Abstract
Background
Hyperandrogenism is frequently found in polycystic ovary syndrome (PCOS) and contributes to physical manifestations like hirsutism and obesity, along with infertility. This condition can result in anxiety, depression, and body image disorders, potentially leading to sexual dysfunction. The objective of this investigation was to assess the correlation among hirsutism, anthropometric characteristics, sexual dysfunction, and anxiety levels among infertile Indonesian women diagnosed with PCOS.

Methods
From December 2021 to December 2022, a cross-sectional study was undertaken involving 71 infertile women diagnosed with PCOS at Yasmin Clinic, Dr. Cipto Mangunkusumo General Hospital in Jakarta, Indonesia. Hirsutism was assessed using the modified Ferriman-Gallwey (mFG) score; the anthropometric profile was assessed using BMI and waist-to-hip ratio. The assessment of sexual dysfunction was conducted using the Female Sexual Function Index (FSFI) questionnaire, while the evaluation of anxiety levels utilized the HAM-A questionnaires.

Results
In this study, it was discovered that 53.3% of subjects experienced sexual dysfunction. However, there was no statistically significant relationship between hirsutism, anthropometric profile, and sexual dysfunction score in infertile women with PCOS (p > 0.05). Analysis of the overall FSFI domain score revealed that lubrication and satisfaction were lower in obese patients (p = 0.02 and p = 0.03), but this did not contribute to an overall sexual dysfunction score. Also, we found that subjects who experienced sexual dysfunction had a higher anxiety score (p < 0.005), with correlation analysis showing that Ferriman-Gallwey (FG) scores have a significant positive correlation with anxiety.

Conclusion
There is no correlation between hirsutism, anthropometric profile, and sexual dysfunction in infertile Indonesian women diagnosed with PCOS. However, hirsutism could play a role in causing anxiety in Indonesian PCOS women. Additional investigation is required, as female sexual function is an intricate subject.

Abstract
Background
This study explores the effectiveness of ultrasonography (USG)-guided saline enema reduction for ileocecal intussusception. It investigates factors, ascertainable through physical examination, ultrasound, and medical history, that impact the success of the procedure and the likelihood of recurrence.

Results
Conducted at a tertiary referral center, the study included 323 pediatric cases diagnosed with intussusception between 2017 and 2023. Patient data, symptoms, signs, and outcomes were collected. Hydrostatic saline enema, performed under USG guidance, served as the primary non-operative treatment. Logistic regression models assessed the impact of clinical factors on success and recurrence rates. Out of 323 patients examined for eligibility, 184 met inclusion criteria and were analyzed. Successful reduction with saline enema was achieved in 86.7%. In-hospital recurrence occurred in 17.1%, notably higher for intussusceptions extending into the rectum (p < 0.03). Pathologic lead point was identified in 33.3% of operated cases. The study revealed a correlation between the increasing number of symptoms (p < 0.001) and reduced success rates in enema reduction, with vomiting (p < 0.02), diarrhea (p < 0.05), and peritoneal fluid (p < 0.008) negatively affecting outcomes. Symptom duration of 1–9 h (p < 0.001) and 10–24 (p < 0.01) correlated with higher success rates, but prolonged symptom duration of > 24 (p = 0.4) and 48–72 (p = 0.2) hours did not decrease chances for successful reduction.

Conclusions
Prolonged symptom duration of over 24 and 48–72 h should not be a definitive contraindication for non-operative treatment. Cumulation of symptoms typical for intussusception might reduce the chances of success. These findings contribute valuable insights into optimizing non-operative strategies for managing pediatric intussusception.

Published: April 2024

Abstract
Background
Cervical spondylotic myelopathy (CSM) is the most prevalent form of dysfunction in the cervical cord. For best results, CSM must be identified and treated quickly, before spinal cord injury develops. We aimed at determining the diagnostic value of quantitative and qualitative diffusion tensor imaging (DTI) indices in the assessment of CSM. Thirty patients were included in this prospective study with clinically suspected CSM of both sexes. This study aimed at determining the diagnostic value of quantitative and qualitative DTI indices in early assessment of CSM and subsequently early and proper management decision rendering better clinical outcome.

