Abstract
The hydrogen recombination lines H30α, H40α, H42α, H50β, and H57γ and the underlying bremsstrahlung continuum emission were detected with ALMA in the bipolar nebula Mz3. The source was not spatially resolved, but the velocity profile of the H30α line shows clear indication of maser amplification, confirming previous reports of laser amplification in the far-infrared H recombination lines observed with Herschel Space Observatory. Comparison between the flux densities of the H50β, H40α, and H42α lines show overcooling, or darkness amplification by stimulated absorption (dasar effect) at the LSR velocity of about −25 km s−1, which constrains the density of the absorbing region to about 103 cm−3. The H30α line, on the other hand, presents maser lines at LSR velocities of −69 and −98 km s−1, which indicates ionized gas with densities close to 107 cm−3. Although the source of emission was not resolved, it was possible to find the central position of the images for each velocity interval, which resulted in a well defined position–velocity distribution.
On the 1/f Spectrum in Slow Solar Wind Turbulence: The Role of Alfvénicity
Authors: Dorseth Mason , Bourouaine Sofiane , Perez Jean C. 
Published: October 2024

Abstract
The slow solar wind has been recently observed to have a number of intervals that are dominated by large-scale Alfvénic fluctuations, especially within 1 au, with similar turbulence characteristics to those found in fast wind streams, including a 1/f range. These results suggest that the slow solar wind exists in at least two flavors: the typical slow wind that generally does not exhibit a 1/f range and an Alfvénic wind that is more similar to fast wind streams. The Alfvénic slow wind is usually differentiated from the typical slow wind (not dominated by Alfvénic fluctuations) by the normalized cross helicity, σ

c
. Values of ∣σ

c
∣ near unity are associated with Alfvénic fluctuations, whereas values near zero are typically thought of as non-Alfvénic. This classification by cross helicity excludes the case of solar wind fluctuations dominated by balanced Alfvénic turbulence, i.e., the turbulence regime where there is equal energy flux of counterpropagating fluctuations propagating along the mean field. We use a large statistical analysis to isolate intervals of slow wind at 1 au in a 20 yr period of Wind data. These intervals are sorted into subsets corresponding to the type of slow wind via the mean values of their magnetic compressibility and cross helicity. Our analysis finds several intervals of low-cross-helicity slow wind dominated by balanced Alfvénic turbulence, which possess similar characteristics found in high-cross-helicity streams. Our results support the conclusion that a 1/f spectrum may be a property associated with streams dominated by Alfvénic turbulence, whether the turbulence is balanced or imbalanced.

Published: October 2024

Xuan Lien Nature Reserve was established in 1999 to protect important habitats and wildlife in the northern part of the Annamites in Vietnam. While Xuan Lien is home to many threatened species, it has experienced a high level of human disturbance over the last decades. To document and provide baseline data on the status and distribution of the terrestrial vertebrate fauna community in the region, we conducted a systematic camera trapping survey in Xuan Lien Nature Reserve in 2023. The data collected during the survey will help design proper conservation measures to better conserve the remaining species.
Our study investigates and updates the species richness of mid- to large-sized terrestrial vertebrates, thus providing essential information for developing conservation strategies in Xuan Lien Nature Reserve, Vietnam. As camera traps were set up in a grid-based design, our survey also generated the first-ever systematic data for terrestrial vertebrate fauna in the area. The study covers approximately 21,000 hectares (about 77% of the area), using 35 camera trap stations; each station consists of two cameras. In total, the final dataset consists of 6,276 trap nights, recording at least 46 species in 39 genera. The results suggest that Xuan Lien is a key stronghold for small carnivores, based on the diversity of such species groups in the Reserve. We failed to detect the previously documented Roosevelt’s muntjac (Muntiacus rooseveltorum Osgood, 1932) and we only documented a single record of the northern red muntjac (Muntiacus vaginalis Boddaert, 1785). Our survey confirms the severity of overhunting and other anthropogenic threats to the mammal fauna, especially ungulates, in the Reserve.
L’expérience spectatrice
Authors: Maignant Aurélien 
Published: October 2024

Comment étudier ce que les spectacles font à leurs publics ? Et comment penser ce que les spectateurs et les spectatrices font aux spectacles ? Ces deux questions animent solidairement cette étude de réception menée au contact d’une centaine de spectateurs et de spectatrices. Mais avant d’interroger le public, elle rencontre les spectacles et les diverses constellations théoriques susceptibles de décrire la capacité d’agir des arts vivants.Le présent essai offre ainsi les conclusions de cet examen préalable à une enquête de terrain – mais qui en constitue aussi le résultat théorique. Fondé sur une grande interdisciplinarité que les mutations des scènes contemporaines rendent toujours plus nécessaire, il propose quatre modèles pour cerner l’éventail des effets politiques qu’un spectacle peut prétendre exercer sur son spectateur ou sa spectatrice. Ces effets sont-ils toujours ceux qui étaient prévus par l’œuvre ? Rien n’est moins sûr…

