Influence of Density and Compressive Strength on Intrinsic Air Permeability and Porosity of Hybrid Fibre-Reinforced Lightweight Foamed Concrete
Authors: Anuar Izzat , Ismail Sallehan , Saleh Ani Maslina 
Published: February 2025

Given the growing demand for sustainable and environmentally friendly building materials, lightweight foamed concrete (LFC) is a suitable choice for semi-structural applications. However, the low strength and high water absorption of LFC make it an unsuitable material for large structures. The building industry does not consider LFC cost-effective unless it undergoes strengthening with other materials, as its mechanical strength and durability are insufficient for building use. This paper aims to augment the mechanical and durability characteristics of hybrid fibre-reinforced lightweight foamed concrete (HFRLFC) by using nylon and polypropylene (PP) fibres under a sealed curing condition. A strict experimental method was used to compare HFRLFC to control mixtures (which didn't have any fibres), single-fibre mixtures (0.4% nylon), and hybrid-fibre combinations (0.13% PP and 0.27% nylon) at a constant 1:1 mixing ratio. The findings demonstrated a notable initial improvement in mechanical strength and durability, as well as heightened resistance to lower permeability via less cracking and improved compaction. Mixed HFRLFC with 0.27% nylon and 0.13% PP had better mechanical and long-lasting properties than control mixes and LFC with only nylon fibre. HFRLWC exhibits the synergistic reinforcement mechanisms of hybrid fibres, improving their structural integrity and durability over time. These findings emphasize the potential of HFRLFC as a sustainable and effective material for semi-structural applications.
Maximal Jet Energy of Gamma-Ray Bursts through the Blandford–Znajek Mechanism

Published: February 2025

Abstract
Gamma-ray bursts (GRBs) are among the most energetic events in the Universe, driven by relativistic jets launched from black holes (BHs) formed during the collapse of massive stars or after the merger of two neutron stars. The jet power depends on the BH spin and the magnetic flux accreted onto it. In the standard thin disk model, jet power is limited by insufficient magnetic flux, even when the spin approaches maximum possible value. In contrast, the magnetically arrested disk (MAD) state limits jet energy by extracting significant angular momentum, braking BH rotation. We propose a unified model incorporating both standard thin disk and MAD states, identifying a universal curve for jet power per accretion rate as a function of the magnetic flux ratio,

, at spin equilibrium. For long GRBs (lGRBs), the model predicts a maximum jet energy of ∼1.5% of the accretion energy, occurring at Δeq ∼ 0.4, where the BH equilibrium spin is a ∼ 0.5. Both long and short GRBs are unlikely to be produced by a MAD: for short GRBs, this requires an accreted mass orders of magnitude smaller than that available, while for lGRBs, the narrow progenitor mass distribution challenges the ability to produce the observed broad distribution of jet energies. This framework provides a consistent explanation for both standard and luminous GRBs, emphasizing the critical role of magnetic flux. Both long and short GRBs require magnetic flux distributions that peak around 1027 G cm2.
La métaphysique et avant. Remarque sur la notion d’époque en histoire de la métaphysique
Authors: Carraud Vincent 
Published: February 2025

Les livres de philosophie publiés par Jean-Luc Marion, qu’ils soient historiques (principalement cartésiens ou husserliens) ou phénoménologiques, disent quelque chose. Celui qui fait l’objet de cette étude est méthodologique. Il ne dit donc rien, mais se contente d’énoncer a posteriori des règles qui sont autant de conditions pour énoncer quelque chose en philosophie. Le résumé de ces règles permet de constater combien elles sont devenues aujourd’hui banales : de ce point de vue, le recueil La métaphysique et après, qui reprend des règles décisives quand elles furent énoncées il y a vingt-cinq ans, apparaît à la fois sommaire et indiscutable. On a donc affaire à un recueil d’articles que leur réussite même a rendu inutiles, d’où à la fois sa désuétude et sa validité. Prenant au sérieux le concept d’époque qui figure dans le sous-titre du livre, ce qui requiert de revenir au renouvellement des paradigmes en histoire de la philosophie, la seconde partie de l’étude distingue l’époque (Zeitalter, Epoche) de ce qu’on nomme la période (Zeit­raum), pour montrer que si la périodisation est spécifique, l’épochalisation est totale. Nous en prenons plusieurs exemples, avant de développer deux exemples de la Renaissance française du xiie siècle, réunis dans la recherche de la sagesse sans Métaphysique : d’où la métaphysique et avant.

