Résumé
ABSTRACT Purpose: To evaluate the effectiveness of mapping-targeted biopsies (MTB) on the index lesion for the detection of clinically significant prostate cancer (csPCa) in transperineal fusion-image prostate biopsies. Materials and Methods: A retrospective analysis was conducted on 309 men with suspected PCa who underwent prostate biopsies at the Creu Blanca reference center in Barcelona, Spain. The Prostate Imaging-Reporting and Data System (PI-RADS v.2.1) of the magnetic resonance images (MRI) were reclassified by an expert radiologist reading of pre-biopsy biparametric MRI used for segmentation of suspected lesions. Transperineal MTB of suspicious lesions and 12-core systematic biopsies were performed using the Artemis™ platform. CsPCa was defined as International Society of Urological Pathology grade group ≥ 2. Results: CsPCa was detected in 192 men (62.1%), with detection rates of 6.3% for PI-RADS 2, 26.8% for PI-RADS 3, 87.3% for PI-RADS 4, and 93.1% for PI-RADS 5. MTB of the index lesion identified 185 csPCa (96.3%). CsPCa was detected solely in systematic biopsies in three cases (1.6%), while an additional four cases (2.1%) were identified only in the second suspected lesion. A predictive model for csPCa detection in MTB of the index lesion was developed, with an AUC of 0.918 (95% CI 0.887-0.950). Conclusions: This model had the potential to avoid 23.3% of prostate biopsies without missing additional csPCa cases. MTB of the index lesion was highly effective for identifying csPCa in fusion transperineal prostate biopsies. A developed predictive model successfully reduced the need for almost one quarter of biopsies without missing csPCa cases.

RESUMEN Introducción: La pancreatitis aguda (PA) podría tener características particulares en altitud que pueden afectar su severidad. Objetivo: Describir características clínicas y epidemiológicas de la PA en residentes de altitud. Métodos: Estudio observacional y descriptivo realizado en un hospital a 3 250 metros sobre el nivel del mar (msnm) en Huancayo, Perú. Se incluyeron 129 pacientes con PA entre 2017 y 2021. Se analizaron características clínicas, demográficas y de manejo. Los datos se recolectaron al ingreso y se siguieron hasta el alta hospitalaria. El análisis estadístico se realizó usando SPSS versión 32, describiendo variables cualitativas con frecuencias/porcentajes y cuantitativas con media/desviación estándar o mediana/rangos intercuartílicos según la distribución. Resultados: La edad media fue 45,8 años; el 61,2% fueron mujeres. El IMC medio fue de 26,1 kg/m² y la estancia hospitalaria de 11,1 días. La causa principal de PA fue biliar (78,3%). La media de SaO2 fue 91,6%; de PaO2, 68,7 mmHg; de PaCO2, 29,4 mmHg; de HCO3, 18,8 mEq/L; de hemoglobina, 15,5g; de hematocrito, 46,3%; de TGO, 286,4 U/L y de TGP, 313,9 U/L. La incidencia de PA fue 38,4 casos por cada 10000 ingresos. El 13,2% ingresó a UCI, con una mortalidad del 52,9%. Las complicaciones más frecuentes fueron colecciones peri-pancreáticas (14,7%) y necrosis pancreática (9,3%). La mortalidad global fue 13,9%. Conclusión: La PA en altitud muestra muchas características similares al nivel del mar; empero, las diferencias en SaO2, PaO2, PaCO2, HCO3 y la mortalidad, podría sugerir una influencia de la hipoxia hipobárica que deberá ser corroborada en otros estudios.
