Published: February 2022

Health is one of the factors that make progress in an area. Handling a health problem in the form of basic health services in each area, as implemented in the Tanggaran village, is one of the village government's actualizations and responsibilities to deal with health problems, such as stunting and sanitation. This study focuses on examining basic health services in Tanggaran Village, Trenggalek Regency. Researchers used the PRA (participatory rural appraisal) method. Besides, data was obtained from a survey on community-related to basic health services with approximately 242 respondents from 3 hamlets. The survey results prove that there are still people in the Tanggaran village who have basic health services problems. The problems that occur do not only come from the village government, but people who are less aware of the importance of a healthy environment. For example, public access to information on health insurance is still limited at health service locations, minimal public service complaints, and community participation in a clean and healthy environment is still low.(Kesehatan termasuk salah satu faktor yang menjadikan kemajuan di suatu daerah. Penanganan terhadap suatu masalah kesehatan berbentuk pelayanan kesehatan dasar pada setiap daerah, seperti yang terlaksana pada Desa Tanggaran merupakan salah satu aktualisasi dan tanggung jawab pemerintah desa untuk menangani masalah kesehatan, seperti stunting dan sanitasi. Penelitian ini berfokus mengkaji tentang pelayanan kesehatan dasar di Desa Tanggaran, Kabupaten Trenggalek. Peneliti menggunakan metode PRA (participatory rural appraisal) atau pemahaman partisipasi kondisi pedesaan. Selain itu data diperoleh dari hasil survei pada layanan kesehatan dasar masyarakat dengan kurang lebih 242 responden dari 3 dusun yang dijadikan fokus. Dari hasil survei membuktikan bahwa masih ada warga masyarakat di Desa Tanggaran yang memiliki masalah layanan kesehatan dasar. Masalah yang terjadi tersebut tidak hanya berasal dari pemerintah desa, akan tetapi masyarakat yang kurang menyadari tentang pentingnya lingkungan sehat. Seperti, akses masyarakat terhadap informasi jaminan kesehatan masih terbatas di lokasi layanan kesehatan, minimnya pengaduan pelayanan publik, dan partisipasi masyarakat terhadap lingkungan hidup bersih dan sehat masih rendah).

Authors: Kaur Japleen , Sharma Shruti , Singh Manik Inder , Sharma Sarit
Published: February 2022

Medical and nursing students may have to face healthcare-related violence, especially now as they may be doing clinical duty during the Covid-19 pandemic. This study was conducted to analyse the perceptions and attitudes of medical and nursing students towards violence against healthcare workers (HCWs), when presented with audio-visual depiction of simulated scenarios. This cross-sectional study was conducted over a period of six months (April to September 2019) among the undergraduate medical and nursing students of first, second, pre-final and final years making it a total of 800 students. Video clips were shown to the students pertaining to HCWs’ interactions with patients and relatives, and their responses were noted. Among 615 participants who completed the proforma, 248 (40%) students reported having observed or experienced violence in their clinical postings. Overall, 70.7% of medical and 68.5% of nursing students said that they would report incidents of violence to the authority. The questionnaire based on video-based simulated scenarios brought forth the perception that in triggering an act of violence, both the healthcare worker and the attendant could be at fault and full disclosure of complications was a necessary step in preventing such an act of violence. Sensitisation about the same should be incorporated into the teaching curriculum by using simulated scenarios to prepare them to manage such incidents.
ROAD TRAFFIC SAFETY: A CASE STUDY OF THE PILA POVIAT IN POLAND
Authors: GORZELANCZYK Piotr , HUK Aleksander
Published: February 2022

