A mixed methods, longitudinal study: characterizing the differences in engagement and perceived learning of medical students in online and in-person team-based learning classes
Authors: Lee Irene Cheng Jie , Wong Peiyan
Published: July 2023

Background: The rapid transition to online delivery of medical curriculum has facilitated the continuation of medical education during the COVID-19 pandemic. Whilst active learning approaches, including Team-Based Learning (TBL), are generally more supportive of the learner’s needs during such transition, it remains elusive how different learning environments affect a learner’s motivation, engagement, and perceived learning over a prolonged period. We leveraged on Self-Determination Theory (SDT) and key learners’ characteristics to explore the levels of student’s engagement and perceived learning in two TBL learning environments, online and in-person, over an extended period. We hypothesize that students’ self-reported perceptions of engagement and learning will be lower in online compared to in-person TBL classes.

Methods: This is a mixed methods study with 49 preclinical graduate medical students completing the same questionnaire twice for each learning environment, online TBL and in-person TBL, over an eight-month period. Quantitative data were collected on learners’ characteristics, basic psychological needs satisfaction, motivation, student’s engagement and perceived learning. The final questionnaire also explored participants’ perception on which learning environment better supported their learning.

Results: We found that autonomy support, perceived competence and needs satisfaction, and perceived learning were higher in-person than online. Additionally, most learners felt that in-person TBL was better for learning, as the concepts of learning space and the community of practice were mediated by being in-person.

Conclusions: TBL, being an active instructional method, can maintain students’ engagement because it supports many aspects of SDT constructs and perceived learning. However, online TBL is unable to fully support the students’ needs and perceived learning. Hence, we strongly advocate for any in-person opportunities to be included in a course, as in-person classes best supports students’ engagement and perceived learning.

Names of Person by Occupation in Modern Communication (productivity and Regularity of Semantics and Form in Word-formation)
Authors: Shaposhnikov Vladimir
Published: July 2023

The names of person by activity kind and correlative forms of feminine gender are considering. In word-formation as unit realm in their analogic-individual connections, individuality of words by these connections is slackening, and regular, standard facts at head role move out. The means of expressing the word-formative meaning is not only the affix, but its combination with a certain circle of underlying stems. Typical properties don’t exist out of semantic connection with the individual properties, and the individual don’t dissolve in the typical. In Russian word-formation there are the regular systematic occurrences, and irregular nonsystematic ones. Systemic phenomena in a functioning language are interrupted by asystemic ones. The products of word-building activity are generated by certain mechanisms.

On the other hand, word-building products undergo structural processing and are accepted or not accepted by the language system and communicative practice. All basic models of name of person by activity kind and nomination of gender accordance in contemporary Russian language, their place in the system of language is revealing.

Introduction: Exposure to UV radiation promotes skin damage, photoaging and photocarcinogenesis. Photoprotection reduce the negative effects of ultraviolet rays. However, ultraviolet light has some beneficial effects like the production of vitamin D. It is also used in the treatment of some skin diseases.
Aim of the study: The aim of the study was to assess the knowledge of medical students and non-dermatology physicians on the harmful and beneficial effects of UV radiation and photoprotection.
Materials and methods: The research material was collected using an anonymous online survey. The obtained results were analyzed and verified on the basis of scientific literature and statistically processed using Microsoft Office Excel.
Results: 95.3% of respondents believe that knowledge about the effects of radiation is important in medical practice and 98.8% can name at least one skin cancer whose risk factor is UV radiation. All of respondents believe that UVR affects the aging of the skin. 77.8% of respondents know the meaning of the term "SPF". 81.9% are aware that UVB radiation affects the synthesis of vitamin D and 72.0% can indicate at least two dermatoses in which phototherapy is used.
Conclusion: Medical students and doctors have a lot of knowledge about the effects of UV radiation and it is important in their medical practice. Increasing awareness about radiation, forms of sun protection and a more thorough physical examination can have a significant impact on patient health. Great vigilance and noticing a suspicious change accelerates the start of treatment and determines the success of the therapy.
Historia Polskiego Wydziału Lekarskiego przy Uniwersytecie w Edynburgu, 1941-1949. Nowa perspektywa badawcza
Authors: Palacz Michał Adam
Published: July 2023

