Published: May 2024

Background: Bangladesh, like many developing countries, is experiencing population ageing. There is inadequate information regarding the prevalence of malnutrition and functional dependency in community-living rural senior residents in this country. The study aims to determine the nutritional status and functional capacity of the rural elderly population of Chattogram District of Bangladesh and to search for its associated factors. Methods: This community-based cross-sectional study included 213 subjects aged 60 years and over from two Upazilla of Chattogram district by a multistage random sampling technique. Sociodemographic and clinical data were collected using a structured questionnaire, nutritional status was assessed with the Mini Nutritional Assessment-Short Form (MNASF) tool and functional assessment was done using the Modified Barthel self-care index (BSI).Results: The participants’ mean age was 66.1 ± 6.5 years and 51.6 % was female. More than half of the participants (45.4%) were illiterate. The majority of them were living in a joint family with their spouse. About 70% of the participants were from lower socioeconomic classes, 82.2% were not engaged in any vocational activity, 74.6% were entirely dependent economically on others, and 110 (51.6%) had multi- morbidity. The prevalence of malnutrition and risk of malnutrition were 29.9% and 56.8% of the study sample, respectively. About 44% of the participants need help to perform their daily activities. Poor nutritional status was significantly more frequent in elderly subjects aged more than 70 years, in respondents living without a partner, and in older people with multi-morbidity. Conclusion: Poor nutritional status was commonly observed among older adults living in rural areas in Chattogram. The associated factors should be further considered for targeting particularly vulnerable individuals.

Published: May 2024

Background: Epithelial ovarian carcinoma is the major subtype of ovarian cancer, one of the most lethal gynaecological malignancies. Due to some difficulties in early detection, patients are usually diagnosed at advanced stages, and overall survival is poor. P16 is a tumour suppressor gene that regulates the cell cycle by inhibiting S phase. Studying experssion of this immunohistochemical marker will help to diagnose and predictrognosis of ovarian epithelial tumours. The study’s objective was to evaluate the expression of p16 in surface epithelial ovarian neoplasm and its association with histo-pathological grading.
Methodology: This cross-sectional study was carried out at the Department of Pathology, Sir Salimullah Medical College, Dhaka. A total of 46 patients diagnosed histo-pathologically as surface epithelial ovarian neoplasm were included in the study. In addition, P16 immuno-staining, as well as some demographic and clinical data, were also evaluated.
Result: The mean age of the patient was 48.04 ± 12.182SD years. The most common histologic subtype was serious, followed by the mucinous type. P16 was positive in 40 (86.96%) cases. A statistically significant difference in p16 expression was observed between tumour types and between tumour grades. Up-regulation of p16 expression was observed in malignant tumours more than in benign tumours. P16 expression was increased with increased grading of the malignant tumours.
Conclusion: P16 expression is associated with histo-pathological grading in ovarian epithelial carcinoma.

Authors: Abedin Mohammad Raisul , Afzalul Haque Abu Hasanat Muhammad , Shamsuzzaman Sheikh Mohammad
Published: May 2024

