Epidemiology of Cancers in Vidarbha Over 4-year Period, Tobacco-related Cancer and Control

Objectives: The aim of the study was to describe epidemiology of cancer in Vidarbha, according to findings from National Cancer Registry Programme (NCRP). Material and Methods: The data on cancer have been sourced from Hospital Based Cancer Registries of Rashtrasant Tukdoji Cancer Hospital and Research Centre under NCRP in Vidarbha. The data are covering a period of 4 years (2017–2020). Results: The Hospital-based cancer Registry of Rashtrasant Tukdoji Cancer Hospital and Research Center indicates 11,868 malignant cases registered in the hospital during the period of past years (2017–2020). The top 5 leading sites in males were buccal mucosa, tongue, lung, alveolus and oesophagus. In females, top 5 leading sites are buccal mucosa, tongue, oesophagus, lung and alveolus. The Rashtrasant Tukdoji Cancer Hospital data of cumulative distribution of cancer cases according to age and gender which cancer was found to be more in males than females and increased incidence in younger ages is observed in the study. Conclusion: Epidemiological studies help in assessing cancers and help to assess their risk factors and help in improving and strengthening efforts for cancer prevention and control. Epidemiological studies show that many cancer can be avoidable with primary and secondary preventive measures and also helps in estimating the cancer burden in the near future and helps in planning and evaluating strategies by keeping track of cancer prevalence. Cancer registry plays an important role in such studies.

Incidence and Clinical Course of Femoral Localized Periosteal Thickening and Atypical Femoral Fracture over a 10-year Period in Patients with Autoimmune Inflammatory Rheumatic Disease

Abstract Atypical femoral fracture (AFF) is generally a rare complication of long-term use of bisphosphonate (BP); glucocorticoid (GC) use and Asian race are also risk factors. Femoral localized periosteal thickening (LPT, also termed “beaking”) of the lateral cortex often precedes AFF. This cohort study investigated the incidence of LPT and AFF and their clinical courses over 10 years in patients with autoimmune inflammatory rheumatic diseases (AIRDs) treated with BP and GC. The study population consisted of 121 patients with AIRDs taking BP and GC. LPT was screened by X-ray, and the LPT shape was evaluated. Prednisolone (PSL) dose was 10 (8–12) mg/day at enrollment and 9 (6–10) mg/day at the last observation. LPT was evident in 10 patients at enrollment and increased linearly to 31 patients (26%) at the last observation. AFF occurred in nine femurs of five patients with LPT. All patients with AFF had bilateral LPT, and the prevalence of pointed type and LPT height were higher in the AFF-positive group than in the AFF-negative group. AFF occurred before BP discontinuation in two patients, 1 year after BP discontinuation in one, after BP discontinuation followed by 7 years of alfacalcidol use in one, and after switching from alfacalcidol to denosumab in one. The prevalence rates of AFF and LPT associated with long-term BP use with concomitant use of GC (mostly PSL ≥ 6 mg/day) in Japanese patients with AIRD increased over time. The selection of long-term osteoporosis treatment for LPT-positive patients is difficult in some cases.

