How water, temperature and seismicity control the preparation of massive rock slope failure (Hochvogel, DE/AT)
Authors: Leinauer Johannes , Dietze Michael , Knapp Sibylle , Scandroglio Riccardo , Jokel Maximilian , Krautblatter Michael
Published: February 2024

Abstract. The increasing hazard of major rock slope failures, exacerbated by climate change, underscores the importance of anticipating pre-failure process dynamics. While standard triggers are recognized for small rockfalls, few comprehensive driver quantifications exist for massive pre-failure rock slopes. Here we exploit >4 years multi-method high-resolution monitoring data from a well-prepared high-magnitude rock slope instability. To quantify and understand the effect of possible drivers – water from rain and snowmelt, internal rock fracturing and earthquakes – we correlate slope displacements with environmental data, local seismic recordings and earthquake catalogues. During the snowmelt phase, displacements are controlled by meltwater infiltration with high correlation and a time lag of 4–9 days. During the snow-free summer, rainfall drives the system with a time lag of 1–16 h for up to several days without a minimum activation rain sum threshold. Detected rock fracturing, linked to temperature and freeze-thaw cycles, is predominantly surface-near and unrelated to displacement rates. A classic Newmark analysis of recent and historic earthquakes indicates a low potential for immediate triggering of a major failure at the case site, unless it is already very close to failure. Seismic topographic amplification of the peak ground velocity at the summit ranges from a factor of 2–11 and is spatially heterogeneous, indicating a high criticality of the slope. The presented methodological approach enables a comprehensive rockfall driver evaluation and indicates where future climatic changes, e.g. in precipitation intensity and frequency, may alter the preparation of major rock slope failures.
Continued warming of deep waters in Fram Strait
Authors: Karam Salar , Heuzé Céline , Hoppmann Mario , de Steur Laura
Published: February 2024

Abstract. Fram Strait is the only deep gateway between the Arctic and the rest of the World Ocean, and is thus a key region to understand how the deep Arctic will evolve. However, studies and data regarding the deep ocean are scarce, making it difficult to understand its role in the climate system. Here we analyse oceanographic data from the deep ocean from two long-term mooring locations (F11 and HG-FEVI) in Fram Strait between 2010–2023, to investigate long-term changes in the hydrographic properties. We compile hydrographic profile data since the 1980’s for additional context in the upstream basins: the Greenland Sea, and the Eurasian Basin. At mooring F11 in western Fram Strait, we find a clear seasonality, with increased Greenland Sea Deep Water (GSDW) presence during summer, and increased Eurasian Basin Deep Water (EBDW) presence during winter. Evaluating long-term changes, we find a modest temperature increase of ∼ 0.1 °C for EBDW since the 1980’s. For GSDW, south of Fram Strait, we find a strong temperature increase of ∼ 0.4–0.5 °C for the same period. The different warming rates have led to GSDW becoming warmer than EBDW since ∼ 2017/2018. This means that the Greenland Sea is no longer a heat sink for the Arctic Ocean at depth, but a heat source. It is therefore possible that EBDW temperatures will increase faster in the future.

Authors: Menut Laurent , Cholakian Arineh , Pennel Romain , Siour Guillaume , Mailler Sylvain , Valari Myrto , Lugon Lya , Meurdesoif Yann
Published: February 2024

Abstract. A new version of the CHIMERE model is presented. This version contains both computational and physico-chemical changes. The computational changes make it easy to choose the variables to be extracted as a result, including values of maximum sub-hourly concentrations. Performance tests show that the model is 1.5 to 2 times faster than the previous version for the same set-up. Processes have been modified and updated such as turbulence, transport schemes and dry deposition. Optimization was also performed for the management of emissions such as anthropogenic and mineral dust. The impact of fires on wind speed, soil properties and LAI was added. Pollen emissions, transport and deposition were added for birch, ragweed, olive, grass. The model is validated with a simulation covering Europe with 60×60 km resolution and the entire year of 2019. Results are compared to various measurements, and statistical scores show that the model provides better results than the previous versions.

