Authors: Raj shivaani M R  , Preetha Selva  
Published: May 2020

Antibiotics happen to be the most commonly used medicines, especially in developing countries like India, where infectious diseases are at a raise. Millions of antibiotics are prescribed by physicians all over India. The main objective of the present study is to analyze the prescription pattern of the antibiotics given to the in-patients of our hospital and to access the rationality of these prescriptions given, using the World Health Organization's core drug prescribing indicators. A total of 400 in- patients from Departments of Pediatrics, General Surgery, Obstetrics & Gynecology and Orthopedics were analyzed after screening for inclusion and exclusion criteria. The numbers of females are 248 (62%) and the males are 152 (38%) in a ratio of 1:1.63. 101 patients belonged to 40-60 years age group. The pattern of antibiotic usage in the Department of Pediatrics, Obstetrics and Gynecology, General Surgery, Orthopedics was studied. The most common antibiotics prescribed were Cefotaxime (44%), Amoxicillin(38%) and Cefazolin (38%, 24%) in Departments of Pediatrics, Obstetrics & Gynecology, Surgery and Orthopedics respectively. The total numbers of drugs prescribed were 1441 out of which 612 were antibiotics (43.09%). The number of antibiotics per prescription was 1.53. The average number of drugs prescribed per prescription was 3.6. The percentage of encounters with injections was 26.48%. The percentage of drugs prescribed by generic name is 36.2%. The percentage of drugs from the Essential Drug List was 92%. The percentage of fixed-dose combinations of antibiotics prescribed was 14.54%. Hence, in our study, though most of the drugs are given from the Essential List of Medicines, drugs given by a generic name is low. Physicians can be encouraged to prescribe more drugs by generic name. To conclude, antibiotic stewardship interventions have to be implemented to promote the judicious use of antibiotics to prevent adverse consequences.

Published: May 2020

Researchers had found that there is an association between oxidative stress and osteoporosis. Postmenopausal osteoporosis causes major public health problems. Since Uric acid has strong antioxidant properties, it will improve bone quality. This cross-sectional observational study was done to determine the association of Uric Acid and Bone Mineral Density of 75 healthy postmenopausal women who came for a master health checkup. The mean age was 60.5 years. After ethical clearance and informed consent, women were recruited for the study at Saveetha Medical Hospital Chennai. Women with medical conditions or who were using drugs affecting bone metabolism or uric acid were excluded. Basic investigations were Hb, serum UA, blood urea, serum creatinine, serum calcium and alkaline phosphatase, blood glucose and glycosylated Hb. Total Cholesterol, HDL, LDL, VLDL, 25 hydroxy Vitamin D were also done. Serum UA levels were graded as <3.9, 3.9–4.9, 5–6.1, and ≥6.2  mg/dl. Bone Mineral Density (BMD) was calculated with Dual Energy X-ray Absorptiometer (DXA). Osteoporosis was defined as BMD T-score −2.5 and below. BMD with a T-score of -1  −2.5 was classified as osteopenia (WHO). In women with high UA, there were significantly higher levels of low-density lipoprotein, and calcium, as compared to women with low UA group (p<0.05). High UA group, as compared to the low UA group, also had lower levels of high-density lipoprotein (p<0.001). Women with higher Uric acid levels had lower BMI, lesser years of duration of Menopause and increased BMD. Serum UA level had a positive correlation with the Lumbar BMD T score and Right Femoral Neck BMD T Score. In UA >5.4mg/dl group Osteoporosis was nil.

It was noted that from 2011 to 2017 rice production in Indonesia had increased by 23.77%. Perusahaan X is a rice supplier company in Bandung city with the transfer of rice carried out by porters (kuli panggul) manually without tools. Porters do the lifting process with a duration of 9 hours and the load carried weights from 10 kg to 50 kg. Repetitive and monotonous task can increase stress levels and fatigue at work. Improvement of work condition is needed through the measurement of stress and fatigue level on the porters of rice in Perusahaan X using cocorometer and The Subjective Self Rating Test (SSRT) questionnaire to increase productivity in the company. Ten men as respondent with ages ranging from 20-41 years with work experience of 1-6 years were tested. The result shows that respondents before work (α/2table< α/2calculated< α/2tableor 0.025 < 0.544 < 0.975) and after work (α/2table< α/2calculated< α/2tableor 0.025 < 0.413 < 0.975) experienced increased stress and fatigue level. The correlation between stress and fatigue level before work (degree of freedom = -0.219) and after work (degree of freedom = -0.292) shows low correlation. Stress level is not only influenced by fatigue level but also influenced by the age and work experience of respondents during work. Perusaahaan X should do several things to reduce the increased in stress and fatigue by creating a pleasant atmosphere at work; requiring the workers to do stretching at rest break; providing bonus; and providing drinking water so that respondents are not dehydrated.