ABSTRACT Introduction: Acute pancreatitis (AP) may have particular characteristics at high altitude that can affect its severity. Objetive: To describe the clinical and epidemiological characteristics of AP in residents at high altitude. Methods: Observational and descriptive study conducted in a hospital at 3,250 meters above sea level (masl) in Huancayo, Peru. A total of 129 patients with AP between 2017 and 2021 were included. Clinical, demographic, and management characteristics were analyzed. Data were collected at admission and followed until hospital discharge. Statistical analysis was performed using SPSS version 32, describing qualitative variables with frequencies/percentages and quantitative variables with mean/standard deviation or median/interquartile ranges according to the distribution. Results: The mean age was 45.8 years; 61.2% were women. The mean BMI was 26.1 kg/m², and the hospital stay was 11.1 days. The main cause of AP was biliary (78.3%). The mean SaO2 was 91.6%; PaO2, 68.7 mmHg; PaCO2, 29.4 mmHg; HCO3, 18.8 mEq/L; hemoglobin, 15.5 g; hematocrit, 46.3%; AST, 286.4 U/L; and ALT, 313.9 U/L. The incidence of AP was 38.4 cases per 10,000 admissions. 13.2% were admitted to the ICU, with a mortality rate of 52.9%. The most frequent complications were peri-pancreatic collections (14.7%) and pancreatic necrosis (9.3%). The overall mortality was 13.9%. Conclusion: AP at high altitude shows many similar characteristics to sea level; however, differences in SaO2, PaO2, PaCO2, HCO3, and mortality may suggest an influence of hypobaric hypoxia that should be corroborated in further studies.

Objective:To evaluate the surgery combined chemotherapy and radiation in locally advanced neuroendocrine carcinoma of the cervix (NECC) .Methods:This is a single-center retrospective cohort study. Locally advanced NECC patients admitted to Peking Union Medical College Hospital, Chinese Acadmy of Medical Sciences from January 2011 to April 2022 were enrolled. They were divided into concurrent chemoradiotherapy group, and surgery combined with chemotherapy and radiation group. The Kaplan-Meier method was used to analyze the progression free survival (PFS), overall survival (OS), recurrence rate, and mortality rate.Results:(1) Forty-six cases were included, 22 in concurrent chemoradiotherapy group, 24 in surgery combined chemotherapy and radiation group. With 16 patients (35%, 16/46) received neoadjuvant chemotherapy (NACT), the NACT effective rate was 15/16. (2) The median follow-up time was 27.5 months (range: 10-106 months), with 26 (57%, 26/46) experienced recurrences. There were 4 (9%, 4/46) pelvic recurrences and 25 (54%, 25/46) distant recurrences, and 3 (7%, 3/46) both pelvic and distant recurrences. Compared with concurrent chemoradiotherapy group, surgery combined chemotherapy and radiation group had lower pelvic recurrence rate [14% (3/22) vs 4% (1/24); χ2=1.296, P=0.255] but without statistic difference. Both groups had similar distant recurrence rate [55% (12/22) vs 54% (13/24); χ2=0.001, P=0.979] and overall recurrence rate [59% (13/22) vs 54% (13/24); χ2=0.113, P=0.736]. (3) During the follow-up period, 22 cases (48%, 22/46) died, with 11 cases (50%, 11/22) in concurrent chemoradiotherapy group and 11 cases (46%, 11/24) in surgery combined chemotherapy and radiation group, without significant difference ( χ2=0.080, P=0.777). The postoperative 3-year and 5-year OS rates were 62.3% and 36.9%. Compared with concurrent chemoradiotherapy group, the patients in surgery combined chemotherapy and radiation group showed an extended trend in PFS (17.0 vs 32.0 months) and OS (37.0 vs 50.0 months) but without statistic differences ( P=0.287, P=0.125). Both groups had similar 3-year OS rate (54.2% vs 69.9%; P=0.138) and 5-year OS rate (36.1% vs 38.8%; P=0.217). Conclusions:Our study supports the multi-modality treatment strategy (including surgery, chemotherapy and radiation) as an important component in the treatment of locally advanced NECC. The combination of surgery, chemotherapy and radiation seems to have advantages in the treatment of locally advanced NECC, but needs to be confirmed by further multicenter studies.

