THE SIGNIFICANCE OF EFL TEACHERS MOTIVATIONAL STRATEGIES IN SUPPORTING EVER-CHANGING CLASSROOM LEARNING DYNAMICS
Authors: Wijaya Kristian Florensio 
Published: January 2025

Too much concentration and attention hasÂ been givenÂ to the significant degree of professional development growth without focusing on cultivating more robust educational motivation among globalized EFL educators.Â To compensate for this previous research drawback, this small-scale library study attempted to profoundly investigate the extentÂ strongÂ motivation strategies can impart extensive support for worldwide EFL educationalists to induce more supportive and positive second language learning climates in the presence of heterogeneous learners. Thus, the researcher thematically analyzed the identical findings generated by 30 previous EFL teachersâ€™ motivational strategies studies.Â WithÂ the employment ofÂ a thematic analysis, the researcher could potentially yield more credible, relevant, and contextual research results sinceÂ conscientious data interpretations were iteratively appliedÂ before grouping theseÂ particularlyÂ generated findings intoÂ someÂ similar research theme categories.Â All these 30 previously published EFL teachersâ€™ motivational strategies studies were adaptedÂ from 2017 to 2024Â year.Â The lastÂ currentÂ 7Â years of published studies were theÂ topmostÂ priority to ensure the trustworthiness of all the thematically-subsumed research findings toÂ be in lineÂ with theÂ majorÂ specific topic forming in this library investigation.Â The thematically divided research results revealed that robust EFL teachersâ€™ motivational strategies significantly helped second language learners master the desired target language competencies and experience more enjoyable classroom learning climates.Â

Latar belakang. Perubahan proses pembelajaran pada masa pandemi menyebabkan mahasiswa perlu beradaptasi. Perubahan proses pembelajaran dari tatap muka menjadi daring dan hybrid serta paparan materi pembelajaran yang banyak, jadwal yang padat, dan perubahan lingkungan belajar dapat menyebabkan terjadinya academic burnout yang ditandai dengan kelelahan baik fisik maupun emosional, sinisme, dan menurunnya efikasi diri. Prevalensi burnout yang dialami mahasiswa bidang kesehatan mencapai 44,9% sehingga perlu ada resiliensi akademik dalam menghadapi tantangan pada proses pembelajaran. Tujuan. Menggali penyebab burnout akademik dan menilai hubungan resiliensi dengan burn-out akademik pada mahasiswa kedokteran di masa pandemi. Metode. Penelitian ini menggunakan pendekatan metode campuran. Tahap kuantitatif menggunakan desain cross-sectional yang melibatkan 105 mahasiswa kedokteran tahun kedua dari Fakultas Kedokteran Universitas Trisakti. Tahap ini dilanjutkan dengan tahap kualitatif menggunakan Focus Group Discussion dengan 26 mahasiswa yang mengalami burnout tingkat sedang hingga berat. Data resiliensi akademik diperoleh dari data sekunder yang dikumpulkan selama tes psikometrik untuk seleksi penerimaan mahasiswa. Burnout akademik diukur menggunakan kuesioner School Burnout Inventory versi Bahasa Indonesia yang telah divalidasi. Hasil. Sebanyak 62,5% mahasiswa mengalami burnout ringan dan hanya 4,8% yang tidak mengalami burnout. Mahasiswa yang mengalami burnout sedang - berat sebesar 32,7%. Kejadian burnout yang cukup tinggi memerlukan penanganan khusus agar tidak menjadi lebih berat. Resiliensi akademik tidak berhubungan secara statistik dengan burnout yang dialami (p>0.05). Kesimpulan. Mahasiswa kedokteran yang mengalami burnout sedang-berat sebanyak 32,7%.

Acute Generalized Exanthematous Pustulosis after Oral Antihistamine
Authors: Riva Hannah , Giandoni Martin , Celis Frank , Reyes Barron Cynthia 
Published: January 2025

Acute generalized exanthematous pustulosis (AGEP) is a cutaneous adverse reaction that may be severe. It is often caused by drug exposure, most commonly antibiotics; however, many others have been implicated. We present a case of hydroxyzine associated AGEP in a 34-year-old man taking the antihistamine for anxiety. The patient presented with a pruritic, erythematous rash on the extremities, trunk and neck. He was initially diagnosed with folliculitis, although Gram stain and culture were negative. With worsening rash, a punch biopsy was performed and showed subcorneal pustules filled with neutrophils, consistent with AGEP. Additional history led to the identification of the causative agent. Hydroxyzine was discontinued, and the patient’s symptoms improved. Although AGEP is usually self-limited, persisting for one to two weeks followed by desquamation, 17 percent of patients will have organ dysfunction and may require hospitalization. Clinicians should be prepared to recognize this potentially severe reaction, particularly when prescribing a new medication, including a common antihistamine, as in this rare case.

