The present study used diffusion-weighted imaging (DWI) to elucidate possible associations with tumor-infiltrating lymphocytes (TIL), tumor-stroma ratio and vimentin expression in head and neck squamous cell cancer (HNSCC).

30 patients with primary HNSCC of different localizations were involved in the study. DWI was obtained on a 3 T scanner. Apparent diffusion coefficients (ADC) images were analyzed with a whole lesion measurement using a histogram approach. TIL- and vimentin-expression was calculated on biopsy samples before any form of treatment.

Tumor-stroma ratio correlated with ADC kurtosis (r=0.46, p=0.01) and ADC skewness (r=0.42, p=0.02). Several ADC parameters were significantly different between stroma rich und tumor rich tumors. ADC entropy correlated significantly with the expression of TIL within the tumor compartment (r=0.44, p=0.01). No associations were identified between ADC parameters and vimentin expression.

ADC skewness and kurtosis histogram parameters can reflect tumor compartments in HNSCC. ADC entropy was associated with TIL of the tumor compartment but not with those of the stroma compartment, which emphasizes the ability of ADC histogram parameters to reflect distinctive differences of tumors.

Current research suggests a need to implement environmental, behavioral, and even nutritional interventions, with the objective of improving the comfort and stability of preterm newborn infants, as well as reducing their stress and pain levels. Several studies have used the salivary reactivity of cortisol to assess stress or pain in preterm infants. The aim of this study was to analyze the results of published randomized controlled trials that tested the effects of nonpharmacological interventions on cortisol as a treatment for heel lance pain/stress in preterm infants.

Published randomized controlled trials (RCTs) were searched in PubMed, Embase, CINHAL, Web of Science Cochrane Library, and Cochrane Database of Systematic Reviews, and six studies met the eligibility criteria. The quality of the included studies was appraised using Cochrane’s Collaboration tool.

The meta-analysis showed that non-pharmacological interventions were associated with a reduction in levels of salivary cortisol in comparison with other interventions and controls, with fixed effect mean differences of -0.11, and with a 95% C.I. of -0.28 to -0.05. Prone-nest position, breast milk odor, kangaroo care, and twins co-bedding led to a decrease in cortisol levels in saliva.

Future studies should be performed on nonpainful interventions in order to gain more knowledge about the regulation of cortisol in saliva in preterm infants with involving control group and larger sample sizes.

  AIMS To investigate characteristics of emerging adults accessing a specialized chronic non-cancer pain clinic and describe interventions offered and utilized by this group.

A retrospective chart review was conducted of emerging adults and middle-aged adults with chronic pain receiving care over a six-month period.

A chronic pain clinic in Southeastern Ontario.

82 participants comprised of 41 emerging adults (aged 18-29) and 41 middle-aged adults (aged 30-64) METHODS Groups were matched on sex and number of pain sites. Demographic and pain characteristics, interventions, referrals, and clinic utilization were examined using bivariate and multivariate analysis.

Emerging adults reported lower pain severity scores (t(80)=-2.15, p=.035), were more likely to receive referrals for additional consultation and/or diagnostic investigations (X

(1, n=82)=4.97, p=.026) and to have at least one psychology visit (X

=7.29, p=.007). Moreover, emerging adults with higher depression scores were more likely to see a psychologist (OR 1.23, 95% CI 1.014-1.492).

Pain presentation and care patterns differed between emerging adults and middle-aged adults. click here Increased use of non-pharmacologic interventions in emerging adults may reflect differences in pain presentations as well as clinician’s sensitivity to emerging adult’s particular developmental needs but further research is needed. Further research is needed to contribute to nurses’ understanding of the quality and efficacy of pain management approaches.

To assess the presence of pain, its location, intensity, and effects on the daily activities of patients with chronic kidney disease (CKD) undergoing hemodialysis (HD).

Patients with chronic kidney disease (CKD) undergoing hemodialysis (HD).

A systematic review.

We carried out search for articles published until December 2020, including publications in Portuguese, English, and Spanish during the past 15 years (2005-2020), using the Embase, SciELO, PubMed, and Web of Science databases. The following information was collected type of pain, pain treatment, pain assessment instrument, prevalence of pain, location, and influence of pain on quality of life.

Twenty-five studies were selected for a systematic review. These studies involved a total of 98,162 adult and elderly patients with CKD who were undergoing HD. There was a high prevalence of pain in patients with CKD on HD. The most frequent sites of pain were the head, back, bones, chest, and the upper and lower limbs. The presence of acute, chronic, neuropathic pain, and myalgia was also reported in the studies.