Myopia trends among children and adolescents: a nationwide study in South Korea

PurposeTo evaluate gender disparities in the progression of myopia among children and adolescents in South Korea. MethodsNationwide cross-sectional data of 1,190 subjects aged 10-18 years was obtained for the years of 2011 (baseline) and 2021 using the Korea National Health and Nutrition Examination Surveys. The prevalence of myopia, as well as data regarding age, household income, height, weight, body mass index, and age of menarche, were evaluated. Myopia was defined as a spherical equivalent (SE) ≤ −0.5 D. ResultsThe prevalence of myopia among boys was stable in2021 compared to 2011, with rates of 53.7% and 52.8%, respectively (P = 0.372). Among girls, however, there was a statistically significant increase in myopia prevalence in 2021 compared to 2011, with rates of 73.7% and 51.6% (P < 0.001), respectively. Over 10 years, the adjusted prevalence ratio for myopia in boys was 1.11 (95% CI, 0.77-1.61), whereas myopia prevalence in girls underwent a 1.87-fold increase over the same period (95% CI, 1.30-2.69), and menarche at <12 years of age was associated with myopia in girls (PR = 0.84; 95% CI, 0.72-0.99). The spherical equivalent refraction in girls increased significantly over the same 10-year period, from −1.09 ± 0.13 D to −1.58 ± 0.17 D (P < 0.017), whereas in boys, there was no significant difference (P = 0.604). ConclusionsIn our study cohort, the prevalence of myopia increased significantly among girls compared with boys over the course of decade. Additionally, an association between early menarche in girls and the prevalence of myopia was observed.

Physical Fitness as a Predictor of Disability Retirement: A 9-Year Register Linked Follow-Up Study.

To prospectively examine the association between physical fitness and risk of disability retirement in a large population-based cohort. This study utilized data from Health 2011 survey Physical Activity subsample (n = 4898), combined with information on disability retirement derived from 2 national registers. In total, 2455 individuals aged 18-74years underwent the physical fitness test protocol concerning measures of cardiorespiratory fitness, muscle strength, and balance. The outcome variable was disability retirement, during the follow-up period of 9years. After excluding those not at risk of disability retirement (ie, age ≥63 y) or who had already been granted disability pension, and those who had not completed the fitness protocol, the analytical sample included 1381 participants. Data were analyzed using Cox regression model with SPSS (version 29). During the 9-year follow-up period, 61 individuals (4.4%) transitioned to a disability retirement. Cox regression analysis showed an association between the various physical fitness subdomains and the risk of disability retirement. In model 1, all fitness tests were associated with the risk of disability retirement, except the one-leg stand test with hazard ratios ranging from 1.69 (95% CI, 0.86-3.34) to 5.75 (95% CI, 1.84-17.90). Further adjustment for sociodemographic, health behavior, and health-related covariates attenuated the associations and statistical significance was lost, except for the vertical jump test (hazard ratio = 4.33; 95% CI, 1.32-14.10) and 6-minute walk test (hazard ratio = 3.81; 95% CI, 1.35-10.70). These findings highlight the importance of physical fitness for preventing work disability.

Long-Term Results of 2-Stage Turnbull-Cutait Pull-Through Coloanal Anastomosis for Low Rectal Cancer

In patients operated on for low rectal cancer, 2-stage Turnbull-Cutait pull-through hand-sewn coloanal anastomosis provides benefits in terms of postoperative morbidity compared with standard hand-sewn coloanal anastomosis associated with diverting ileostomy and further ileostomy reversal. To compare long-term results of these 2 techniques after ultralow rectal resection for rectal cancer. In this randomized multicenter clinical trial, neither patients nor surgeons were blinded for technique. Patients were recruited in 3 centers. Patients undergoing ultralow anterior rectal resection needing hand-sewn coloanal anastomosis were randomly assigned to 2-stage Turnbull-Cutait pull-through hand-sewn coloanal anastomosis (n = 46) or standard hand-sewn coloanal anastomosis associated with diverting ileostomy (n = 46). All patients underwent ultralow anterior resection. Patients assigned to the 2-stage Turnbull-Cutait pull-through group underwent exteriorization of a segment of left colon through the anal canal. After 6 to 10 days, the exteriorized colon was resected and a delayed hand-sewn coloanal anastomosis performed. For patients assigned to standard coloanal anastomosis, the hand-sewn coloanal anastomosis was performed with diverting ileostomy during the first operation. Ileostomy closure was scheduled after adjuvant treatment was completed in about 6 to 8 months. The study aimed to compare the differences between the 2 groups in terms of long-term surgery-related morbidity, functional, and oncological outcomes at 3 years postoperatively. Data were analyzed from October 1, 2018, through October 31, 2021. The 92 patients randomized in the first study were included for the 3-year follow-up. The overall morbidity rate in the 2 groups showed that 15 patients (16.3%) had complications with a difference of 6.52 (95% CI, -8.93 to 21.79). Nine patients (19.6%) and 6 patients (13.0%) in the 2-stage Turnbull-Cutait pull-through group and hand-sewn coloanal anastomosis group, respectively, had complications without statistically significant differences (P = .57). Oncological results were comparable between the groups. Long-term fecal continence in the CCA and TCA groups, respectively, assessed using the Wexner Incontinence Score was 10.9 (5.50-15.5) vs 13.0 (7.25-16.0; P = .92), Low Anterior Resection Syndrome score was 32.0 (21.0-37.0) vs 34.0 (23.2-38.5; P = .76), and Colorectal Functional Outcome score was 38.5 (23.0-47.1) vs 40.8 (23.3-58.2; P = .30). In this study, after a 3-year follow-up period, 2-stage Turnbull-Cutait anastomosis for ultralow rectal cancer could be considered as a surgical alternative that has the valuable benefit of avoiding a temporary stoma with similar results in terms of morbidity, fecal continence, patient satisfaction, quality of life, and oncological outcomes when compared with hand-sewn coloanal anastomosis with ileostomy. ClinicalTrials.gov Identifier: NCT01766661.