Authors: Terrell Maci , Rosen Theodore 
Published: January 2025

Background: Human Papillomavirus is a sexually transmitted infection in the United States with an estimated 40% prevalence.
Methods: This study assessed Google Trends data for genital warts related search terms from 2004 to 2023. The latest Centers for Disease Control-reported National Immunization Survey for 2022 were compared to Google Trends data for patterns or correlations.
Results: Average annual searches for genital warts decreased by 73.7% from 2004 to 2023 with the largest reduction (-23.14%) occurring between 2019 and 2020. West Virginia had the highest twenty-year average searches for genital warts related search terms (94), while Utah was found to have the lowest. Minnesota, Massachusetts and Washington were reported on top ten states with the highest HPV vaccination coverage ( ≥ 1 dose) also were found on top ten states with the lowest twenty-year average Google Trend search inquiries for genital warts. Conversely, West Virginia, South Carolina, Oklahoma, Kentucky and Mississippi were found to be on the top ten states with the lowest reported ≥ 1 HPV dose vaccination coverage and among top ten states with highest genital wart searches.
Conclusion: Google Trends data can help identify at-risk regions and guide efforts to improve HPV vaccination rates in the United States.

Introduction: We provide updated long-term safety data for lebrikizumab in adults and adolescents with moderate-to-severe atopic dermatitis (AD).
Methods: Integrated data from 11 phase 2/3 clinical trials were summarized in 2 datasets: 1) All-placebo-controlled Week 0-16 (All-PC; lebrikizumab 250 mg every 2 weeks [LEBQ2W] vs placebo); and 2) All-LEB (includes patients who received ≥1 dose of lebrikizumab any time during the 11 studies). All-PC includes phase 3 studies ADvocate 1 and 2, ADhere, ADhere-J, ADopt-VA, and ADvantage, and phase 2b KGAF; All-LEB includes phase 3 ADore and ADjoin and phase 2 Treble and KGAH, in addition to those in All-PC. Percentage and exposure-adjusted incidence rates (IR)/100 patient-years exposure are provided for All-PC and All-LEB, with study-size adjusted for All-PC.
Results: In All-PC, there were 719 patients (205.9 PYE) in the placebo group and 1251 (375.8 PYE) in the LEBQ2W group. All-LEB had 2415 patients (3167.8 PYE). In All-PC, the frequency of treatment-emergent adverse events (TEAEs) was similar between treatment groups; most were nonserious and mild/moderate in severity and did not lead to treatment discontinuation. Frequencies of SAEs were low in All-PC (placebo, 1.7%; LEBQ2W, 1.2%), and IR decreased with longer lebrikizumab exposure (IR LEBQ2W in All-PC, 3.9; IR All-LEB, 2.9). One death was reported in the placebo group in All-PC and 4 deaths in All-LEB (no deaths were considered related to the study drug by investigators). The most frequently reported TEAE (Preferred Terms) in All-PC was atopic dermatitis (12.8%) for placebo and conjunctivitis (7.1%) for LEBQ2W. In the placebo-controlled period, frequencies of the following AEs were: conjunctivitis cluster (placebo, 3.0%; LEBQ2W, 11.7%), injection site reactions (placebo, 1.6%; LEBQ2W, 2.9%); and herpes zoster (placebo, 0.1%; LEBQ2W, 0.4%). Skin infections were reported less frequently with lebrikizumab (placebo, 6.0%; LEBQ2W, 2.4%). The IRs of the AEs of special interest decreased (conjunctivitis cluster, injection site reactions) or remained stable (herpes zoster) with increased exposure years to lebrikizumab.
Conclusion: Results of this updated integrated safety analysis are consistent with previously reported data1 from the lebrikizumab clinical trial program. IRs of most TEAEs did not increase with longer duration of exposure to lebrikizumab in adolescents and adults with AD.

