Published: March 2021

Individuals often encounter psychological distress after a diagnosis of cancer, especially head and neck cancer (HNC). Worries regarding restricted functions, facial disfigurement, waiting time for investigation and duration of hospital stay for treatment make them feel awful. Often this feeling goes unnoticed and is underestimated. We aimed to assess the prevalence of the dreadful feeling in terms of anxiety and depression in newly diagnosed head and neck cancer patients. A cross-sectional study was conducted in two cancer-treating institutions in South India. About 357 freshly diagnosed HNC patients participated in the study. Pre-validated Hospital Anxiety and Depression Scale (HADS) was used to assess the anxiety and depression levels. Descriptive statistics was done to report socio-demographic, clinical variables and mean scores. Independent t-test and correlation test were done for comparison and association, respectively. Mean depression score for males and females was 11.481, 11.865, respectively. Mean anxiety score for males was 11.708 and 11.792 for females. There was a strong positive correlation between depression and anxiety score (0.864) among patients. There was no statistically significant difference in the mean anxiety and depression scores among gender, socioeconomic status, marital status and cancer stages (p>0.05). Newly diagnosed HNC patients had an abnormal level of anxiety and depression, which needs special attention and care during treatment for a better outcome.

Dentists are one among the medical professionals who often encounter complex ethical issues. Playing the role of a health professional, business enterpriser and academician they often run into specific and conflicting ethical demands in practice and research. This cross-sectional study was conducted among dental professionals attached to educational institutions and private practitioners. A total of 95 participants, including private practitioners, faculty members, and post-graduate students, were recruited. A pre-validated, questionnaire containing questions related to awareness and perception in dental ethics was administered. Descriptive statistics was done to report the level of awareness and perception of dental professionals. About 65% of post-graduate professionals had awareness in clinical ethics when compared to undergraduate professionals who had 58% awareness. However, 75% of undergraduate professionals had awareness in research ethics compared to post-graduate professionals with 70% awareness. There was no difference in the perception level among graduate and post-graduate professionals. The awareness of dental ethics varied among dental professionals. There is a need to introduce specific continuing dental educational (CDE) programs to promote knowledge on dental ethics and dental jurisprudence to save dentist and their patients from encountering uneventful situations.

Published: March 2021

Soil-transmitted helminth (STH) infections occurs via fecal-oral route. WHO has reported there are up to 90% of children from poor communities with inadequate hygiene and sanitation prone to at least one STH infection. In Malaysia, the indigenous community (Orang Asli) is the predominant communities prone to STH infections. Hence, this study was aimed to determine the prevalence of STHs infections among Orang Asli in Kampong Donglai Baru, Semenyih, Selangor. Questionnaires surveys were conducted to gather information on the risk factor associated with the Orang Asli community following with stool samples were collected from the villagers. Basic parasitology method, floatation technique was carried out to determine the type and burden of STHs. Total sample obtained from salt-sugar floatation method were sixty seven (n=67), with 64 (95.5%) were positive for STH infection. The prevalence of Trichuris trichiura was 85.9% (n=55) while Ascaris lumbricoides was 93.8% (n=60). Results shown majority of the villagers have double infection (79.7%, n=51). Several risk factors were found significantly associated (p<0.05) with T. trichiura infection such as age factors, education level and frequency of hand washing. However, those risk factors were no significant associated with A. lumbricoides  infection. The study showed a higher prevalence rate of STH infection predominantly by Trichuris trichiura and Ascaris lumbricoides within a small group of the Orang Asli community, hence further prevention method like administration of anthihelminthic drug is recommended.

Reasons for choosing parenteral nutrition (PN) products depend on healthcare institutions internal and external factors. A decision to start, continue, scale-up, scale down, or stop compounding of PN involves multiple stakeholders. This study is an effort to analyze such factors and recommendations on decision-making. A strength, weakness, opportunities, threats (SWOT) analysis was prepared in consultation with major PN providers in the UAE and comparing to international best practices. Based on the SWOT analysis, a set of recommendations was prepared using the GRADE system (classification of quality of evidence and strength of recommendation). Feedback on the SWOT analysis and recommendations were collected from the PN providers. The SWOT analysis and recommendations address aspects of the choice of MCB-PN or compounded PN. It includes considerations on PN indication, availability of ingredients, types of patients, safety, and cost management with labor, automation, and outsourcing. It was received well. The SWOT analysis and recommendations are useful in decision-making in complex therapy like PN. It helps in institutional decisions on choices of MCB-PN or compounded PN. The impact of the recommendations is to be measured in the future.

