- Abstract
This study aimed to assess the impact of establishing a pre-hospital definitive airway on mortality and morbidity compared with no prehospital airway in cases of severe traumatic brain injury (TBI). Traumatic brain injury (TBI) is a global health concern that is associated with substantial morbidity and mortality. Prehospital intubation (PHI) has been proposed as a potential life-saving intervention for patients with severe TBI to mitigate secondary insults, such as hypoxemia and hypercapnia. However, their impact on patient outcomes remains controversial. A systematic review and meta-analysis were conducted to assess the effects of prehospital intubation versus no prehospital intubation on morbidity and mortality in patients with severe TBI, adhering to the PRISMA guidelines. 24 studies, comprising 56,543 patients, indicated no significant difference in mortality between pre-hospital and In-hospital Intubation (OR 0.89, 95% CI 0.65–1.23, p = 0.48), although substantial heterogeneity was noted. Morbidity analysis also showed no significant difference (OR 0.83, 95% CI 0.43–1.63, p = 0.59). These findings underscore the need for cautious interpretation due to heterogeneity and the influence of specific studies on the results. In summary, an initial assessment did not reveal any apparent disparity in mortality rates between individuals who received prehospital intubation and those who did not. However, subsequent analyses and randomized controlled trials (RCTs) demonstrated that patients who underwent prehospital intubation had a reduced risk of death and morbidity. The dependence on biased observational studies and the need for further replicated RCTs to validate these findings are evident. Despite the intricacy of the matter, it is crucial to intervene during severe airway impairment. [ABSTRACT FROM AUTHOR]

- Abstract
The choice of fluid resuscitation in Traumatic Hemorrhagic shock (THS) remains a critical aspect of patient management. Bicarbonated Ringers solution (BRS) has shown promise due to its composition resembling human Extracellular Fluid and its potential benefits on hemodynamics. To evaluate the efficacy, mortality rates, hemodynamic effects, and adverse outcomes of Sodium Bicarbonate Ringer's Solution in the treatment of hemorrhagic shock, as compared to other relevant interventions. A comprehensive examination of the available literature was performed by conducting systematic searches in prominent databases such as Cochrane, EMBASE, MEDLINE, and PubMed. The process employed predefined criteria to extract relevant data and evaluate the quality of the studies. The outcome measures considered encompassed survival rates, mortality, mean arterial pressure (MAP), heart rate (HR), and adverse events. The meta-analysis of three studies showed that compared to the other crystalloids, the use of BRS had an odds ratio for survival of 1.86 (95% CI: 0.94, 3.71; p = 0.08; I
2 = 0%), an odds ratio for total adverse events of 0.14 (95% CI: 0.06, 0.35; p < 0.0001; I2 = 22%), a mean difference in heart rate of −4.49 (95% CI: −7.55, −1.44; p = 0.004; I2 = 13%), and a mean difference in mean arterial pressure of 2.31 (95% CI: −0.85, 5.47; p = 0.15; I2 = 66%). BRS demonstrated a significant reduction in complications, including adult respiratory distress syndrome (ARDS), Multiple Organ Dysfunction (MODS), and Total Adverse Effects, when compared to other solutions in the treatment of THS. Additionally, THS patients resuscitated with BRS experienced a notable decrease in heart rate. The findings suggest BRS may contribute to organ stability and potential survival improvement due to its similarity to human Extracellular Fluid and minimal impact on the liver.

- Abstract
Antibiotics are gradually becoming less effective against bacteria worldwide, and this issue is of particular concern in economically-developing nations like Pakistan. We undertook a scoping review in order to review the literature on antimicrobial use, prescribing, dispensing and the challenges associated with antimicrobial resistance in primary care (PC) settings in Pakistan. Furthermore, this review aims to identify potential solutions to promote appropriate use of antimicrobials in Pakistan. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews (PRISMA-ScR) checklist, a comprehensive scoping review was conducted to review the literature of antimicrobials used, prescribed and dispensed in PC settings in Pakistan. Google Scholar and Pub-Med were searched for the period 2000–2023. Papers were analyzed on the basis of eligibility i.e., included antimicrobial use, prescribing and dispensing practices by general population at homes, by prescribers in outpatient departments of hospitals and by pharmacists/dispensers in community pharmacies, respectively. Two researchers analyzed the articles thoroughly and disagreements were resolved through discussion with a third reviewer. Both quantitative and qualitative research studies were eligible for inclusion. Additionally, the selected papers were grouped into different themes. We identified 4070 papers out of which 46 studies satisfied our eligibility criteria. The findings revealed limited understanding of antimicrobial resistance (AMR) by physicians and community pharmacists along with inappropriate practices in prescribing and dispensing antibiotics. Moreover, a notable prevalence of self-medication with antibiotics was observed among the general population, underscoring a lack of awareness and knowledge concerning proper antibiotic usage. Given the clinical and public health implications of AMR, Pakistan must prioritize its policies in PC settings. Healthcare professionals (HCPs) need to reduce inappropriate antibiotic prescribing and dispensing, improve their understanding of the AWaRe (access, watch and reserve antibiotics) classification and guidance, monitor current usage and resistance trends, as well as implement antimicrobial stewardship (ASP) activities starting in targeted locations.

