Authors: Quraishi Twinkle Furial , Rahman Aminur , Mahmudul hakim Khondker , Ali Shapnil Ahammed , Hakim  Mishu Mahbubul
Published: May 2024

Hereditary motor and sensory neuropathies with early onset are uncommon conditions that include Dejerine-Sottas neuropathy, which begins in infancy, and congenital hypomyelinating neuropathy, which manifests in the early postnatal period. However, these two historically defined disease entities are only small parts of the clinical spectrum. It is well recognized that very early onset hereditary neuropathies are frequently caused by de novo dominant mutations in PMP22, MPZ, and EGR2. In addition, mutations in several other dominant and recessive genes for Charcot-Marie-Tooth disease may lead to similar phenotypes. A 20-year-old boy had complaints of weakness of both lower limbs for 1 year, followed by wasting and foot drop, which subsequently involved the upper limbs. Nerve conduction velocity and electromyography of both lower limbs revealed demyelinating sensory motor polyneuropathy. Histological examination of the sural nerve revealed a nerve trunk with perineural soft tissue, with the nerve bundles being irregular and separated by fibrous tissue bands. The later reveals small perivascular infiltration of chronic inflammatory cells, and no granuloma or AFB is seen. The genetic test of whole exome screening for heriditatory neuropathy showed pathogenic (PM2, PVS, PP5) with a gene impact of (NF2: c.363+1G>T), which is a rare entity in our case study to consider the diagnosis despite negative family history. We highlight this rare disease in young man with a high index of clinical suspicion for its diagnosis.

Authors: Ali Md Yousuf , Rahman Aminur , Zakia Kazi Ismat , Paul Sanjoy Kumar , Mim Maisha Zerin
Published: May 2024

Background: Patients with advanced CKD stages exhibit a markedly elevated risk of cardiovascular disease. Patients with chronic kidney disease (CKD) exhibit an elevated cardiovascular risk manifesting as coronary artery disease, heart failure, arrhythmias, and sudden cardiac death .The main objective of this study was to observe the clinical epidemiology of cardiovascular disease in advanced stages of CKD prior to dialysis to a tertiary care centre in Bangladesh. Methods: This was a cross-sectional observational study on 150 cases of diagnosed advanced stages (4&5) of CKD patients in the indoor Department of Medicine of Sir Salimullah Medical College Mitford Hospital, Dhaka, Bangladesh from July 2022to January2023 for 6 months. Data was analyzed SPSS 25. Results: Out of the total group, 62.0% are male, 38.0% are female, and the average (mean) age of the entire group was 55.2 ±10.3. Patients are compared in terms of their relative percentages and the associated cardiovascular disease (CVD) risk, with the hypothesis that lower hemoglobin levels (<9 mg/dL), common in advanced CKD, may be associated with higher CVD risk. A statistically significant P-value (0.036) indicates a significant association between lower hemoglobin levels and increased risk of CVD. Hypertension is the most common risk factor in both stages showing (80%) in stage 4 and 86.6% in Stage -5 of CKD respectively that increasing prevalence as stages of CKD increases . Other factors like diabetes 50.6%) and 53.3% , dyslipidemia 61.3% and 66.7% , and family history of cardiovascular disease (CVD) 40% and 46.6% also in prevalence from Stage 4 to Stage 5. However, the differences in the prevalence of these risk factors between the two stages are not statistically significant, as indicated by the P-values. The prevalence of Congestive Heart Failure rises from 44% in Stage 4 to 52% in Stage 5, and a similar trend is observed in Coronary Artery Disease from 40% in Stage 4 to 48% in Stage 5 and for other diseases, albeit with lesser increments. The provided pvalues, which assess statistical significance, indicate that the differences in disease prevalence between the two stages are not statistically significant, suggesting that the progression from Stage 4 to Stage 5. Conclusion: This study stated that increased prevalence and progression of cardiovascular risks in advanced CKD stages.