Artykuł przedstawia wyniki wieloletnich badań nad historią Polskiego Wydziału Lekarskiego (PWL) przy Uniwersytecie w Edynburgu. W odniesieniu do istniejącej literatury przedmiotu, w której ta założona w czasie II wojny światowej uczelnia prezentowana jest zarówno jako instytucja bez precedensu w historii świata jak i kontynuacja przedwojennych polskich uniwersytetów, niniejsza praca proponuje spojrzenie na ten temat z perspektywy historii emigracji przymusowej z kontynentalnej Europy w pierwszej połowie XX w. Nieznane wcześniej fakty na temat powstania i likwidacji PWL przedstawiono w szerszym kontekście zmieniających się postaw wobec lekarzy-uchodźców w Wielkiej Brytanii. Ponadto podkreślono transnarodowy charakter PWL i kluczową rolę, jaką w jej powstaniu odegrały kompetencje transkulturowe naukowców, takich jak Francis Crew i Antoni Jurasz. Wreszcie zasugerowano, że kreatywne połączenie polskich i szkockich programów i metod nauczania w czasie studiów medycznych na PWL ułatwiło po wojnie integrację polskich lekarzy- -uchodźców nie tylko w Wielkiej Brytanii, lecz również w innych krajach osiedlenia, takich jak USA, Kanada, Australia czy Nowa Zelandia.

Polscy pionierzy chirurgii wątroby. Nowe odkrycia
Authors: Zamachowska Monika
Published: July 2023

Temat polskich pionierów chirurgii wątroby był już analizowany przez historyków medycyny. Wśród nazwisk polskich lekarzy zdecydowanie najczęściej pojawia się Julian Pęski, ze względu na zastosowaną przez niego nową technikę szycia, która zrewolucjonizowała zabiegi operacyjne w zakresie tego narządu. Szew Pęski-Kuzniecow (Pensky-Kuznetsoff) jest do tej pory stosowany we współczesnej chirurgii. Wspomina się też nazwisko Rewolińskiego, który w 1895 r. zaopatrzył pourazowe uszkodzenie wątroby. Nieznane są zasługi innych XIX wiecznych lekarzy: Hipolita Oderfelda, Romana Jasińskiego i Jakóba Rosenthala. Celem artykułu jest przedstawienie nieznanych polskich pionierów chirurgii wątroby, w szczególności Jakóba Rosenthala, chirurga, który jako pierwszy w Polsce i jeden z pierwszych w Europie wykonał resekcję guza nowotworowego wątroby.

Authors: Początek Michał
Published: July 2023

Tematem artykułu jest analiza „Słownika lekarzów polskich” pod kątem obecności kobiet zajmujących się opieką zdrowotną (nie tylko lekarek) do XIX wieku włącznie. Dzieło przygotowane przez lekarza, historyka i bibliografa, Stanisława Kośmińskiego wydane drukiem w Warszawie w roku 1888, zawiera wykaz prac zarówno lekarzy polskich, jak i cudzoziemców, którzy praktykowali na ziemiach polskich, albo tu wydawano ich publikacje. Wydawnictwo jest tym bardziej cenne, że umieszczono w nim wszystkie pozycje od okresu średniowiecza, które udało się autorowi odnaleźć. Podano też krótkie informacje o autorach. Celem Kośmińskiego było bowiem zebranie i przedstawienie dorobku polskiej medycyny w sytuacji ograniczonej możliwości dalszego rozwoju nauk medycznych z powodu braku własnej państwowości i pod zaborami.