Background: Duplex ultrasound is a non-invasive evaluation of blood flow in the major arteries and veins. It provides a unique spectrum of details, including the anatomical location of the lesion, accompanied by further information about flow velocity and volume. Day by day, this investigation has become popular among physicians and surgeons to evaluate peripheral arterial disease.
Objective: To determine duplex scans’ accuracy in diagnosing peripheral arterial disease and correlate it with clinical diagnosis.
Materials & Methods: The cross-sectional study was conducted in the Department of General Surgery in collaboration with the Department of Radiology & Imaging, Dhaka Medical College Hospital, and Dhaka from January 2011 to December 2011. A total of 100 clinically diagnosed cases of peripheral arterial disease, irrespective of age and sex, were included in the study. However, emergency cases of peripheral arterial disease and patients of peripheral arterial disease with concomitant cerebrovascular disease or venous pathology or arterio-venous malformation were excluded from the study. Based on clinical signs and symptoms, a clinical diagnosis was made, correlated with the diagnosis made by duplex scan findings.
Result: Peripheral arterial disease was mainly confined to the lower limb (85%). The right limb was involved in about two-thirds (64%) of the cases, the left limb in 31%, and both limbs in 5% of cases. More than 90% were a smoker. Pain and intermittent claudication were the universal complaints of the patients, followed by hair changes (85%), colour changes (86%) and wasting of the limb (65%). The most commonly involved arteries in the lower limb were arteria dorsalis pedis (96.6%), followed by the posterior tibial artery (84.2%), popliteal artery (60.6%), and femoral artery (21.3%). In the upper limb, the radial artery was involved in 100% of cases and the brachial artery in 86.7% of cases. Endarteritis obliterans and atherosclerosis were common clinical diagnoses (47% and 48%, respectively). Diagnosis based on duplex scan findings also demonstrated that endarteritis obliterans and atherosclerosis were common (40% and 39%, respectively), bearing consistency with clinical diagnosis. The strength of agreement between the two diagnoses was moderate (k = 0.743).
Conclusion: The study concludes that there was a moderate agreement between Clinical diagnosis and duplex diagnosis, which indicates that a duplex scan can be a valuable tool to support clinical diagnosis, suggest other diagnoses, or detect other associated pathologies.

Strongyloides stercolaris is a common intestinal nematode in tropical and subtropical countries like Bangladesh. The presentation of this infection is nonspecific. Mostly it remains asymptomatic with peripheral eosinophilia. Immunocompromised individuals are at high risk of hyper infection to disseminated disease. We present a case of Strongyloides in an immunocompetent patient with features of gastric outlet obstruction. Laboratory findings revealed hypereosinophilia with multiple gastrointestinal ulcers on endoscopy. Biopsy was taken from a gastric ulcer which revealed ulceration and dense infiltration of acute and chronic inflammatory cells along with extensive intestinal metaplasia. There were tiny helminthic bodies within the mucosal glands and on the surface consistent with Strongyloides stercoralis. Routine examination of stool also revealed larvae of Strongyloides stercolaris.

Authors: Auryn Shania , Agushybana Farid , Widjanarko Bagoes
Published: May 2024

The presence of comorbid diseases has become a crucial concern in confronting the COVID-19 pandemic, underscoring the need for the implementation of GERMAS (Healthy Living Movement) policy as a preventive measure initiated by the government. GERMAS aims to control the increase in non-communicable disease cases, which have the potential to disrupt human resources and productivity, as well as negatively impact social and economic development. In its implementation, GERMAS must adhere to the principles of Good Governance to ensure transparency, community participation, accountability, effectiveness, efficiency, responsiveness, and consensus. This research aims to analyze Transparency, Participation, Accountability, Effectiveness and Efficiency, Responsiveness, and Consensus. This research employs a qualitative approach with a narrative method and in-depth interviews with 12 informants. While GERMAS has been implemented since the President's directive in 2017, there are still several challenges in enhancing its effectiveness. Analysis of Good Governance principles highlights issues such as lack of community participation, low transparency and inter-agency coordination, and insufficient attention to inactive GERMAS forums. Further research is needed to deepen understanding of GERMAS implementation in Kutai Barat, focusing on aspects such as inter-sectoral communication, community participation, and enhancement of accountability of relevant agencies. Concrete steps such as comprehensive performance audits and increased social media outreach can help improve policy implementation.

Cognitive Improvement in Thermodynamic Functions With Calculus Chain Rule
Authors: Simangunsong Sumihar
Published: May 2024

This research was motivated by the low ability of students to apply mathematical solution methods to thermodynamic functions. Thermodynamic functions are functions that consist of pressure, temperature, volume and enthalpy functions where changes in one function can occur due to changes in other functions. The aim of this research was to show the implementation of chain rules in thermodynamic function problems by relying on a process technique to improve students' cognitive awareness of thermodynamic functions. The place of this research was at the TD Pardede Institute of Science and Technology. The process of understanding chain rules is very impactful for understanding thermodynamic state functions. Differential decomposition of functions within functions is also described in the chain rule method. Thermodynamic functions which consist of pressure, temperature, volume and enthalpy functions can depend on each other so that the chain rule analysis method can be clearly used. With this method students will also be given the opportunity to connect one concept with other thermodynamic concepts. Apart from that, this method can be used anywhere. This shows a cognitive increase in terms of cognitive elements, cognitive structure and cognitive function.