Artificial Intelligence in Medicine: A New Frontier
Authors: Haque Md Azizul , Quazi Tarikul Islam
Published: May 2024

Artificial intelligence (AI) refers to the engineering and science of making intelligent machines through algorithms or rules, mimicking human cognitive functions, such as learning and problem-solving. AI has several branches, such as machine learning and deep learning, which can add intelligence to applications. Machine learning is the study of algorithms that allow computer programs to improve automatically through experience. Deep learning algorithms learn from an extensive, multi-layered collection of interconnected processes and expose these processors to many examples. In the coming years, the integration of AI in routine medical care is expected to revolutionize Medicine, potentially improving patient care and quality of life. The time required for a diagnosis can be greatly reduced, and diagnostic efficiency can be significantly enhanced when AI assists clinicians. Large language model chatbots are capable of clinical expert-level medical note-taking, consultation, and questionanswering. Chatbotscan generate human-like text, may help diagnose diseases based on medical records, and may suggest treatment options or plans. Artificial intelligence algorithms, particularly deep learning, have demonstrated remarkable progress in radiological image analysis and diagnosis and may improve radiologists’ efficiency. These algorithms may also improve diagnostic accuracy in dermatology, histopathology, fundoscopy, endoscopy, and other medical images. Natural language processing and ambient clinical intelligence automate administrative duties like recording patient visits in electronic health records, streamlining clinical workflow, and freeing up doctors to spend more time with patients. AI may also help with new drug discoveries, precision medicine, and clinical research. AI developments can revolutionize several healthcare-related fields and pave the way for a more individualized, accurate, predictive, and portable future.

Authors: Afzalul Haque Abul Hasanat Muhammad , Abedin Mohammad Raisul , Zaman Md Farooque z , Shoma Farzana Khan , Bhuiyan Abdullah Tareq , Kollol Humayun Kabir
Published: May 2024

Background: Incentive spirometry (IS) is a device used to improve pulmonary function. It is a device that provides patients with visual feedback when they inhale at a predetermined flow rate/volume, sustain the inflation for a minimum of 3 seconds, and then expire. It is postulated that incentive spirometry (IS) might play a significant role in preventing and treating postoperative pulmonary complications. However, we need more research-based information on this issue.
Objective: The aim of the study was to assess the effectiveness of incentive spirometry in improving pulmonary function following urologic surgery in elderly patients.
Methods: This comparative study was conducted in the department of Urology, Dhaka medical college hospital (DMCH), Dhaka, Bangladesh, from January 2021 to December 2021. In total, 150 elderly people were included as the study subjects. The total subjects were divided into two groups. In group A, there were 75 patients who received incentive spirometry in addition to deep breathing, coughing and early ambulation. In Group B, there were also 75 patients, denoted as control group patients, who received standard care of treatment including deep breathing, coughing and early ambulation without incentive spirometry. All data were collected, processed, and analyzed by using MS Office and SPSS-18 programs as per need.
Results: In this study in incentive spirometry, postoperative VAS, FVC, FEV1, and FEV1/FVC scores were 5.29±1.73, 1.25±0.61, 1.21±0.45 and 88.61±18.44 respectively. On the other hand, in Group B (Non incentive spirometry), postoperative VAS, FVC, FEV1, and FEV1/FVC scores were 5.71±1.57, 1.14±0.56, 1.09±0.22 and 91.57±19.91 respectively. We found a significant correlation in comparing FEV1 (Forced Expiratory Volume) between both groups, with a P value of 0.040. In this study, in Group A (IS), only 8% of elderly patients of urological surgery were found with postoperative pulmonary complications. On the other hand, in patients without using Incentive spirometry, one-fifth (20%) were with postoperative pulmonary complications.
Conclusion: As per the findings of this study, both treatment methods are effective. But patients’ compliance may be better in applying Incentive spirometry (IS) in urological surgery in elderly patients. Physicians can minimize the possibilities of postoperative pulmonary complications by using Incentive spirometry.

