Development of a Prognostic Model for Early Breast Cancer Integrating Neutrophil to Lymphocyte Ratio and Clinical-Pathological Characteristics.

BACKGROUND: Breast cancer-related inflammation is critical in tumorigenesis, cancer progression, and patient prognosis. Several inflammatory markers derived from peripheral blood cells count, such as the neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), monocyte-lymphocyte ratio (MLR), and systemic immune-inflammation index (SII) are considered as prognostic markers in several types of malignancy. METHODS: We investigate and validate a prognostic model in early patients with breast cancer to predict disease-free survival (DFS) based on readily available baseline clinicopathological prognostic factors and preoperative peripheral blood-derived indexes. RESULTS: We analyzed a training cohort of 710 patients and 2 external validation cohorts of 980 and 157 patients with breast cancer, respectively, with different demographic origins. An elevated preoperative NLR is a better DFS predictor than others scores. The prognostic model generated in this study was able to classify patients into 3 groups with different risks of relapse based on ECOG-PS, presence of comorbidities, T and N stage, PgR status, and NLR. CONCLUSION: Prognostic models derived from the combination of clinicopathological features and peripheral blood indices, such as NLR, represent attractive markers mainly because they are easily detectable and applicable in daily clinical practice. More comprehensive prospective studies are needed to unveil their actual effectiveness.

Human Papillomavirus 16 Lineage A Variants Associated With Persistent Genital Infections in Men: The HPV Infection in Men (HIM) Study.

BACKGROUND: Human papillomavirus (HPV) 16 non-A lineage variants have higher carcinogenic potential for cervical cancer. HPV-16 variants natural history among males is not established. We evaluated HPV-16 variants prevalence and persistence in the external genitalia of men enrolled in the prospective HPV Infection in Men (HIM) Study. METHODS: The HIM Study included men from the United States, Brazil, and Mexico. HPV-16 variants were distinguished using polymerase chain reaction sequencing. The prevalence of HPV-16 variants was assessed, and associations with infection persistence were estimated. RESULTS: We characterized the HPV-16 variants for 1700 genital swab samples from 753 men and 22 external genital lesions in 17 men. The prevalence of HPV-16 lineages differed by country and marital status (P < .001). Overall, 90.9% of participants harbored lineage A variants. The prevalence of non-A lineages was heterogenous among countries. HPV-16 lineage A variants were associated with a 2.69-fold increased risk of long-term persistent infections compared with non-A lineages. All high-grade penile intraepithelial neoplasia harbored lineage A variants and occurred in the context of long-term persistent infections with the same variants. CONCLUSIONS: The prevalence and persistence of HPV-16 variants observed at the male external genitalia suggest differences in the natural history of these variants between men and women, which may be associated with intrinsic differences in the infected genital epithelia.

Risk factors for head and neck cancer in more and less developed countries: Analysis from the INHANCE consortium.

OBJECTIVE: We analyzed the pooled case-control data from the International Head and Neck Cancer Epidemiology (INHANCE) consortium to compare cigarette smoking and alcohol consumption risk factors for head and neck cancer between less developed and more developed countries. SUBJECTS AND METHODS: The location of each study was categorized as either a less developed or more developed country. We compared the risk of overall head and neck cancer and cancer of specific anatomic subsites associated with cigarette smoking and alcohol consumption. Additionally, age and sex distribution between categories was compared. RESULTS: The odds ratios for head and neck cancer sites associated with smoking duration differed between less developed and more developed countries. Smoking greater than 20 years conferred a higher risk for oral cavity and laryngeal cancer in more developed countries, whereas the risk was greater for oropharynx and hypopharynx cancer in less developed countries. Alcohol consumed for more than 20 years conferred a higher risk for oropharynx, hypopharynx, and larynx cancer in less developed countries. The proportion of cases that were young (<45 years) or female differed by country type for some HNC subsites. CONCLUSION: These findings suggest the degree of industrialization and economic development affects the relationship between smoking and alcohol with head and neck cancer.

Oncological Surgery During the COVID-19 Pandemic: Effectiveness of Preoperative Screening and Factors Associated with Postoperative SARS-CoV-2 Infection.

