Trends, safety, and efficacy of wearable male sexual devices.

INTRODUCTION: The prevalence of male sexual dysfunction (MSD) increases with age, with >50% of men aged >40 years reporting erectile dysfunction (ED). In recent years, wearable male sex devices (WMSDs) have been increasingly utilized by patients and recommended by sexual medicine clinicians. OBJECTIVES: This study seeks to investigate the safety and efficacy of products currently marketed for the treatment of MSD. METHODS: Available products for WMSDs were reviewed by analyzing product websites, forums, advertisements, and clinical recommendations. Qualitative comparisons were based on patient reviews, cost, and specific features. Investigatory evidence and Food and Drug Administration status were also reviewed. Additionally, Google Trends was used to determine the popularity of devices over time. RESULTS: Eight WMSDs for the treatment of MSD and enhancement of sexual pleasure were reviewed. Constriction bands, such as the Maintain Ring Loop, Eddie by Giddy, and Xialla, have shown significant benefits in clinical trials and were the most popular devices among patients. Smart devices can provide real-time feedback on erectile quality and/or sexual performance. Similar to the RigiScan, the Adam sensor provides feedback on erectile quality while monitoring changes in penile tumescence during sleep with additional analysis available through a mobile application. Neuromodulation devices such as the Morari Patch and vPatch/in2 Patch use electrical stimulation to delay ejaculation and improve sexual function. The FirmTech Performance Ring uses sensors to track the vital signs of erectile fitness with clinical trials ongoing. CONCLUSIONS: Overall, this review describes the available investigatory evidence for a range of WMSDs and highlights the potential benefits and limitations of these devices in treating MSD and enhancing sexual pleasure. Further research is needed to evaluate the effectiveness of these devices and to determine which ones may be the most suitable for individual patients.

A State-of-the-Art Review on Structural Strengthening Techniques with FRPs: Effectiveness, Shortcomings, and Future Research Directions.

In the pursuit of creating more sustainable and resilient structures, the exploration of construction materials and strengthening methodologies is imperative. Traditional methods of relying on steel for strengthening proved to be uneconomical and unsustainable, prompting the investigation of innovative composites. Fiber-reinforced polymers (FRPs), known for their lightweight and high-strength properties, gained prominence among structural engineers in the 1980s. This period saw the development of novel approaches, such as near-surface mounted and externally bonded reinforcement, for strengthening of concrete structures using FRPs. In recent decades, additional methods, including surface curvilinearization and external prestressing, have been discovered, demonstrating significant additional benefits. While these techniques have shown the enhanced performance, their full potential remains untapped. This article presents a comprehensive review of current approaches employed in the fortification of reinforced cement concrete structures using FRPs. It concludes by identifying key areas that warrant in-depth research to establish a sustainable methodology for structural strengthening, positioning FRPs as an effective replacement for conventional retrofitting materials. This review aims to contribute to the ongoing discourse on modern structural strengthening strategies, highlight the properties of FRPs, and propose avenues for future research in this dynamic field.

Molecular and metabolic characterization of petroleum hydrocarbons degrading Bacillus cereus.

Hydrocarbon constituents of petroleum are persistent, bioaccumulated, and bio-magnified in living tissues, transported to longer distances, and exert hazardous effects on human health and the ecosystem. Bioaugmentation with microorganisms like bacteria is an emerging approach that can mitigate the toxins from environmental sources. The present study was initiated to target the petroleum-contaminated soil of gasoline stations situated in Lahore. Petroleum degrading bacteria were isolated by serial dilution method followed by growth analysis, biochemical and molecular characterization, removal efficiency estimation, metabolites extraction, and GC-MS of the metabolites. Molecular analysis identified the bacterium as Bacillus cereus, which exhibited maximum growth at 72 hours and removed 75% petroleum. Biochemical characterization via the Remel RapID™ ONE panel system showed positive results for arginine dehydrolase (ADH), ornithine decarboxylase (ODC), lysine decarboxylase (LDC), o-nitrophenyl-ß-D-galactosidase (ONPG), p-nitrophenyl-ß-D-glucosidase (ßGLU), p-nitrophenyl-N-acetyl-ß-D-glucosaminidase (NAG), malonate (MAL), adonitol fermentation (ADON), and tryptophane utilization (IND). GC-MS-based metabolic profiling identified alcohols (methyl alcohol, o-, p- and m-cresols, catechol, and 3-methyl catechol), aldehydes (methanone, acetaldehyde, and m-tolualdehyde), carboxylic acid (methanoic acid, cis,cis-muconic acid, cyclohexane carboxylic acid and benzoic acid), conjugate bases of carboxylic acids (benzoate, cis,cis-muconate, 4-hydroxybenzoate, and pyruvate) and cycloalkane (cyclohexene). It suggested the presence of methane, methylcyclohexane, toluene, xylene, and benzene degradation pathways in B. cereus.

