Skin cancer risk among testicular germ-cell cancer survivors: a systematic review and meta-analysis.

Testicular germ-cell tumours (TGCT) are the most common cancer among young adult men. Previous studies suggested TGCT survivors have an increased risk for skin cancer. The goal of this study was to systematically review the literature and evidence regarding skin cancer risk among TGCT survivors compared with the general population. PubMed, EMBASE, Web of Science, Cochrane Databases and reference lists were included in the search. A systematic review of all comparative studies with more than 10 TGCT survivors reporting on skin cancer incidence was performed. A meta-analysis of the Standardized Incidence Rate (SIR) was calculated by pooling study-specific log-transformed estimates using the random-effects model. Risk of bias was assessed using the Newcastle-Ottawa Quality Assessment Scale. Nineteen studies that reported on 147 935 TGCT survivors were included. Pooled SIR for skin cancer and for melanoma incidence among TGCT survivors were 1.93 (95% CI 1.62-2.29, P < 0.0001) and 1.81 (95% CI 1.57-2.08, P < 0.0001), respectively. In conclusion, compared to the general population, TGCT survivors have an increased risk for developing skin cancer and melanoma. Additional long-term studies that include TGCT survivors, additional risk factors and all subtypes of skin cancer are required.

How to improve eRehabilitation programs in stroke care? A focus group study to identify requirements of end-users.

BACKGROUND: A user-centered design approach for eHealth interventions improves their effectiveness in stroke rehabilitation. Nevertheless, insight into requirements of end-users (patients/informal caregivers and/or health professionals) for eRehabilitation is lacking. The aim of this study was to identify end-user requirements for a comprehensive eHealth program in stroke rehabilitation. METHODS: Eight focus groups were conducted to identify user requirements; six with patients/informal caregivers and two with health professionals involved in stroke rehabilitation (rehabilitation physicians, physiotherapists, occupational therapists, psychologists, team coordinators, speech therapist). The focus groups were audiotaped and transcribed in full. Direct content analysis was used to identify the end-user requirements for stroke eHealth interventions concerning three categories: accessibility, usability and content. RESULTS: In total, 45 requirements for the accessibility, usability and content of a stroke eRehabilitation program emerged from the focus groups. Most requirements concerned content (27 requirements), followed by usability (12 requirements) and accessibility (6 requirements). Patients/informal caregivers and health professionals each identified 37 requirements, respectively, with 29 of them overlapping. CONCLUSIONS: Requirements between stroke patients/informal caregivers and health professionals differed on several aspects. Therefore, involving the perspectives of all end users in the design process of stroke eRehabilitation programs is needed to achieve a user-centered design. TRIAL REGISTRATION: The study was approved by the Medical Ethical Review Board of the Leiden University Medical Center [P15.281].

Why the uptake of eRehabilitation programs in stroke care is so difficult-a focus group study in the Netherlands.

BACKGROUND: The uptake of eRehabilitation programs in stroke care is insufficient, despite the growing availability. The aim of this study was to explore which factors influence the uptake of eRehabilitation in stroke rehabilitation, among stroke patients, informal caregivers, and healthcare professionals. METHODS: A qualitative focus group study with eight focus groups (6-8 participants per group) was conducted: six with stroke patients/informal caregivers and two with healthcare professionals involved in stroke rehabilitation (rehabilitation physicians, physical therapists, occupational therapists, psychologists, managers). Focus group interviews were audiotaped, transcribed in full, and analyzed by direct content analysis using the implementation model of Grol. RESULTS: Thirty-two patients, 15 informal caregivers, and 13 healthcare professionals were included. A total of 14 influencing factors were found, grouped to 5 of the 6 levels of the implementation model of Grol (Innovation, Organizational context, Individual patient, Individual professional, and Economic and political context). Most quotes of patients, informal caregivers, and healthcare professionals were classified to factors at the level of the Innovation (e.g., content, attractiveness, and feasibility of eRehabilitation programs). In addition, for patients, relatively many quotes were classified to factors at the level of the individual patient (e.g., patients characteristics as fatigue and the inability to understand ICT-devices), and for healthcare professionals at the level of the organizational context (e.g., having sufficient time and the fit with existing processes of care). CONCLUSION: Although there was a considerable overlap in reported factors between patients/informal caregivers and healthcare professionals when it concerns eRehabilitation as innovation, its seems that patients/informal caregivers give more emphasis to factors related to the individual patient, whereas healthcare professionals emphasize the importance of factors related to the organizational context. This difference should be considered when developing an implementation strategy for patients and healthcare professionals separately.

