB positive and 7 (9.33%) were Rif resistant MTB. Of 75 MTB detected patients, 77.8% and 22.2% MTB detected in female and male children respectively. There are higher prevalence of Rif resistant MTB in children so it is important for healthcare providers in India to be vigilant in timely diagnosis, individualized treatment and enhance surveillance. It is essential to combat this growing threat and protect the health of children.
:印度儿童对利福平耐药的 MTB/EPTB 感染率日益令人担忧。在全球范围内,很大一部分儿童结核病(TB)病例仅根据临床结果进行诊断。本研究旨在检测不同儿童临床样本中 MTB 阳性率及其对利福平的耐药率。 研究对象:临床疑似结核病儿童的不同样本。所有样本均通过 GeneXpert 检测法进行结核菌阳性和利福平(Rif)耐药性检测。从 2023 年 2 月至 2024 年 1 月,共收到 1420 份来自各年龄组推定肺结核患者的样本。本研究共分析了 1420 份样本,其中 30% 为男性,70% 为女性。呼吸道样本和肺外样本分别为 1261 份(88.8%)和 159 份(11.2%)。在 1420 份样本中,211 份(14.86%)来自儿童,其中 75 份(35.55%)发现 MTB 阳性,7 份(9.33%)是对利福耐药的 MTB。在检出 MTB 的 75 名患者中,女性和男性分别占 77.8%和 22.2%。对利福夫耐药的 MTB 在儿童中的流行率较高,因此印度的医疗保健提供者必须提高警惕,及时诊断、个性化治疗并加强监测。应对这一日益严重的威胁和保护儿童健康至关重要。

: To isolate and detect a Newcastle disease virus in commercial poultry, Molecular characterization and phylogenetic analysis of the confirmed isolate and Multiple sequence alignment and achievement of accession numbers against our submissions in NCBI bankit.: Genetic and antigenic diversity in the fusion protein gene of New Castle disease virus strains has been recognized and the progressive changes over sequential years indicate that it is a continuously evolving virus. The current vaccines containing conventional vaccinal strains can protect birds to a certain level but do not prevent infection and virus shedding. : The partial fusion protein gene of the 14 NDV isolates during the 2023 outbreaks from different areas of Pakistan was determined and analyzed. The antigenic protein translational segment of the fusion gene nucleotide fragment was targeted with a specifically designed primer executed 202 bp size of predictable amplicon during PCR amplification. The nucleotide sequence analysis of studied isolates showed closed similarity to the NCBI bankit numbers. Phylogenetic analysis revealed that 3 isolates belong to genotype II while, 2 isolates positions near genotype VIII of class II. The 6 isolates were located near genotype XVII and only 1 was presented on genotype V branch in calss II. Mutation analysis results revealed various mutations at nucleotide intervals and even found altered amino acids during translation. The results revealed that nucleotide mutation at various positions attributes amino acid substitution that enables wild prevailing strains to evade artificial active immunity. In such a scenario Chimeric and genotype match vaccines prepared from indigenous isolates may be useful in developing candidate vaccines to prevent virus shedding and infection. Further studies are suggested at molecular level to determine the consensus amino acid sequence for virulent, mesogenic, and avirulent prevailing NDV strains.
:分离并检测商业家禽中的新城疫病毒,对确证分离株进行分子特征鉴定和系统发育分析,并根据我们在 NCBI 数据库中提交的数据进行多序列比对并获得加入号:新城疫病毒毒株融合蛋白基因的遗传和抗原多样性已得到确认,连续多年的渐进变化表明这是一种不断进化的病毒。目前含有传统疫苗毒株的疫苗可以在一定程度上保护鸟类,但不能防止感染和病毒脱落。 研究人员测定并分析了 2023 年巴基斯坦不同地区暴发的 14 个新城疫病毒分离株的部分融合蛋白基因。在 PCR 扩增过程中,使用专门设计的引物针对融合基因核苷酸片段的抗原蛋白翻译片段执行了 202 bp 大小的可预测扩增片段。研究分离物的核苷酸序列分析表明与 NCBI bankit 编号非常相似。系统进化分析表明,3 个分离株属于基因型 II,2 个分离株位于基因型 VIII 的 II 类附近。6 个分离株位于基因型 XVII 附近,只有 1 个出现在基因型 V 分支中。突变分析结果显示了核苷酸间的各种突变,甚至发现了翻译过程中氨基酸的改变。结果表明,不同位置的核苷酸突变会导致氨基酸置换,从而使野生菌株能够逃避人工主动免疫。在这种情况下,从本地分离株制备的嵌合疫苗和基因型匹配疫苗可能有助于开发候选疫苗,以防止病毒脱落和感染。建议在分子水平上开展进一步研究,以确定毒性、中毒性和无毒性流行 NDV 株系的共识氨基酸序列。

The current vaccines containing conventional vaccinal strains can protect birds to a certain level but do not prevent infection and virus shedding. : The partial fusion protein gene of the 14 NDV isolates during the 2023 outbreaks from different areas of Pakistan was determined and analyzed.

