Prevalence of skin diseases among elderly prisoners in Taiwan: an examination of skin health in prison.

BACKGROUND: Although prisoner health is a topic of significant importance, it has received limited attention in epidemiological studies, likely due to challenges in obtaining data. Therefore, this study aimed to investigate the prevalence of skin diseases among elderly prisoners in Taiwan. METHODS: We examined the presence of skin diseases in 2215 elderly prisoners based on the International Classification of Diseases, 9th revision Clinical Modification (ICD-9-CM). Additionally, the most common types of skin diseases among elderly prisoners in Taiwan were identified. RESULTS: The prevalence of skin diseases among prisoners was estimated to be 55.03%. Elderly men prisoners exhibited a higher prevalence of skin diseases than the women prisoners. The most common skin diseases observed were as follows: contact dermatitis and other forms of eczema; pruritus and related conditions; cellulitis and abscesses; and urticaria. CONCLUSION: Skin diseases were identified in more than half of the elderly prisoners. The overall quality of life of elderly prisoners can be improved by addressing their skin health, which would contribute to the fulfilment of their basic human rights. CLINICAL TRIALS NUMBER: NA.

New infundibulopelvic angle measurement method can predict stone-free rates following retrograde intrarenal surgery.

To enhance the accuracy of predicting stone-free rates after retrograde intrarenal surgery, we devised a novel approach to assess the renal infundibulopelvic angle. We conducted a retrospective review of patient records for those who underwent retrograde intrarenal surgery for renal stones between April 2018 and August 2019. Patient demographics, stone characteristics, and perioperative data were recorded. Subsequently, we introduced a modified angle measurement called the pelvic stone angle and evaluated its predictive performance for stone-free rates by comparing it with the traditional method in scoring systems. A total of 43 individuals were included in this study. Notable differences in stone burden and Hounsfield unit measurements were found between stone-free and non-stone-free patients. The pelvic stone angle demonstrated a good model fit when used in scoring systems, performing equally well as the conventional approach. The area under the receiver operating characteristic curve for the R.I.R.S. scoring system using the pelvic stone angle and the conventional approach did not show a significant difference. In conclusion, the predictive ability of the pelvic stone angle for stone-free rates was comparable to the old measurement method. Moreover, scoring systems using the pelvic stone angle exhibited a better model fit than those using the conventional approach.

The factors impacting on Gleason score upgrading in prostate cancer with initial low Gleason scores.

BACKGROUND: This study aims to investigate the factors contributing to the discrepancy in between biopsy Gleason score (GS) and radical prostatectomy GS in patients diagnosed with prostate cancer. METHODS: 341 patients who underwent radical prostatectomy from 2011/04 to 2020/12 were identified. 102 Patients with initial GS of six after biopsy were enrolled. Preoperative clinical variables and pathological variables were also obtained and assessed. The optimal cut-off points for significant continuous variables were identified by the area under the receiver operating characteristic curve. RESULTS: Upgrading was observed in 63 patients and non-upgrading in 39 patients. In the multiple variables assessed, smaller prostate volume (PV) (p value = 0.0007), prostate specific antigen density (PSAD) (p value = 0.0055), positive surgical margins (p value = 0.0062) and pathological perineural invasion (p value = 0.0038) were significant predictors of GS upgrading. To further explore preclinical variables, a cut-off value for PV (≤ 38 ml, p value = 0.0017) and PSAD (≥ 0.26 ng/ml2, p value = 0.0013) were identified to be associated with GS upgrading. CONCLUSIONS: Smaller PV and elevated PSAD are associated with increased risk of GS upgrading, whereas lead-time bias is not. A cut-off value of PV < 38 ml and PSAD > 0.26 ng/ml2 were further identified to be associated with pathological GS upgrading.

Lipid Profiles Impact on the Oncologic Outcome of Upper Tract Urothelial Carcinoma.

