One of the main reasons is nipple soreness, which contributes greatly to early cessation of breastfeeding. A soreness evaluation through validated scales, performed by health care professionals during the first few days, can contribute to improve breastfeeding and support for the mothers. Research Aim Knowing the prevalence of nipple soreness during breastfeeding at 48 hours postpartum at the Infanta Cristina University Hospital (Madrid, Spain) through a cross-sectional descriptive study. Materials and Methods The study took place between February and March 2019. A survey of 58 postpartum second day mothers was conducted including the Visual Analogue Scale (VAS) and Lactation Assessment Scale (LATCH) score for breastfeeding assessment. A descriptive analysis of secondary variables and subsequent bivariate inferential was performed for 95% confidence interval (CI). Results The prevalence of nipple soreness observed is 97% (95% CI = 92-100%). It was found, significantly (p = 0.001), that the higher the score on LATCH, the lower the score on VAS and therefore the less pain. We found a relationship between women who were in skin-to-skin contact with their babies for 2 hours without interruption after birth and a higher pain score (p = 0.046). No other associations were found between VAS and other variables such as parity, type of birth, artificial milk supplements for the newborn, or using a pacifier. Conclusions The high percentage of nipple soreness detected highlights that breastfeeding can be unpleasant in the first days after delivery. It is important to include in clinical practice the assessment of nipple soreness and the effectiveness of breastfeeding using validated scales.

Adoption of prognostic molecular assays for prostate cancer requires evidence of robust performance in different racial groups. Retrospective analysis was conducted to assess the performance of the Oncotype DX

Genomic Prostate Score

test in African American and Caucasian American men with surgically treated prostate cancer.

We compared the assay results (scale 0-100) and the 4 gene group scores in biopsy specimens from 201 African American and 1,144 Caucasian American men with clinically localized prostate cancer in 6 cohorts. Adverse pathology was defined as high grade (primary Gleason pattern 4 or any pattern 5) and/or nonorgan-confined disease (≥pT3). Binary logistic regression models were used for adverse pathology. Biochemical recurrence was defined as 2 successive prostate specific antigen levels >0.2 ng/ml or initiation of salvage therapy after radical prostatectomy. Cox proportional hazards models evaluated the association of the assay result or racial group with time to biochemical recurrence.

Each cohort had different clinical risk distributions and percentages of African Americans, although median and interquartile ranges of the assay results and gene group scores were similar between both racial groups. In a multivariable model with the assay and pathological/clinical features including race, the assay was significantly associated with adverse pathology (p ≤0.004) and biochemical recurrence (p <0.001). Race was not a significant predictor of either end point.

The assay is similarly predictive of outcomes in African American and Caucasian American patients, and improves risk stratification in men with newly diagnosed prostate cancer from both racial groups.

However, the amorphous state is inherently unstable toward recrystallization. Coamorphous systems of a drug and a small-molecule excipient or of two complementary drugs often show an enhanced stability. Diabetes and hypertension are frequently coexistent. In this paper a study on the coamorphization of the poorly water-soluble antidiabetic drug gliclazide (glz) and the antihypertensive drug valsartan (val) is reported. Amorphous glz recrystallized after 1 d under ambient conditions, whereas coamorphous glz-val containing glz and val in a 11 or 12 molar ratio was stable for at least four months at 20 °C and 56% relative humidity. The dissolution rate of glz increased in the order crystalline glz  less then  glz-val_11  less then  glz-val_12. Furthermore, ternary coamorphous systems of glz, val and an excipient were prepared; glz-val_11_PVP, glz-val_11_HPC, glz-val_11_ALM, glz-val_11_MCC (PVP = polyvinylpyrrolidone, HPC = hydroxypropyl cellulose, ALM = α-lactose monohydrate, MCC = microcrystalline cellulose). MCC and HPC did not affect the stability of the coamorphous system, while ALM promoted the recrystallization of glz in glz-val_11_ALM during storage and freshly prepared glz-val_11_PVP contained small amounts of crystalline glz. Glz-val_11_MCC showed enhanced dissolution properties compared to crystalline glz and glz-val_11 and is a viable fixed-dose formulation.In critically examining literature on electrohypersensitivity and the reported somatic responses to anthropogenic modulated radiofrequency radiation (RFR) exposure, it becomes apparent that electrohypersensitivity is one part of a range of consequences. Current evidence on the necessity of considering patients' overall health status leads us to propose a new model in which electrohypersensitivity is but part of the electrosensitive status inherent in being human. We propose the likelihood and type of response to environmental RFR include i) a linear somatic awareness continuum, ii) a non-linear somatic response continuum, and iii) the extent of each individual's capacity to repair damage (linked to homeostatic response). We anticipate this last, dynamic, aspect is inextricably linked to the others through the autonomic nervous system. The whole is dependent upon the status of the interconnected immune and inflammatory systems. This holistic approach leads us to propose various outcomes. For most, their body maintains homeostasis by routine repair. However, some develop electrohypersensitivity either due to RFR exposure or as an ANS-mediated, unconscious response (aka nocebo effect), or both. We suggest RFR exposure may be one factor in the others developing an auto-immune disease or allergy. A few develop delayed catastrophic disease such as glioma. This model gives the blanket term ElectroMagnetic Illness (EMI) to all RFR-related conditions. Thus, EHS appears to be one part of a range of responses to a novel and rapidly changing evolutionary situation.Abstracts are published as supplied and have not been subject to editorial review or correction.

