Periodontitis Patients’ Oral Health Experience and Quality of Life during the Malaysian Movement Control Order-2020 (Pengalaman Kesihatan Pergigian dan Kualiti Hidup Pesakit Periodontitis semasa Perintah Kawalan Pergerakan Malaysia-2020) / Jurnal Sains Kesihatan Malaysia

@#The coronavirus disease 2019 (COVID-19) has sparked concerns among dental patients due to its high infectivity. The implementation of the Movement Control Order in 2020 by the Malaysian government (MMCO-2020) has added constraints to access to dental clinics and may affect the patients’ status of oral disease. This study aims to investigate the impact of MMCO-2020 on the periodontal health and oral health-related quality of life (OHRQoL) of periodontitis patients with/out non-communicable diseases (NCDs). A cross-sectional study involving 139 patients with periodontitis was conducted to assess patients’ OHRQoL, oral health problems, and their perceived barriers to access dental treatment during MMCO-2020 using the Oral Health Impact Profile (OHIP-14) and questionnaire on oral health-related problems. The overall mean OHIP-14 score was relatively low (10.08 ± 8.861), suggesting that the OHRQoL is generally good during MMCO-2020. However, 44 (31.7%) periodontitis patients score ADD ≥14, indicating poorer oral health status and greater dental treatment needed. There was statistically significant association between periodontitis patients with comorbidities (i.e., presence of NCDs) with poorer OHIP-14 scores and mean plaque score changes at pre- and postMMCO, suggesting that special care is required by this group, even during the national lockdown. Of the 45 (32.4%) patients who reported having problems, most (30, 36.1%) decided to “visit the dentist for treatment’. Meanwhile, the most frequent barriers were “could not get an appointment” (14, 34%), “problem is not serious” (13, 39.4%) and “fear of COVID” (9, 27.3%). The MMCO-2020 restrictions on the population had a minimal negative impact on the OHRQoL of patients with periodontal disease, but provisions can be arranged to address the basic and urgent needs of selected periodontitis patients, especially those presented with medical comorbidities.

Omega 3 fatty acids - Potential modulators for oxidative stress and inflammation in the management of sickle cell disease

Abstract Objective Sickle cell disease is characterized by clinical complications resulting in vaso-occlusive crisis with prominent attributes of oxidative stress, inflammation, and pain. Inflammation is an integral part of this disease which further exacerbates the pain during a crisis. Omega-3 fatty acids are known to possess anti-inflammatory and anti-aggregatory properties and assist in diminishing the slow physiological inactivation. Methods A pilot nutritional interventional study was conducted wherein forty-three children with sickle cell disease aged 5-16 years were supplemented with omega-3 fatty acids for a period of six months. Analysis of oxidative stress, as well as inflammatory parameters, was done pre and post-supplementation. Results Increased free oxygen radical transference values depicting free radical generation is enhanced in these patients along with a reduced antioxidant defense, as seen by decreased free oxygen radical defense values. Supplementation with omega-3 fatty acids for a period of six months significantly reduced the inflammatory marker homocysteine in all patients, whereas high sensitive C reactive protein was significantly reduced only in females of the age group 11-16years. Simultaneously a significant reduction in oxidative stress parameters with a concomitant increase of antioxidant defense was observed in all patients. Conclusion The authors' findings suggest the regulatory effects of omega-3 fatty acids as cellular activators in alleviating the complications due to sickle cell disease. Omega-3 fatty acids hold promise as future therapeutic candidates in patients with sickle cell disease.

