Catalyst-free Approach to Dihydropyrimidones Using Glycerol/Ethyl
Lactate as a Recyclable and Biodegradable Promoting Medium
Authors: Kushwaha Smriti , Singh Swastika , Baranwal Jyoti , Jyoti Archana 
Published: February 2024

Abstract:
A variety of dihydropyrimidone compounds were synthesised using an effective one-pot,
multicomponent, environmentally friendly reaction of aromatic aldehydes, urea/thiourea, ethyl acetoacetate,
and glycerol/ethyl lactate. To the best of our knowledge, this is the first catalyst-free strategy
for the synthesis of this key scaffold with medicinal chemistry applications. Other significant aspects
of the current approach consist of the employment of glycerol/ethyl lactate as a biodegradable and
environmentally friendly reaction medium-cum-promoter, the use of easily available substrates, moderate
reaction conditions, ease of use, a wide substrate scope, a short reaction time, easy workup, and
excellent yields, and atom efficiency, which make the disclosed procedure an excellent alternative to
existing methods.

Published: February 2024

Objective::
To investigate the influence of improved exposure parameters on the image quality of multi-slice spiral computed tomography in nasal bone
fracture imaging

background:
The evaluation of the reliability and accuracy of CT images is one of the most important problems that affect medicine at present. The image quality is decided by the performance of the whole imaging system, and the choice of CT scanning parameters also affects the image quality.

Methods::
Fifty patients with optimised parameters combined with coronal scanning were allocated to the modified group and 50 patients with routine
scanning parameters to the routine group. The image quality and nasal bone display of the two groups were assessed and statistically analysed, and
the quality of scanned images before and after parameter optimisation was compared.

Results::
The optimised image quality was better than that of conventional scanning parameters. The parameters used were 120 kv, 180 mA, a layer
thickness of 0.625 mm, a layer spacing of 0.312 mm, a pitch of 0.516:1, a frame speed of 1 s, a scanning field of 12 cm and a reconstructed layer
thickness for scanning of 0.625 mm; the scanned image was clear, and the parameter optimisation was achieved. This ensures that the annotation
data in ITK labelling is more accurate.

Conclusion::
The optimised parameters and scanned coronal plane show the nasal bone and its surrounding structures more comprehensively, which is of high
diagnostic value for nasal bone fractures. The three-dimensional annotation data based on ITK is more standardised, laying a foundation for the
subsequent research of artificial intelligence modelling.
Three-Day Monitoring of Adhesive Single-Lead Electrocardiogram Patch for Premature Ventricular Complex: Prospective Study for Diagnosis Validation and Evaluation of Burden Fluctuation
Authors: Ahn Hyo-Jeong , Choi Eue-Keun , Lee So-Ryoung , Kwon Soonil , Song Hee-Seok , Lee Young-Shin , Oh Seil 
Published: February 2024

Background
Wearable electrocardiogram (ECG) monitoring devices are used worldwide. However, data on the diagnostic yield of an adhesive single-lead ECG patch (SEP) to detect premature ventricular complex (PVC) and the optimal duration of wearing an SEP for PVC burden assessment are limited.

Objective
We aimed to validate the diagnostic yield of an SEP (mobiCARE MC-100, Seers Technology) for PVC detection and evaluate the PVC burden variation recorded by the SEP over a 3-day monitoring period.

Methods
This is a prospective study of patients with documented PVC on a 12-lead ECG. Patients underwent simultaneous ECG monitoring with the 24-hour Holter monitor and SEP on the first day. On the subsequent second and third days, ECG monitoring was continued using only SEP, and a 3-day extended monitoring was completed. The diagnostic yield of SEP for PVC detection was evaluated by comparison with the results obtained on the first day of Holter monitoring. The PVC burden monitored by SEP for 3 days was used to assess the daily and 6-hour PVC burden variations. The number of patients additionally identified to reach PVC thresholds of 10%, 15%, and 20% during the 3-day extended monitoring by SEP and the clinical factors associated with the higher PVC burden variations were explored.

Results
The recruited data of 134 monitored patients (mean age, 54.6 years; males, 45/134, 33.6%) were analyzed. The median daily PVC burden of these patients was 2.4% (IQR 0.2%-10.9%), as measured by the Holter monitor, and 3.3% (IQR 0.3%-11.7%), as measured in the 3-day monitoring by SEP. The daily PVC burden detected on the first day of SEP was in agreement with that of the Holter monitor: the mean difference was –0.07%, with 95% limits of agreement of –1.44% to 1.30%. A higher PVC burden on the first day was correlated with a higher daily (R2=0.34) and 6-hour burden variation (R2=0.48). Three-day monitoring by SEP identified 29% (12/42), 18% (10/56), and 7% (4/60) more patients reaching 10%, 15%, and 20% of daily PVC burden, respectively. Younger age was additionally associated with the identification of clinically significant PVC burden during the extended monitoring period (P=.02).

