Abstract
INTRODUCTION Subtotal cholecystectomy (STC) is a safe approach in difficult cholecystectomies to prevent bile duct and vascular injury. However, the gallbladder remnant can become symptomatic, necessitating further surgical intervention. This study evaluates the safety profile and perioperative outcomes of remnant cholecystectomy (RC) performed under intraoperative ultrasound guidance. METHODS We retrospectively reviewed the records of all patients that underwent RC under intraoperative ultrasound guidance in 2009 and 2019. Pre-, intra- and postoperative details of patients who underwent RC were obtained from patients' electronic and paper copy records. RESULTS Ninety-seven patients underwent STC during the study period. Of this cohort, 16 patients (16.5%) presented with symptomatic gallbladder remnant over a median follow-up period of 14 months (interquartile range [IQR] 2-26). The median age was 64 years (IQR 54-69) with an equal male-to-female distribution. The median body mass index was 31kg/m2 (IQR 28-33). Twelve of 16 patients (75%) then proceeded to elective RC. Intraoperative ultrasound was used in all cases to identify the location of the remnant gallbladder and biliary anatomy. The median operative time was 88min (IQR 80-96), with 67% completed laparoscopically. No patients suffered bile duct injury. The median hospital stay was 3 days (IQR 1-5). During the follow-up period, eight patients (67%) reported symptom resolution. CONCLUSIONS RC is a safe operation that can be performed laparoscopically even after previous open subtotal cholecystectomy. We recommend the routine use of intraoperative ultrasound as an adjunct for identifying remnant gallbladder and biliary anatomy in all patients.

Abstract
Background: The rate of infertility is increasing day by day. According to studies conducted worldwide, 30 million men are diagnosed with infertility. Cases of infertility are often associated with a failure to become male in society. Procreation and gender roles are often closely linked so that infertile men are often considered the second sex. Sometimes, this condition makes men question their masculinity. Methods: We performed a systematic review and metasynthesis with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline procedure on qualitative studies on ten databases exploring the experience of infertile men and their association with masculinity. Results: Twenty-four studies matched our question, and there are two major themes with eight subthemes that were obtained from the results of the metasynthesis of these studies. The impact of this gender issue is huge on men’s health and their social interactions. As a result, gender issues provide a space for debate and a burden on men. Sometimes, men develop mental health problems. The topic of masculinity and infertility is at odds with feminism and is susceptible to the societal stigma that results from the hegemonic conception of masculinity. Interestingly, the men must accept reality and follow the treatment process for infertility, although it affects their psychological well-being. Conclusions: These findings provide insight for physicians, as treating infertility requires a multidisciplinary team that does not only address procreation issues. Social issues related to gender roles often bring patients into harmful and dangerous conditions. To address the gender issue in men globally in several dimensions, however, a large study in various populations is still required.

Abstract
OBJECTIVE The purpose of this study was to examine the sex lives of male cirrhotic patients organic factors affect them. METHOD We did an observational study of 220 cirrhotic men's satisfaction with their sexual lives. Assessment of sex satisfaction was carried out using the New Sexual Satisfaction Scale. The frequency of intercourse and masturbation was estimated. Then, the levels of albumin, total bilirubin, vitamin D, and sex steroids were examined. Ascites and sarcopenia subgroups of our patients were stratified. RESULTS Along with sex steroids, albumin, total bilirubin, and vitamin D all had an impact on how satisfying sex was (r = 0.22), (r = 0.24), and (r = -0.17) affected sex satisfaction. There were strong positive correlations between vitamin D (r = 0.33), albumin (r = 0.59), and free testosterone, along with a negative correlation between total bilirubin (r = -0.63) and free testosterone. An imbalance in sex steroid levels was observed, leading to decreased frequency of intercourse(p < 0.0001), weakened erections(p < 0.0001), and reduced quality of orgasm (p < 0.0001). Significant new sex behavior changes were found, such as an increase in masturbation. Physical limitations such as ascites and sarcopenia also impacted the decreasing sex life. CONCLUSION The sex life of cirrhotic men is affected. The decrease in the frequency of intercourse and sexual satisfaction is noticeable in male patients and leads to increased masturbation. Free Testosterone, vitamin D, albumin, and bilirubin play role in their sex life. In addition, ascites and sarcopenia not only affect their sex life but also hamper the quality of their well-being.