Attention needed for cognitive problems in patients after out-of-hospital cardiac arrest: an inventory about daily rehabilitation care.

AIM: Recent literature and Dutch guidelines for patients with out-of-hospital cardiac arrest (OHCA) recommend screening for cognitive impairments and referral to cognitive rehabilitation when needed. The aim of this study is to assess the uptake of these recommendations for OHCA patients. METHOD: An internet-based questionnaire was sent to 74 cardiologists and 143 rehabilitation specialists involved in rehabilitation of OHCA patients in the Netherlands. The questionnaire covered: background characteristics, availability and content of cognitive screening and rehabilitation, organisation of care, experienced need for an integrated care pathway including physical and cognitive rehabilitation, barriers and facilitators for an integrated care pathway. RESULTS: Forty-five questionnaires were returned (16 cardiologists and 29 rehabilitation doctors). Thirty-nine percent (n = 17) prescribed cognitive screening. Eighty-nine percent underscores an added value of an integrated care pathway. Barriers for an integrated care pathway included lack of knowledge, logistic obstacles, and poor cooperation between medical specialties. CONCLUSIONS: In the Netherlands, only a minority of cardiologists and rehabilitation specialists routinely prescribe some form of cognitive screening in OHCA patients, although the majority underscores the value of cognitive screening in OHCA patients in an integrated care pathway. The uptake of such a care pathway seems hindered by lack of knowledge and organisational barriers.

High survival rate of 43% in out-of-hospital cardiac arrest patients in an optimised chain of survival.

AIMS: Survival to hospital discharge after out-of-hospital cardiac arrest (OHCA) varies widely. This study describes short-term survival after OHCA in a region with an extensive care path and a follow-up of 1 year. METHODS: Consecutive patients ≥16 years admitted to the emergency department between April 2011 and December 2012 were included. In July 2014 a follow-up took place. Socio-demographic data, characteristics of the OHCA and interventions were described and associations with survival were determined. RESULTS: Two hundred forty-two patients were included (73 % male, median age 65 years). In 76 % the cardiac arrest was of cardiac origin and 52 % had a shockable rhythm. In 74 % the cardiac arrest was witnessed, 76 % received bystander cardiopulmonary resuscitation and in 39 % an automatic external defibrillator (AED) was used. Of the 168 hospitalised patients, 144 underwent therapeutic procedures. A total of 105 patients survived until hospital discharge. Younger age, cardiac arrest in public area, witnessed cardiac arrest, cardiac origin with a shockable rhythm, the use of an AED, shorter time until return of spontaneous circulation, Glasgow Coma Scale (GCS) ≥13 during transport and longer length of hospital stay were associated with survival. Of the 105 survivors 72 survived for at least 1 year after cardiac arrest and 6 patients died. CONCLUSION: A survival rate of 43 % after OHCA is achievable. Witnessed cardiac arrest, cardiac cause of arrest, initial cardiac rhythm and GCS ≥13 were associated with higher survival.

Thymidine phosphorylase and dihydropyrimidine dehydrogenase protein expression in colorectal cancer.

It is essential for actively proliferating cells to increase their rate of DNA synthesis to progress through the cell cycle. This is reflected in the increased uracil usage that is a common feature in solid tumours. Thymidine phosphorylase (TP) anabolises formation of pyrimidine nucleosides available for DNA synthesis, whereas dihydropyrimidine dehydrogenase (DPD) catabolises the degradation of pyrimidine bases, thereby reducing levels of uracil and thymine available for DNA synthesis. In addition, tissue levels of TP or DPD have been associated with the clinical efficacy of pyrimidine anti-metabolites commonly used in the treatment of colorectal cancer. There is little information, however, on the relative expression or degree of co-ordinated regulation of either protein in primary or metastatic colorectal cancer. DPD and TP protein levels were measured in 15 primary colorectal carcinomas, 10 colorectal liver metastases and 25 adjacent uninvolved tissues. DPD was reduced in 67% (10/15) of colorectal tumours (mean tumour/normal = 0.52) and in all liver metastases (mean tumour/normal = 0.41) compared with the corresponding normal tissue. In contrast, TP was increased in 80% (12/15) of colorectal tumours (mean tumour/normal = 18.91) and in all metastases (mean tumour/normal = 3.70). TP and DPD protein expression were highly variable in uninvolved and tumour tissues. The ratio of TP:DPD was higher in 87% of colorectal tumours and in all liver metastases compared with the adjacent uninvolved tissues. This suggests the presence of co-ordinated regulation of these pyrimidine metabolic enzymes and offers a strategy for optimising the use of pyrimidine-based chemotherapy.