Published: February 2024

This article demonstrates the impact of sustainability accounting with its dimensions: environmental, economic, and social on the quality of financial reports of ASE-listed pharmaceutical and chemical firms. To achieve the research objectives, the applied approach based on the financial reports and statements of the research sample firms is used as the main source of research data between (2016) and (2021). A sample of (27) firms is selected from the number of firms in the field of various industries that represent the research population of (53) firms, i.e. (51%) of the research population that meets the criteria for selecting the research sample. Statistical methods are also used to test the hypotheses and attain the results. The findings indicate that the environmental, economic, and social dimensions of sustainability accounting activities partially or completely affect the financial reports’ quality through simple and multiple regression models. The results of the statistical analysis also show that increasing the reporting of sustainability dimensions leads to an increase in the financial reports’ quality of the firms under research. From the research perspective, it is a logical result as the firms’ departments and regulatory institutions tend to provide appropriate and complete information to the beneficiaries and stakeholders. The research recommends supporting the ASE-listed firms that adopt initiatives related to reporting on sustainability accounting, including the Fourth Generation Global Reporting Initiative (GRIG4), and reviewing the listing and disclosure instructions on the ASE by including reporting on sustainability accounting as one of the main requirements for disclosure and listing on the stock exchange.

The aim of this research was to examine the role that business schools in Palestinian universities played in achieving Sustainable Development Goals (SDGs) (G1, G4, G8, G9, G12, G16, G17) through their study plans, due to their close connections to the local market. Additionally, the study aimed to determine whether business school graduates acquire the skills and competencies necessary for the local market. For this descriptive and analytical study, a survey questionnaire was created to collect data from faculty members and employers in the local market. The findings show that business schools in Palestinian universities have included SDGs in their study plans to a medium-to-high degree, with a stronger focus on quality education. Employers in the local market view graduates from these study plans as having the necessary competencies and skills, and they also rate their compliance with SDGs as being between moderate and high, particularly in quality education. Regarding the degree to which the competencies and skills of business school graduates meet those of the local market and are thus relevant to SDGs, there were no significant differences between the perceptions of university faculty members and employers in the local market. However, notable significant differences were found in the areas of international standardization, capacity knowledge in operational expertise, economic and industrial challenges, and partnerships for the goals. Business schools in Palestinian universities should continue to set a high priority on incorporating SDGs into their study plans and matching the competencies and skills of their graduates with the demands of the local market. The considerable areas of variance between employers in the Palestinian market and university faculty members present opportunities for greater collaboration to meet the requirements of the local market and accomplish SDGs.

Authors: Peker Ünal Dilşat , Nalbant Aygül
Published: February 2024

This study was conducted to determine the opinions of elementary teachers about the child abuse and neglect education program developed according to the quantum learning model. This study was carried out with the participation of 20 elementary teachers working in the Yozgat province of Turkey. Quantitative and qualitative research methods were used together. Within the scope of the quantitative research, the “In-Service Training Programs Evaluation Scale” developed by Tekin and Yaman in 2008 was used. This scale had two factors and 28 items. The Cronbach’s alpha coefficient of the scale in the original study was 0.95. Within the scope of the qualitative research, open-ended structured questions were asked to determine the opinions of elementary teachers on child abuse and neglect and the quantum learning model. Descriptive statistics and descriptive analysis were used in the analysis of the data. As a result of the analysis, it was determined that the opinions of teachers on the in-service training program were positive; they considered the quantum learning model as a physics-related model that developed the student in all aspects; they did not plan to implement the quantum learning model in the classroom; and they found it positive that the quantum learning model and child abuse and neglect were handled together. Teachers also reported that parents should participate in the training program on child abuse and neglect. The teachers acquired the learning outcome “Knows that he/she should call the Alo 183 social support line in case of child abuse and neglect” at the end of the training program. As a result of the study, recommendations were made regarding the nature of the courses to be organized for teachers, the arrangements that can be made in schools for the implementation of the quantum learning model, and the need to organize educational programs for parents.