The Predictors of Surgery for Symptomatic, Atraumatic Full-Thickness Rotator Cuff Tears Change Over Time: Ten-Year Outcomes of the MOON Shoulder Prospective Cohort.

A prospective cohort study was conducted to assess the predictors of failure of nonoperative treatment, defined as the patient undergoing surgery for symptomatic, atraumatic full-thickness rotator cuff tears. We present the 10-year follow-up data of this population to determine if predictors for surgery change over time, and secondarily we report the outcomes of the cohort. At the time of enrollment, demographic, symptom, rotator cuff anatomy, and patient-reported outcome data were collected in patients with symptomatic, atraumatic full-thickness rotator cuff tears. Patients underwent a standard physical therapy protocol for 6 to 12 weeks. Patient data were then collected at 1, 2, 5, 7, and 10 years. Failure of nonoperative treatment was defined as the patient electing to undergo surgery. Of the 452 patients in the original cohort, 20 patients (5%) withdrew from the study, 37 (9%) died before 10 years, and 40 (9%) were otherwise lost to follow-up. A total of 115 patients (27.0%) underwent a surgical procedure at some point during the 10-year follow-up period. Of these patients, 56.5% underwent surgery within 6 months of enrollment and 43.5%, between 6 months and 10 years. Low patient expectations regarding the efficacy of physical therapy were found to be a predictor of early surgery. Workers' Compensation status and activity level were more important predictors of later surgery. Patient-reported outcome measures all improved following physical therapy. For patients who did not undergo a surgical procedure, patient-reported outcome measures did not decline over the 10-year follow-up period. Low patient expectations regarding the efficacy of physical therapy were found to be a predictor of early surgery, whereas Workers' Compensation status and activity level were predictors of later surgery. Physical therapy was successful in >70% of patients with symptomatic, atraumatic full-thickness rotator cuff tears at 10 years. Outcome measures improved with physical therapy and did not decline over the 10-year follow-up period. Prognostic Level I.