Skin diseases are commonly observed due to altered lifestyle, lack of physical exercise, poor hygiene, mental stress and improper food habits. Kushta  (Skin diseases) is divided into Maha Kushta  (Major skin diseases) and Kshudra Kushta (Minor skin disease). Kitibha Kushta  (Plaque Psoriasis) is included in Kshudra Kushta  commonly found today, having sign and symptoms similar to Plaque psoriasis. Due to relapsing nature of Plaque psoriasis it needs long duration treatment. Ayurveda provides long lasting results by treating the disease and preventing reoccurrence. In this case study, a 43 years old male came to OPD of Kayachikitsa with chief complaint of Kandu  (Itching), dry silvery white patches over left leg treated with Shodhana Chikitsa  (Body purification treatment) using Vaman Karma  (Therapeutic Emesis) and Shaman Chikitsa (Alleviating treatment) using internally Gandhaka Rasayana, Panchatikta Ghrita and S-kin powder, Shabsoria Oil for external application for 1 month. The PASI score was 14.4. Before treatment, after 15 days it was 7.4 and after 30 days it was reduced to 0. Patient got relief in the symptoms.

Parthenolide Induces Oxidative Stress and Impedes Cell Migration by Suppressing Wnt Pathway and Epithelial-Mesenchymal-Transition (EMT) in HCT-116 Metastatic Colorectal Cancer Cells
Authors: Sananda Dey  , Nensina Murmu  , Mijanur R Molla  , Sandeep K Dash  , Biplab Giri
Published: March 2021

Colorectal cancer (CRC) is a vital cause of cancer morbidity and mortality. 50% of CRC patients suffer from an aggressive metastatic disease which ultimately fallout in death. In metastatic cancer, tumour cells migrate, invade, and finally colonise to the distant organ by degrading their attachments with the extracellular matrix. Parthenolide (PTL) is a secondary metabolite of feverfew (Tanacetum parthenium) plant. It shows its cytotoxic effect towards cancer cells via different cellular signalling pathways like inhibition of NF-κB, STAT3, MAPK, JNK pathways, activation of p53 etc. In the present study, we have assessed anti-cancer and anti-metastatic potential of PTL against human HCT-116 metastatic colorectal cancer cells. Analysis of cellular oxidative status (GSH/GSSG) of PTL treated HCT-116 cells showed a significant decrease (p<0.05) in GSH level while GSSG level was increased significantly (p<0.05) on PTL treatment. PTL also increased the amount of intracellular reactive oxygen species. The qRT-PCR analysis revealed that PTL down-regulates c-fos, c-jun and N-cadherin expression and up-regulates E-cadherin expression indicating inhibition of cell migration and metastasis by EMT pathway. PTL inhibited the MMP-9 expression in a dose-dependent fashion and inhibited cancer cell migration by regulating Wnt/β-catenin signalling through the up-regulation of DKK-1 protein expression indicating PTL has a promising anti-cancer potential against HCT-116 metastatic colorectal carcinoma cells.

Published: March 2021

Представлена новая схема получения чистого спинового состояния для однодетерминантной волновой функции, построенной на орбиталях Хартри—Фока или Кона—Шэма. В основе лежит разложение неограниченного детерминанта по ограниченным детерминантам, построенным в базисе парных орбиталей. Проектирование позволяет выделить компоненты спиновой плотности, соответствующие чистым спиновым состояниям, и оценить вес спиновых контаминантов в спиновой плотности. Эффективность нового подхода продемонстрирована на примере реакции окисления метана. Показано, что самосогласованные решения уравнений Хартри—Фока или Кона—Шэма с нарушенной спиновой симметрией (broken spin symmetry) — это не артефакт однодетерминантного приближения, уравнения отражают реальную спиновую поляризацию, приводящую к появлению отрицательной спиновой плотности в некоторых частях молекулярной системы.
Структура ближнего окружения ионов в водных растворах хлорида цинка по данным рентгеноструктурного анализа
Authors: Смирнов П.Р. , Гречин О.В.
Published: March 2021