Authors: Hossain Mohammad Afjal , Atiquzzaman - , Sharifuzzaman Mirza , Yasmin Marufa , Siddiqui Nazia Afrin , Amin Farzana , Rahman Mohammad Lutfar
Published: May 2024

Background: Subclinical hypothyroidism (SCH) is a common endocrine disorder affecting about 3-8% of the general population. On the other hand, mean platelet volume (MPV) is an indicator of platelet activity, and elevated MPV is associated with adverse cardio-metabolic complications. This study was conducted to observe MPV in SCH and to correlate it with thyroid-stimulating hormone (TSH) and free thyroxine (FT4) levels.
Materials and Methods: This cross-sectional observational study was conducted in Medicine and Endocrinology OPD of US- Bangla Medical College & Hospital over twelve (12) months from September 2020 to August 2021. This study included forty (40) cases of newly detected SCH and twenty (20) age & body mass index (BMI) matched euthyroid control subjects as per inclusion and exclusion criteria.
Results: SCH group had higher TSH and MPV than controls (P value <0.001 and <0.05 respectively) where age, BMI, and FT4 level were comparable (P value>0.05). MPV shows a positive correlation with BMI in SCH & controls (P values <0.05). MPV shows a significant positive correlation with TSH and a negative correlation with FT4 only in SCH (P<0.05) but not in controls (P value>0.05).
Conclusion: Patients with SCH have elevated MPV, so they are at increased risk of developing an adverse cardiovascular outcome.

Authors: Islam Sharmin , Rahman Ayesha , Elahi Mahboob , Nahar Mst Jesmen , Sultana Salma , Tani Sadia Afrin , Jamal ABM
Published: May 2024

Background: Breast cancer is the second leading cancer worldwide (2089 million new cases per year, 11.6%) after lung cancer and 5th most leading cause of death (6.6%). The breast clinic concept is to set up a center of a cohesive group of dedicated breast cancer specialists working together as a multidisciplinary team with access to all the facilities required to deliver highquality care throughout the breast cancer pathway.2 The guidelines note that these professionals do not necessarily have to be based in one location but do need to be in the same geographical area and able to carry out close multidisciplinary work. To provide uniform management of breast diseases, hospital-based breast cancer screening, and properly manage breast cancer patients, we restarted this breast clinic weekly on Thursday in the Outpatient Department of Surgery in Dhaka Medical College Hospital, 2018.
Method and Materials: A 1year observational study was done from 1st August 2018 to 31st July 2019. All female patients having breast problems are included in this study by purposive sampling technique. The total number of patients was 620. A database kept using a registrar book, Microsoft Excel, and documents.
Results: Out of 620 patients, 26% presented with mastalgia, 50% with a breast lump, 15% with Fibrocystic changes, 4% with nipple discharge, 2 cases with duct papilloma, 2% duct ectasia, and 4% with others. Among the breast lumps, 42% presented with different stages of Carcinoma Breast, 32.4% with Fibroadenoma, 4% with galactocele, 8% breast abscess, 2% with breast TB, 9% with Chronic breast abscess including Granulomatous mastitis.
Conclusions: Females are half of the total population, but attention to their problems is not given to that much extent. Therefore, they often presented their symptoms lately. Though mastalgia is a rare symptom of breast cancer, patients are over-conscious regarding breast pain. In contrast, a painless malignant lump grows in its pattern and advances to the T3-4 stage at the presentation time. So providing comprehensive breast care as well as screening with multidisciplinary experts and equipment is a burning need for every tertiary-level hospital.