Results
This prospective study included 30 patients: with clinically suspected CSM with a mean age of 51.88 ± 10.28 years. Patients with CSM were graded to 3 grades, mild (No. = 17), moderate (No. = 13) and severe (No. = 0) according to the modified Japanese orthopedic association (mJOA) grading system. Correlation test was performed between mJOA grades of severity with fractional anisotropy (FA), apparent diffusion coefficient (ADC) and T2 cord signal. We found a negative correlation between ADC and FA with Spearman’s rho value of − 0.612 and “P value 0.000” (P value < 0.05), a positive correlation between FA with mJOA clinical score with Spearman’s rho value of − 0.504 & “P value 0.036” (P value < 0.05) and a negative correlation between ADC and mJOA clinical score with Spearman’s rho value of 0.385 and P value 0.005 (P value < 0.05), and no significant correlation was found between mJOA clinical score and T2 hyperintense signal with Spearman’s rho value of − 0.304 and “P value 0.102” (P value < 0.05). Qualitative maps grading by 3D tractography images were done, and 18 patients in the study (60%) showed homogenous intact fiber tracts (grade I), 9 patients (30%) showed reduction or alteration of anisotropy or mixed colors intensity (grade II), and 3 patients (10%) showed fiber tract disruption or displaced cord (grade III). Three DTI parameters (other than FA and ADC) were measured, and two of them show significant difference between their measures in the stenotic and non-stenotic portions of the spinal cord—RA (P value = 0.00) and RD (P value = 0.00).

Conclusions
We concluded that DTI is a crucial tool for early diagnosis and grading of CSM (cervical spondylosis myelopathy)—quantitatively and qualitatively—hence, it should be routinely integrated with conventional cervical spine MRI in case of clinically or radiologically suspected cervical cord compression, as the FA parameter together with the clinical assessment formulates the management plan decision for the CSM whether surgical or non-surgical and depicts the need for early surgical decision rendering better clinical outcome compared to that based on T2 hyperintense cord signal.

Published: April 2024

Abstract
Background
Amelanotic/hypomelanotic melanoma is an extremely rare cancer and accounts for less than 1/10,000 in the population. For losing and hypomelanotic pigment, amelanotic melanoma can lead to misdiagnosis with benign skin lesions. Therefore, early recognition and diagnosis is important to avoid a delay in treatment.

Case presentation
A 73-year-old man presented for a gradually enlarged nodule on the surface skin of the left crus, with no color change, ulceration, or bleeding. Malignant lesion was suspected based on computed tomography (CT) and magnetic resonance imaging (MRI), and biopsy was scheduled. Immunohistochemical (IHC) revealed amelanotic melanoma followed by biopsy.18Florine-fluoro-2-deoxy-2-d-glucose (18F-FDG) positron emission tomography-computed tomography (PET-CT) was employed to explore whether there are metastases or not. 18F-FDG PET-CT showed increased FDG accumulation with standardized uptake value max (SUVmax) of 5.6 of the lesion, and no other lesions were detected. The patient refused to be hospitalized and died 12 months later.

Conclusion
This case highlights the need of considering melanoma even if there is no color change. Increased FDG uptake from PET-CT is prone to be consistent with malignant disease as well as whole body scan is crucial in determining the accurate TNM stage. Moreover, prompt treatment according to guidelines is necessary even if the disease is at its early stage.

Published: April 2024

Abstract
Context
Children with human immunodeficiency virus (HIV) infection frequently present with opportunistic infections of the lung that may be associated with high mortality rate. There is no study, to the best of our knowledge, correlating specific radiographic patterns of chest infections with CD4 levels of immunity in HIV-infected children of Indian subcontinent (where prevalence of respiratory tuberculosis is very high).

Aims
To study the radiological patterns of chest infections in HIV-infected children, and to correlate these radiological findings with CD4 cell count and final diagnosis.