ADapt (NCT05369403), an open-label, Phase 3b, 24-week study, evaluated the efficacy and safety of lebrikizumab (LEB) in patients with moderate-to-severe atopic dermatitis (AD) previously treated with dupilumab (DUPI). Patients must have discontinued DUPI due to inadequate response (non-response, partial response, or loss of response), intolerance or an adverse event (AE), or other reasons. Four or more weeks after discontinuing DUPI, patients received a 500-mg LEB loading dose at Baseline and at Week 2 followed by 250 mg every 2 weeks through Week 16 (Q2W). At Week 16, responders (IGA 0 or 1 with ≥2-point improvement (IGA0,1) or EASI75 [primary endpoint]) received LEB 250 mg once every 4 weeks (Q4W); other patients continued with 250 mg Q2W. Q2W and Q4W data were pooled and analyzed as-observed and with nonresponder/multiple imputation (NRI/MI). Among 86 enrolled patients, 56% discontinued DUPI due to inadequate response, 16% due to intolerance/AEs to DUPI, and 28% for other reasons. For all patients, at Weeks 16 and 24, respectively, proportions of patients achieving: 1) EASI75: 57.4% and 60.0%, as-observed; 50.7% and 52.8% NRI/MI; 2) IGA0,1: 38.7% and 38.2%, as-observed; 35.6% and 36.8%, NRI/MI; 3) Face-IGA 0: 42% and 49%, as-observed; 4) Pruritus NRS ≥4-point improvement 53.2% and 61.5% as-observed; 48.8% and 47.9% NRI/MI; and 5) DLQI ≥4-point improvement 83.0% and 83.0% as-observed. The safety profile was consistent with other LEB Phase 3 trials. Four patients who discontinued DUPI due to conjunctivitis did not report conjunctivitis with LEB. 3.5% of patients reported treatment-emergent conjunctivitis. In DUPI-experienced patients, treatment of moderate-to-severe AD with LEB resulted in meaningful improvements in skin clearance, itch, and quality of life.

Published: January 2025

Introduction: Atopic dermatitis (AD) is a chronic, relapsing, heterogeneous inflammatory disorder. After a flare-up, the affected skin may have areas of post-inflammatory hyper- or hypo-pigmentation (PIH). A new scale, the PDCA-Derm™, assesses PIH by comparing post-inflammatory lesions to adjacent normal skin. This single-item clinician-reported outcome measure addresses a key gap in AD skin assessment. The primary objective of this study was to evaluate qualitative and quantitative data obtained from healthcare providers (HCPs) on the suitability of the PDCA-Derm for use in patients with moderate-to-severe AD.
Methods: HCPs recruited were dermatologists who treat patients with moderate-to-severe AD. During individual 60-minute cognitive debriefing meetings, each HCP was asked about their interpretation of the instructions and response options of the PDCA-Derm, and their opinion on its suitability to capture changes in PIH in patients with moderate-to-severe AD of all skin tones. Using a series of photos (n=22), HCPs assessed PIH using the PDCA-Derm at 2 timepoints. The intraclass correlation coefficient (ICC) was used to evaluate intra- and inter-rater reliability.
Results: Ten HCPs, all holding a Doctor of Medicine as their highest degree, participated in the study. The mean age of participants was 51.4 years (standard deviation: 13.7), and over half (n=6) were female. Most HCPs reported having 11 or more years of experience practicing in dermatology (n=8). Six HCPs reported that 26–50% of both their patients overall and those with AD were patients with skin of color. PDCA-Derm instructions and response options were correctly interpreted by all HCPs, and all reported the response options were distinct from one another. Seven HCPs indicated the PDCA-Derm was easy to use. Six HCPs indicated the PDCA-Derm could capture PIH, and 5 indicated it had the ability to capture changes to PIH in patients with moderate-to-severe AD. Intra-rater reliability was good to excellent (ICC=0.76–0.99, n=8) for all but 2 HCPs (ICC=0.55 and 0.74). The inter-rater reliability for PIH ranged from good at timepoint 1 (ICC=0.75, n=10) to excellent at timepoint 2 (ICC=0.90, n=10).
Conclusion: The PDCA-Derm was well understood by HCPs and had good inter- and intra-rater reliability, supporting its appropriateness for use to assess PIH in moderate-to-severe AD. Additional studies investigating HCP assessment of the PDCA-Derm and its reliability are needed to make solid conclusions about the instrument's validity.