BACKGROUND: Routine preoperative screening of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) with reverse transcriptase-polymerase chain reaction (RT-PCR) may reduce in-hospital SARS-CoV-2 transmission. METHODS: This was a prospective, observational, cohort study. The endpoints were the incidence of asymptomatic patients with positive preoperative RT-PCR results and the incidence and factors associated with postoperative SARS-CoV-2 infection in patients with cancer referred for elective surgery. Patients with elective surgery between May and October 2020 were included. RT-PCR of nasopharyngeal swabs was performed preoperatively for all patients. Postoperative SARS-CoV-2 infection was assessed within 30 postoperative days. RESULTS: A total of 1636 preoperative screening RT-PCR tests were performed. Of these, 102 (6.2%) cases were positive, and 1,298 surgical procedures were analyzed. The postoperative SARS-CoV-2 infection rate was 0.9%. The length of stay (odds ratio [OR] 1.08; 95% confidence interval [CI] 1.04-1.11; p < 0.001), surgical time (OR 1.004; 95% CI 1.001-1.008; p = 0.023), intensive care unit admission (OR 7.7; 95% CI 2.03-29.28; p = 0.003), and hospital readmissions (OR 9.56; 95% CI 2.50-36.56; p = 0.001) were associated with postoperative coronavirus disease (COVID-19). Using unadjusted and adjusted logistic regression, length of stay (OR 1.08; 95% CI 1.04-1.11; p < 0.001), and readmission (OR 9.02; 95% CI 2.30-35.48; p = 0.002) were independent factors of postoperative COVID-19. CONCLUSIONS: Screening patients preoperatively may reduce in-hospital SARS-CoV-2 transmission. Length of stay and readmission were independently correlated with postoperative COVID-19.

Prognostic Impact of Pathology, Cytoreduction, and Tumor Markers in Pseudomyxoma Peritonei.

INTRODUCTION: The pathologic classification of pseudomyxoma peritonei is controversial. This study aimed to standardize the histopathological evaluation of pseudomyxoma peritonei and identify the clinicopathological factors associated with survival. METHODS: A pathologic review was performed to systematize the pathology report and verify the relationship between clinical features and survival. Terminology was based on the World Health Organization and Peritoneal Surface Oncology Group International definitions. Preoperative serum levels of carcinoembryonic antigen, CA19-9, and CA-125 were evaluated to determine their association with overall survival (OS) and ability to predict CC0-1 cytoreduction. RESULTS: Among 109 patients with carcinomas resulting from primary appendiceal neoplasms, 72 had pseudomyxoma peritonei of appendiceal origin and underwent debulking surgery. CC0-1 cytoreduction and CC2-3 cytoreduction were achieved in 61% and 39% of patients, respectively. Patients in the CC0-1 and CC2-3 groups had an OS of 122.80 and 32.92 mo, respectively. The histologic grade was associated with CC0-1 cytoreduction; however, it did not influence OS. Patients with CC0-1 cytoreduction, acellular mucin, and low-grade lesions had better disease-free survival. Higher preoperative CA19-9 levels were associated with poor OS. Normal carcinoembryonic antigen values were associated with 100% sensitivity for predicting CC0-1. CA19-9 levels of 625 U/mL were associated with a low possibility of predicting CC0-1. CONCLUSIONS: Histologic grades are associated with disease-free survival when CC0-1 cytoreduction is achieved. Normal preoperative CA19-9 levels were associated with a better OS. CC0-1 cytoreduction is the main determinant of longer survival.

Prevalence of human papillomavirus 6 and 11 variants in recurrent respiratory papillomatosis.

Human papillomavirus (HPV) types 6 and 11 are the etiological agents of recurrent respiratory papillomatosis (RRP). We examined the prevalence and distribution of HPVs 6 and 11 genetic variants in juvenile onset (JORRP) and adult onset (AORRP) laryngeal papillomas. Cases of JORRP and AORRP were collected, retrospectively. HPV detection and genotyping were accessed by polymerase chain reaction-sequencing in 67 RRP samples. Overall, the most prevalent HPV-6 variants were from B1 (55.8%) and B3 (27.9%) sublineages, whereas among HPV-11 positive samples A2 (62.5%) variants were predominant. A higher prevalence of HPV-6 B1 was observed in JORRP (83.3% B1 and 16.7% B3), compared with AORRP cases (58.3% B1 and 41.7% B3). HPV-11 A2 variants were more prevalent both in JORRP (57.2%) and in AORRP cases (70.0%). Nevertheless, with the exception that HPV-6 B1 were significantly less likely to recur, there was a lack of association between any particular HPVs 6 or 11 variant and clinicopathological features. Our data do not support an association between HPVs 6 and 11 variability and RRP.