Abstract
Abstract
Background/Purpose
Application-based technology has been studied for patient engagement and collecting patient-reported outcomes (PROs) in several one-day surgical specialties with limited research in transcathether valve therapies program. The aim of study was to determine the effectiveness of app-based technology for collecting PROs, improving the patient experience, and reducing health services utilization in a transcatheter valve implantation (TAVI) program.
Methods
Patients accessed an interactive app via smartphones. Patients were guided from their visit to the TAVI clinic via reminders, tasks, PRO surveys, and evidence-based education. They received notifications and health surveys 2 days before the procedure to ensure they were ready for the procedure. In the postoperative period, patients were engaged with daily health surveys to track warning signs and recovery milestones for 7 days. Based on the patient's signs and symptoms, the app escalated lower risk issues to self-care education or higher risk issues to the care team (TAVI program's nurse coordinator). Follow-up surveys and Kansas City Cardiomyopathy Questionnaire (KCCQ12) were sent to patients at 1, 3, 6 and 12 months to evaluate their functional recovery. All data are reported with median and interquartile range.
Results
227 patients underwent a TAVI procedure at the MHI from December 2020 to October 2021. 99 patients (44%) accepted to use the application and formed the digital application group. The two groups (digital application group vs. non-digital application group) were comparable in terms of age (76 years old (72, 81) vs 77 years old (71,82)), STS (Society of Thoracic Surgeons' risk model) score (6,1% vs 6,7%), vascular complications (8,1 vs 7.8%) and post procedure pacemakers (10,1% vs 10.9%). In the digital application group, 93% recommended the application, 95% said it helped them feel more confident before the procedure and 84%, after the procedure. KCCQ12 score (PRO) improved from 34/70 (28, 41) at baseline to 54/70 (48,62) at 1 month after the procedure and remained stable over the 12 months. Digital application use helped to reduce emergency visits by 33.5% (7.9 vs 11.9%) and rehospitalizations related to the procedure by 50.1% (7.9% vs 15.9%) in the month following the TAVI procedure.
Conclusion
App-based technology for patient engagement is an effective modality to enhance the patient experience, better understand the trajectory of recovery, gather PRO and reduce unnecessary health services utilization in aging population of a TAVI program.

Abstract
Abstract
Background
Chemotherapy induced cognitive impairment (CICI) is a term used for the cognitive dysfunction reported with non-central nervous system cancer patients during or after chemotherapy. Recent neuroimaging studies have shown decreased activation in cancer patients during cognitive tasks post-chemotherapy. Structural changes are sought to be associated with cognitive decline in cancer survivors after chemotherapy. Here we aim to investigate the neuroimaging findings of structural abnormalities and gray matter alterations associated with chemotherapy in cancer survivors.
Material and Methods
A systematic search through PubMed database for peer-reviewed English-language studies yielded a total of 302 studies. Eligible studies were included in the activation likelihood estimation (ALE) meta-analysis if they reported coordinates in a stereotactic format (MNI or Talairach space) for voxel-based morphometric (VBM) studies on gray matter volume and post-chemotherapy cancer survivors compared to matched healthy controls. GingerALE (3.0.2) software from Brainmap.org was used to perform the ALE meta-analysis with threshold settings of uncorrected P-value < 0.001 for multiple comparisons.
Results
The study sample included 299 patients comprised of breast cancer survivors (BCS), childhood acute lymphocytic leukemia (ALL) survivors, ovarian cancer survivors (OCS) and lung cancer with 279 matched healthy controls from 12 studies and 21 experiments. ALE-maps for post-chemotherapy cancer survivors showed reduced gray matter volume in comparison to healthy controls in the left inferior frontal gyrus, right thalamus, right superior frontal gyrus, right medial frontal gyrus and right cerebellum (peak coordinates: [-43,40,-6], [23,-29,2], [14,30,55], [9,57,-16], [9,-78,-41] respectively, and cluster size of 544 mm3, 312 mm3 and 257 mm3, 296 mm3, 297 mm3 respectively).
Conclusion
This is the first ALE meta-analysis that studied the converged areas of reduced gray matter volume in post-chemotherapy cancer survivors. Our findings of reduced gray matter volume in frontal regions and cerebellum might be responsible for the cognitive dysfunction in executive function, attention, and memory observed in cancer survivors. Further studies are needed to assess the impact of different chemotherapeutic regimens related to CICI .