Published: January 2025

Introduction
With a vision of a 90% reduction of grade 2 disability (G2D) in the Global Leprosy Strategy by 2030, the management of trophic ulcer, a common G2D, has become a priority. Autologous injectable perilesional platelet rich plasma (PRP) is first generation, whereas autologous platelet rich fibrin membrane (PRFM) is second generation platelet concentrate helping in trophic ulcer healing by providing growth factors and cytokines. PRFM requires less amount of blood (8 mL) against 20 mL in PRP.

Objectives
Evaluate the effectiveness and safety of PRFM with total contact cast versus PRP with total contact cast in leprosy trophic ulcer.

Methods
Observer-blind, non-inferiority randomised controlled trial recruited clinically diagnosed leprosy trophic ulcer with wound area measurement <40 cm2 after obtaining informed consent. Calculated sample size was 26 per group considering the percentage success in the control group (PRP) 39.29% and the experimental group (PRFM) 55.55%, 5% significance-level, 80% power, non-inferiority limit 10%, and 10% drop-out rate. Randomisation was done by computer generated random number table and allocation concealment by sequentially numbered opaque sealed envelope (SNOSE) technique. PRP was prepared with first spin 1,600 rpm for 10 minutes and second spin 4,000 rpm for 10 minutes. PRFM was prepared by centrifugation at 2,600 rpm for 3 minutes. Four treatment sessions followed by two follow-ups at 2 weekly intervals were conducted.

Results
Baseline clinico-demographic profile was similar in both groups. The surface area was significantly reduced (Friedman’s ANOVA P<0.001) in both PRP (from 422.48+657.30 sq cm to 247.84+635.96 sq cm) and PRFM (290.04+281.42 sq cm to 152.77+336.09 sq cm) with significant reduction from first FU onwards in both groups (Post-Hoc Dunn’s test P<0.001). Complete improvement was noted in 12% of PRP and 23% of PRFM (Fischer’s test P=0.465). Both groups showed improvement in DLQI.

Limitations
Short duration of treatment and follow-up (10 weeks).

Conclusion
PRFM with total contact cast is not inferior to PRP. Because of operational ease (less blood, less time), PRFM is a better alternative to PRP.
Cardiorespiratory responses to incremental exercise in dominant somatotypes
Authors: Jaiswal Kumar Nischay , Talwar Anjana , Bade Geetanjali Gokarn 
Published: January 2025

Objectives:
Somatotype rating is used to categorise human physiques using parameters related to body shape and composition. These parameters are adiposity, musculoskeletal robustness, and linearity. Somatotype rating is based on anthropometric dimensions that influence a person’s ability to perform physical activity. This study aimed to measure cardiorespiratory responses to incremental exercise in different somatotypes.

Materials and Methods:
Fifty (50) healthy male participants with a mean age of 24.10 ± 4.55 years were recruited in this study. The dominant somatotype was determined using the Heath and Carter method. Cardiopulmonary exercise testing was done to measure peak VO2, peak VO2/kg, metabolic equivalents (METS), breathing reserve (BR), minute ventilation (V.E), oxygen pulse (VO2/HR), and heart rate.

Results:
The cardiorespiratory parameters showed significant differences between the endomorphs and mesomorphs. Mesomorphs showed significantly higher peak oxygen consumption (mL/min) (2487 ± 364.3 vs. 2151 ± 287.8; P = 0.013) and exhibited significantly higher peak VO2 % predicted values (78.13 ± 10.11 vs. 66.92 ± 10.09; P = 0.003) than the endomorphs. METS % predicted was significantly higher in mesomorphs than endomorphs (78.13 ± 11.95 vs. 66.92 ± 10.09; P = 0.003). Similarly, the V.E (L) of mesomorphs was also higher than that of endomorphs (95.32 ± 18.63 vs 71.13 ± 25.39), but the BR (L) of mesomorphs was lower than endomorphs (38.38 ± 11.87 vs 53.80 ± 17.16) and ectomorphs (38.38 ± 11.87 vs 52.79 ± 9.47). Mesomorphs showed higher O2 pulse than endomorphs (14.8 [10.3–24.0] vs 12.8 [9.2–21.9]; P = 0.02); they also showed significantly higher respiratory frequency than endomorphs (1/s) (48.25 ± 11.34 vs. 38.19 ± 6.89; P = 0.001) and ectomorphs (48.25 ± 11.34 vs. 40.92 ± 7.03; P = 0.03).

Conclusion:
Cardiorespiratory responses to exercise vary among different somatotypes. Exercise capacity, as measured by VO2 peak, is higher in mesomorphs.