X-Ray knee imaging is widely used to detect knee osteoarthritis due to ease of availability and lesser cost. However, the manual categorization of knee joint disorders is time-consuming, requires an expert person, and is costly. This article proposes a new approach to classifying knee osteoarthritis using deep learning and a whale optimization algorithm. Two pre-trained deep learning models (Efficientnet-b0 and Densenet201) have been employed for the training and feature extraction. Deep transfer learning with fixed hyperparameter values has been employed to train both selected models on the knee X-Ray images. In the next step, fusion is performed using a canonical correlation approach and obtained a feature vector that hasmore information than the original feature vector. After that, an improved whale optimization algorithm is developed for dimensionality reduction. The selected features are finally passed to the machine learning algorithms such as Fine-Tuned support vector machine (SVM) and neural networks for classification purposes. The experiments of the proposed framework have been conducted on the publicly available dataset and obtained the maximum accuracy of 90.1%. Also, the system is explained using Explainable Artificial Intelligence (XAI) technique called occlusion, and results are compared with recent research. Based on the results compared with recent techniques, it is shown that the proposed method's accuracy significantly improved. [ABSTRACT FROM AUTHOR]

- Abstract
This study investigates the moderating role of the corruption index with the impacts of foreign direct investment (FDI), unemployment, corruption, and crime rate on economic growth in Bangladesh from 1988 to 2019. The Augmented Dicky-Fuller (ADF) and Phillips-Peron (P-P) unit root tests were applied to check the stationary properties of the concerned variables. The auto regressor distribution lags approach is used to test the hypotheses. The results show that the corruption index as a moderator has a significant adverse impact on economic growth along with the other variables crime, and unemployment on economic growth. To put it simply, economic growth increases by decreasing corruption, unemployment, and crime rates. Similarly, FDI and trade openness appears as a catalyst for boosting economic growth, but the interaction variable of the trade and corruption index increases the trade costs that may slow down the economic growth. As among the pioneer attempts, the present study contributes to growing literature on the moderator role of the corruption index along with other determinants of economic growth by identifying the role of FDI inflows, trade, unemployment, and crime rates on economic growth in Bangladesh. These empirical findings are directed toward some critical policy implications that will help the governmental bodies and policymakers to achieve sustainable economic growth along with ensuring better employment opportunities and thereby control the crime and corruption rates in Bangladesh.

- Abstract
Antimicrobial resistance is of paramount concern globally. Community pharmacists (CPs) play a vital role in supporting judicious antimicrobial use in the community as they are the key healthcare providers at a public level. This study aimed to assess the knowledge, attitude, and perception of CPs towards antimicrobial stewardship at the community level in Saudi Arabia. A self-administered questionnaire was distributed to all community pharmacies in four major cities of Saudi Arabia. A simple random sampling approach was used to select pharmacies in each chain. A total of 520 CPs responded to the survey with a response rate of 98.6 %. Most of the pharmacists (n = 479, 92.1 %) accepted that antimicrobial stewardship programs are essential tools to limit injudicious usage of antimicrobials at the community level. Interestingly, very few (n = 105, 21 %) agreed to recommend antibiotics for common illnesses, including upper respiratory tract infections, cold, and flu without a valid prescription. Further, we found a significant role of Saudi health authorities, e.g., Saudi food & drug authorities and the Ministry of Health, in restricting antimicrobials sale in community pharmacies without a valid prescription. Our study findings revealed that CPs had good knowledge about antimicrobial stewardship in Saudi Arabia. The CPs play an active role in the optimization of antimicrobial therapy and infections caused by different microbes. Strict policies by the Saudi health care authority regarding the restricted dispensing of antimicrobials are welcomed by the CPs and thus may contribute toward lowering of antimicrobial resistance burden on the patients and Saudi health care authorities.

- Abstract
Background: Cardiac resynchronization therapy (CRT) with biventricular pacing (BVP) is well-established therapy in patients with reduced left ventricular ejection fraction (LVEF) and bundle branch block or indication for pacing. Conduction system pacing (CSP) using His-bundle pacing (HBP) or left bundle branch area pacing (LBBAP) has been shown to be a safe and more physiological alternative to BVP.Objective: The purpose of this study was to compare the clinical outcomes between CSP and BVP among patients undergoing CRT.Methods: This observational study included consecutive patients with LVEF ≤35% and class I or II indications for CRT who underwent successful BVP or CSP at 2 major health care systems. The primary outcome was the composite endpoint of time to death or heart failure hospitalization (HFH). Secondary outcomes included subgroup analysis in left bundle branch block as well as individual endpoints of death and HFH.Results: A total of 477 patients (32% female) met inclusion criteria (BVP 219; CSP 258 [HBP 87, LBBAP 171]). Mean age was 72 ± 12 years, and mean LVEF was 26% ± 6%. Comorbidities included hypertension 70%, diabetes mellitus 45%, and coronary artery disease 52%. Paced QRS duration in CSP was significantly narrower than BVP (133 ± 21 ms vs 153 ± 24 ms; P <.001). LVEF improved in both groups during mean follow-up of 27 ± 12 months and was greater after CSP compared to BVP (39.7% ± 13% vs 33.1% ± 12%; P <.001). Primary outcome of death or HFH was significantly lower with CSP vs BVP (28.3% vs 38.4%; hazard ratio 1.52; 95% confidence interval 1.082-2.087; P = .013).Conclusion: CSP improved clinical outcomes compared to BVP in this large cohort of patients with indications for CRT.

- Abstract
Contact resistances play a major role in Joule heating systems. Identifying contact resistances provides a better understanding of the heating process and increases the accuracy of the process models. In this study, contact resistances of the Joule heating section in a powder-epoxy-based towpregging line were explored. For different process parameters, such as production speed, tension, and temperature, contact resistances occurring between metal roller electrodes and dry carbon fibre tows (i.e. without powder-epoxy) were measured to gain an insight into the heating process. Moreover, the effect of contact resistance heating on the temperature profile of the carbon fibre tows was determined with an infrared thermal camera. A simplified finite element model was developed to calculate the temperature distribution onthe carbon fibre tow, which showed a good agreement with the experimental data. Results suggest that contact resistances in the towpregging line were significant and contact resistance heating changed the heating profile.