COVID-19 outbreak in Brazil: adherence to national preventive measures and impact on people's lives, an online survey.

BACKGROUND: The first case of COVID-19 infection was diagnosed in Brazil 26th February 2020. By March 16th, physical distancing and confinement measures were implemented by the Brazilian government. Little is known about how these measures were followed up by the Brazilian people and their impact on daily routine. METHODS: In early April 2020, using an online platform, we organized an online survey among adults living in Brazil about their COVID-19 preventive behavior and impact on their daily routine. RESULTS: Data from 23,896 respondents were analyzed (mean age: 47.4 years). Due to COVID-19 restrictions, half (51.1%) of the professionals reported working from home. Regular handwashing was practiced by 98.7% of participants; 92.6% reported adhering to the 1.5-2 m physical distancing rule, but only 45.5% wore a face mask when going outside. While 29.3% of respondents found it relatively easy to stay at home, indoor confinement was extremely difficult for 7.9% of participants. Moreover, 11% of participants were extremely worried about their health during the COVID-19 epidemic. Younger people, male, persons living in a rural area/village or popular neighbourhoods, students and workers reported less preventive behaviour. CONCLUSION: Restrictive measures markedly affected the daily and professional routines of Brazilians. Participants showed a satisfactory level of adherence to national COVID-19 prevention guidelines. Qualitative and follow-up studies are needed to monitor the impact of COVID-19 in the Brazilian society.

Role of systematic pelvic and para-aortic lymphadenectomy in delayed debulking surgery after six neoadjuvant chemotherapy cycles for high-grade serous ovarian carcinoma.

INTRODUCTION: We analyzed the role of systematic pelvic and para-aortic lymphadenectomy in delayed debulking surgery after six neoadjuvant chemotherapy (NACT) cycles for advanced high-grade serous ovarian carcinoma. MATERIALS AND METHODS: We retrospectively reviewed patients with advanced ovarian carcinoma who underwent NACT with carboplatin-paclitaxel between 2008 and 2016. Patients were included only if they had FIGO IIIC-IVB high-grade serous carcinoma with clinically negative lymph nodes after six NACT cycles (carboplatin-paclitaxel) and underwent complete or near complete cytoreduction. Patients with partial lymphadenectomy or bulky nodes were excluded. Patients who underwent systematic pelvic and aortic lymphadenectomy and those who did not undergo lymph node dissection were compared. Progression-free and overall survivals were analyzed using the Kaplan-Meier method. RESULTS: Totally, 132 patients with FIGO IIIC-IVB epithelial ovarian carcinoma were surgically treated after NACT. Sixty patients were included (39 and 21 in the lymphadenectomy and nonlymphadenectomy group, respectively); 40% had suspicious lymph nodes before NACT. Patient characteristics, blood transfusion numbers, and complication incidence were similar between the groups. In the lymphadenectomy group, 12 patients (30.8%) had histologically positive lymph nodes and the surgical time was longer (229 vs. 164 min). The median overall survival in the lymphadenectomy and nonlymphadenectomy groups, respectively, was 56.7 (95% CI 43.4-70.1) and 61.2 (21.4-101.0) months (p = 0.934); the corresponding disease-free survival was 8.1 (6.2-10.1) and 8.3 (5.1-11.6) months (p = 0.878). Six patients exclusively presented with lymph node recurrence. CONCLUSIONS: Systematic lymphadenectomy after six NACT cycles may have no influence on survival.

Mutational Profiling of Driver Tumor Suppressor and Oncogenic Genes in Brazilian Malignant Pleural Mesotheliomas.