Abstract
A cowpea thresher that uses petrol engine was developed to overcome drudgery of threshing with manually operated thresher and also to replace motorized cowpea thresher that cannot be used in areas where there is no supply of electricity. The performance tests on the machine were replicated three times using 10000, 8000 and 6000 grams of kannanado cowpea pods at the threshing cylinder speed of 700, 800 and 900 rpm each and moisture contents of 11.05%, 13.65% and 14.75% respectively based on the following parameters; Threshing efficiency, throughput capacity and percentage seed damage. The findings of the tests showed that the thresher had highest threshing efficiency of 98% at moisture content of 11.05%, threshing cylinder speed of 900 rpm and feed rate of 6 kg/hr. The maximum throughput capacity was observed to be 46.18 kg/hr at the feed rate of 10 kg/hr, 11.05% grain moisture content and threshing cylinder speed of 900 rpm. A highest cleaning efficiency and grain damage of 93.06% and 4.90% respectively were observed. This revealed that as the cylinder speed increased the threshing and cleaning efficiency and the throughput capacity also increased whereas feed rate and moisture content were decreased. The test also showed that high moisture content has a tendency to reduce the mechanical seed damage for the variety (kannanado) of cowpea investigated. Therefore, cowpea moisture contents of 11.05 % and threshing cylinder speeds of 900 rpm are the crop-machine parameters combination for optimum thresher performance. The performance of the machine is satisfactory; small-scale farmers will find more comfort in using it for threshing.

Abstract
INTRODUCTION Subtotal cholecystectomy (STC) is an alternative to total cholecystectomy (TC) in patients with severe inflammation/adhesions around the hepatocystic triangle. This study aimed to evaluate the safety profile of STC. METHODS We retrospectively reviewed all patients who had STC at our unit between February 2009 and August 2019. STC was divided into two types, reconstituting (R-STC) and fenestrating (F-STC), depending on whether the gall bladder remnant was closed or left open. Patients who had cholecystectomy for gall bladder malignancy or as part of another operation were excluded from the study. RESULTS A total of 5,664 patients underwent cholecystectomy during the study period. Of these, 97 (1.7%) underwent STC. The laparoscopic to open conversion rate was high at 48.8% (47 cases), as was the overall postoperative complication rate (45.4%, 44 cases). No patient suffered iatrogenic bile duct injury. Nineteen patients (19.6%) suffered postoperative bile leak. This was significantly higher in patients who had STC in the acute setting (41% vs 13% for elective STC cases; p=0.04). There was no significant difference in rate of bile leak or other complications between R-STC and F-STC types. The 90-day readmission rate was 8.2% (8 cases). No mortalities were recorded within 90 days post STC. CONCLUSIONS STC seems to be an effective technique to avoid bile duct injury in difficult cholecystectomy cases. However, the perioperative morbidity associated with STC is relatively high. Surgeons should be aware of the risks of STC and take appropriate steps to minimise them.

