Factors associated with increased radiation exposure in the fixation of proximal femoral fractures

Ann R Coll Surg Engl. 2024 Apr 2. doi: 10.1308/rcsann.2023.0092. Online ahead of print.

ABSTRACT

INTRODUCTION: When using radiation intraoperatively, a surgeon should aim to keep the radiation dose as low as is reasonably achievable to obtain the therapeutic goal. We aimed to investigate factors associated with increased radiation exposure in fixation of proximal femur fractures.

METHODS: We assessed 369 neck of femur fractures over a 1-year period in a district general hospital. All hip fracture subtypes that had undergone surgical fixation were included. We assessed the relationship between type of fracture, implants used and surgeon level of experience with the dose-area product (DAP; cGy/cm2) and screening time (dS). We also looked at the quality of reduction and fixation and its effect on the radiation exposure.

RESULTS: A total of 184 patients were included in our analysis; 185 patients who were treated with hip arthroplasty were excluded. There was a significant association between higher DAP and fracture subtype (p = 0.001), fracture complexity (p < 0.001), if an additional implant was used (p = 0.001), if fixation was satisfactory (p = 0.002) and operative time (p < 0.001). DAP was higher with a proximal femoral nail than with a dynamic hip screw, especially when a long nail was used. There was some evidence of an association between the surgeon’s level of experience and DAP exposure, although this was not statistically significant (p = 0.069).

CONCLUSIONS: Increased radiation in proximal femur fractures is seen in the fixation of complex fractures, some subtypes, with certain types of implants used and if an additional implant was required. Surgeon seniority did not result in less radiation exposure, which is in contrast to other published studies.

Association of day-case rates with post COVID-19 recovery of elective laparoscopic cholecystectomy activity across England

Ann R Coll Surg Engl. 2024 Apr 2. doi: 10.1308/rcsann.2023.0111. Online ahead of print.

ABSTRACT

INTRODUCTION: The aim of this study was to investigate the safety of day-case laparoscopic cholecystectomy, and the association between day-case rates and, post the COVID-19 pandemic, recovery of activity to prepandemic levels for integrated care boards (ICBs) in England.

METHODS: This was a retrospective observational study of the Hospital Episodes Statistics (HES) data set. Elective laparoscopic cholecystectomies for the period 1 January 2019 to 31 December 2022 were identified. Activity levels for 2022 were compared with those for the whole of 2019 (baseline). Day-case activity was identified where the length of stay recorded in the HES was zero days.

RESULTS: Data were available for 184,252 patients across the 42 ICBs in England, of which 120,408 (65.3%) were day-case procedures. By December 2022, activity levels for the whole of England had returned to 88.2% of prepandemic levels. The South West region stood out as having recovered activity levels to the greatest extent, with activity at 97.3% of prepandemic levels during 2022. The South West also had the highest postpandemic day-case rate at 74.9% of all patients seen as a day-case during 2022; this compares with an England average of 65.3%. At an ICB level, there was a significant correlation between day-case rates and postpandemic activity levels (r = 0.362, p = 0.019). There was no strong or consistent evidence that day-case surgery had poorer patient outcomes than inpatient surgery.

CONCLUSIONS: Recovery of elective laparoscopic cholecystectomy activity has been better in South West England than in other regions. Increasing day-case rates may be important if ICBs in other regions are to increase activity levels up to and beyond prepandemic levels.

Developing an intelligent prediction system for successful aging based on artificial neural networks

Int J Prev Med. 2024 Feb 29;15:10. doi: 10.4103/ijpvm.ijpvm_47_23. eCollection 2024.

ABSTRACT

BACKGROUND: Due to the growing number of disabilities in elderly, Attention to this period of life is essential to be considered. Few studies focused on the physical, mental, disabilities, and disorders affecting the quality of life in elderly people. SA1 is related to various factors influencing the elderly’s life. So, the objective of the current study is to build an intelligent system for SA prediction through ANN2 algorithms to investigate better all factors affecting the elderly life and promote them.

METHODS: This study was performed on 1156 SA and non-SA cases. We applied statistical feature reduction method to obtain the best factors predicting the SA. Two models of ANNs with 5, 10, 15, and 20 neurons in hidden layers were used for model construction. Finally, the best ANN configuration was obtained for predicting the SA using sensitivity, specificity, accuracy, and cross-entropy loss function.

RESULTS: The study showed that 25 factors correlated with SA at the statistical level of P < 0.05. Assessing all ANN structures resulted in FF-BP3 algorithm having the configuration of 25-15-1 with accuracy-train of 0.92, accuracy-test of 0.86, and accuracy-validation of 0.87 gaining the best performance over other ANN algorithms.

CONCLUSIONS: Developing the CDSS for predicting SA has crucial role to effectively inform geriatrics and health care policymakers decision making.