Published: February 2024

This study identified non-tuberculous mycobacteria (NTM) isolates from the clinical respiratory specimen of patients suspected of chronic tuberculosis at a tertiary referral hospital in Indonesia. In this study, 20 clinical non-tuberculous mycobacteria (NTM) isolates were obtained from respiratory samples examined in the tuberculosis section of the Clinical Microbiology laboratory at Dr Soetomo General Hospital. The isolates were identified using TB Ag MPT 64 (SD Bioline) and targeting 16S rRNA genes sequence for analysis at the species level. Data on clinical features were collected and chest radiographs were evaluated. The highest bacterium found in the isolates was Mycobacterium kansasii (12 strains, 60%.), followed by Mycobacterium gordonae (2 strains, 5%), Mycobacterium parascofulaceum (2 strains, 5%), Mycobacterium avium (1 strain, 2.5%), Mycobacterium simiae (1 strain, 2.5%). Mycobacterium abcessus (1 strain, 2.5%), and Mycobacterium paraterrae (1 strain, 2.5%). Males dominated patients with Mycobacterium kansasii. Clinical symptoms include cough, dyspneu, hemoptysis, chest pain, and sweats. Half of the patients had a history of previous tuberculosis and other comorbid diabetes mellitus. Non-tuberculous mycobacteria (NTM) species identified were dominated by Mycobacterium kansasii. The predominance of non-tuberculous mycobacteria (NTM) species from clinical respiratory can be a reference to determine prudent treatment for patients in high-burden TB countries.

The primary objective is to challenge and dismantle patriarchal norms while amplifying the voices of marginalized single women. The journal invites submissions from various theoretical perspectives, including feminist theory, intersectional feminism, queer feminism, and postcolonial feminism. These perspectives will be utilized to examine and contextualize the experiences of single women in Jakarta. Breaking the Patriarchal Mold will feature scholarly articles, personal essays, and creative works that delve into the experiences of single women in Jakarta. It is anticipated that the journal will shed light on the diverse experiences of single women in Jakarta and provide insights into how patriarchal norms and societal expectations impact their lives. The journal's findings will contribute to the broader discourse on feminism, singleness, and women's empowerment in Indonesia. Additionally, it will promote gender equality and social justice in the region. Breaking the Patriarchal Mold will serve as a platform to elevate the voices of single women in Jakarta, challenge prevailing patriarchal structures, and advocate for greater gender equality and social change.
Impact of Online Discount on Indian Shoppers During Festive Seasons: An Analytical Study
Authors: Dr. Akshat Dubey Dolly Tripathi,
Published: February 2024

With the increasing preference of Indians to shop online instead of visiting physical stores, the retail sector in the country is undergoing significant transformation. Several factors are fueling the rapid rise in popularity of online shopping in India. These include the increasing internet penetration, a growing number of internet-savvy consumers, a larger labour force, a wide range of online stores offering goods from around the globe, and improved web accessibility. The concept of "e-tailing" refers to the business model where products are bought and sold through an online platform. India's retail sector is currently undergoing a significant transformation due to the transition from traditional stores to online marketplaces. During the festival season, online retailers are currently offering a variety of deals to attract more customers. In recent years, the popularity of online shopping has soared, allowing consumers to easily purchase a wide range of products, from everyday essentials to cutting-edge technology. Online shopping and digital shops are becoming increasingly popular in rural areas, reaching beyond the confines of city life. Several factors contribute to this phenomenon, such as increasing incomes, a stronger economy, a wide range of choices for consumers, and the active involvement of lenders in promoting digitalization and online shopping. The festival shopping sector is a significant driver behind the growth of e-commerce platforms. During holiday seasons, companies frequently offer promotions and significant discounts on both new and used products. In addition, they offer additional incentives such as cash-back deals and buy-one-get-one sales. At this time, companies would organise sales events with distinctive names such as "Big Billion Days" on Flipkart, "Flash Sales" on Myntra, and "Great Festive Sale" on Amazon. The aim of this study is to examine the impact of virtual shopping festivals on local communities and individual shoppers.
Social enterprise, food justice, and food sovereignty: Strange bedfellows or systemic supports?
Authors: Merritt Katherine , Clark Jill , Freedman Darcy
Published: February 2024

There is a debate in the literature about whether one can address food system problems with mar­ket-based approaches while seeking food justice or food sovereignty. However, as part of a team of researchers and community leaders, we have found that this debate is less relevant in practice. The concepts are interrelated within real-world food systems. As such, we were motivated to ask, how do social enterprises (SEs) interact with food jus­tice and food sovereignty movements and their visions in order to realize more democratic and equitable local food systems in communities? To answer this question, we conducted a systematic review at the intersection of SE, food sovereignty, and food justice literature. Analyzing nine articles, which included 17 food-related SEs, we found evi­dence of potential interactions between food SEs, food justice, and food sovereignty that are compat­ible (e.g., create employment) and incompatible (e.g., limited ability to address issues like commu­nity employability and green gentrification). The lit­erature includes at least three important character­istics that inform how food-related SEs may interact with food justice and sovereignty, includ­ing employee and ownership demographics, the enterprise business model, and aspects of the food system targeted by the enterprise via market activi­ties. If we consider a systems perspective, we can envision the ways in which the aspects are embed­ded and interdependent in a neoliberal society. SEs, as market-based agents for social change, exist in the same system as justice and sovereignty.

