Abstract
The two-planet transiting system LHS 1140 has been extensively observed since its discovery in 2017, notably with Spitzer, HST, TESS, and ESPRESSO, placing strong constraints on the parameters of the M4.5 host star and its small temperate exoplanets, LHS 1140 b and c. Here, we reanalyze the ESPRESSO observations of LHS 1140 with the novel line-by-line framework designed to fully exploit the radial velocity content of a stellar spectrum while being resilient to outlier measurements. The improved radial velocities, combined with updated stellar parameters, consolidate our knowledge of the mass of LHS 1140 b (5.60 ± 0.19 M
⊕) and LHS 1140 c (1.91 ± 0.06 M
⊕) with an unprecedented precision of 3%. Transits from Spitzer, HST, and TESS are jointly analyzed for the first time, allowing us to refine the planetary radii of b (1.730 ± 0.025 R
⊕) and c (1.272 ± 0.026 R
⊕). Stellar abundance measurements of refractory elements (Fe, Mg, and Si) obtained with NIRPS are used to constrain the internal structure of LHS 1140 b. This planet is unlikely to be a rocky super-Earth, as previously reported, but rather a mini-Neptune with a ∼0.1% H/He envelope by mass or a water world with a water-mass fraction between 9% and 19%, depending on the atmospheric composition and relative abundance of Fe and Mg. While the mini-Neptune case would not be habitable, a water-abundant LHS 1140 b potentially has habitable surface conditions according to 3D global climate models, suggesting liquid water at the substellar point for atmospheres with relatively low CO2 concentration, from Earth-like to a few bars.
Lutte pour la terre et lutte pour la Terre dans l’expérience zapatiste
Authors: Baschet Jérôme 
Published: January 2024

L’expérience zapatiste, menée au Chiapas depuis 1994, s’ancre dans la tradition des luttes paysannes pour la terre. Pour Jérôme Baschet, elle a démontré que l’autonomie matérielle, permise par la récupération des terres et la capacité de subsistance qui en découle, est la première condition de l’autonomie politique. Mais l’expérience zapatiste implique aussi un horizon planétaire, marqué par le souci de préserver la possibilité d’une vie digne sur Terre. A la suite de ses précédentes participations à EcoRev’	1 , l’auteur cherche à cerner la façon dont la lutte pour la terre et la lutte pour la Terre s’associent dans l’expérience zapatiste, et se demande dans quelle mesure les conceptions indigènes du rapport au territoire et à cette figure englobante appelée « terre-mère » ont pu jouer un rôle dans l’articulation de ces deux dimensions.

Published: January 2024

Introduction:
Acute coronary syndromes and ischemic stroke have similar risk factors. Risk scores help to identify disease severity in both diseases. We aimed to evaluate if HEART (History, ECG, Age, Risk factors, and Troponin) score could predict re-hospitalization, recurrent cardiac/cerebrovascular events risk, and mortality within 1-year follow-up in patients presenting with acute ischemic stroke.

Methods:
Patients hospitalized with a diagnosis of acute ischemic stroke in our tertiary center between 2019 and 2021 were included in this retrospective study. CHA2DS2-VASc and HEART scores on admission were calculated. In-hospital, 1-month, and 1-year mortalities, as well as re-hospitalization due to recurrent ischemic (cardiac/cerebral), were defined as major adverse cardiac and cerebrovascular events (MACCE), and occurrence of MACCE was accepted as the primary endpoint of the study. Comparative statistical and regression analyses were obtained.

Results:
A total of 297 patients were included. The mortality rate for 30 days was 7.4% and 1 year was 20.5%. HEART and CHA2DS2-VASc scores were found independent risk factors associated with the occurrence of MACCE. Patients who experienced MACCE had higher HEART and CHA2DS2-VASc scores. Meanwhile, HEART score had better prognostic accuracy than CHA2DS2-VASc score when a cutoff value of 3.5 was set, which is associated with 84.7% sensitivity and 75.2% specificity in the prediction of MACCE.

Conclusion:
HEART score is effective in determining re-hospitalization and recurrent cerebral ischemic event risk as well as mortality within 30 days and 1 year in patients presenting with acute ischemic stroke. Thus, concomitant use of HEART and CHA2DS2-VASc scores may provide better characterization of worse prognosis in ischemic stroke patients with high sensitivity and specificity.