Obesity and cardiovascular health.

Obesity has risen to epidemic levels worldwide over the past few decades and has become a huge global health burden owing to its direct contribution to the development of some of the most prevalent chronic diseases including diabetes, hypertension, hyperlipidaemia, and other cardiovascular diseases. Obesity is a disease of positive energy balance resulting from complex interactions between abnormal neurohumoral responses and an individual's socioeconomic, environmental, behavioural, and genetic factors leading to a state of chronic inflammation. Understanding the complex nature of the disease is crucial in determining the best approach to combat its rising numbers. Despite recent advancements in pharmacological therapy for the treatment of obesity, reversing weight gain and maintaining weight loss is challenging due to the relapsing nature of the disease. Prevention, therefore, remains the key which needs to start in utero and continued throughout life. This review summarizes the role obesity plays in the pathophysiology of various cardiovascular diseases both by directly affecting endothelial and myocyte function and indirectly by enhancing major cardiovascular risk factors like diabetes, hypertension, and hyperlipidaemia. We highlight the importance of a holistic approach needed to prevent and treat this debilitating disease. Particularly, we analyse the effects of plant-based diet, regular exercise, and non-exercise activity thermogenesis on obesity and overall cardiorespiratory fitness. Moreover, we discuss the significance of individualizing obesity management with a multimodal approach including lifestyle modifications, pharmacotherapy, and bariatric surgery to tackle this chronic disease.

Missed opportunities to prevent hypertension at a tertiary care centre in Pakistan.

Background: Cardiovascular disease is the leading cause of mortality worldwide, affecting ~1.28 billion adults, and ~46% of these adults are not aware of their condition. One-third of patients do not receive appropriate care for their cardiovascular disease. Aim: To identify missed opportunities to prevent cardiovascular disease and its associated risk factors. Methods: This study was conducted among 359 adult patients aged 18-77 years leaving the outpatient department of Civil Hospital, Karachi, Pakistan, during June to September 2020. We recorded their sociodemographic information, perceived duration of clinical consultation, body weight and height, and blood pressure. We investigated if their physicians obtained sufficient medical history, performed medical examination, or counselled them on cardiovascular disease risk factors. Data were analysed using SPSS version 24.0. Results: Almost all the participants (98%) had at least 1 risk factor for hypertension. Only 35.9% of those in the highrisk group with ≥ 3 risk factors received counselling from a physician about their hypertension, leaving a 37.6% missed opportunity rate. Conclusion: The frequency of missed opportunities for the prevention of cardiovascular disease, and the risk factors for hypertension were high among the study population. This was partly due to excess workload of the attending physicians; the outpatient departments were used more for the treatment of general ailments than for specialist and referral care. It is recommended to establish primary care clinics within the tertiary settings where cardiovascular risk factors can be evaluated and patients referred for appropriate care.

Security Framework for Network-Based Manufacturing Systems with Personalized Customization: An Industry 4.0 Approach.