Extensive Giant Lipoma of Oropharynx

@#Lipoma is a benign, slow growing tumour composed of adipose tissue. In general, it is very unusual for lipoma to form in the head and neck region, let alone achieve a size of more than 10 cm with the involvement of deep neck spaces. We discussed a case of an extremely huge neck lipoma measuring 18 cm x 14 cm with extensive involvement of deep neck spaces, infratemporal fossa and pharynx, closely adherent to submandibular and parotid gland. The diagnostic and therapeutic challenges were discussed, in achieving a surgically complete excision and cosmetically acceptable outcome

A Scoping Review on Salt Reduction Intervention

@#Excessive salt intake has been linked to the development of hypertension and non-communicable diseases. This study aims to explore the different types of salt reduction intervention implemented among adults aged ≥18 years and to identify the suitable settings, duration and tools used for effective salt reduction interventions. This review adapted the established structured scoping review framework by Arksey and O’Malley. Related articles from the year 2008 to 2018 were retrieved based on the study objectives using keywords in electronic databases and through a bibliographic search of books, reports, conference proceedings, posters and summaries. Out of 130 potentially relevant full-text articles assessed, 14 articles were included in the review. Suitable salt reduction initiatives for the community who regularly consume home-cooked food are through cooking and usage of a tool such as a salt-restriction spoon, together with awareness on the benefits of salt reduction in their daily diet. Healthy catering initiative should be implemented in the workplace or institution-based settings. Policy development targeting the source of salts such as mandatory usage of salt-substitutes or Front-of-Pack labelling of salt content in all food products suitable for population-level intervention.

Associations of Gender and BMI-for-age Status (BAZ) With Nutrient Intake Among Adolescents in Malaysia: Findings From Adolescent Nutrition Survey (ANS) 2017

@#Introduction: Adolescence is an important growth period for individuals. High prevalence of obesity among adolescents in Malaysia in recent years is worrying. This study aims to assess associations of gender and BMI-for-age status (BAZ) with nutrient intake of adolescents between 13-17 years old in Malaysia. Methods: Data of 999 respondents were drawn from Adolescent Nutrition Survey 2017; a cross-sectional school-based survey involving adolescents aged 10 to 17 years old. Respondents were selected using multistage stratified cluster sampling from 13 states and three federal territories in Malaysia to ensure nationally representative data. Data collection was undertaken from March until May 2017. Dietary intake was assessed using a single 24-hours dietary recall conducted via face-to-face interview by trained nutritionists. Nutritionist ProTM Diet Analysis Software was used to calculate nutritional intake values. Anthropometric measurements were measured using validated equipment. Nutritional status of the respondents was assessed using BMI-for-Age z-score and categorised based on WHO Growth Reference 2007. Results: The mean energy intake of the adolescents was 1972 kcal/day. Majority of the adolescents had normal BMI (74.6%) while overweight, obese and thinness were 12.0%, 7.2% and 6.2% respectively. Boys had significantly higher intakes of energy, carbohydrate, protein, fat, sugar, cholesterol, thiamin, Vitamin A, calcium, iron, sodium and potassium compared to the girls. Obese adolescents had significantly higher energy, carbohydrate, fat, sugar, Vitamin A and calcium intakes compared to other BMI groups. Conclusion: The findings highlighted the need for cultivating self-awareness on healthy eating among adolescents.

Glutathione (GSH) improves sperm quality and testicular morphology in streptozotocin-induced diabetic mice / 亚洲男科学杂志(英文版)

Diabetes mellitus (DM) is known to cause reproductive impairment. In men, it has been linked to altered sperm quality and testicular damage. Oxidative stress (OS) plays a pivotal role in the development of DM complications. Glutathione (GSH) is a part of a nonenzymatic antioxidant defense system that protects lipid, protein, and nucleic acids from oxidative damage. However, the protective effects of exogenous GSH on the male reproductive system have not been comprehensively examined. This study determined the impact of GSH supplementation in ameliorating the adverse effect of type 1 DM on sperm quality and the seminiferous tubules of diabetic C57BL/6NTac mice. GSH at the doses of 15 mg kg

Calcium and iron intakes of adolescents in Malaysia and their relationships with body mass index (BMI): Findings from the Adolescent Nutrition Survey 2017