Published: February 2025

Supernumerary kidney (SK) is an uncommon anomaly of the urinary tract, usually occurring on the left side. A rare case of a partially-fused, SK on the right side is presented. The diagnosis is made through the identification of a distinct pelvicalyceal system along with its supplying renal artery and vein, utilising ultrasound, CT, or MRI.Contribution: Correct diagnosis of partially-fused, supernumerary kidneys based on imaging is crucial to avoid unnecessary procedures, so that asymptomatic cases are managed conservatively.

Authors: Rani Divya Anidharan , Sathyanath Shashwath M. , Karkal Ravichandra , Mendonsa Rohan Dilip , Kakunje Anil 
Published: February 2025

Abstract

Background:
Bipolar disorder is a chronic mental disorder characterized by mania and depression with intervening periods of euthymia. Although cognitive impairments are associated with acute episodes, these do seem to persist in lower degree during periods of euthymia.

Aim:
The objective was to study cognitive functions and psychosocial functioning among euthymic patients with bipolar mood disorder, to correlate the same with sociodemographic and clinical characteristics, and finally, to compare cognitive function disorder with those of apparently healthy controls.

Settings and Design:
A cross-sectional comparative study was conducted among patients in the department of psychiatry of a tertiary care center in Karnataka, India.

Materials and Methods:
Thirty euthymic patients with bipolar mood disorder were selected using the Young Mania Rating Scale and Hamilton Depression Rating Scale screening and compared with 30 healthy controls who were screened using the General Health Questionnaire-12 for cognitive function and psychosocial functioning. Sociodemographic and clinical data were collected using a standard questionnaire. Trail making test, digit symbol substitution test, visual memory test, and digit span test were used to assess cognitive function. Functioning assessment short test was used to assess psychosocial functioning. Chi-square test, “t”- test, and Pearson’s correlation were used to analyze the data.

Results:
Compared to controls, cases took significantly more time for visual attention and task switching (P = 0.001), had poorer psychological functioning and speed (P = 0.001), and had poorer memory (P = 0.001). The number of episodes (depression/mania) was negatively correlated with psychomotor speed (P = 0.001), verbal working memory/attention (P = 0.049), and visual memory test (P = 0.031), respectively, and positively correlated with time taken for psychomotor functioning of cases (P = 0.001). Age of onset and reduction of psychomotor speed (P = 0.031) were positively correlated.

Conclusions:
Patients with bipolar disorder exhibited cognitive and psychosocial impairments during euthymic period. These impairments were correlated with number of episodes and age of onset.
Need Assessment of Patients and their Primary Caregivers among Various Psychiatric Illnesses in a Tertiary Care Hospital in Gujarat: A Cross-sectional Study
Authors: Tanvi G. Kacha , Vishnubhai Patel Hardik , Bhaveshkumar M. Lakdawala 
Published: February 2025

Abstract

Background:
The concept of “needs” helped in understanding the mismatch between the demands of patients with severe psychiatric illnesses (PSPI) and their primary caregivers (PCs) with the services provided to them. Therefore, nowadays, “needs” has been evaluated as a measure of outcome among PSPI.

Aims:
The aim of this study was to assess the healthcare needs (HCN) of the PSPI perceived by themselves and their PC.