Authors: Początek Michał
Published: July 2023

Celem pracy jest przybliżenie charytatywnej działalności kościoła katolickiego w północnej Wielkopolsce w okresie kontrreformacji. Zorganizowano wówczas, nie tylko tutaj, liczne przytułki dla chorych i ubogich, co stanowić miało świadectwo pokory i miłosierdzia oraz przeciwwagę wobec protestanckich zarzutów dotyczących pychy i chciwości kleru. W oparciu o drobiazgowe sprawozdania okresowych wizytacji parafii przez biskupów, na przykładzie Piły i okolic, podjęto próbę oceny ważnej funkcji spełnianej przez Kościół w zakresie opieki społecznej i lecznictwa w XVII i XVIII wieku.

Shockwave versus ultrasound therapy in the enhancement of Aloe vera in cutaneous wound healing
Authors: Mahran Hesham Galal
Published: July 2023

Objective:

To investigate the healing efficacy of topical Aloe vera enhanced by shockwave or ultrasound therapy on wounds in rats and compare both effects.

Method:

A total of 75 male albino rats were randomly divided into equal groups A, B, C, D and E. Under anaesthesia, a wound (6cm2) was created on the back of each rat. Group A received topical Aloe vera under occlusive dressing followed by shockwave therapy with the following parameters: 600 shocks, four pulses/second and 0.11mJ/mm2. Group B received topical Aloe vera under occlusive dressing followed by therapeutic ultrasound with the following parameters: pulsed mode, 2:8 duty cycle, 1MHz and 0.5 W/cm2. Group C received the same treatment as group A but in a reversed sequence—the shockwave therapy followed by the Aloe vera gel. Group D received the same treatment as group B but in a reversed sequence—therapeutic ultrasound followed by the Aloe vera gel. And control group E only received topical Aloe vera under occlusive dressing. Each group received three sessions per week, for two weeks. Wound extent and shrinkage rates were measured at study initiation and at the end of each week.

Results:

There were significant wound reductions in groups A and B compared to C and D, respectively, and in group A compared to group B.

Conclusion:

Shockwaves and ultrasound were found to amplify the effect of the Aloe vera on the wound, and there was improved wound healing in the shockwave group A compared to the ultrasound group B.

Background: Spinal Tuberculosis (TB) is one of the significant health dangers that affect the general wellbeing of an individual. It is one of the most common form of extra pulmonary tuberculosis that affects the general population. Diagnosis of tuberculosis is done using an array of techniques. The present study has compared the efficacy of these tests used for detecting the spinal TB in biopsy samples. Material and Methods: The study was conducted on patients who suffered from spondylodiscitis and with biopsy proven spinal TB by one of the following tests and were treated in the study center. The study included a total of 150 patients with spinal TB who visited the department for further treatment. The biopsy samples of these patients were then processed for Line probe assay (LPA), Gene Xpert, liquid culture (bactec MGIT) followed by gram staining and fungal staining, and histopathological examination. Result: In this study total of 150 patients were included who had ages ranging from 16-77 years with 93male and 57 female patients. When the study results were compared Gene Experts showed a 100% sensitivity and 80% of specificity. When we compared the histopathology results with gene expert, we get a sensitivity of 16.7% and specificity of 50%. Gram stain with the sensitive gene expert, the sensitivity is 45.5% and specificity is 25%. Similar analysis was done with sensitive gene and now with the resistant gene to identify their sensitivity was 0% and the specificity was at 42.9%. Gram stain when correlated with gene, the sensitivity came out to be 9.1% and specificity at 25%. Fungal stain with resistant gene, when correlated, sensitivity comes to 9.1% and specificity is at 0%. Conclusion: This study showed that for detection of tuberculosis rather than relying on only single technique it should be done with a combination of techniques.