Background: Previous infection or vaccination boosts up the body’s immune system. It may have a protective effect or an exaggerated immune response. Knowledge about the impact of vaccination or previous infection on the presentation and outcome of the new variant of COVID- 19 is scarce.
Objectives: In this study, vaccine effectiveness, reinfection rate and severity prediction among vaccinated and non-vaccinated COVID-19 infected patients were assessed.
Methods: This observational study was conducted in the COVID-19 unit of Dhaka Medical College Hospital. Three hundred forty-four patients who presented in the triage and were admitted to DMCH were enrolled as per inclusion criteria and were followed up for three months for outcome variables. Patients were divided into four groups by vaccination and previous infection. Results: Mortality was 18(14.6%), 10(14.3%), 14(22.6%), and 40(44.9%) in new COVID-19 in vaccinated, reinfection in vaccinated, new COVID-19 infection in unvaccinated, and reinfection in unvaccinated patients respectively. 5 (4.1%) of the newly infected vaccinated and 4 (6.5%) freshly infected unvaccinated, 14 (15.7%) reinfected unvaccinated patients were transferred to ICU for mechanical ventilation. The mean duration of the hospital stay was significantly (p<0.05) lower among the vaccinated group than in non-vaccinated patients.
Conclusion: This study suggests that vaccination of previously infected people may be associated with reducing the adverse outcome of COVID-19 infection.

Authors: Kurnia Esti Eva , Nursalam Nursalam , Junait Junait
Published: May 2024

Communication failures in information transfer during intraoperative handover can pose a risk to patient safety incidents. One of the factors influencing the success of intraoperative handover is the existence of a structured handover checklist. This study aimed to explain the implementation of a structured intraoperative handover checklist to improve information transfer during intraoperative handovers. The design employed was a literature review. Articles were selected from databases including ScienceDirect, Scopus, PubMed, and Springer Link. The criteria for article selection included publication between 2017 and 2022, full text in English, and the use of keywords such as 'intraoperative handover,' 'handover checklist,' and 'information transfer.' The PRISMA flowchart stages were utilized to filter appropriate articles. The critical assessment of article quality employed The Joanna Briggs Critical Appraisal Tools 2020 and Mix Methods Appraisal Tool 2018. The results of the review of 8 articles indicated that a lack of good coordination during intraoperative handovers often occurs due to the absence of structured guidelines regarding handover content. The application of an intraoperative handover checklist has been shown to increase the completeness of data transfers and reduce the percentage of information omission during the handover process. The implementation of structured intraoperative handovers has a positive influence on improving the quality of communication between surgical teams and reducing incomplete information conveyed. A structured intraoperative handover checklist is needed as a guide to reduce the number of errors in information transfer, thus enhancing patient safety.

Exploring the relationship between perceptual learning style preferences (PLSP) and foreign language class anxiety (FLCA)
Authors: Firissa Berhanu , Gebremariam Alamirew
Published: May 2024

The study investigating a relationship between perceptual learning style preferences (PLSP) and foreign language class anxiety (FLCA) remains limited, particularly regarding specific learning styles most impacted by FLCA and interventions to be tailored to reduce English class anxiety. The study examined the relationship between PLSP and FLCA among 110 grade eleven Mettu Comprehensive High School students. The study employed a PLSP questionnaire (Pashler et al., 2009) and an FLCA questionnaire (Horwitz et al., 1986) as the instruments. Data were collected, statistically analyzed, and interpreted using SPSS version 26. The study’s findings revealed that most participants' FLCA fell to the average higher level while those with group (PLSA-G) PLSP exhibited the least FLCA compared to participants with the individual (PLS-I) with the highest FLCA among the six dimensions of PLSP. Communication anxiety (FLCA-CA) significantly and fear of negative evaluation (FLCA-FNE) broadly were found to be the major sources of the participants’ sources of FLCA among its three dimensions in the scale. Furthermore, results of One-way ANOVA confirmed that PLSP is significantly and moderately related to FLCA. It was inferred that the constructs PLSP and FLCA play significant roles in the context of EFL teaching. Therefore, EFL instruction needs to address these variables as determinants of the learners’ success, and if meaningful pedagogical room is to be allocated, teaching practices need to pay attention to such.   This area of exploration can lead to significant advancements in EFL pedagogy, creating a more inclusive and successful learning experience for students.