Published: October 2024

Bokong Nature Reserve (BNR) forms part of the core of the first and newly established Matšeng Biosphere Reserve in Lesotho. However, lack of baseline data makes it difficult to monitor the wetland vegetation in BNR. This study characterised the vegetation of the high-altitude montane palustrine wetlands of this area. Plant species composition was assessed using the Braun-Blanquet approach, and the height and cover of the vegetation were measured. Furthermore, environmental data were collected using standard methods. The data were analysed by determining species richness and calculating Shannon-Wiener diversity and evenness, as well as employing cluster analysis, canonical correspondence analysis and redundancy analysis. The results show that a total of 175 plant species from 102 genera and 40 families were encountered. The dominant plant families were Asteraceae, Poaceae and Cyperaceae. Hierarchical cluster analysis produced 10 plant communities in the range of 1–36 species per 3 m × 3 m plot. Important environmental factors influencing the wetland vegetation were longitude, altitude, latitude, soil sodium, inundation, soil texture, soil magnesium and soil phosphorus. The results indicate that the wetlands are not only in a relatively stable condition, but also support diverse vegetation and store a substantial amount of carbon, thus contributing to biodiversity conservation and climate change mitigation. Because the wetland vegetation determines the functioning of the system, which in turn influences the supply of ecosystem services, our findings form a baseline dataset for monitoring the BNR wetland vegetation, especially in the face of climate change.Conservation implications: The BNR wetlands fall within the catchment of the Lesotho Highlands Water Project dams that are important for water resources in southern Africa. Furthermore, the wetlands are of international conservation value because they form part of the core of a UNESCO-declared man and biosphere reserve and play an important role in supporting biodiversity.
Ischemic Stroke in Young Adults in India: Predictors of Recurrence and Functional Outcome
Authors: Reddy Balaswamy , Kathuveetil Arun , Sreedharan Sapna Erat , Jissa VT , Sylaja PN 
Published: October 2024

Background and Objectives:
Ischemic stroke (IS) in young is increasingly recognized as an important health problem in low- and middle-income countries (LMICs). Limited data is available from LMICs about the predictors of outcome and recurrence of IS in young. The study aims to assess the predictors of short-term and long-term functional outcome and the recurrence of the first-ever IS and transient ischemic attack in young.

Methods:
The clinical, radiological data, functional outcome, and recurrence of 569 IS patients aged 18–50 years were recorded. The etiological classification was done. The functional outcome was assessed using the modified Rankin scale (mRS), with a good outcome being mRS 0–2. Logistic regression was used to analyze the predictors of recurrence and outcome.

Results:
The most common risk factors were hypertension (40.3%) and diabetes mellitus (34.3%). Stroke of undetermined etiology (33.6%) was the most common etiological subtype. Among the cardioembolic subtypes, rheumatic heart disease constituted 47.4%. A good functional outcome at 1 year was seen in 76.3%. While baseline stroke severity predicted both the 3-month and 1-year functional outcome, age ≥40 years and male gender predicted poor outcome at 1 year. The risk of recurrent strokes at 1 year was 2.5%. On multiple logistic regression analysis, diabetes mellitus independently predicted recurrent vascular events at 1 year (odds ratio = 2.43, 95% confidence interval 1.07–5.50).

Conclusions:
We found a good functional outcome with a relatively low recurrence at 1 year among young IS patients. Baseline stroke severity, age, and male gender predicted a poor 1-year functional outcome.

Published: October 2024

Backround:
Information about the chikungunya disease burden by age groups and geographic distribution is necessary to guide appropriate control measures. With this, we conducted a systematic review and meta-analysis to estimate the disease burden of chikungunya fever in India.

Material and Methods:
We conducted this systematic review according to the Cochrane Collaboration guidelines. We retrieved relevant articles from PubMed and a free online search. Two investigators screened titles and abstracts and extracted data from the relevant articles. Our primary outcome is the proportion of laboratory-confirmed Chikungunya fever among clinically suspected patients. We used a random effect model to estimate the pooled proportion of Chikungunya fever.

