BACKGROUND & OBJECTIVE: Kisspeptin (KP) and spexin (SPX) are neuropeptides that play a substantial role in metabolism and sexual function. Our objective is to explore the association of spexin and kisspeptin with sperm parameters and lipid profile in the infertile male population.

METHODOLOGY: The cross-sectional study was conducted from March 2017 till July 2018 in Aga Khan University Hospital, Karachi, Pakistan, after acquiring ethical approval (4813-BBS-ERC-17). Convenient sampling was applied to recruit 44 normozoospermic subjects as controls and 44 patients with abnormal sperm parameters”. Serum levels of kisspeptin and spexin were measured by enzyme linked immunosorbent assay and Cobas c111 analyzer was used for estimation of high and low density-lipoprotein, triglyceride and serum cholesterol levels. Mann-Whitney U tests and spearman’s rank correlation test were used to analyze quantitative variables, and data was presented by means, standard error (SE) and correlations coefficient, with a statistical significance set at p≤0.05.

RESULTS: The mean kisspeptin values of ‘altered sperm parameters’ males 13.23 ± 3.34 were lower than normal sperm parameters 31.89 ± 3.25 (p<0.001). The mean spexin values of altered sperm parameters 383.57 ± 21.09 were less than compared to normal sperm parameters 502.76 ± 19.77 (p<0.001). Correlation of KP and SPX levels was (r-value = 0.332, p= 0.002). There was no significant correlation was found between KP and SPX with lipid profile parameters.

CONCLUSION: Spexin and kisspeptin levels observed were higher in male subjects with normal sperm parameters and had a significant positive correlation with each other. There was no impact of spexin on lipid profile and obesity.

BACKGROUND & OBJECTIVE: Chronic Obstructive Pulmonary Disease (COPD) is a heterogeneous disease, showing the exaggerated response of airways to any injurious stimulus. It is no longer considered as the disease of men as it is becoming increasingly prevalent in females. Evidence suggests that gender affects the clinical presentation of the disease. The objectives of the study is to compare spirometry data between male and female smokers with COPD and to study the association of cough, sputum, and dyspnea with gender in smokers with COPD.

METHODOLOGY: This descriptive study was conducted at the University of Health Sciences Lahore. The study sample included 41 COPD patients with a history of smoking. After taking written informed consent, patients were recruited from the outpatient departments of tertiary care hospitals of Lahore by convenience sampling technique. A complete history was taken, and spirometry was done on each subject. The subjects were divided into male and female groups, followed by the comparison of Spirometry data between the groups and association of symptoms with gender using appropriate statistical techniques.

RESULTS: The results of this study demonstrated females were significantly younger and exhibited a greater decline of lung functions with similar pack-years history compared to male smokers with COPD. The most common presentation of females was breathlessness compared to male patients, who had sputum production as the most common presentation.

CONCLUSION: Significant differences were seen in spirometry and clinical presentation of the disease in male and female COPD groups, showing the onset and symptomology of the disease.

Published: November 2021

BACKGROUND & OBJECTIVE: The pathology of acne is vaguely understood to date, current epidemiologic evidence in Eastern populations indicates that consumption of chocolate, milk intake, fatty products, and glycemic load may be involved. Previously little research has been conducted highlighting the possible relationship between diet and acne among patients in Pakistan. The objective of this study was to identify the association of acne vulgaris and dietary intake patterns.

METHODOLOGY:  An observational study enrolled 246 participants, both genders, 16 to 40 years of age, diagnosed with Acne Vulgaris recruited from a tertiary-care hospital out-patient clinic in Karachi. The structured questionnaire consisted of various methods for assessing nutritional parameters.  Statistical analysis was carried out using SPSS, the association of Acne was tested with dietary habits using Pearson-Chi Square test. Food items with a p-value less than 0.05 in the Chi Square test were considered in Binary logistic regression for estimating the risk for Acne with a 95% confidence interval (C.I.).