Smart manufacturing is pivotal in the context of Industry 4.0, as it integrates advanced technologies like the Internet of Things (IoT) and automation to streamline production processes and improve product quality, paving the way for a competitive industrial landscape. Machines have become network-based through the IoT, where integrated and collaborated manufacturing system responds in real time to meet demand fluctuations for personalized customization. Within the network-based manufacturing system (NBMS), mobile industrial robots (MiRs) are vital in increasing operational efficiency, adaptability, and productivity. However, with the advent of IoT-enabled manufacturing systems, security has become a serious challenge because of the communication of various devices acting as mobile nodes. This paper proposes the framework for a newly personalized customization factory, considering all the advanced technologies and tools used throughout the production process. To encounter the security concern, an IoT-enabled NBMS is selected as the system model to tackle a black hole attack (BHA) using the NTRUEncrypt cryptography and the ad hoc on-demand distance-vector (AODV) routing protocol. NTRUEncrypt performs encryption and decryption while sending and receiving messages. The proposed technique is simulated by network simulator NS-2.35, and its performance is evaluated for different network environments, such as a healthy network, a malicious network, and an NTRUEncrypt-secured network based on different evaluation metrics, including throughput, goodput, end-to-end delay, and packet delivery ratio. The results show that the proposed scheme performs safely in the presence of a malicious node. The implications of this study are beneficial for manufacturing industries looking to embrace IoT-enabled subtractive and additive manufacturing facilitated by mobile industrial robots. Implementation of the proposed scheme ensures operational efficiency, enables personalized customization, and protects confidential data and communication in the manufacturing ecosystem.

Factors Related to Anemia Prevalence Among Women of Childbearing Age in the Period of Global Pandemic.

Background Health authorities in Pakistan in collaboration with local and foreign non-government organizations are working hard to achieve the targets set by World Health Organization in 2012, that is, to reduce anemia prevalence and its related factors. However, due to the prevailing COVID-19 crisis, all resources and attention were diverted toward it, which led to ignorance of existing basic health issues. Objective This study assesses anemia prevalence and its related factors among women of childbearing age in the period of global pandemic. Methods A time-lagged, cross-sectional survey was conducted using a self-administered questionnaire among 1,702 volunteer women aged between 15 and 49 years across five major cities of Pakistan from January 2021 to December 2021 using the non-probability consecutive sampling technique. Blood sample results were analyzed to determine prevalence and anemia severity. The chi-squared test and multiple logistic regression were performed to examine the relationship and effect of related factors with hemoglobin levels using SPSS version 26. Results Among the 1,702 respondents, 788 (46.3%) were non-anemic and 914 (53.7%) were anemic. Anemia prevalence in Karachi was slightly greater (n=294, 55.48%) compared to other cities, and the mean hemoglobin level was 11.98 ± 0.92 g/dL. The chi-square test and multiple logistic regression indicated that the respondents' employment status, mother's profession, family income, living conditions, chronic health conditions, use of iron and folic acid supplements, junk food, source of drinking water, and knowledge about anemia and its preventive measures were associated significantly with anemia during the pandemic. Conclusion Results confirmed that anemia is a multi-factor health problem and that it was totally ignored during the COVID-19 pandemic, as the prevalence increased during the pandemic. Therefore, more attention should be paid to anemia surveillance, anemia awareness programs, and mobilization of community health workers and volunteers to reach a wide range of the population, including women of childbearing age even during the pandemic.

Risk Stratification of Acute-Onset Chest Pain: SVEAT Score Versus HEART and TIMI Scores.

Introduction Acute chest pain is a frequently encountered symptom in the emergency department. Despite the availability of various chest pain risk scores, their effectiveness in identifying low-risk patients suitable for safe and early discharge is inadequate. Moreover, clinical data collected at the initial stage, which has valuable discriminatory ability, is often underutilized. This study aims to assess the effectiveness of the Symptoms, history of Vascular disease, ECG, Age, and Troponin I (SVEAT) score in predicting major adverse cardiovascular events (MACE) in acute-onset chest pain, compared with the pre-existing History, ECG, Age, Risk factors, and Troponin I (HEART) and Thrombolysis In Myocardial Infarction (TIMI) scores. Methodology This prospective study utilizing non-probability convenience sampling was conducted in the emergency medicine department of a tertiary care hospital in Rawalpindi, Pakistan, for a period of five months from July 2022 to November 2022. The study included patients aged >45 years who presented primarily with chest pain lasting for at least five minutes but less than 24 hours and with a lack of acute ECG changes indicative of ST-elevation acute coronary syndrome (STE-ACS). Patients who were hemodynamically unstable were excluded. All patients were assessed for the calculation of SVEAT, TIMI, and HEART scores. All patients were followed for a period of 30 days to assess the incidence of MACE. Results A total of 60 patients were included. The mean age was 61.5±9.1 years while 31 (51.7%) patients were females. Diabetes was the most prevalent comorbidity (n=32; 53.3%). Regarding MACE, nine (15%) patients developed ACS and underwent percutaneous coronary intervention (PCI). Two patients (3.3%) experienced heart failure. Six (10%) patients also underwent PCI in the absence of ACS while two (3.3%) patients developed sudden cardiac death. Area-under-curve (AUC) values were determined for SVEAT (0.843; 95%CI: 0.74-0.94), TIMI (0.742; 95%CI: 0.62-0.86), and HEART scores (0.840; 95%CI: 0.74-0.94). A cut-off level of 3.5 SVEAT points obtained a sensitivity of 63.2% and specificity of 75.6% in predicting 30-day MACE. Conclusion SVEAT score potentially lacks the appropriate sensitivity level to predict a significant number of major adverse cardiovascular events compared to contemporary risk stratification scores. Therefore, the SVEAT criteria need re-evaluation as a screening tool for risk assessment in acute chest pain.