BACKGROUND: Malignant pleural mesothelioma (MPM) is a highly lethal disease comprising a heterogeneous group of tumors with challenging to predict biological behavior. The diagnosis is complex, and the histologic classification includes 2 major subtypes of MPM: epithelioid (∼60% of cases) and sarcomatous (∼20%). Its identification depends upon pathological investigation supported by clinical and radiological evidence and more recently ancillary molecular testing. Treatment options are currently limited, with no known targeted therapies available. OBJECTIVES: To elucidate the mutation profile of driver tumor suppressor and oncogenic genes in a cohort of Brazilian patients. METHODS: We sequenced 16 driver genes in a series of 43 Brazilian malignant mesothelioma (MM) patients from 3 distinct Brazilian centers. Genomic DNA was extracted from formalin-fixed paraffin-embedded tumor tissue blocks, and the TERT promoter region was amplified by PCR followed by direct capillary sequencing. The Illumina TruSight Tumor 15 was used to evaluate 250 amplicons from 15 genes associated with solid tumors (AKT1, GNA11, NRAS, BRAF, GNAQ, PDGFRA, EGFR, KIT, PIK3CA, ERBB2, KRAS, RET, FOXL2, MET,and TP53). Library preparation with the TruSight Tumor 15 was performed before sequencing at the MiSeq platform. Data analysis was performed using Sophia DDM software. RESULTS: Out of 43 MPM patients, 38 (88.4%) were epithelioid subtype and 5 (11.6%) were sarcomatoid histotype. Asbestos exposure was present in 15 (39.5%) patients with epithelioid MPM and 3 (60%) patients with sarcomatoid MPM. We found a TERT promoter mutation in 11.6% of MM, and the c.-146C>T mutation was the most common event. The next-generation sequencing was successful in 33 cases. A total of 18 samples showed at least 1 pathogenic, with a median of 1.8 variants, ranging from 1 to 6. The most mutated genes were TP53 and ERBB2 with 7 variants each, followed by NRAS BRAF, PI3KCA, EGFR and PDGFRA with 2 variants each. KIT, AKT1, and FOXL2 genes exhibited 1 variant each. Interestingly, 2 variants observed in the PDGFRA gene are classic imatinib-sensitive therapy. CONCLUSIONS: We concluded that Brazilian MPM harbor mutation in classic tumor suppressor and oncogenic genes, which might help in the guidance of personalized treatment of MPM.

Evaluation of Parotid Salivary Gland Echo Texture by Ultrasound Examinations and Correlation With Whole-Body Scintigraphy After Radioiodine Therapy in Patients With Differentiated Thyroid Carcinoma.

OBJECTIVES: This study aimed to evaluate the echo texture of the parotid salivary glands before and after radioiodine therapy (RIT) using ultrasound (US) images in patients with differentiated thyroid cancer and to evaluate the correlations between post-RIT whole-body scintigraphy (WBS) images and US image patterns in salivary and cervical areas. METHODS: A retrospective study was performed with data on demographic and clinical information, US examinations, and WBS images collected through medical recordings. RESULTS: Comparing the US features before and after RIT, significant echo texture heterogeneity was found in 31.3% of all patients evaluated. When evaluated according to the level of iodine 131 (I-131) radioactivity (<5.6, 5.6-<9.3, and ≥9.3 GBq), echo texture heterogeneity was significantly associated with the 5.6-GBq I-131 radioactivity group (P < .001). No association was found for any level of I-131 post-RIT WBS uptake intensity and changes in US feature patterns. CONCLUSIONS: Ultrasound may be a useful tool for evaluating chronic sialadenitis after RIT, and the I-131 uptake intensity using a routine post-RIT WBS is not associated with US echo texture changes.

The impact of the time to start radiation therapy on overall survival in newly diagnosed glioblastoma.

PURPOSE: The standard treatment for newly diagnosed glioblastoma includes maximal safe surgical resection followed by concurrent radiation therapy and temozolomide (TMZ) and maintenance TMZ. The impact of time to start radiation therapy (TRT) on overall survival (OS) in glioblastoma patients is controversial. The study aimed to evaluate the impact of TRT on OS in patients diagnosed with glioblastoma who received standard treatment. METHODS: In this retrospective study, we included patients with confirmed diagnosis of glioblastoma treated from 2011 to 2016. TRT was defined as the time between surgery (biopsy or resection) and the first day of radiation therapy. The endpoint was OS. The patients were divided according to the TRT in three categories: < 30 days, 30-60 days and ≥ 60 days. RESULTS: A total of 134 patients were included with a mean age of 51.82 years (range 19-78 years). Median TRT was 80 days. On univariate and multivariable analysis, we identified age as the only significant independent predictor for OS. There was no statistically significant negative impact of TRT on OS (p = 0.47). CONCLUSIONS: There was no clear evidence that delaying post-operative combined chemoradiotherapy negatively impacts OS, not even for TRT longer than 60 days.

Return to work after breast cancer diagnosis: An observational prospective study in Brazil.