Result:
A total of 20 articles were included in the quantitative syntheses. The pooled proportion of laboratory-confirmed chikungunya fever from 20 studies estimated using the random effects model is 24% (95%CI: 15-34%). We found the pooled proportion in the southern region was 35% (95%CI: 4-66%), 28% (95%CI: 3-58%) in the western region, 24% (95%CI: 1-48%) in the eastern region, 20% (95%CI: 12-29%) in the northern region, and 4% (95%CI: 1-6%) in North-eastern region.

Conclusion:
This review emphasizes the need to strengthen the surveillance of disease burden using multiple diagnostic tests and the need for an appropriate molecular diagnostic for early detection of the chikungunya virus.
Prevalence of depression among drug-resistant tuberculosis patients in South Asia: A systematic review and meta-analysis
Authors: Thampy Parwathy , Rupani Ashlesh , Chullithala Athira , Pawar Neeraj 
Published: October 2024

Background:
Drug-resistant tuberculosis (DR-TB) significantly increases the risk of depression, yet research on mental health in this population remains limited.

Aim:
This meta-analysis aimed to evaluate the prevalence of depression among multidrug-resistant TB (MDR-TB) patients, emphasizing the necessity for integrated mental health care.

Methods:
A systematic search across PubMed, Cochrane, EBSCOhost, and Google Scholar identified 536 articles, which were screened for eligibility after removing duplicates. Prevalence data were analyzed using R programming, with back-transformation applied to enhance accuracy. The methodological quality of the included studies was assessed with the JBI Critical Appraisal Checklist, and the study protocol is registered in PROSPERO (CRD42023449156).

Results:
Ultimately, twelve studies involving 3,258 participants were included in the analysis. The pooled prevalence of depression among MDR-TB patients was found to be 54% (95% CI: 42%-65%). Although substantial heterogeneity was noted (I² = 72%; P < 0.01), excluding one study (Walker et al.) due to high Cook’s distance revised the prevalence to 55% (95% CI: 43%-68%), with reduced heterogeneity (I² = 68%; P < 0.01). Subgroup analyses indicated minimal variability among studies using the Hamilton Depression Rating Scale (52%, 95% CI: 40%-64%) and substantial variability among those employing the Patient Health Questionnaire (54%, 95% CI: 30%-79%). Funnel plot analysis and Egger’s test revealed no significant publication bias (P = 0.2105).

Conclusion:
This study highlights a high prevalence of depression among MDR-TB patients, underscoring the urgent need for integrated mental health care strategies tailored for this vulnerable population. Further research is essential to refine these strategies effectively.

Abstract

Background:
The advent of implants has been a big milestone in the practice of dentistry, which has largely changed the face of rehabilitative dental practice. The present evaluative study assessed the tissue changes observed with single-unit dental implants placed in conjunction with platelet-rich fibrin (PRF) since there is a relative dearth of studies on this aspect in the literature.

Materials and Methods:
The present prospective study consisted of 12 patients with single-rooted teeth indicated for extraction for various reasons, whereas after immediate insertion of single-unit dental implants, soft and hard tissue changes were assessed at baseline and on follow-up visits of patients at 3, 6, and 9 months, respectively, and the data obtained were subjected to statistical analysis. For carrying out the statistical analysis, a paired t test was used, whereas probability values of 0.05 or less were contemplated as being statistically significant.

Results:
The results in terms of mean modified plaque index and mean modified bleeding index revealed statistically significant variations in follow-up visits of patients (P < 0.05). Similarly, noteworthy differences were observed in terms of the mean papillary index and mean distance between the implant–bone interface (DIB) on either side on follow-up visits of patients using a paired t test (P < 0.05).

Conclusion:
The insertion of single-unit dental implants in conjunction with PRF resulted in a significantly improved height of the interdental papilla. In addition, an appreciable difference was observed in the mean DIB with no major complications after 9 months of implant insertion.
Clinicopathological Characteristics of Multiple Primary Malignancies Involving Female Genital Tract at a Tertiary Cancer Institute of Northeast India
Authors: Kaur Eshwarya Jessy , Barmon Debabrata , Baruah Upasana , Begum Dimpy 
Published: October 2024

ABSTRACT

Background:
The term “Multiple Primary Malignant Neoplasms (MPMNs)” refers to two or more unrelated primary malignant neoplasms that originate from single or different organs and occur in one patient. MPMNs have been divided into synchronous and metachronous based on time duration after first malignancy.

Materials and Methods:
This was a hospital-based retrospective study conducted at a tertiary cancer institute in Northeast India. Clinicopathological factors of patients with multiple primary malignancies with at least one female genital tract malignancy attending the gynecological oncology outpatient department were observed. Those with ambiguous status of primary malignancy and incomplete treatment of first primary malignancy were excluded from the study.