Current Practices and Perceived Role of Community Pharmacists in Type 2 Diabetes Services in Pakistan.

Background Diabetes mellitus is a chronic illness which is becoming more prevalent in developing countries, and it is being managed mostly in hospitals or clinics in underdeveloped nations. Other strategies for treatment delivery in emerging nations must be considered as the number of diabetic patients grows. Community pharmacists are a valuable choice for diabetes care. However, only developed countries have data on community pharmacists' diabetes treatment practices. Methodology A non-probability consecutive sampling strategy was used to gather a self-administered questionnaire from 289 community pharmacists. Six points Likert scale was employed to score current practices and pharmacists' perceived role. A response rate of 55% was attained. Characteristics associated with present behaviors and perceived roles were analyzed using Chi-square and logistic regression. Results The majority of the respondents were males, 234 (81.0%). Out of 289, 229 (79.2%) were of 25-30 years of age and were pharmacists as well as qualified persons (QP) 189 (65.4%). A QP is one who has the legal authority to sell drugs to customers. The majority had <5 years of working experience as a community pharmacist, 268 (92.7%), and did not have diabetes training, 237 (82.0%). Most community pharmacies were stand-alone, 110 (38.1%), and had a single or a group of proprietors, 248 (85.8%). Open hours of most of the pharmacies were 16-20 hours per day, 202 (69.8%), and most had one pharmacist, 243 (84.1%), i.e., working as a pharmacist as well as a qualified person. Approximately 203 (70.2%) of the pharmacies had customers >2000 in a month and >100 customers purchased anti-diabetes medications per month. Only 44 (15.2%) community pharmacies had a designated room or space for patient counselling. The majority of pharmacists were also in favor of providing services other than dispensing such as counselling the patients about prescribed medicines, direction of use, use of devices for insulin administration, training on self-monitoring of glucose, and healthy lifestyle and diet practices. Pharmacy setting, ownership, patient counseling area, and the number of customers per month were key factors in the provision of diabetes services. The main obstacles identified were a lack of pharmacist availability and academic competency. Conclusion In Rawalpindi and Islamabad, most community pharmacies only provide a basic dispensing service for diabetes patients. Most of the community pharmacists agreed to extend their duties. The expansion of pharmacist professional responsibilities would help control the rising diabetes burden. The facilitators and hurdles identified would serve as a foundation for the introduction of diabetic care in community pharmacies.

Aftermath of the COVID-19 Pandemic on Mental Health and Well-Being of Patients With Thalassemia Major in Pakistan: A Qualitative Study.

Background and aim Chronic patients with thalassemia major were mainly recognized as more prone to poor mental health during this global pandemic. This study aims to evaluate causal relationships leading to poor outcomes and how they manage to tackle this. Methods In-depth face-to-face semi-structured interviews were conducted with 21 thalassemia patients selected through probability consecutive sampling from Pakistan Thalassemia Welfare Society Centers. The following criteria served as the basis for the interview: (1) solitude at home, (2) interruption of transfusion services, (3) alteration of appetite and interests, (4) lack of control and uncertainty, (5) extensive media coverage, (6) deterioration of pre-existing health issues, difficulty in sleeping, (7) practicing gratitude, (8) participation in activities and hobbies, (9) connectivity with others, and (10) ability to recognize social support. All interviews were recorded, transcribed, and analyzed with reflexive thematic analysis. Results The commonly described mental health conditions were depression and concern about the overall health status. The following seven elements associated with the pandemic contributed to the deterioration of mental health: (1) isolation at home, (2) disruption in transfusion services, (3) change in appetite and interests, (4) lack of control and uncertainty, (5) intensive media reporting, (6) worsening of pre-existing health problems, and (7) difficulty in sleeping. The following four coping strategies were identified for maintaining mental issues: (1) practicing gratitude, (2) involvement in activities and hobbies, (3) connectivity with others, and (4) discerning social support. Conclusions Thalassemia major patients had been negatively affected during the pandemic. Only a small number of people modified their management techniques to maintain steady well-being.