BACKGROUND: In North America and Europe, return-to-work (RTW) rates vary among breast cancer (BC) survivors, from 24% to 66% and from 53% to 82% at 6 and 36 months after diagnosis, respectively. To date, there is a lack of data on RTW rates after BC diagnosis in Latin America. Therefore, the primary objectives of this study were to define RTW rates at 12 and 24 months after BC diagnosis and to identify the factors associated with RTW in this population. METHODS: In total, 125 employed women from a single institution with newly diagnosed BC were interviewed by telephone at 6, 12, and 24 months after diagnosis. Those who had inoperable or metastatic disease were excluded. RESULTS: Overall, RTW rates were 30.3% and 60.4% at 12 and 24 months after BC diagnosis, respectively. Most women reported that they received support from their employer, but only 29.1% reported having been offered work adjustments. In multivariate analysis, the factors associated with positive RTW outcomes included higher household income (odds ratio [OR], 17.76; 95% confidence interval [CI], 3.33-94.75; P = .001), breast-conserving surgery (OR, 9.77; 95% CI, 2.03-47.05; P = .004), and work adjustments (OR, 37.62; 95% CI, 2.03-47.05; P = .004). The factors associated with negative RTW outcomes included adjuvant endocrine therapy (OR, 0.11; 95% CI, 0.02-0.74; P = .023), and depression diagnosed after BC (OR, 0.07; 95% CI, 0.01-0.63; P = .017). CONCLUSIONS: RTW rates in the current study were lower than those observed in developed countries but similar to the rates among low-income Americans. Workplace adjustments, higher income, breast-conserving surgery, endocrine therapy, and depression after BC played an important role in the RTW decision.

Chemoradiotherapy versus chemotherapy as adjuvant treatment for localized gastric cancer: a propensity score-matched analysis.

BACKGROUND: Treatment of localized gastric cancer (LGC) consists of surgical resection followed by adjuvant treatment. Both chemoradiation (CRT) and chemotherapy (CT) regimens have shown benefit in survival outcomes versus observation. However, there are few data comparing these approaches. METHODS: This study included consecutive patients with LGC treated at Instituto do Cancer do Estado de Sao Paulo (ICESP) from 2012 to 2015. CRT was based on the INT-0116 regimen and CT consisted of a platinum and fluoropyrimidine doublet. Treatment choice was based on physician preference. Toxicity was evaluated for every cycle. Overall survival (OS) analysis was performed by Kaplan-Meier. A propensity score-matched analysis was performed to minimize selection bias. RESULTS: A total of 309 patients were evaluated, 227 in CRT group and 82 in CT group. The most prevalent grade 3/4 toxicities in CRT and CT groups were: nausea/vomiting (9.25 vs 4.9%), fatigue (9.3% vs 2.4%), mucositis (4.4% vs 1.2%), neutropenia (37.8% vs 20.9%), febrile neutropenia (3.9% vs 0%), anemia (4.3% vs 6.1%), thrombocytopenia (2.6% vs 4.9%), neuropathy (0 vs 2.4%) and hand-foot syndrome (0.4% vs 2.4%). Two grade 5 toxicities (febrile neutropenia and anemia) occurred in CRT group. There was no difference in the pattern of recurrence. After a median follow-up of 23.5 months (CRT) and 20.6 months (CT), there was no difference in OS between groups. CONCLUSIONS: CT and CRT present similar efficacy and tolerability as adjuvant treatment for LGC.

Co-infection of sexually transmitted pathogens and Human Papillomavirus in cervical samples of women of Brazil.