@#Introduction: Adolescent health is a priority considering they represent the future generation. Data from the Adolescent Nutrition Survey 2017 were analysed to determine the prevalence of micronutrient inadequacy, particularly calcium and iron, and the relationship with body mass index (BMI) among Malaysian secondary school students. Methods: This cross-sectional study included students aged 13 to 17 years old studying at public and private schools. Twenty-four hours dietary recall via face-to-face interview was conducted by trained nutritionists to obtain data on dietary intake. For nutritional status, BMI-for-age z-score (BAZ) was analysed using WHO Anthroplus software. Results: From 999 respondents, 449 were boys and 550 were girls. Overall findings indicated that both boys and girls had inadequate intakes of calcium and iron in their daily diet. Mean intakes of calcium (695.7±463.2 mg/day) and iron (23.4±21.0 mg/day) were higher among boys aged 16 to 17 years old. Mean intake of iron were higher among the older age groups. Majority of the respondents (boys: 94%; girls: 97%) did not meet the recommended nutrient intake (RNI) for calcium and more than half (boys: 50%; girl: 80%) did not achieve the RNI for iron. Current findings also found significant positive but weak correlations between calcium (r=0.112, p=0.001) and iron (r=0.084, p=0.008) intakes with BMI-for-age. Conclusion: BMI-for-age was related to calcium and iron intakes among secondary school students in Malaysia. Thus, intervention strategies should focus on early screening and nutrition education on food choices of high calcium and high iron contents, including iron supplementation programmes, if needed.

Factors associated with sugar-sweetened beverages consumption among Malaysian adolescents: findings from the Adolescent Nutrition Survey 2017

@#Introduction: Childhood obesity is a public health problem in Malaysia. Intake of sugar-sweetened beverages (SSB) is associated with obesity in children. There is a lack of studies on factors associated with SSB consumption in Malaysia. This study aimed to determine the sociodemographic factors associated with SSB consumption among Malaysian adolescents. Methods: Data of 2,021 students, aged 10-17 years on sociodemographic, SSB intake and anthropometrics were drawn from the school-based Adolescent Nutrition Survey 2017. A multistage stratified cluster sampling was used to obtain a nationally representative sample of primary and secondary school students. Body mass index (BMI)-for-age status was determined based on calculated z-score using the World Health Organization 2007 reference. SSB consumption was obtained from a food frequency questionnaire. Results: The prevalence of overweight and obesity among Malaysian adolescents were 16.6% and 14.7%, respectively. Malaysian adolescents consumed 1.4 cups of SSB per day. Rural children had a significantly higher SSB intake (1.5 cups) than urban (1.3 cups) children, while males (1.5 cups) had a significantly higher intake than females (1.3 cups). There were no significant differences in SSB consumption between thin, normal, overweight and obese adolescents. Conclusion: Almost all Malaysian adolescents consumed SSB during one month prior to the survey and the average amount consumed was 1.4 cups per day. Rural locality and male were associated with higher SSB consumption. There were differences in SSB consumption between Chinese and Malays, between Chinese and Indians, and between Chinese and Bumiputra Sarawak. There were no differences in consumption between the different BMI-for-age categories.

Gastrointestinal symptoms in COVID-19 patients: a case series

The coronavirus disease 2019 (COVID-19) pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), presents an ongoing global threat. Common clinical features reported in early confirmed infections included fever, cough, and myalgias or fatigue. But as testing capacity and case numbers have increased worldwide, gastrointestinal (GI) symptoms such as diarrhoea, nausea/vomiting, abdominal pain, and loss of appetite have been increasingly recognized. Authors present a case series of gastrointestinal symptoms in COVID-19 patients and how they were managed at the hospital. However, correlations between the presence of fecal virus RNA and severity of digestive symptoms, namely, diarrhoea severity could not be established due to unavailability of the test in the hospital setting. Although knowledge about the viability of SARS-CoV-2 is limited, the virus could remain viable in the environment for days, which could lead to faeco-oral transmission. Various studies conducted on COVID-19 patients recommended routine stool sample testing with real-time RT-PCR after the clearance of viral RNA in a patient’s respiratory samples. Strict precautions to prevent transmission should be taken for patients who are in hospital or self-quarantined if their faecal samples test positive. Optimally, testing for COVID-19 should be performed using both respiratory and stool samples, if available.