Differences in the Impact of Various Types of Exercise on Irisin Levels: A Systematic Review and Meta-Analysis

Int J Prev Med. 2024 Feb 29;15:11. doi: 10.4103/ijpvm.ijpvm_76_23. eCollection 2024.

ABSTRACT

BACKGROUND: Irisin, a myokine that is responsive to exercise, induces significant changes in subcutaneous adipose tissue. By promoting the browning of white fat tissue, it enhances energy expenditure, thereby addressing overweight and obesity. This systematic review and meta-analysis aimed to compare the effects of different types of physical exercises on irisin levels in overweight and obese adults.

METHODS: Specifically, the review focused on studies involving obese or overweight individuals who participated in exercise training for a minimum of 8 weeks, with measured and reported changes in serum irisin levels compared to a control group. Data were collected from four databases (Google Scholar, ISI Web of Science Core Collection, PubMed, and Scopus). The risk of bias was assessed using the Begg and Egger tests, and the results were synthesized.

RESULTS: Initial searches identified 560 titles, out of which only seven met the criteria for inclusion in the systematic review. Statistical analysis demonstrated a significant increase in serum irisin concentration (SMD = 0.957, P = 0.005) among obese and overweight individuals who engaged in exercise, compared to the passive control group. High-intensity interval training (HIIT) (SMD = 1.229, P < 0.001) had a more pronounced effect on increasing serum irisin levels than other exercise protocols. Furthermore, the effectiveness of exercise varied based on the participants’ weight status (significant changes for overweight individuals; P < 0.001 and insignificant changes for obese individuals; P = 0.1), age (significant changes for those under 40 years old; P < 0.001 and insignificant changes for those over 40 years old; P = 0.322), and gender (significant changes for men; P < 0.001 and insignificant changes for women; P = 0.285).

CONCLUSIONS: Consequently, exercise can elevate serum irisin levels, leading to alterations in adipose tissue phenotype and thermogenesis, ultimately contributing to weight reduction in obese and overweight individuals.

Patterns of help-seeking behavior among people with mental illness in Ethiopia: a systematic review and meta-analysis

Front Psychiatry. 2024 Mar 18;15:1361092. doi: 10.3389/fpsyt.2024.1361092. eCollection 2024.

ABSTRACT

BACKGROUND: Despite the availability of evidence-based and effective treatments, significant numbers of people living with mental illness do not receive treatment or do not seek help from providers of formal modern treatment. Although numerous primary studies have been conducted on patterns of help-seeking behavior among individuals with mental illness with respect to modern therapy, the evidence has not been aggregated nationwide. Therefore, the aim of this review was to investigate pooled data on patterns of help-seeking behavior among individuals with mental illness in Ethiopia.

METHODS: All available primary studies were searched via the Google Scholar, HINARI, and PubMed databases from June 22 to December 20, 2023; 912 articles were identified. Sixteen articles were included in the final review; data from them were extracted to an Excel spreadsheet and exported to Stata version 17 for analysis. The search terms used were: “Pattern of help-seeking behavior” OR “Pattern of treatment-seeking behavior” OR “Health care-seeking behavior” OR “Help-seeking intention” OR “Help-seeking preferences” OR “Perceived need” OR “Pathways to psychiatric care”, AND “Common mental disorders” OR “Mental illness” OR “Mental health problems” OR “Depression”, AND “Predictors” OR “Determinate factors” OR “Associated factors”, AND “Ethiopia”. The quality of the studies included was critically appraised using the modified The Joanna Briggs Institute (JBI) Joanna Briggs Institute quality assessment tool, adapted for observational studies. During critical appraisal, disagreements between the two authors conducting the assessment were resolved by the involvement of a third author. Effect sizes were pooled using the random effects model, and the presence of publication bias was detected based on asymmetry of the funnel plot and a statistically significant result of Egger’s test (p<0.05).

RESULTS: The pooled rate of positive help-seeking behavior with respect to modern treatment among people living with mental illness was 42.21% (95% CI: 29.29, 55.12; I2 = 99.37%, P=0.00). Factors significantly associated with a positive pattern of help-seeking behavior were: having a secondary education or above (AOR=5.47, 95% CI: 2.33, 12.86); believing that mental illness requires treatment (AOR=2.76, 95% CI: 2.02, 3.78); having strong social support (AOR=2.00, 95% CI: 1.64, 2.44); having a family history of mental illness (AOR=2.68, 95% CI: 1.38, 3.97); having awareness of the availability of treatment (AOR=2.92, 95% CI: 1.56, 5.46); having previously engaged in positive help-seeking behavior (AOR=3.28, 95% CI: 1.63, 6.60); having comorbid disorders (AOR=4.25, 95% CI: 1.69, 10.66); not using alcohol (AOR=3.29, 95% CI: 1.73, 6.27); and the perceived severity of mental illness (AOR=2.54, 95% CI: 1.490, 4.33).

