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.

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.

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.

Existen controversias en la definición de la displasia broncopulmonar, siendo las más utilizadas el requerimiento de O2 durante 28 días o a las 36 semanas de edad gestacional corregida (EGC). Nuestro objetivo fue determinar la incidencia y características clínicas de los prematuros nacidos antes de las 32 semanas (RNP≤ 32s) con requerimiento de O2 a los 28 días de vida (DBP28d) y a las 36 semanas de EGC (DBP36s) en una unidad neonatal de Santiago, Chile, entre los años 2012 y 2019. Es un estudio descriptivo, retrospectivo con componente analítico. La población estudiada incluyó 535 RNP≤ 32s, vivos a las 36 semanas o dados de alta después de las 34 semanas de EGC. De los 242 prematuros DBP28d, 203 (83,88%) fueron DBP36s; 16 de los 242 (6%) requirió O2 durante menos de 28 días consecutivos, de los cuales 7, aún lo requerían a las 36 semanas. Los predictores de DBP36s fueron: sexo masculino (OR 2,42, IC del 95%: 1,24-4,69), peso al nacer (OR 1, IC del 95%: 0,99-1), edad gestacional (OR 0,75, IC del 95%: 0,57-0,97), APGAR a los 5 min, (OR 0,01, IC del 95%: 0,003-0,05), el requerimiento de presión positiva continua o cánula nasal de alto flujo (OR 1,1, IC del 95%: 1,04-1,17) y días de ventilación mecánica invasiva (OR 1,1,95% IC: 1-1,2). Conclusiones: No encontramos una diferencia significativa en la incidencia de DBP entre las definiciones de DBP28d y DBP36s; y la mayoría de los RNP< 32s con diagnóstico de DBP36s se pudieron identificar a los 28 días de vida.
Bronchopulmonary dysplasia (BPD) is the most common chronic lung disease in premature newborns. It is commonly defined as a need for supplemental O2 for 28 days or at 36 weeks postmenstrual age (PMA) (BPD36w). Our objective was to determine the incidence and clinical characteristics of premature neonates born at less than 32 weeks (PNB< 32w) with O2 requirement at 28 days of life (DBP28d) and DBP36w in a neonatal unit of Santiago, Chile, between 2012 and 2019. This is a descriptive, retrospective study with an analytical component. The study population included 535 PNB< 32w, alive at 36 weeks or discharged after 34 PMA. Of the 242 premature BPD28d, 203 (83,88%) were BPD36w; 16 (6%) required O2 for less than 28 consecutive days, of which 7 still required it at 36 weeks. The predictors of BPD36w were: male (OR 2.42, 95% CI: 1.24-4.69), birth weight (OR 1, 95% CI: 0.99-1), gestational age (OR 0.75, 95% CI: 0.57-0.97), APGAR at 5 min, (OR 0.01, 95% CI: 0.003-0.05), continuous positive pressure or high-flow nasal cannula requirement (OR 1.1, 95% CI: 1.04-1.17) and days of invasive mechanical ventilation (OR 1.1, 95% CI: 1-1.2). Conclusions: We did not find a significant difference in the incidence of BPD between the definitions of BPD28d and BPD36s; and the majority of PNB < 32w diagnosed with BPD36w can be identified at 28 days of life.

ABSTRACT Objective: Evaluating clinical factors associated with mortality in older patients who underwent surgical correction of hip fractures. Methods: This observational and retrospective study analyzed the medical records of 67 patients (aged older than 60 years), both men and women, who underwent surgical correction of hip fractures from 2019 to 2020 at Hospital São Paulo. The following variables were analyzed: age, sex, presence of comorbidities, affected hip region, and trauma mechanism. Statistical analyses were performed using the SPSS software. Results: The mean age of patients was 78.12 ± 9.80 years and 80.6% of the sample were women. The prevalence of hip fractures on the right side (52.2%), in the transtrochanteric region (53.7%), and due to fall on the same level (88.1%) was higher. Systemic arterial hypertension (77.6%), diabetes mellitus (37.3%), and dementia (16.4%) were frequent comorbidities. The prevalence of death after fracture was 17.9% and it was associated with longer hospital stay after surgery (p = 0.028). Conclusion: The prevalence of mortality of patients with hip fractures who underwent surgery was 17.9%. A longer hospital stay due to pre-existing comorbidities was the main factor related to this outcome. Level of Evidence III, Retrospective Study.