Abstract
Erectile dysfunction (ED) has been identified as one of the most frequent chronic complications of diabetes mellitus (DM). The prevalence of ED is estimated to be about 67.4% in all DM cases worldwide. The pathophysiological process leading to ED involves endothelial, neurological, hormonal, and psychological factors. In DM, endothelial and neurological factors play a crucial role. Damages in the blood vessels and erectile tissue due to insulin resistance are the hallmark of ED in DM. The current treatments for ED include phosphodiesterase-5 inhibitors and penile prosthesis surgery. However, these treatments are limited in terms of just relieving the symptoms, but not resolving the cause of the problem. The use of stem cells for treating ED is currently being studied mostly in experimental animals. The stem cells used are derived from adipose tissue, bone, or human urine. Most of the studies observed an improvement in erectile quality in the experimental animals as well as an improvement in erectile tissue. However, research on stem cell therapy for ED in humans remains to be limited. Nevertheless, significant findings from studies using animal models indicate a potential use of stem cells in the treatment of ED.

Abstract
A novel nanomaterial, bacterial cellulose (BC), has become noteworthy recently due to its better physicochemical properties and biodegradability, which are desirable for various applications. Since cost is a significant limitation in the production of cellulose, current efforts are focused on the use of industrial waste as a cost-effective substrate for the synthesis of BC or microbial cellulose. The utilization of industrial wastes and byproduct streams as fermentation media could improve the cost-competitiveness of BC production. This paper examines the feasibility of using typical wastes generated by industry sectors as sources of nutrients (carbon and nitrogen) for the commercial-scale production of BC. Numerous preliminary findings in the literature data have revealed the potential to yield a high concentration of BC from various industrial wastes. These findings indicated the need to optimize culture conditions, aiming for improved large-scale production of BC from waste streams.

Abstract
INTRODUCTION Antibiotic resistance is a burgeoning problem worldwide. The trend of bacterial resistance has increased over the past decade in which more common bacteria are becoming resistant to almost all the antibiotics currently in use, posing a threat to humans and even livestock. METHODS The databases used to search for the relevant articles for this review include PubMed, Science Direct, and Scopus. The following keywords were used in the search: Antimicrobial resistance, Malaysian action plan, antibioticresistant bacteria, and Malaysian National Surveillance on Antimicrobial Resistance (NSAR). The relevant articles published in English were considered. RESULTS The antibiotic-resistant bacteria highlighted in this review showed an increase in resistance patterns to the majority of the antibiotics tested. The Malaysian government has come up with an action plan to create public awareness and to educate them regarding the health implications of antibiotic resistance. CONCLUSION Antimicrobial resistance in Malaysia continues to escalate and is attributed to the overuse and misuse of antibiotics in various fields. As this crisis impacts the health of both humans and animals, therefore a joined continuous effort from all sectors is warranted to reduce the spread and minimize its development.

Abstract
Abstract
Introduction
Recent research on the management of cholecystolithiasis with co-existing choledocholithiasis suggests performing cholecystectomy within 24 hours after ERCP has favourable outcomes. However, this target can be difficult to achieve in the NHS due to limited resources.
Method
This retrospective study includes 444 patients who underwent successful ERCP before cholecystectomy. We examined the impact of the duration of ERCP to cholecystectomy and post ERCP complications on operative difficulty and patient outcomes. We also report on gallstone related readmissions and rate of retained stones.
Results
The median duration from ERCP to cholecystectomy was 75 days, with a 14% readmission rate between their first successful ERCP and cholecystectomy.
Our analysis showed a statistically significant negative correlation between ERCP-to-cholecystectomy duration and postoperative stay. Readmissions increased with time, but this did not reach statistical significance. The occurrence of post ERCP complications significantly increased postoperative stay and the open conversion rate.
Conclusions
In contrast to recent research, our analysis suggests that early cholecystectomy post ERCP is not associated with better outcome. However, the impact of gallstone related readmissions needs further analysis. Post ERCP complication could serve as a predictor for operative difficulty and longer postoperative stay. It should be considered when planning the cholecystectomy.