CONCLUSIONS: The majority of people with mental illness in Ethiopia exhibited a poor pattern of help-seeking behavior with respect to modern treatment. Therefore, mobilization of the community should be encouraged via regular public awareness campaigns regarding mental illness and the availability of evidence-based and effective modern treatment in Ethiopia. Moreover, the design of effective community-based mental health interventions is recommended in order to improve public attitudes and rates of help-seeking behavior in relation to mental health problems.

Brain function abnormalities and neuroinflammation in people living with HIV-associated anxiety disorders

Front Psychiatry. 2024 Mar 18;15:1336233. doi: 10.3389/fpsyt.2024.1336233. eCollection 2024.

ABSTRACT

BACKGROUND: People living with HIV (PLWH) exhibits an increased susceptibility to anxiety disorders, concomitant with heightened vulnerability to aberrant immune activation and inflammatory responses, and endocrine dysfunction. There exists a dearth of scholarly investigations pertaining to the neurological, immune, and endocrine dimensions of HIV-associated anxiety disorders.

METHOD: This study aimed to compare a group of 16 individuals diagnosed with HIV-associated anxiety disorders (HIV ANXs) according to the Diagnostic and statistical manual of mental disorders (5th ed.), with a HIV individual control group (HIV control) of 49 PLWH without mental disorders. Muti-modal magnetic resonance was employed to assess the brain function and structure of both groups. Seed-based functional connectivity (FC) was used to assess the regional intrinsic brain activity and the influence of regional disturbances on FC with other brain regions. Peripheral blood cytokines and chemokines concentrations were measured using liquid chip and ELISA.

RESULTS: Amplitude of low-frequency fluctuations in the right inferior temporal gyrus (ITG) was increased. There is a significant decreased regional homogeneity in HIV ANXs in the right superior occipital gyrus (SOG). The right ITG and the right SOG were separately set as the seed brain region of interest (ROI 1 and ROI 2) to be analyzed the FC. FC decreased in HIV ANXs between ROI1 and the right middle occipital gyrus, the right SOG, FC between ROI2 and left ITG increased in HIV ANXs. No significant structural difference was found between two groups. Pro-inflammatory chemokines showed higher levels in the HIV ANXs. Pro-inflammatory cytokines, neurotrophic factors, and endocrine factors were significantly correlated with alterations in brain function.

CONCLUSION: This study suggests that patients with HIV-associated anxiety disorders may exhibit abnormalities in neurologic, immune, and endocrine functioning. Consequently, it is imperative to implement additional screening and intervention measures for anxiety disorders among PLWH.

Multicultural personality traits of Chinese university students and their effects on the psychological adjustment in the aftermath of COVID-19 in Shanghai: a scale validation

Front Psychiatry. 2024 Mar 11;15:1363809. doi: 10.3389/fpsyt.2024.1363809. eCollection 2024.

ABSTRACT

OBJECTIVE: This study aims to explore Chinese university students’ multicultural personalities and examine how they predict the psychological adjustment of students in Shanghai. In addition, the validation of Multicultural Personality Questionnaire Short Form (MPQ-SF) scale developed to assess the multicultural personality traits of individuals is also aimed in Chinese context. Data were collected after the psychological stresses from restrictions imposed by COVID-19 in China that influenced life adjustments for nearly three years.

METHOD: A total of 1,099 university students participated in this multi-stage study. First, the Chinese version of MPQ-SF (MPQ-SF-C) was developed and validated. The impact of MPQ-SF-C dimensions was then tested through path analysis to establish the effects of Chinese university students’ multicultural personality traits on their psychological adjustment using the Schwartz Outcome Scale (SOS-10).

RESULTS: The MPQ-SF-C yielded a five-factor solution which accounted for 60.14% of the common variance. The findings indicated that cultural empathy (β = 0.23, p < 0.05), certainty seeking (β = 0.13, p < 0.05), open-mindedness (β = 0.48, p < 0.05), and emotional stability (β = 0.24, p < 0.05) had significant influences on adjustment. Only flexibility was found to have a statistically insignificant impact on adjustment at this time in this context. MPQ-SF-C and SOS-10 scales represented very good psychometric properties in terms of their reliability and validity.

CONCLUSION: The MPQ-SF-C shows good psychometric properties and appropriateness for evaluating multicultural personalities in Chinese contexts. The multicultural personality characteristics of university students using this scale well predicted their psychological adjustment.

Attitude towards healthy nutrition and mental toughness: a study of taekwondo athletes

PeerJ. 2024 Mar 29;12:e17174. doi: 10.7717/peerj.17174. eCollection 2024.

