Authors: Promnun Pattarapon , Panpong Kanokporn , Khlaipet Amonpong , Vilasri Veera , Khudamrongsawat Jenjit
Published: November 2023

The history of collecting and cataloging Thailand’s diverse herpetofauna is long-standing, with many specimens housed at the Thailand Natural History Museum (THNHM). This work aimed to assess the diversity of herpetofauna within the THNHM collection, ascertain conservation status of species, and track the geographical coverage of these specimens within the country. The THNHM collection boasts an impressive inventory, numbering 173 amphibian species and 335 reptile species. This collection reflects the substantial biodiversity within these taxonomic groups, rivaling the total number of herpetofauna species ever recorded in Thailand. However, the evaluation of their conservation status, as determined by the IUCN Red List, CITES, and Thailand’s Wild Animal Preservation and Protection Act (WARPA), has unveiled disparities in the degree of concern for certain species, possibly attributable to differential uses of the assessment criteria. Notably, the museum houses a number of type specimens, including 27 holotypes, which remain understudied. Sampling efforts have grown considerably since the year 2000, encompassing nearly all regions of the country. This extensive and systematic collection of diverse herpetofauna at the THNHM serves as a valuable resource for both research and educational purposes, enriching our understanding of these species and their significance in the broader context of biodiversity conservation.

Published: November 2023

The dispersion of chemical gases poses a threat to human health, animals, and the environment. Leaks or accidents during the handling of samples and laboratory materials can result in the uncontrolled release of hazardous or explosive substances. Therefore, it is crucial to monitor gas concentrations in environments where these substances are manipulated. Gas sensor technology has evolved rapidly in recent years, offering increasingly precise and reliable solutions. However, there are still challenges to be overcome, especially when sensors are deployed on unmanned aerial vehicles (UAVs). This article discusses the use of UAVs to locate gas sources and presents real test results using the SGP40 metal oxide semiconductor gas sensor onboard the Crazyflie 2.1 nano quadcopter. The solution proposed in this article uses an odor source identification strategy, employing a gas distribution mapping approach in a three-dimensional environment. The aim of the study was to investigate the feasibility and effectiveness of this approach for detecting gases in areas that are difficult to access or dangerous for humans. The results obtained show that the use of drones equipped with gas sensors is a promising alternative for the detection and monitoring of gas leaks in closed environments.

Authors: Liu Renbo , Ge Yuhui , Zuo Peng
Published: November 2023

To use different models for forecasting economic data suitably, three main basic models (the grey system model, time series analysis model, and artificial neural network (ANN) model) are analyzed and compared comprehensively. Based on the analysis results of forecasting models, one new hybrid intelligent model based on the ANN model and Harris hawks optimization (HHO) has been proposed. In this hybrid model, HHO is used to select the hyperparameters of the ANN and also to optimize the linking weights and thresholds of the ANN. At last, by using four economic data cases including two simple data sets and two complex ones, the analysis of the basic models and the proposed hybrid model have been verified comprehensively. The results show that the grey system model can suitably analyze exponential data sequences, the time series analysis model can analyze random sequences, and the ANN model can be applied to any kind of data sequence. Moreover, when compared with the basic models, the new hybrid model can be suitably applied for both simple data sets and complex ones, and its forecasting performance is always very suitable. In comparison with other hybrid models, not only for computing accuracy but also for computing efficiency, the performance of the new hybrid model is the best. For the least initial parameters used in the new hybrid model, which can be determined easily and simply, the application of the new hybrid model is the most convenient too.