Методом РСА определены количественные характеристики ближнего окружения ионов в водных растворах ZnСl2 в широком диапазоне концентраций. В насыщенном растворе ион Zn2+ координирует две молекулы воды на расстоянии 0.208 нм. Ионами сформирован ионный ассоциат, содержащий один ион Cl– на расстоянии 0.225 нм и два иона Cl– на расстоянии 0.380 нм. При уменьшении концентрации из ассоциата выходят ионы Cl– — сначала находящиеся на более дальнем расстоянии, а затем входящий в состав контактной ионной пары. В результате при разбавлении раствора ионные пары распадаются, и ионы Zn2+ и Cl– переходят к независимой гидратации. Количество молекул воды в координационной сфере иона Zn2+ возрастает до шести на расстоянии 0.212 нм. С разбавлением закономерно увеличивается количество молекул воды в гидратной сфере аниона на среднем расстоянии 0.312 нм и во второй координационной сфере катиона на среднем расстоянии 0.424 нм.

PENGARUH RETAKAN PERMUKAAN TANAH TERHADAP STABILITAS LERENG BUKIT GUNTUR MACAN, GUNUNG SARI. LOMBOK BARAT
Authors: Muchtaranda Ismail H , Sulistyowati Tri
Published: March 2021

Peristiwa  longsor sering terjadi pada saat hujan lebat atau sesaat setelah hujan reda. Hal ini dikarenakan air hujan berinfiltrasi ke dalam tanah, sehingga tanah menjadi jenuh,  tekanan air pori di dalam tanah meningkat dan mengurangi kekuatan tanah, akibatnya terjadi peristiwa longsor. Salah satu penyebab air hujan cepat berinfiltrasi ke dalam tanah adalah adanya retakan (crack) pada permukaan tanah, baik pada permukaan tanah datar maupun pada bagian yang miring dari suatu lereng. Retakan dapat terjadi karena sifat kembang susut tanah, kegiatan pembangunan oleh manusia, penurunan tanah tidak seragam dan masih banyak penyebab lainnya. Dalam penelitian ini dilakukan pemodelan lereng dengan retakan pada permukaan puncak lereng yaitu jarak dan kedalaman retakan. Selanjutnya air pada retakan yang berasal dari air hujan ataupun air dari rumahâ€“rumah penduduk dapat menimbulkan rembesan dan akan terinfiltrasi. Analisa stabilitas lereng, analisa infiltrasi dan rembesan dilakukan dengan menggunakan metode elemen hingga. Hasil analisis yang diperoleh adalah angka keamanan dari lereng terhadap letak dan kedalaman retakan tanah. Hasil analisis menunjukkan bahwa retakan yang terisi oleh air akibat hujan atau tanpa hujan, angka keamanan berkurang dibandingkan dengan tanpa retakan. Demikian pula jarak retakan semakin dekat dengan bidang longsor, angka keamanan semakin menurun. Angka keamanan juga semakin menurun seiring dengan semakin dalam retakan. Kedalaman retakan memberi jalan air yang lebih cepat meresap ke dalam tanah sehingga mendekati bidang longsor, demikian pula jarak retakan. Nilai SF kondisi awal lereng = 0,785, dengan adanya retakan nilai SF =0,777, jika ada pengaruh aliran transient yang berasal dari hujan SF = 0,754 dan pada kondisi aliran tetap (steady) SF = 0,715
Short Hebrew International Physical Activity Questionnaire: Reliability and Validity
Authors: WEISSBLUETH EYAL
Published: March 2021