Abstract
Background: Traditionally, stroke rehabilitation outcomes are based on indicators of physical function, such measures may underrate the all-inclusive impact of stroke such as oral health.Objectives: To investigate the relationship between upper extremity motor function and oral hygiene status as well as the impact of stroke on Oral Health-Related Quality of Life (OHRQoL).Methods: Sixty stroke survivors were included in this cross-sectional survey. Spasticity and motor function/mobility of the affected upper extremity were assessed using the Modified Ashworth Scale and Action Research Arm Test, respectively. Oral hygiene was assessed using the Simplified Oral Hygiene Index and oral health impact was assessed using the 14-item Oral Health Impact Profile. Pearson's moment correlation coefficient was used to determine the relationship between oral hygiene and upper extremity motor function variables.Results: There were significant relationships between the oral hygiene index and Shoulder muscles spasticity (r = 0.374, p = .01), wrist muscles spasticity (r = 0.352, p = .01), as well as basic mobility (r = 0.423, p = .01). An estimated 8% (n = 5) of study participants have their QoL strongly impacted by their oral health.Conclusions: Upper extremity motor function variables such as spasticity and basic mobility matters in determining oral hygiene status after stroke. Stroke has little impact on oral health-related quality of life.

Abstract
INTRODUCTION The susceptibility patterns of anaerobes are becoming less predictable due to the emergence of anaerobic resistance trends to antibiotics; hence increasing the importance of the isolation and antimicrobial susceptibility testing of anaerobes. MATERIALS AND METHODS This study investigated the isolation of anaerobes from the clinical specimens of Hospital Sungai Buloh, Malaysia, from January 2015 to December 2015. All isolates were identified using the API 20A system (bioMérieux, France). Antimicrobial susceptibility testing was performed using the E-test (bioMérieux, France). RESULTS The proportion of obligate anaerobes isolated from the clinical specimens was 0.83%. The Gram-positive anaerobes were most susceptible to vancomycin and imipenem, showing 100% sensitivity to these antimicrobials, followed by clindamycin (86.3%), penicillin (76.7%), and metronidazole (48.9%). Meanwhile, Gram-negative anaerobes were most susceptible to metronidazole (96%) followed by imipenem (89%), clindamycin (79%), and ampicillin (32%). The present study also showed that 3 out of 12 Bacteroides fragilis isolates were resistant to imipenem. CONCLUSION This study demonstrated the differences in the susceptibility patterns of anaerobes towards commonly used antimicrobials for the treatment of anaerobic infections. In summary, continuous monitoring of antimicrobial resistance trends among anaerobes is needed to ensure the appropriateness of treatment.

Abstract
Background:Osteoarthritis (OA) and rheumatoid arthritis (RA) are the most frequent inflammatory diseases of the musculoskeletal system, which could not be differentiated in their early stages, and characterized by degradation of articular cartilage and impairment of joint function. Sometimes, criteria and radiography are not insufficient to distinguish early-stages of RA and OA and predict disease course, and therefor biomarkers that help clinicians to early diagnose disease are essential.Objectives:The aim of this study is to estimate serum level of Matrix metalloproteinase 3 (MMP3) and hrdroxyproline (HP) in early RA and OA patients to see if they can be used to differentiate both diseases at their early stagesMethods:The aim of this study is to estimate serum level of Matrix metalloproteinase 3 (MMP3) and hrdroxyproline (HP) in early RA and OA patients to see if they can be used to differentiate both diseases at their early stagesResults:We found a highly significant elevation of serum MMP3 in OA patients group compared to RA patients and control groups. We also found a highly significant elevation of MMP3 in RA patients than control group,(P < 0.001). Meanwhile, we found a highly significant elevation of HP in OA patients than in RA patients and control groups, (P < 0.001), whereas there was no significant difference between HP in RA patients and control groups (P > 0.05).Table 1.Demonstration of serum levels of MMP3 and HP in all groups.“Enzyme”OA(n=40)RA(n=40)Control(n=40)p-valueMMP3 pg/mL559.92±1112.84153.25±162.0559.79±63.54<0.001HPµg/mL12.87±18.754.81±6.894.52±1.55<0.001HPµg/mL4.81±6.894.52±1.55> 0.05Conclusion:Our results suggest that serum levels of Hydroxyproline (HP) rather than MMP3 could be used as a potential biomarker for early differentiation between osteoarthritis (OA) and rheumatoid arthritis (RA) when diagnostic criteria failed to be fulfilled.References:[1]Benedetti S, Canino C, Tonti G, Medda V, Calcaterra P, Nappi G, Salaffi F, Canestrari F.