Comparison of pelvic floor dysfunction in primiparous and nulliparous women and its relation to pelvic floor muscle strength

Background: The pelvic floor muscles (PFM) play an important role in supporting the pelvic and abdominal organs and controlling urinary and fecal continence, in addition to their role in the sexual function. The objective of this study was to compare pelvic floor muscle strength in primiparous 6 months after delivery and nulliparous women, to evaluate pelvic floor dysfunction (PFD) in these women and to find the association of PFD with pelvic floor muscle strength (PFMS).Methods: A total of 100 women were recruited in the cross-sectional study which included 28 nulliparous and 72 primiparous women 6 months after delivery. The assessment included general physical examination (GPE), POP-Q and assessment of pelvic floor muscle strength by modified oxford score and perineometer.Results: Endurance of PFMS measured by duration of contraction and number of contractions/min was higher in nulliparous. Mean of the duration of contraction was significantly higher in nulliparous group as compared to primipara i.e., 28.61 seconds and 23.9 seconds in nulliparous and primiparous group respectively (p=0.005). Mean of the number of contractions performed in one minute was significantly higher in nulliparous group as compared to primipara i.e., 31.04 and 19.97 in nulliparous and primiparous group respectively (p<0.0001). None of the nulliparous women had any PFD symptoms, while 4.17% of the primiparous patients had PFD in the form of bladder symptoms and 1.39% of them had PFD in the form bowel symptoms. Vaginal squeeze pressure was found to be affected by mode of delivery. It was lowest in instrumental delivery. It was 39.78±13.33 cmH20 in vaginal delivery, 51.42±12.88 cmH2O in Caesarean section and 31.67±14.36 cmH2O in instrumental delivery (p-0.039).Conclusions: Endurance of PFMS measured by duration of contraction and number of contractions/min was higher in nulliparous. Vaginal squeeze pressure was found to be affected by mode of delivery. It was lowest in instrumental delivery.

Investigation Of Ergonomic Risk Factors Among Male Workers In A Medical Manufacturing Company In Northern Malaysia

@#The medical manufacturing industry is currently one of the sectors with great potential growth in Malaysia, which offers numerous job opportunities to local and foreign workers. The growing proportion of workers in this industry means that a large number of workers are potentially exposed to ergonomic risk factors at the workplace, which may consequently affect their health. Thus, this study was carried out is to investigate the ergonomic risk factors and the prevalence of musculoskeletal disorders among male workers in a medical manufacturing company in northern Malaysia. Eight industrial workers (n = 8) were recruited from two Plastic Technology (PT) departments to participate in this study. Observations were made by recording the participants performing two tasks (manual lifting of containers and bags of chemicals) using a video camera at the PT1 and PT3 departments. The participants’ personal information and their job-related characteristics were first collected using a demographic questionnaire. Next, the Cornell Musculoskeletal and Hand Discomfort Questionnaire (CMDQ) was used to evaluate the prevalence of musculoskeletal disorders among workers while Manual Handling Assessment Charts (MAC) were used to assess the most common risk factors during the lifting operations. The results showed that the highest prevalence of musculoskeletal disorders among the male workers at the medical manufacturing company was at the lower back (83.17%), upper back (4.38%), right shoulder (3.49%), and left shoulder (3.49%). Based on the results of the MAC, 100% of the participants were at high risk of injury from postures in the vertical lift zones, torso twisting, and sideways bending. In addition, 87.5 and 62.5% of the participants were at high risk of injury based on their hand distance from the lower back and grip on the load, respectively. The results of this study can serve as a guideline to implement interventional ergonomics programmes at the workplace and improve the musculoskeletal health of workers in the medical manufacturing industry in Malaysia.