Reintroduction to the edge of its range: quenda (Isoodon fusciventer) to Wadderin Sanctuary in the eastern wheatbelt of Western Australia

Context Quenda (bandicoots, Isoodon fusciventer) have shown a major decline in range since European settlement, contracting to the more mesic coastal and forest zones in south-west Western Australia. Key actions to recover this species include broad-scale fox control, cat control and reintroductions. Most reintroductions have been to coastal and forest habitats. Aims To monitor the reintroduction of quenda to fox-free habitat of Wadderin Sanctuary in the wheatbelt of Western Australia, close to the eastern and drier margin of the species’ former range. Methods Relative abundance of the population was monitored over a 12-year period by regular standardised trapping throughout the sanctuary. Key results Quenda were reintroduced in 2010 and have persisted for &gt;12 years. They were protected from fox predation by an exclusion fence, but were subject to a low level of cat predation for the first 8 years. Quenda showed both a ~20% drop in mean body condition over time and a trend of decreasing number of pouch young per female over time, likely a result of a succession of dry years and intra-and inter-specific competition for food resources. However, despite this, the index of abundance suggests that quenda numbers substantially increased, aided by high annual recruitment, in years following removal of the feral cat. Conclusions Quenda appear resilient at this site despite consecutive years of very low rainfall and apparent competition for food resources. Implications Quenda seem able to persist on the drier margin of their former range when protected from high levels of predation.

Genital Burns Are Associated with Worse Psychosocial and Physical Outcomes.

Genital burns are unique and complex injuries that impact patients physically and emotionally. This study investigates the specific impact of genital burns on psychosocial and physical outcomes. A retrospective cohort study was conducted using the TriNetX database, encompassing over 117 million patients from U.S. healthcare institutions. Patients with genital burns were identified and categorized into sub-cohorts based on TBSA and burn degree. Propensity score matching and cohort balancing were performed based on age, gender, race, and ethnicity. Outcomes were analyzed both short-term (1 month) and long-term (5 years), focusing on psychiatric and physical aspects. This study identified 3,496 genital burn patients over a 15-year period. Analyses revealed that genital burns significantly increased short-term risk of death (RR: 2.8), anxiety (RR: 2.656), hospitalization (RR: 2.167), and any anxiety, PTSD, or depression (RR: 2.363), and long-term risk of death (RR: 1.658) and pruritus (RR: 1.58) (all p<0.05). Interestingly, genital burn patients showed a lower risk of chronic joint pain compared to other burn injuries (RR: 0.815) (p<0.05). These results occurred independently of the extent of TBSA. Genital burns have a distinctive impact on patients, leading to higher rates of certain psychiatric morbidities and physical complications. This study highlights the need for tailored care and consideration of the unique challenges faced by patients with genital burns, both in the immediate aftermath and in the long term. Understanding the specific impacts of genital burns is vital for healthcare practitioners to develop care strategies and better support for patients recovering from such injuries.

Single umbilical artery and associated birth defects in perinatal autopsies: prenatal diagnosis and management.

The umbilical cord forms the connection between the fetus and the placenta at the feto-maternal interface and normally comprises two umbilical arteries and one umbilical vein. In some cases, only a single umbilical artery (SUA) is present. This study was conducted to evaluate associations between SUA and other congenital malformations discovered in perinatal autopsies and to ascertain the existence of preferential associations between SUA and certain anomalies. We evaluated records of all fetuses sent for autopsy to the Department of Pathology during the 10-year period from 2013 through 2022 (n = 1,277). The data were obtained from the hospital's pathology laboratory records. The congenital anomalies were grouped by organ or system for analysis and included cardiovascular, urinary tract, nervous system, gastrointestinal tract, musculoskeletal, and lung anomalies. A SUA was present in 8.61% of the autopsies. The gestational age of the affected fetuses ranged between 13 to 40 weeks. An SUA presented as an isolated single anomaly in 44 cases (3.4%). Of the 110 SUA cases, 60% had other congenital anomalies. There was a significant association between birth defects and SUAs (p < .001). Strong associations between SUA and urinary tract, lung, and musculoskeletal anomalies were observed. A SUA is usually seen in association with other congenital malformations rather than as an isolated defect. Therefore, examination for associated anomalies when an SUA is detected either antenatally or postnatally is imperative. The findings of this study should be helpful in counseling expectant mothers and their families in cases of SUA.

Utility of chest x-ray for tracheostomy tube placement in pediatric patients.