The Impact of Dynamic Real-Time Feedback on Patient Satisfaction Scores.

INTRODUCTION: Providers' communication skills have a significant impact on patients' satisfaction. Improved patients' satisfaction has been positively correlated with various healthcare and financial outcomes. Patients' satisfaction in the inpatient setting is measured using the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey. In this study, we evaluated the impact of dynamic real-time feedback to the providers on the HCAHPS scores. METHODS: This was a randomized study conducted at our 550-bed level-1 tertiary care center. Twenty-six out of 27 hospitalists staffing our 12 medicine teams (including teams containing advanced practice providers (APPs) and house-staff teams) were randomized into intervention and control groups. Our research assistant interviewed 1110 patients over a period of 7 months and asked them the three provider communication-specific questions from the HCAHPS survey. Our intervention was a daily computer-generated email which alerted providers to their performance on HCAHPS questions (proportions of "always" responses) along with the performance of their peers and Medicare benchmarks. RESULTS: The intervention and control groups were similar with regard to baseline HCAHPS scores and clinical experience. The proportion of "always" responses to the three questions related to provider communication was statistically significantly higher in the intervention group compared to the control group (86% vs 80.5%, p-value 0.00001). It was also noted that the HCAHPS scores were overall lower on the house-staff teams and higher on the teams with APPs. CONCLUSION: Real-time patients' feedback to inpatient providers with peer comparison via email has a positive impact on the provider-specific HCAHPS scores.

Knowledge, Attitudes, Anxiety, and Preventive Behaviors Related to COVID-19 Among Healthcare Providers: A Developing Country's Perspective.

Background In early 2020, the rapid global spread of coronavirus disease 2019 (COVID-19) presented healthcare workers (HCWs) with an unprecedented challenge. The constant influx of new information about the virus created knowledge gaps, and the relentless demands of their work schedules left many feeling overwhelmed. This paper explores the knowledge, attitudes, anxiety levels, and preventive behaviors of HCWs in the twin cities of Pakistan, Rawalpindi and Islamabad, related to the COVID-19 pandemic. In the face of this crisis, it is essential to gain insights into the experiences and needs of these frontline heroes. Methodology We conducted a descriptive web-based cross-sectional study among healthcare professionals to delve into the multifaceted aspects of their experiences. This included analyzing sociodemographic characteristics, knowledge levels, attitudes, practices, and the psychological implications of the pandemic. By employing both quantitative and qualitative analysis, we aimed to provide a comprehensive understanding of these parameters. Results Out of the 1150 responses collected, it became evident that breathing problems were the most recognized symptom of COVID-19 among HCWs. Impressively, 95.7% of participants believed in the primarily symptomatic nature of treatment, although 37% held the misconception that antibiotics were effective against the virus. Another noteworthy discovery was that 68.2% of HCWs favored testing before initiating treatment, yet a concerning 22.7% of treated patients received no testing. A significant proportion, approximately 19.6%, experienced heightened anxiety levels during the pandemic, leading to an increased frequency of handwashing. In terms of preventive behaviors, a majority of respondents displayed a heightened sense of caution. Nearly 59.1% reported avoiding the use of others' accessories and emphasized not reusing face masks. Furthermore, 84.1% of participants preferred staying at home during quarantine. Conclusion The study reveals the profound impact of COVID-19 on healthcare providers in Pakistan's twin cities, highlighting elevated anxiety levels among most. This underscores the urgent need for mental health support. Beyond physical effects, the pandemic significantly strains their psychological well-being. To address this stress, vital strategies include workload reduction, structured shifts, stressor minimization, and improved knowledge sharing. Cultivating a healthy work environment is equally crucial for healthcare providers' overall well-being. These insights are essential for crafting policies and interventions to better protect and support frontline workers in a developing nation like Pakistan, demonstrating healthcare professionals' resilience and dedication amid unprecedented challenges.