Published: February 2024

Cholera is an acute diarrhoeal disease caused by Vibrio cholerae (VC) serogroups O1 and O139. Transmission is oro-faecal and it might lead to acute dehydration. The disease is still endemic in resource-poor countries, nevertheless importation cases are occasionally reported in developed countries. The paper reports a case of a 3-year-old boy admitted to the emergency room because of acute gastroenteritis with rice-water stools. Faecal samples were positive for VC. The child was managed with prompt parenteral crystalloid infusion, followed by oral rehydration solution. After a single dose of azythromicin, a progressive reduction in symptoms was documented. Cholera infection is then briefly reviewed.

Introduction:

The purpose of this study was to evaluate surgeons' ability to perform or supervise a standard operation with agreed-upon radiologic parameters after being on call.

Methods:

We reviewed a consecutive series of patients with intertrochanteric hip fractures treated with a fixed angle device at 9 centers and compared corrected tip-apex distance and reduction quality for post-call surgeons versus those who were not. Subgroup analyses included surgeons who operated the night before versus not and attending-only versus resident involved cases. Secondary outcomes included union and perioperative complications.

Results:

One thousand seven hundred fourteen patients were of average age 77 years. Post-call surgeons treated 823 patients and control surgeons treated 891. Surgical corrected tip-apex distance did not differ between groups: on-call 18 mm versus control 18 mm (P = 0.59). The Garden indices were 160° on the AP and 179° on the lateral in both groups. In 66 cases performed by surgeons who operated the night before, the TAD was 17 mm. No difference was noted in corrected tip-apex distance with and without resident involvement (P = 0.101). No difference was observed in pooled fracture-related complications (P = 0.23).

Conclusion:

Post-call surgeons demonstrated no difference in quality and no increase in complications when performing hip fracture repair the next day compared with surgeons who were not on call.

Authors: Jabeen Aniqa , Mushtaq Sumara , Ahmed Bashir , Hashmi Hina
Published: February 2024

In a unique clinical presentation, a 20-year-old female with a known left distal Tibial Osteoblastoma (previously treated via curettage) developed pain and weight-bearing difficulties in her left lower limb six months later. Subsequently bone scan revealed a unprecedented clinical presentation: residual activity in the treated Osteoblastoma alongside additional foci of increased tracer uptake on skeletal scintigraphy, localized to the bilateral anterior superior and inferior iliac spines. Subsequent radiographs confirmed sessile bony outgrowths in these locations, consistent with multiple pelvic Osteochondromas (an uncommon variant). Notably, these Osteochondromas lacked associated radiolucencies or cortical destruction. Further MRI confirmed the Osteochondroma diagnosis. Interestingly, the patient declined surgical intervention for the asymptomatic Osteochondromas, prioritizing ongoing treatment for the primary Osteoblastoma. This case highlights the rare co-occurrence of these distinct tumor types in an uncommon usual pelvic location, emphasizing the importance of patient centered treatment approach based on patient preferences and clinical context.
Comparative analysis of machine learning algorithms for biomedical text document classification: A case study on cancer-related publications
Authors: Kucuk Ekrem , Cicek Ipek , Kucukakcali Zeynep , Yetis Cihan
Published: February 2024