Authors: Zhu Jie , Liu Qiping , Zhuang Yuzhong , Wei Ran , Sun Yi , Wang Hao , Song Bin 
Published: January 2024

Background and Aim:
The aim of this study was to investigate the potential value of intracranial carotid artery calcification (ICAC) in therapeutic efficacy and functional outcomes in patients with anterior circulation acute ischemic stroke (AIS) undergoing intravenous thrombolysis.

Materials and Methods:
A total of 207 patients with anterior circulation AIS who underwent intravenous thrombolysis were enrolled in this retrospective study. We divided them into three groups according to thin-slice head noncontrast computed tomography as follows: no ICAC, medial ICAC, and intimal ICAC. The differences in risk factors of different ICAC subtypes were compared, and the effect of ICAC subtype on hemorrhage transformation (HT) after intravenous thrombolysis was also evaluated. Functional outcomes were assessed at 90 days using the modified Rankin Scale.

Results:
Compared to the no and intimal ICAC, patients with the medial ICAC were older and more likely to have diabetes mellitus, hyperlipidemia, previous stroke, and atrial fibrillation. Moreover, the medial ICAC group had a high baseline National Institute of Health Stroke Scale (NIHSS) score and a high incidence of HT. Multivariate logistic regression analysis showed that baseline NIHSS score (odds ratio [OR]: 1.121, 95% confidence interval [CI]: 1.027–1.224) was independently associated with HT. Medial ICAC (OR: 7.418, 95% CI: 1.190–46.231) and baseline NIHSS score (OR: 1.141, 95% CI: 1.042–1.250) were independent risk factors of poor functional outcome at 90 days.

Conclusions:
Medial ICAC could be a new imaging biomarker for predicting functional outcomes in patients with anterior circulation AIS undergoing intravenous thrombolysis. Medial ICAC and baseline NIHSS score were independently associated with poor prognosis at 90 days.

Authors: Priyadarshini K Sangeetha , Nandini V Vidyashree , Marimuthu Russia , Lathief Jailance 
Published: January 2024

Abstract

Background:
3D printing technology is replacing manual fabrication in all fields. 3D-printed impression trays should be assessed as they could replace conventional impression trays in the future.

Aim:
In-vitro comparison and evaluation of the dimensional stability and retention strength of impressions to custom impression trays fabricated using conventional method and additive technology.

Materials and Methods:
A maxillary edentulous auto-polymerizing acrylic resin model served as the master model. Two moulds were prepared from the master model in order to obtain 12 casts. One cast was scanned for 3D printing digital light processing (DLP) and fused deposition modelling (FDM) 24 impression trays using polylactic acid (PLA). Twelve casts were used to fabricate light cure impression trays. Polyvinyl-siloxane impressions were made on the master model using 36 impression trays and 18 trays each were used to assess dimensional stability and retention strength.

Results:
In dimensional stability analysis, one sample t-test revealed a statistically significant difference between each group and the master model followed by a one-way ANOVA. There were significant differences, but the difference was less with FDM trays (P < 0.05). In retention strength analysis, one-way Analysis of variance (ANOVA) revealed statistically significant difference between each group and post-hoc test revealed specific difference, the highest with FDM trays (P < 0.05).

Conclusion:
Dimensional changes were observed at 30 minutes and 72 hours. Lesser dimensional changes were observed when impressions were made using FDM trays followed by DLP and light cure trays. The mean retention strength seen in descending order was FDM, followed by DLP and light cure trays. The best retention strength was noticed when impressions were made using FDM trays.

Authors: Sethi Nandini , Sharma Rohit , Sharma Vinit Kumar , Prajapati Neeraj , Rana Amit Kumar 
Published: December 2023

Introduction:
Eustachian tube (ET) also known as pharyngotympanic tube connects nasopharynx with the middle ear. Evaluation of ET anatomy is aimed in patients with chronic otitis media.

Materials and Methods:
In a study of 53 patients, HRCT Temporal bone was done on 128 dual source simens somatom definition flash machine on 5mm cut section and tympanoplasty was carried out.