Authors: Hawsawi Aisha Ali , Nixon Neil , Derbyshire Alice , Nixon Elena
Published: May 2024

Medical students' psychological wellbeing is a growing concern. However, the methods used and outcomes measured in studies evaluating psychological wellbeing lack consistency given their wide and diverse array. This systematic review aims to characterise and comprehensively evaluate the outcomes measured and methods used in studies assessing psychological wellbeing among medical students. A consensus on the constructs and methods used in indexing psychological wellbeing can lead to more effective assessments and consequently more effective interventions aimed at promoting wellbeing in medical students. Methods: Multiple databases were searched, including Medline, PsycINFO, Cochrane Library, and Web of Science. Grey literature was searched through Google Scholar, and reference lists of the included studies were further searched. Results: Forty-five studies were included, and findings were integrated into a narrative synthesis. The results showed that various methods were used and various outcomes were measured to index medical students’ mental wellbeing; outcomes tapped on stress, depression, anxiety, burnout, and minor psychiatric disorders as wellbeing indicators while commonly used measures were the General Health Questionnaire, Oldenburg Burnout Inventory, Perceived Stress Scale and Depression Anxiety Stress Scale. Self-reported measures and quantitative designs predominated, focusing on negative indicators of wellbeing. The findings of this systematic review highlighted the vast heterogeneity in outcomes measured and methods used in studies assessing psychological wellbeing in medical students. Conclusions: Homogeneity in the measures and outcomes used to assess wellbeing is necessary to improve the comparability and reliability of findings among studies. Future research should also use validated measures that capture both positive and negative aspects of psychological wellbeing to gain a more comprehensive understanding of the factors that can promote positive psychological wellbeing; and consequently, to inform the development of more effective interventions tailored to the mental health needs of medical students.

Sea-ice and macrozooplankton distribution as determinants of top predator community structure in Antarctic winter
Authors: Czapanskiy MF , Santora JA , Dietrich KS , Cimino MA , Hazen EL , Reiss CS , Veit RR
Published: May 2024

The Antarctic Peninsula marine ecosystem is highly productive, with large populations of commercially and ecologically important species including Antarctic krill Euphausia superba, Adélie penguins Pygoscelis adeliae, and crabeater seals Lobodon carcinophagus. The ecology of the peninsula is rapidly changing due to accelerating climate change and fishing pressure. Systematic ecosystem surveys have focused on austral spring and summer, leaving an information gap on winter ecosystem dynamics. Using data from 5 consecutive ecosystem surveys, we quantified the composition and distribution of winter predator communities and investigated the physical and biological influences on community structure. Seabirds and marine mammals clustered into 3 communities: an ice-associated community represented by Adélie penguins and crabeater seals; a diverse marginal ice zone community dominated by fur seals and several species of seabirds including 3 petrels, kelp gulls Larus dominicanus, and Antarctic terns Sterna vittata; and an open water community consisting of southern fulmars Fulmarus glacialoides and 4 species of petrels. These communities were distributed along an environmental gradient ranging from ice-covered, cold, saline water to ice-free, warmer, and fresher water with greater chlorophyll concentrations. Predator communities were also associated with different communities of macrozooplankton: ice-associated predators with an extremely diverse assemblage of typically mesopelagic zooplankton; marginal ice zone predators with a community of large-bodied euphausiids (E. superba, E. crystallorophias); and open water predators with a community of small-bodied euphausiids (Thysanoessa macrura). Our synthesis of integrated winter predator and macrozooplankton communities relative to sea-ice concentration provides reference points for future ecosystem assessments within this rapidly changing region.
Proportional top-down effects of grapsoid crabs on growth of Spartina maritima cordgrass in southern African salt marshes
Authors: Smit LA , Adams JB , Hawkes SA , Peer N , Rishworth GM
Published: May 2024