Biomedical text document classification is an essential task within Natural Language Processing (NLP), with applications ranging from sentiment analysis to authorship identification. Despite advancements in traditional machine-learning algorithms like Support Vector Machines (SVM) and Logistic Regression, challenges such as data sparsity and high dimensionality persist. Recent years have seen a surge in the use of deep learning models to mitigate these issues. This study aims to conduct a comparative analysis of various machine-learning algorithms for classifying biomedical text documents. The study employs the "Medical Text Dataset - Cancer Doc Classification" from Kaggle, comprising 7570 biomedical text documents labeled into three types of cancer (colon, lung, and thyroid). A preprocessing pipeline involving tokenization, stop-word removal, and Term Frequency-Inverse Document Frequency (TF-IDF) vectorization is applied. Algorithms including Logistic Regression, SVM, and Multinomial Naive Bayes are evaluated through 5-fold cross-validation. Performance metrics like accuracy, precision, recall, F1 score, and area under the ROC curve (AUC ROC) are employed. Logistic Regression outperforms the other algorithms with an accuracy of 78.3% and an AUC ROC of 88.59%. SVM and Multinomial Naive Bayes follow with lower performance metrics. Hyperparameter tuning further enhances the performance of the algorithms, particularly Logistic Regression. The study makes a significant contribution to the field of biomedical text classification by systematically comparing machine-learning algorithms. Logistic Regression emerges as the most effective, emphasizing the importance of algorithm selection and hyperparameter tuning in machine learning applications within this domain.
Muscle strength and endurance in COPD patients and healthy individuals – A comparative study
Authors: K Parveen , M Ranjini , R Hemavathy , A Dhamayanthi
Published: February 2024

Background: Many studies have been done with COPD patients focusing on the impairment of lung function in these patients. However, only few studies were done focusing on the impairment of skeletal muscle strength and endurance in COPD patients which if occurs will affect their quality of life.

Aim and Objective: The aim of this study is to compare the skeletal muscle strength and endurance between COPD patients and age gender and body mass index (BMI)-matched healthy subjects. We also assessed the association between decrease in FEV1 and muscle strength and endurance.

Materials and Methods: 40 male COPD patients and age and body mass index-matched healthy male subjects were studied. Dominant hand-forearm muscle strength and endurance were measured using handgrip dynamometer. FEV1, FVC, and FEVI/FVC were measured using spirometer. Muscle strength and endurance between two groups were compared and the correlation between FEV1 and muscle strength and endurance was analyzed.

Results: Mean muscle strength and endurance were significantly lower in COPD patients (P < 0.001) compared to healthy subjects. Significant positive correlation between decrease in FEV1 and decrease in muscle strength (P < 0.001) and endurance (P < 0.05) was observed.

Conclusion: This study shows that there is decrease in muscle strength and endurance in COPD patients. Hence, early intervention to improve muscle strength is needed for better quality of life in these patients.
Arteries of a Changing Arctic: Small Rivers on a Global Scale
Authors:   , Speetjens Niek Jesse
Published: February 2024

This thesis explores the intensification of the freshwater cycle under ongoing climate change through the lens of a specific landscape type: The ice-wedge polygon tundra. Permafrost degradation plays an important role in the shifting arctic biogeochemical cycle and large uncertainties exist regarding arctic land-ocean fluxes. The manuscript focuses on three investigations:
1. Local scale study: The study examines an Arctic lowland watershed in a permafrost degradation zone near the Arctic Ocean shoreline. The findings reveal differences in soil porewater DOM properties and DOC concentrations between different thermal layers and landforms, impacting hydrology and biogeochemical fluxes. Lateral fluxes of dissolved organic matter (DOM) from soil to streams are influenced by polygon type and drainage patterns.
2. Global scale inventory: The thesis highlights the lack of focus on smaller arctic river systems in scientific literature when upscaling lateral fluxes to the pan-Arctic scale. We present a comprehensive circum-arctic catchment database, which contains over 140 climatic, physiographic, and environmental variables. This database allows for the identification of catchments draining into the Arctic Ocean and their associated characteristics. Notably, smaller catchments in the northernmost regions, underlain by continuous permafrost and featuring substantial permafrost-specific terrain types, are found to be more vulnerable to temperature increases and are crucial in lateral carbon fluxes.
3. Modeling lateral fluxes: The thesis proposes a conceptual hydrological-biogeochemical model for ice-wedge polygon terrain to simulate runoff and DOC flux. The model indicates increased lateral flux in catchments transitioning from low-centered to high-centered polygon-dominated landscapes due to increased drainage and subsequent DOC export.
The research emphasizes the importance of studying lateral biogeochemical fluxes from permafrost landscapes and the challenges in quantifying these fluxes. It suggests the need for improved field studies, data collection, and the development of scalable models to better predict and understand the impacts of permafrost thaw and climate change on Arctic ecosystems and the global carbon budget.
The Legacy of Human Impact on European Landscapes: Insights from Holocene Vegetation Change
Authors:   , Zapolska Anhelina
Published: February 2024