Results:
ET angle is one of the important factors for middle ear aeration. Outcome of tympanoplasty at 12th week was 88.7%. In the patients with vertical Eustachian Tube (i.e., more Eustachian Tube angle with the horizontal plane), better graft uptake in tympanoplasty was observed which was statistically significant. However, graft uptake did not correlate with the length of the Eustachian tube.

Conclusion:
It was concluded that on measuring ET length on HRCT, majority of the patients had bony length of 10-12 mm, cartilaginous length of 15-19 mm and total ET length of 28-32 mm. Majority of the patients had ET angle of 21-30 degrees with the hard palate.
Studying the Effect of Maternal Anemia and Neonatal Hematological Indices on Auditory Brainstem Responses of Newborn Babies
Authors: Deepashree Somanahalli Ramachandra , Uppunda Ajith Kumar , Suryanarayana Kumar Gavali 
Published: December 2023

Purpose:
Animal studies have shown the effect of maternal anemia (MA) and neonatal iron deficiency (ID) on the auditory system of young ones. However, the evidence supporting the same in human infants is inconclusive. Hence, the present study aims to investigate the effect of MA and neonatal iron status on the auditory brainstem responses (ABRs) of newborn babies.

Materials and Methods:
A total of 100 babies (gestational age ≥34 weeks) were divided into “Normal” group-57 babies without MA, “Mild” group-22 mild MA babies, and “Moderate” group-21 moderate MA babies. The ABR was recorded using 80 dBnHL click stimuli at 10 and 90 Hz repetition rates.

Results:
The results based on MA showed a significantly better presence of ABR peaks for the normal group than mild and moderate groups at a higher rate and no significant difference for latency and amplitude measures across the groups. The results based on neonatal hematological indices showed that the ABR measures were better in babies with probable ID which could be attributed to neural hyperactivity and an increase in axonal diameter leading to faster nerve conduction velocity.

Conclusion:
The auditory system maturation in newborn babies is influenced by maternal as well as neonatal iron status.

Published: January 2024

Background
Immature hypertrophic scar complicated with contracture, disability, disfigurement, social embarrassment, pain, itching, residual scar, and prolonged maturation period. Various treatments for immature hypertrophic scar are used with limitations for each treatment.

Objective
To evaluate the efficacy and safety of combined fractional carbon dioxide (CO2) and Neodymium-doped Yttrium Aluminum Garnet (Nd:YAG) lasers for the treatment of immature hypertrophic scar both clinically and histopathologically.

Patients and methods
Total of 30 patients with single or multiple immature hypertrophic scars. The single scar was not less than 14 cm in length. In the same patient, single or multiple scars were divided randomly into treated areas and control areas. The treated areas were submitted to 5 sessions of fractional CO2 laser combined with long pulsed Nd:YAG laser, one month in between sessions, the control areas did not receive any treatment. Vancouver Scar Scale (VSS) and patient and observer scar assessment scale (POSAS) were used for clinical evaluation before, 3, and 6 months after treatment. Collagen area percent, elastin area percent, and epidermal thickness were assessed histopathologically before and 3 months after treatment.

Results
The scar areas treated with combined fractional CO2 laser and long pulsed Nd:YAG laser showed superior significant clinical improvement with VSS and POSAS than areas did not receive any treatment (except for the pigmentation parameter of both VSS and POSAS), especially 6 months after last treatment without significant side effects for laser therapy. Opinions of the patients showed superior significant improvement in laser treated areas than areas did not receive any treatment. Epidermal thickness, collagen area percent and elastin area percent showed superior significant improvement in laser treated areas than areas did not receive any treatments three months after last laser session.

