A change in the relation between the Subtropical Indian Ocean Dipole and the South Atlantic Ocean Dipole indices in the past four decades
Authors: Yu Lejiang , Zhong Shiyuan , Vihma Timo , Sui Cuijuan , Sun Bo
Published: January 2023

Abstract. We utilized the global atmospheric reanalysis ERA5 and reconstructed sea
surface temperature (SST) data from 1979 through 2020 to examine the
stability of the relationship between the SST oscillations in the southern
Indian Ocean and the Atlantic Ocean, as described by the Subtropical Indian Ocean Dipole (SIOD) and South Atlantic Ocean Dipole (SAOD) indices, respectively. We note a significant positive correlation between the two indices prior to the year 2000 but practically no correlation afterwards. We show that in the two decades prior to 2000, a positive phase of the SAOD is associated with more convective activities over the subtropical southern Atlantic Ocean and eastern Brazil, which trigger a stronger upper-atmosphere wavetrain. This produces stronger southern subtropical highs and surface anti-cyclonic circulations and therefore a stronger correlation between the two indices. The situation is reversed after 2000. Our results are potentially applicable to predictions of precipitation in southern Africa and South America.
Understanding the potential of Sentinel-2 for monitoring methane point emissions

Published: January 2023

Abstract. The use of satellite instruments to detect and quantify methane emissions from fossil fuel production activities is highly beneficial to support climate change mitigation.
Different hyperspectral and multispectral satellite sensors have recently shown potential to detect and quantify point-source emissions from space.
The Sentinel-2 (S2) mission, despite its limited spectral design, supports the detection of large emissions with global coverage and high revisit frequency thanks to coarse spectral coverage of methane absorption lines in the shortwave infrared. Validation of S2 methane retrieval algorithms is instrumental in accelerating the development of a systematic and global monitoring system for methane point sources. Here, we develop a benchmarking framework for such validation. We first develop a methodology to generate simulated S2 datasets including methane point-source plumes.
These benchmark datasets have been created for scenes in three oil and gas basins (Hassi Messaoud, Algeria; Korpeje, Turkmenistan; Permian Basin, USA) under different scene heterogeneity conditions and for simulated methane plumes with different spatial distributions. We use the simulated methane plumes to validate the retrieval for different flux rate levels and define a minimum detection threshold for each case study.
The results suggest that for homogeneous and temporally invariant surfaces, the detection limit of the proposed S2 methane retrieval ranges from 1000 to 2000 kg h−1, whereas for areas with large surface heterogeneity and temporal variations, the retrieval can only detect plumes in excess of 500 kg h−1. The different sources of uncertainty in the flux rate estimates have also been examined. Dominant quantification errors are either wind-related or plume mask-related, depending on the surface type.
Uncertainty in wind speed, both in the 10 m wind (U10) and in mapping U10 to the effective wind (Ueff) driving plume transport, is the dominant source of error for quantifying individual plumes in homogeneous scenes.
For heterogeneous and temporally variant scenes, the surface structure underlying the methane plume affects the plume masking and can become a dominant source of uncertainty.
Calibrating Radar Wind Profiler Reflectivity Factor using Surface Disdrometer Observations

Published: January 2023

Abstract. This study uses surface disdrometer reflectivity factor estimates to calibrate the vertical and off-vertical pointing radar beams produced by an Ultra High Frequency (UHF) band radar wind profiler (RWP) deployed at the US Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) program Southern Great Plains (SGP) Central Facility in northern Oklahoma from April 2011 through July 2019. The methodology consists of five steps. First, the recorded Doppler velocity power spectra are adjusted to account for Nyquist velocity aliasing and coherent integration filtering effects. Second, the spectrum moments are calculated. The third step increases the signal-to-noise ratio (SNR) due to signal power leakage during the Fast Fourier Transform (FFT) calculation, which can exceed 20 dB during convective rain events. The fourth step determines the RWP calibration constant for one radar beam (called the “reference” beam) by comparing uncalibrated RWP reflectivity factors at 500 m above the ground to 1-min resolution surface disdrometer reflectivity factors. The last step uses the calibrated reference beam reflectivity factor to calibrate the other radar beams during precipitation. There are two key findings. The RWP sensitivity decreased approximately 3-to-4 dB/year as the hardware aged. This drift was slow enough that the reference calibration constant can be estimated over 3-month intervals using episodic rain events. Calibrated moments are available on the DOE ARM data archive and Python processing code is available on a public GitHub repository.
The Weddell Gyre heat budget associated with the Warm Deep Water circulation derived from Argo Floats