Abstract The aim of this study was to describe the prevalence, clinicopathological, and prognostic features of acinic cell carcinoma (AciCC) of the oral and maxillofacial region. AciCC cases were retrospectively retrieved from 11 pathology centers of three different countries. Medical records were examined to extract demographic, clinical, pathologic, and follow-up information. A total of 75 cases were included. Females (65.33%) with a mean age of 45.51 years were mostly affected. The lesions usually presented as an asymptomatic (64.28%) nodule (95.66%) in the parotid gland (70.68%). The association of two histopathological patterns was the most common finding (48.93%) and the tumors presented mainly conventional histopathological grades (86.11%). Surgical treatment was performed in the majority of the cases (59.19%). Local recurrence was observed in 20% of the informed cases, regional metastasis in 30.43%, and distant metastasis in 12.50%. The statistical analysis showed that the cases with a solid histopathological pattern (p=0.01), high-grade transformation (p=0.008), recurrence (p=0.007), and regional metastasis (p=0.03) were associated with poor survival. In conclusion, high histopathological transformation, presence of nodal metastasis, and recurrence were prognostic factors for AciCC of the oral and maxillofacial region.

Abstract BACKGROUND: Psoriasis is a systemic, immune-mediated disease characterized by inflammatory manifestations in the skin and joints. Vitamin D deficiency is currently considered a pandemic and is associated with comorbidities including psoriasis and psoriatic arthritis (PsA). OBJECTIVES: To determine the prevalence of hypovitaminosis D [25(OH)D] in patients with plaque psoriasis, with and without PsA, and of independent predictors of serum 25(OH)D levels. DESIGN AND SETTING: Retrospective cross-sectional study conducted among 300 patients at an outpatient clinic in a university center in Juiz de Fora, Minas Gerais, Brazil. METHODS: Demographic and clinical data (psoriasis area and severity index [PASI], family history, age at onset, disease duration, and the presence of PsA according to Classification Criteria for Psoriatic Arthritis), skin phototype, and season of the year were reviewed. RESULTS: Hypovitaminosis D (< 30 ng/mL) was highly prevalent in patients with psoriasis with and without PsA (82.2% and 74.9%, respectively). An inverse correlation between PASI and vitamin D was found (without PsA r = -0.59 and, PsA r = -0.52, P < 0.001), and multivariate regression revealed that hypovitaminosis D was associated with disease severity, season, and phototype. It was confirmed by binary logistic regression between PASI and vitamin D deficiency (< 30 ng/mL), (odds ratio, OR 1.78 CI: -0.20-0.53, P < 0.001). CONCLUSION: Hypovitaminosis D (< 30 ng/mL) was highly prevalent in psoriatic patients with and without PsA. Season and skin phototype were associated with 25(OH)D levels. An inverse association between PASI and serum 25(OH)D levels was established.

@#Introduction: To identify the growth patterns of young children during the first two years of life according to gestational age, birth weight, and growth status at 24 months of age. Methods: This was a retrospective cohort study of 4,570 young children in Selangor. Data were extracted from children’s health records in government health clinics. Growth data were analysed using the Anthro Plus software that utilises the World Health Organization growth standards. Results: Generally, wasting prevalence was the highest at birth and 24 months, but stunting was more predominant from 1 to 21 months. Weight-for-age z-scores (WAZ), lengthfor-age z-scores (LAZ), and weight-for-length z-scores (WLZ) from birth to 24 months were within -3.00 to 0.00 standard deviation (SD) for pre-term low birth weight children, –1.50 to 0.00 SD for pre-term normal birth weight children, and –2.50 to 0.50 SD for full-term low birth weight children. While WAZ, LAZ, and WLZ from birth to 24 months for underweight/stunted/wasted children were within –2.50 to 0.50 SD, the values for overweight/obese (OV/OB) children were within –1.00 to 2.00 SD. For normal children, WAZ, LAZ, and WLZ exhibited comparable trends, with values within –1.00 to 0.00 SD from birth to 24 months. Conclusion: While stunting and wasting persisted as the most common forms of malnutrition in this sample of young children, the prevalence of OV/OB increased by 24 months. Interventions to promote child growth should focus not only on the prevention of undernutrition, but also on OV/OB.

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.