(1) Background: The purpose of study was to compare the safety profile of glatiramer with natalizumab, alemtuzumab and ocrelizumab in pregnant and lactating women affected by multiple sclerosis (MS). (2) Methods: Individual case safety reports (ICSRs) were retrieved from the European spontaneous reporting system database (EudraVigilance). The reporting odds ratios (RORs) were computed to compare the reporting probability of events between natalizumab, alemtuzumab and ocrelizumab vs. glatiramer. (3) Results: A total of 1236 ICSRs reporting at least one DMT as a suspected drug were selected. More adverse drug reactions (ADRs) unrelated to pregnancy and breastfeeding (n = 1171; 32.6%) were reported than ADRs specific to pregnancy and breastfeeding (n = 1093; 30.4%). The most frequently reported unrelated ADR was MS relapse. Alemtuzumab and natalizumab seem to have a lower reporting probability of MS relapse compared to glatiramer (ROR 0.17, 95% CI 0.07–0.45 and ROR 0.34, 95% CI 0.20–0.57). Among pregnancy- and breastfeeding-related ADRs, the first most reported event was spontaneous abortion (n = 321; 8.9%). Natalizumab and ocrelizumab were associated with a higher reporting probability of spontaneous abortion compared to glatiramer (ROR 2.22, 95% CI 1.58–3.12; ROR 2.18, 95% CI 1.34–3.54, respectively), while alemtuzumab had a lower reporting frequency (ROR 0.32, 95% CI 0.17–0.60). (4) Conclusions: This study did not suggest any strong or new insights for DMTs in this special subpopulation. However, further studies need to be performed.

To realize simple and intelligent electrochemical ammonia (NH3) detection in water, highly dense colloidal copper nanoparticles (CuNPs) were prepared and subsequently deposited onto a glassy carbon electrode (GCE). The CuNPs/GCE was then placed in an oven at 60 °C to intelligently transform CuNPs into cuprous oxide (Cu2O) thin film. The colloidal CuNPs were characterized by ultraviolet-visible (UV-Vis) spectroscopy, whereas the fabricated Cu2O/GCE was subjected to Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and electrochemical impedance spectroscopy (EIS). The XRD of Cu2O/GCE showed the crystalline nature of the thermally converted Cu2O thin film, whereas XPS demonstrated that the thin film formed on the surface of GCE was primarily composed of Cu2O. The SEM images of Cu2O/GCE revealed Cu2O crystals with hexapod morphology. The EIS study exhibited substantially higher charger transfer activity of Cu2O/GCE compared to bare GCE. The drop coating of ammonia (NH3) solution onto Cu2O/GCE enabled the fabricated electrode to be utilized as an electrochemical sensor for NH3 detection in water. The cyclic voltammetric (CV) behavior of NH3/Cu2O/GCE was investigated in 0.1 M pH 7 phosphate buffer, which led to the formation of a copper-ammonia complex and revealed the nobility of the fabricated electrode. The square wave voltammetric (SWV) response was linear over the 10 µM and 1000 µM ranges with a detection limit of 6.23 µM and good reproducibility. The NH3/Cu2O/GCE displayed high selectivity for the detection of NH3 in the presence of various coexisting cations and anions in 0.1 M pH 7 phosphate buffer. The recovery of NH3 in the drinking water sample varied from 98.2% to 99.1%.
How Does Diagnostic Accuracy Evolve with Increased Breast MRI Experience?
Authors: Wu Tong , Alikhassi Afsaneh , Curpen Belinda
Published: November 2023