Acquired aphasia in children after surgical resection of left-thalamic tumors.

Five children (three males, two females; four right-, one left-handed; age range 6 to 14 years) who developed aphasia after gross-total excision of left predominantly thalamic tumors are reported. Three patients had Broca aphasia, one had mixed transcortical aphasia, and one patient had conduction aphasia. In the months after surgery, three children improved while receiving radiation and/or chemotherapy, although none recovered completely. Two patients with malignant tumors developed worsening aphasia when the tumor recurred, and later died. Two of three patients tested had visuospatial difficulties in addition to language deficits. Attention and executive functioning were affected in three of three patients tested. Memory, verbal and/or visual functioning, were affected in four of four patients tested. Both patients who were tested showed transient right hemineglect. Two of two patients tested were probably apraxic. The wide range of deficits in these children highlights the importance of the thalamus and other subcortical structures in developing cognition.

Excitatory GABA responses in embryonic and neonatal cortical slices demonstrated by gramicidin perforated-patch recordings and calcium imaging.

Gramicidin perforated-patch-clamp recordings in brain slices were used to obtain an accurate assessment of the developmental change in the GABAA receptor reversal potential (EGABAA) in embryonic and early postnatal rat neocortical cells including neuroepithelial precursor cells, cortical plate neurons, and postnatal neocortical neurons. Our results demonstrate that there is a progressive negative shift in EGABAA with the most positive values found in the youngest cortical precursor cells. At the early stages of neocortical development, EGABAA is determined by the chloride (Cl-) gradient, and the internal chloride concentration ([Cl-]i) decreases with development. EGABAA is positive to the resting potential, indicating that GABA serves to depolarize developing neocortical cells. Consistent with this conclusion, GABAA receptor activation with muscimol was found-to increase the internal calcium concentration ([Ca2+]i) in both embryonic and early postnatal neocortical cells through the activation of voltage-gated calcium channels (VGCCs). Postnatal cells exhibit spontaneous postsynaptic synaptic currents, which are eliminated by bicuculline methiodide (BMI) but not glutamate receptor antagonists and reverse at the Cl- equilibrium potential. Likewise, brief spontaneous increases in [Ca2+]i, sensitive to BMI and TTX, are observed at the same ages, suggesting that endogenous synaptic GABAA receptor activation can depolarize cells and activate VGCCs. These results suggest that GABAA receptor-mediated depolarization may influence early neocortical developmental events, including neurogenesis and synaptogenesis, through the activation of Ca(2+)-dependent signal transduction pathways.

Fetomaternal hemorrhage as an etiology of neonatal stroke.

We report a term infant who presented with focal seizures and was diagnosed with a large left hemispheral infarct. Evaluation revealed extensive fetomaternal hemorrhage and subsequent neuroimaging disclosed a classic border zone infarct consistent with a hypoperfusion injury. We postulate that fetomaternal hemorrhage should be considered in the differential causation of neonatal stroke. The unilaterality of the lesion in this patient is difficult to explain.

Work redesign: a return to the basics.

Through a work redesign project, one hospital focuses on the root of the nursing care delivery system. The premise was simple--a return to the basics to redefine barriers, needed system changes, and role responsibilities. Successful outcomes include improved recruitment and retention as well as increased patient, staff and community satisfaction.

Accidents in old age.

Elderly persons particularly are liable to falls which in women often cause major fractures and other injuries. In Australia, some two per cent of deaths of women aged 65 and over are attributed to non-traffic accidents, and the length of hospital care and subsequent disability following fractures are both important aspects of the total morbidity resulting from falls suffered by older persons.