Methods
Forty-five HIV-infected children (1–18 years of age) with suspected chest infections were included in the study. The baseline and the most recent CD4 counts were recorded for each patient. Chest X-ray (CXR) was obtained in all the patients, and multi-detector computed tomography (MDCT) chest was done in 27 patients having clinical suspicion of infection with normal or equivocal findings on CXR. Chest radiographs and MDCT chest were analyzed for different radiological patterns of chest infections. Imaging findings were correlated with CD4 count range for disease spectrum. The final etiopathological diagnosis was achieved in combination with clinico-radiological findings, laboratory data, cytohistopathology and follow-up imaging.

Results
Out of 45 children confirmed to be HIV-infected, 27 (60%) had bacterial infection, 14 (31.11%) had tuberculosis, and four (8.89%) had fungal infection.
Consolidation on CXR/CT strongly suggested bacterial etiology (P < 0.05). Mediastinal/hilar lymphadenopathy (with or without necrosis) strongly suggested tubercular etiology (P value < 0.05). Diffuse GGO/haziness on CXR/CT strongly suggested fungal etiology (P value < 0.05).
On correlation with CD4 count (cells/mm3), the bacterial infections occurred at early stages of HIV infection when immune status was relatively preserved, and most of the patients with tubercular infection had moderate immunosuppression. On the other hand, all patients of fungal infection showed severe immunosuppression.

Conclusion
A wide spectrum of pulmonary disease encountered in HIV-infected children warrants an integrated approach of image interpretation. Familiarity with the imaging patterns, combined with relevant clinical/laboratory details, may greatly help to improve the diagnostic confidence and to reach to a more meaningful differential diagnosis.
The value of adding T2 mapping sequence to the routine MRI protocol in the evaluation of cartilage lesions of the ankle joint
Authors: Mostafa Alaa , Mohamed Ahmed Mostafa , Osman Ahmed Mohamed , Hossam El Din Nourhan Mohammed 
Published: April 2024

Abstract
Background
Ankle joint cartilage injury is frequently associated with degenerative changes, even in the absence of symptoms. Earlier treatment of cartilage damage with joint preservation is clearly more successful. The main limitation of morphologic cartilage magnetic resonance imaging sequences is that they are not very sensitivity in the detection of early cartilage degeneration. Recent advances in biochemical magnetic resonance imaging have yielded sequences that are sensitive to molecular changes in the composition of cartilage matrix. This includes water- and collagen-sensitive T2\T2* mapping. The aim of this study was to determine the extent of improvement of the diagnostic performance of routine magnetic resonance imaging protocol in the evaluation of ankle joint articular cartilage lesions following the addition of a T2 mapping sequence.

Results
A total of 45 cases, 30 patients (12 male and 18 female) and 15 controls (10 male and 5 female) who underwent routine ankle magnetic resonance imaging with additional T2 mapping sequence, were included in the study. Out of 30 patients, four patients were misdiagnosed as being normal, while having changes of cartilage composition of early degenerative changes, discovered by T2 mapping sequence. The patients group as well as the-control groups had significantly higher T2-values in the superficial cartilage layer (P < 0.001) compared to the deep layer. When comparing between the medial and the lateral compartments at patients group, the T2-relaxation times were more pronounced in the medial talar cartilage compartment compared to the lateral talar cartilage compartment.

Conclusions
Magnetic resonance imaging can observe not only the destruction of the structural integrity but also the change of the components in articular cartilage. In this study, the addition of a T2 mapping of the ankle cartilage sequence to a routine MR ankle protocol improved sensitivity and accuracy in the detection of early cartilage lesions within the ankle joint.
Affordances of Fantasy
Authors: Attebery Brian 
Published: April 2024

