AimsKnowledge on total knee arthroplasties (TKAs) in patients with a history of poliomyelitis is limited. This study compared implant survivorship and clinical outcomes among affected and unaffected limbs in patients with sequelae of poliomyelitis undergoing TKAs.MethodsA retrospective review of our total joint registry identified 94 patients with post-polio syndrome undergoing 116 primary TKAs between January 2000 and December 2019. The mean age was 70 years (33 to 86) with 56% males (n = 65) and a mean BMI of 31 kg/m2 (18 to 49). Rotating hinge TKAs were used in 14 of 63 affected limbs (22%), but not in any of the 53 unaffected limbs. Kaplan-Meier survivorship analyses were completed. The mean follow-up was eight years (2 to 19).ResultsThe ten-year survivorship free from revision was 91% (95% confidence interval (CI) 81 to 100) in affected and 84% (95% CI 68 to 100) in unaffected limbs. There were six revisions in affected limbs: three for periprosthetic femoral fractures and one each for periprosthetic joint infection (PJI), patellar clunk syndrome, and instability. Unaffected limbs were revised in four cases: two for instability and one each for PJI and tibial component loosening. The ten-year survivorship free from any reoperation was 86% (95% CI 75 to 97) and 80% (95% CI 64 to 99) in affected and unaffected limbs, respectively. There were three additional reoperations among affected and two in unaffected limbs. There were 12 nonoperative complications, including four periprosthetic fractures. Arthrofibrosis occurred in five affected (8%) and two unaffected limbs (4%). Postoperative range of motion decreased with 31% achieving less than 90° knee flexion by five years.ConclusionTKAs in post-polio patients are complex cases associated with instability, and one in four require constraint on the affected side. Periprosthetic fracture was the main mode of failure. Arthrofibrosis rates were high and twice as frequent in affected limbs.Cite this article: Bone Joint J 2023;105-B(6):635–640.

AimsThe aim of this study was to investigate the outcomes of arthroscopic decompression of calcific tendinitis performed without repairing the rotator cuff defect.MethodsA total of 99 patients who underwent treatment between December 2013 and August 2019 were retrospectively reviewed. Visual analogue scale (VAS) and American Shoulder and Elbow Surgeons (ASES) scores were reviewed pre- and postoperatively according to the location, size, physical characteristics, and radiological features of the calcific deposits. Additionally, the influence of any residual calcific deposits shown on postoperative radiographs was explored. The healing rate of the unrepaired cuff defect was determined by reviewing the 29 patients who had follow-up MRIs.ResultsStatistically significant improvement from pre- to postoperation was seen in all VAS and ASES scores for each group, but no statistical differences were seen between the postoperative scores according to the differences in the features of the calcific deposits. When residual calcification was observed postoperatively, the mean ASES and VAS (rest) scores improved significantly to 95.0 (SD 5.6) and 0.0 (SD 0.0), respectively (p = 0.006 and p < 0.001), and did not differ from those who had the complete removal. Of 29 patients who had follow-up MRIs, six (20.7%) showed signs of an interstitial tear. This group’s mean postoperative ASES and VAS (rest) scores improved to excellent levels of 96.0 (SD 3.7) and 0.0 (SD 0.0), respectively, and were similar to those of the 23 patients with normal MRI appearances.ConclusionArthroscopic removal of calcific deposits without repairing the rotator cuff defect resulted in significant improvement in function and pain level, regardless of the deposit’s location, size, type, and whether or not complete excision was achieved. Despite leaving the defects unrepaired, in the limited number of patients with follow-up MRIs, 23 of 29 patients (79.3%) showed good healing, and the rest, who had persistent signs of interstitial defects on the MRIs, still had excellent outcomes. The removal of calcific deposits without repairing the cuff defects provided excellent outcomes.Cite this article: Bone Joint J 2023;105-B(6):663–667.
Low responsiveness of peripheral lymphocytes in extraparenchymal neurocysticercosis
Authors: Romo Matthew L. , Osorio Rocio , Toledo Andrea , Carrillo-Mezo Roger , Valdez Ricardo , Romano Marta C. , Sciutto Edda , Fragoso Gladis , Fleury Agnès 
Published: June 2023

Background
The morbidity and mortality of extraparenchymal neurocysticercosis (EP-NC) remain high and effectiveness of current medical treatment is suboptimal. Various factors have been implicated in the severity of EP-NC and in the poor response to treatment, but the possible role of host immune and endocrine systems has not yet been examined thoroughly.