Materials and Methods:
This cross-sectional study was performed on 109 PSPI and their PC who fulfilled inclusion and exclusion criteria. HCN was assessed by the Camberwell Assessment of Need – R (CAN – R) and Supplementary Need Assessment (SNA) Questionnaire. Statistical analysis was done by Excel. Student’s t-test and Pearson’s correlation coefficient were used for further analysis. P < 0.05 was considered statistically significant.

Results:
More than two-thirds (~72%) of needs were met and less than one-third (~28%) of needs were unmet according to PSPI and PC assessed on CAN-R. As per SNA, less than half (44%) of needs were met and more than half (56%) of needs were unmet according to PSPI and PC. The most reported unmet HCN were social needs, rehabilitation facilities, and benefits from the government. The most reported met HCN were related to environmental needs, needs related to basic healthcare facilities and support from PC.

Conclusion:
As per CAN-R less than one-third of needs were unmet and as per SNA, more than half of needs were unmet. Therefore, the government, health care sectors, policies, and mental health institutes should pay more attention to providing HCN as per SNA.
Prevalence of Anemia in Women Admitted to Psychiatry Inpatient Unit of a General Hospital in South India: A Retrospective Observational Study
Authors: Chopra Akanksha , Kantipudi Suvarna Jyothi 
Published: February 2025

Abstract

Introduction:
Anemia is a common condition that can adversely affect both physical and mental health. Individuals with psychiatric disorders may be particularly vulnerable due to various factors, including inadequate nutrition, poor healthcare access, and the physiological effects of their illness or treatment. This study aimed to evaluate the prevalence and severity of anemia among female psychiatric patients and explore its association with socio-demographic and clinical variables.

Methodology:
A cross-sectional retrospective study design was used to analyse the medical records of 253 female patients admitted to a psychiatric hospital. Data included clinical details, laboratory findings, and demographic information collected during their hospital stay.

Results:
The prevalence of anemia in this sample was notably high at 70.75%, with 7.9% of the participants having severe anemia. The study identified microcytic anemia as the most prevalent morphological subtype. Women with severe mental illness (SMI) had significantly lower hemoglobin levels and higher rates of moderate and severe anemia compared to those with common mental illness (CMI).

Conclusion:
These findings reveal a substantial burden of anemia among female psychiatric patients, especially those with severe mental illness. This underscores the importance of routine anemia screening, nutritional counseling, and integrative healthcare approaches for psychiatric populations. Early intervention strategies focusing on nutritional education and anemia management could play a pivotal role in improving both physical and mental health outcomes for this at-risk group.
Pectoral nerve block and pecto-intercostal fascial block versus thoracic paravertebral block for postoperative analgesia in modified radical mastectomy: A randomised controlled trial
Authors: Sheshagiri Adarsh M , Kumar Ajeet , Sinha Chandni , Kumar Abhyuday , Kumari Poonam , Kumar Amarjeet , Jha Chandan 
Published: February 2025

Background and Aims:
Modified radical mastectomy (MRM) is associated with persistent postoperative pain. Paravertebral block (PVB) is the gold standard for postoperative analgesia. A pecto-intercostal fascial plane (PIFB) block added to the pectoral nerve block (Pecs) may provide effective analgesia. This trial aimed to compare the analgesic efficacy of Pecs-PIFB with PVB.

Methods:
Fifty American Society of Anesthesiologists (ASA) I/II patients scheduled for MRM were randomly assigned to receive either Pecs-PIFB block with 30 mL for Pecs block and 15 mL for PIFB or PVB block with 20 mL (0.2% ropivacaine). Postoperatively, intravenous (IV) morphine was administered through a patient-controlled analgesia (PCA) pump. The primary outcome was to compare the time to the first demand dose of rescue analgesic. The secondary outcomes were postoperative 24-hour opioid consumption, pain scores (30 mins and 1, 2, 4, 6, 12, and 24 h), patient satisfaction score (24 h), and block-related complications. The unpaired t-test compared quantitative normally distributed data, while the Mann-Whitney U test compared quantitative discrete data. A P value < 0.05 was considered to be statistically significant.

