Closing the survivorship gap in children and adolescents with Hodgkin lymphoma

The treatment of Hodgkin lymphoma (HL) is one of early success. However, disease-free survival (DFS) does not reflect latent organ injury and its impact on health status and well-being beyond 5 years. In fact, we are at a crossroads, in terms of needing individualized approaches to maintain DFS, while minimizing late effects and preserving health-related quality of life (HRQoL). Premature morbidity and mortality translate to a high societal cost associated with the potential number of productive life years ahead in this population who are young at diagnosis. The discordance between short-term lymphoma-free survival and long-term health and HRQoL creates a “survivorship gap” which can be characterized for individuals and for subgroups of patients. The current review delineates contributors to compromised outcomes and health status in child and adolescent (paediatric) HL and frames the survivorship gap in terms of primary and secondary prevention. Primary prevention aims to titrate therapy. Secondary prevention entails strategies to intervene against late effects. Bridging the survivorship gap will be attained with enhanced knowledge of and attention to biology of the tumour and microenvironment, host genetic factors, HRQoL and sub-populations with disparate outcomes.     

CARMIL2-related immunodeficiency manifesting with photosensitivity

We report a case of a newly recognized primary immunodeficiency due to biallelic mutations in CARMIL2 manifesting as an actinic prurigo-like photodermatitis, allergic diathesis and recurrent infections in a child. We present this case to highlight a rare phenotype seen in this T-cell immunodeficiency and provide an overview of other dermatologic manifestations among published reports of this condition.     

Increased hand washing reduces influenza virus surface contamination in Bangkok households, 2009–2010

Within a hand‐washing clinical trial, we evaluated factors associated with fomite contamination in households with an influenza‐infected child. Influenza virus RNA contamination was higher in households with low absolute humidity and in control households, suggesting that hand washing reduces surface contamination.     

Emotional dysregulation,internalizing symptoms,and self-injurious and suicidal behavior: Structural equation modeling analysis

This study used structural equation modeling to examine the relationships between emotion dysregulation, internalizing symptoms, nonsuicidal self-injury (NSSI), and suicide. One hundred forty-eight undergraduates completed a brief structured interview and self-report measures of emotion dysregulation, internalizing symptoms, and NSSI and suicidal behaviors. Results indicated a significant indirect effect of emotion dysregulation on NSSI via internalizing symptoms and on suicide attempts via NSSI. Findings provide a more nuanced understanding of the indirect association between emotion dysregulation and NSSI and suicidal behaviors. Implications for the potential utility of targeting internalizing symptoms as well as emotion dysregulation in interventions addressing NSSI and suicidal behaviors are discussed.     

Self‐reported quantity of daily water intake and urine output in healthy young

Water is an essential nutrient and adequate intake and output of water is required for health maintenance. Water homeostasis is vital for life and optimal function and considerable interest surrounds the issue of recommendations for water consumption in healthy individuals. Few studies are available about self‐reported water intake and urine output. The aim of this study was to assess the quantity of water intake and urine output in 24‐h period in healthy young individuals. This prospective study was carried out on 31 students aged 18–24 years undergoing nursing education in a University during January 2011 in Sakarya, Turkey. Healthy young individuals were recruited for determination of the quantity of water taken in and urine excretion along 24 h; they recorded fluid input and urine output. The students collected the data during weekend break. In our study, the total daily fluid intake (mL) for females was 2082·6 ± 687·1 and the total daily fluid intake (mL) for males was 2720·8 ± 717·4. The total daily quantity of urine (mL) for females was 1623·4 ± 602·4 and the total daily quantity of urine (mL) for males was 1818·3 ± 420·6. This research may be the source for similar studies that could include seasonal changes, climates, cultures and different age groups.     

Facilitation of Serotonin Signaling by SSRIs is Attenuated by Social Isolation

Hypofunction of the serotonergic system is often associated with major depression and obsessive compulsive disorder (OCD). Selective serotonin reuptake inhibitors (SSRIs) are commonly prescribed to treat these disorders, and require 3–6 weeks of chronic treatment before improvements in the symptoms are observed. SSRIs inhibit serotonin''s transporter, and in doing so, increase extracellular serotonin concentrations. Thus, efficacy of SSRIs likely depends upon the brain''s adaptive response to sustained increases in serotonin levels. Individual responsiveness to SSRI treatment may depend on a variety of factors that influence these changes, including ongoing stress. Social isolation is a passive, naturalistic form of chronic mild stress that can model depression in rodents. In this study, we examined how 20-day treatment with the SSRI citalopram (CIT) alters marble-burying (MB), open field behavior, and serotonin signaling in single- vs pair-housed animals. We used in vivo voltammetry to measure electrically evoked serotonin, comparing release rate, net overflow, and clearance. Pair-housed mice were significantly more responsive to CIT treatment, exhibiting reduced MB and facilitation of serotonin release that positively correlated with the frequency of electrical stimulation. These effects of CIT treatment were attenuated in single-housed mice. Notably, although CIT treatment enhanced serotonin release in pair-housed mice, it did not significantly alter uptake rate. In summary, we report that chronic SSRI treatment facilitates serotonin release in a frequency-dependent manner, and this effect is blocked by social isolation. These findings suggest that the efficacy of SSRIs in treating depression and OCD may depend on ongoing stressors during treatment.     

Prevalence of HOXB13 mutation in a population of Ashkenazi Jewish men treated for prostate cancer

We performed a retrospective analysis of germline DNA samples from Ashkenazi Jewish men and a comparison group of non-Ashkenazi men treated for prostate cancer at our institution to determine the prevalence of HOXB13 G84E mutation in prostate cancer patients of Ashkenazi Jewish heritage, an ethnic group common to the New York City area. Patients were genotyped for G84E using a TaqMan assay (Applied Biosystems). Positive cases were confirmed using Sanger sequencing. Median age at prostate cancer diagnosis was 68 years for 889 Ashkenazi Jewish patients, 64 years for 920 non-Ashkenazi Jewish patients. The median follow up was 9 years for Ashkenazi Jewish patients and 8.8 years for non-Ashkenazi Jewish patients. Only 4 patients were found to be heterozygous carriers of G84E. They were all of non-Ashkenazi Jewish ancestry and were diagnosed at 70, 66, 78, and 49 years of age. Two of them presented with high-risk prostate cancer. The prevalence of G84E in the non-Ashkenazi sample was 0.4 %. HOXB13 G84E mutation was not observed in prostate cancer patients of Ashkenazi Jewish ancestry treated at our institution. Screening for G84E, therefore, may be unnecessary in Ashkenazi Jewish men if these results are validated by other studies.