- Abstract
In the Kingdom of Saudi Arabia, there is an increasing demand for community pharmacists to provide the highest level of clinical knowledge and services. However, evidence regarding Saudi public awareness of the clinical services offered by community pharmacies (CPs) and the barriers to using them is limited. In this cross-sectional study, we used an online questionnaire developed by adapting the Consolidated Framework for Implementation Research. A total of 273 participants completed the survey. Half the participants were generally aware of the availability of some CP services but were not informed about the full range on offer, eg, medication reviews (84%) and online counseling (89%). Most of the participants (69.6%) did not identify differences in the care provided by community pharmacists versus hospital pharmacists (P = 0.02). A commonly reported barrier to using CP services was a general preference for other healthcare professionals to seek pharmaceutical help (85.7%). Many other barriers were also reported, impacting the participants’ use of these services. The decision-making authorities should consider improvements to increase patients’ awareness and utilization of clinical services and enhance community pharmacists’ performance in clinical-oriented pharmaceutical care.

- Abstract
The study aimed to document the quality of work life (QWL) among healthcare staff of intensive care units (ICUs) and emergency units during COVID-19 outbreak using the WHOQoL-BREF. A multicenter cross-sectional study was conducted for two months (May – June 2020) among healthcare staff working in intensive care units (ICUs) and emergency units of the hospitals under the National Guard Health Authority (NGHA) across five cities of Saudi Arabia. The study used the WHOQoL-BREF instrument to document the QWL through an electronic institutional survey. The data was analyzed through IBM SPSS version 23. The study was approved by an ethics committee. A total of 290 healthcare professionals responded to the survey. The mean overall quality of life score was 3.37 ± 0.97, general health = 3.66 ± 0.88, domains, i.e., physical = 11.67 ± 2.16, psychological = 13.08 ± 2.14, social = 13.22 ± 3.31 and environment = 12.38 ± 2.59. Respondents aged > 40 years, male gender, married status, being a physician and, having a work experience > 15 years and no extra working hours, had higher mean scores for several domains of Quality of life (QoL), overall QoL and general health (p < 0.05). The QWL among healthcare staff during COVID-19 pandemic was low. Demographic factors were mainly the determinants for a higher QWL while the variable of extra working hours was a determinant of lower QWL. Despite the pandemic, no COVID-19 related variables affected the work life of healthcare staff. [ABSTRACT FROM AUTHOR]

- Abstract
Healthcare-associated infections (HAI) are considered one of the most common adverse events in health care service provision. In order to prevent the occurrence of HAIs, it is important to implement several prevention strategies. This study aims to determine the incidence of healthcare-associated infections in a military hospital in Alkharj and the adherence to the HAIs' prevention strategies. This study included exporting data for all infected cases confirmed by the infection disease specialists in 2019. The data were collected from the reports that were written by infection control unit and infectious disease department. The rate of healthcare associated infections (HAIs) in 2019 was 0.43% of total patient admissions. The rate of central line associated bloodstream infections in 2019 was 1.15 per 1000 central line days. The rate of catheter associated urinary tract infections in 2019 was 1.00 per 1000 catheter days. The rate of ventilator associated pneumonia in 2019 was 2.11 per 1000 ventilator days and the rate of surgical site infections in 2019 was 0.41 %. The rate of overall healthcare-associated infections (HAI) was low. The compliance rate of health care workers to preventive measures that control HAIs was generally high but there was a need for more awareness particularly regarding personal protective equipment and hand hygiene. So it is important to attend more awareness activities and workshops particularly regarding personal protective equipment and hand hygiene. Furthermore, infection control unit and infectious disease department in the hospital should support the robust HAI prevention programs. [ABSTRACT FROM AUTHOR]

- Abstract
This study aimed to evaluate the concurrent validity of the Arabic version of the General Medication Adherence Scale (GMAS) using two validated scales namely Adherence to Refills and Medications Scale (ARMS) and Medication Adherence Rating Scale (MARS) in Saudi patients with non-communicable diseases. A cross sectional study was conducted for 2 months in out-patient departments at a tertiary care hospital in Khobar, Saudi Arabia. The study collected data from patients with chronic illnesses through convenience sampling. Pearson correlation (ρ) was conducted to report concurrent validity of GMAS. A correlation coefficient value ≥ 0.5 with p-value < 0.01 was considered threshold for establishing concurrent validity. The study was approved by an ethics committee (IRB-2019–05-002). A total of 406 patients responded to the study. The average age was 42.4 ± 5.94 years, and most patients were females (53.7%), married (70%), graduates (65.3%), employed (39.9%) and, had a monthly family income > SAR 10,000, i.e., USD 2666.2 (56.4%). The mean adherence scores obtained from MARS, ARMS and GMAS were 7.09, 19.9, and 27.4. The correlation (ρ) between GMAS and MARS scores was 0.65, and between GMAS and ARMS scores was −0.79, p < 0.01 for both comparisons. The concurrent validity of GMAS-AR was established in this study that would further substantiate psychometric properties of the scale in this population. [ABSTRACT FROM AUTHOR]