Abstract
Each of the functions of fantasy described by J. R. R. Tolkien in his essay “On Fairy-Stories” can be reframed through affordance theory into a kind of re-visioning. Such re-visioning is comparable to the formalist notion of defamiliarization or the science fiction technique that Darko Suvin called “cognitive estrangement.” Whereas science fiction projects alternative futures, fantasy's affordances allow writers to generate alternative worldviews grounded in real or invented mythic pasts. The initial move away from claiming to imitate reality allows fantasy writers to project inner experience onto an outer storyworld (there is no pathetic fallacy in fantasy), to depict multiple contradictory selves (housed within a single body or spread out over several characters), and to invite readers to consider alternatives to commonsense assumptions and seemingly inevitable social orders.
KATANIN-mediated microtubule severing is required for MTOC organisation and function in Marchantia polymorpha
Authors: Attrill Sarah T. , Dolan Liam 
Published: April 2024

ABSTRACT
Microtubule organising centres (MTOCs) are sites of localised microtubule nucleation in eukaryotic cells. Regulation of microtubule dynamics often involves KATANIN (KTN): a microtubule severing enzyme that cuts microtubules to generate new negative ends, leading to catastrophic depolymerisation. In Arabidopsis thaliana, KTN is required for the organisation of microtubules in the cell cortex, preprophase band, mitotic spindle and phragmoplast. However, as angiosperms lack MTOCs, the role of KTN in MTOC formation has yet to be studied in plants. Two unique MTOCs – the polar organisers – form on opposing sides of the preprophase nucleus in liverworts. Here, we show that KTN-mediated microtubule depolymerisation regulates the number and organisation of polar organisers formed in Marchantia polymorpha. Mpktn mutants that lacked KTN function had supernumerary disorganised polar organisers compared with wild type. This was in addition to defects in the microtubule organisation in the cell cortex, preprophase band, mitotic spindle and phragmoplast. These data are consistent with the hypothesis that KTN-mediated microtubule dynamics are required for the de novo formation of MTOCs, a previously unreported function in plants.
Identification of 30 transition fibre proteins in Trypanosoma brucei reveals a complex and dynamic structure
Authors: Ahmed Manu , Wheeler Richard , Týč Jiří , Shafiq Shahaan , Sunter Jack , Vaughan Sue 
Published: April 2024

ABSTRACT
Transition fibres and distal appendages surround the distal end of mature basal bodies and are essential for ciliogenesis, but only a few of the proteins involved have been identified and functionally characterised. Here, through genome-wide analysis, we have identified 30 transition fibre proteins (TFPs) and mapped their arrangement in the flagellated eukaryote Trypanosoma brucei. We discovered that TFPs are recruited to the mature basal body before and after basal body duplication, with differential expression of five TFPs observed at the assembling new flagellum compared to the existing fixed-length old flagellum. RNAi-mediated depletion of 17 TFPs revealed six TFPs that are necessary for ciliogenesis and a further three TFPs that are necessary for normal flagellum length. We identified nine TFPs that had a detectable orthologue in at least one basal body-forming eukaryotic organism outside of the kinetoplastid parasites. Our work has tripled the number of known transition fibre components, demonstrating that transition fibres are complex and dynamic in their composition throughout the cell cycle, which relates to their essential roles in ciliogenesis and flagellum length regulation.
Knowledge-attitude and practice of Anthrax and brucellosis: Implications for zoonotic disease surveillance and control in pastoral communities of Afar and Somali region, Ethiopia
Authors: Tschopp Rea , Kidanu Ashenafi GebreGiorgis 
Published: April 2024

Background
Anthrax and brucellosis are endemic national priority zoonotic diseases in Ethiopia. This study assess the possible factors explaining the current limited information available on animal and human cases in pastoral communities.

Methods
Two questionnaire surveys gathered data from 509 pastoralists and 51 healthcare providers between February and April 2019 in five districts of Afar and the Somali region (SRS).