Results:
Patients in the Group Pecs-PIFB had an increased median time to first demand dose: 440 [interquartile range (IQR): 360–540] versus 340 (IQR: 180–360) minutes (P = 0.019) and lower median 24-h postoperative morphine consumption: 4 (3–6) versus 6 (4–8) mg (P = 0.020). Patients in the Group Pecs-PIFB had better pain scores at 30 minutes and 1 h.

Conclusion:
Compared to thoracic PVB, the combination of Pecs and PIFB block prolonged the duration of analgesia and decreased postoperative opioid consumption in patients undergoing MRM surgeries. There was no statistical increase in complications in patients receiving this block.

Authors: Sharma Vikas , Pandey Sandhya , Gupta Gaurav , Gandhi Ajeet , Rastogi Madhup , Sethi Rohini , Beena Sachan 
Published: February 2025

Abstract

Context:
Oncoplastic breast surgery is the current standard for treatment of early breast cancer, offering a balance between good cosmetic outcomes and limited risk of locoregional recurrence. Still, the best technique of reconstruction for centrally located breast cancer (CLBC) is not established because of cosmetic issues associated with NAC resection and difficulties associated with its reconstruction.

Aims:
This study aims to present here a novel technique of post-BCS breast reconstruction for CLBC by latissimus dorsi (LD) flap coupled with immediate NAC reconstruction using modified Skate Flap.

Methods and Material:
A total of 9 patients underwent oncoplastic breast reconstruction using the described technique for CLBC at our center from July 2018 to March 2020. Postoperative analysis was done for surgical complications, pathological, oncological, and cosmetic outcomes. QOL outcome was assessed using body image scale (BIS) and compared with another group of 9 mastectomy patients operated in the same time period.

Statistical Analysis:
The analysis was done using SPSS software. P value was calculated using the Independent t-test.

Results:
Mean BIS score was 4.44 (range 1–8) in BCS vs 20 (range 11–27) in the mastectomy group, signifying better QOL in the BCS group. The postoperative cosmetic results, as evaluated by the patients, were excellent in 7 of 9 patients (77.77%), good in 1 patient (11.11%), and fair in 1 (11.11%), with an overall mean of 4.11 equivalent to 82% satisfaction.

Conclusions:
Immediate reconstruction with LD flap and modified skate flap following resection of CLBC is a good technique for this difficult group of patients to be managed by BCS. Cosmetic results of this technique are satisfactory. Additionally, it avoids the need for a symmetrizing contralateral breast surgery as well as a second surgery on the ipsilateral breast.

Published: February 2025

Abstract

Objective:
The aim of this study was to explore the diagnostic accuracy of ultrasound-guided (US-guided) percutaneous needle biopsy (PNB) and related influencing factors that could provide references for clinicians to improve the diagnostic accuracy of peripheral pulmonary lesions (PPLs).

Methods:
We retrospectively analyzed 318 consecutive cases with PPLs who underwent US-guided PNB successfully in Chongqing Red Cross Hospital, Fusheng Community Health Service Center, Maoershi Community Health Service Center, and Yuzui Community Health Service Center. We collected pathological results of ultrasound-guided biopsy, clinical final diagnosis, disease course records, and postoperative complications of these patients. According to whether the pathological diagnosis of biopsy of US-guided PNB was consistent with the final clinical diagnosis, it can be divided into true positive, false positive, true negative, and false negative to calculate diagnostic yield. The factors affecting the diagnostic accuracy were assessed between diagnosed cases (true positive and true negative) and non-diagnosed cases (false negative and uncertain) by the Chi-Square test.