Conclusion
Combined treatment of immature hypertrophic scar with fractional CO2 and Nd:YAG lasers is effective, tolerable, and safe.
Periosteal Manifestations of Osteomyelitis and Arthritis on Ultrasound: A Systematic Review
Authors: Waitayangkoon Palapun , Weilg-Espejo Pablo , Kissin Eugene Y. 
Published: January 2024

Abstract
Ultrasound (US) can visualize the periosteal changes in the early stage compared to radiography. In this review, we studied periosteal manifestations on US and assessed their diagnostic utility for osteomyelitis (OM) and arthritis. We included articles that studied ultrasonographic findings of periosteal changes in OM and arthropathies with aims to systematically review periosteal manifestations of each condition and summarize diagnostic values of each finding. A total of 13 articles were included in the systematic review. Of these, 10 articles are on OM, 3 articles are on psoriatic arthritis (PsA), 1 article is on rheumatoid arthritis (RA), and 1 article is on gouty arthritis (GA). In OM, subperiosteal fluid/subperiosteal collection (SF/SC) was detected in 32%–76% within 72 h after presentation. Periosteal reaction (PR) was seen after day 4 and the sensitivity on US ranges from 33% to 100%. In PsA, PR was seen near 16%–59% in active PsA joints. Periosteal changes are rarely detected in RA joints. Small hyperechoic spots were seen in 87.5% of GA. SF/SC may be seen on US as the earliest sign followed by PR for OM. PR is more specific in PsA than RA. Further investigations on periosteal abnormalities on US are warranted to confirm our findings.
Assessment of self-directed learning in the competency-based medical education

Published: January 2024

ABSTRACT
Self-directed learning (SDL) has been acknowledged as a crucial approach in the delivery of medical education. In fact, the goal of lifelong learner defined for a medical graduate cannot be accomplished if the student does not practice SDL. Realizing the importance of SDL in the field of medical education, in the recently adopted competency-based undergraduate curriculum, the regulatory body has clearly specified defined number of hours per year per subject to ensure that provision is created in the curriculum and all the planning is done keeping that in mind. However, the real challenge in the implementation has been the assessment of the SDL, as conventional tools cannot be employed for the same. In general, four different types of assessment methods can be employed, namely, self-assessment, peer assessment, teacher assessment, and external assessment. In conclusion, assessment of SDL sessions is a potential challenge for all the teachers; nevertheless, the adoption of a well-thought approach will surely reduce the apprehensions associated with it and eventually enhance the learning among of the medical students.

ABSTRACT
A 28-year-old patient reported having a lump in the right lower abdominal and pelvic area for the last 21 days, along with pain, anorexia, fever, and nausea. After a thorough investigation, an antero-posterior (AP) scanogram of the patient showed a clearly defined lump in this area. Histopathological examination showed mesenteric fibromatosis. Resection and anastomosis were done. Our case is one of the few known cases of the extremely rare condition fibromatosis of the mesentery. These tumors present a diagnostic and therapeutic difficulty due to their rarity. These tumors are still asymptomatic; however, they frequently appear as an asymptomatic mass. There are not any obvious therapy options. The preferred method of treatment is surgical excision with a wide margin; we underwent the same technique and the prognosis was good. Numerous single case reports with various and peculiar appearances and their difficulties exist. This case report aims to offer the current understanding of mesenteric fibromatosis as well as our clinical experience with the presented patient. Following surgery, the patient did well, and a 3-month follow-up revealed a typical recovery.

Published: December 2023

A healthy lifestyle and illness prevention depend on adequate nutrition, and homestead food production, including home gardening, is one way to increase access and lower the cost of healthy foods. This study was carried out in Odeda Local Government Area of Ogun State to assess the anthropometric indices and knowledge of home gardening of women. The sample size comprised of 170 respondents which were chosen using a multistage sampling technique. Data on sociodemographic, socioeconomic variables, and home gardening knowledge were obtained using an interviewer-administered, well-structured questionnaire. Anthropometric measurements were taken using standard procedures. The nutritional status was assessed using anthropometric measurements. Version 20.0 of Statistical Product and Service Solutions (SPSS) was used to analyze the data. The findings were presented as frequency, percentage, mean, and standard deviation. The threshold for statistical significance was set at p 0.05. The responders were 33.5 years old on average. The majority of respondents (85.3%) had at least a primary education. It was found that 94.7% of the adult women had good knowledge of home gardening, 4.7% had average knowledge, and 0.6% had low knowledge. The nutritional status of the respondents showed that 24.1 percent were overweight, 10.6 percent were underweight, and 10.6 percent were obese. The home garden knowledge score and the anthropometric measurement (BMI) were shown to be significantly associated. The result of this study is an indication that women who are knowledgeable about gardening at home are more likely to have higher nutritional status.