ABSTRAKReactor Cavity Cooling System (RCCS) adalah salah satu sistem keselamatan pada Reaktor Daya Non Komersial (RDNK). Untuk mensimulasikan keadaaan tersebut, dibuat prototype Heater Element System (HES) yang merupakan sistem pemanas listrik dan berfungsi untuk memberikan kalor pada simulator dinding RPV (wall) seperti pada acuan RPV tipe HTGR. Tujuan penelitian adalah untuk memperoleh karakteristik temperatur selama pemanasan prototype HES hingga mencapai temperature 400°C berdasarkan posisi vertikal dan horizontal HES. Metode pengamatan dilakukan dengan menggunakan kamera infra merah NEC tipe TH9100ML sebagai alat ukur temperatur dan alat visualisasi ditribusi temperatur. Hasil pengamatan menunjukkan, bahwa kehilangan kalor pada prototipe HES pada posisi vertikal lebih kecil dibandingankan pada posisi horizontal hal ini disebabkan karena luas permukaan pada posisi horizontal sebesar 7,260 cm2 lebih memungkinkan untuk kehilangan kalor lebih besar. Posisi vertikal temperatur yang dicapai pada wall prototipe HES lebih tinggi dibandingkan pada posisi horizontal.Kata Kunci: RCCS, Heater Element System, kamera infra merah, temperatur ABSTRACTReactor Cavity Cooling System (RCCS) is one of the safety systems in Non-Commercial Power Reactors (RDNK). To simulate this situation, a prototype Heater Element System (HES) was made using electric heating system as a heat sources and it serves to provide radiation heat to the RPV wall simulator as the reference of the RPV of HTGR type. The purpose of this study was to obtain the temperature characteristics during the heating of the HES prototype to reach temperatures of 400°C base on HES position, horizontal and vertical positions. The observation method was carried out using a TH9100ML infrared camera NEC type as a temperature measurement and a temperature distribution base on visualization. The observations show that the heat loss in the HES prototype in the vertical position is smaller than in the horizontal position because this is because the surface area in the horizontal position 7.260 cm2 is more likely to lose more heat. The vertical position the temperature achieved on the HES prototype wall is higher than in the horizontal position.Keywords: RCCS, Heater Element System, infrared camera, temperature

Spór o medyczną klauzulę sumienia a konstytucyjne zasady równości i bezstronności światopoglądowej władz publicznych
Authors: Pawlikowski Jakub 
Published: May 2020

W artykule przeanalizowano problem sprzeciwu sumienia z perspektywy konstytucyjnej zasady równości (art. 32 Konstytucji RP) oraz bezstronności światopoglądowej władz publicznych (art. 25 ust. 2). Zasady te zakazują prawodawcy i władzom publicznym wprowadzania nieuzasadnionych nierówności w stosunkach prawnych w sferze publicznej, szczególnie w zakresie podstawowych praw i wolności. Zakazują także arbitralnego opowiadania się po jednej ze stron sporów światopoglądowych, aby uprzywilejowując jedną ze stron nie ograniczać nieproporcjonalnie fundamentalnych praw innych stron. W obszarze świadczeń zdrowotnych konieczność ochrony zdrowia lub życia pacjentów uzasadnia ich uprzywilejowanie w dostępie do świadczeń zdrowotnych oraz nałożenie odpowiednich obowiązków i ograniczeń prawnych w zakresie wolności sumienia na osoby wykonujące zawody medyczne. Jednak większość przypadków manifestowania sprzeciwu sumienia w praktyce medycznej nie dotyczy sytuacji zagrożenia zdrowia lub życia świadczeniobiorców. Co więcej, wynika z woli respektowania zasady poszanowania życia każdej istoty ludzkiej ze strony obdżektora. Spory wokół kwestii ochrony życia poczętego, do których często nawiązuje się w kontekście dyskusji wokół klauzuli sumienia, mają bez wątpienia podłoże światopoglądowe. Jednak nawet zakładając niemożność ich rozstrzygnięcia, nie ma podstaw, aby władze publiczne, w sytuacjach, w których nie występuje konieczność ochrony życia i zdrowia ludzkiego, opowiadały się po stronie poglądu akceptującego naruszanie ludzkiego życia ograniczając jednocześnie wolność postępowania w zgodzie z sumieniem osób przyjmujących pogląd przeciwny. Zatem w przypadkach wykraczających poza konieczność ochrony zdrowia i życia prawodawca nie powinien arbitralnie ograniczać wolności sumienia świadczeniodawców. W przeciwnym przypadku narusza zasadę równości wobec prawa w zakresie podstawowych praw i wolności oraz tworzy ramy prawne dla dyskryminacji niektórych świadczeniodawców ze względu na ich zawód, funkcję lub światopogląd. Niezgodne z zasadą równości byłoby także różnicowanie uprawnień w zakresie sprzeciwu sumienia pomiędzy różnymi grupami osób zaangażowanych w opiekę nad pacjentem.

Published: May 2020

Background: The effect of combined repetitive transcranial magnetic stimulation (rTMS) and scalp acupuncture stimulation (SAS) on middle cerebral artery occlusion (MCAO) mice has not yet been reported. The regulation of gene expression after combined stimulation remains unclear. Objective: To analyze gene expression patterns through ribonucleic acid (RNA) sequencing. Methods: Thirty-six 8-weeks-old C57BL/6J male mice weighing 50–60 grams were used for this experiment. The MCAO was induced with 60-min occlusion and subsequent reperfusion of the middle cerebral artery. Experimental mice were randomly assigned to four groups, with nine mice in each group, as follows: control group (no treatment), SAS group (10 minutes SAS), rTMS group (1 Hz rTMS), and combined group (1 Hz rTMS and SAS). Stimulation was performed from the 3rd day to the 7th day after the induction of MCAO. All mice were sacrificed, and brain tissues were taken from the motor area of the MCAO lesion. We analyzed their gene expression profiles using RNA sequencing technology. Results: After stimulation, the grip strength increased in the SAS and rTMS group compared to the control and combined group. The nuclear factor kappa-light-chain-enhancer of activated B cells (NF κB) was the key up-regulated protein in the SAS group while src homologus and collagene gene (SHC) and p90 ribosomal protein S6 kinases (p90RSK) were key up-regulated proteins in the rTMS group. However, the C-terminal src kinase-homologous kinase (CHK) was down-regulated whereas p90RSK was up-regulated in the combined group based on the RNA sequencing analysis. Conclusions: Each stimulation method showed different patterns with neurotrophin signaling pathway including NF κB, SHC, p90RSK, and CHK. These can be used in further mechanistic studies about gene expression related to neurorecovery.