Published: January 2023

Abstract. The Weddell Gyre plays an important role in the global climate system by supplying heat to underneath the ice shelves, and to the formation of deep and bottom water masses, which have been subject to widespread warming over past decades. In this study, we investigate the redistribution of heat throughout the Weddell Gyre by diagnosing the terms of the heat conservation equation for a 1000 m thick layer of water encompassing the core of Warm Deep Water. The spatial distribution of the different advective and diffusive terms in terms of heat tendencies are estimated using gridded climatologies of temperature and velocity, obtained from Argo floats in the Weddell Gyre from 2002 to 2016. While the results are somewhat noisy on the grid scale, the heat budget (i.e., the sum of all terms) nearly closes when integrated over the southern limb and the interior circulation cell of the Weddell Gyre. There is an overall balance between the mean horizontal advection and horizontal turbulent diffusion of heat, whereas the vertical terms contribute comparatively little to the heat budget. Heat convergence due to mean horizontal advection balances with divergence due to horizontal turbulent diffusion in the southern limb of the Weddell Gyre. In contrast, heat divergence due to mean horizontal advection nearly balances with convergence due to horizontal turbulent diffusion in the interior circulation cell of the Weddell Gyre. Heat is advected into the Weddell Gyre along the southern limb, some of which is turbulently diffused northwards into the interior circulation cell, while some is turbulently diffused southwards towards the shelf seas. This suggests that horizontal turbulent diffusion plays a role in transporting heat both towards the gyre interior where upwelling occurs, as well as towards the ice shelves. Horizontal turbulent diffusion is also a mechanism by which heat can be transported into the Weddell Gyre across the open northern boundary.

Authors: Cruz Júnior Antenor Oliveira , da Ponte-Neto Cosme Ferreira , Wiermann André
Published: January 2023

Abstract. Geoelectrical resistivity is an excellent method to investigate the structural composition of shallow subsurfaces. However, existing commercial equipment is typically expensive and often requires proprietary accessories and software to provide full system functionality. The objective of this study was to develop a multichannel, modular, automated, and programmable geo-resistivity meter capable of user customization and programming. To this end, a conceptual prototype was built based on free software and open hardware technologies as a low-cost alternative to commercial equipment while maintaining the accuracy and quality of the data at the same level. The prototype was based on electrode multiplexing to make the switching process more efficient by reducing cabling complexity, whereas synchronous demodulation for signal detection was employed, providing strong rejection of spurious electrical noise, typical of urban areas where such equipment is frequently used. The results demonstrate the feasibility of this project and an important academic contribution to open-source instrumental research.
HIDRA2: deep-learning ensemble sea level and storm tide forecasting in the presence of seiches – the case of the northern Adriatic
Authors: Rus Marko , Fettich Anja , Kristan Matej , Ličer Matjaž
Published: January 2023

