Introduction: Subtotal Parathyroidectomy (S-PTx) and total Parathyroidectomy with immediate Autograft (PTx-AG) are well-established techniques for the treatment of refractory Secondary Hyperparathyroidism (SHPT), with comparable improvements in patients' quality of life and survival. However, the long-term costs after these operations may impact the choice of surgical technique. The objective of the study is to analyze the impact of surgical treatment on medication costs and whether there is any difference between medication use after each procedure, considering impacts on the health system.

Material and methods: Prospective and randomized study in patients with severe SHPT undergoing S-PTx and PTx-AG. Analysis of prescribed medication costs in the month before the postoperative period at 1-, 3-, 6-, 12-, and 18 months. Costs were estimated according to government payment system values. The medications of 65 patients after PTx-AG were compared with those of 24 patients after S-PTx. A comparison of the total costs of the period between 38 men and 51 women was also made.

Results: There were 89 evaluable cases. Surgery reduced medication costs after 12 months. The median of total drug costs in the analyzed period was R$ 8,375.00 per patient. There was no difference in costs per patient in the S-PTx group compared to the PTx-AG group. The median total costs were R$ 11,063.0 for men and R$ 7,651.0 for women (p = 0.0078).

Conclusions: The type of parathyroidectomy did not impact costs after surgery. In the first year after surgery, the use of calcium and calcitriol was more significant than the use of other medications. In the following months, the use of sevelamer is responsible for the highest costs. Men have higher costs in outpatient follow-up after surgery.

Introduction: Candida auris is a globally disseminated invasive ascomycetous yeast, that imposes a substantial burden on healthcare systems. It has been documented to have spread to over 40 countries across six continents, necessitating in-depth comprehension through advanced techniques like Whole-Genome Sequencing.

Method: This study entailed the isolation and Whole-Genome Sequencing of a fluconazole-resistant C. auris strain (CA01) obtained from a patient's blood in Beijing. Genome analysis was conducted to classify the strain, and molecular docking was performed to understand the impact of mutations on drug resistance.

Results: Genome analysis revealed that CA01 belongs to the South Asia Clade (I) and shares the closest genetic relationship with previously reported strains BJCA001 and BJCA002. Notably, unlike BJCA001, CA01 exhibits significant resistance to fluconazole primarily due to the A395T mutation in the ERG11 gene. Molecular docking studies demonstrated that this mutation leads to geometric changes in the active site where fluconazole binds, resulting in decreased binding affinity. Additionally, the present findings have identified several core virulence genes in C. auris, such as RBF1.

Discussion: The findings from this study expand the understanding of the genetic diversity and adaptive mechanisms of C. auris within the South Asia Clade (I). The observed fluconazole resistance driven by the ERG11 mutation A395T highlights the need for heightened awareness and adaptation in clinical treatment strategies in China. This study provides critical insights into drug resistance and virulence profiles at a genetic level, which could guide future therapeutic and management strategies for C. auris infections.

Objective: This study investigated the significance of serum hypoxia-inducible factor (HIF)-1α/HIF-2 α and Chitinase 3-Like protein 1 (YKL-40) levels in the assessment of vascular invasion and prognostic outcomes in patients with Follicular Thyroid Cancer (FTC).

Methods: This prospective study comprised 83 patients diagnosed with FTC, who were subsequently categorized into a recurrence group (17 cases) and a non-recurrence group (66 cases). The pathological features of tumor vascular invasion were classified. Serum HIF-1α/HIF-2α and YKL-40 were quantified using a dual antibody sandwich enzyme-linked immunosorbent assay, while serum Thyroglobulin (Tg) levels were measured using an electrochemiluminescence immunoassay method. The Spearman test was employed to assess the correlation between serum factors, and the predictive value of diagnostic factors was determined using receiver operating characteristic curve analysis. A Cox proportional hazards regression model was utilized to analyze independent factors influencing prognosis.

Results: Serum HIF-1α, HIF-2α, YKL-40, and Tg were elevated in patients exhibiting higher vascular invasion. A significant positive correlation was observed between Tg and HIF-1α, as well as between HIF-1α and YKL-40. The cut-off values for HIF-1α and YKL-40 in predicting recurrence were 48.25 pg/mL and 60.15 ng/mL, respectively. Patients exceeding these cut-off values experienced a lower recurrence-free survival rate. Furthermore, serum levels surpassing the cut-off value, in conjunction with vascular invasion (v2+), were identified as independent risk factors for recurrence in patients with FTC.