- Abstract
The primary objective was to assess beverage consumption pattern and calorie intake among undergraduate students on weekly and daily basis. Secondary objectives were to determine the relationship between demographic variables and beverage intake, assess mean differences in calorie intake between students' groups and, report the predictors of beverage consumption. A cross-sectional study was conducted for 3 months (January–March 2019) among currently enrolled undergraduate students studying in 8 colleges of a public sector university in Dammam, Saudi Arabia. The study used the Arabic version of Beverage Frequency Questionnaire (BFQ) and collected data through purposive stratified sampling. Total intake in ml and calories in kcals were calculated. Data was analyzed through SPSS version 23 and the study was approved from ethics committee of the university (IRB‐2019‐05‐021). A total of 507 students responded to the survey. The average volume of sugar sweetened beverages (SSBs), caffeine containing beverage (CCBs) and carbonated beverages (CarBs) consumed was 4.2 L, 4 L and 1.5 L per week and 650.6 ml, 575.2 ml and 224.6 ml per day, respectively. Average daily calorie intake from SSBs, CCBs and CarBs was 187.6 kcals, 87.6 kcals and 52.5 kcals, respectively. Body mass index (BMI) was significantly related to CCB (ρ = 0.130) and CarBs (ρ = 0.100) intake (mL) (p < 0.05). Mean difference in calorie intake was mostly significant (p < 0.05) when accounted for students' demographics, gender, BMI, residence, illness and, examination time, in case of SSBs, CCBs, CarBs and, all beverages. Averge % contribution towards total daily energy expenditure (TDEE) for SSBs, CCBs and CarBs were 10.2%, 6.3% and 2.8%, respectively. Year of study, BMI, residence and illness were predictors of SSBs consumption while BMI, residence and examination time were predictors of CCBs consumption. Gender and BMI were predictors of CarBs intake. There was a high consumption of beverages in students that was related to their demographic characteristics. There is a need to create awareness among the students regarding the detrimental effects of chronic consumption of these beverages. [ABSTRACT FROM AUTHOR]

- Abstract
Antimicrobial stewardship programs (ASPs) are collaborative efforts to optimize antimicrobial use in healthcare institutions through evidence-based quality improvement strategies. The general administration of pharmaceutical care in the Saudi ministry of health (MOH) is putting outstanding efforts in implementing antimicrobial stewardship in Saudi health care settings. Several surveys have been conducted globally and reported many types of antimicrobial stewardship strategies in health institutions and their effectiveness. This study aims to identify ASPs in Makkah region hospitals and their perceived level of success. We administered a regional survey to explore current progress and issues related to the implementation of ASPs in Makkah region hospitals at the pharmacy level (n = 25). Among responding hospitals, 19 (76%) hospitals, the most commonly reported ASP were as following: formulary restrictions (90%) for broad-spectrum antimicrobials and use of prospective feedback on antimicrobial prescribing (68%), use of clinical guidelines and pathways (100%), and use of automatic stop orders (68%) to limit inappropriate antimicrobial therapy. The study outcomes will also be of pivotal importance to devise policies and strategies for antimicrobial stewardship implementation in other non-MOH settings in the Makkah region. Based on our results, all reported institutions have at least one antimicrobial stewardship program in a process with a high success rate. A multidisciplinary ASP approach, active involvement of drug & therapeutic committee, formulary restrictions, and availability of education & training of pharmacists and physicians on ASP are the primary elements for perceived successful antimicrobial stewardship programs in the Makkah region hospitals.

- Abstract
Osthole (Ost) and icariin (Ica) are extracted from traditional Chinese medicine Cnidium monnieriand Epimedii Folium, respectively, and both exhibit estrogen-like biological activity. This study aimed to determine the efficacy and safety of combining Ost with Ica on the production performance of laying hens and to explore their possible mechanisms. The production performance, egg quality, residues of Ost and Ica in eggs, serum reproductive hormone levels, expression of ovarian reproductive hormone receptor, proliferation of granulosa cells in small yellow follicles (SYF), and progesterone secretion in large yellow follicles (LYF) related genes and proteins expression were detected. The results showed that adding 2 mg/kg Ost + 2 mg/kg Ica to the feed increased the laying rate, average egg weight, Haugh unit, and protein height of laying hens. Serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), and progesterone (P4) levels increased, and the expression of ovarian estrogen receptor (ER), follicle-stimulating hormone receptor (FSHR), and progesterone receptor (PGR) mRNA was up-regulated. Additionally, the mRNA and protein levels of steroidogenesis acute regulatory protein (StAR), cytochrome P450 side-chain cleavage (P450scc), and 3β-hydroxysteroid dehydrogenase (3β-HSD) increased in LYF. Furthermore, mRNA and protein levels of proliferating cell nuclear antigen (PCNA), cyclin E1, and cyclin A2 were up-regulated in SYF. The residues of Ost and Ica in egg samples were not detected by high-performance liquid chromatography (HPLC). In conclusion, dietary supplementation of Ost and Ica increased granulosa cells proliferation in SYF and increased P4 secretion in granulosa cells of LYF, ultimately improving the production performance of laying hens.

- Abstract
The study aimed to translate and validate the Arabic version of General Medication Adherence Scale (GMAS) in Saudi patients with chronic diseases. A multi-center cross sectional study was conducted for a month in out-patient wards of hospitals in Khobar, Dammam, Makkah, and Madinah, Saudi Arabia. Patients were randomly selected from a registered patient pools at hospitals and the item-subject ratio was kept at 1:20. The tool was assessed for factorial, construct, convergent, known group and predictive validities as well as, reliability and internal consistency of scale were also evaluated. Sensitivity, specificity, and accuracy were also evaluated. Data were analyzed using SPSS v24 and MedCalc v19.2. The study was approved by concerned ethics committees (IRB-129-25/6/1439) and (IRB-2019-05-002). A total of 282 responses were received. The values for normed fit index (NFI), comparative fit index (CFI), Tucker Lewis index (TLI) and incremental fit index (IFI) were 0.960, 0.979, 0.954 and 0.980. All values were >0.95. The value for root mean square error of approximation (RMSEA) was 0.059, i.e., <0.06. Hence, factorial validity was established. The average factor loading of the scale was 0.725, i.e., >0.7, that established convergent validity. Known group validity was established by obtaining significant p-value <0.05, for the associations based on hypotheses. Cronbach's α was 0.865, i.e., >0.7. Predictive validity was established by evaluating odds ratios (OR) of demographic factors with adherence score using logistic regression. Sensitivity was 78.16%, specificity was 76.85% and, accuracy of the tool was 77.66%, i.e., >70%. The Arabic version of GMAS achieved all required statistical parameters and was validated in Saudi patients with chronic diseases. [ABSTRACT FROM AUTHOR]