Salt marsh productivity has historically been viewed as being driven primarily by bottom-up processes, but recent studies in North America, Europe, Asia and South America have shown that top-down forces by grazers also structure marsh vegetation. This generality of grazing pressure has not been tested to date in African salt marshes. Here, we investigated whether dominant crabs in South Africa’s estuarine marshes consume live plants and whether that interaction has direct effects on the foundational species Spartina maritima. We employed natural surveys, lab feeding trials, diet analysis and field experiments. Although we found no significant relationships between crabs and marsh plant structure in surveys, gut contents and stable isotope analysis showed that S. maritima is present but not prominent in their diet. All S. maritima components were consumed. Manipulation of crab density and size structure in the field (crabs >5 mm excluded) revealed small effects on S. maritima stem density and aboveground biomass compared to controls. Combined, this research demonstrates that crabs in these South African marshes do indeed eat live cordgrass, and their effects appear to be density dependent. Top-down impacts on marsh plants were not detected by natural density correlations, probably due to the different scales at which data were collected compared to field experiments. These results establish that grazing of live foundational marsh plants is globally common. Future studies in these systems should manipulate crab density through addition experiments or predator exclusions to understand the impact of crabs at high densities and what forces regulate their populations.

Authors: Bakhteeva G. R. , Erokina N. L. , Lepilin A. V. , Rogatina T. V. , Savelyeva S. S. , Mukhina N. M.
Published: May 2024

Relevance. Fractures of the mandibular fracture are a stressor on the body and lead to changes in the functioning of the autonomic nervous system. At the same time, patients with mandibular fractures often experience local changes in the nervous system associated with the anatomical and physiological features of the location of the third branch of the trigeminal nerve and its damage. These changes affect the course of the post-traumatic period and may increase the likelihood of complications of mandibular fractures.

Purpose: to determine the significance of disturbances in the functioning of the nervous system during the post-traumatic period of fractures of the mandibular fracture.

Materials and methods. When examining 130 patients with fractures of the mandibular fracture, the state of the autonomic nervous system and local neurological changes were studied.

Results. In patients with mandibular fractures, dysfunction of the autonomic (autonomic) nervous system and local neurological changes were revealed.The severity of these changes is reflected in the development of complications of fractures. When studying the autonomic nervous system in patients with mandibular fractures, there was an increase in the activity of the sympathetic nervous system, which increased the likelihood of developing complications of mandibular fractures. A high incidence of injury to the inferior alveolar nerve was also found. The most pronounced deviations in autonomic balance indicators – pathological increased excitability of the autonomic nervous system – were diagnosed in patients with complicated fractures of the mandibular fractures. In most patients with complicated mandibular fractures, damage to the trigeminal nerve was detected, confirming the role of neurotrophic disorders in the development of complications.

Conclusion. With fractures of the mandible, there is an increase in the activity of the sympathetic nervous system, which increases the likelihood of complications. The most pronounced deviations in autonomic balance indicators were diagnosed in patients with complicated fractures of the mandible. In addition, in patients with mandibular fractures, a high incidence of damage to the inferior alveolar nerve was revealed; in complicated fractures, neuropathy is severe, which confirms the role of neurotrophic disorders in the development of complications. Thus, methods for preventing purulent-inflammatory complications in jaw fractures should include correction of neurological disorders.

Introduction. Materials based on extracted teeth in various studies have been radiographically and histologically proven to be effective in osteoplastic operations. These materials can be used in the form of crushed dentin matrix, a fragment of the tooth’s root and an autogenous dentin block. The purpose of this clinical case was to evaluate the effectiveness of using an autogenous dentin block to increase the alveolar process of the jaws in the preimplantation period.