This study sought to investigate the association between

F-fludeoxyglucose (

F-FDG) uptake in positron emission tomography/CT (PET/CT) scans and different programmed death ligand-1 (PD-L1) expression conditions in non-small cell lung cancer (NSCLC).

From October 2017 to December 2019, NSCLC was retrospectively identified in 419 consecutive patients who underwent

F-FDG PET/CT scans and PD-L1 expression tests using the PD-L1 22C3 assay. The association between clinicopathological characteristics and PD-L1 expression was assessed.

The frequency of PD-L1-positive tumours was 38.2% (160/419) in NSCLC. In NSCLC, the multivariate analysis showed a high maximum standardised uptake value (SUVmax) (

< 0.0001) and an EGFR wild type genotype (

= 0.027) was significantly associated with PD-L1-positivity. In adenocarcinoma (ADC), the multivariate analysis showed that a high SUVmax (

< 0.0001) was significantly associated with PD-L1-positivity. In NSCLC and ADC, a Mann-Whitney

test showed significant differences between groups with PD-L1 high expression and PD-L1 low expression levels in terms of SUVmax (

= 0.011 and

= 0.013, respectively). The results of the receiver operating characteristic curve analysis showed that the area under the curve of the SUVmax was 0.767 (95% CI, 0.720-0.814;

< 0.0001) and 0.712 (95% CI, 0.651-0.774;

< 0.0001) in NSCLC and ADC, respectively.

The study demonstrates that the SUVmax was significantly associated with PD-L1 expression in NSCLC and ADC. The SUVmax was significantly different between the PD-L1 high and low expression conditions, as quantified using a PD-L1 22C3 assay.

This study provides direct evidence that SUVmax as a metabolic biomarker may help select patients with NSCLC likely to benefit from pembrolizumab.

Performance status (PS) is a subjective assessment of patients' overall health. Quantification of physical activity using a wearable tracker (Fitbit Charge [FC]) may provide an objective measure of patient's overall PS and treatment tolerance.

Patients with colorectal cancer were prospectively enrolled into two cohorts (medical and surgical) and asked to wear FC for 4 days at baseline (start of new chemotherapy [± 4 weeks] or prior to curative resection) and follow-up (4 weeks [± 2 weeks] after initial assessment in medical and postoperative discharge in surgical cohort). Primary end point was feasibility, defined as 75% of patients wearing FC for at least 12 hours/d, 3 of 4 assigned days. Mean steps per day (SPD) were correlated with toxicities of interest (postoperative complication or ≥ grade 3 toxicity). A cutoff of 5,000 SPD was selected to compare outcomes.

Eighty patients were accrued over 3 years with 55% males and a median age of 59.5 years. Feasibility end point was met with 68 patients (85%) C can standardize patient assessment and help identify vulnerable population.

A review of the literature was performed to evaluate how quality of life measures are collected, analyzed, and reported in cancer clinical trials intended to support drug registration.Health-related quality of life (HRQoL) data points are one of the patient-reported outcome (PRO) assessments used in clinical trials to evaluate the effects of treatments from the patient perspective. The use of PROs has gained focus in cancer clinical trials as more options become available for greater longevity of patients on treatment. Standardization of PRO data is evolving and involves unique challenges when used for assessing biologic and chemotherapeutic agents for the treatment of cancer.

In this study, a review of literature published between 2009 and 2019 was conducted using PubMed, COCHRANE Library, and Medline. The research focus was on the current guidance, implementation, and reporting as well as highlighting the issues, and recommendations for the inclusion of HRQoL end points in cancer clinical trials intended for use in drug registration.

Although there exist many levels of guidance for HRQoL measures in cancer drug trials, challenges to operational implementation, the current inconsistent adherence to reporting standards, and the lack of consensus and understanding of analyses limit the value and potential of the resulting data collected.

The results of HRQoL data collected from cancer clinical trials can be difficult to interpret and apply to inform clinical decision making. Increased reporting and access to these data can provide opportunities for potential applications to improve translatability of HRQoL data collected in clinical trials into practice.