Every year, many road accidents occur on Polish roads, in which many people lose their lives and health. Therefore, an attempt was made to analyze road accidents in the Piła poviat. The source of the analysis were the authors' observations and statistical data. This study was conducted on a sample of 250 inhabitants. Hence, a questionnaire was used. Most people, more than half, about 56%, travel by car because it is a more convenient and faster means of transport. While 35% of respondents stated that they feel relatively safe on the roads. A majority, 65%, of the respondents did not participate in a road accident. Further, 60% of the respondents replied that there were many accidents in the Piła poviat, and only 11% answered that there were not many accidents. According to the respondents, the biggest cause of the accidents is alcohol, inattention of drivers and haste. Despite the information, advertisements, scale of these accidents, and opinions of family and friends, people still drive under the influence of alcohol. Year by year, the number of accidents on the roads of the Piła poviat is low, but still considerably high. There is no best way to stop this from happening. In Piła itself, circular intersections have been introduced to improve safety, such an operation is one of the methods for smoother traffic. Additionally, in residential areas, there are more speed bumps to reduce the speed of vehicles. The conclusions obtained in this article can be successfully implemented, not only in other cities in Poland but also in Europe as well.
SELECTED PROBLEMS OF RISK EVALUATION OF CHANGE IN CERTIFIED CIVIL AVIATION ORGANISATIONS
Authors: MARKIEWICZ Telesfor Marek , MAKOWSKI Piotr
Published: February 2022

This article presents some of the generalised results of this research conducted in the form of a diagnostic survey among Safety Managers and a review of safety risk management procedures, including the rules of change risk evaluation, applied in selected civil aviation organisations subject to the survey. This publication aimed to put them under the discussion of experts interested in the issues. Important problems resulting from the necessity to meet general guidelines standardising processes of risk management, formulated in international law regulations [2], as well as in advisory materials of the International Civil Aviation Organisation [6-8], and others [3, 4], including national ones [11], in confrontation with the need for their practical application, were described. Concerning the general rule of risk evaluation described there, inconsistencies in interpretation of the scale of probability and frequency indices and their influence on the evaluation context were pointed out. A model, considering the time aspect in Event Tree Analysis - ETA procedures based on [5, 9], was proposed. Perceived threats to the results of change risk evaluation caused by applying the "the worst foreseeable situation" principle were described. A different approach in the evaluation of change risk based on a comprehensive assessment of the impact of all identified risks on the defined effect was also proposed. Proposals were made to eliminate the disadvantage resulting from the definition of the probability index value – "extremely improbate".

The data search was carried out qualitatively with the case study method. The stages of the movement that emerged were read from the perspective of Sidney Tarrow where there were five stages carried out by farmers. Analysis with the survival mechanism perspective of James Scott shows that during the struggle for land acquisition, farmers must reduce the quality of their food, make independent efforts to find additional income, so that a network is formed for them to survive and regain their agricultural land.

Abstrak
Penelitian ini membahas tentang munculnya gerakan sosial yang berbasis pada kemandirian petani di Piondo, Sulawesi Tengah. Gerakan muncul sebagai respon atas konflik antara petani dengan PT Kurnia Luwuk Sejati (KLS) dan PT Berkat Hutan Pusaka (BHP). Pencarian data dilakukan secara kualitatif dengan metode studi kasus. Tahapan gerakan yang muncul dibaca dengan perspektif Sidney Tarrow dimana ada lima tahapan yang dilakukan petani. Analisis dengan perspektif mekanisme bertahan hidup James Scott menunjukkan bahwa selama memperjuangkan pembebasan lahan, petani harus menurunkan kualitas pangannya, melakukan swadaya mencari tambahan pendapatan, hingga terbentuk jaringan bagi mereka untuk bertahan hidup dan mendapatkan kembali lahan pertaniannya.

Medical Crowdfunding and Disparities in Health Care Access in the United States, 2016‒2020
Authors: Kenworthy Nora , Igra Mark
Published: February 2022

Objectives. To assess whether medical crowdfunding use and outcomes are aligned with health financing needs in the United States.

Methods. We collected data on 437 596 US medical GoFundMe campaigns between 2016 and 2020. In addition to summarizing trends in campaign initiation and earnings, we used state- and county-level data to assess whether crowdfunding usage and earnings were higher in areas with greater medical debt, uninsured populations, and poverty.