Description of a clinical case. Patient F., 30 years old, applied to the clinic of the Clinical Center of Maxillofacial, Plastic Surgery and Dentistry Russian University of Medicine with a complaint of a missing tooth in the frontal region of the lower jaw. At the time of treatment, the patient was already undergoing orthodontic treatment in another medical institution in Moscow. The patient underwent a clinical and radiological examination together with a prosthodontst. A diagnosis of «partial secondary adentia», «atrophy of the alveolar ridge in the frontal part of the lower jaw» and «dystopia of teeth 1.8, 2.8, 3.8, 4.8» was established. A comprehensive treatment plan has been drawn up. At the first stage, the patient underwent extraction of teeth 1.8, 2.8, 3.8, 4.8 for orthodontic indications with simultaneous bone grafting of the alveolar ridge in the area of the missing tooth 3.1. At the second stage, the patient underwent a trephine biopsy in the area of augmentation and installation of a dental implant in the area of missing tooth 3.1. The third stage was rational prosthodontic treatment on a dental implant in the department of prosthodontics.

Results. The present study showed that autogenous dentinal block can serve as an alternative material for alveolar ridge augmentation.

The article presents the results of the outcomes analysis of osteoplasty in the rehabilitation of patients using dental implants, examines its various types and biological factors affecting the success of these operations. An attempt has been made to find possible solutions to the problem of bone insufficiency in the treatment of patients with missing teeth.

The aim of the study is to study the results of various bone grafting techniques in patients in preparation for dental implantation and the success factors of this surgery.

Materials and methods: the results of 281 osteoplasties were evaluated. The patients were divided into 4 groups according to the surgery technique performed: guided bone regeneration (GBR); bone block transplantation (BBT); open sinus-lifting (OSL); local bone modifying (LBM). Complications and results of these surgeries were evaluated.

Results: significant and critical complications were more common in the operations of GBR (61.7% and 21.28%, respectively) and BBT (28.57%). After evaluating the outcomes of osteoplastic surgery, it was found that the acceptable result of OSL was 93.27%, LBM 88.43%; while we noted an unacceptable result during GBR in 76.59%, and BBT 57.14%. Complications in the form of non-critical reversible ones were more common during OSL (42.3%), however, significant and critical complications were detected after operations of GBR (61.7%) and BBT (28.57%). The results of the analysis of the outcomes of bone plastic surgery in the oral surgery indicate a significant percentage of unsuccessful outcomes of the GBR (76.59%) and BBT (57.14%).

Conclusion: the study demonstrates the clinical value and effectiveness of various osteoplasties’ methods. In our opinion, outcomes and complications is associated, among other things, with a different factors, the main of which are the number of existing bone walls of the defect (atrophy), the volume of replacement, age and localization, which must be taken into account when predicting the results of this surgery.

Relevance. The article is devoted to the issue of diagnosing the condition of the jaw bone tissue in children with mixed dentition. The relevance of the study is related to the increased consumption of chewing gum by children.

The purpose of this study was to evaluate the echodensity of the jaw bone tissue in patients with mixed dentition using chewing gum with varying intensity.

Materials and methods. We examined 31 children, the average age was 8.5±1.2 years. It is at this age that the active formation of facial morphology and anatomy takes place, which is directly related to the condition of the jaw bones. For diagnosis, an ultrasound technique was chosen – osteometry. This method is based on assessing the speed of propagation of ultrasound waves along the surface of the bone. In addition, in comparison with radiation, ultrasound methods for studying bone tissue have significant advantages, expressed in the reliability of the results obtained, low cost of procedures, ease of use, absence of radiation for personnel and patients, and minimal research time. From a practical point of view, this method is the most accessible in a dental office. Echoosteometry was carried out using the Echoosteometer EOM-01TS apparatus.

Results. Based on the study, it was revealed that there was an imbalance in bone density in children who actively used chewing gum.