This thesis focuses on exploring the extensification of anthropogenic land use in Europe during the second half of the Holocene (the last 6 thousand years) and its profound impact on landscape development. The study investigates human-landscape interactions by analysing existing anthropogenic land cover change scenarios and comparing them with archaeological knowledge to track the timing and spatial distribution of two major energy regime transitions: the transition to agriculture (Agricultural energy regime) and the shift to the era of fossil fuels (Industrial energy regime). To quantify the cumulative human impact on European land cover, the study compares modelled potential natural vegetation (without human impact) with reconstructed land cover derived from pollen-based reconstructions (include human impact). A novel methodology for mitigating model biases in palaeoclimate modelling is tested and applied to ensure a meaningful comparison between the two data types within the study's intercomparison workflow. The findings highlight significant differences between mid-Holocene vegetation cover and the state of potential natural vegetation, leading to further investigation into the effects of pre-agricultural foraging societies on landscapes during the Eemian and early Holocene periods through the assessment of available proxies to reflect human impact.

Berdasarkan studi pendahuluan yang dilakukan di SD Negeri 1 Mawah menunjukkan bahwa jumlah seluruh siswa kelas I-VI sebanyak 131 siswa. Pelaksanaan pendidikan kesehatan (perilaku mencuci tangan) masih jarang dilakukan oleh pendidik khususnya dalam menanamkan perilaku mencuci tangan yang benar.  Selain itu orang tua masih sering membiarkan anaknya tidak mencuci tangan sesudah bermain atau mengkomsumsi makanan ringan. Mencuci tangan pakai sabun adalah salah satu  proses yang  secara tepat dan benar merupakan cara termudah dan efektif untuk mencegah berjangkitnya penyakit. Mencuci tangan dengan air dan sabun dapat lebih efektif menghilangkan kotoran dan debu secara mekanis dari permukaan kulit dan secara bermakna mengurangi jumlah mikroorganisme penyebab penyakit seperti virus, bakteri dan parasit lainnya pada kedua tangan. Penelitian ini bertujuan untuk mengetahui pengaruh pendidikan kesehatan terhadap pengetahuan mencuci tangan selama pandemi Covid-19 pada siswa di SDN 1 Mawah Kecamatan Wawonii Kabupaten Konawe Kepulauan. Jenis penelitian ini adalah penelitian pre eksperimen dengan pendekatan “One Group Pre dan Post Test Design. Populasi penelitian adalah seluruh siswa SDN 1 Mawah sebanyak 131 orang dengan jumlah sampel 57 orang. Teknik pengambilan sampel menggunakan Accidental sampling, Metode analisis menggunakan Uji Paired T test. Hasil penelitian menunjukkan bahwa ada pengaruh pendidikan kesehatan terhadap pengetahuan mencuci tangan selama pandemi Covid-19 pada siswa di SDN 1 Mawah Kecamatan Wawonii Kabupaten Konawe Kepulauan (p value = 0,000 < 0,05), dimana terdapat 35 responden (61,4%) yang memiliki pengetahuan mencuci tangan kategori cukup dan 22 responden (38,6%) yang memiliki pengetahuan mencuci tangan kategori kurang. Sedangkan untuk pemberian pendidikan kesehatan dari 57 responden, terdapat 50 responden (87,7%) yang memiliki pengetahuan mencuci tangan kategori cukup dan terdapat 7 responden (12,3%) yang memiliki pengetahuan mencuci tangan kategori kurang.