RESULTS: Fifty-two percent of participants were found with mild acne, use of yogurt, ice cream butter, margarine, French fries, chocolate, bakery chips, white bread, vegetable, fruits, cake dates, and pickles give a significant association with severity of acne using Fisher's Exact test p<0.05. Logistic regression showed that butter gave more risk for acne with an odds ratio of 1.11 and 95% C.I. (1.0, 9.2). 

CONCLUSION: It can be stated that dairy products, high glycemic index, and fatty foods are associated with acne aggravation in our population. As patients are always concerned about dietary advice, suggesting that they reduce these products would help them maintain their skin.

Measuring area-level disadvantage in Australia: development of a locally sensitive indicator
Authors: Kerr Jessica , Mavoa Suzanne , Schroers Ralf-Dieter , Eagleson Serryn , Exeter Daniel , Watkins Alison , Thornton Lukar
Published: November 2021

Background   In Australia, the Socio-Economic Indexes for Areas (SEIFA), which includes the Index of Relative Socioeconomic Disadvantage (IRSD), captures the socioeconomic characteristics of areas. Because SEIFA rankings are relative to the country or state, the decile categorisations may not reflect an area’s socioeconomic standing relative to areas nearby.

Aims   The aim of the research was to explore whether IRSD rankings could be re-ranked to become locally sensitive.

Data and methods   Using existing SEIFA data to redistribute the membership of current decile IRSD groups, we tested three methods to re-rank all SA1 areas relative to the nearest areas capped at: (1) the nearest 99 neighbours, (2) a population threshold of 50,000 (3) a distance threshold of 10 km.

Results   The reclassification of SEIFA IRSD deciles was largest (up to 8 decile points of change) when comparing the nearest neighbour and population threshold local methods to current state-based rankings. Moreover, compared to using current national and state SEIFA IRSD rankings, the use of local rankings resulted in more evenly distributed deciles between cities, regional, and remote areas.

Conclusions   Because SEIFA IRSD rankings are used to allocate resources and health services, we encourage the combined use of a state and local ranking to refine areas considered the most disadvantaged.
Long term population decline and the impacts of COVID-19 in South Australia’s regions
Authors: Irving Jacob , Horne Sandy , Beer Andrew
Published: November 2021

Background   South Australian regions have been given little attention in discussions on population decline.

Aims   This paper aims to examine the nature and incidence of population decline in South Australia as well as evaluate the potential impacts of COVID-19.

Data and methods   Estimated Resident Population data from 2001 to 2020, and Census data from 2006 and 2016, were used to investigate demographic and economic change. Measures of population change, age structure, employment and components of population change were used.

Results   Population decline has been a feature of South Australia’s regions for decades and continues to be so as more of the population concentrates in its capital and regional centres where greater opportunities of employment and greater provisions of amenities are available. COVID-19 has the potential to accelerate this change if South Australia’s vulnerable regions are not able to absorb the economic impacts the pandemic poses.

Conclusions   A strong driver of population decline in the regions is employment loss in core industries. Strategies that support these industries or otherwise aim to stimulate economic activity in these communities are required to moderate further decline in South Australia’s regions especially as the economy recovers from the impacts of COVID-19.

Published: November 2021

Предложена структурная модель анизотропной среды для расчета напряженнодеформированного состояния в нетронутых массивах горных пород, которая учитывает ряд горнотехнических и горно-геологических факторов. Результаты аналитического решения позволили объяснить известные из практики натурных наблюдений факты (возможность превосходства горизонтальных напряжений над вертикальными, кусочно-линейный характер напряжений и т.д.), которые находились в противоречии с широко распространенными гипотезами о распределении напряжений в породных массивах.

A structural model of an anisotropic medium is proposed for calculating the stressstrain state in intact rock massifs, which takes into account a number of mining and geological factors. The results of the analytical solution allowed us to explain the facts known from the practice of field observations (the possibility of the superiority of horizontal stresses over vertical ones, the piecewise linear nature of stresses, etc.), which were in contradiction with the widespread hypotheses about the distribution of stresses in rock massifs.