Abstract. We propose a new deep-learning architecture HIDRA2 for sea level and storm tide modeling, which is extremely fast to train and apply and outperforms both our previous network design HIDRA1 and two state-of-the-art numerical ocean models (a NEMO engine with sea level data assimilation and a SCHISM ocean modeling system), over all sea level bins and all forecast lead times. The architecture of HIDRA2 employs novel atmospheric, tidal and sea surface height (SSH) feature encoders as well as a novel feature fusion and SSH regression block. HIDRA2 was trained on surface wind and pressure fields from a single member of the European Centre for Medium-Range Weather Forecasts (ECMWF) atmospheric ensemble and on Koper tide gauge observations. An extensive ablation study was performed to estimate the individual importance of input encoders and data streams. Compared to HIDRA1, the overall mean absolute forecast error is reduced by 13 %, while in storm events it is lower by an even larger margin of 25 %. Consistent superior performance over HIDRA1 as well as over general circulation models is observed in both tails of the sea level distribution: low tail forecasting is relevant for marine traffic scheduling to ports of the northern Adriatic, while high tail accuracy helps coastal flood response. Power spectrum analysis indicates that HIDRA2 most accurately represents the energy density peak centered on the ground state sea surface eigenmode (seiche) and comes a close second to SCHISM in the energy band of the first excited eigenmode. To assign model errors to specific frequency bands covering diurnal and semi-diurnal tides and the two lowest basin seiches, spectral decomposition of sea levels during several historic storms is performed. HIDRA2 accurately predicts amplitudes and temporal phases of the Adriatic basin seiches, which is an important forecasting benefit due to the high sensitivity of the Adriatic storm tide level to the temporal lag between peak tide and peak seiche.
SMPD: a soil moisture-based precipitation downscaling method for high-resolution daily satellite precipitation estimation

Published: January 2023

Abstract. As a key component in the water and energy cycle, estimates of precipitation with high resolution and accuracy is of great significance for hydrological, meteorological, and ecological studies. However, current satellite-based precipitation products have a coarse spatial resolution (from 10 to 50 km) not meeting the needs of several applications (e.g., flash floods and landslides). The implementation of spatial downscaling methods can be a suitable approach to overcome this shortcoming. In this study, we developed a soil moisture-based precipitation downscaling (SMPD) method for spatially downscaling the integrated multisatellite retrievals for global precipitation measurement (IMERG) V06B daily precipitation product over a complex topographic and climatic area in southwestern Europe (Iberian Peninsula) in the period 2016–2018. By exploiting the soil-water balance equation, high-resolution surface soil moisture (SSM) and normalized difference vegetation index (NDVI) products were used as auxiliary variables. The spatial resolution of the IMERG daily precipitation product was downscaled from 10 to 1 km. An evaluation using 1027 rain gauge stations highlighted the good performance of the downscaled 1 km IMERG product compared to the original 10 km product, with a correlation coefficient of 0.61, root mean square error (RMSE) of 4.83 mm and a relative bias of 5 %. Meanwhile, the 1 km downscaled results can also capture the typical temporal and spatial variation behaviors of
precipitation in the study area during dry and wet seasons. Overall, the
SMPD method greatly improves the spatial details of the original 10 km IMERG product also with a slight enhancement of accuracy. It shows good potential to be applied for the development of high-quality and high-resolution precipitation products in any region of interest.

Published: January 2023

Veterinarians are the primary sourceof knowledge for farmers on how to use antibiotics responsibly in farm animals and how to decrease the risk of antibiotic resistance.Antimicrobial use and resistance is a multidimensional construct that lacks a specific measurement scale. This paper looks into the development of a scale to assess veterinarian perception about antimicrobial use and resistance. Following a thorough literature review, focus group interviews were conducted with selected key informant veterinarians to identify statements.An initial list of 80 statements reflecting positive and negative perception towards antimicrobial use and resistance was prepared. After editing, a final list of 70 statements were arrivedat. Descriptives of antimicrobial use and resistance, consensus regarding antimicrobial use and resistance indicators were arrived at through relevancy rating by a panel of 40 judges in the field of veterinary science based on which 35 statements were selected for item analysis. These 35 statements were subjected to item analysis among 60 veterinarians selected from a non-sample area. Out of the 60 veterinarians to whom the items were administered for item analysis, 15 veterinarians each with the lowest and highest scores were used as the two criterion groups to evaluate individual items. Individual items were selected based on‘t’ value whereinitems that had a t-value of more than 1.75 were selected and incorporated into the final schedule. Based on the calculated‘t’ values, 14 items were finally selected and includedin the final scale. Reliabilityof the scale was tested using Cronbach’s alpha coefficient of reliability test for which a Cronbachalpha of 0.852 was obtained indicating the internal consistancy of the scale.