Results
Among the 51 healthcare providers, 25 (49%) and 38 (74.5%) had heard of brucellosis, and anthrax, respectively. Of those, only 3 (12%) and 14 (36.8%) knew the symptoms of brucellosis and Anthrax. None of the Health Extension Workers knew any disease symptoms. Healthcare providers recalled two human cases of brucellosis and 39 cases of Anthrax in the last 12 months, based on symptom-based diagnosis. Pastoralists had a moderate level of knowledge about diseases in their animals, with over half (52.4%; n = 267/509) understanding that animals can transmit diseases to people. Overall, 280 out of 508 (55.1%) and 333 out of 507 (65.7%) pastoralists had heard of brucellosis and Anthrax, respectively. Among the latter, 282 (51.3%) knew at least one preventive measure for Anthrax. However, disease knowledge among women was poor. Despite their knowledge, pastoralists engaged in risky unprotected animal handling, animal product consumption/usage as well as husbandry behaviors exposing them to pathogens and favoring the spread of diseases. They identified Anthrax as the most important zoonosis (47.6%) and as one of top three diseases suspected to cause mortality in their livestock. Pastoralists highlighted lack of vaccine coverage, availability and their timely administration. Both, pastoralists and healthcare providers stated the lack of disease awareness and the unavailability of drugs in the market as important challenges. Health facilities lacked protocols and standard operating procedures for managing zoonotic diseases, and did not have access to laboratory confirmation of pathogens.

Conclusion
Our study revealed significant under-reporting of Anthrax and brucellosis, and weak prevention and response in humans, mostly associated with poor disease knowledge of healthcare providers. Ability to respond to animal outbreaks was limited by vaccine and drugs availability, timely vaccine administration and the mobility of pastoralists.
Accessibility of intimate partner violence-related services for young women in Spain. Qualitative study on professionals’ perspectives

Published: April 2024

Introduction
Intimate partner violence (IPV) is common among young people, but the use of IPV resources among young adult women and teenagers is limited. This study aims to analyze professionals’ perceptions about the main barriers and facilitators encountered by young women (16–29 years old) exposed to intimate partner violence (IPV) when accessing formal services in Spain.

Methods
Qualitative study based on 17 in depth interviews carried out in 2019 with professionals who manage resources for IPV care in Madrid (Spain) from different sectors (social services, health care, security forces, women or youth issues offices, associations). A qualitative content analysis was conducted.

Results
The professionals interviewed perceive the following barriers: 1) Time it takes for young women to recognize IPV because the social construction of sexual-affective relationships is permeated by gender inequality; 2) The process of leaving a situation of abuse; 3) Barriers inherent to IPV services. The key aspects to improve access to these resources are related to care services, professional practice, and the young women themselves.

Conclusions
There are both psychosocial barriers, derived from the process of leaving a situation of violence, as well as structural barriers for young women to access and properly use the recognized services specifically aimed at them or comprehensive IPV care. Services need to be tailored to the needs of young women so they can be truly effective in order to escape IPV.

Authors: Milton-Cole R. , Goubar A. , Ayis S. , O’Connell M. D. L. , Kristensen M. T. , Schuch F. B. , Sheehan K. J. 
Published: April 2024

Purpose
The aim was to compare the probability of discharge after hip fracture surgery conditional on being alive and in hospital between patients mobilised within and beyond 36-hours of surgery across groups defined by depression.

Methods
Data were taken from the National Hip Fracture Database and included patients 60 years of age or older who underwent hip fracture surgery in England and Wales between 2014 and 2016. The conditional probability of postsurgical live discharge was estimated for patients mobilised early and for patients mobilised late across groups with and without depression. The association between mobilisation timing and the conditional probability of live discharge were also estimated separately through adjusted generalized linear models.

Results
Data were analysed for 116,274 patients. A diagnosis of depression was present in 8.31% patients. In those with depression, 7,412 (76.7%) patients mobilised early. In those without depression, 84,085 (78.9%) patients mobilised early. By day 30 after surgery, the adjusted odds ratio of discharge among those who mobilised early compared to late was 1.79 (95% CI: 1.56–2.05, p<0.001) and 1.92 (95% CI: 1.84–2.00, p<0.001) for those with and without depression, respectively.

Conclusion
A similar proportion of patients with depression mobilised early after hip fracture surgery when compared to those without a diagnosis of depression. The association between mobilisation timing and time to live discharge was observed for patients with and without depression.