Introduction: Our institution is part of a provincial program providing annual breast MRI screenings to high-risk women. We assessed how MRI experience, background parenchymal enhancement (BPE), and the amount of fibroglandular tissue (FGT) affect the biopsy-proven predictive value (PPV3) and accuracy for detecting suspicious MRI findings. Methods: From all high-risk screening breast MRIs conducted between 1 July 2011 and 30 June 2020, we reviewed all BI-RADS 4/5 observations with pathological tissue diagnoses. Overall and annual PPV3s were computed. Radiologists with fewer than ten observations were excluded from performance analyses. PPV3s were computed for each radiologist. We assessed how MRI experience, BPE, and FGT impacted diagnostic accuracy using logistic regression analyses, defining positive cases as malignancies alone (definition A) or malignant or high-risk lesions (definition B). Findings: There were 536 BI-RADS 4/5 observations with tissue diagnoses, including 77 malignant and 51 high-risk lesions. A total of 516 observations were included in the radiologist performance analyses. The average radiologist’s PPV3 was 16 ± 6% (definition A) and 25 ± 8% (definition B). MRI experience in years correlated significantly with positive cases (definition B, OR = 1.05, p = 0.03), independent of BPE or FGT. Diagnostic accuracy improved exponentially with increased MRI experience (definition B, OR of 1.27 and 1.61 for 5 and 10 years, respectively, p = 0.03 for both). Lower levels of BPE significantly correlated with increased odds of findings being malignant, independent of FGT and MRI experience. Summary: More extensive MRI reading experience improves radiologists’ diagnostic accuracy for high-risk or malignant lesions, even in MRI studies with increased BPE.

Hydatid cysts have been widely recognized for decades as a common medical problem that affects millions of people. A revolution in medical treatment may be on the prospect of nanotechnology enhancing chemotherapy against hydatid cysts. An overview of nanotechnology’s impact on chemotherapeutics is presented in the current review. It discusses some of the challenges as well as some of the opportunities. The application of nanotechnology to enhance chemotherapy against hydatid cysts is what this review will explore. Nanotechnology is a critical component of delivering therapeutic agents with greater precision and efficiency and targeting hydatid cysts with better efficacy, and minimizing interference with surrounding tissue. However, there are biodistribution challenges, toxicity, and resistance problems associated with nanotherapeutics. Additionally, nanobiosensors are being investigated to enable the early diagnosis of hydatid cysts. A nanobiosensor can detect hydatid cysts by catching them early, non-invasively, rapidly, and accurately. The sensitivity and specificity of diagnostic tests can be enhanced with nanobiosensors because they take advantage of the unique properties of nanomaterials. By providing more precise and customized treatment options for hydatid cysts, nanotechnology may improve therapeutic options and strategies for diagnosing the disease. In conclusion, treatment with nanotechnology to treat hydatid cysts is potentially effective but presents many obstacles. Furthermore, nanobiosensors are being integrated into diagnostic techniques, as well as helping to diagnose patients earlier and more accurately.

El Alzheimer como experiencia de aprendizaje de la filosofía
Authors: Rozo Martínez Anamaria
Published: November 2023

Partiendo del reconocimiento de la alteridad y heterogeneidad como parte constitutiva de la sociedad, se encuentra en la educación inclusiva una manera de construir condiciones para hacer posible la integración de lo diverso. El aprendizaje de la filosofía no escapa a este gran reto, adquiriendo relevancia la pregunta por sus sentidos y dinámicas en un caso con una persona con una deficiencia cognitiva como el Alzheimer, en el que se toma el contexto familiar como un espacio pedagógico desde el que se proponen estrategias que respondan a las necesidades de inclusión. Se utiliza entonces la fotografía como estrategia hermenéutica para comprender la perspectiva del “otro” e interpretarla por medio de la creación de obra. Este proceso de apropiación lleva a una reflexividad y autocomprensión que termina por transformar, tanto la relación cuidadora-adulto mayor, como los conceptos de los sujetos implicados, volviendo, efectivamente, toda esta experiencia en general, una oportunidad de aprendizaje filosófico.

Authors: Ramos-Ruiz Juan Andrés , Pérez-Milena Alejandro , Noguera-Cuenca Carmen , Rodríguez-Bayón Antonina , Ruiz-Díaz Beatriz
Published: November 2023

Background

Effective communication with GPs (General Practitioners) enables higher rates of patient satisfaction and adherence to treatment plans. People with severe mental illness (SMI) and their caregivers present unique characteristics that present difficulties in the GP–carer–patient communication process.

Aim

To explore the expectations of patients with SMI and their caregivers regarding GPs’ communication skills in primary care consultations.