Published: January 2023

Campylobacteriosis caused by Campylobacter spp. is the prime cause of bacterial gastroenteritis worldwide. Chicken and other poultry birds act as the major reservoir for Campylobacter and thereby play a crucial role in the transmission of this zoonotic disease to humans. The current investigation was undertaken to study the occurrence of Campylobacter in organised layer farms and their associated environmental samples. A total of 260 samples comprising of cloacal swabs, feed, litter, soil, water and handwash of personnel were collected from two organised layer farms of Thrissur and Ernakulam districts. Isolation and identification of the organism by conventional culture technique followed by molecular confirmation of Campylobacter isolates using multiplex polymerase chain reaction (mPCR) revealed an overall occurrence of 17.31 per cent in layer farms. Majority of the isolates obtained in the study were C. jejuni (75.6 per cent) followed by C. coli (24.4 per cent). In the current scenario, where the consumer demand for chicken meat and eggs is continuously increasing, the occurrence of Campylobacter in layer farms needs to be addressed seriously. Appropriate interventions and control measures at farm level and also across the poultry production chain is necessary to minimise the impact of the disease on human health and economy.

Published: January 2023

Desmoplastic reactions or desmoplasia, characterised by proliferation of fibrotic connective tissue around tumour cells, have been described as a prognostic indicator of malignancy in human breast cancers. Desmoplasia ultimately results in deposition of collagen that shows significant differences in its density and orientation at different stages of tumourigenesis. The different collagen patterns associated with tumours are referred to as tumour associated collagen signatures (TACS) and are identified as hallmarks in human tumourigenesis. The present study was aimed to demonstrate the presence of TACS in canine mammary tumours (CMTs). The desmoplastic reactions and collagen deposition occurring in association with CMTs were analysed using routine histopathological, special staining and scanning electron microscopy techniques. Thirty excisional biopsy samples collected from malignant CMTs were utilised for studying the progression of desmoplastic reactions occurring in the tumour associated stroma.

Published: January 2023

Pigeons are reared as a symbol of peace, love, gentleness and spirit messengers and now-a-days also for meat, as ornamental pet bird or as an experimental animal. There are about 400 varieties of fancy pigeons and little is known about the diseases and management of these birds. Heavy mortality has been observed in the pigeons that shows neurological manifestations. The present study is aimed at diagnosis of infectious diseases causing neurological signs in pigeons. The study was conducted in the different pigeon lofts of four districts in Kerala and a total of 44 pigeons comprising 21 fancy breeds were included. These birds were screened for major infectious etiologies causing neurological signs like paramyxoviral infection, salmonellosis and Haemoproteus infection. The birds were also screened for presence of ectoparasites by visual examination. The study showed 63.63 per cent positive for paramyxoviral infection using antigen NDV kits. The occurrence of Haemoproteus infection was 54.7 per cent in Giemsa-stained blood smears and 63.63 per cent in PCR amplifying cyt b gene. Pseudolynchia canariensis could be detected in pigeons. Isolation and identification of Salmonella from faecal samples were done by culture and biochemical tests and found to be 22.2 per cent. Combined infections of paramyxovirus infection with Haemoproteus, paramyxovirus infection with Salmonella, Haemoproteus with Salmonella and infection of all the three etiologies were the interesting finding of the study. The present study is one of its kind in Kerala and also in India. The study warrants the prevention and control of these infectious diseases which has great zoonotic potential.

Authors: Unni S. Kumar , Umesh C.G. , Thomas Magna , Sindhu O.K. , Ajithkumar S.
Published: January 2023