The authors solve the problem of diffusion in a parallelepiped-shaped body with boundary conditions of the 1st kind and an internal source of substance, depending on the parallelepiped points coordinates with the fast expansions method. The proposed exact solution in general form contains free parameters, which can be used to obtain many new exact solutions with different properties. An example of constructing an exact solution with a variable internal source depending on one coordinate z is shown in the work. An analysis of the features of diffusion flows in a parallelepiped with the indicated internal source is given. It was found that the concentration of a substance in the center of a parallelepiped is equal to the sum of the arithmetic mean of the concentration of a substance at its vertices and the amplitude of the internal source multiplied by the value

Background: Healthcare-Associated Infections (HAIs) are significant causes of illness and mortality, and nurses are healthcare professionals with the most consistent contact with patients, therefore nurses need to possess adequate knowledge, and awareness. Aim: this study aim to analyze factors impacting nurses' awareness of the prevention of HAIs, such as their knowledge, attitude, and practice compliance. Methods: A systematic review was conducted from the sources of data collection, namely Proquest, Science Direct, Pubmed, and Google Scholar from 2011-2020, with English guidelines used to review the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Results: Data were obtained through a questionnaire survey, direct observation, and self-report from 4329 nurses with a total of 12 inclusion criteria. The result showed that a significant number of nurses do not possess an acceptable level of knowledge and practice, although nurses have a positive attitude. Hand hygiene and the other protective personal equipment need to be used by nurses and other health personal to prevent Urinary Tract Infection, respiratory, and Surgical Site Infection in the hospital.   Conclusion: nurses need to possess the right knowledge, attitude, and guidelines. Standard precaution is important for patient safety management, nurses need to be adequately trained to increase awareness.

BACKGROUND: Osteoarthritis is the main and most common cause of pain and disability in older people. It affects women 3.5 times more than men.

AIM: Therefore, the present study aimed to determine the effect of effleurage massage therapy on symptoms of osteoarthritis in elderly women with osteoarthritis.

MATERIALS AND METHODS: The present study was a cross-sectional clinical trial with a control group on 58 elderly women with mild to moderate osteoarthritis in 2018. At the first stage of the study, we give a massage on each knee every day for 15 min a week by the Effleurage method with standard treatment (100 mg diclofenac) and the control group only received standard treatment. At the second stage, the intervention was shifted in groups according to the study type after 3 weeks of washout. The research instrument was a native questionnaire (The Knee Injury and Osteoarthritis Outcome Score [KOOS]). We analyzed data using the SPSS20.

RESULTS: The research results indicated that knee massage techniques could reduce the severity of symptoms at both stages of the study in the intervention group. At the first stage, the severity of symptoms in Group A (intervention group) significantly decreased after the intervention compared to the pre-intervention and also decreased after washout in Group B (intervention group) after the intervention compared to the pre-intervention (p < 0.0001).

CONCLUSION: Given the effect of massage on reducing symptoms of knee osteoarthritis (morning dryness, stiffness, and swelling,) in elderly women with osteoarthritis, massage therapy is recommended as an effective intervention to reduce symptoms of knee osteoarthritis in these patients.

BACKGROUND: COVID-19 epidemic is changing the lives around the world. COVID-19 is a dangerous and frightening disease so that many people experience anxiety disorders and decreased quality of life.

AIM: The purpose of this study was to analyze the effect of music therapy on the level of anxiety and quality of life of patients infected by COVID-19.

MATERIALS AND METHODS: This type of research is an experimental quantitative study with a randomized controlled trial research design. The sampling technique used in this research is simple random sampling. Data analysis was performed using paired t-test and independent t-test. This study divided the subjects into two groups, namely, the intervention group as many as 51 respondents who received intervention in the form of music therapy with favorite music in the form of religious-themed music, dangdut, pop, and classical music and 51 respondents in the control group who were only given regular intervention. Data collection tool or anxiety questionnaire used Hamilton Anxiety Rating Scale with a reliability of 0.893.

RESULTS: The type of this research was experimental quantitative research using a randomized controlled trial research design. The results showed that after being given music therapy, there was a decrease in anxiety level in the intervention group with an average of 18.7 (mild anxiety) and an average of 33.6 (severe anxiety) in the control group with a significance value of 0.000. In addition, music therapy significantly improved the quality of life with an average of 81.6 (very good quality of life) in the intervention group and an average of 36.7 (poor quality of life) in the control group with a significance value of 0.000.