Results. Campaigns raised more than $2 billion from 21.7 million donations between 2016 and 2020. Returns were highly unequal, and success was low, especially in 2020: only 12% of campaigns met their goals, and 16% received no donations at all. Campaigns in 2020 raised substantially less money in areas with more medical debt, higher uninsurance rates, and lower incomes.

Conclusions. Despite its popularity and portrayals as an ad-hoc safety net, medical crowdfunding is misaligned with key indicators of health financing needs in the United States. It is best positioned to help in populations that need it the least. (Am J Public Health. 2022;112(3):491–498. https://doi.org/10.2105/AJPH.2021.306617 )

» Functional acetabular safe zones based on patient-specific factors during total hip arthroplasty are theorized to result in more optimal component stability than the use of traditional safe zones based on static targets.

» Preoperative planning that takes into account functional pelvic positions and spinopelvic mobility is increasingly recommended.

» Computer navigation and robotics can be utilized to help accurately achieve the targeted cup position within the functional safe zone.

» Each technology platform (imageless and image-based computer navigation and robotics) utilizes a specific referencing method for the pelvis, which influences anteversion and inclination values.

» The purpose of this article is to summarize how these different systems reconcile differences in pelvic referencing to ensure that the surgeon achieves the targeted functional cup position.
Rhizo-inoculation of phosphate solubilizing bacteria strains to improve rice (Oryza sativa L. var. FARO 44) growth under ferruginous ultisol conditions.

Published: February 2022

The research investigated the possibility of phosphate solubilizing bacteria (PSB) with plant growth-promoting (PGP) capabilities to improve growth properties of rice plant under ferruginous ultisol (FU) condition through rhizo-inoculation strategy. The PSB with PGP properties used in this research were Bacillus cereus strain GGBSU-1, Proteus mirabilis strain TL14-1 and Klebsiella variicola strain AUH-KAM-9 that were previously isolated and characterized following the 16S rRNA gene sequencing. The rice seeds were sown in a composite FU soil sample and a humus soil (control) and then rhizo-inoculated along the root region of the growing rice seedling at 16 days after sowing. The rice plant was studied for differences in morphological, physiological and biomass parameters for 16 weeks after rhizo-inoculation. Results showed that the FU soil used in the study had high pH, low bioavailable phosphorus, low water holding capacity and high iron levels which has led to a low growth properties of rice seeds sown in FU soil without rhizo-inoculation. After rhizo-inoculation, a significant increase in plant height and physiological parameters were observed in the rice plant grown in the FU soil as against the control and the rice plant in FU soil without inoculation except for terpenoid which is usually known to signify biotic stress and as part of plant defense mechanism. Generally, rhizo-inoculation of rice seedling with the three PSBs under FU soil condition significantly improved growth properties of the rice plant. This suggest the ability of the PSBs to solubilize and mineralize soil phosphate and improve its availability for plant use in phosphate stressed soil, thereby improving plant growth properties.

Background: Meat yield and quality is one of the most important economic traits of livestock. Long non-coding RNAs (lncRNAs) is involved in the biological process of muscle differentiation and development. However, few studies have explored the regulatory role of lncRNA on muscle development after birth.Results: The longissimus dorsi muscle of Leizhou black goat aged 0, 3 and 6 months was used to identify differential mRNA and differential lncRNA by high-throughput RNA sequencing. GO, KEGG and interaction network were used to analyzed the differential genes. We found that some target genes of DE-mRNA and DE-lncRNA were mainly involved CN-NFAT signal pathway and the formation of branch fibers, which is related to normal muscle development. ENSCHIG00000006085 and ENSCHIG00000023270 are significantly concentrated in the biological process related to urea transporters, which has an important effect on maintaining the normal development of goats. ENSCHIG00000006085 and ENSCHIG00000023270 may be involved in the degradation of intracellular proteins and METTL11B may play a role in methylation modification of muscle proteins.Conclusions: Our results show that some lncRNAs are involved in the regulation of protein during goat muscle development as well as provide a valuable resource for lncRNA studies and make a deeper understanding of the genetic basis and molecular mechanisms of the development of goat skeletal muscle.