The aim of this research is to overcome the problem of mental retardation in developing mathematical potential and talent, especially abilities in social arithmetic by providing learning media adapted to the characteristics of mentally retarded students in the form of 3D comics with Indonesian cultural nuances based Technology Pedagogical Content Knowledge (TPACK) assisted by money pyramid media. This is because 11 of the 13 students are still not familiar with the new currency issued by Bank Indonesia, making it difficult for them to spend money. 3D comic media contains stories about traveling to three places in the archipelago which include Bali, Yogyakarta and Bogor, the embossed effect on the paper gives a three-dimensional impression so that it attracts the attention of mentally retarded students to learn using 3D Comics. The money pyramid media is used as the initial foundation for introducing money from one thousand to one hundred thousand denominations to mentally retarded students. The subjects in this research were 13 mentally retarded students in class X C using research methods in the form of experiments. Based on the results of research conducted using data processing, it was found that there were differences in the learning outcomes of mentally retarded students before and after being given treatment in the form of using 3D comic media with nuances of Indonesian culture and money pyramids. The amount of effectiveness in using media influences the learning outcomes of mentally retarded students by 67% in the quite effective category.

The problem faced in schools is the inconsistency in the selection of media used in the learning process. The primary consideration in choosing learning media is selecting media that can meet the needs or achieve the desired learning objectives. Therefore, feasibility testing is required for a learning media to address these issues. This study aims to assess the feasibility of video media produced by Jogja Belajar Media (JB Media) on trigonometry as a learning media. The research employed descriptive qualitative research with content analysis as the method. The analysis considered four aspects: content/material aspect, media/curriculum aspect, design aspect, and user aspect. The study used a validated instrument for assessing learning media. Based on the results from three assessors, the percentage of feasibility for the content aspect was 63.33%, media aspect 59.17%, design aspect 66.67%, and user aspect 68%. Thus, overall, it is categorized as feasible with a percentage of 64.29%. The video has not comprehensively considered some important aspects in the development of learning media, thus students cannot use it as a primary learning source to its fullest extent. Therefore, improvements are needed to support the comprehensive use of learning media.

This research aims to determine the increase in the development of cognitive abilities through playing monopoly with loosepart media in group A children at DARUL HIKMAH Kindergarten. This type of research is classroom action research. Each cycle consists of four stages, namely (1) action planning, (2) action implementation, (3) observation, and (4) reflection. The subjects of this research were group A at DARUL HIKMAH Kindergarten, totaling 10 children. The object of research is children's cognitive abilities through the monopoly media MAK ROUND. Data collection techniques used in this research include: observation, interviews/question and answer, and documentation. The research instrument used in this research is an observation sheet that has been validated by experts. The cognitive development indicators studied include four development standards, namely recognizing simple classifications, recognizing numbers, recognizing arithmetic operations, and recognizing geometric shapes. Before being given treatment (pre-cycle) using MONOPOLY MAK ROUND, of the four standards for the development of cognitive abilities, there was only one development standard that was above the average standard of completeness, namely recognizing numbers with an average of 30.5 and a percentage of 76.25%. After treatment in cycle I, four development standards increased and all of them were above the average completion standard.
Monitoring Strategies of Suspended Matter after Natural and Deep-Sea Mining Disturbances

The world’s oceans are increasingly under pressure from human activities, leading to warming and acidification of ocean waters, overexploitation of living resources, and uncontrolled dispersion of plastic litter and other pollutants. The advance of deep-sea mining poses yet another threat, especially to the unique, vulnerable, and largely unknown deep-sea life. The excavation of metal-rich mineral deposits from the deep-sea bed will not only remove hard substrate which deep-sea fauna like sponges and corals need for settlement; it will also produce sediment plumes which will be dispersed by currents, and which are expected to affect deep-sea life over a much wider area than the actually mined area. If deep-sea mining will be given green light, strict monitoring of these sediment plumes will be needed to ensure that the dispersal of sediment plumes and concentrations of suspended particulate matter (SPM) therein will not exceed prescribed thresholds. In my PhD research I have explored strategies for effective monitoring of sediment plumes produced by deep-sea mining, with a focus on different sensor types that can be used for measuring SPM and how these sensors can best be deployed in monitoring. Field experiments in which the performance of commonly used turbidity sensors was tested in different setups and were carried out in the Whittard Canyon and the Rainbow hydrothermal vent field in the Atlantic Ocean, where enhanced suspended particle concentrations occur naturally, thereby serving as “natural laboratories”, and in the Mediterranean Sea offshore southern Spain and the Clarion-Clipperton Zone in the Pacific Ocean, where sediment plumes were produced artificially.
Turning through disorder