To evaluate the utility of ordering chest x-rays after pediatric tracheostomy tube placement in identifying acute, post-operative complications and how it impacts clinical decision-making. In this retrospective cohort study, we identified tracheostomies performed in 139 pediatric patients through CPT codes over a 5-year period from 2013 to 2018. Manual chart review was performed for demographic and clinical characteristics, pre-procedure and post-procedure chest x-ray interpretations, and the presence of complications. Each complication was reviewed to see if action was taken due to post-procedure chest x-ray findings. Multivariable logistic regression was performed to determine associations with changes in pre-procedure versus post-procedure chest x-rays. In a cohort of 139 pediatric patients with pre-procedure and post-procedure chest x-rays, 40 (28.8%) of patients had new significant post-procedure chest x-ray findings compared to pre-procedure chest x-ray findings. Of these 40 instances of changes in pre-procedure versus post-procedure chest x-ray findings, only eight resulted in action being taken due to the observed findings. Among these eight instances of action being taken, only one instance involved in invasive action being taken with a bronchoscopy. With multivariable regression analysis, patient age, race, gender, and the presences of genetic syndromes, were not found to be significant risk factors in predicting changes in pre-procedure versus post-procedure chest x-ray. In our study, post-procedure chest x-ray after tracheostomy tube placement did not significantly impact clinical decision making. It may be worth reconsidering the value in routine chest x-rays after tracheostomy tube placement in pediatric patients.

Is the relationship between chronic pain and mortality causal? A propensity score analysis.

Chronic pain is a serious and prevalent condition that can affect many facets of life. However, uncertainty remains regarding the strength of the association between chronic pain and death and whether the association is causal. We investigate the pain-mortality relationship using data from 19,971 participants aged 51+ years in the 1998 wave of the U.S. Health and Retirement Study. Propensity score matching and inverse probability weighting are combined with Cox proportional hazards models to investigate whether exposure to chronic pain (moderate or severe) has a causal effect on mortality over a 20-year follow-up period. Hazard ratios (HRs) with 95% confidence intervals (CIs) are reported. Before adjusting for confounding, we find a strong association between chronic pain and mortality (HR: 1.32, 95% CI: 1.26-1.38). After adjusting for confounding by sociodemographic and health variables using a range of propensity score methods, the estimated increase in mortality hazard caused by pain is more modest (5%-9%) and the results are often also compatible with no causal effect (95% CIs for HRs narrowly contain 1.0). This attenuation highlights the role of confounders of the pain-mortality relationship as potentially modifiable upstream risk factors for mortality. Posing the depressive symptoms variable as a mediator rather than a confounder of the pain-mortality relationship resulted in stronger evidence of a modest causal effect of pain on mortality (eg, HR: 1.08, 95% CI: 1.01-1.15). Future work is required to model exposure-confounder feedback loops and investigate the potentially cumulative causal effect of chronic pain at multiple time points on mortality.

Human papillomavirus (HPV) vaccination in Japan.

To review the status of human papillomavirus (HPV) vaccination in Japan from inception to the present, focusing on past and current challenges. Published articles and website content related to HPV vaccination were reviewed. The Ministry of Health, Labor and Welfare suspended proactive recommendations for HPV vaccination in June 2013 following repeated media reports of girls experiencing adverse events, including chronic pain and walking disturbances, after receiving the HPV vaccine. Despite later recognition of these symptoms as a functional somatic syndrome, HPV vaccine coverage of target girls aged 12 to 16 years in the National Immunization Program (NIP) rapidly decreased to near zero. This suspension of the proactive HPV vaccination recommendation ceased in fiscal year (f-year) 2022, initiating a 3-year catch-up free HPV vaccination period from April 2022 to March 2025 for women born from f-years 1997 to 2005. These drastic changes were driven by established evidence of the effectiveness and safety of HPV vaccines reported from both Japan and other countries, and a nine-valent HPV vaccine has been included in the NIP since f-year 2023. However, the estimated HPV vaccination rate in the NIP remains low at ≤30%. To regain high coverage of HPV vaccination in Japan, it is essential that government, industry, and academic society work together to raise awareness and educate Japanese people about cervical cancer prevention and HPV-related diseases.