Frequency of Thyroid Gland Invasion by Laryngeal Squamous Cell Carcinoma: The Role of Subglottic Extension

Abstract Introduction Management of the thyroid gland during laryngectomy has been controversial. The primary tumor may invade the thyroid gland by direct invasion or lymphovascular spread. Hypothyroidism and hypoparathyroidism are potential risks when lobectomy or total thyroidectomy are performed simultaneously. Objective To report the frequency of thyroid gland involvement by primary laryngeal squamous cell carcinoma in patients undergoing laryngectomy and to identify possible risk factors for thyroid gland involvement so that judicious excision of thyroid gland can be attained. Methods We performed a retrospective review of 9 years. Data was collected from medical records of patients dated from December 2009 to October 2018. All patients with laryngeal cancer who underwent laryngectomy with lobectomy or total thyroidectomy were included in the present study. Results We reviewed 151 laryngectomy records. A total of 130 surgeries included the thyroid gland with the excised specimen and were available for analysis. There were 124 males and 6 females. The mean age was 59.4 years old. The glottis was the most common subsite involved, in 70 patients, followed by 38 transglottic, 16 supraglottic and 03 subglottic tumors. On histology, 12 out of 130 excised thyroid glands were involved by squamous cell carcinoma. Only subglottic involvement (p = 0.01) was significantly associated with thyroid gland invasion (TGI). Type of laryngectomy, subsite of the primary tumor, thyroid cartilage involvement, neck nodal metastases, and perineural and lymphatic invasion by the primary tumor were not associated with TGI. Conclusion Only subglottic involvement is associated with TGI; therefore, preoperative and intraoperative assessment is necessary prior to considering excision of the thyroid gland.

Vaccine-induced immune thrombotic thrombocytopenia in a male after Ad26.COV2.S vaccination presenting as cerebral venous sinus thrombosis.

Vaccine-induced immune thrombotic thrombocytopenia (VITT) is a rare and life-threatening complication that can occur after COVID-19 vaccination. After the first reports of VITT and CVST in 2021 after Ad26.COV2.S vaccination, the FDA and CDC recommended an emergency pause on 13 April 2021, and after extensive safety reviews, on 23 April 2021, the CDC's Advisory Committee on Immunization Practices (ACIP) reaffirmed its original recommendation for use of the Ad26.COV2.S vaccination. As of 31 August 2021, in the United States, 54 cases of VITT following Ad26.COV2.S vaccination (37 female, 17 male) have been reported out of 14.1 million total shots given, 29 of which had cerebral venous sinus thrombosis (CVST). With more data, on 16 December 2021, the CDC endorsed the ACIP recommendations for individuals to receive an mRNA COVID-19 vaccine in preference over the Ad26.COV2.S vaccination. We report a rare case of a male with confirmed VITT and CVST following Ad26.COV2.S vaccination.

Bacteriocin-mediated inhibition of some common pathogens by wild and mutant Lactobacillus species and in vitro amplification of bacteriocin encoding genes.

Lactobacilli are the most common probiotics used in food and other industries because of their capability of producing bacteriocins. Bacteriocins are compounds that are used to kill pathogenic microorganisms. As most bacteria have become resistant to synthetic antibacterial tools, the importance of using probiotics as antibacterial agents has increased. This work was done to check the bacteriocin effect on some common pathogens and the influence of mutation on the bacteriocin activity of Lactobacilli was also investigated. Four strains were isolated, identified from meat and pickles samples via culturing methods, staining, biochemical tests, and ribotyping. Preliminary tests, including Gram staining and catalase test, were done for the confirmation of Lactobacillus species. All strains were gram-positive and catalase-negative. Antibacterial activity was checked against Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus thuringiensis, Escherichia coli, and Salmonella enteritis via agar well diffusion method. The mutations were done using ethidium bromide and the influence of wild and mutants were also checked. Interestingly, mutants developed more virulence than wild ones. It was also observed that they all were sensitive to pepsin. Protein estimation was done via Bradford method. Ribotyping of GCU-W-PS1 revealed 99 % homology with Lactobacillus plantarum and GCU-W-MS1 to Lactobacillus curvatus (99 % homology). Curvacin A, sakacin P, and plantaricin A genes were also amplified using specific primers. Gene sequence showed the presence of curvacin A gene in GCU-W-MS1. It was concluded that lactic acid bacteria could be used as antibacterial tools against common pathogens.