With every breath you take, you can inhale dangerous particles. The respiratory system relies on mucociliary transport (MCT) to clear the airways of such particles. This works as follows: deposited particles are captured by a mucus layer lining the airways, and this mucus layer is propelled out of the lungs by the beating action of ciliated cells that collectively create a flow. Mucus consists of mucins which give the suspension elastic properties.

In this thesis, we focus on a specific structure, bundled mucus strands, present in the upper airways of large mammals. These strands are created in submucosal glands and can be millimetric in length. Once they are released from the glands, they come together to form large networks, that catch large particles and drag these out of the airways. We devised minimal models by which we could numerically investigate how bundled strands contribute to MCT. Specifically, we were interested in how such strands reorient from an orientation parallel to the direction of the flow, when they just emerge from the gland, to a perpendicular orientation. We studied the role of surface interactions, involving another mucin structure, and local inhomogeneities in the fluid flow. We found that both can drive reorientation, but that surface interactions best fit the experimental observations.

We also considered a simple model for a microswimmer in a (model) viscoelastic environment, to see how the motion of such a particle is affected by its surroundings. In connecting to experiments, we found that local contact dynamics are key in capturing its reorientation.
Theoretical frameworks and tools to support processes for future healthcare ecosystems

An evidence ecosystem and a learning healthcare system are connected as sub-systems of a symbiotic healthcare ecosystem in this thesis. Theoretical frameworks and tools are thereafter presented to support processes for organizations participating in such a symbiotic ecosystem. For the learning practice, a framework is provided to evaluate the best practice. This information could be exchanged as mirroring information for other practices. Furthermore, a framework is presented to design processes to continuously maintain clinical practice guidelines and systematic reviews. This framework is thereafter extended with the role and performance of priority-setting assessments in the context of maintenance strategies when there are insufficient resources available to maintain everything. To further support organizations aiming to develop and use a priority-setting assessment, a frame of reference identifying three components (that is process, function, and outcome) was provided and a tool was developed as a function component. Once it is known which guidelines and systematic reviews have enough priority to be maintained, the subsequent processes need to be efficient. An example is provided of how efforts by systematic review authors can be re-used to develop a guideline segment more efficiently. Nonetheless, all efforts are in vain if the product cannot be applied by the end-user. Thus, finally, the end-user in clinical practice is connected to the evidence translator. For this, considerations and guidance are given to translate difficult to interpret data about diagnostic test performance to a more easily understandable format.

Az evidenciaalapú orvoslás alapvető módszerei közé tartozik a gyógyszeres terápia. A 2005. évi XCV. törvény szerin gyógyszernek nevezett „bármely anyag vagy azok keveréke, amelyet emberi betegségek megelőzésére vagy kezelésére alkalmazható termékként jelenítenek meg, vagy azok az anyagok vagy keverékei, amelyek farmakológiai, immunológiai vagy metabolikus hatások kiváltása révén az ember valamely élettani funkciójának helyreállítása, javítása vagy módosítása, illetve az orvosi diagnózis felállítása érdekében az emberi szervezetben vagy emberi szervezeten alkalmazhatók” (1). Gyakorlatilag nincs olyan szakterület, ahol a gyógyszerek alkalmazása kikerülhető. A betegek nem egyformán reagálnak a gyógyszeres kezelésre, sőt, a nemkívánatos hatások kialakulási valószínűsége sem ugyanaz mindenkinél. Az eltéréseknek számos oka lehet, ezeket foglalja össze az 1. táblázat (2).