Sub-acute ruminal acidosis (SARA) in dairy cattle is a disorder of ruminal fermentation caused by the ingestion of large amounts of concentrates with inadequate amounts of fibre. The condition is characterized by sustained and marked decrease in rumen liquor pH ≤5.5 for at least three hours of each day. Rumen buffers and direct fed microbials (DFM) are dietary supplements that had been used in the management of SARA. Rumen liquor samples of dairy cows from the organized farms and households of Wayanad district which were at the risk of SARA were collected by rumenocentesis for rumen pH estimation. Blood samples were collected from cows positive for SARA and subjected to haemato-biochemical evaluations. Three different therapeutic protocols involving oral administration of sodium bicarbonate, Lithothamnium calcareum extracts as rumen buffers and a mixture Saccharomyces cerevisiae and Aspergillus oryzae as direct fed microbial were compared in SARA positive cows for 14 days and the efficacy of the treatment was evaluated by the improvement in rumen liquor pH after the treatment period. Rumen buffer like sodium bicarbonate was found to be more efficient than Lithothamnium calcareum and DFMs like Saccharomyces cerevisiae and Aspergillus oryzae mixture in improving the rumen pH values in cattle positive for SARA.

Published: January 2023

The article is intended to uncover the connection between liquidity and profitability in such a way that each bank must preserve this link while undertaking its day-to-day operational activities. The investigation employed listed banks on the Ghana Stock Exchange from the dated 2008 - 2018. Two estimators namely the Ordinary Least Square (OLS) and the Generalized Method of Moments (GMM) were utilized. To add to existing literature, the liquidity parameters employed in this study exhibited a favorable and significant link with the dependent indicators except for quick ratio which exhibited an immaterial affiliation. In addition, a robustness assessment was employed adopting the three-stage least-squares and the findings were parallel to that of the other estimators employed. The above insights are vital as regulators concoct changing standards offering banks with an optimal degree of liquidity. Although it is widely accepted that, prior to the latest financial crisis, banks undervalued liquidity, and the trade - offs between sensitivity to liquidity fluctuations and the risk of maintaining lower-yielding liquid assets must also be weighed, as the latter will influence the capacity of banks augment earnings and expand credit.

On the origin of the “Ikantalaka” landslide — the Balchik coast
Authors: Evstatiev Dimcho , Evlogiev Yordan
Published: January 2023

The Ikantalaka landslide emerged in the beginning of the Karangatian transgression (Riss-Würm) under the effect of strong earthquakes. The greater part of it represented a submerged landslide, the evidence for this being the structure of the slided masses. The main factors for this were the local hydrogeological circumstances (a big gully mouthed the landslide from the plateau) and the local tectonic conditions (probably a fault existed in perpendicular direction to the coastline). The landslide body is built mainly of the aragonite clays of the Topola Formation (Sarmatian: Upper Bessarabian — Lower Hersonian, which are characterized by high sensitivity and susceptibility to softening. The zone, along which the sliding occurred, comprises the contacte between this Formation and the Euxinograd Formation embedded underneath (Sarmatian: Upper Karaganian — Middle Bessarabian). The latter is represented by diatomic clays, intercalated by thin clayey sand layers. Its surface is inclined at 3—4° towards the sea.

Indonesian to English Noun Phrase Meaning Equivalence on Food Lists from Several Restaurants in Ubud Gianyar Bali
Authors: Susianti Woro , Ni Wayan Pastini
Published: January 2023

The declining numbers of arrival of foreign tourists to the island of Bali has led to some intense competitions in obtaining customers in restaurants, located in the area of Ubud Gianyar. To anticipate such things, foreign language skills, especially English is very important, especially for waiters in the restaurants, who are required to be able to explain the food / menu in English, so the customers will feel satisfied because they understand the food ordered. This study aims to describe the equivalence of Indonesian phrases into English about food on the food lists in several restaurants in Ubud. The data were analyzed using qualitative linguistic theory, which relies on a phenomenological philosophical approach.

The results showed that all restaurants used Modificative Noun phrases, and 80% of them also used Appositive noun phrases.  While Coordinative Noun phrases are only used by 10% of restaurants. Furthermore, it is suggested to the restaurant managers to use simpler noun phrases, so that it becomes easier for guests to understand the meaning of Indonesian phrases that are stated in English noun phrases. In addition, it will also make it easier for waiters to explain the food menu available at the restaurant.