Published: February 2022

Background: Although there has been a global decrease in childhood diarrheal disease in parallel with improvements in the standard of living, it remains a significant public health problem that occurs due to poor WASH status and other related factors that cause massive childhood morbidity and mortality particularly in sub-Saharan Africa countries including Ethiopia. Objective: To assess diarrheal disease prevalence and associated factors among under-five children in the periphery area of Azezo sub-city, Gondar, northwest Ethiopia. Methods: A community-based cross-sectional study was conducted in April 2019. A simple random sampling technique was applied to recruit the eligible clusters/villages. Structured interview questionnaires were used to collect data. The completed data were entered into Epi Info version 7 and exported to SPSS version 20 for further analysis. A binary logistic regression model was used to process bivariate and multivariable analysis of the data to establish the association between dependent and independent variables. The adjusted odds ratio (AOR) with 95% CI was used for the interpretation of data after controlling the confounders. Results: The two-week prevalence of U5C diarrheal disease was 24.9 % with 95% CI: (20.4 – 29.7). Age group of 1-12months [AOR: 9.22, 95%CI: (2.93-29.04)], age group of 13-24months [AOR: 4.44, 95%CI: (1.87-10.56)], low monthly income (AOR: 3.68, 95% CI: (1.81-7.51)], small family size [AOR: 0.32, 95% CI: (0.16-0.65)], poor hand washing practice [AOR: 8.37, 95 % CI: (3.12-22.52), and immediate feed for cooked foods [AOR: 0.39, 95%CI: (0.19-0.81)] were significantly associated factors with childhood diarrhea. Conclusion: Diarrhea was a common health problem among under-five children in the periphery area of Azezo sub-city. Age of children, family size, monthly income, hand-washing practice, and feeding time for cooked food were identified statistically significant risk factors. Therefore, an appropriate intervention program through health education would be recommended with a focus on identified risk factors to reduce the burden of diarrheal diseases.

A successful transition towards renewable energy systems in the European Union is expected to improve growth, reduce greenhouse gas emissions and create employment. Analysing recent data from 28 European Union (EU) countries, we investigate the potential interlinkages in employment, renewable energy and non-renewable energy amongst the EU countries. We further examine assess the contributions of renewable energy and non-renewable energy to the future variation in employment, output and carbon emissions within the EU. Our results suggest that renewable energy has a positive and significant net employment impact for EU. We further find that renewable energy consumption contributes substantially to the future variability in employment both for the short and the medium term. Also, carbon-dioxide emissions negatively impact the employment level in the EU.

BackgroundBrain is the most important organ in resuscitation. NIRS-measured cerebral oxygenation is evolving brain monitoring tool for neonatal resuscitation.MethodWe undertook a prospective observational study for monitoring of cerebral oxygenation and peripheral preductal saturation at 1 , 5 and 10 minutes after birth to establish centile chart normative for monitoring of full term neonates during transition. Fractional tissue oxygen extraction was calculated as well. In addition to studying factors affecting cerebral oxygenation at those points in time.Results 60 healthy term neonates were enrolled to define reference ranges and centile charts of cerebral oxygenation at 1, 5, and 10 minutes after birth. The strongest correlations between cerebral oxygenation metrics and peripheral preductal saturation were at 5 minutes after birth. The most significant factor affecting NIRS-measured crSO2 in healthy full term neonates was mode of delivery. This work was registered in the cinicaltrial.gov NCT05158881.Conclusions Normal references of cerebral oxygenation metrics can be used to guide intervention during neonatal resuscitation. Caesarean section is the most significant factor affecting cerebral oxygenation during the transition of healthy full term neonates.