Conclusion: Serum HIF-1α/HIF-2α and YKL-40 levels correlate with vascular invasion in FTC, and the combination of HIF-1α and YKL-40 predicts recurrence in patients with FTC.

Introduction: Considering the relationship between Gestational Diabetes Mellitus and maternal and perinatal adverse outcomes, it's pertinent to investigate whether this diagnosis is a predictor of fear of childbirth. As there is little data about the fear of childbirth in Brazil, it´s necessary to understand better the population, and this way the authors can identify factors that influence this fear as well as propose public health policies to treat it.

Objective: The main goal was to compare the prevalence of fear of childbirth between the groups of low-risk pregnancy and gestational diabetes mellitus.

Material and methods: In this cohort study, the sample consisted of 319 patients divided into low-risk pregnancy group (n = 152) and gestational diabetes mellitus group (n = 167). Patients have undergone a semi-structured interview with epidemiological, obstetric, and anthropometric data and the main cause of fear of childbirth. In addition, the patients have marked an "X" on the scale into the Fear of Birth Scale to describe their fear. After delivery, data have been collected through electronic medical records.

Results: The prevalence of fear of childbirth found was higher for the gestational diabetes mellitus group (46.05%) compared to the low-risk pregnancy group (34.73%) with a cutoff score ≥ 54. In the whole sample, the main cause of fear of childbirth (score ≥ 60) was the pain of labor and delivery (31.58%).

Conclusions: The prevalence of fear of childbirth in the present study was greater than 30%, highlighting the relevance of implementing this assessment during prenatal care.

Objectives: To analyze the clinical significance of Toll-Like Receptor 7/Interleukin-23/Interleukin-17 (TLR7/IL-23/IL-17) signaling pathway in patients with Acute Respiratory Distress Syndrome (ARDS).

Method: The clinical data of 85 patients with ARDS were retrospectively analyzed and set as the ARDS group, and the clinical data of 85 healthy participants during the same period were set as the healthy control group. Univariate and multivariate logistic regression were used to analyze risk the factors affecting the prognosis of ARDS patients.

Results: TheTLR7 mRNA expression and IL-23 and IL-17 levels in peripheral blood mononuclear cells were higher in the ARDS group than in the control group (p < 0.05). TLR7 mRNA expression, IL-23, IL-17, Surfactant Protein-D (SP-D), and Clara Cell protein-16 (CC-16) levels were the highest in the severe group, followed by the moderate group, and the lowest in the mild group, while Oxygenation Index (OI) was the lowest in the severe group, followed by the moderate group, and the highest in the mild group (p < 0.05). Multivariate logistic regression analysis found that the disease grade (severe), TLR7 mRNA expression, IL-23 level, and IL-17 level were the risk factors affecting the 28-d survival status of ARDS patients (OR > 1, p < 0.05).

Conclusions: In ARDS patients, the TLR7/IL-23/IL-17 signaling pathway is activated. The expression of this pathway is closely related to the severity of the disease and the levels of lung injury markers, and it is a risk factor that may have a direct impact on the prognosis of ARDS patients.

Objectives: This thesis aims to provide patients with a preventive and therapeutic basis by analyzing IgE level influencing factors of common allergens for Allergic Rhinitis (AR).

Method: Multiple linear regression analysis is made upon questionnaires among 749 cases of AR patients that are divided into 5 age-based groups. Perform serum-specific IgE content testing on patients.

Results: Cockroach being an allergen, AR patients' IgE Level is influenced by allergic history, home-raised plants and animals. For AR patients with mugwort as an allergen, allergy and asthma history could increase IgE level, respectively, β = 4.291 and β = 4.364. If the allergen turns out to be peanut, allergic history would increase the IgE level (β = 0.171), however, the level would be lower in female patients compared with male patients (β = -0.078). For patients with egg as an allergen, allergic history, home-raised plants and animals (pets) would all affect the IgE level, respectively, β = 0.182, β = 0.118 and β = -0.101.

Conclusions: IgE level varies according to allergic history, home-raised plants & animals, gender, furniture renewal, asthma, and ages for patients with different allergens including cockroach, mold, mugwort, peanut, egg and crab. For each kind of allergen, the IgE levels react differently to different influencing factors, thus requiring a thorough analysis of each AR patient's allergen and allergenic factors.

Background: Lower limb coronal alignment was thought to be a predictive factor for Unicompartmental Knee Arthroplasty (UKA) result. The tibial bony resection and implant position lead to joint line change postoperatively. Analysis was done to find out the correlation between these factors.

