Geographic variation in the association between Hashimoto's thyroiditis and Papillary thyroid carcinoma, a meta-analysis

PURPOSE

The association between papillary thyroid cancer (PTC) and Hashimoto's thyroiditis (HT) remains a matter of debate. Several genetic and environmental factors have been found to influence this association. Because of the variation in these factors among different populations, we conducted a country- and region-based meta-analysis to examine whether the geographic area influences this association.

METHODS

We searched PubMed and Web of Science databases for original articles that investigated the association between HT and PTC from February 1955 to February 28, 2023. The included studies were stratified according to their country and region of origin. Various subgroup analyses were conducted. The primary outcome was the pooled relative risk (RR) and its 95% confidence interval (CI) for each region and country.

RESULTS

Forty-six studies including a total of 93,970 participants met our inclusion criteria. They originated from 16 countries distributed in five regions. Significant variation was found among countries but not among regions. Upon analysis of all 46 included studies, countries were classified based on their RR and its 95% CI. Excluding countries with pooled sample sizes <500, Sri Lanka (RR 4.23, 95% CI 2.91-6.14), Poland (RR 3.16, 95% CI 2.79-3.57) and Japan (2.68, 2.14-3.36) showed the strongest association between HT and PTC while Greece (RR 1.06, 95% CI 1.00-1.13), Spain (RR 0.70, 95% CI 0.23-2.11), and Jordan (0.62, 0.32-1.32) showed no significant association.

CONCLUSION

Our findings revealed a variation in the association between HT and PTC among countries but not among regions. The country-to-country variation could be due to certain genetic and/or environmental factors subject to geographic variation that influence this association. These findings may help guide health policies aiming to mitigate the risk of PTC in the HT population by helping identify high-risk and low-risk countries.

Single-Center Retrospective Analysis of Neutrophil, Monocyte, and Platelet to Lymphocyte Ratios as Predictors of Complicated Appendicitis

Aim

We look at the ability of the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and monocyte-to-lymphocyte ratio (MLR) to differentiate between uncomplicated and complicated appendicitis.

Methods and materials

This was a retrospective, single-center study of 234 individuals diagnosed with acute appendicitis between January 1, 2020, and December 31, 2020. Patients were grouped into uncomplicated and complicated appendicitis subgroups. Patients with histologically or radiologically proven gangrenous or perforated appendicitis, as well as those with peritonitis or peri-appendiceal abscess development, comprise the complicated subgroup. Independent Mann-Whitney samples The U test was used to predict lab values of complicated appendicitis. Furthermore, the receiver operating characteristic (ROC) curve and area under the curve (AUC) were utilized to predict the sensitivity and specificity of laboratory results reported to have a significant connection with complex appendicitis

Results

The criteria were met by 186 patients, with a male-to-female proportion of 1.06:1, an average age of 36.4 years, and an average stay of 2.73 days. There were 95 individuals with complicated appendicitis. With 66.3%, perforated appendicitis was the most prevalent condition. The ratios of neutrophils to lymphocytes, monocytes to lymphocytes, and platelets to lymphocytes were linked with complicated appendicitis with a p-value of < 0.0001, and p-values = 0.015, and 0.015, respectively.

Conclusion

NLR, MLR, and PLR are valid, less onerous surrogate biomarkers for measuring the severity of acute complicated appendicitis and differentiating it from uncomplicated appendicitis.

Bilirubin as a Predictor of Complicated Appendicitis in a District General Hospital: A Retrospective Analysis

Aims

The objectives of the study were to establish the function of bilirubin as a novel diagnostic tool for predicting complex appendicitis and to compare the impact of other variables such as white blood cell count (WCC), C-reactive protein (CRP), and neutrophil.

Methods

This retrospective, single-center cohort analysis included all patients admitted to Torbay General Hospital in Torquay, United Kingdom, between January 2020 and December 2020 with a clinical diagnosis of acute appendicitis. In addition to serum CRP, WCC, and neutrophil, serum bilirubin and other liver enzymes were obtained from the patients’ blood on admission.

Results

The quantitative analysis included 174 patients from the group that remained. The large majority of the sample consisted of adults and males (77% and 51.7%, respectively). Overall, 49.4% of participants in the study were diagnosed with complicated appendicitis; 74.7% of adults had complicated appendicitis, with 58.6% being male. In 68.6% of cases, perforated appendicitis was the most prevalent form of complicated appendicitis. Patients with complicated appendicitis had significantly higher WCC, neutrophil, and CRP levels than those with uncomplicated appendicitis (14.15 vs. 12.88, p = 0.016; 11.63 vs. 10.19, p = 0.007; and (89.28 vs. 40.65, p = 0.0001, respectively).. The significantly greater alkaline phosphatase and total serum bilirubin discrepancies were observed in patients with complicated appendicitis. There were statistically significant differences in the means of the patients: (18.46 vs. 10.98, p = 0.0001 and 110.64 vs. 102.24, p = 0.033).

Conclusion

Serum bilirubin is a crucial diagnostic aid for determining the existence of complicated appendicitis.

Gender-based disparities on health indices during COVID-19 crisis: a nationwide cross-sectional study in Jordan

Background

COVID-19 has an inevitable burden on public health, potentially widening the gender gap in healthcare and the economy. We aimed to assess gender-based desparities during COVID-19 in Jordan in terms of health indices, mental well-being and economic burden.