BACKGROUND: Some sexually transmitted infectious agents, such as Chlamydia trachomatis and Herpes simplex, cause local inflammation, and could contribute to Human Papillomavirus (HPV) and cervical lesion progression. Thus, the aim of this study was to determine any association between the presence of microorganisms of gynecological importance, sexual behavior, clinical and demographical variables to the development and progress of cervical lesions. METHODS: One hundred and thirty-two women between 14 and 78 years and living at Vitória da Conquista, Bahia, Brazil, were included (62 individuals with cervical lesions and 70 without lesions). They answered a questionnaire to provide data for a socioeconomic and sexual activity profile. Samples of cervical swabs were collected and analyzed by PCR to detect genital microorganisms and HPV. Quantitative PCR was used to detect and quantify Ureaplasma urealyticum and Ureaplasma parvum. Univariate and multiple logistic regression were performed to measure the association with the cervical lesions, and an odds ratio (OR) with 95% confidence intervals (95%CI) were calculated. The Mann-Whitney U test was also used to compare the microorganism load in the case and control groups. The significance level was 5% in all hypotheses tested. RESULTS: Cervical lesions were associated with: women in a stable sexual relationship (OR = 14.21, 95%CI = 3.67-55.018), positive PCR for HPV (OR = 16.81, 95%CI = 4.19-67.42), Trichomonas vaginalis (OR = 8.566, 95%CI = 2.04-35.94) and Gardnerella vaginalis (OR = 6.13, 95%CI = 1.53-24.61), adjusted by age and qPCR for U. parvum. U. parvum load showed a statistical difference between the case and control groups (p-value = 0.002). CONCLUSION: Variables such as stable relationship, HPV, T. vaginalis, G. vaginalis were associated with cervical lesions in epidemiological studies. U. parvum load was higher in woman with cervical lesions compared with women without lesions. Additional studies are needed to better understand the role of these factors in cervical lesion development.

Human papillomavirus (HPV) 16 and the prognosis of head and neck cancer in a geographical region with a low prevalence of HPV infection.

BACKGROUND: The role of human papillomavirus (HPV) on head and neck squamous cell carcinoma (HNSCC) survival in regions with low HPV prevalence is not yet clear. We evaluated the HPV16 infection on survival of HNSCC Brazilian patient series. METHODS: This cohort comprised 1,093 HNSCC cases recruited from 1998 to 2008 in four Brazilian cities and followed up until June 2009. HPV16 antibodies were analyzed by multiplex Luminex assay. In a subset of 398 fresh frozen or paraffin blocks of HNSCC specimens, we analyzed for HPV16 DNA by L1 generic primer polymerase chain reaction. HNSCC survival according to HPV16 antibodies was evaluated through Kaplan-Meier method and Cox regression. RESULTS: Prevalence of HPV16 E6 and E6/E7 antibodies was higher in oropharyngeal cancer than in other head and neck tumor sites. HPV16 DNA positive in tumor tissue was also higher in the oropharynx. Seropositivity for HPV16 E6 antibodies was correlated with improved HNSCC survival and oropharyngeal cancer. The presence of HPV16 E6/E7 antibodies was correlated with improved HNSCC survival and oropharyngeal cancer survival. The death risk of oropharyngeal squamous cell carcinoma patients HPV16 E6/E7 antibodies positive was 78 % lower than to those who test negative. CONCLUSION: Oropharyngeal squamous cell carcinoma is less aggressive in the HPV16 E6/E7 positive serology patients. HPV16 E6/E7 antibody is a clinically sensible surrogate prognostic marker of oropharyngeal squamous cell carcinoma.

A critical analysis of test-retest reliability in instrument validation studies of cancer patients under palliative care: a systematic review.

BACKGROUND: Patient-reported outcome validation needs to achieve validity and reliability standards. Among reliability analysis parameters, test-retest reliability is an important psychometric property. Retested patients must be in a clinically stable condition. This is particularly problematic in palliative care (PC) settings because advanced cancer patients are prone to a faster rate of clinical deterioration. The aim of this study was to evaluate the methods by which multi-symptom and health-related qualities of life (HRQoL) based on patient-reported outcomes (PROs) have been validated in oncological PC settings with regards to test-retest reliability. METHODS: A systematic search of PubMed (1966 to June 2013), EMBASE (1980 to June 2013), PsychInfo (1806 to June 2013), CINAHL (1980 to June 2013), and SCIELO (1998 to June 2013), and specific PRO databases was performed. Studies were included if they described a set of validation studies. Studies were included if they described a set of validation studies for an instrument developed to measure multi-symptom or multidimensional HRQoL in advanced cancer patients under PC. The COSMIN checklist was used to rate the methodological quality of the study designs. RESULTS: We identified 89 validation studies from 746 potentially relevant articles. From those 89 articles, 31 measured test-retest reliability and were included in this review. Upon critical analysis of the overall quality of the criteria used to determine the test-retest reliability, 6 (19.4%), 17 (54.8%), and 8 (25.8%) of these articles were rated as good, fair, or poor, respectively, and no article was classified as excellent. Multi-symptom instruments were retested over a shortened interval when compared to the HRQoL instruments (median values 24 hours and 168 hours, respectively; p = 0.001). Validation studies that included objective confirmation of clinical stability in their design yielded better results for the test-retest analysis with regard to both pain and global HRQoL scores (p < 0.05). The quality of the statistical analysis and its description were of great concern. CONCLUSION: Test-retest reliability has been infrequently and poorly evaluated. The confirmation of clinical stability was an important factor in our analysis, and we suggest that special attention be focused on clinical stability when designing a PRO validation study that includes advanced cancer patients under PC.