- Abstract
The effect of anticoagulation control on overall Health-Related Quality of Life (HRQoL) in patients taking warfarin in Malaysia has not been explored yet. Therefore, this study aimed to evaluate HRQoL among patients on warfarin in Malaysia. HRQoL among patients on warfarin was measured using WHOQOL-BREF (World Health Organization Quality of life Assessment: Brief Version). Descriptive and inferential statistical analysis was done using Statistical Package for the Social Sciences (SPSS) version 22. Out of 319 patients, more female patients were observed than the males (n = 221, 69.3%, and n = 98, 30.7% respectively). Mean scores for the physical (61.14 ± 15.96), psychological (68.58 ± 16.11), social (63.55 ± 27.06) and environmental domains (62.78 ± 17.58) were observed. Statistically, a significant association was found between the comorbidities other than CVDs with health satisfaction (p = 0.002), physical (p = 0.001), psychological (p < 0.001), social (p = 0.003) and environmental domains of the WHOQOL-BREF. A weak positive correlation between overall health satisfaction and the social domain (r = 0.153) and a moderate positive correlation between the physical and environmental domains (r = 0.628) of the WHOQOL-BREF were observed. Patients had overall better perceived HRQoL scores in the psychological domain as compared with the rest of the domains of the WHOQOL-BREF. Age, gender, employment status, education level, the indication of use and duration of warfarin therapy associated with overall perceived HRQoL. [ABSTRACT FROM AUTHOR]

- Abstract
Surgical site infections are common and expensive infections that can cause fatalities or poor patient outcomes. To prevent these infections, antibiotic prophylaxis is used. However, excessive antibiotic use is related to higher costs and the emergence of antimicrobial resistance. The present meta -analysis aimed to compare the effectiveness of a single dosage versus several doses of antibiotics in preventing the development of surgical site infections. PubMed was used to find clinical trials evaluating the effectiveness of a single dosage versus several doses of antibiotics in avoiding the development of surgical site infections. The study included trials that were published between 1984 and 2022. Seventy-four clinical trials were included in the analysis. Odds ratios were used to compare groups with 95% confidence intervals. The data were displayed using OR to generate a forest plot. Review Manager (RevMan version 5.4) was used to do the meta -analysis. Regarding clean operations, there were 389 surgical site infections out of 5,634 patients in a single dose group (6.90%) and 349 surgical site infections out of 5,621 patients in multiple doses group (6.21%) (OR = 1.11, lower CI = 0.95, upper CI = 1.30). Regarding clean-contaminated operations, there were 137 surgical site infections out of 2,715 patients in a single dose group (5.05%) and 137 surgical site infections out of 2,355 patients in multiple doses group (5.82%) (OR = 0.87, lower CI = 0.68, upper CI = 1.11). Regarding contaminated operations, there were 302 surgical site infections out of 3,262 patients in a single dose group (9.26%) and 276 surgical site infections out of 3,212 patients in multiple doses group (8.59%) (OR = 1.11, lower CI = 0.84, upper CI = 1.47). In general, there were 828 surgical site infections out of 11,611 patients in a single dose group (7.13%) and 762 surgical site infections out of 11,188 patients in multiple doses group (6.81%) (OR = 1.05, lower CI = 0.93, upper CI = 1.20). The difference between groups was not significant. The present study showed that using a single-dose antimicrobial prophylaxis was equally effective as using multiple doses of antibiotics in decreasing surgical site infections. [ABSTRACT FROM AUTHOR]

Ullah, Kifayat and Haseeb, Abdul
- Abstract
Vehicular ad hoc networks (VANETs) unfold the possibilities for a large number of applications. An attractive application is the advertisement of roadside services. Current solutions for the provision of roadside services make use of private cars. However, it would not be possible for the business owners to give incentives to all participating car owners. We proposed a novel protocol for roadside services advertisement using public buses. The road side unit (RSU) broadcast the services to the buses, which store them for a predefined time. We evaluate the performance of our proposed solution in a multi-lane highway scenario. We also compared the performance of our protocol with existing solution under various traffic conditions. The results of our experiments revealed that: (a) broadcast frequency and speed of the buses influenced the advertisement messages received by the buses; (b) by using a broadcast frequency of 5/s, the buses were able to receive all the advertised services.

- Abstract
Melanomacrophagic centers (MMCs) were studied in the liver of zebrafish using transmission electron microscope (TEM). The MMCs were located in the space of Disse (SD), and their pseudopodia protruded into the lumen of sinusoids. The degree of extension of body structure of MMCs in the SD was determined by the size of the phagocytosed content. An irregular or amoeboid nucleus was present. Vacuoles were occasionally present, both, in endothelium and MMCs. The cytoplasm of MMCs showed several engulfed structures. The most common structure was the presence of mitochondria of small to giant size and distorted shape with inconspicuous cristae. The product of mitochondrial degeneration accompanied by lysosomes contributed to the formation of lipofuscins. Besides, changes were also observed in rough endoplasmic reticulum (rER), the Golgi complex, and lysosomes. Occasionally, small to large fragments of the erythrocytes were found in the cytoplasm of MMCs. The rER encompassed the mitochondria and lipid droplets forming a membrane-like structure. Golgi complex were dilated. Lysosomes fused with such membrane-bound structures contributed to the formation of the lipofuscin. The results provide evidence of the role of liver-resident MMCs of zebrafish in phagocytosis of damaged organelles, clearance of the worn-out erythrocytes, and lipofuscin formation.

- Abstract
Lamb–Shaffer syndrome (LAMSHF) is a neurodevelopmental disorder described in just over two dozen patients with heterozygous genetic alterations involving SOX5, a gene encoding a transcription factor regulating cell fate and differentiation in neurogenesis and other discrete developmental processes. The genetic alterations described so far are mainly microdeletions. The present study was aimed at increasing our understanding of LAMSHF, its clinical and genetic spectrum, and the pathophysiological mechanisms involved.