Araştırmanın amacı, otel işletmelerinde çevik liderlik, mesleki öz yeterlilik, yaratıcılık ve işe gömülmüşlük arasındaki ilişki ve bu ilişkide örgütsel özdeşleşmenin aracı rolünün olup olmadığını tespit etmektir. Araştırmanın örneklemi, Antalya’da Kemer ilçesinde faaliyet gösteren 5 yıldızlı otel işletmelerindeki işgörenlerdir. Verilerin toplanmasında anket yönteminden yararlanılmıştır. Anket uygulaması 1 Nisan-31 Ağustos tarihleri arasında kolayda örnekleme tekniği ile gerçekleştirilmiş ve toplamda 220 anket elde edilmiştir. Veriler SPSS Statistics 26.0 ve Amos Graphics 22.0 istatistik programlarından yararlanılarak test edilmiştir. Elde edilen sonuçlara göre çevik liderliğin mesleki öz yeterliliği, yaratıcılığı işe gömülmüşlüğü ve örgütsel özdeşleşmeyi pozitif yönde etkilediği, ayrıca çevik liderliğin mesleki öz yeterlilik, yaratıcılık ve işe gömülmüşlük arasındaki ilişkisinde örgütsel özdeşleşmenin aracılık rolünün olduğu tespit edilmiştir. Ortaya konulan araştırma çevik liderlik konusunun otelcilik sektöründe çok az ele alınması ve ele alınan konu ile ilgili yeni bir model ortaya koyması açısından önem arz etmektedir.
Нормативна база функціонування художніх промислів УРСР у повоєнний період (1944-1949)

У статті характеризується нормативна база функціонування художніх промислів УРСР в кооперативному секторі економіки повоєнного часу до 1949 р., коли ліквідували мережу обласних і міжобласних художніх промислових спілок (художпромспілок) і підпорядкували артілі безпосередньо республіканському центру. З’ясовано, що до складу нормативної бази входили документи органів різного рівня державного управління: союзного, республіканського й обласного. Ними визначалися напрямки розвитку художньої промислової кооперації й основні організаційні способи розв’язання її проблем. Деякі документи ухвалювалися також ЦК ВКП(б) або ЦК КП(б)У, що надавало їм більшої значущості. У системі галузевого функціонування нормативні акти теж продукували за вертикаллю, але кооперативного управління, до складу якого входили Українська кооперативна промислова спілка, Українська, міжобласні й обласні художпромспілки. Їх нормативна творчість (інструкції, положення, правила, статути) здебільшого стосувалася поточного функціонування кооперативних підприємств. Назагал нормативна база діяльності художніх артілей досліджуваного періоду сприяла самостійності їх функціонування.

Covid-19 merupakan penyakit infeksi pernapasan akut yang disebabkan oleh corona virus strain severe acute respiratory syndrome corona virus 2 yang dapat dengan mudah menyebar dan ditularkan melalui jalur pernapasan penderita terinfeksi. Gejala Covid-19 umumnya berupa demam 38°C, batuk kering, dan sesak nafas serta dampak paling buruk untuk manusia ialah kematian yang dapat disebabkan oleh adanya penyakit penyerta seperti hipertensi diabetes mellitus, jantung koroner dan penyakit serebrovaskula. Masyarakat di sekitar kampus STIKES Al-Irsyad Al- Islamiyyah Cilacap masih terlihat belum terbiasa menggunakan masker pada saat keluar rumah. Kurangnya Upaya preventif saat di luar rumah dengan membawa handsanitizer dikarenakan persediaan dan harga dipasaran yang melambung tinggi (mahal) sehingga masyarakat mengalami kendala pada saat membelinya. Tujuan dari pengabdian masayarakat ini adalah untuk menciptakan Gerakan Masyarakat Cerdas Menggunakan Hand Sanitizer Dan Masker Sebagai Upaya Preventif Terhadap Covid-19. Metode pangabdian yaitu berupa donasi masker dan handsanitizer serta pemberian informasi pemakaiannya secara lisan. Hasil yang diperoleh adalah 120 orang sasaran sudah mendapatkan handsanitizer dan 120 orang mendapatkan masker diserati leaflet berkaitan dengan covid-19. Dengan demikian, masyarakat sekitar kampus dapat menggunakan masker dan perbekalan handsanitizer pada saat keluar rumah.