Abstract
Abstract
Introduction
Right ventricular (RV) size informs about prognosis and need for pulmonary valve replacement in patients with repaired tetralogy of Fallot (rTOF). Cardiac magnetic resonance (CMR) is considered the reference standard for measurement of RV volumes. Despite known limitations for RV evaluation, 2D transthoracic echocardiography (TTE) remains the primary and most available imaging modality in the rTOF population.
Purpose
To determine which TTE RV size parameters best correlate with CMR-derived indexed RV end-diastolic (RVEDVi) and end-systolic (RVESVi) volumes in the rTOF population. We sought to determine the best TTE measurement thresholds to predict normal RV volume (RVEDVi ≤110 mL/m2) and significant RV dilatation by CMR (RVEDVi ≥150ml/m2).
Method
We retrospectively enrolled all rTOF patients followed at a single-center between 2010 and 2018 who had both TTE and CMR exams performed within a 12-month interval. All TTE exams were reviewed by an observer measuring RV areas, RV inlet and RV outlet at end-diastole and end-systole. Analyses of CMR studies were performed by 3 observers who measured RV area, RV inlet, RV outlet and RV volumes at end-diastole and end-systole. Correlations between TTE and CMR parameters were performed using Pearson correlation coefficients. Using the TTE RV parameters with the strongest correlation with CMR, we subsequently determined thresholds to predict a CMR RVEDVi ≤110ml/m2 and ≥150ml/m2 using ROC analysis.
Results
We enrolled 130 patients (59 women [45%], mean age 43±12.8 years). Median age at TOF repair was 4 [3–6] years; 18 patients (14%) had subsequent pulmonary valve replacement. Median interval between TTE and CMR exams was 114 [59–239] days. There were significant correlations between all TTE parameters and CMR RVEDVi. TTE indexed RV end-diastolic area (RVEDAi) most strongly correlated with CMR RVEDVi (r=0.73, p<0.0001). All TTE RV parameters significantly correlated with CMR RVESVi but indexed RV end-systolic area had the strongest correlation (r=0.77, p<0.0001). ROC analysis performed to predict RVEDVi of ≤110ml/m2 and ≥150ml/m2 using TTE RVEDAi revealed areas under the curve of 0.86±0.04 and 0.90±0.03, respectively. A TTE RVEDAi ≤17cm2/m2 predicted a normal CMR RV volume (≤110ml/m2) with a sensitivity of 90% and a specificity of 74%. A TTE RVEDAi ≥19cm2/m2 predicted a CMR RVEDVi ≥150 mL/m2 with a sensitivity of 93% and a specificity of 76%.
Conclusion
In rTOF patients, both diastolic and systolic TTE RV area best correlate with CMR-derived RV end-diastolic and end-systolic volumes. A cut-off value of TTE RVEDAi of 19cm2/m2 is 93% sensitive and 76% specific to predict a CMR RVEDVi ≥150ml/m2. Simple RV size measurement using TTE may help inform the need and frequency of CMR evaluations in rTOF patients.