Methodology/Principal findings
42 participants with EP-NC before receiving standard treatment and 25 healthy controls were included in the study. Treatment response was assessed by comparing pre/post treatment parasite volumes from 3D MRI. Prior to treatment among participants with EP-NC, specific stimulation induced an increased specific proliferative response accompanied by a significant increase in IL-4, NK, NKT, Bregs and Tregs cells, whereas in healthy controls, specific stimulation induced a significant increase in IL-1β, IL-5, CCL5, IL-6, TNF-α, NK and Bregs cells. Significant differences between participants with EP-NC and healthy controls in the specific inflammatory response were observed. Participants with EP-NC prior to treatment had significantly weaker responses of proinflammatory cytokines (IL-6, TNF-α) and NK cells, and stronger IL-4 response. Anthelmintic treatment did not promote significant peripheral immunological changes at any time, although inflammation was sustained in the cerebrospinal fluid. Serum estradiol concentration significantly decreased after anthelmintic treatment among males, and cortisol correlated negatively with IL-6 and positively with IFN-γ levels. No pre-treatment immunologic or endocrinologic parameters were significantly associated with response to treatment.

Conclusion/Significance
Prior to anthelmintic treatment, EP-NC was characterized by low lymphocyte reactivity accompanied by a regulatory response, which may be involved in the lack of peripheral immunological changes during and after treatment, although a central inflammatory response was present. This weak specific peripheral response could favor the chronicity of the infection and the poor response to treatment. Our findings highlight the need for new anti-inflammatory treatment focused on the central nervous system with less systemic immunosuppressive effects.
An Interpretative Phenomenological Analysis of the lived experience of sensuality expression among women over 50 years of age in Nigeria
Authors: Lawal Olubunmi Adeduntan , Duma Sinegugu Evidence 
Published: June 2023

Introduction
Sensuality, an essential component of sexuality, is the enjoyment, expression, or pursuit of physical and sexual pleasure or satisfaction. Sensuality expression of women over 50 is under-researched and often ignored, making it difficult to have a scientific basis to develop age-appropriate healthy-ageing programmes for this group in Nigeria. An exploratory study was conducted to explore the lived experiences of the expression of sensuality of Nigerian women over 50 and the meaning they attach thereto.

Methodology
An Interpretative Phenomenological Analysis approach was used to collect and analyze data from 17 female teachers from three public secondary schools in Osun state, Nigeria, to represent a homogenous group of professional women over the age of 50. A semi-structured questionnaire was used to obtain qualitative data that was thematically analyzed.

Findings
Four superordinate themes emerged: ‘Self-reinvention to camouflage ageing realities for sensuality expression’; ‘Embracing own sensuality’; ‘Yearning for old self’; and ‘Loss of interest in romantic relationships’, with various subordinate themes.

Conclusion
These finding provide the basis to develop age-appropriate healthy-ageing programmes for this group, and a baseline for further sexual health research among this group of women in Nigeria, who are often overlooked or considered asexual due to their being beyond the reproductive age.
Limitations of transcutaneous carbon dioxide monitoring in apneic oxygenation
Authors: Schweizer Thilo , Hartwich Volker , Riva Thomas , Kaiser Heiko , Theiler Lorenz , Greif Robert , Nabecker Sabine 
Published: June 2023

Background
High-flow nasal oxygenation is increasingly used during sedation procedures and general anesthesia in apneic patients. Transcutaneous CO2 (ptcCO2)-monitoring is used to monitor hypercapnia. This study investigated ptcCO2-monitoring during apneic oxygenation.

Methods
We included 100 patients scheduled for elective surgery under general anesthesia in this secondary analysis of a randomized controlled trial. Before surgery, we collected ptcCO2 measured by TCM4 and TCM5 monitors and arterial blood gas (ABG) measurements every two minutes during 15 minutes of apnea. Bland-Altman plots analyzed agreement between measurement slopes; linear mixed models estimated the different measuring method effect, and outlined differences in slope and offset between transcutaneous and arterial CO2 partial pressures.

Results
Bland-Altman plots showed a bias in slope (95% confidence intervals) between ABG and TCM4-measurements of 0.05mmHg/min (-0.05 to 0.15), and limits of agreement were -0.88mmHg/min (-1.06 to -0.70) and 0.98mmHg/min (0.81 to 1.16). Bias between ABG and TCM5 was -0.14mmHg/min (-0.23 to -0.04), and limits of agreement were -0.98mmHg/min (-1.14 to -0.83) and 0.71mmHg/min (0.55 to 0.87). A linear mixed model (predicting the CO2-values) showed an offset between arterial and transcutaneous measurements of TCM4 (-15.2mmHg, 95%CI: -16.3 to -14.2) and TCM5 (-19.1mmHg, -20.1 to -18.0). Differences between the two transcutaneous measurements were statistically significant.

Conclusions
Substantial differences were found between the two transcutaneous measurement systems, and between them and ABG. Transcutaneous CO2 monitoring cannot replace arterial CO2-monitoring during apneic oxygenation. In clinical settings with rapidly changing CO2-values, arterial blood gas measurements are needed to reliably assess the CO2-partial pressure in blood.