CONCLUSIONS: Music therapy which was given to COVID-19 patients was proven to reduce anxiety and improve the patient’s quality of life.

Published: November 2021

BACKGROUND: Type 1 diabetes mellitus (T1DM) is a chronic disease in children which is usually caused by autoimmunity that damages pancreatic a and b cells which have functions as blood glucose regulators. Some studies stated that Renalase (RNLS) gene deletion will protect these b cells from autoimmune reactions and Endoplasmic Reticulum (ER) stress. RNLS deletion by genome editing Clustered Regular interspersed Short Palindromic Repeats-CRISPR-related (CRISPR/Cas9) is believed to have the potential to be a therapy for T1DM Patients.

AIM: This research was conducted to know the potential of RNLS deletion using the CRISPR/Cas9 as an effective therapy and whether it has a permanent effect on T1DM patients.

METHODS: The method applied in this research summarized articles by analyzing the titles and abstracts of various predetermined keywords. In this case, the author chose a full-text article published within the past 10 years by prioritizing searches in the last 5 years through PubMed, Google Scholar, Science Direct, Cochrane, American Diabetes Association, and official guidelines from IDAI.

RESULTS: RNLS deletion using CRISPR/Cas9 in mice weakened the response of polyclonal -cell-reactive CD8+ T cells and disrupted the immune recognition to cells so that autoimmune killing did occur. In addition, such deletion prevents RNLS ER stress by increasing the threshold, triggering the unfolded protein response so that ER stress is difficult to occur. RNLS mutations in b cells also increase b cell survivability to oxidative stress.

CONCLUSION: b cells RNLS deletion by genome editing CRISPR/Cas9 is effective in protecting b cells from autoimmune reactions and RE stress. However, further research is needed to determine the side effects and safety of its use.
On Recurrent Neural Network Based Theorem Prover For First Order Minimal Logic
Authors: Baghdasaryan Ashot , Bolibekyan Hovhannes
Published: November 2021

There are three main problems for theorem proving with a standard cut-free system for the first order minimal logic. The first problem is the possibility of looping. Secondly, it might generate proofs which are permutations of each other. Finally, during the proof some choice should be made to decide which rules to apply and where to use them. New systems with history mechanisms were introduced for solving the looping problems of automated theorem provers in the first order minimal logic. In order to solve the rule selection problem, recurrent neural networks are deployed and they are used to determine which formula from the context should be used on further steps. As a result, it yields to the reduction of time during theorem proving.
E - Capacity - Equivocation Region of Wiretap Channel
Authors: Haroutunian Mariam
Published: November 2021

One of the problems of information - theoretic security concerns secure communication over a wiretap channel. The aim in the general wiretap channel model is to maximize the rate of the reliable communication from the source to the legitimate receiver, while keeping the confidential information as secret as possible from the wiretapper (eavesdropper).

We introduce and investigate the E - capacity - equivocation region and the E - secrecy capacity function for the wiretap channel, which are, correspondingly, the generalizations of the capacity - equivocation region and secrecy - capacity studied by Csiszár and Körner (1978). The E - capacity equivocation region is the closure of the set of all achievable rate - reliability and equivocation pairs, where the rate - reliability function represents the optimal dependence of rate on the error probability exponent (reliability). By analogy with the notion of E - capacity, we consider the E - secrecy capacity function that for the given E is the maximum rate at which the message can be transmitted being kept perfectly secret from the wiretapper.
Incremental autoencoders for text streams clustering in social networks

Published: November 2021

Clustering data streams in order to detect trending topic on social networks is a chal- lenging task that interests the researchers in the big data field. In fact, analyzing such data needs several requirements to be addressed due to their large amount and evolving nature. For this purpose, we propose, in this paper, a new evolving clustering method which can take into account the incremental nature of the data and meet with its principal requirements. Our method explores a deep learning technique to learn incrementally from unlabelled examples generated at high speed which need to be clustered instantly. To evaluate the performance of our method, we have conducted several experiments using the Sanders, HCR and Terr-Attacks datasets.
