Mindfulness-based stress reduction in cancer patients: impact on overall survival, quality of life and risk factor.

Mindfulness-based stress reduction, a complementary and alternative therapy, is able to decrease cancer-related fatigue, and stress and to improve the quality of life in cancer patients. Some studies evaluated if mindfulness-based stress reduction could improve some cardiometabolic and cancer risk factors, including systemic chemokines, growth factors, and pro-inflammatory biomarkers (e.g., C-reactive protein, Interleukin-1). In this narrative review, we highlight the pleiotropic beneficial effects of mindfulness-based stress reduction and its clinical impact on cardiovascular and cancer risk factors among patients with cancer in different stages. Moreover, improvements in the overall quality of life, sleep quality, and immune functions [changes in plasma levels of interleukin-4 (IL-4), interferon-γ (INF-γ), and interleukin-10 (IL-10)] will also be discussed. Albeit few clinical studies available in the literature, evidenced the beneficial effects of mindfulness-based stress reduction on the immune and cardiometabolic profile in cancer patients, providing important insights into the closest collaboration between psycho-oncologists, oncologists, and cardiologists.

Confirmatory validation analysis of the PROFFIT questionnaire to assess financial toxicity in cancer patients.

BACKGROUND: The Patient Reported Outcome for Fighting FInancial Toxicity (PROFFIT) questionnaire was developed to measure financial toxicity (FT) and identify its determinants. The aim of the present study was to confirm its validity in a prospective cohort of patients receiving anticancer treatment. PATIENTS AND METHODS: From March 2021 to July 2022, 221 patients were enrolled at 10 Italian centres. Selected items of the EORTC-QLQ-C30 questionnaire represented the anchors, specifically, question 28 (Q-28) on financial difficulties, and questions 29-30 measuring global health status/quality of life (HR-QOL). The study had 80% power to detect a 0.20 correlation coefficient (r) between anchors and PROFFIT-score (items 1-7, range 0-100, 100 indicating maximum FT) with bilateral alpha 0.05 and 80% power. Confirmatory factor analysis was conducted. FT determinants (items 8-16) were described. RESULTS: Median age of patients was 65 years, 116 (52.5%) were females, 96 (43.4%) had low education level. Confirmatory factor analysis confirmed goodness of fit of the PROFFIT-score. Significant partial correlation of PROFFIT-score was found with Q-28 (r = 0.51) and HR-QOL (r = -0.23). Mean (SD) PROFFIT-score at baseline was 36.5 (24.9); it was statistically significantly higher for patients living in South Italy, those with lower education level, those who were freelancer/unemployed at diagnosis and those who reported significant economic impact from the COVID-19 pandemic. Mean (SD) scores of determinants ranged from 17.6 (27.1) for item 14 (support from medical staff) to 49.0 (36.3) for item 10 (expenses for medicines or supplements). PROFFIT-score significantly increased with worsening response to determinants. CONCLUSIONS: External validation of PROFFIT-score in an independent sample of patients was successful. The instrument is now being used in clinical studies.

Health-related quality of life and psychosocial implications in testicular cancer survivors. A literature review.

OBJECTIVE: In this review, we focused our attention on Quality of Life (QoL) of testicular cancer survivors (TCSs), in general and in the most relevant areas. Several key findings have been highlighted in our review. MATERIALS AND METHODS: PubMed, MEDLINE and PsycINFO databases were consulted to find published studies, from 1980 to May 2017, that met our inclusion criteria. RESULTS: The majority of studies investigated older adult TCSs, while few studies on adolescent and young adult patients were available. Many studies indicate that health-related QoL (HRQoL) is similar among the TCSs and the general population. Even if QoL deteriorates so clear at the time of diagnosis and throughout treatment, afterward returns to normal levels, as defined by the matched controls. However, there are numerous chronic conditions consequent to diagnosis and treatment of testicular cancer that plague survivors and affect QoL, like Raynaud-like phenomena, peripheral neuropathy, fatigue, anxiety, sexual, fertility and body image problems. Even if these problems can have no effects on the measures of global QoL, they have an impact on the quality of life. Differences between TCSs with and without a partner bring to different outcomes in the adjustments to cancer. CONCLUSIONS: It is necessary to identify TCSs with higher risks of poorer QoL outcomes, to focus interventions on the areas with the greatest impairments. Further researches should consider the effects of testicular cancer on the impaired areas, collecting more data to better identify survivor's needs and consequent interventions, with a special focus on adolescent and young adult TCSs. Other works are requested on therapies, preventive and ameliorative, to reduce chronic side effects of testicular cancer treatment.

Topographic differences in amniotic fluid concentrations of prostanoids in women in spontaneous labor at term.

These studies were designated to determine if there are differences in prostanoid concentrations between amniotic fluid (AF) retrieved transvaginally from the membrane forebag (lower or forebag compartment) and fluid retrieved by transabdominal amniocentesis from the 'upper compartment' in women in labor. Fluid was retrieved from 53 women in active labor who underwent transabdominal and transvaginal amniocentesis. Fluid was assayed for prostaglandin E2 (PGE2) and prostaglandin F2 alpha (PGF2 alpha), 13,14-dihydro-15-keto-prostaglandin F2 alpha (PGFM), thromboxane B2 (TXB2), and 6-keto-prostaglandin F1 alpha (6-k-PGF1 alpha) using sensitive and specific radioimmunoassays. Concentrations of all prostanoids measured were significantly higher in fluid retrieved by transvaginal than transabdominal amniocentesis; the magnitude of the increase (measured as the ratio of concentrations in the lower/upper compartment) was higher for PGF2 alpha and TXB2 than for the other prostanoids measured; for each prostanoid measured, there was a significant correlation between the concentration in the upper and lower compartment.