Background: The prognosis of upper tract urothelial carcinoma (UTUC) varies, with T3/T4 UTUC having less than 50% 5-year survival post-radical nephroureterectomy (RNU). Lipid profiles including cholesterol (CHOL), low-density lipoprotein (LDL), and triglycerides (TGs), and high-density lipoprotein (HDL) have shown correlations with oncologic outcomes in various cancers. We aimed to investigate the prognostic significance of the lipid profiles in UTUC patients who had received RNU. Methods: In this retrospective study, a total of 217 UTUC patients who underwent RNU were analyzed. Prognostic factors for overall survival (OS), cancer-specific survival (CSS), and progression-free survival (PFS) were assessed using Cox proportional hazards regression model and competing risk analysis. Results: The median follow-up duration was 2.36 years. Fifty-one (23.50%) of the patients experienced tumor progression, 16 (7.37%) died from UTUC, and 41 (18.89%) died from all causes during the follow-up period. Multivariate analysis revealed that elevated CHOL, low HDL, and elevated TG were linked to worse OS (P = 0.0188, 0.0002, and 0.0001, respectively). Higher CHOL, LDL, and TG, as well as lower HDL significantly affected PFS (P < 0.001 for all), and elevated CHOL and TG were associated with poorer CSS (P = 0.0033 and 0.0179). A competing risk model indicated that elevated LDL increased the risk of cancer progression (P = 0.407), with CHOL increasing the risk of UTUC-specific mortality (P = 0.0162). Limitations include retrospective design, limited, single-time sampling and relatively small sample size. Conclusions: Lipid profiles were identified as prognostic indicators for UTUC patients post-RNU. It highlights the potential importance of lipid management in improving tumor-related outcomes.

A comparison of S.T.O.N.E nephrolithometry scoring system, Guy's stone score, and Seoul National University Renal Stone Complexity (S-ReSC) in predicting mini-PCNL stone-free rate.

The main goal of the study is to evaluate the three stone scoring systems (S.T.O.N.E nephrolithometry scoring system (STONE), Guy's stone score (GSS) and Seoul National University Renal Stone Complexity (S-ReSC)) for the stone-free rate (SFR) of mini-PCNL. We retrospectively analyzed 72 patients who received mini-PCNL from February 2018 to October 2020. The SFR, complication rates, hospitalization days and recurrence rates were analyzed using three stone scoring systems. The result showed statistical significance in the association between scoring system and stone-free (STONE: OR 95%CI 0.409 (0.221-0.759), p = 0.0045; S-ReSC OR 95%CI 0.633 (0.401-0.999), p = 0.0497), but not GSS (OR 95%CI 0.776 (0.397-1.516), p = 0.4581). After adjusting the potential confounding factors, the area under curve (AUC) of STONE, GSS, and S-ReSC was 0.86, 0.78, and 0.81, respectively, and Akaike information criterion (AIC) of STONE, GSS, and S-ReSC was 64.65, 74.89, and 69.92, respectively. The accuracy rate of STONE, GSS, and S-ReSC was 0.81, 0.75, and 0.79, respectively. There was no statistically difference of predicting stone recurrence (p = 0.46, 0.53, 0.86), complications (p = 0.74, 0.51, 0.16) and hospitalization days (p = 0.77, 0.86, 0.87) in STONE, GSS, and S-ReSC, respectively. In conclusion, both the STONE and S-ReSC stone scoring systems are viable for predicting the SFR following mini-PCNL, especially after variable adjustment with the STONE system demonstrating superiority over S-ReSC.

Prevalence of eye and adnexal disorders among elderly inmates in Taiwan prisons.

BACKGROUND: Prisoner health is a topic of significant importance; however, it has received limited attention in epidemiological studies, likely because of challenges in obtaining relevant data. Specifically, research on ocular disorders among elderly prisoners is lacking. Thus, the aim of this study was to evaluate the prevalence of disorders of the eye and adnexa among elderly prisoners in Taiwan. METHODS: We investigated the presence of eye and adnexal disorders in elderly prisoners in Taiwan using data from the Taiwan National Health Insurance Research Database. The ocular disorders were identified using the appropriate disease codes in the International Classification of Diseases, 9th revision Clinical Modification (codes 360-379). In addition, the most common types of eye and adnexal disorders among the prisoners were identified. RESULTS: A total of 2215 elderly prisoners (age ≥ 65 years; 2073 men and 142 women) were examined. The prevalence of eye and adnexal disorders among the prisoners was 18.87%. The elderly female prisoners exhibited a higher prevalence of eye and adnexal disorders than the elderly male prisoners. The most common disorders were disorders of the conjunctiva, cataract, and disorders of the lacrimal system. CONCLUSIONS: A considerable proportion of elderly prisoners have disorders of the eye and adnexa. The overall quality of life of elderly prisoners can be improved by addressing their visual health, which contributes to the fulfillment of their basic human rights.