Objective:To analyze the incidence, epidemiology, and clinical characteristics of Creutzfeldt-Jakob disease (CJD) in Guizhou Province from 2017 to 2021 and provide a scientific basis for monitoring of CJD in Guizhou Province.Methods:In this retrospective study, epidemiological and clinical information on suspected CJD cases reported by nine hospitals in Guizhou Province was collected and analyzed based on the laboratory test results of cerebrospinal fluid, blood, and skin samples from the patients.Results:From 2017 to 2021, a total of 47 patients with suspected CJD were reported in Guizhou Province, including 22 confirmed patients. Of these patients, 18 patients (18/22) were clinically diagnosed with sporadic CJD, 2 patients (2/22) were clinically suspected of having sCJD, and 2 patients (2/22) were confirmed to have genetic CJD. All patients primarily presented with rapid progressive dementia, and abnormal magnetic resonance imaging findings of the head are the main auxiliary examination results (16/20). The positive rate of 14-3-3 protein in cerebrospinal fluid was high (14/21). The blood sample PRNP gene testing revealed that 129 amino acids were M/M homozygous, while 219 amino acids were E/E homozygous. Except for T188K and E200K mutations detected by PRNP gene testing in 2 gCJD cases, no other site mutations were found, and 5 cases were positive for skin PrPSc. Patients' geographical distribution showed no obvious clustering. Patients have a wide range of occupations. The male-to-female ratio was 13:9, with a median age of 64 years. The majority of the patients were Han Chinese, and there was no special epidemiological history. Conclusion:The majority of the confirmed CJD patients in Guizhou Province from 2017 to 2021 are sporadic CJD patients, and their residence, occupation, gender ratio, age distribution, and other characteristics are consistent with the incidence patterns of sporadic CJD.

Objective:To explore the effects of amlodipine combined with different doses of atorvastatin and simvastatin on hypertension complicated by atherosclerosis.Methods:A retrospective analysis was conducted on the clinical data of 100 patients with hypertension complicated by atherosclerosis who were diagnosed and treated at Jinan 2 nd People's Hospital from August 2019 to August 2020. These patients were divided into control group ( n = 32, amlodipine combined with simvastatin), study group 1 ( n = 34, amlodipine combined with 10 mg/day atorvastatin), and study group 2 ( n = 34, amlodipine combined with 20 mg/day atorvastatin) according to different treatment schemes. All three groups were treated for 6 months. The clinical efficacy, blood lipid level, blood pressure, oxidative stress level, carotid intima-media thickness and plaque area were compared among the three groups. Results:The overall response rates of the control group, study group 1, and study group 2 were 71.88% (23/32), 82.35% (28/34), and 91.18% (31/34), respectively. The difference in overall response rate among the three groups was statistically significant ( χ2 = 4.16, P < 0.05). After treatment, total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, 24-hour dynamic blood pressure, diurnal blood pressure, nighttime blood pressure, malondialdehyde, superoxide dismutase, glutathione peroxidase, carotid intima-media thickness and plaque area were statistically different among the three groups ( F = -19.54, -76.61, 11.15, -56.83, -147.35, -23.10, -11.47, -11.65, -128.36, -15.60, -24.52, 25.61, 118.99, -59.23, -81.64, all P < 0.05). The incidence rates of adverse reactions in the control group, study group 1, and study group 2 were 12.50% (4/32), 8.82% (3/34), and 11.76% (4/34), respectively. There was no statistically significant difference among the three groups ( χ2 = 0.25, P = 0.611). Conclusion:Amlodipine combined with atorvastatin is more effective in the treatment of hypertension complicated by atherosclerosis than the amlodipine combined with simvastatin. High-dose atorvastatin is more effective in reducing lipid, controlling blood pressure, improving the level of oxidative stress and clinical symptoms compared with low-dose atorvastatin.