An improved fragile X Southern blot probe without the CGGs eliminates background bands.

The largest of the commonly used probes for Southern blot diagnosis of fragile X mental retardation syndrome spans the CGG repeat cluster in the FMR-1 gene. This probe causes the appearance of 'common' or 'constant' background bands which occasionally complicate the interpretation of autoradiographic results. By removing a 357 bp Sphl to Nhel fragment containing the CGGs from the probe pE5.1, we constructed a probe which eliminates the background bands yet allows the use of a large probe (4.8 kb) to detect changes in the diagnostic 5.2 kb genomic EcoRl band. This CGG-deficient probe has been used in routine diagnostic cases as well as in second round testing of pE5.1-probed cases where enlarged mutant bands are suspected to comigrate with the background bands.

Visual impairment in hysteria.

We have reviewed the charts of 45 neuro-ophthamological patients diagnosed with 79 monocular visual field or visual acuity losses secondary to non-organic etiology. Our aim was to determine the percentage of patients that have improvement in vision. As part of the protocol, all patients had magnetic resonance images, pattern visual evoked potentials, and flash electroretinography in addition to complete neuro-ophthalmological examinations. A single physician performed both the initial and follow-up examinations of all patients. Thirty-three percent of these patients had visual field defects only, 62% had both visual field defects and visual acuity defects, and 5% had only visual acuity defects. After organic disease was ruled out, all were given a timetable for recovery and clear reassurance regarding their prognoses for visual recovery. Seventy-eight percent of these patients showed improvement or were normal, while 22% showed no improvement. Younger patients without obvious psychiatric disorder had better prognoses than older patients.

A simple fragile X PCR assay with 7-deazaguanine-substituted DNA visualized by ethidium bromide.

A deazaguanine-substituted DNA PCR product from FMR-1 (the fragile X mental retardation syndrome gene) can be efficiently visualized with ethidium bromide on standard agarose gels. Normal-sized alleles (less than 54 CGG repeats) generated strong, easily visible bands in the expected size range of 491-635 bp. Southern blot analysis and radioactive PCR on sequencing gels were used to verify that the 74 males (out of 245 total tested) whose DNA failed to generate a visible band contained premutations or full mutations. This technique can be used as an inexpensive screen for fragile X syndrome among developmentally delayed males.

The relationship between spontaneous rupture of membranes, labor, and microbial invasion of the amniotic cavity and amniotic fluid concentrations of prostaglandins and thromboxane B2 in term pregnancy.

OBJECTIVE: The purpose of this study was to examine the relationship between rupture of membranes, labor, and microbial invasion of the amniotic cavity and amniotic fluid concentrations of eicosanoids in patients with spontaneous rupture of membranes at term. STUDY DESIGN: Amniotic fluid was retrieved by transabdominal amniocentesis from patients with rupture of membranes and patients with intact membranes at term. Studies to determine the microbial state of the amniotic cavity included culture for bacteria and mycoplasmas, Gram stain, amniotic fluid white blood cell count, and Limulus amebocyte lysate. Eicosanoids (prostaglandin E2, prostaglandin F2 alpha and its stable metabolite, 6-keto-prostaglandin F1 alpha, and thromboxane B2) were determined with sensitive and specific radioimmunoassays validated for human amniotic fluid. Statistical inference was conducted with analysis of variance and linear contrast. RESULTS: (1) Spontaneous rupture of membranes at term was associated with a significant increase in amniotic fluid concentrations of all eicosanoids measured in this study except 6-keto-prostaglandin F1 alpha. (2) Early labor in patients with rupture of membranes was associated with a significant increase in the amniotic fluid concentration of all eicosanoids. (3) A significant increase in amniotic fluid eicosanoids in women with microbial invasion of the amniotic cavity could not be documented. CONCLUSIONS: Whereas preterm labor in the absence of microbial invasion of the amniotic cavity is not associated with a significant increase in amniotic fluid concentrations of prostaglandins, a clear increase was documented in women with early labor after spontaneous rupture of membranes. These observations suggest that there are fundamental differences in the biochemistry of term and preterm parturition.

High throughput parallel analysis of hundreds of patient samples for more than 100 mutations in multiple disease genes.

As more mutations are identified in genes of known sequence, there is a crucial need in the areas of medical genetics and genome analysis for rapid, accurate and cost-effective methods of mutation detection. We have developed a multiplex allele-specific diagnostic assay (MASDA) for analysis of large numbers of samples (> 500) simultaneously for a large number of known mutations (> 100) in a single assay. MASDA utilizes oligonucleotide hybridization to interrogate DNA sequences. Multiplex DNA samples are immobilized on a solid support and a single hybridization is performed with a pool of allele-specific oligonucleotide (ASO) probes. Any probes complementary to specific mutations present in a given sample are in effect affinity purified from the pool by the target DNA. Sequence-specific band patterns (fingerprints), generated by chemical or enzymatic sequencing of the bound ASO(s), easily identify the specific mutation(s). Using this design, in a single diagnostic assay, we tested samples for 66 cystic fibrosis (CF) mutations, 14 beta-thalassemia mutations, two sickle cell anemia (SCA) mutations, three Tay-Sachs mutations, eight Gaucher mutations, four mutations in Canavan disease, four mutations in Fanconi anemia, and five mutations in BRCA1. Each mutation was correctly identified. Finally, in a blinded study of 106 of these mutations in > 500 patients, all mutations were properly identified. There were no false positives or false negatives. The MASDA assay is capable of detecting point mutations as well as small insertion or deletion mutations. This technology is amenable to automation and is suitable for immediate utilization for high-throughput genetic diagnostics in clinical and research laboratories.