Factors Related to the Sleep Duration of 3-Month-Old Infants.

Objective To identify the factors related to sleep duration in 3-month-old infants. Materials and Methods From 2021 to 2023, we conducted a cross-sectional study in the city of Araraquara, Brazil, involving 140 mothers and their respective 3-month-old infants. Maternal socioeconomic, demographic, obstetric, and nutritional characteristics, as well as nutritional and morbidity characteristics of the respective infants, were evaluated. Sleep duration was determined by the Brief Infant Sleep Questionnaire (BISQ). Multivariate linear regression analysis was used to assess the associations of maternal, newborn, and infant factors with sleep duration at three months. Results The nighttime sleep duration of the infants was of 9 hours. There were negative associations between nighttime sleep duration and prone sleep position ( p = 0.011), falling asleep between 8:30 pm and 11:00 pm ( p = 0.032), falling asleep after 11:00 pm ( p < 0.001), respiratory infection ( p = 0.011), dermatitis ( p = 0.002), and the presence of children under 9 years of age in the household ( p = 0.013). Discussion In the present study, factors such as infant morbidity, the presence of other children in the household, and sleeping habits were associated with a decrease in sleep duration in 3-month-old infants. Therefore, we emphasize the importance of early diagnosis of morbidity in the first months of life and of promoting healthy habits such as regulating the time to go to sleep, providing an adequate sleep environment, and other practices that help improve the quality and duration of sleep.

Factors associated with domestic violence in pregnant women during the COVID-19 pandemic: Araraquara Cohort study.

AIMS AND METHOD: This cross-sectional study, carried out from 2021 to 2022, investigated the factors associated with domestic violence in 400 Brazilian pregnant women during the COVID-19 pandemic. Violence was assessed with the World Health Organization's Violence Against Women questionnaire and the Abuse Assessment Screen. Demographic, socioeconomic, obstetric, lifestyle and mental health data were collected. RESULTS: Violence at any time in their lives was reported by 52.2% of the women, and psychological violence was the most prevalent type (19.5%). Violence was associated with being single and mental health changes. Pregnant women exposed to any lifetime violence and psychological violence were, respectively, 4.67 and 5.93 times more likely to show mental health changes compared with women with no reported violence. CLINICAL IMPLICATIONS: Training health professionals involved in prenatal care in the early detection of single women and women with mental health changes could be important in preventing domestic violence.

Prognostic value of Maspin protein level in patients with triple negative breast cancer.

The search for prognostic markers in breast cancer has bumped into a typical feature of these tumors, intra and intertumoral heterogeneity. Changes in the expression profile, localization of these proteins or shedding to the surrounding stroma can be useful in the search for new markers. In this context, classification by molecular subtypes can bring perspectives for both diagnosis and screening for appropriate treatments. However, the Triple Negative (TN) subtype, which is already the one with the worst prognosis, lacks appropriate and consistent molecular markers. In this work, we analyzed 346 human breast cancer samples in tissue microarrays (TMA) from cases diagnosed with invasive breast carcinoma to assess the expression and localization pattern of Maspin and their correlation with clinical parameters. To complement our findings, we also used TCGA data to analyze the mRNA levels of these respective genes. Our data suggests that the TN subtype demonstrates a higher level of cytoplasmic Maspin compared to the other subtypes. Maspin transcript levels follow the same trend. However, TN patients with lower Maspin expression tend to have worse overall survival and free-survival metastasis rates. Finally, we used Maspin expression data to verify possible relationships with the clinicopathological information of our cohort. Our univariate analyses indicate that Maspin is related to the expression of estrogen receptor (ER) and progesterone receptor (PR). Furthermore, Maspin expression levels also showed correlation with Scarff-Bloom-Richardson (SBR) parameter, and stromal Maspin showed a relationship with lymph node involvement. Our data is not consistently robust enough to categorize Maspin as a prognostic marker. However, it does indicate a change in the expression profile within the TN subtype.