Methods: From 2019 to 2021, 90 medial Oxford UKA were implanted by a single surgeon. Hip Knee Ankle Angle (HKAA), Lateral Distal Femoral Angle (LDFA), Medial Proximal Tibial Angle (MPTA), and intraoperative bony resection thickness were measured. The medial joint line change was calculated. The correlation between joint line change and alignment change was evaluated.

Results: The mean tibial resection thickness was 4.3 mm. The mean tibial joint line was elevated by 2.3 mm, while the mean femoral joint line proximalized by 0.8 mm. HKAA changed from 8.4° varus preoperatively to 3.6° varus postoperatively. LDFA changed from 89.0° to 86.7°. MPTA changed from 85.6° to 86.6°. Preoperative HKAA showed a strong correlation with postoperative HKAA (p < 0.001), and preoperative MPTA showed a positive correlation with postoperative HKAA (p < 0.001). While preoperative LDFA had a negative correlation with postoperative HKAA (p < 0.001). The femoral joint line change and LDFA change had a significant correlation with HKAA change (p < 0.05).

Conclusion: The change of joint line had no correlation with postoperative HKAA in Oxford UKA. Preoperative HKAA strongly correlated with postoperative HKAA; while preoperative smaller LDFA and larger MPTA had a moderate correlation with postoperative HKAA. The femoral joint line change and LDFA change had a weak to moderate correlation with HKAA change.

Objectives: To determine the prevalence and association of HPV and Herpesviruses in saliva and tissue samples of patients with orofacial tumors.

Methods: Biopsies of tumors were done, and saliva samples were collected from patients with orofacial tumors for the determination of viruses using nested multiplex PCR. Independent variables were sex, age, comorbidities, tumor stage, and length of stay. Outcome variables were the presence or absence of herpesviruses and HPV. Descriptive summaries and inferential statistics were done.

Results: A hundred patients were included in the study. Prevalence of herpesviruses and HPV were 17.6 % and 57.0 % in tumors, and 48.3 % and 60.0 % in the saliva of patients respectively. Herpesviruses detected included EBV (21.3 %), HHV-7 (11.2 %), CMV (6.7 %), HSV-1 (5.1 %), HSV-2 (1.1 %), VZV (1.1 %), and Kaposi sarcoma virus (0.6 %). The most prevalent HPV genotypes were HPV-42 (29 %), HPV-43 (22.7 %), HPV-52 (22.2 %), HPV-39 (18.8 %), and HPV-18 (9.1 %). The odds of EBV being detected in malignant orofacial tumors were 2 times that of benign orofacial tumors. HPV DNA in the saliva of patients with orofacial tumors was 69.7 %, compared to 18.2 % of the control sample (p < 0.001). The median length of stay for all participants was 6.5 days, those associated with viruses stayed longer.

Conclusion: There was a high prevalence of Herpesviruses and HPV in saliva and tumor samples of patients with orofacial tumors, signalling some potential for more work to be done in this area.

Background: With the aim of reducing the risk of Cerebrovascular Accident (CVA) in patients with Non-Valvular Atrial Fibrillation (NVAF), Left Atrial Appendage Occlusion (LAAO) devices are emerging as an alternative to oral anticoagulants.

Objective: To analyze the efficacy and safety of the LAAO procedure in patients with NVAF and contraindications and/or failure for oral anticoagulants.

Method: The search for evidence was carried out in the electronic databases Medline and Embase till January 2024. Additional searches were conducted on Google Scholar. The clinical trials registry database was also consulted. Two blinded investigators performed the search, study selection, and data collection, and assessed quality and risk of bias using the Cochrane tool for randomized clinical trials. Meta-analyses of eligible trials were performed using RevMan 5.4.1 software. The random effects model was used for all analyses.

Results: Five articles were selected, among which three were non-inferiority randomized clinical trials that analyzed the performance and safety of LAAO devices compared to the use of Vitamin K Antagonists (AVKs) or Novel Oral Anticoagulants (NOACs). No randomized clinical trials were found that analyzed populations with absolute contraindications to oral anticoagulants. Having as primary outcomes analyzed the occurrence of stroke (ischemic or hemorrhagic), cardiovascular or unexplained death and systemic embolism, the non-inferiority of the LAAO procedure compared to the use of oral anticoagulants was verified.

Conclusions: For patients with an absolute contraindication to anticoagulation and/or failure to use oral anticoagulants, evidence for the use of LAAO devices is scarce.