Screening of lactic acid bacteria (LAB) was carried out from samples of natural cow's milk of fresh milk from the main breeds used for industrial milk production. Bacteria were isolated purposefully on selective liquid-phase and agar media. As a result of research, 24 strains of bacteria with fermenting ability were obtained. A preliminary assessment of the safety and expediency of using isolated bacterial strains as probiotics was carried out: Gram staining, the study of catalase and hemolytic activity, as well as the degree of adhesiveness and growth rates in milk. Six LAB strains showed the best results in terms of a combination of indicators, while growth in a nutrient milk medium during the production of functional drinks reached high values and amounted to 1.5x10 CFU/cm. These microorganisms were identified using the MALDI-TOF MS method and belong to the genera Streptococcus thermophilus, Enterococcus faecium, Lactococcus lactis, and Lactobacillus plantarum, promising from the point of view of their use as probiotics.
Uso de albúmina a largo plazo en el paciente cirrótico. Revisión sistemática
Authors: González-Domínguez Esteban Horacio , Marín-Tirado Henry Ariel , Torres-Cueva Gabriela de los Ángeles
Published: January 2023

Introducción. La cirrosis constituye la etapa final de la enfermedad hepática crónica, con una alta mortalidad, y puede deberse a diferentes etiologías. La albúmina tiene tres indicaciones bien establecidas: la prevención de la disfunción circulatoria inducida por paracentesis, la peritonitis bacteriana espontánea y el síndrome hepatorrenal, sin embargo, su uso a largo plazo es controvertido. El objetivo de esta revisión fue identificar si el uso prolongado de la albúmina tiene efectos beneficiosos en el tratamiento de pacientes cirróticos. Metodología. Se realizaron búsquedas en la base de datos de PubMed, empleando los siguientes términos: ("Liver Cirrhosis"[Mesh]) AND ("Serum Albumin"[Mesh] OR "Serum Albumin, Human"[Mesh]). Se excluyeron los artículos que no cumplieron con la temática y aquellos que tenían más de 5 años de antigüedad, a excepción de aquellos relevantes para la revisión. Resultados. Se ha demostrado en varios estudios realizados en los últimos 4 años, que la administración prolongada de albúmina reduce la mortalidad en el paciente cirrótico. Además, resulta en una disminución en ingresos hospitalarios por complicaciones de la cirrosis, disminución de la necesidad de paracentesis y menor uso de albúmina para otras indicaciones ya establecidas, lo que contrarresta los costos derivados de la terapia. Conclusión. Se concluye con base en la evidencia presentada, que el uso de albúmina a largo plazo podría resultar beneficioso en pacientes con cirrosis hepática descompensada.

Introducción. El objetivo de esta investigación fue comparar el perfil bioquímico y clínico de los pacientes con hiperferritinemia secundaria a hemocromatosis hereditaria (HH), frente a aquellos con hiperferritinemia por causas sospechosas de sobrecarga de hierro (Fe) diferentes a la HH. Metodología. Se estudiaron 92 pacientes (61 hombres y 31 mujeres), remitidos tras la detección de valores de ferritina >300 μg/L en hombres y >200 μg/L en mujeres. En todos se analizaron datos demográficos generales, comorbilidades, motivo de remisión para estudios de hiperferritinemia, manifestaciones clínicas, antecedente familiar de HH y tratamiento recibido. Los resultados de las pruebas de laboratorio, imagenología, hallazgos histopatológicos y estudios genéticos, se describieron según la disponibilidad. Resultados. El 96,74 % de los pacientes fueron evaluados en consulta externa, 86,96 % procedían de Medellín o de otros municipios de Antioquia, Colombia. La edad promedio de los participantes fue de 52 años, la principal razón para ser derivados para estudios fue la elevación de los marcadores de Fe sérico, la causa más frecuente de hiperferritinemia fueron los diagnósticos diferentes a la HH (64,13 %) y entre quienes no tenían HH, la etiología metabólica fue la más común (59,32 %). Los pacientes con HH tuvieron niveles más elevados de ferritina y Fe sérico, mientras que en el grupo sin HH se presentaron mayores elevaciones en la saturación de transferrina, transferrina y transaminasas. En pacientes con sobrecarga de Fe, la mutación más frecuentemente encontrada fue la homocigota H63D (36,67 %). Finalmente, 93,94 % de los pacientes con HH recibieron tratamiento con flebotomías, mientras que los cambios en el estilo de vida fueron indicados en el 55,93 % de los pacientes sin HH. Conclusiones. La hiperferritinemia es unapresentación clínica frecuente y es importante hacer un abordaje sistemático para identificar sus causas. Aunque la HH es una causa importante de elevación persistente de ferritina, en el enfoque de los pacientes con esta condición, se deben descartar etiologías más frecuentes como la hiperferritinemia de etiología metabólica.