Design & setting

Face-to-face interviews, using focus group methodology, which were undertaken in southern Spain.

Method

Forty-two participants took part in 21 paired semi-structured interviews with an average duration of 19±7.2 minutes. Information was audio-recorded and transcribed verbatim. Qualitative content analysis was undertaken, obtaining a codification in categories by means of triangulation.

Results

Four themes emerged from the analysis. Theme 1 was interviewer communication characteristics. The ability of GPs to use a language that was colloquial and adapted to each person was perceived as a determinant of the quality of care provided. An empathetic attitude, low reactivity, and efficient time management were the most valued communication skills. Theme 2 was telemedicine: telephone consultation and video consultation. The telephone consultation was perceived as a useful tool to care for people with SMI. Video consultation was valued as a requirement in isolated rural areas. Theme 3 was the role of the caregiver during the clinical interview. The caregiver was considered by the patients as an ally who improves the clinical interview. Theme 4 was the perceived barriers and facilitators during the clinical interview. The continuity of care, defined by a low turnover of GPs, determined the quality perceived by those who required care.

Conclusion

Themes emerging from this study have suggested that people with SMI require an inclusive, collaborative, and personalised approach in the care they receive from the public health system. Improved communication between GPs and patients with SMI is an essential requirement for quality medical care.

Published: November 2023

Avian Influenza H5N1 memiliki patogenisitas tinggi (HPAI H5N1) yang telah diketahui menginfeksi hewan dan manusia.  Ciri utama Avian Influenza  yaitu memiliki protein hemaglutinin. Protein hemaglutinin mempunyai kemampuan mengaglutinasi sel darah merah. Berdasarkan kemampuan protein tersebut, maka dapat dilakukan uji hemaglutinasi. Aktifitas protein hemaglutinin dapat dipengaruhi oleh suhu dan masa inkubasi. Pada uji hemaglutinasi dibutuhkan sel darah merah sebagai reseptor pengikatan protein hemaglutinin. Selain sel darah merah ayam sebagai reseptor, sel darah merah manusia golongan O juga dapat dijadikan sebagai reseptor bagi protein hemaglutinin. Avian influenza H5N1 mengenali asam sialat α-2,3-galaktosa pada unggas, sedangkan pada manusia mengenali asam sialat α-2,6-galaktosa yang terdapat pada permukaan sel darah merah.

Laju Endap Darah (LED) merupakan pemeriksaan untuk mengukur proses pengendapan sel darah merah dalam spesimen darah dengan satuan millimeter per jam (mm/jam). International committee for Standardization in Haematology (ICSH) merekomendasikan metode Westergren dan antikoagulan natrium sitrat sebagai Gold Standard dalam pemeriksaan laju endap darah. Nilai pemeriksaan laju endap darah dapat dipengaruhi banyak faktor diantaranya suhu ruangan, suhu rata-rata di Jawa Barat 18oC dengan suhu tertinggi 32oC, masih banyaknya fasilitas pelayanan kesehatan yang belum memperhatikan suhu ruangan optimal dalam pemeriksaan laboratorium khususnya LED.  Selain itu, lama simpan juga dapat berpengaruh dalam pemeriksaan LED, oleh sebab itu sebaiknya Pemeriksaan laju endap darah harus segera diperiksa setelah pengambilan darah dilakukan. Penelitian ini bertujuan untuk mengetahui ada tidaknya pengaruh suhu ruangan dan lama simpan darah sitrat terhadap nilai laju endap adrah metode westergren. Jenis penelitian yang digunakan adalah quasi experiment (eksperimen semu) dengan desain penelitian rancangan acak kelompok (RAK), dengan memberikan variasi suhu ruangan 18oC dan 28oC dan memberikan perlakuan lama simpan darah sitrat selama segera, 2 jam, dan 3 jam, kemudian dilakukan pemeriksaan Laju Endap Darah (LED) metode Westergren. Data  hasil penelitian yang didapatkan dianalisis secara statistik menggunakan uji General Linear Model (GML)- Repeated Measure. Berdasarkan hasil uji statistik dapat disimpulkan bahwa tidak terdapat pengaruh suhu ruangan dan lama simpan darah sitrat terhadap nilai laju endap darah metode westergren (p>0,05).