Background: The International Physical Activity Questionnaire (IPAQ) aims to measure physical activity consistency throughout the world. It has been translated into many languages and its validity has been examined worldwide. However, the IPAQ has not been translated into Hebrew and the psychometric properties of the Hebrew version have yet to be evaluated. Material/Methods: The current study assessed the test-retest reliability of the short IPAQ in Hebrew (IPAQ-S-H) and its validity among college students. Intra-class correlation coefficients were computed to assess reliability, and survey responses were compared to VO2max to determine concurrent validity. Results: The IPAQ-S-H’s test-retest reliability was primarily high, particularly for total physical activity (ICC = 0.90; 95%CI = 0.87-0.93). While agreement for the physical activity components of the survey was higher (ICCs: 0.58-0.79), agreement for sitting time was lower (ICC = 0.39; 95% =0.25-0.52). When comparing the survey scores to VO2max, total physical activity and vigorous intensity activity were significantly correlated with maximal oxygen uptake (Pearson’s r = 0.43 and 0.40, respectively), but not with other survey components. Conclusions: The IPAQ-S-H primarily exhibits moderate reliability and validity, which are comparable psychometric properties to other IPAQ validation studies. Further validation is warranted among more representative samples utilizing objective monitoring to determine criterion validity.
The construction and empirical verification of the Sense of Team Efficacy Questionnaire (Kwestionariusz Poczucia Druzynowej Skutecznosci)
Authors: WALACH-BISTA ZUZANNA
Published: March 2021

Background: This article presents the procedure of the elaboration and verification of the first Polish Sense of Team Efficacy Questionnaire (Kwestionariusz Poczucia Druzynowej Skutecznosci – KPDS). Material/Methods: Two research stages involved a total of 373 professional athletes. Based on the collected data, the internal structure and psychometric properties of the instrument were established. Results: As a result of the conducted statistical analyses, a questionnaire was obtained. Analyses confirmed the stability of the internal structure of the questionnaire. The instrument also obtained satisfactory coefficients of reliability (using Cronbach’s alpha internal reliability coefficient) and construct validity. In order to establish the convergent and discriminant validity of the KPDS, the analysis of the multitrait-multimethod matrix was applied, using the Group Environment Questionnaire (GEQ). Predictive validity was established using the result obtained in a match played directly after the conducted study. Conclusions: The obtained results confirmed the relevance of creating the KPDS. The questionnaire was made up of 21 items representing 4 subscales: fitness, preparation, effort and endurance. Calculation of a general score for the KPDS also proved to be possible.

Background: Regression of body balance function is one of the main risk factors in falls among the elderly. The aim of this article was to evaluate changes in static and dynamic body balance levels among people over 65 years under the influence of Nordic Walking training. Material/Methods: The research was conducted with participation of 21 people over 65 years old. The training lasted throughout a period of 6 months. Frequency of exercises was twice a week. Evaluation was conducted using 8-Foot Up-and-Go from the Senior Fitness Test and a single leg balance test from the EUROFIT test for adults. Results: A general tendency for body balance improvement was observed among the elderly under the influence of Nordic Walking training. The average test results for static body balance level were improved by 4.32%. In the case of dynamic body balance the increase was 5.68%. Conclusions: Loss of body balance is a problem affecting almost 14% of the population between 50-60 years of age. In the subsequent decade of life the risk of a fall increases to 22% on average, and among octogenarians the problem concerns over 33% of them. The research described below shows that using Nordic Walking training is advisable as a preventive measure against further diminishing of dynamic and static body balance among the elderly.

Background: This study aimed to examine the associations between individual, social and environmental characteristics and out-of-school television viewing, computer use, and overall time spent in sedentary behaviors. Material/Methods: A sample of 11-year-old children (N = 155) in Finland wore an accelerometer (Actigraph GT3X) for seven days. Before the accelerometer-use, questionnaire assessments of television viewing, computer use, reported PA, bedtimes, wake-up times, perceived parental PA and PA encouragement and measurements of weight and height were obtained. Weather data were obtained for the 7 days of accelerometer use and parents reported their educational background. Associations between the studied correlates and average minutes of out-of-school television viewing, computer use, and overall time spent in sedentary behaviors were tested using multiple linear regression analyses. Results: Television viewing, computer use, and overall time in sedentary behaviors primarily had separate individual and social correlates. Only recorded and reported PA were associated with all the outcomes. Of the physical environmental correlates, colder after school temperatures and less hours of daylight were associated with increased overall time in sedentary behaviors. Conclusions: Preventive interventions and studies should take into account the separate correlates of television viewing, computer use, and overall time in sedentary behaviors.