Published: July 2023

Introduction Os-odontoideum is a rare condition, described radiographically and clinically as a congenital anomaly of the second cervical vertebra (axis), it a smooth, independent ossicle of variable size and shape separated from the base of a shortened odontoid process by an obvious gap, with no osseous connection to the body of C2. Material and methods This study reviewed the literature on OO to evaluate its etiology, the clinical presentations, differential diagnosis, imaging modalities and outcomes in the management of asymptomatic and symptomatic cases of os odontoideum. PubMed, EMBASE, Google Scholar and Cochrane key articles were searched. Discussion Considering etiology traumatic hypothesis is favoured over congenital hypothesis as per recent literature on OO. Clinical presentation varies from asymptomatic to mild neck pain to severe myelopathy and neurodeficit. Various C1-C2 instrumentation and fusion techniques like wiring, trans articular screw and laminar screws have been described with good success rates. Conclusion Os odontoideum is a rare condition with limited existing literature. Considering significant risks involved if conservative management is opted like severe neurodeficit to sudden death on trivial trauma and the recent improvement of imaging tools helping to understand the pathology of the disease, surgery can be indicated even in an incidentally detected os odontoideum. Although for asymptomatic stable patients’ individual case-by-case approach can be considered depending on factors such as age, activity level, comorbidities, syndromic association and radiographic findings.

Published: July 2023

Management of sacral fractures with neurological deficits has been a topic of debate. Literature is divided between conservative and operative management. We report a case of a 32-year-old male with post-traumatic unstable complex transverse sacrum fracture and associated stable pelvic ring fractures with loss of bowel and bladder control. He had a fall from the second floor over the buttocks. Plain lateral radiography showed a transverse sacral fracture located between S2 and S3 with kyphosis at the fracture site. MRI showed a compromised canal due to a large retro pulsed fragment pressing over the anterior aspect of sacral roots. Thorough decompression of cauda equina and sacral roots was performed, and sacral ala fracture was fixed with two percutaneous 6.5 mm cannulated cancellous Ilio-sacral screws and two 3.5 mm recon locking plates were applied for the sacrum. The patient regained his bladder control 3 months after the surgery and bowel control 4 months after the surgery. At the end of 1 year, the patient has persistent saddle anaesthesia but good bowel and bladder control. Early decompression and stabilization of unstable complex sacrum fractures with neurological compromise can facilitate optimum neurological improvement and favourable clinical outcomes in terms of early mobilization and pain relief.

Introduction: Microtubular decompression (MTD) being a short-duration surgery, with many advantages, has gained popularity and can be done either in general anaesthesia (GA) or awake techniques like spinal anaesthesia (SA). The authors ventured to assess perioperative parameters, quantify peri-operative complications as the primary aim and determine patient satisfaction as the secondary aim of the study. Materials and Methods: It was a retrospective study performed over a period of ten years (2009–2019) and included 625 patients. The patients included were aged greater than 18 years, American Society of Anaesthesiologists (ASA) score 1, 2, or 3. Patients with ASA 4 or 5, spinal instability, infection, or revision surgeries were excluded. Results: There is no significant difference in the complication rates. The clinical outcome in the form of VAS and ODI scores showed significant differences both in SA and GA groups at the final follow-up. The total anaesthetic, surgical times, mean arterial pressure (MAP), and heart rate (HR) perioperatively were longer in the GA group (P < 0.05). The perioperative blood pressures are lower in the SA group. The dissatisfaction rate is about 3.5%, of which the patients and a total of 88.5% of patients would like to opt for SA for future surgeries. Conclusion: This study represents the ten-year experience with MTD operated either with SA or GA. Awake spinal surgery is promising and has the glaring benefits of better peri-operative hemodynamic stability, and faster recovery with reduced surgical and anaesthetic duration. Dissatisfaction rates can be decreased by better explanation and the patient’s decision.

Open EDFA gain spectrum dataset and its applications in data-driven EDFA gain modeling