Gender differences in oral health among prisoners: a cross-sectional study from Taiwan.

BACKGROUND: The prevalence of oral diseases among Taiwanese prisoners has rarely been investigated. This study aimed to estimate the gender-specific prevalence of oral disease in a sample of Taiwanese prisoners. METHODS: We included 83,048 participants from the National Health Insurance (NHI) Program. Outcomes were measured using the clinical version of the International Classification of Diseases, Ninth Revision (ICD-9-CM). For prevalence, we provide absolute values and percentages. We also performed a χ2 test to assess sex and age group differences in the percentage of disease in the oral cavity, salivary glands, and jaw. RESULTS: The prevalence rate of oral diseases was 25.90%, which was higher than that of the general population. The prevalence of oral diseases in female prisoners was higher than that in male prisoners (p < 0.001), and the prevalence of oral diseases in prisoners aged ≤ 40 was higher than that of prisoners aged > 40. Among all cases of diagnosed oral diseases, the top three diseases were dental hard tissue diseases (13.28%), other cellulitis and abscesses (9.79%), and pruritus and related conditions (2.88%), respectively. The prevalence of various oral diseases in female prisoners was significantly higher than that in male prisoners. CONCLUSION: Oral disease is common among Taiwanese prisoners. Female prisoners had a higher prevalence of oral, salivary gland, and jaw diseases than male prisoners. Therefore, early prevention and appropriate treatment are required and also a need for gender-specific oral disease products given the differences in the prevalence of oral disease among male and female prisoners.

Clinical Application of the Peroneal Artery Perforator Flap for Reconstruction of Lateral Malleolus Defects.

The reconstruction of defects of the lateral malleolus involving the exposed fibular bone or tendon is challenging. This study aimed to evaluate the clinical application of the peroneal artery perforator flap with or without split-thickness skin grafting for soft tissue reconstruction of the bony defect of the lateral malleolus of the ankle joints. Reconstruction using a peroneal artery perforator flap with or without split-thickness skin grafting was performed for 15 patients (10 men, 5 women) between January 2007 and December 2018. The mean age was 53.7 years, and the mean size of the flaps was 40 cm2. The flaps were elevated in the form of a perforator flap, and split-thickness skin grafting was performed over the flaps and adjoining raw areas. The flaps survived in all cases; however, partial necrosis was observed in 3 cases. In cases of small-sized defects of the lateral malleolus of the ankle joints where a flap is required for the exposed bone or tendon, reconstruction using the peroneal artery perforator flap is advantageous, since the morbidity rate of the donor site is low and soft tissue is reconstructed.

Kinetics of Phenotype Modification Therapy with VISTA: A Retrospective Case Series Using 3D Digital Analysis

Phenotype modification therapy has emerged as one of the main treatment objectives of periodontal plastic surgery. However, long-term data on the stability of gingival thickness gains are not available. This study examined the kinetics of mucosal thickness gain as a measure of phenotype modification therapy following treatment of multiple gingival recession defects with vestibular incision subperiosteal tunnel access (VISTA). Six patients with 14 recession type (RT) II teeth were treated using VISTA and subepithelial connective tissue grafts (SCTG). Scanned images of study casts at pre- and postoperative periods (6 to 66 months) were digitally superimposed for quantitative evaluation of soft tissue dimensional changes. Mucosal thickness gains ranged from 1.0 ± 0.7 mm (1 mm apical to cement-enamel junction [CEJ]) to 1.4 ± 0.4 mm (5 mm apical to CEJ). The gingival thickness gains remained relatively stable, with thickness gains at 66 months of 0.5 ± 0.8, 0.9 ± 0.6, 1.1 ± 0.6, 1.0 ± 0.4, and 1.2 ± 0.6 mm at 1, 2, 3, 4 and 5 mm apical to the CEJ, respectively. Treatment of multiple gingival recession defects with VISTA and SCTG led to stable gingival thickness gains and shows promise as a strategy for phenotype modification therapy.

Severe cellular stress drives apoptosis through a dual control mechanism independently of p53.

