Cervical cancer was considered the fourth most common cancer worldwide in 2020. In order to reduce mortality, an early diagnosis of the tumor is required. Currently, this type of cancer occurs mostly in developing countries due to the lack of vaccination and screening against the Human Papillomavirus. Thus, there is an urgent clinical need for new methods aiming at a reliable screening and an early diagnosis of precancerous and cancerous cervical lesions. Vibrational spectroscopy has provided very good results regarding the diagnosis of various tumors, particularly using Fourier transform infrared microspectroscopy, which has proved to be a promising complement to the currently used histopathological methods of cancer diagnosis. This spectroscopic technique was applied to the analysis of cryopreserved human cervical tissue samples, both squamous cell carcinoma (SCC) and non-cancer samples. A dedicated Support Vector Machine classification model was constructed in order to categorize the samples into either normal or malignant and was subsequently validated by cross-validation, with an accuracy higher than 90%.

In 2020, approximately 10 million people died of cancer, rendering this disease the second leading cause of death worldwide. Detecting cancer in its early stages is paramount for patients' prognosis and survival. Hence, the scientific and medical communities are engaged in improving both therapeutic strategies and diagnostic methodologies, beyond prevention. Optical vibrational spectroscopy has been shown to be an ideal diagnostic method for early cancer diagnosis and surgical margins assessment, as a complement to histopathological analysis. Being highly sensitive, non-invasive and capable of real-time molecular imaging, Raman and Fourier transform infrared (FTIR) spectroscopies give information on the biochemical profile of the tissue under analysis, detecting the metabolic differences between healthy and cancerous portions of the same sample. This constitutes tremendous progress in the field, since the cancer-prompted morphological alterations often occur after the biochemical imbalances in the oncogenic process. Therefore, the early cancer-associated metabolic changes are unnoticed by the histopathologist. Additionally, Raman and FTIR spectroscopies significantly reduce the subjectivity linked to cancer diagnosis. This review focuses on breast and head and neck cancers, their clinical needs and the progress made to date using vibrational spectroscopy as a diagnostic technique prior to surgical intervention and intraoperative margin assessment.

Objective: To describe the implementation of a rapid response team in a large nonprofit hospital, indicating relevant issues for other initiatives in similar contexts, particularly in Latin America., Methods: In general terms, the intervention consisted of three major components: (1) a tool to detect aggravation of clinical conditions in general wards; (2) the structuring of a rapid response team to attend to all patients at risk; and (3) the monitoring of indicators regarding the intervention. This work employed four half-year Plan-Do-Study-Act cycles to test and adjust the intervention from January 2013 to December 2014., Results: Between 2013 and 2014, the rapid response team attended to 2,296 patients. This study showed a nonsignificant reduction in mortality from 8.3% in cycle 1 to 5.0% in cycle 4; however, death rates remained stable in cycles 3 and 4, with frequencies of 5.2% and 5.0%, respectively. Regarding patient flow and continuum of critical care, which is a premise of the rapid response system, there was a reduction in waiting time for intensive care unit beds with a decrease from 45.9% to 19.0% in the frequency of inpatients who could not be admitted immediately after indication (p < 0.001), representing improved patient flow in the hospital. In addition, an increase in the recognition of palliative care patients from 2.8% to 10.3% was noted (p = 0.005)., Conclusion: Implementing a rapid response team in contexts where there are structural restrictions, such as lack of intensive care unit beds, may be very beneficial, but a strategy of adjustment is needed.

Time for delivery and delivery pathway in twin pregnancies are still in great debate. Our study goal was to compare the characteristics of delivery and maternal-foetal outcome in uncomplicated near-term twin pregnancies undergoing labour induction and those with spontaneous labour. We found no statistical differences in patients with twin pregnancies who underwent labour induction and those with spontaneous labour regarding the history of previous caesarean delivery, parity, pregnancy achieved by assisted reproductive techniques (ART), chorionicity and cervical dilation at the admission as well as maternal and neonatal morbidity, and admission to the neonatal intensive care unit. There were significant differences in the caesarean section rate (60.6 vs. 33.3%, p < .05) and the time interval between delivery of the first and second foetus (9.8 vs. 11.7 min, p = .024). There was an increased incidence of caesarean section after the induction of labour. However, it appears to be a safe option.

Body stalk anomaly is a rare malformation. This anomaly in monozygotic twins is extremely unusual. We describe a case of monoamniotic pregnancy discordant for body stalk anomaly diagnosed at 11 weeks. Ultrasound showed a fetus with a large anterior abdominal wall defect, anomaly of the spine and no evidence of lower extremities and other with a normal morphology. As far as our concern, only three monoamniotic pregnancies discordant for this malformation were reported. Our case represents the fourth reported monoamniotic pregnancy discordant for body stalk anomaly with diagnosis made by ultrasound and the second diagnosed in the first trimester.

Purpose of Investigation: To characterize the risk factors for abnormal cervical cytology among women with human immunodeticiency virus (HIV), and to determine the relationship between antiretroviral therapy (ART) and cytology results., Materials and Methods: Retrospective study of clinical data of 115 HIV-infected women between January 2008 and December 2011. Analysis of cervical smears history, as well as, epidemiologic, medical, and sexual factors, administration of ART, CD4 cells count, and HIV viral load were performed., Results: Mean age was 35.9 ± 6.5 years. Average time of HIV infection was 10.5 ± 4.5 years. HPV infection prevalence was 37.4%, the majority was high-risk. An abnormal Papanicolaou smear was found in 43.5%. Atypical squamous cell of undetermined significance (ASC-US) was reported in 7.8%, low-grade squamous intraepithelial lesions (LSIL) in 32.2%, and high-grade squamous intraepithelial lesions (HSIL) in 3.5%. HPV infection was the only statistical predictor of abnormal cytology (p < 0.001; OR = 0.042). ART, CD4 cells count, and HIV viral load did not correlate to regression of abnormal cytology., Conclusion: These women should be followed-up according to current cervical cancer screening guidelines, independently of the therapy, CD4 cells count, and HIV viral load.