ABSTRACT

Healthy nutrition is widely considered the cornerstone of optimal athletic performance, both physically and mentally. This study investigates the critical role of healthy nutrition in shaping the physical and mental performance of athletes, with a specific focus on taekwondo. This research aims to explore the potential relationship between taekwondo athletes’ attitudes towards healthy nutrition and their mental toughness. The research group comprised 276 active and licensed taekwondo athletes who voluntarily participated in the study (Age M = 17.18 ± SD = 7.13, N = 125 women, N = 151 men). Ethical approval for the research was obtained prior to the commencement of the study. Data collection instruments included the Healthy Nutrition Attitude Scale, Mental Toughness Scale, and a personal information form. Confirmatory factor analysis was conducted to confirm the validity and reliability of the scales. Descriptive statistics, correlation analysis, and regression analysis were performed to explore the relationship between the variables within the research model. The correlation analysis identified two significant, positive, and moderate correlations: (1) between knowledge about nutrition and mental toughness (r = 0.626) and (2) between positive nutrition and mental toughness (r = 0.672). The regression analysis revealed that both knowledge about nutrition (β = 0.360) and positive nutrition (β = 0.461) significantly contribute to mental toughness. The findings suggest that as athletes’ knowledge of nutrition expands and their attitudes towards healthy eating become more positive, their mental toughness also appears to improve. These results are both important and original, adding significant new insights to the existing research landscape.

The relationship between appearance anxiety and depression among students in a medical university in China: a serial multiple mediation model

PeerJ. 2024 Mar 29;12:e17090. doi: 10.7717/peerj.17090. eCollection 2024.

ABSTRACT

BACKGROUND: Appearance anxiety and depression have become common and global public health problems worldwide, especially among adolescents. However, few studies have revealed the mechanisms between them. This study aimed to explore the multiple mediating roles of interpersonal sensitivity and social support between appearance anxiety and depression among medical college students.

METHODS: With 13 invalid samples excluded, 724 college students participated in our survey and completed questionnaires. The average age of 724 samples was 19.8 ± 2.02 including freshman to senior year and graduate school and above; 31.9% of the participants were male and 68.1% were female. SPSS 25.0 and Hayes’ PROCESS macro were used for statistical description, correlation analysis and built multiple mediation models.

RESULTS: Appearance anxiety can not only directly affect depression, but also indirectly affect depression through three significant mediating pathways: (1) IS (B = 0.106, 95% CI [0.082-0.132]), which accounted for 49.77% of the total effect, (2) SS (B = 0.018, 95% CI [0.008-0.031]), which accounted for 8.45% of the total effect, and (3) IS and SS (B = 0.008, 95% CI [0.003-0.014]), which accounted for 3.76% of the total effect. And the total mediating effect was 61.97%.

LIMITATIONS: It is a cross-sectional research method and the causal relationship is unclear.

CONCLUSIONS: This study found that lower interpersonal sensitivity and higher social support can effectively reduce depression caused by appearance anxiety among college students. The schools and relevant departments should take measures to reduce the interpersonal sensitivity of college students and establish reliable social support, so as to reduce the occurrence of depression.

Preoperative Nil Per Os Duration Predicts Mortality and Ambulation Following Below-Knee Amputation

Am Surg. 2024 Apr 1:31348241244633. doi: 10.1177/00031348241244633. Online ahead of print.

ABSTRACT

BACKGROUND: Routine use of nil per os (NPO) prior to procedures has been associated with dehydration and malnutrition leading to patient discomfort. We aim to examine how duration of NPO status affects postoperative outcomes in patients undergoing elective below-knee amputation (BKA).

METHODS: We performed a retrospective chart review of 92 patients who underwent elective BKA between 2014-2022 for noninfectious indications. We performed statistical analysis using Chi-square tests, t-tests, and linear/logistic regression with odds ratio using P < .05 as our significance level.

RESULTS: The mean age was 48.0 ± 16.7 years, and there were 64 (70%) male patients and 41 (45%) Black patients. Mean NPO duration was 12.9 ± 4.7 hours. Patients with longer NPO duration were associated with increased rates of postoperative stroke (P = .03). Patients with shorter NPO duration had significantly lower mean BUN on postoperative day (POD) 1 (14.5, P < .001) and POD 3 (14.1, P < .001) compared to preoperative mean BUN (16.8), however this normalized by POD 7 (19.2, P = .26). There were no changes in postoperative renal function based on baseline kidney disease status or associated with longer NPO duration. Shorter NPO duration was a predictor of increased likelihood of 1-year follow-up (OR: 2.9 [1.24-6.79], P = .01), independent ambulation (OR: 2.7 [1.03-7.34], P = .04), and decreased mortality (OR: .11 [.013-.91], P = .04).

CONCLUSION: While NPO duration does not appear to result in postoperative renal dysfunction, prolonged NPO duration predicts worse rates of follow-up, ambulation, and survival and is associated with increased stroke rates.