Assessment of critical resource gaps in pediatric injury care in Mozambique’s four largest Hospitals
Authors: Amado Vanda , Couto Maria Tereza , Filipe Manuel , Möller Jette , Wallis Lee , Laflamme Lucie 
Published: June 2023

Background
Hospitals from resource-scarce countries encounter significant barriers to the provision of injury care, particularly for children. Shortages in material and human resources are seldom documented, not least in African settings. This study analyzed pediatric injury care resources in Mozambique hospital settings.

Methods
We undertook a cross-sectional study, encompassing the country’s four largest hospitals. Data was collected in November 2020 at the pediatric emergency units. Assessment of the resources available was made with standardized WHO emergency equipment and medication checklists, and direct observation of premises and procedures. The potential impact of unavailable equipment and medications in pediatric wards was assessed considering the provisions of injury care.

Results
There were significant amounts of not available equipment and medications in all hospitals (ranging from 20% to 49%) and two central hospitals stood out in that regard. The top categories of not available equipment pertained to diagnosis and monitoring, safety for health care personnel, and airway management. Medications to treat infections and poisonings were those most frequently not available. There were several noteworthy and life-threatening shortcomings in how well the facilities were equipped for treating pediatric patients. The staff regarded lack of equipment and skills as the main obstacles to delivering quality injury care. Further, they prioritized the implementation of trauma courses and the establishment of trauma centers to strengthen pediatric injury care.

Conclusion
The country’s four largest hospitals had substantial quality-care threatening shortages due to lack of equipment and medications for pediatric injury care. All four hospitals face issues that put at risk staff safety and impede the implementation of essential care interventions for injured children. Staff wishes for better training, working environments adequately equipped and well-organized. The room for improvement is considerable, the study results may help to set priorities, to benefit better outcomes in child injuries.
Changes in Japanese physicians’ relationships with the pharmaceutical industry between 2008 and 2021: A national survey
Authors: Saito Sayaka , Mukohara Kei , Shimomura Kazuhiro , Murotani Kenta 
Published: June 2023

Background
A national survey we conducted in 2008 showed that many Japanese physicians interacted with and received gifts from pharmaceutical representatives (PRs) and had a positive attitude toward relationships with PRs. The revised promotion code of the Japan Pharmaceutical Manufacturers Association in 2019 prohibited the provision of non-educational promotional aids including sticky notes, mouse pads, and calendars. During the COVID-19 pandemic in 2020, face-to-face meetings were socially restricted. This study assessed the extent of current Japanese physicians’ involvement in pharmaceutical promotional activities and their attitudes toward relationships with PRs and to ascertain any changes between 2008 and 2021. We also examined the factors that predicted positive attitudes toward gifts from PRs.

Methods
From January to March 2021, we conducted a national mail survey of Japanese physicians in seven specialties: internal medicine, surgery, orthopedics, pediatrics, obstetrics-gynecology, psychiatry, and ophthalmology.

Results
There were 1636 participants and the response rate was 63.2%. Most physicians met face-to-face with PRs (78.8%), whereas only a minority received meals outside the workplace (4.5%). PRs were thought to have an important role in continuing medical education (66.1%) and to provide accurate information about new drugs (74.2%). Opinions were divided on the appropriateness of gifts from PRs. Most thought that stationery and meals provided by the industry did not affect prescribing behavior (89.7% and 75.8%, respectively). Factors that predicted a positive attitude toward gifts from PRs were male, orthopedic specialty vs. internal medicine, more interactions with PRs, a positive attitude toward informational value, and no rules banning meetings with PRs.

Conclusion
Involvement in pharmaceutical promotional activities is still common among practicing physicians in Japan, although the extent of the involvement had declined. Rules banning meetings with PRs appear to continue being effective at limiting a physician’s involvement with promotional activities and their critical attitudes toward gifts from PRs.

Published: June 2023

Introduction
Sarcopenia is common in men with metastatic castrate-resistant prostate cancer (mCRPC) and has been largely assessed opportunistically through computed-tomography (CT) scans, excluding measures of muscle function. Therefore, the impact of a comprehensive assessment of sarcopenia on clinical outcomes in men with mCRPC is poorly understood. The objectives of this study were to comprehensively assess sarcopenia through CT scans and measures of muscle function and examine its impact on severe treatment toxicity, time to first emergency room (ER) visit, disease progression, and overall mortality in men initiating chemotherapy or androgen receptor-targeted axis (ARAT) therapy for mCRPC.