: Hand hygiene (HH) holds a pivotal role in infection control. However, compliance with hand hygiene has remained low worldwide. Hospital Acquired Infection (HAI) incidence is rising in most healthcare facilities. It is postulated that around 30% of HAI can be reduced by following strict hand hygiene protocols by healthcare workers (HCWs). This study was done to evaluate the level of compliance of healthcare personnel in our tertiary care hospital with respect to appropriate hand hygiene practices by employing HH audits. A cross-sectional observational study was conducted in a tertiary care teaching hospital over six months. A single‑ observer direct observation technique was used to collect the HH compliance data conducted by trained Infection control nurses. HCWs, including doctors, nurses, CRMIs and technicians, were observed for compliance in all the critical areas, outpatient and inpatient sections across all departments. The HH audit form designed based on the WHO's HH audit tool kit was used in the study. The audits were conducted randomly in all the areas for at least 20 minutes per day. : A total of 583 HCWs were observed for the Hand Hygiene Compliance audit. The overall HH compliance rate was 67.88%, with doctors at 74.31%, followed by nurses at 70.42%. Compliance was observed in OBG/Labour ward at 78.7% and the oncology ward at 78.5%. WHO moments-specific hand hygiene adherence showed the least compliance rate of 55% for moment 1, followed by moment 5 with 58.9%. Best compliance was observed for moment 3, with 79.2%.: The overall hand hygiene compliance was comparatively better in our study. Specific measures such as improved facilities, training and monitoring are needed to attain good H`H compliance.
:手部卫生(HH)在感染控制中起着举足轻重的作用。然而,在全球范围内,手部卫生的依从性仍然很低。在大多数医疗机构中,医院获得性感染(HAI)的发生率正在上升。据推测,如果医护人员(HCWs)严格遵守手部卫生规范,可减少约 30% 的 HAI。本研究旨在通过手部卫生审计,评估我们这家三级医疗保健医院的医护人员遵守适当手部卫生规范的程度。这项横断面观察研究在一家三级护理教学医院进行,历时六个月。经过培训的感染控制护士采用单一观察者直接观察法收集手卫生依从性数据。包括医生、护士、CRMIs 和技术人员在内的医护人员在所有关键区域、门诊和住院部的所有部门接受了符合性观察。研究中使用了根据世界卫生组织卫生保健审核工具包设计的卫生保健审核表。审核在所有区域随机进行,每天不少于 20 分钟。 手部卫生合规性审核:共有 583 名医护人员接受了手部卫生合规性审核。总体手卫生达标率为 67.88%,其中医生为 74.31%,护士为 70.42%。妇产科/产科病房的合规率为 78.7%,肿瘤科病房为 78.5%。世卫组织特定时刻手卫生依从性显示,时刻 1 的依从性最低,为 55%,其次是时刻 5,为 58.9%。手卫生依从性最好的是时刻 3,为 79.2%:在我们的研究中,总体手卫生依从性相对较好。要达到良好的手卫生依从性,需要采取具体措施,如改善设施、培训和监测。

Bloodstream infections (BSI) due to multidrug-resistant organisms from paediatric setup have become increasingly common. BSI can be transient and be rapidly cleared out by the host defence mechanism or be associated with high morbidity and mortality if it becomes persistent.Blood samples were collected from 1112 children within a 1-year study period (July 2022 to June 2023) which included all children admitted with complaint of fever and suspected of having sepsis in Paediatric department of Shri Chhatrapati Shivaji Maharaj Sarvopchar Rugnalaya (SCSMSR), Solapur. Blood volume was collected depending upon age and body weight of the patient with aseptic precautions and inoculated in Brain Heart Infusion broth (BHI) which was incubated at 37°C for 7 days. Subcultures were made on blood agar and MacConkey agar plates. Organisms were identified by biochemical reactions and antibiotic susceptibility test of the isolates were performed by disk diffusion. Out of 1112 suspected cases, 175 (15.74%) were culture positive. (27.43%) was the most common isolate followed by (16.57%) Most common Gram positive isolate was (11.43%) followed by (6.86%). Total Multidrug resistant (MDR) isolates in Gram negative and Gram positive were 50.35% and 31.25% respectively.High rates of antibiotic resistance are observed in both gram positive and gram negative organisms. Thus, there is an urgent need for proper implementation of antibiotic stewardship programme and infection prevention and control measures.
由儿科设置中的耐多药生物引起的血流感染(BSI)越来越常见。在为期 1 年的研究期间(2022 年 7 月至 2023 年 6 月),我们收集了 1112 名儿童的血液样本,其中包括索拉普尔 Shri Chhatrapati Shivaji Maharaj Sarvopchar Rugnalaya(SCSMSR)儿科所有主诉发烧并疑似患有败血症的儿童。根据患者的年龄和体重采集血量,并采取无菌预防措施,然后接种到脑心输液肉汤(BHI)中,在 37°C 下培养 7 天。在血琼脂和麦康凯琼脂平板上进行亚培养。通过生化反应对细菌进行鉴定,并通过磁盘扩散法对分离出的细菌进行抗生素药敏试验。在 1112 例疑似病例中,175 例(15.74%)培养呈阳性。最常见的革兰氏阳性分离菌是(27.43%),其次是(16.57%),最常见的革兰氏阳性分离菌是(11.43%),其次是(6.86%)。在革兰氏阴性和革兰氏阳性分离菌中,耐多药(MDR)菌分别占 50.35% 和 31.25%。因此,迫切需要适当实施抗生素管理计划和感染预防与控制措施。