Objective:To investigate the predictive value of preoperative aspartate aminotransferase to alanine aminotransferase ratio (AAR) for early recurrence after radical resection of single small hepatocellular carcinoma.Methods:A retrospective cohort study was conducted to analyze the clinical data of 137 patients who underwent radical resection of liver cancer at the General Hospital of Ningxia Medical University from January 2017 to July 2021. These patients were categorized into a recurrence group ( n = 72) and a non-recurrence group ( n = 65) based on early postoperative recurrence. Univariate and multivariate logistic regression analyses were conducted in the training cohort to identify independent risk factors for early recurrence of small hepatocellular carcinomas. Subsequently, the AARs were grouped, and patients with similar propensity scores estimated by the logistic model were matched 1:1 using the Propensity Score Match method with a caliper value of 0.02 to eliminate confounders. Logistic regression analysis was then repeated to assess the predictive value of the matched AAR for postoperative recurrence in patients with single small hepatocellular carcinoma. Results:Univariate analysis revealed that age ( χ2 = 4.22, P = 0.040), the ratio of fibrinogen to albumin ( χ2 = 8.26, P = 0.004), and the AAR ( χ2 = 5.83, P = 0.016) were significantly associated with early recurrence of small liver cancer after radical resection. Multivariate logistic regression analysis further identified age ( P = 0.042), the ratio of fibrinogen to albumin ( P = 0.024), and the AAR ( P = 0.018) as independent risk factors for early recurrence of single small hepatocellular carcinoma following radical surgery. After excluding confounding factors using the Propensity Score Match method, 25 patient pairs were successfully matched. Post-matching logistic regression analysis revealed that an AAR > 0.74 ( P = 0.005) and age > 60 years ( P = 0.024) were independent risk factors for early recurrence in patients with single small hepatocellular carcinoma following radical resection. Conclusion:Preoperative AAR is an independent risk factor for early recurrence in patients with single small hepatocellular carcinoma following surgery, demonstrating excellent predictive value.

ABSTRACT Introduction: The impact of mitral regurgitation (MR) on valve-in-valve transcatheter aortic valve implantation (VIV-TAVI) in patients with failed bioprostheses remains unclear. The purpose of this study was to assess the prognostic impact of residual moderate MR following VIV-TAVI. Methods: We retrospectively analyzed 127 patients who underwent VIV-TAVI between March 2010 and November 2021. At least moderate MR was observed in 51.2% of patients before the procedure, and MR improved in 42.1% of all patients. Patients with postoperative severe MR, previous mitral valve intervention, and patients who died before postoperative echocardiography were excluded from further analyses. The remaining 114 subjects were divided into two groups according to the degree of postprocedural MR: none-mild MR (73.7%) or moderate MR (26.3%). Propensity score matching yielded 23 pairs for final comparison. Results: No significant differences were found between groups before and after matching in early results. In the matched cohort, survival probabilities at one, three, and five years were 95.7% vs. 87.0%, 85.0% vs. 64.5%, and 85.0% vs. 29.0% in the none-mild MR group vs. moderate MR-group, respectively (log-rank P=0.035). Among survivors, patients with moderate MR had worse functional status according to New York Heart Association (NYHA) class at follow-up (P=0.006). Conclusion: MR is common in patients with failed aortic bioprostheses, and improvement in MR-status was observed in over 40% of patients following VIV-TAVI. Residual moderate MR after VIV-TAVI is not associated with worse early outcomes, however, it was associated with increased mortality at five years of follow-up and worse NYHA class among survivors.

ABSTRACT Objective: The purpose of this retrospective study was to compare accuracy of arch expansion using two different thermoplastic materials in Invisalign aligners: EX30® (Polyethylene Terephthalate Glycol, or PETG) and SmartTrack® (polyurethane). Methods: The study sample comprised 65 adult patients consecutively treated with Invisalign from two private practices: group 1 - treated with EX30® (358 teeth) and group 2 - treated with SmartTrack® (888 teeth). Six hundred and twenty-three measurements were assessed in three digital models throughout treatment: model 1 - initial, model 2 - predicted tooth position, and model 3 - achieved position. Sixteen reference points per arch were marked and, after best alignment, 2 points per tooth were copied from one digital model to another. Linear values of both arches were measured for canines, premolars, and first molars: on lingual gingival margins and cusp tips of every tooth. Comparisons were performed by Wilcoxon and Mann-Whitney test. Results: Both termoplastic materials presented significant differences between predicted and achieved values for all measurements, except for the lower molar cusp tip in the SmartTrack® group. There is no statistical difference in the accuracy of transverse expansion between these two materials. Overall accuracy for EX30® aligners in maxilla and mandible were found to be 37 and 38%, respectively; and Smarttrack® presented an overall accuracy of 56.62% in the maxilla and 68.72% in the mandible. Conclusions: It is not possible to affirm one material expands better than the other. Further controlled clinical studies should be conducted comparing SmartTrack® and EX30® under similar conditions.