Methods

A nationally representative sample of 1300 participants ≥18 years living in Jordan were selected using stratified random sampling. Data were collected via telephone interviews in this cross-sectional study. Chi-square was used to test age and gender differences according to demographics, economic burden, and health indices (access to healthcare, health insurance, antenatal and reproductive services). A multivariable logistic regression analysis was used to estimate the beta-coefficient (β) and 95% confidence interval (CI) of factors correlated with mental well-being, assessed by patients’ health questionnaire 4 (PHQ-4).

Results

656 (50.5%) men and 644 (49.5%) women completed the interview. Three-fourths of the participants had health insurance during the COVID-19 crisis. There was no significant difference in healthcare coverage or access between women and men (p > 0.05). Half of pregnant women were unable to access antenatal care. Gender was a significant predictor of higher PHQ-4 scores (women vs. men: β: 0.88, 95% CI: 0.54–1.22). Among women, age ≥ 60 years and being married were associated with significantly lower PHQ-4 scores. Only 0.38% of the overall participants lost their jobs; however, 8.3% reported a reduced payment. More women (13.89%) were not paid during the crisis as compared with men (6.92%) (P = 0.01).

Conclusions

Our results showed no gender differences in healthcare coverage or access during the COVID-19 crisis generally. Women in Jordan are experiencing worse outcomes in terms of mental well-being and economic burden. Policymakers should give priority to women’s mental health and antenatal and reproductive services. Financial security should be addressed in all Jordanian COVID-19 national plans because the crisis appears widening the gender gap in the economy.

Burnout Syndrome during Residency Training in Jordan: Prevalence, Risk Factors, and Implications

Burnout syndrome is common among healthcare professions, including resident physicians. We aimed to assess the prevalence of burnout among resident physicians in Jordan, and a secondary aim was to evaluate the risk factors associated with the development of burnout syndrome in those residents, including gender, working hours, psychological distress, training sector, and specialty. In this cross-sectional study, 481 residents were recruited utilizing multistage stratified sampling to represent the four major health sectors in Jordan. Data were collected using an online questionnaire, where the Copenhagen Burnout Inventory (CBI) was used to assess the prevalence of burnout. The prevalence, group differences, and predictors of burnout were statistically analyzed using STATA 15. Overall, 373 (77.5%) residents were found to have burnout. Factors associated with higher levels of burnout were psychological stress (β = 2.34, CI = [1.88-2.81]), longer working hours (β = 4.07, CI = [0.52-7.62], for 51-75 h a week, β = 7.27, CI = [2.86-11.69], for 76-100 h a week and β = 7.27, CI = [0.06-14.49], for >100 h a week), and obstetrics/gynecology residents (β = 9.66, CI = [3.59-15.73]). Conversely, medical sub-specialty residents, as well as private and university hospital residents, had lower burnout levels. We concluded that decreasing the workload on residents, offering psychological counseling, and promoting a safety culture for residents might help in mitigating burnout consequences.

Role of Arthrodiastasis Using Hinged Monolateral External Fixator Without Soft Tissue Release in Advanced Stage of Legg-Calve-Perthes Disease

Purpose

Presentation with the advanced stage of Legg-Calve-Perthes disease (LCPD) carries a poor prognosis, regardless of the treatment that the patient receives. The aims of this study are to assess the clinical and radiological outcomes of arthrodiastasis in advanced cases of LCPD using a hinged monolateral external fixator without soft tissue release and to raise safety issues regarding its low rate of complications.

Patients and Methods

Six patients with LCPD who were classified as lateral pillar types B and C and were operated on in our department were included in this retrospective study. Data collected from medical files and X-ray measurements were retrospectively reviewed.

Results

A total of six male patients were included in this analysis. The mean age at onset of symptoms was 8.5 years (range 7-10 years). The mean follow-up period was 46 months (range 40-50 months). Five cases were Herring C and one case was Herring B at presentation. The average distraction time was 8 days (range 7-9) and the average duration of external fixator application was 3.1 months (range 2.5-3.5 months). The range of motion of the hip in flexion, abduction and internal rotation were improved postoperatively. Pain score and limping were also improved. At the final follow-up, the mean sphericity deviation score was 10.6. The mean epiphyseal index was improved from 19.3% to 23.8%. In addition, the mean cervical index improved from 99.7% to 89.7% at the last follow-up. Femoral fractures, pin loosening, mechanical failure of the fixator, chondrodiastasis, and hip subluxation were not seen in this group of patients.

Conclusion

Arthrodiastasis with a hinged monolateral external fixator without soft tissue release improved both the clinical and radiological outcomes in this group of patients.

Budd-Chiari syndrome associated with factor V leiden mutation: a report of 6 patients

Budd-Chiari syndrome is characterized by hepatic venous outflow obstruction. Although myeloproliferative disorders are usually responsible for this severe thrombotic disorder, deficiency or dysfunction of the natural anticoagulants can be involved. Resistance to activated protein C caused by factor V Leiden mutation has been recently identified as a major cause of thrombophilia. We report 6 patients with Budd-Chiari syndrome associated with factor V Leiden mutation combined with another acquired thrombophilic state (myeloproliferative disorder and lupus anticoagulant in 3 cases) and without another thrombophilic disorder in the other 3 cases. We conclude that factor V Leiden mutation should be evaluated in any case of hepatic vein occlusion because the prevalence of this mutation in the general population is high.