Massive Multiple-Input Multiple-Output (MIMO) is envisioned to be a strong candidate technology for the upcoming 5th generation (5G) of wireless communication networks. This research work presents a novel Compressed Sensing (CS) and Superimposed Training (SiT) based technique for estimating the sparse uplink channels in massive MIMO systems. The proposed technique involves arithmetic addition of a periodic, but low powered training sequence with each user's information sequence. Consequently, separately dedicated resources for the pilot symbols are not needed. Moreover, to attain the estimates of the Channel State Information (CSI) in the uplink, the sparsity exhibited by the MIMO channels is exploited by incorporating CS based Orthogonal Matching Pursuit (OMP) algorithm. For decoding the transmitted information symbols of each user, a Linear Minimum Mean Square Error (LMMSE) based equalizer is incorporated at the receiving Base Station (BS). Based on the obtained simulation results, the proposed SiT-OMP technique outperforms the existing Least Squares (SiT) channel estimation technique. The comparison is done using performance metrics of the Bit Error Rate (BER) and the Normalized Channel Mean Square Error (NCMSE). [ABSTRACT FROM AUTHOR]

Multiple-input multiple-output (MIMO) techniques are foreseen to play a vital role in future 5G cellular networks. This paper presents a novel approach that employs genetic algorithm (GA) to estimate the sparse uplink MIMO channels using superimposed training sequence (SiT). At each transmitter (user) a training sequence is mathematically added with the data bits; thus, avoiding the overhead of dedicated frequency/time slots used for the training. On the receiver side (base station), signals received at all the receive antennas are jointly processed by employing the proposed method to obtain channels' estimate. Then, a linear minimum mean square error (LMMSE) equalizer estimates the data sequences sent by transmitter. A computer simulation based performance analysis of the proposed method is presented, where performance evaluation is done using metrics of normalized channel mean square error (NCMSE), as well as, bit error rate (BER). A comparative analysis of the proposed method with notable SiT least squares (SiT-LS) and SiT-LMMSE methods in the literature is conducted, which clearly demonstrates that the proposed method outperforms both the existing techniques.

Bilal, Muhammad, Haseeb, Abdul, and Rehman, Abdur
- Abstract
Background Polycystic ovary syndrome (PCOS) is the most common endocrine disorder affecting women of reproductive age. The two main documented pathogenic mechanisms are hyperinsulinemia and hyperandrogenemia but there is growing evidence for increased predisposition to cardiovascular disease, dyslipidemia, and type 2 diabetes mellitus. Our study aims to analyze the association of PCOS with cardiovascular risk factors. Methods This is a prospective study which targeted 100 PCOS patients from Civil Hospital Karachi over a period of one year (July 2016 to July 2017). An equal number of age-matched healthy control participants were also included in the study. The student’s t -test was used to assess the significance of differences using SPSS version (19). The statistical significance was set at a p -value of <.05. Results The most frequently presented feature associated with PCOS was primary infertility seen in 72% of the patients. Mean arterial pressure, fasting glucose and insulin levels and insulin resistance was found to be significantly different in PCOS patients as compared to their controls. A classic atherosclerotic lipid profile demonstrating elevated total cholesterol and low-density lipoprotein-C (LDL-C) levels and decreased serum high density lipoprotein-C(HDL-C) was observed in our study. Conclusion This study established a significant yet independent association of PCOS with major cardiovascular risk factors. This association can effectively progress into CVD outcomes which necessitates early intervention programs and preventative strategies to reduce mortality from cardiovascular events. This study lays out the framework for conducting further researches on the PCOS women while exploring novel cardiovascular risk factors. [ABSTRACT FROM AUTHOR]

- Abstract
Telocytes (TCs) have been identified as a distinct type of interstitial cells, but have not yet been reported in the gastrointestinal tract (GIT) of ruminants. In this study, we used transmission electron microscopy (TEM) and double-labelling immunofluorescence (IF) (antibodies: CD34, vimentin and PGP9.5) to seek TCs and investigate their potential functions in the muscle layers of the goat rumen. TCs were distributed widely in the myenteric plexus (TC-MYs) between the circular and longitudinal muscle layers, within circular muscle layers (TC-CMs) as well as in longitudinal muscle layers (TC-LMs). Ultrastructurally, TCs displayed small cell bodies with several long prolongations—telopodes—harboring alternate thin segments (podomers) and dilated segments (podoms). The podoms contained mitochondria, rough endoplasmic reticulum, and caveolae. Telopodes frequently established close physical interactions with near telopodes, collagen fibers (CFs), nerve fibers (NFs), smooth muscle cells (SMCs), nerve tracts, and smooth muscle bundles, as well as with blood vessels (BVs). Furthermore, both homo- and heterotypic connections were observed. In addition, telopodes were capable of releasing extracellular vesicles (EVs). IF analyses proved that TCs were reliably labeled as CD34+/vimentin+ cells, displaying spindle- or triangle-shaped bodies with long prolongations, consistent with TEM results. Specifically, podoms were visible as obvious bright spots. These positive cells covered entire muscular layers, surrounding ganglions, intermuscular BVs as well as entire smooth muscle bundles, forming a network. TC-MYs were distributed as clusters in the external ganglion, encompassing the entire ganglion and spreading to the muscle layers where TC-CMs and TC-LMs seemingly surround whole smooth muscle bundles. TC-MYs were also scattered within the interior of the ganglion, surrounding each ganglionic neuron, following the glial cells layer. We speculate that TCs support the muscle layer structure of the goat rumen and facilitate intercellular signaling directly or indirectly via the TC network.