Oral Health Knowledge among Healthcare Professionals and Their Challenges in Dealing with Patients’ Oral Health Problems (Pengetahuan Kesihatan Pergigian di Kalangan Pengamal Penjagaan Kesihatan Profesional dan Cabaran dalam Mengendalikan Masalah Pergigian Pesakit) / Jurnal Sains Kesihatan Malaysia

@#The important role of non-dental healthcare professionals (HCPs) in promoting oral health is well-accepted and has received increased attention in recent years. However, greater efforts are needed to train them in ensuring better competency in delivering this role. The aim of the present study is to assess oral health and care knowledge among HCPs by further exploring possible challenges faced by them in managing oral health problems, particularly in regard to patients in a public primary healthcare clinic. In the case of the current research, a focus group discussion was carried out with ten HCPs who are directly involved with patients from different units within the health clinics. In particular, the questions developed for the focus group discussion were divided into two parts: (1) knowledge on oral health and its link to general health, and (2) issues and challenges faced by HCPs in handling patients with oral health problems in their daily routine. The session was recorded on a digital audio tape, the responses were then transcribed, followed by the grouping of the scripts which were then qualitatively analysed. The results revealed that majority of the participants appeared to have good knowledge of general and basic oral health; however, only very few of them were aware of the relationship between oral health problems with systemic conditions. Meanwhile, one of the main challenges faced by HCPs in handling patients with oral health problems is their limited knowledge of oral health problems. Specifically, the main challenges refer to the management of medically compromised patient requiring dental treatment as well as the difficulty in changing the mindset of patients regarding oral health issues, especially in terms of seeking dental treatment. In conclusion, it has been clearly observed that HCPs involved in the present study have good knowledge of general health and oral health but limited knowledge related to oral health to systemic health. Furthermore, they tend to face numerous challenges when dealing with patients, especially due to their limited knowledge of oral health facts and drug prescription for oral problems. Therefore, there is an urgent need of additional training for both HCPs and dental teams for the purpose of enabling both parties to provide coordinated and comprehensive service to patients with oral health problems at the primary healthcare clinics.

Epidemiology and risk factors of transfusion transmitted infections in thalassemia major: a multicenter study in Pakistan

ABSTRACT Background: Blood transfusion-transmitted infections in individuals suffering from beta-thalassemia have been reported in Pakistan, but the information on their sociodemographic and clinical determinants is lacking. This study aims to describe the prevalence, as well as the factors, contributing in blood transfusion-transmitted infections. Method: Between December 2011 and December 2013, in a non-probable sampling, 350 thalassemia patients were recruited in Lahore, Multan, Karachi and Peshawar, Pakistan. Subjects were screened for transfusion-transmitted infections. Results: A seropositive rate of 36.5% was observed; males (94, 73.4%) and females (34, 26.6%). Among several risk factors associated with transfusion-transmitted infections, province (p = 0.001), gender (p = 0.003), age (p < 0.03), education (p < 0.00), degree of consanguinity (p = 0.05), age at fetal blood test (p = 0.005), fetal hemoglobin levels (p = 0.005), death due to thalassemia (p = 0.001) and iron-related complications (p = 0.04) showed significant correlation. Participants with an age >10 years were significantly more prone to seropositivity than those aged ≤10 years. Moreover, the ferritin level was also significantly higher in those aged >10 years than in those ≤10 years. It was observed that males had a higher seroprevalence rate (94, 73.4%) than females (34, 26.6%). The most prevalent transfusion-transmitted infections was the hepatitis C virus, with 115 cases (89.8%). Conclusion: A high prevalence rate of HCV in subjects with transfusion-dependent thalassemia is linked with insufficient facilities, poor management and compromised socioeconomic status. Therefore, more multicenter studies covering cities from different regions of the country are needed in order to develop preventive measurements at the regional and national level.