Neutrophil-to-Lymphocyte Ratio and Absolute Lymphocyte Count as Early Diagnostic Tools for Corona Virus Disease 2019.

Background and objectives In comparison to real-time polymerase chain reaction (RT-PCR) testing, blood-related parameters including absolute lymphocyte count (ALC) and neutrophil-to-lymphocyte ratio (NLR) carry an indeterminate potential in the assessment of corona virus disease 2019 (COVID-19). Our main objective was to assess their efficacy in timely identification of COVID-19 patients and to determine whether these biomarkers can be employed as an early diagnostic tool in patients presenting with symptoms suggestive of COVID-19. Methodology This cross-sectional study was conducted at the Emergency Department of a Tertiary Care Hospital in Rawalpindi, Pakistan from November 2020 to March 2021. Patients suspected to have COVID-19 on a clinical basis (fever, cough or shortness of breath) were selected by using convenience non-probability sampling. RT-PCR was used to diagnose COVID-19 after evaluating NLR and ALC of the sample population. An NLR = 3.5 and ALC < 1 x 103 cells/mm3 was considered as the cut-off value. Statistical analysis was conducted via SPSS 23.0 (IBM Corp., Armonk, NY). Chi-square and independent t-tests were used to correlate various data variables, while p-value <0.05 was considered significant. Results Out of the 172 subjects included in the study, the mean age was 40.6 ± 10.0 years, while 51% of individuals were males. Fever was found to be the most prevalent complaint (94%). Double RT-PCR testing showed that 51.2% of the population was RT-PCR positive, having a mean ALC of 1.4 ± 0.9 x 103/mm3, significantly lower than RT-PCR negative cases (p < 0.001). In addition, NLR was drastically elevated for RT-PCR-positive individuals (p < 0.001) while it also had a distinctly high specificity of 91.7% among COVID-19 patients. Additionally, NLR did not correlate with any of the baseline patient-related parameters (presenting complaint, age, and gender). Conclusion NLR and ALC are potentially efficacious measures for an early diagnosis of COVID-19, and can be possibly utilized for an early diagnosis of COVID-19 suspects.

Clone-advisor: recommending code tokens and clone methods with deep learning and information retrieval.

Software developers frequently reuse source code from repositories as it saves development time and effort. Code clones (similar code fragments) accumulated in these repositories represent often repeated functionalities and are candidates for reuse in an exploratory or rapid development. To facilitate code clone reuse, we previously presented DeepClone, a novel deep learning approach for modeling code clones along with non-cloned code to predict the next set of tokens (possibly a complete clone method body) based on the code written so far. The probabilistic nature of language modeling, however, can lead to code output with minor syntax or logic errors. To resolve this, we propose a novel approach called Clone-Advisor. We apply an information retrieval technique on top of DeepClone output to recommend real clone methods closely matching the predicted clone method, thus improving the original output by DeepClone. In this paper we have discussed and refined our previous work on DeepClone in much more detail. Moreover, we have quantitatively evaluated the performance and effectiveness of Clone-Advisor in clone method recommendation.

Adenoid cystic carcinoma of external auditory canal: A rare disease.

External auditory canal, like other epithelialized surfaces is predisposed to malignancies such as Squamous cell carcinomas (SCC), melanomas and adenocarcinomas. In this background, malignancies like adenoid cystic carcinoma (ACC) are a rare occurrence and need to be thoroughly evaluated both locally and for distant extension. The malignancy needs to be addressed with an aggressive approach surgically with adequate marginal clearance. The role of radiation is debatable considering the outcomes in the limited data. Here we present the case of a 35-year-old female who came in with otalgia and otorrhea associated with a mass in the external auditory canal. After biopsy and imaging, a diagnosis of adenoid cystic carcinoma was made and the patient was managed accordingly.