- Abstract
In this paper, we present a fuzzy logic based scheme for a two hop energy harvesting (EH) wireless sensor network (WSN). Incorporating data and energy causality constraints, discrete transmission rates, finite energy and data buffers, a fuzzy model is developed which uses network throughput, battery level and channel gain as inputs. The fuzzy scheme is then compared with optimum, modified optimum, and Markov decision process (MDP) schemes in terms of computational complexity, throughput, battery level and data buffer capacity. The throughput results show that the fuzzy online scheme preforms closely to the compared schemes and avoids battery depletion even when the number of discrete transmission rates are increased.

Background: Adverse Drug Reactions (ADRs) are a major public health problem. Prompt reporting of suspected ADRs is fundamental in the post-marketing surveillance of medicines and helps in ensuring medicine safety. However, fewer ADRs are reported in general and in particular by community pharmacists. There is limited knowledge about the factors which are preventing community pharmacists in the UK from reporting an ADR. Objectives: To identify the barriers to ADR reporting among community pharmacists practicing in the UK. Methods: A cross sectional study using a 25-items questionnaire (both online and paper based) including 10 barriers to ADR reporting was conducted from 1st April 2012 to September 2012. Community pharmacists practicing in the West Midlands, UK, were approached for the participation in this study. Chi-Square and regression were applied to identify covariates for the barriers to ADR reporting. A significant value of 0.05 was assigned for analysis. Results: Of the 230 invited community pharmacists, 138 pharmacists responded (response rate 60%). The median age of respondents was 31 years. All pharmacists reported that they would report both serious and mild ADRs from drugs with black triangle among children as well as adults. About 95% (n=131) of the pharmacists were familiar with the paper based ADR reporting system. Storebased pharmacists were more likely to be more confident about which ADRs to report [0.680, 95% Confidence Interval 0.43-3.59]. Lack of time 46.4% (n=64), and pharmacists perception that ADR is not serious enough to report (65.2%; n=90) were identified as barriers to ADR reporting. Majority 63.0% (n=87) of the pharmacists identified training and information about what to report and access to Information Technology (IT) (For example access to internet connection) 61.6% (n=85) as facilitators to ADR reporting process. Conclusion: Lack of time and ADRs considered not serious enough by pharmacists to report were barriers to ADR reporting. Further training and education about the types of ADRs to be reported can help to improve the reporting of ADRs. [ABSTRACT FROM AUTHOR]

It is reported in literature that zinc (Zn 2+ ) has antidepressant activity. In present study Zn 2+ was analyzed in blood serum of male patients having various psychiatric disorders (schizophrenia, depression, bipolar). As it is usually present in trace levels. Hence a novel, environmental friendly, dual-cloud point extraction ( d -CPE) method was developed for the enrichment of its trace levels in acid digested serum samples. In the first step of d -CPE, Zn 2+ was complexed with 1-(2-pyridylazo)-2-naphthol (PAN), and the complex was entrapped in a nonionic surfactant (Triton X-114). After achieving cloud point by heating, the mixture was separated into two layers i.e. aqueous and surfactant-rich by centrifugation. In second step of d -CPE, the analyte complex in the surfactant-rich phase was treated wih acid to extract back the metal analytes in acidic aqueous phase, the mixture was again heated upto cloud point and the whole procedure was repeated. This time the aqueous phase, having the metals, was taken and subjected to FAAS using conventional nebulization. The accuracy of the developed methodologies (conventional and d -CPE), were verified by their application to certified reference material of serum (CRM). Reliability of the method was checked by relative standard deviation (%RSD), which was found to be <5%. The limit of detection and limit of quantification were calculated for the proposed method as 1.09 μg/L, and 3.63 respectively and enhancement factor was found to be 40. The developed procedure was successfully applied to the serum samples of patients (male) having different psychiatric disorders and non-psychiatric control subjects for the determination of Zn 2+ .

- Abstract
Endodermal Sinus tumor is a rare malignant type of germ cell tumor (GCT). Primary endodermal sinus tumor, especially in the head of pancreas, is extremely rare. The case under consideration is of a 22 year old male who presented with pancreatic mass causing postprandial nausea and vomiting, and raised AFP levels. The biopsy of the mass revealed the endodermal sinus tumor, and the pancreatic origin was confirmed by a CT scan and a negative scrotal ultrasound. As the tumor was unresectable initially, a gastrojejunostomy was done to relieve the obstructive symptoms. Whipple procedure was performed two months after 4 cycles of BEP chemotherapy to remove the residual tumor in pancreas. It is crucial to highlight this uncommon case in order to increase surgeons' and oncologists' knowledge of the malignant extra-gonadal GCTs diagnosis and treatment. • Primary Pancreatic Endoderm Sinus tumor (EST) is an extremely rare and very malignant form of germ cell tumor • When resectable, tumor excision with tumor free margins and post-operative chemotherapy with PEB is the treatment of choice • EST is very highly responsive to chemotherapy and can be used alone in an unresectable tumor • Moderately high AFP levels should not rule out the diagnosis of EST • EUS-FNA is a gold standard for confirmation of a pancreatic tumor [ABSTRACT FROM AUTHOR]