Antidepressant drug use after intensive care: a nationwide cohort study

Modern intensive care has improved survival rates, but emerging evidence suggests a high prevalence of post-intensive care unit (ICU) health problems, including post-traumatic stress disorder, depression and anxiety. These symptoms may have a detrimental effect on quality of life and increase mortality. The primary objective of this study is to examine the extent of initiation of antidepressant medication among ICU survivors and identify the factors associated with its usage. The secondary objective is to investigate whether the use of these medications is linked to an increased mortality. The nationwide study cohort included 125,130 ICU survivors admitted between 2010 and 2017. Within the first 3 months after ICU discharge, 7% of patients initiated antidepressant medication, by 1 year 15.5% had started medication. We found no tendency to a decrease during the 2-year follow-up period. Factors associated with antidepressant use included middle age, female sex, psychiatric and somatic comorbid conditions, substance dependence, higher illness severity, and longer ICU stay. Antidepressant users had a higher mortality rate, and deaths due to external causes and suicide were more frequent in this group. This study emphasizes the importance of detecting and addressing depression in ICU survivors to improve their quality of life and reduce mortality rates.

Enhanced pendulum appliance utilizing temporary anchorage device-based Nance arch and modified springs for optimized molar distalization control: a case report

ABSTRACT A 20-year-old female patient with severe maxillary crowding and skeletal Class III malocclusion was successfully treated using an enhanced pendulum appliance. Camouflage treatment was chosen because the patient refused surgical intervention. Detailed examination and analysis revealed that labial inclination of the maxillary anterior teeth could provide the alignment space necessary after tooth extraction in the maxillary arch but it would not be beneficial esthetically and would increase the moment perpendicular to the tooth long axis as well as increase the risk of bone dehiscence. Therefore, lingual inclination of the mandibular anterior teeth was performed. To create space for aligning the maxillary arch, an enhanced pendulum appliance was utilized, in addition to premolar extraction. The enhanced pendulum appliance had one mesial and one distal helix on each spring, exerting opposing forces in the buccolingual direction and reducing the buccolingual inclination of the molars. In addition, miniscrews were integrated into the Nance arch of the enhanced pendulum appliance to provide skeletal anchorage, minimizing the reciprocal movement of anchorage teeth. This modification not only enhanced control over tooth movement but also improved treatment efficiency. During the entire treatment duration of 17 months, substantial improvement in facial and occlusal aspects were noted. Additionally, the patient retained these positive changes until the subsequent 2-year follow-up period.

Antidepressant drug use after intensive care: a nationwide cohort study

Modern intensive care has improved survival rates, but emerging evidence suggests a high prevalence of post-intensive care unit (ICU) health problems, including post-traumatic stress disorder, depression and anxiety. These symptoms may have a detrimental effect on quality of life and increase mortality. The primary objective of this study is to examine the extent of initiation of antidepressant medication among ICU survivors and identify the factors associated with its usage. The secondary objective is to investigate whether the use of these medications is linked to an increased mortality. The nationwide study cohort included 125,130 ICU survivors admitted between 2010 and 2017. Within the first 3 months after ICU discharge, 7% of patients initiated antidepressant medication, by 1 year 15.5% had started medication. We found no tendency to a decrease during the 2-year follow-up period. Factors associated with antidepressant use included middle age, female sex, psychiatric and somatic comorbid conditions, substance dependence, higher illness severity, and longer ICU stay. Antidepressant users had a higher mortality rate, and deaths due to external causes and suicide were more frequent in this group. This study emphasizes the importance of detecting and addressing depression in ICU survivors to improve their quality of life and reduce mortality rates.