Conclusions
We found that the mobiCARE MC-100 SEP accurately detects PVC with comparable diagnostic yield to the 24-hour Holter monitor. Performing 3-day PVC monitoring with SEP, especially among younger patients, may offer a pragmatic alternative for identifying more individuals exceeding the clinically significant PVC burden threshold.

Authors: Villarreal-Zegarra David , García-Serna Jackeline , Segovia-Bacilio Piero , Mayo-Puchoc Nikol , Navarro-Flores Alba , Huarcaya-Victoria Jeff 
Published: February 2024

Background
The COVID-19 pandemic led to a global reduction in health care accessibility for both infected and noninfected patients, posing a particular burden on those with chronic conditions, including mental health issues. Peru experienced significant devastation from the pandemic, resulting in a collapsed health care system and leading to the world’s highest per capita mortality rate as a result of COVID-19. Understanding the trends in health care utilization, particularly in mental health care, is crucial for informing pandemic response efforts and guiding future recovery strategies.

Objective
This study aims to analyze the trends of outpatient medical and psychiatric consultations during the COVID-19 pandemic in a national hospital in Peru.

Methods
This observational study was conducted at a national hospital in Lima, Peru. We analyzed data on user care across all services, including psychiatric services, from May 2019 to December 2022. The data were calculated for users served per month, including the number of users seen monthly in mental health services. Sociodemographic variables such as sex (female or male), age (≥0 years), type of medical appointment (regular or additional), and modality of care (in-person or teleconsultations) were taken into account. An interrupted time series regression model was conducted to assess the number of outpatient medical and psychiatric consultations. Subgroup analyses were performed based on service modality, including overall consultations, telemonitoring/teleconsultations only, or face-to-face only, for all service users and for mental health service users.

Results
A total of 1,515,439 participants were included, with females comprising 275,444/484,994 (56.80%) of the samples. Only 345,605/1,515,439 (22.81%) visits involved telemedicine. The total monthly outpatient visits were significantly reduced compared with the expected projection (P<.001) at the beginning of the pandemic, followed by a later monthly increment of 298.7 users. Face-to-face interventions experienced a significant reduction at the beginning of the pandemic (P<.001), gradually recovering in the following months. By contrast, telemedicine use initially increased but subsequently declined toward the end of the pandemic. A similar trend was observed in mental health units.

Conclusions
During the pandemic years, health care utilization in both general and psychiatric services experienced a significant decrease, particularly at the beginning of the pandemic (March 2020). However, no significant trends were observed in either case throughout the pandemic period. Telemedicine consultations witnessed a significant increase overall during this period, particularly among mental health users.

Perempuan dan Perangkap Kemiskinan di Kelurahan Wonokusumo Kota Surabaya
Authors: Elanda Yelly , Alie Azizah 
Published: February 2024

Kemiskinan dan ketidaksetaraan gender merupakan isu krusial yang ada dalam tujuan pembangunan berkelanjutan (SDGs). Ketidaksetaraan gender menjadi salah satu akar penyebab kemiskinan sehingga keduanya saling terkait. Tujuan penelitian ini yaitu mendeksripsikan kehidupan dan penyebab perempuan yang terjebak dalam perangkap kemiskinan di kota Surabaya. Metode penelitian yang digunakan adalah metodologi feminis dengan jenis kualitatif. Metode ini dipilih agar dapat mengungkap pengetahuan dan pengalaman perempuan yang terjebak dalam perangkap kemiskinan di perkotaan. Data diperoleh dari hasil wawancara dengan 6 informan dengan menggunakan purposive. Selain itu, data juga didapat dari hasil observasi dan studi literature. Teori perangkap kemiskinan Robert Chambers dan teori feminis menjadi pisau analisis dari penelitian ini. Hasil penelitian menunjukkan bahwa terdapat dua golongan perempuan yang terperangkap dalam jerat kemiskinan. Golongan pertama adalah perempuan yang berstatus janda (sebagai kepala keluarga). Golongan kedua merupakan perempuan yang statusnya menikah, sebagai ibu rumah tangga. Tingkat kemiskinan yang dialami oleh kepala rumah tangga perempuan lebih dalam dibandingkan dengan perempuan sebagai ibu rumah tangga, terlebih jika kepala keluarga perempuan merupakan generasi sandwich. Perempuan miskin yang sudah menikah lebih banyak berperan sebagai ibu rumah tangga, jarang sekali ibu rumah tangga yang memiliki usaha atau pekerjaan. Tingkat kemiskinan yang dialami oleh ibu rumah tangga lebih tinggi dibandingkan dengan ibu rumah tangga yang memiliki usaha (pekerjaan). Penyebab terjadinya perangkap kemiskinan pada perempuan di kota Surabaya adalah kemiskinan, keterisolasian, ketidakberdayaan, kelemahan fisik dan kerentanan. Namun faktor dominan yang menyebabkan perempuan terjerat perangkap kemiskinan adalah feminisasi kemiskinan dan relasi gender dalam keluarga yang tidak setara.