Published: July 2023

Optical networks satisfy high bandwidth and low latency requirements for telecommunication networks and data center interconnection. To improve network resource utilization, machine learning (ML) is used to accurately model optical amplifiers such as erbium-doped fiber amplifiers (EDFAs), which impact end-to-end system performance such as quality of transmission. However, a comprehensive measurement dataset is required for ML to accurately predict an EDFA’s wavelength-dependent gain. We present an open dataset consisting of 202,752 gain spectrum measurements collected from 16 commercial-grade reconfigurable optical add–drop multiplexer (ROADM) booster and pre-amplifier EDFAs under varying gain settings and diverse channel-loading configurations over 2,785 hours in total, with a total dataset size of 3.1 GB. With this EDFA dataset, we implemented component-level deep-neural-network-based EDFA models and use transfer learning (TL) to transfer the EDFA model among 16 ROADM EDFAs, which achieve less than 0.18/0.24 dB mean absolute error for booster/pre-amplifier gain prediction using only 0.5% of the full target training set. We also showed that TL reduces the EDFA data collection requirements on a new gain setting or a different type of EDFA on the same ROADM.

Self-homodyne detection (SHD) is a promising approach to realize high-capacity short-reach optical transmission systems with low cost and low power consumption. We experimentally demonstrate single-carrier net 800-Gb/s SHD transmission with low-cost ∼MHz linewidth distributed feedback (DFB) laser over 2 km, 10 km, 25 km, and 40 km single-mode fiber (SMF) using three different quadrature amplitude modulation (QAM) formats, including 80-Gbaud dual-polarization (DP) 64QAM, 100-Gbaud DP-32QAM, and 120-Gbaud DP-16QAM. Among them, net 800-Gb/s DP-64QAM SHD transmission over 25 km SMF using an uncooled DFB laser with a linewidth of 2.6 MHz is experimentally verified. The detailed experimental performance evaluation of net 800Gb/s SHD system is performed, in which various configurations are considered, such as different laser linewidths, three QAM formats, and different transmission distances. DFB lasers with linewidths of 1 MHz and 2.6 MHz lead to negligible penalty when compared to the same SHD system but using an external cavity laser (ECL) with a linewidth of 26kHz in back-to-back (BTB) case. 80-Gbaud DP-64QAM obtains the highest optical signal-to-noise ratio (OSNR) requirement and the highest bit-error rate (BER) floor but the best tolerance of chromatic dispersion (CD). 120-Gbaud DP-16QAM achieves the lowest OSNR requirement and the lowest BER floor but the worst tolerance of CD. The detailed experimental investigation is conducive to promote the practical application of SHD in different short-reach scenarios.
Handheld common-path swept-source optical coherence tomography angiography
Authors: Chang Yu-Huan , Chen Chen-Yi , Kuo Wen-Chuan
Published: July 2023

This study develops a handheld optical coherence tomography angiography (OCTA) system that uses a high-speed (200 kHz) swept laser with a dual-reference common-path configuration for stable and fast imaging. The common-path design automatically avoids polarization and dispersion mismatches by using one circulator as the primary system element, ensuring a cost-effective and compact design for handheld probe use. With its stable envelope (i.e., sub-µm shifts) and phase variation (corresponding to nm changes in axial displacement), the minimum detectable flow velocity is ∼ 0.08 mm/s in our experiment, which gives the common-path setup a high potential for application in a handheld OCTA system for clinical skin screening. In vivo skin structures and microvasculature networks on the dorsum of the hand and cheek of a healthy human are imaged successfully.

Published: July 2023

The Rydberg atomic receiver, sensing microwave electric field with high sensitivity and broad bandwidth, possesses the potential to be the staple for precise navigation and remote sensing. In this Letter, a Ku-band three-dimensional location system using an L-shaped array of Rydberg atomic receivers is theoretically proposed and experimentally demonstrated, and the proof of principle results show excellent consistency between the location-derived and the setting coordinates. The novel L-shaped array, together with the triangulation method, gives both phase difference and angle of arrival, achieving location of the horn for a signal microwave field in three-dimensional space. The concluded validity of this location system in the testing scene remains at approximately 90% with a theoretical maximum location tolerance of 5.7 mm. Furthermore, the estimation of two different spatiotemporal coordinates for the moving target confirms the velocity measurement capability of the system with errors less than 0.5 mm/s. The proposed location system using a Rydberg atomic receiver array is a verification for the most basic element and can be extended through repetition or nesting to a multi-input–multi-output system as well as multi-channel information processing.