Methods
This was a secondary analysis of a prospective observational study of men with mCRPC at the Princess Margaret Cancer Centre between July 2015-May 2021. Participants were classified as sarcopenic if they had CT-based low muscle mass or low muscle density, a grip strength and gait speed score of <35.5kg and <0.8m/s, respectively, prior to treatment initiation. The impact of sarcopenia on severe treatment toxicity was assessed using multivariable logistic regression. Multivariable Cox regression models were used to determine the impact of sarcopenia on risk of visiting the ER, prostate-specific antigen progression, radiographic progression, and overall mortality.

Results
A total of 110 men (mean age: 74.6) were included in the analysis. At baseline, 30 (27.3%) were classified as sarcopenic. Sarcopenia was a significant predictor of severe toxicity (aOR = 6.26, 95%CI = 1.17–33.58, P = 0.032) and ER visits (aHR = 4.41, 95%CI = 1.26–15.43, p = 0.020) in men initiating ARAT but not in men initiating chemotherapy. Sarcopenia was also a predictor of radiographic progression (aHR = 2.39, 95%CI = 1.06–5.36, p = 0.035) and overall mortality (aHR = 2.44, 95%CI = 1.17–5.08, p = 0.018) regardless of treatment type.

Conclusions
Baseline sarcopenia predicts radiographic progression and overall mortality in men with mCRPC regardless of the type of treatment and may also predict severe treatment toxicity and ER visits in men initiating ARAT.
Predicting vasospasm risk using first presentation aneurysmal subarachnoid hemorrhage volume: A semi-automated CT image segmentation analysis using ITK-SNAP
Authors: Street James S. , Pandit Anand S. , Toma Ahmed K. 
Published: June 2023

Purpose
Cerebral vasospasm following aneurysmal subarachnoid hemorrhage (aSAH) is a significant complication associated with poor neurological outcomes. We present a novel, semi-automated pipeline, implemented in the open-source medical imaging analysis software ITK-SNAP, to segment subarachnoid blood volume from initial CT head (CTH) scans and use this to predict future radiological vasospasm.

Methods
42 patients were admitted between February 2020 and December 2021 to our tertiary neurosciences center, and whose initial referral CTH scan was used for this retrospective cohort study. Blood load was segmented using a semi-automated random forest classifier and active contour evolution implemented in ITK-SNAP. Clinical data were extracted from electronic healthcare records in order to fit models aimed at predicting radiological vasospasm risk.

Results
Semi-automated segmentations demonstrated excellent agreement with manual, expert-derived volumes (mean Dice coefficient = 0.92). Total normalized blood volume, extracted from CTH images at first presentation, was significantly associated with greater odds of later radiological vasospasm, increasing by approximately 7% for each additional cm3 of blood (OR = 1.069, 95% CI: 1.021–1.120; p < .005). Greater blood volume was also significantly associated with vasospasm of a higher Lindegaard ratio, of longer duration, and a greater number of discrete episodes. Total blood volume predicted radiological vasospasm with a greater accuracy as compared to the modified Fisher scale (AUC = 0.86 vs 0.70), and was of independent predictive value.

Conclusion
Semi-automated methods provide a plausible pipeline for the segmentation of blood from CT head images in aSAH, and total blood volume is a robust, extendable predictor of radiological vasospasm, outperforming the modified Fisher scale. Greater subarachnoid blood volume significantly increases the odds of subsequent vasospasm, its time course and its severity.
Risk perception of non-communicable diseases: A systematic review on its assessment and associated factors
Authors: Jane Ling Miaw Yn , Ahmad Norfazilah , Aizuddin Azimatun Noor 
Published: June 2023

Background
The burden of non-communicable diseases (NCDs) is increasing. Risk perception of NCDs is an important factor towards the uptake of preventive health interventions. There are various questionnaires assessing risk perception of NCDs, but no internationally standardized questionnaire has been available. Identification of factors associated with risk perception of NCDs may facilitate the development of targeted interventions. This systematic review aims to identify available questionnaire assessing risk perception of NCDs and the factors associated with risk perception of NCDs.

Methods
The reporting of this systematic review is in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We carried out a literature search through three databases (Scopus, PubMed, Web of Science) and targeted original article published in English between 2012 and 2021. Quality appraisal of the eligible articles was conducted using the Mixed Methods Appraisal Tool. Findings were synthesized using content analysis.

Results
A total of 86 studies were included. We found a variety of questionnaires assessing risk perception of NCDs, with many differences in their development, domains, items and validity. We also identified several personal, sociopsychological and structural factors associated with risk perception of NCDs.

Limitations
Most of the included studies were of cross-sectional design, and therefore the quality of evidence was considered low and exhibit a high risk of bias. The role of publication bias within this systematic review should be acknowledged as we did not include grey literature. Additionally, language bias must be considered as we only included English-language publications.

Conclusion
Further development and testing of available questionnaire is warranted to ensure their robustness and validity in measuring risk perception of NCDs. All the identified factors deserve further exploration in longitudinal and experimental studies.