RESUMO Objetivo: O objetivo deste estudo retrospectivo foi comparar a acurácia na expansão da arcada utilizando alinhadores Invisalign com dois tipos de material termoplástico: EX30® (Polietileno Tereftalato Glicol, ou PETG) e SmartTrack® (poliuretano). Método: A amostra desse estudo incluiu 65 pacientes adultos tratados consecutivamente em dois consultórios particulares: grupo 1 - tratado com EX30® (358 dentes), e grupo 2 - tratado com SmartTrack® (888 dentes). Foram avaliadas 623 medidas em três pares de modelos digitais, ao longo do tratamento: modelo 1 - inicial, modelo 2 - posição dentária planejada, modelo 3 - posição alcançada. Foram marcados 16 pontos de referência por arcada e, após o bestfit, 2 pontos por arcada foram copiados de um modelo digital para o outro. Medidas lineares de ambas as arcadas foram aferidas para caninos, pré-molares e primeiros molares, localizadas na margem gengival lingual e ponta de cúspide de todos os dentes. Foram realizadas comparações usando os testes Wilcoxon e Mann-Whitney. Resultados: Ambos os materiais termoplásticos apresentaram diferenças significativas entre os valores planejados e alcançados em todas as medidas, exceto na ponta de cúspide dos primeiros molares inferiores do grupo SmartTrack®. Não houve diferença estatística entre esses dois materiais quanto à acurácia da expansão transversa. Em termos gerais, a acurácia dos alinhadores EX30® na maxila e mandíbula foi de 37% e 38%, respectivamente. O grupo SmartTrack® apresentou acurácia de 56,62% e 68,72% na maxila e mandíbula, respectivamente. Conclusões: Não foi possível afirmar que um material expande melhor que o outro. Estudos clínicos controlados futuros devem ser conduzidos comparando SmartTrack® e EX30® sob condições similares.

ABSTRACT Objective: This retrospective study aimed to assess the predictability of Invisalign® aligners regarding rotational, mesio-distal and buccal-lingual tip movements. Methods: Two materials were included in the analysis - EX30, used until 2013; and SmartTrack, in current use. The study comprised 56 adult patients treated with Invisalign Comprehensive. Data sample were assessed on three sets of digital models; model 1 - initial, model 2 - predicted, and model 3 - achieved. Sixty reference points were marked in each dental arch, and two reference planes assisted the superimposition. The degree of rotation, mesio-distal and buccal-lingual tip was obtained via trigonometric calculations, through a previously published validated method. The accuracy of outcomes was compared according to the types of tooth movement and teeth groups,and the influence of predetermined variables on movement accuracy was also investigated. Results: Rotation and mesio-distal tip did not present any significant difference when comparing EX30 and SmartTrack groups. Only buccal-lingual tip presented a significant difference, incisor and canine groups treated with EX30 aligners presented an increase in accuracy (p= 0.007 and p = 0.007, respectively). For each additional degree planned for rotation movements, there was an increase of 0.35° in the discrepancy, and an increase of 0.40° and 0.41° for mesio-distal and buccal-lingual tip, respectively. EX30 and SmartTrack discrepancies were compared by multilevel linear regression. Conclusion: EX30 aligners reached higher accuracy for buccal-lingual tip in anterior teeth. However, for rotation and mesio-distal tip, SmartTrack and EX30 are similarly accurate. The total amount of planned movement has a significant impact on accuracy rates, with a decrease in accuracy for every additional degree.