Results:
A total of 57 patients with MPMN, including one case of triple primary malignancy, were included in the study. 59.18% of cases had metachronous, and 40.81% had synchronous malignancies. The median time to the development of second primary malignancy was 60 months. Among the first diagnosed malignancies, cervix was the most common site (26.5%), followed by endometrium (20.4%) and ovary (14.28%), whereas ovarian malignancy was more commonly diagnosed second malignancy (38.77%), followed by endometrium (14.28%) and cervix (10.2%). In an analysis of synchronous malignancies, the most common genital tract involvement was seen with endometrium and ovary, with a predominance of low-grade endometrioid histology in 75% of cases.

Conclusions:
As the cancer survivor population continues to increase in future, these patients must be comprehensively evaluated on follow-up, and a cognizance of prior treatment taken should be kept. In addition, it is vital that the clinicians keep a lookout for high-risk population in which genetic testing may be beneficial.
Geospatial analysis of land use changes and wetland dynamics in Kaduna Metropolis, Kaduna, Nigeria
Authors: Abubakar Muhammad Lawal , Abdussalam Auwal Farouk 
Published: October 2024

Wetlands are among the world's most valuable ecosystems, and changes in land use have an impact on their distribution, health, quality, functions, and provision of services. This study assessed how land use change and socioeconomic activities drove wetland conversion in Kaduna Metropolis from 1986--2023. Landsat images (189/053) and SRTM DEMs were obtained from the USGS. The index-based classification was used to identify and map the wetlands in the study area and was also used for land use/land cover analysis classification via eCognition 9.0. A land change modeler on Idrisi Terrset was used to carry out land use/land cover change detection and transition analysis. The analysis of the results revealed an overall accuracy of 92% (0.93 Kappa) for the 1986 classification and 90% (0.88 Kappa) for the 2023 classification. The LULC analysis revealed that built-up areas and vegetation increased by 194.9 km2 and 60.9 km2, respectively, whereas bare land decreased by 136.5 km2 . With respect to wetland dynamics, marshlands lost a total of 15 km2 , riparian vegetation lost 28.6 km2, and water bodies declined by 2.6 km2 . The study concluded that settlement expansion and agricultural activities are the primary drivers of wetland changes in Kaduna metropolis. The study therefore recommends the creation of buffer zones around the wetlands to prevent further encroachment.
An assessment of characteristics of rainfall and temperature variability in Dadinkowa Yamaltu Deba LGA OF Gombe State, Nigeria
Authors: Bello Muhammed Yerima , Bashir Bello Muhammed , Abubakar Hauwa 
Published: October 2024

The study aims to assess the rainfall and temperature pattern to suggest some resilience mechanisms, the farmers' perception of rainfall and temperature variability, and adaptation strategies. Rainfall and temperature data (1989-2018) from the Upper Benue River Basin Development Authority Hydrological Department and a structured research questionnaire were used for this study. Statistical tools commonly used to describe climates such as mean, range, standard deviation, and coefficient of variation were employed. Standardized precipitation Index for the study revealed the first decade (1989-1998) had the highest number of dry years; five (5) moderately dry years, one (1) severe dry year, and one (1) extremely dry year. This was followed by the third decade (2009- 2018), with four (4) moderately dry years and one (1) severe dry year. And lastly the Second decade (1990-2018); with only three (3) moderately dry years. Whereas the third decade (2009-2018) had the highest number of wet years with four (4) slightly wet years, two (2) moderately wet years, and one (1) considerably wet year. The second decade (2009-2018) was relatively wet with three (3) slightly wet years, one moderately wet year, one (1) considerably wet, and one extremely wet year while the first decade (1989-1998) had only five 5 slightly wet years. The last two decades (1999-2008 and 2009-2018) were found to be wet while the first decade was dry. The study showed a temporal distribution of annual mean temperature in Dadin-kowa. The result revealed that the region experienced a rising and falling pattern from 1989 up to 2010. The region then started experiencing a rise from 2010 down to the end of the study period. Late onset of rains and increase in temperature have been experienced by the farmers and understood as evidence of variation in climate. The findings of both empirical data and of the questionnaire agreed that there is evidence of climate variability that can be explained in terms of rainfall and temperature variability in the area. The coping strategies employed include the use of locally made fertilizer, irrigation, and change of planting date, mixed cropping, and use of planting period techniques. Thus, awareness raising on climate variability, weather forecasting, and expanding existing irrigation infrastructure among others were recommended to help ameliorate the effects of climate change on the farmers' cropping practices.