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 compare the effectiveness of areola approach endoscopic thyroidectomy (AET) and conventional open thyroidectomy (OT) in treating papillary thyroid carcinoma.Methods:Four hundred and twenty-eight female patients with papillary thyroid carcinoma who were treated at the Department of General Surgery, Beijing Friendship Hospital between January 2017 and January 2020 were included according to the inclusion and exclusion criteria, of whom 183 underwent AET (AET group) and 245 underwent OT (OT group). Direct comparison and subsequent propensity score matching methodology were utilized to compare the differences between the two operation methods in terms of surgical time, intraoperative parathyroid transplantation rate, intraoperative nerve injury, postoperative complications, reoperation rate, number of lymph node dissections, postoperative lymph node metastasis at 2 years, and route tumor implantation. Data analysis was performed by using SPSS 25.0 software. The metric data of normal distribution was represented by mean ± standard deviation ( ± s), and the t-test was used for between-group comparison. The Chi-test was used for between-group comparison of count data. Results:The AET group had an age of (38.89±9.08) years, weight of (62.10±10.45) kg, and height of (161.97±5.31) cm; the OT group had an age of (45.88±12.47) years, weight of (65.11±12.72) kg, and height of (161.62±5.24) cm. The differences in age, weight, and body mass index between the two groups were statistically significant ( P<0.05). The surgical time in the AET group was (183.00±137.22) min, which was significantly longer than (87.94±28.25) min of the OT group ( t=16.67, P<0.001). The parathyroid transplantation rate in the OT group was significantly higher than that in the AET group (49.39% vs 34.97%, χ2=8.87, P=0.003). There were no statistically significant differences between the two groups in terms of intraoperative nerve injury, postoperative complications, reoperation rate, number of lymph node dissections, postoperative lymph node metastasis at 2 years, and route tumor implantation. After propensity score matching based on differences in age, weight, body mass index, and soon, 183 cases of AET (AET-PS group) and OT (OT-PS group) were obtained for statistical analysis. The surgical time in the AET-PS group was (137.22±32.77) min, which was significantly longer than (90.26±29.35) min of the OT-PS group ( t=14.44, P<0.001). The parathyroid transplantation rate in the OT-PS group was significantly higher than that in the AET-PS group (53.01% vs. 34.97%, χ2=12.08, P=0.001). There were no statistically significant differences between the two groups in terms of intraoperative nerve injury, postoperative complications, reoperation rate, number of lymph node dissections, postoperative lymph node metastasis at 2 years, and route tumor implantation. Conclusions:AET and OT are equally safe and effective in treating papillary thyroid carcinoma. AET surgery can be performed safely and feasibly under strict adherence to surgical principles.
Résumé
Objective:To assess the clinical outcome of patients with spinal tumors who received en bloc resection in our center and to provide theoretical basis for developing novel surgical technique in en bloc resection for spinal tumor.Methods:We retrospectively reviewed the clinical and follow-up data of 113 patients who received en bloc resection for spinal tumors in Musculoskeletal Tumor Center, Peking University People's Hospital from Jan. 2007 to Dec. 2021. There were 68 males and 45 females with an average age of 38.7±16.7 (10-79) years. Primary malignant spinal tumors, primary aggressive spinal tumors and solitary metastatic spinal tumors were diagnosed in 55, 27 and 31 patients, respectively. The surgeries were planned according to the surgical classification for en bloc resection for spinal tumors proposed by Boriani et al, which classified the en bloc resection for spinal tumor into 7 types. The general condition (gender, age, histological diagnosis, location of the lesion, number of involved vertebrae, pre-operative neurological function), surgical procedure (type of surgery, stage of surgery, reconstruction method for anterior structure, duration of surgery, intra-operative haemorrhage, surgical margin), peri- and post-operative complication (intra- and peri-operative complication, post-operative neurological function), and survival [overall survival (OS), recurrence-free survival (RFS) and implant survival (IS)] of patients were retrospectively analyzed.Results:All surgeries accomplished uneventfully except one intra-operative death owing to the haemorrhagic shock caused by injury of major blood vessel. Mean duration of surgery and volume of intra-operative haemorrhage was 517.6±267.4 min and 3802.7±3039.4 ml, respectively. R0 resection was achieved in 48 patients. Three patients died in peri-operative period. Intra- and peri-operative complications were identified in 44 patients (38.9%). 109 patients were followed up with a mean time of 39.4±35.2 months. 27 patients died during follow-up period. The average post-operative overall survival (OS) was 115.4[95% CI (97.9, 133.0)]months and the 5-year OS rate was 64.1%[95% CI (52.3%, 75.9%)]. In patients with primary malignant spinal tumors, the OS of patients with R2 resection was significantly poorer than that of patients with R0/R1 resection ( P=0.024); in patients with metastatic tumors, no difference of OS was observed in patients with different surgical margins ( P=0.612). There were 29 recurrences, and the mean RFS was 105.8 [95% CI (87.5, 124.1)] months. In patients with primary malignant and aggressive spinal tumors, the RFS of patients underwent R2 resection was significantly lower than that of patients underwent R0/R1 resection ( P=0.008, P=0.027); in patients with metastatic spinal tumors, no significant difference of RFS was found in patients with different surgical margin (P=0.707). Conclusion:Although en bloc resection for spinal tumors indicates high morbidity, it significantly improves the OS of patients with primary malignant spinal tumors and the local control of primary malignant and aggressive spinal tumors.