U sợi thần kinh type 1 (neurofibromatosis type 1 - NF1) là bệnh di truyền trội trên nhiễm sắc thể (NST) thường do đột biến gen neurofibromin (NF1) gây ra. Bệnh có biểu hiện đặc trưng là các khối u ở mô thần kinh, thường gặp trên da. Nghiên cứu với mục tiêu mô tả đặc điểm lâm sàng, gia hệ, kết quả xét nghiệm gen NF1 và tư vấn di truyền của ba ca bệnh NF1. Nghiên cứu qua khai thác phả hệ, tiền sử, bệnh sử, thăm khám lâm sàng sơ bộ. Đột biến gen NF1 được phát hiện bằng xét nghiệm giải trình tự hệ thế hệ mới và/hoặc xét nghiệm giải trình tự trực tiếp Sanger. Các đặc điểm lâm sàng rất thay đổi giữa các bệnh nhân mắc NF1, bệnh nhân có thể có tiền sử gia đình có người bị bệnh hoặc không. Các ca bệnh có đột biến gen khác nhau trên gen NF1 và đều dẫn tới ngừng dịch mã. Tư vấn di truyền nhằm cung cấp các thông tin liên quan đến tiến triển và biến chứng có thể gặp phải của bệnh, các biện pháp điều trị bệnh hiện tại, quy luật di truyền, nguồn gốc đột biến và khả năng di truyền gen bệnh cho con cái. Xác định đột biến gây bệnh có ý nghĩa quan trọng cho chẩn đoán sớm và chẩn đoán trước sinh/chẩn đoán trước chuyển phôi.

Nghiên cứu nhằm mô tả đặc điểm lâm sàng, cận lâm sàng, tỷ lệ tử vong sớm và một số yếu tố liên quan đến tử vong trong 30 ngày ở bệnh nhân tắc động mạch phổi cấp kèm ung thư. Đây là một nghiên cứu mô tả hồi cứu. Chẩn đoán xác định tắc động mạch phổi cấp khi có bằng chứng huyết khối trong động mạch phổi trên cắt lớp vi tính có thuốc cản quang. Nghiên cứu có 39 bệnh nhân được đưa vào mô tả. Trong đó, 24/39 bệnh nhân (61,5%) phát hiện ung thư trước khi được chẩn đoán tắc động mạch phổi cấp, 15/39 bệnh nhân (38,5%) nhập viện với biểu hiện của tắc động mạch phổi cấp được tìm thấy ung thư trong cùng đợt điều trị. Tỉ lệ các loại ung thư gặp trong nghiên cứu là ung thư phổi 17/39 (43,6%), có 29/39 (74,3%) bệnh nhân đã có di căn xa. Tỉ lệ tử vong ở bệnh nhân tắc động mạch phổi cấp kèm ung thư sau 7 ngày điều trị là 4/39 (10,3%), và sau 30 ngày là 12/39 (30,8%). Điểm sPESI cao hơn ở nhóm bệnh nhân tử vong trong 30 ngày.