FANCA Gene in Pakistani Fanconi Anemia Patients: Screening of Mutations in Exon 28 and Exon 29

Objective: This kind of study was conducted first time in Pakistan. Its objective was to ascertain the associated clinical features and analyze the FANCA exon 28 and exon 29 mutations in Pakistani Fanconi anemia (FA) patients. Methods: A total of 38 patients with Fanconi anemia were recruited presenting in the Armed forces institute of pathology (AFIP) Rawalpindi Pakistan. They were enrolled in this study on the basis of comprehensive clinical evaluation and positive Diepoxybutane (DEB)/Mitomycin C Chromosomal breakage test. Genomic DNA was extracted from peripheral blood of patients and age and gender-matched controls. Mutation analysis of FANCA gene was done by conventional Polymerase chain reaction (PCR) and DNA sequencing. Various online tools and software were used for analysis of the obtained data and identification of the sequence alterations in FANCA gene in exon 28 and exon 29 of FA patients. Results and Discussion: The current study on screening of FANCA mutational analysis in exon 28 and exon 29 revealed four novel mutations. These include three missense variants (p.F876L, p.L883H, and p.K921I) in exon 28 and a novel homozygous frameshift variant (p.S947FfsX950) in exon 29. In addition two new intronic variants were also found in this set of patients. Conclusion: The sequence variants identified in this study in 10 (26.31%) FA patients in two out of forty-three FANCA gene exons (i.e., exon 28 and exon 29) strongly emphasize the importance of large-scale molecular studies on FANCA gene in Pakistani population.

A study on correlation of placenta praevia with previous caesarean section and other risk factors

Background: Obstetric haemorrhage is the leading cause of preventable maternal mortality worldwide. One of the major contributors to obstetric haemorrhage is antepartum haemorrhage which is mainly caused by placenta praevia and abruptio placenta. The study aims to quantify the risk of placenta praevia based on the presence and number of caesarean sections and to assess other risk factors.Methods: This study was a prospective case control study conducted in the department of obstetrics and gynecology, Lalla Ded hospital, Srinagar, Jammu and Kashmir, India from August 2009 to October 2010. As per the inclusion and exclusion criteria of study 100 cases and 200 controls were selected and the association of placenta praevia with proposed risk factors was analysed statistically.Results: Present study showed that the risk of developing placenta praevia in future pregnancy increased steadily as the number of previous caesarean sections increased, risk being 2.1, 2.8 and 4 times with previous one, two and three caesarean deliveries respectively. Similarly, the risk of developing placenta praevia was more in women with history of previous abortion (risk being 2.8 and 6.5 times more in women with one and two abortions in the past). Previous dilatation and curettage and age more than 30 years also proved to be independent risk factors.Conclusions: To conclude advanced maternal age, previous abortion, dilatation and curettage and a history of previous caesarean section appear to increase the occurrence of placenta praevia. The study strongly emphasises the need to decrease the primary caesarean section rate.

Development of Smart Fruit Basket for Pineapple Harvesting

Abstract@#Introduction: Pineapple harvesting work contributes to the reporting of musculoskeletal symptoms (MSS) and ergonomic risks. Pineapples are harvested manually in some parts of Malaysia using rattan baskets and workers are exposed to excessive bending, pain and discomfort. This intervention study developed and tested a prototype of an ergonomic harvesting basket to potentially reduce discomfort and physiological workload during a simulation of harvesting activity. Methods: The development and testing of improved harvesting basket was performed in laboratory and workshop. The improved basket had adjustable cushion straps, foam back pad and an opening for unloading of fruits. Harvesting was simulated using improved and existing basket by human subjects and questionnaires were used to assess discomfort. Physiological workload was assessed by heart rate and energy expenditure. Results: A total of 12 male respondents with average age of 22.4 (2.2) years participated in harvesting simulation. Discomfort as measured in Likert scale (mean (standard deviation) for improved basket 4.13 (6.1) vs existing basket 12.26 (11.2); p<0.05) was significantly reduced. Average heart rate (94.13 beats/min vs 89.05 beats/min) and energy expenditure (6 kJ/min vs 5 kJ/min) improved. Conclusion: The use of improved basket was linked to reduction of discomfort and overall workload. Improving design of agricultural manual tools may be able to improve health of workers and prevent MSS. Future fabrication of the improved basket using lightweight materials has potential to be expanded into plantation sectors not limited to pineapples in Malaysia and across Asia.