RESUMO Objetivo: Esse estudo retrospectivo teve como objetivo aferir a previsibilidade dos alinhadores Invisalign em relação aos movimentos de rotação e inclinações mesiodistal e vestibulolingual. Material e Métodos: Foram incluídos dois materiais nessa análise: EX30®, utilizado até 2013; e SmartTrack®, atualmente em uso. Esse estudo avaliou 56 pacientes tratados com Invisalign Comprehensive. Os dados foram avaliados em três pares de modelos digitais; modelo 1 - inicial, modelo 2 - planejado, e modelo 3 - alcançado. Foram marcados 60 pontos de referência em cada arcada, sendo a sobreposição realizada com auxílio de planos de referência. O grau de rotação e inclinações mesiodistal e vestibulolingual foi obtido por cálculos de trigonometria, usando um método validado publicado anteriormente. Os resultados foram comparados de acordo com os tipos de movimento dentário e grupos de dentes, também foi investigada a influência de variáveis predeterminadas na confiabilidade dos movimentos. Resultados: Os movimentos de rotação e inclinação mesiodistal não apresentaram diferença estatística, quando comparados os grupos EX30® e SmartTrack®. Somente a inclinação vestibulolingual apresentou diferença estatisticamente significativa, sendo que os grupos de incisivos e caninos tratados com alinhadores EX30® apresentaram um aumento na previsibilidade(p= 0,007 e p= 0,007, respectivamente). Para cada grau adicional planejado para movimento de rotação, ocorreu um aumento de 0,35° na discrepância, e aumentos de 0,40° e 0,41° para as inclinações mesiodistal e vestibulolingual, respectivamente. As discrepâncias entre EX30® e SmartTrack® foram comparadas por regressão linear multinível. Conclusão: Os alinhadores EX30® alcançaram maior previsibilidade para a inclinação vestibulolingual em dentes anteriores. No entanto, para rotação e inclinação mesiodistal, SmartTrack® e EX30® apresentaram previsibilidade similar. A quantidade total de movimento planejado apresenta influência significativa nas taxas de previsibilidade, com diminuição na acurácia para cada grau adicional.

ABSTRACT Objective: To analyze the temporal trend of tuberculosis cure indicators in Brazil. Methods: An ecological time-series study using administrative data of reported cases of the disease nationwide between 2001 and 2022. We estimated cure indicators for each federative unit (FU) considering individuals with pulmonary tuberculosis, tuberculosis-HIV coinfection, and those in tuberculosis retreatment. We used regression models using joinpoint regression for trend analysis, reporting the annual percentage change and the average annual percentage change. Results: For the three groups analyzed, we observed heterogeneity in the annual percentage change in the Brazilian FUs, with a predominance of significantly decreasing trends in the cure indicator in most FUs, especially at the end of the time series. When considering national indicators, an average annual percentage change of −0.97% (95% CI: −1.23 to −0.74) was identified for the cure of people with pulmonary tuberculosis, of −1.11% (95% CI: −1.42 to −0.85) for the cure of people with tuberculosis-HIV coinfection, and of −1.44% (95% CI: −1.62 to −1.31) for the cure of people in tuberculosis retreatment. Conclusions: The decreasing trends of cure indicators in Brazil are concerning and underscore a warning to public authorities, as it points to the possible occurrence of other treatment outcomes, such as treatment discontinuity and death. This finding contradicts current public health care policies and requires urgent strategies aiming to promote follow-up of patients during tuberculosis treatment in Brazil.

ABSTRACT Introduction: Limited options in the end-stage treatment of heart failure have led to increased use of left ventricular assist devices. For this reason, the rate of non-cardiac surgeries in patients with left ventricular assist devices is also increasing. Our study aims to analyze surgical rate, anesthesia management, and results by reviewing our 11-year experience with patients who underwent non-cardiac surgery receiving left ventricular assist devices support. Methods: We retrospectively evaluated 57 patients who underwent non-cardiac surgery and 67 non-cardiac surgical procedures among 274 patients who applied between January 2011 and December 2022 and underwent left ventricular assist devices implantation with end-stage heart failure. Results: Fifty (74.6%) patients with left ventricular assist devices admitted to the hospital for non-cardiac surgery were emergency interventions. The most common reasons for admission were general surgery (52.2%), driveline wound revision (22.3%), and neurological surgery (14.9%). This patient group has the highest in-hospital mortality rate (12.8%) and the highest rate of neurological surgery (8.7%). While 70% of the patients who underwent neurosurgery were taken to surgery urgently, the International Normalized Ratio values of these patients were between 3.5 and 4.5 at the time of admission to the emergency department. Conclusion: With a perioperative multidisciplinary approach, higher morbidity and mortality risks can be reduced during emergencies and major surgical procedures.