Background: Little research providing reliable information on the popularity of sauna among university students has been found in Polish and foreign literature. The aim of the study was to assess the influence of socioeconomic and psychological factors on the popularity of sauna among female university students. It was also examined whether sauna use exerted any influence on the students’ well-being. Material/Methods: The research was conducted in 2012 with 550 first-year female students, aged 19-20. The research was carried out with a diagnostic survey method using an anonymous questionnaire. Results: Our findings revealed that the applied socioeconomic factors (permanent place of residence, parents’ educational background and the students’ monthly budget) as well as psychological factors (the evaluation of the sauna during bathing and the following day) significantly affected the frequency of sauna use. The research revealed a significant and positive influence of the sauna use on the students’ well-being (during bathing and the following day). Conclusions: Sauna exerts a positive influence on students’ mental well-being and should be used as a calming and relaxing method which could be implemented in the physical activity as well as health programs. Despite the statistically significant differences, the effects of the factors under investigation were analyzed only within a partial range due to a relatively low level of interest among the students in taking sauna bathing.
The effect of front and back squat techniques on peak loads experienced by the Achilles tendon

Published: March 2021

Background: A primary technique in the discipline of strength and conditioning the squat has two principal ‘back and front’ variants. Despite the physiological and strength benefits of the squat, the propensity for musculoskeletal injury is high. The current investigation examined the influence of the front and back squat variations on the load experienced by the Achilles tendon. Material/Methods: Achilles tendon loads were obtained from eighteen experienced male participants as they completed both back and front squats. Differences between squat conditions were examined using Bonferroni adjusted (p = 0.0125) paired t-tests. Results: The results showed that the peak Achilles tendon load was significantly greater in the back squat (2.67 ±0.74 B.W) condition compared to the front squat (2.37 ±0.69 B.W). Conclusions: Given the proposed relationship between the magnitude of the load experienced by the Achilles tendon and tendon pathology, the back squat appears to place lifters at greater risk from Achilles tendon injury. Therefore, it may be prudent for lifters who are predisposed to Achilles tendon pathology to utilize the front squat in their training.

Background: The aim of the present study was to assess physiological-biochemical reactions to incremental exercise loads and the levels and development of endurance skills in young male and female team game players. Material/Methods: The study sample comprised 370 soccer, handball, basketball and volleyball players (186 girls and 184 boys) from the Lower Silesian Regional Teams in Poland, aged 14.20 ±1.37 years (boys) and 13.90 ±1.15 years (girls). The exercise test consisted ofthe shuttle run Beep Test for estimation of aerobic fitness. The assessment of endurance skills was based on the length of the covered distance in the Beep Test as well as on measurements of the heart rate (physiological) and blood lactate concentration (metabolic). Results: Among the four studied groups of players a statistically significant improvement in endurance skills was noted in male volleyball players (p ≤ 0.05). Conclusions: Significantly higher levels of endurance skills in young male handball, basketball and volleyball players and in female volleyball players who remained on the regional teams for two consecutive years may be an indication of the players’ proper selection and training. Significant changes in blood lactate concentration in young players, revealed in both cross-sectional and continuous studies, were only noted in male volleyball players. Significant decreases in the heart rate in the cross-sectional study was found only in male handball and basketball players and in female basketball players, whereas in the continuous study only in male handball players. An assessment of young players’ physiological-biochemical reactions on the basis of exercise test results can effectively enhance the optimization of training loads.
Physical activity and body image of women: literature review
Authors: MOSUR-KALUZA SONIA , GUSZKOWSKA MONIKA
Published: March 2021

Background: This study represents a review of literature on the relationship between recreational physical activity and the body image. Material/Methods: This research encompasses 39 papers published between 2008 and 2015 that were available in the Academic Search Complete database. Results: The results of comparative, prospective, and experimental research are ambiguous. These data suggest both a positive relationship between the body image and physical activity, i.e. a more positive body image among more active people and an improvement in the body image as a result of regular exercise, and a negative relationship, in particular, a more negative body image in persons engaging in “aesthetic” sports. Conclusions: Apparently, this is determined by the type of physical activity, i.e. recreational vs. sport. In the case of the latter, it is determined by the sport discipline chosen by respondents.