Một phần ba dân số thế giới là phụ nữ. Chất lượng sống của phụ nữ quan trọng để đảm bảo gia đình hạnh phúc và khỏe mạnh. Mục tiêu của nghiên cứu là mô tả chất lượng sống bằng WHOQOL-BREF và một số yếu tố liên quan ở phụ nữ kết hôn tại tỉnh Long An, Việt Nam. Nghiên cứu cắt ngang thực hiện vào tháng 3/2017 đến tháng 8/2018 tại 14 huyện và 1 thành phố thuộc tỉnh Long An. Phụ nữ đã kết hôn đến khám phụ khoa tại các trạm y tế được chọn vào nghiên cứu. Đặc điểm của phụ nữ và chất lượng sống được thu thập qua phỏng vấn mặt đối mặt. Tuổi trung bình của 454 phụ nữ được chọn vào nghiên cứu là 30,5 ± 6,8. Thu nhập trung bình của gia đình là 7,7 ± 5,4 triệu. Hầu hết phụ nữ có cân nặng bình thường (84,4%), sống ở nông thôn (74,2%), không có bệnh kèm theo (94,5%), sống với chồng (94,3%) và chưa từng sử dụng các biện pháp tránh thai trước đây (64,1%). Điểm chất lượng sống trung bình theo thang điểm 100 ở lĩnh vực thể chất 51,5 ± 11,4, tinh thần 54,0 ± 10,3, quan hệ xã hội 60 ± 12,9 và môi trường 57,2 ± 10,9. Học vấn và không sống với chồng (chồng thường không có ở nhà) là hai yếu tố liên quan chặt chẽ đến chất lượng sống của phụ nữ ở tất cả bốn lĩnh vực thể chất, tinh thần, xã hội và môi trường sống. Các chương trình chăm sóc sức khỏe sinh sản nên lưu ý ưu tiên nhóm phụ nữ có học vấn thấp và không sống với chồng để đảm bảo phụ nữ được chăm sóc tốt nhất.

Thoái hóa khớp gối và hội chứng chuyển hóa là gánh nặng y tế trên toàn thế giới do vấn đề béo phì và già hóa dân số tăng nhanh. Mục tiêu nghiên cứu nhằm đánh giá mối liên quan giữa hội chứng chuyển hóa và các thành phần của nó với độ nặng thoái hóa khớp gối theo giai đoạn X-quang ở người trên 40 tuổi. Nghiên cứu được thực hiện trên 430 người trên 40 tuổi đăng ký tham gia tại Phòng nghiên cứu Cơ Xương, Trường Đại học Tôn Đức Thắng từ 01/2022 đến 06/2022. Kết quả cho thấy ở người thoái hóa khớp gối trên 40 tuổi, hội chứng chuyển hóa làm tăng khả năng tiến triển đến giai đoạn X-quang muộn gấp 3,26 lần (KTC 95%: 2,11 - 5,04, p < 0,001), sau khi hiệu chỉnh cho các yếu tố gây nhiễu, mối liên quan vẫn duy trì với OR hiệu chỉnh = 1,78 (KTC 95%: 1,09 - 2,90, p = 0,020). Ngoài ra, tăng vòng eo, tăng huyết áp và tăng đường huyết cũng làm tăng khả năng tiến triển đến giai đoạn X-quang muộn với OR lần lượt là 2,89; 2,59 và 2,65.

Việc gia tăng tỷ lệ Klebsiella pneumoniae kháng carbapenem đang trở thành mối lo của toàn thế giới.1 Các chủng Klebsiella pneumoniae kháng carbapenem do sinh men carbapenemase hoặc kết hợp với sinh ESBL, AmpC. Trong nghiên cứu này, kiểu gen mã hóa carbapenemase được phát hiện bằng kỹ thuật PCR như blaKPC, blaNDM, blaOXA48, blaVIM, blaIMP trong số 187 chủng Klebsiella pneumoniae sinh carbapenemase. Kiểu gen mã hóa carbapenemase phổ biến nhất là blaKPC (58,3%), blaNDM (21,4%) và blaOXA-48-like (18,7%). Nghiên cứu không phát hiện chủng nào mang gen blaVIM hay blaIMP. Có 53 trong số 187 chủng mang gen mã hóa carbapenemase phối hợp như blaKPC+blaNDM, blaKPC+blaOXA48-like, blaNDM+blaOXA-48-like và blaKPC+blaNDM+blaOXA-48-like. Các chủng này đề kháng cao với hầu hết các kháng sinh sử.