Résumé
Introduction. Multidrug-resistant/rifampicin-resistant tuberculosis (MDR/RR-TB) is difficult to control, has high morbidity and mortality, and demands priority public health intervention. In Colombia, MDR/RR-TB has been becoming more widespread annually. Before the COVID-19 pandemic, over an 8-year period, the number of cases of multidrug-resistant tuberculosis in Colombia was close to a thousand cases. Timely identification of the different risk factors for MDR/RR-TB will contribute fundamentally to the systematic management. Objective. To determine which risk factors were associated with the presentation of MDR in Colombia between 2013 and 2018. Materials and methods. A retrospective case-control study was carried out, for which the data from the routine surveillance of MDR/events in the country were used. Results. The cases of multidrug-resistant tuberculosis were mainly in young people, Afrodescendants, and males. Of the clinical conditions, comorbidities such as malnutrition, diabetes, and HIV, presence of at least one factor, such as drug dependence, taking immunosuppressive medications, belonging to the black race, afro, and living in an area of high disease burden were risk factors. Conclusion. In addition to the diagnosis and timely provision of MDR-TB treatment, it is necessary that public health programs at the local level pay special attention to patients with the identified risk factors.

ABSTRACT BACKGROUND: Hypovitaminosis D is a public health problem associated with several chronic inflammatory and immunological diseases, including psoriasis. OBJECTIVES: This study aimed to determine the prevalence of hypovitaminosis D in patients with plaque psoriasis. A comparison was made between vitamin D levels in patients with psoriasis and those with other non-inflammatory dermatoses without photosensitivity. In addition, it evaluated the effects of the patients' Fitzpatrick skin phototype and the season of the year on the serum levels of vitamin D. DESIGN AND SETTINGS: A retrospective cross-sectional study was conducted at an outpatient clinic in a university center in Juiz de Fora (MG), Brazil. METHODS: A review of dermatology patients' demographic data, including skin phototype and serum levels of 25-hydroxyvitamin D [25(OH)D], over 12 months in 2016. RESULTS: This study included 554 patients: 300 patients allocated to the plaque psoriasis group and 254 control patients with other dermatological diseases. Regarding the season of the year, 229, 132, 62, and 131 participants were evaluated in summer, autumn, winter, and spring, respectively. As for the skin phototype, 397, 139, and 18 patients had phototypes III, IV, and V, respectively. The serum levels of 25(OH)D were significantly lower in the psoriasis group (24.91 ± 7.16 ng/mL) than in the control group (30.37 ± 8.14 ng/mL). CONCLUSIONS: Hypovitaminosis D (< 30 ng/mL) was present in 76.66% of patients with psoriasis versus 53.94% of control patients. Vitamin D deficiency (< 20 ng/mL) was observed in 25% of the patients with psoriasis versus 8.66% in the control group (P < 0.001). The season and patient's skin phototype were independent predictors of serum vitamin D levels.

Objective@#To analyze the trends and influencing factors of endurance performance of 19-22 years old college students in Hunan Province from 1985 to 2019, so as to provide objective and scientific basis for sports and health work in colleges and universities.@*Methods@#A retrospective analysis was conducted on the data of 14 490 college students aged 19-22 in Hunan Province from 8 consecutive National Student Physical Fitness and Health Surveys conducted from 1985 to 2019. The analysis indexes were 1 000 m running for boys and 800 m running for girls.@*Results@#From 1985 to 2019, the endurance running time of 19-22 years old Han college students in Hunan Province showed an obvious trend of decline. The 1 000 m running time of urban and rural male students increased by 41.9 and 45.4 s on average, and the 800 m running time of urban and rural female students increased by 29.5 and 30.6 s on average, respectively. Multiple linear regression analysis showed that age ( β =0.17), urban students (rural students as reference; β =0.44), GDP ( β =0.94) and urbanization level ( β = 0.44 ) were positively correlated with the average endurance running time of males. Urban students ( β =0.92), GDP ( β = 1.38 ) and Engel coefficient ( β =0.93) were positively correlated with the average endurance running time of females. BMI ( β =-0.47) was negatively correlated with the females mean time of endurance running ( P ＜0.05).@*Conclusion@#The endurance performance of Han college students in Hunan Province showed a declining trend from 1985 to 2019,which is associated with age, urban and rural distribution, regional GDP, Engel s coefficient, urbanization level and BMI. Effective measures should be taken to improve the physical quality of college students.