Abstract
In the current study, tyrosine aminotransferase (TAT) as a target enzyme was purified from the liver of control and Schistosoma-infected mice that was subjected to catalytic investigation. The purified enzyme has a single band on SDS-PAGE with a molecular mass of almost 100 KD from control and infected mice. The kinetic studies of hepatic TAT towards its substrates showed no change in Km, whereas Vmax value was increased from 2.3 to 2.9 fold in the enzyme isolated from Schistsoma- infected mice. In addition, the Kcat/ Km ratio displayed a higher value for the enzyme from infected mice, indicating that it is more efficient and specific. On the other hand, the in vitro effect of praziquantel showed a slight activation of hepatic TAT in both control and infected mice, whereas mirazid (MZD) has an inhibitory effect in a concentration-dependent manner. The response of TAT from infected mice towards MZD inhibition is less than that from controls. These data suggest that there is a change in the catalytic properties of hepatic TAT in schistosomiasis and the in vitro effect of the schistosomicidal drugs appears to have inductive or inhibitory effect.

Abstract
BACKGROUND Although there is a recommendation that toddlers be screened for Autism spectrum disorder (ASD) during their 18- and 24-month well-care child visits, diagnosis often occurs well after the child turns 4 years old. Such delayed diagnosis hinders the implementation of early intervention thus worsens the long-term prognosis of ASD. OBJECTIVE The current community-based study in its stage I aimed at early screening of Egyptian toddlers for ASD using an Arabic validated version of Modified Checklist for Autism in Toddlers (M-CHAT). METHODOLOGY A cross-sectional community-based descriptive study was carried out enrolling 5546 Egyptian toddlers. They were randomly recruited from those attending Primary Health Care Units in six Egyptian governorates with a fair representation of the urban, semi-urban, and rural Egyptian populations. An Arabic validated version of M-CHAT was used as a screening tool for ASD. RESULTS The current study revealed failure of M-CHAT (suspected to have ASD and needs further evaluation) in 1320 out of the enrolled 5546 Egyptian toddlers (23.8%). CONCLUSION M-CHAT as a screening tool for ASD has flagged a considerable percent of the enrolled toddlers that necessitates referral for further evaluation (stage II) to settle the diagnosis of ASD in the true positive cases. Perfecting the delicate balance between sensitivity and specificity for ASD screening tools is crucial in order not to miss early detection of ASD cases and at the same time, to avoid over-diagnosis with subsequent abuse of the limited healthcare resources in developing countries.

Abstract
Highly pathogenic avian influenza A (HPAI) H5N1 viruses continue to be a major veterinary and public health problem in Egypt. Continued surveillance of these viruses is necessary to devise strategies to control the spread of the virus and to monitor its evolutionary patterns. This is a report of the identification of a variant strain of HPAI H5N1 virus during an outbreak in 2010 in vaccinated chicken flocks in a poultry farm in Assiut, Egypt. Vaccination of chickens with an oil-emulsified inactivated A/chicken/Mexico/232/94 (H5N2) vaccine induced high levels of hemagglutination inhibition (HI) antibody titers reaching up to 9 log2. However, all flocks irrespective of the number of vaccine doses and the resultant HI titer levels came down with severe influenza infections. The qRT-PCR and rapid antigen test confirmed the influenza virus to be from H5N1 subtype. Sequencing of the hemagglutinin (HA) gene fragment from ten independent samples demonstrated that a single H5N1 strain was involved. This strain belonged to clade 2.2.1 and had several mutations in the receptor-binding site of the HA protein, thereby producing a variant strain of HPAI H5N1 virus which was antigenically different from the parent clade 2.2.1 virus circulating in Egypt at that time. In order to define the variability in HPAI H5N1 viruses over time in Egypt, we sequenced another H5N1 virus that was causing infections in chickens in 2014. Phylogenetic analysis revealed that both viruses had further distanced from the parent virus circulating during 2010. This study highlights that the antigenic mutations in HPAI H5N1 viruses represent a definitive challenge for the development of an effective vaccine for poultry. Overall, the results emphasize the need for continued surveillance of H5N1 outbreaks and extensive characterization of virus isolates from vaccinated and non-vaccinated poultry populations to better understand genetic changes and their implications.