Results:
Among the 318 patients, 292 cases had determinate pathological diagnosis through US-guided PNB and 26 cases were indeterminate. The diagnostic yield including diagnostic accuracy, sensitivity, specificity, positive-predictive value, and negative predictive value in 318 patients under US-guided PNB was 86.2%, 73.8%, 85.2%, 82.7%, and 77.3%, respectively. The total complication rate was 6.0%. After analyzing multiple factors during the biopsy process, we found that the size of lesion had a significant impact on the diagnostic accuracy of US-guided PNB.

Conclusion:
Ultrasound-guided percutaneous needle biopsy has a high success rate and diagnostic accuracy, which is an effective and accurate method for the diagnosis of peripheral lung diseases. The size of lesions can affect the diagnostic accuracy.
Relationship between surgical compliance and survival outcome in patients with Ewing sarcoma
Authors: Chen Bin , Li Hong-Zhuo , He Xiao-Feng 
Published: February 2025

Abstract

Background:
The impact of surgical compliance on survival outcomes in patients with Ewing sarcoma (ES) is unclear, so this study was performed to explore the association between them.

Methods:
We used the SEER*Stat software (version 8.3.6.1) to extract information on ES patients from the SEER database. Patients were divided into two groups based on their adherence to surgical recommendations: the surgical compliance group and the surgical noncompliance group. Categorical variables were expressed as percentages. Multivariate logistic regression and Chi-square test were used to explore variables related to surgical compliance. Univariate Cox regression analysis was used to initially select potential prognostic factors, and then the factors selected in the univariate Cox regression analysis were further analyzed in a multivariate Cox proportional risk model to ultimately determine the risk prognostic factors significantly related to the survival of patients with ES.

Results:
Multiple logistic regression analysis suggested that adults (OR = 0.373, 95% confidence interval (CI): 0.164–0.849), Grade IV (OR = 0.373, 95% CI: 0.164–0.849), and unmarried patients (OR = 0.568, 95% CI: 0.339–0.954) were more inclined to accept surgery recommendations, while patients from 2001 to 2010 were less compliant with surgery. Multifactorial Cox regression analysis suggested that surgical compliance was an independent prognostic factor for patients with ES. Through the Kaplan-Meier survival curves, we could clearly observe that the overall survival was higher in the surgical compliance group than in the surgical noncompliance group. Furthermore, subgroup analysis also reached similar conclusions.

Conclusion:
In this study, we found that surgical compliance was an independent predictor of patient prognosis. Furthermore, we found that age, tumor grade, year of diagnosis, and marital status may be related to surgical compliance.

Published: February 2025

Abstract

Objective:
Our objective was to evaluate the impact of the use of a sealing device during inguinofemoral lymphadenectomy on the reduction of postoperative complications.

Methods:
A single-institution, prospective, nonrandomized study was carried out. Fifteen patients with vulvar cancer underwent wide excision and inguinal lymphadenectomy between May 2017 and April 2019. Five patients underwent lymphadenectomy with a bipolar sealing device, whereas the remaining 10 patients received the standard procedure. Postoperative complications including wound infection, seroma, and lymphedema were selected as the primary outcome.

Results:
Patients who underwent surgery using a sealing device showed significantly lower wound infection rate (0 cases, 0%) compared with patients who underwent the standard procedure (7 cases, 70%; P = 0.026). Incidence of seroma and lymphedema did not show statistically significant differences between groups.

Conclusions:
The use of a sealing device to perform the inguinofemoral lymphadenectomy in vulvar cancer could reduce the rate of wound infection compared with the standard procedure.

Published: February 2025

Abstract
Chronic myeloid leukemia is a myeloproliferative neoplasm which can present in chronic phase, accelerated phase, or blast crisis. Most of the children present in chronic phase. Tyrosine kinase inhibitors are used as a targeted therapy. Few children progress to blast crisis on therapy. The blast crisis occurs in the marrow. Very few cases are reported in adults with isolated central nervous system (CNS) blast crisis. Here we are reporting a rare case of isolated CNS relapse in a child.