- Abstract
Background and Aims Patients with cirrhosis may be less than optimal candidates for ERCP because of underlying ascites, coagulopathy, encephalopathy, and other problems. Although the risks of surgery in patients with cirrhosis are well known, few data are available regarding ERCP in patients with cirrhosis. We performed a retrospective, multicenter study of ERCP in patients with cirrhosis to evaluate outcomes, efficacy, and safety. Methods Multicenter retrospective study. Results A total of 538 ERCP procedures were performed on 328 patients with cirrhosis. A total of 229 patients had Child-Pugh (CP) class A, 229 patients had CP class B, and 80 patients had CP class C. Thrombocytopenia and coagulopathy were corrected before ERCP. The 30-day, procedure-related adverse events included post-ERCP pancreatitis (n = 25, 4.6%: 21 mild, 3 moderate, 1 severe), hemorrhage (n = 6, 1.1%), cholangitis (n = 15, 2.8%), perforation (n = 2, 0.4%), aspiration pneumonia (n = 5, 0.9%), bile leakage (n = 1, 0.2%), cholecystitis (n = 1, 0.2%), and death (n = 1, 0.2%). There was a higher incidence of adverse events in patients with CP class B and C disease when compared with those with CP class A disease (11.4%, 11.3%, and 6.1%, respectively; P = .048). There was no correlation between the risk of significant hemorrhage and the presence of coagulopathy or CP class, even in those who underwent a sphincterotomy. The presence of poorly controlled encephalopathy correlated with a higher overall adverse event rate ( P = .003). Sub-analysis revealed that patients without primary sclerosing cholangitis had a significantly higher overall rate of adverse events, pancreatitis, bleeding, and cardiopulmonary adverse events after ERCP when compared with those with primary sclerosing cholangitis. Conclusions Our study was performed on a large series of patients with cirrhosis undergoing ERCP. Overall, the adverse events seen in patients with cirrhosis are similar to those seen in the general population of patients undergoing ERCP, although patients with CP classes B and C have higher adverse event rates compared with those with CP class A. Patients with cirrhosis without primary sclerosing cholangitis had significantly greater adverse event rates when compared with patients with primary sclerosing cholangitis. [ABSTRACT FROM AUTHOR]

This paper proposes an improved Genetic Algorithms (GA) based sparse multipath channels estimation technique with Superimposed Training (ST) sequences. A nonrandom and periodic training sequence is proposed to be added arithmetically on the information sequence for energy efficient channel estimation within the future generation of wireless receivers. This eliminates the need of separate overhead time/frequency slots for training sequence. The results of the proposed technique are compared with the techniques in the existing literature -the notable first order statistics based channel estimation technique with ST. The normalized channel mean-square error (NCMSE) and bit-error-rate (BER) are chosen as performance measures for the simulation based analysis. It is established that the proposed technique performs better in terms of the accuracy of estimated channel; subsequently the quality of service (QoS), while retrieving information sequence at the receiver. With respect to its comparable counterpart, the proposed GA based scheme delivers an improvement of about 1dB in NCMSE at 12 dB SNR and a gain of about 2 dB in SNR at 10
-1 BER, for the population size set at twice the length of channel. It is also demonstrated that, this achievement in performance improvement can further be enhanced at the cost of computational power by increasing the population size. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Objective To determine risk factors for multi-drug-resistant Acinetobacter baumannii(MDR-AB) nosocomial infections in intensive care units in a tertiary care hospital, Makkah, Saudi Arabia.Methods We performed a hospital-based, matched case–control study in patients who were admitted to Al Noor Specialist Hospital between 1 January 2012 and 31 August 2012. The study included cases of A. baumanniinosocomial infection and controls without infection. Controls were matched to cases by age and ward of admission.Results The most frequent site of infection was the respiratory tract (77.3%). Susceptibility to antimicrobial MDR-AB was 92.0% for ceftazidime and ciprofloxacin, while it was 83.3% for imipenem, 83.0% for trimethoprim, 79.0% for amikacin, and 72.7% for gentamicin. Multiple logistic regression of risk factors showed that immunosuppression (OR = 2.9; 95% CI 1.5–5.6; p = 0.002), clinical outcome (OR = 0.4; 95% CI 0.3–0.9; p = 0.01), invasive procedures (OR = 7.9; 95% CI 1.8–34.2; p = 0.002), a central venous catheter (OR = 2.9; 95% CI 1.5–5.6; p = 0.000), and an endotracheal tube (OR = 3.4; 95% CI 1.6–7.3; p = 0.001) were associated with MDR-AB.Conclusions Acinetobacter nosocomial infections are associated with admission to the ICU (Intensive care unit) and exposure to invasive procedures.

- Abstract
Self medication is described as an act of procurement and consumption of medical drugs without the advice of medical physician for diagnosis, prescription and surveillance of treatment. There is a paucity of literature with regards to self medication among rural dwellers of Pakistan and no initiatives have been taken to resolve this issue. Therefore, the study aimed to evaluate frequency, practice and prevalence of self medication among economically deprived rural population of Karachi (South Pakistan). This was the descriptive, epidemiological cross sectional survey which was conducted at the two largest tertiary care government based teaching hospitals of Karachi, Civil hospital and Jinnah Postgraduate Medical Centre, from January 2015 until March 2015. Seven hundred rural dwellers were recruited; who were the residents of outskirts of Karachi city were enrolled in the above mentioned period through the outpatient department (OPD) of the respective hospitals. According to the survey, 595 (85 %) subjects practiced self medication. The most common reasons evaluated for self medication were cost of consultation (90.3 %) and availability of transport (81.0 %) from rural area to health care facility. The paracetamol as a painkiller (93.0 %), acetylsalicylic acid as an anti pyretic (69.0 %), anti biotic (52.0 %) and anti allergic (51.0 %) were the commonest drug used without prescription of a health care physician. A significant difference was obtained in carrying out self medication between participants earning less than 50,000 PKR and greater than this amount (p= 0.029; 61 % vs. 24 %) and for the self medicated patients having education less than graduation with the participants having education of graduation or above it (p= 0.03; 63 % vs. 22 %). The self medication among rural dwellers of Karachi is high . As a result, urgent steps must be taken to initiate the awareness and educational programs regarding potential risks of self medication. Secondly, strict measures must be introduced to stop supply of prescription drugs from pharmacies without prescription. Thirdly, provision of cost effective treatment from public sector hospitals to rural population can help to reduce self medication among rural population of Pakistan.