Objective: To analyze the serum carbohydrate antigen 125 (CA125) level and its influencing factors in male silicosis patients with pulmonary heart disease. Methods: In October 2021, data of 38 male patients with simple silicosis (silicosis group), 28 cases of silicosis with pulmonary heart disease (pulmonary heart disease group), and 27 healthy controls (control group) in the same age group were collected in inpatient and outpatient of Nanjing Occupational Disease Prevention and Control Hospital from January 2017 to December 2020. The serum CA125 levels of the three groups were compared, and the correlation between disease-related indexes and serum CA125 in silicosis patients with pulmonary heart disease was analyzed, as well as the influencing factors of pulmonary heart disease and serum CA125 levels in silicosis patients. Results: The serum CA125 level[ (19.95±7.52) IU/ml] in pulmonary heart disease group was higher than that in silicosis group[ (12.98±6.35) IU/ml] and control group[ (9.17±5.32) IU/ml] (P<0.05). There was no significant difference in serum CA125 level between the silicosis group and the control group (P>0.05). Serum CA125 levels were positively correlated with blood uric acid and fasting blood glucose in silicosis patients with pulmonary heart disease (r=0.39, 0.46, P<0.05). Serum CA125 level was a risk factor for silicosis patients with pulmonary heart disease (OR=1.13, 95%CI: 1.02-1.24, P<0.05). Dust exposure time, lactate dehydrogenase and smoking history were positively correlated with serum CA125 level in silicosis patients (P<0.05) . Conclusion: The serum CA125 level of male silicosis patients with pulmonary heart disease is significantly increased, and the level of CA125 is correlated with the level of fasting blood glucose and blood uric acid.

Objective: To analyze the case characteristics of Chronic obstructive pulmonary disease caused by occupational irritant chemicals (OI-COPD). To provide basis for revising its diagnostic criteria. Methods: From June to December 2021, we investigated the information of OI-COPD patients confirmed by Shandong Institute of Occupational Health and Prevention of Occupational Diseases, Guangxi Zhuang Autonomous Region Institute of Occupational Disease Prevention and Control, Qingdao Central Hospital affiliated to Qingdao University and other diagnostic institutions in the past five years, a total of 41 cases. The basic information of OI-COPD cases, occupational risk factors exposure information, medical history, smoking history and clinical symptoms were analyzed retrospectively. The measurement data were tested for normal distribution, which was described by x±s, and compared between groups by t test; Those who do not conform to the normal distribution are described by the median [M (Q(1), Q(3)) ] and analyzed by nonparametric test; The counting data were expressed in frequency and rate (% ), and the comparison between groups was tested. Results: Of the 41 cases, 33 were male and 8 were female. The age of the patient diagnosed with OI-COPD was (49.5±10.3) years old, and the minimum age was 30 years old; Among them, 8 patients had a definite long-term smoking history (more than 5 years) ; The exposure duration of occupational risk factors was (18.6±10.3) years, of which 3 patients had exposure duration of less than 5 years; The occupational risk factors leading to OI-COPD include acids and acid-forming compounds, bases, aldehydes, nitrogen oxides, chlorine and its compounds, etc. The exposure level of occupational risk factors is related to the degree of COPD airflow restriction (χ(2)=6.17, P <0.05). 18 patients with diagnosis age <50 years old were diagnosed as early-onset COPD. The incidence of respiratory symptoms in the early diagnosis COPD group was lower than that in the non-early diagnosis COPD group, and the FEV1% pred was significantly higher than that in the non-early diagnosis COPD group. The difference was statistically significant (P<0.01 ) . Conclusion: The exposure level of occupational risk factors may be the risk factor affecting the degree of COPD airflow restriction. With the increase of the exposure level of COPD patients, the proportion of respiratory symptoms will also increase accordingly.