Kecacingan masih menjadi salah satu masalah kesehatan di Indonesia dan di belahan dunia lain. Sulitnya penanganan kecacingan karena kurangnya edukasi mengenai pemberian obat cacing, hidup bersih, dan pemeriksaan kecacingan secara merata pada seluruh penduduk. Salah satu cara pemeriksaan telur cacing yang menjadi gold standard adalah pemeriksaan langsung dengan pewarnaan eosin 2%. Eosin memiliki karakteristik warna berwarna merah, yang akan memberi warna merah pada latar belakang, dan keemasan pada permukaan telur cacing. Terdapat zat organik yang memilki warna sama dengan eosin 2% yaitu zat antosinanin, zat ini akan berwarna merah dalam suasana asam. Zat antosianin terdapat cukup tinggi pada daun tanaman jati (Tectona grandis). Tujuan dari penelitian ini adalah mengetahui efektivitas pewarnaan telur cacing Soil Transmitted Helminth (STH) dengan memanfaatkan daun jati (Tectona grandis). Penelitian ini bersifat eksperimental, dengan variasi jenis pelarut dalam ekstraksi yaitu ethanol 96% dengan penambahan HCl pekat, aquades dengan penambahan HCl pekat, yang kemudian akan dibandingkan dengan eosin 2%. Pembuatan ekstrak dilakukan 1x24 jam dengan menggunakan simplisia daun jati (Tectona grandis) dan ekstrak digunakan sebagai pewarna langsung pada sediaan feses dengan pengulangan sebanyak tiga kali. Pengamatan dilakukan secara mikroskopis untuk dilihat kejernihan, kejelasan lapang pandang dan telur cacing. Hasil data dianalisis dengan uji non-parametrik Kruskal-Wallis. Kesimpulan pada penelitian ini adalah pewarnaan dengan ekstrak daun jati (Tectona grandis) dengan pelarut ethanol 96% dengan penambahan HCl pekat, aquades dengan penambahan HCl pekat dan eosin 2% memberikan hasil tidak signifikan (p>0.05).

Pemeriksaan histopatologi merupakan alat diagnostik yang sangat penting untuk identifikasi organisme infeksius. Bagian penting dalam mencapai diagnosis yang benar yaitu gross examination. Ukuran pemotongan jaringan saat gross examination tergantung pada arah pisau yang digunakan saat pemotongan. Arah pisau yang digunakan pada penelitian ini yaitu melintang dan membujur. Jaringan yang dipotong secara melintang dengan jaringan yang dipotong secara membujur akan menghasilkan gambaran yang berbeda pada preparat. Penelitian ini bertujuan untuk mengetahui pengaruh ukuran dan arah pemotongan jaringan terhadap kualitas preparat jaringan payudara menggunakan metode kuasi eksperimen yang membandingkan kelompok membujur (eksperimen) dengan kelompok melintang (kontrol) untuk diteliti. Sampel yang digunakan pada penelitian adalah jaringan payudara yang dibuat menjadi 24 preparat dari 4 blok yaitu melintang 2 x 2 x 0,3 cm, membujur 2 x 2 x 0,3 cm, melintang 3 x 2 x 0,5 cm dan membujur 3 x 2 x 0,5 cm. Indikator penilaian yang digunakan adalah kualitas preparat berupa nilai kontras warna inti sel dan sitoplasma serta kejelasan batas membran sel lemak. Hasil penelitian menunjukan bahwa preparat membujur 2 x 2 x 0,3 cm memiliki kualitas yang paling baik. Saran penulis adalah perlu dilakukan pembuatan standar nilai OD inti sel dan sitoplasma.