For past two decades, p53 has been claimed as the primary sensor initiating apoptosis. Under severe cellular stress, p53 transcriptional activity activates BH3-only proteins such as Bim, Puma, or Noxa to nullify the inhibitory effects of anti-apoptotic proteins on pro-apoptotic proteins for mitochondrial outer membrane permeabilization. Cellular stress determines the expression level of p53, and the amount of p53 corresponds to the magnitude of apoptosis. However, our studies indicated that Bim and Puma are not the target genes of p53 in three cancer models, prostate cancer, glioblastoma, and osteosarcoma. Bim counteracted with Bcl-xl to activate apoptosis independently of p53 in response to doxorubicin-induced severe DNA damage in prostate cancer. Moreover, the transcriptional activity of p53 was more related to cell cycle arrest other than apoptosis for responding to DNA damage stress generated by doxorubicin in prostate cancer and glioblastoma. A proteasome inhibitor that causes protein turnover dysfunction, bortezomib, produced apoptosis in a p53-independent manner in glioblastoma and osteosarcoma. p53 in terms of both protein level and nuclear localization in combining doxorubicin with bortezomib treatment was obviously lower than when using DOX alone, inversely correlated with the magnitude of apoptosis in glioblastoma. Using a BH3-mimetic, ABT-263, to treat doxorubicin-sensitive p53-wild type and doxorubicin-resistant p53-null osteosarcoma cells demonstrated only limited apoptotic response. The combination of doxorubicin or bortezomib with ABT-263 generated a synergistic outcome of apoptosis in both p53-wild type and p53-null osteosarcoma cells. Together, this suggested that p53 might have no role in doxorubicin-induced apoptosis in prostate cancer, glioblastoma and osteosarcoma. The effects of ABT-263 in single and combination treatment of osteosarcoma or prostate cancer indicated a dual control to regulate apoptosis in response to severe cellular stress. Whether our findings only apply in these three types of cancers or extend to other cancer types remains to be explored.

Evaluation of cooking effects on otolith stable carbon and oxygen isotope values of teleostean fish Pomadasys kaakan (Cuvier, 1830).

RATIONALE: For years, archaeologists, climatologists, and ecologists have used stable oxygen isotope values (δ13 C, δ18 O) in fish otoliths from archaeological sites to reconstruct the habitats, paleo-temperature, and seasonality of the fish captures. Otoliths from archaeological sites might have been heated when ancient people cooked the fish for food. Therefore, there are debates as to whether the cooking behaviors would cause further isotopic fractionations of the carbonate in the otoliths. METHODS: In this study, we have evaluated the effects of the cooking methods on the otolith δ13 C and δ18 O values by comparing the otoliths of the javelin grunter (Pomadasys kaakan) from the same individuals, with the left otoliths taken out before the different cooking processes. Otolith sections of the fish were then made and several subsamples were milled along the microstructures visible in the otolith pairs, mostly annual check rings, followed by the stable isotope analyses. RESULTS: There were no morphological changes between the cooked and uncooked otoliths. The δ13 C and δ18 O values were highly consistent for the otolith subsamples between the cooked and uncooked pairs, suggesting none or trivial effects of the cooking processes on the isotopic values of the otoliths. In addition, some javelin grunters showed lower δ13 C (-5‰ to -6‰) and δ18 O (-4‰ to -5‰) values deposited in the wide translucent zone of the otoliths, suggesting seasonal migration of the fish to estuaries during the summer. CONCLUSIONS: This study suggests that cooking processes do not change otolith stable isotopic compositions and will therefore allow for future research to use the otolith δ13 C and δ18 O values to better understand the life history and used habitats of the preserved fish remains in the middens.

Effect of adalimumab interventions on general infection among adults: a systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: This study assessed the safety of adalimumab in different dosages and durations of treatment. METHODS: We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to explore the infection risk in people who received adalimumab. We searched the Cochrane Library, PubMed, and EMBASE from inception to December 8, 2020. Summary estimates were obtained  using meta-analysis with a random-effects model. RESULTS: Twenty-one RCTs, considered to be of high quality, were analyzed. We found that there was a risk of infection (RR: 1.10, 95% CI: 1.02-1.18). In the stratified analysis, we found an increase in infection among those that received normal dosage (RR: 1.13, 95% CI: 1.04-1.23), and in patients with psoriasis (RR: 1.13, 95% CI: 1.00-1.35) and rheumatoid arthritis (RR: 1.23, 95% CI: 1.06-1.41), but not in those that received high doses and other criteria. In the meta-regressions, intervention duration was not related to changes in incidence risk. CONCLUSIONS: Trials that have a longer treatment duration and higher doses are needed to clarify whether patients that received adalimumab had an elevated risk of general infection.