Gastritis menjadi masalah kesehatan dihadapi sekarang banyak menyerang kalangan remaja maupun dewasa, penderita gastritis di Indonesia tahun 2018 tertinggi pada laki-laki 17,396 kasus dibandingkan perempuan 12,758 kasus. Puskesmas Abeli mengalami peningkatan kasus gastritis pada pria dari tahun 2020 hingga tahun 2022. Penelitian ini bertujuan untuk mengetahui faktor risiko kejadian gastritis pada pria di wilayah kerja Puskesmas Abeli Kota Kendari. Jenis penelitian adalah penelitian kuantitatif dengan rancangan Case Control Study. Populasi dalam penelitian adalah populasi kasus 483 orang dan populasi kontrol 2.526 orang, teknik penarikan sampel secara Stratified Random Sampling.  Sampel penelitian ini adalah sampel kasus dan sampel kontrol sebanyak 50 orang dengan perbandingan 1:1 matching umur sehingga jumlah sampel keseluruhan adalah 100 orang. Analisis data menggunakan uji Odds Ratio. Hasil uji statistik menunjukkan bahwa konsumsi kopi (OR= 4,696, LL=1,931-UL=11,418), merokok (OR= 3,807, LL= 1,657-UL= 8,747), dan konsumsi alkohol (OR=4,030, LL=1,712-UL=9,488) merupakan faktor risiko kejadian gastritis pada pria di wilayah kerja Puskesmas Abeli Kota Kendari. Diharapkan pihak Puskesmas Abeli meningkatkan pelayanan kesehatan seperti pos binaan terpadu dan memberikan edukasi khususnya penderita gastritis yang memiliki kebiasaan kurang baik dilihat dari mengkonsumsi kopi, merokok dan mengkonsumsi alkohol.

Introduction: Most robot-assisted surgery (RAS) systems in Canada are donor-funded, with constraints on implementation and access due to significant costs, among other factors. Herein, we evaluated the impact of the growing multispecialty use of RAS on urologic RAS access and outcomes in the past decade.
Methods: We conducted a retrospective review of all RAS performed by different surgical specialties in two high-volume academic hospitals between 2010 and 2019 (prior to the COVID pandemic). The assessed outcomes included the effect of increased robot access over the years on annual robotic-assisted radical prostatectomy (RARP) volumes, surgical waiting times (SWT), and pathologically positive surgical margins (PSM). Data were collected and analyzed from the robotic system and hospital databases.
Results: In total, six specialties (urology, gynecology, general, cardiac, thoracic, and otorhinolaryngologic surgery) were included over the study period. RAS access by specialty doubled since 2010 (from three to six). The number of active robotic surgeons tripled from seven surgeons in 2010 to 20 surgeons in 2019. Moreover, there was a significant drop in average case volume, from a peak of 40 cases in 2014 to 25 cases in 2019 (p=0.02). RARP annual case volume followed a similar pattern, reaching a maximum of 166 cases in 2014, then declining to 137 cases in 2019. The mean SWT was substantially increased from 52 days in 2014 to 73 days in 2019; however, PSM rates were not affected by the reduction in surgical volumes (p<0.05).
Conclusions: Over the last decade, RAS access by specialty has increased at two Canadian academic centers due to growing multispecialty use. As there was a fixed, single-robotic system at each of the hospital centers, there was a substantial reduction in the number of RAS performed per surgeon over time, as well as a gradual increase in the SWT. The current low number of available robots and unsustainable funding resources may hinder universal patient access to RAS.

Introduction: Neoadjuvant chemotherapy (NAC) is the standard of care for patients undergoing radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC); however, NAC can be associated with significant side effects and morbidity in some patients. NAC may contribute to sarcopenia, obesity, and the combination of the two. Our study examined the effects of NAC on body composition and the association between body composition and adverse events.
Methods: We created a retrospective database of patients with non-metastatic MIBC receiving NAC prior to RC. The change in skeletal muscle index (SMI) and fat mass index (FMI) was calculated using computed tomography (CT) scans done within three months prior to NAC and after the first two cycles. The association between body composition (sarcopenia, obesity, and sarcopenic obesity) and preoperative adverse events was investigated using a multivariable logistic regression. Changes in body composition were calculated using a paired Student’s t-test.
Results: A total of 70 patients were included in our study. There was a mean decrease in SMI of 2.2±3.2 cm2/m2. Adiposity and FMI were unchanged by NAC. Sarcopenic obesity was found to be associated with adverse events among patients receiving NAC in the multivariable analysis. There were a total of 637 preoperative complications with grades 1–2 and 33 complications with grades 3–5.
Conclusions: Based on our retrospective cohort study, NAC did not affect obesity and FMI, but there was a significant decrease in SMI. Sarcopenic obesity was associated with increased severity of NAC adverse events. As such, the presence of this factor may help predict tolerance of NAC.