Dengue seroprevalence and its socioeconomic determinants in Faisalabad, Pakistan: a cross-sectional study

Abstract INTRODUCTION: Socioeconomic disparities in the community make some groups more vulnerable to dengue infection. METHODS: Fourteen dengue cases (IgM positive) served as index cases for the positive geographic cluster investigations. RESULTS: Of 292 individuals, the overall dengue seroprevalence was 22.9% (IgM positive 4.8%; IgG positive 18.1%). The highest (45%) seroprevalence was reported in the most socioeconomically vulnerable lower class, followed by the middle class (39%). Orthogonal comparisons showed that socioeconomic factors play a significant role in the prevalence of dengue. CONCLUSIONS: An integrated approach is required to control the menace through vector control strategies and improvement of socioeconomic conditions.

Pseudomonas aeruginosa: evaluation of pathogen burden and drug-resistance trends in a tertiary care hospital

Objective: To evaluate the pathogen burden and antibiotic-resistance trends of Pseudomonas aeruginosa among hospitalised patients at a tertiary care hospital. Study Design: Retrospective, hospital record-based, cross-sectional study. Place and Duration of Study: Microbiology Laboratory, Allama Iqbal Medical College/Jinnah Hospital, Lahore, from January 2014 to December 2016

Methodology: A total of 5,960 samples were collected from clinically suspected cases of bacterial infections, admitted to the hospital. Microbial identification and antibiotic susceptibility pattern were carried out and analysed

Results: Out of a total of 5,960 samples, Pseudomonas aeruginosa was isolated from 1,268 [21.2%] specimens. Department-wise isolation rate was n=600 [42.9%], n=268 [15.4%], n=201 [12.6%], and n=199 [16.0%] from intensive care unit [ICU], surgical units, medical units, and Gynae wards, respectively [p<0.0001]. Sample-wise isolation rate was, wound swabs n=448 [35%], urine n=356 [28%], sputum n=187 [14 %], tracheal aspirate n=127 [10%], blood n=99 [7%], and broncho-alveolar lavage n=51 [4%] [p<0.0001]. Drug-resistance pattern showed low rates for carbapenems [meropenem n=440 [35%], Imipenem n=436 [34%] and beta-lactam + beta-lactamase inhibitor combination [piperacillin+ tazobactam n=437 [34%] while alarming rates were observed for cephalosporins [ceftazidime n=716 [56%], fluoroquinolones [ciprofloxacin n=690 [54%], cefoperazone+sulbactam n=685 [54%], aminoglycosides [gentamicin, n=669 [53%], amikacin n=608 [48%], and monobactams [aztreonam n=666 [52%]. Decreasing trend was observed only for amikacin 63% to 37%, aztreonam showed similar pattern throughout, while there was an increasing trend of drug resistance in all groups of antibiotics

Conclusion: Emerging drug-resistant strains of Pseudomonas aeruginosa are probably linked to the injudicious use of antibiotics, leading to ineffective empirical therapy. Therefore, we suggest that culture and antimicrobial susceptibility testing should be done for targeted antimicrobial therapy against Pseudomonas aeruginosa

Results: Out of total 3,951 samples, sputum was most freqently found pulmonary sample 48.4% [n=1915], extrapulmonary samples, pleural fluid and pus samples were most commonly observed samples 12.0% [n=476] and 8.3% [n=329], respectively. Overall false negativity was 23.1% [pulmonary=19.6%, extra-pulmonary=29.2%] [p<0.001], Maximum false negative results were observed in pericardial, synovial, pleural fluids, and pus samples as 40.0%, 38.0%, 33.0% and 32.0%, respectively

Conclusion: ZN smear microscopy is not a very efficient tool in case of patients with the low mycobacterial load. Therefore, National TB Control programs should consider extending their diagnostic approaches from ZN microscopy to more advanced techniques
