Can trained volunteers provide psychosocial support to patients undergoing radiotherapy? The perspective of patients and volunteers

PurposeClinic-based psychosocial interventions, including volunteer-based ones, may be a cost-efficient and acceptable means of integrating psychosocial support into cancer care during radiotherapy. The present study evaluated a new psychosocial volunteer support program in a large radiotherapy clinic.Methods and MaterialsPatients were asked to complete a demographic and satisfaction with care questionnaire. Clinic volunteers were asked to report their interactions with patients on shift logs.ResultsOf the 182 participating patients, 93 (51%) recalled meeting a volunteer in the clinic, with the 2 most common support types provided being the following: “listening and caring,” and “information on services.” Analysis of 224 volunteers' shift logs indicated that almost all interactions (94%) were initiated by the volunteers, and almost half (47%) involved the patients' companions in the clinic. The most common support type documented was “information and navigation” (71%), followed by “emotional” (47%), “diversional” (21%), and “physical/practical” (17%) support.ConclusionsTrained volunteers can effectively provide clinic-based psychosocial support and information to a high proportion of radiotherapy patients. These findings demonstrate that volunteer support is a feasible means of meeting the psychosocial needs of patients with cancer attending outpatient radiotherapy clinics, who may not require or want professional psychosocial support.     

Long-term outcome after Bascom's cleft-lift procedure under tumescent local analgesia for pilonidal sinus disease: a cohort study

Aim

Bascom's cleft-lift procedure for pilonidal sinus disease under tumescent local analgesia is feasible and well tolerated with favourable short-term outcomes. We aimed to assess the 10-year treatment success rate after cleft-lift under tumescent local analgesia.

Method

This was a single-centre cohort study based on prospectively registered perioperative data and survey data with additional data from electronic medical records. The cleft-lift procedure was performed under tumescent local analgesia in a day-surgical setting at a tertiary referral hospital between 1 July 2008 and 31 March 2014. The primary outcome was the 10-year risk treatment success defined as complete wound healing within 180 days of surgery or no recurrence assessed with competing risk analyses. Secondary outcomes were time to complete wound healing, persistent pain and cosmetic satisfaction.

Results

Two hundred patients with complex pilonidal sinus disease were included. Indication was incomplete wound healing after pilonidal sinus surgery in 43 (21.5%) patients, recurrence after previous intervention in 78 (39.0%) or moderate to complex sinuses assessed by a consultant surgeon in 79 (39.5%). One hundred and ninety-five patients had complete wound healing within 180 days with a median time of 29 days (interquartile range 16–47). The cumulative risk of 10-year recurrence was 11.3% (95% CI 6.2%–16.4%) with a median follow-up time of 8.5 (1.0–10.7) years. Treatment success was 86.1% (95% CI 80.6%–91.5%). No significant predictors were associated with recurrence, and 90% of patients experienced no persistent pain.

Conclusion

Cleft-lift performed under tumescent local analgesia has an acceptable 10-year treatment failure rate, making the method feasible in a day-surgery setting.     

Clinical significance of corrosion of cemented femoral stems in metal-on-metal hips: a retrieval study

Purpose

The clinical significance of corrosion of cemented femoral stems is unclear. The purpose of this retrieval study was to: (1) report on corrosion at the stem-cement interface and (2) correlate these findings with clinical data.

Methods

We analysed cemented stems (n?=?36) composed of cobalt-chromium (CoCr) and stainless steel (SS) in a series of revised metal-on-metal hips. We performed detailed inspection of each stem to assess the severity of corrosion at the stem-cement interface using a scale of 1 (low) to 5 (severe). We assessed the severity of corrosion at each stem trunnion and measured wear rates at the head taper and bearing surfaces. We used non-parametric tests to determine the significance of differences between the CoCr and SS stems in relation to: (1) pre-revision whole blood Co and Cr metal ion levels, (2) trunnion corrosion, (3) bearing surface wear and (4) taper material loss.

Results

The corrosion scores of CoCr stems were significantly greater than SS stems (p?<?0.01). Virtually all stem trunnions in both alloy groups had minimal evidence of corrosion. The median pre-revision Co levels of implants with CoCr stems were significantly greater than the SS stems (p?<?0.01). There was no significant difference in relation to pre-revision Cr levels (p?=?0.521). There was no significant difference between the two stem types in relation to bearing wear (p?=?0.926) or taper wear (p?=?0.148).

Conclusions

Severe corrosion of cemented femoral stems is a common finding at our retrieval centre; surgeons should consider corrosion of CoCr stems as a potential source of metal ions when revising a hip.

     

Blue Hue in the Dermoscopy Setting: Homogeneous Blue Pigmentation, Gray-Blue Area, and/or Whitish Blue Veil?

In dermoscopy, the correct recognition of the single parameters is fundamental to achieve great diagnostic accuracy, but the scarce morphologic expression of a parameter may lead to diagnostic errors. We report the case of a 27-year-old white man presenting a pigmented lesion of the back, which was present since puberty. Clinical examination revealed on the back the presence of a flat, gray-blue lesion and at the periphery a small dark-brown papule. An assessment of the lesion by means of dermoscopy was performed. The purpose of this report was to analyze the Blue Hue in dermoscopy with its histopathologic correlates, starting with the discussion of a clinical case.     

Preoperative administration of controlled-release oxycodone as a transition opioid for total intravenous anaesthesia in pain control after laparoscopic cholecystectomy

Background  The complexity of pain from laparoscopic cholecystectomy and the need for treating incident pain provide rationale for multipharmacological analgesia. We investigated the preoperative administration of controlled-release (CR) oxycodone as transition opioid from remifentanil infusion for pain after laparoscopic cholecystectomy. Methods  Fifty consecutive patients undergoing laparoscopic cholecystectomy were randomly, double-blindly assigned to treatment group (n = 25, CR oxycodone: 1 h before surgery and 12 h after the first administration) or to the control group (n = 25, placebo: administered at the same intervals). General anaesthesia was maintained with propofol and remifentanil target-controlled infusions (TCIs). All patients received ketorolac 30 mg i.v. Tramadol i.v. was administered for patient-controlled analgesia (PCA) postoperatively. Numerical rating scale for pain at rest and at movement (NRSr and NRSi), tramadol consumption, times to readiness to surgery and awakening, times to modified Aldrete’s and modified Post-Anesthetic Discharge Scoring System (PADSS) >9 and side effects were evaluated. Results  All NRSr and NRSi and tramadol consumption were significantly lower in the treatment group. The oxycodone group showed higher modified Aldrete’s scores at each time and reached a PADSS >9 faster. Side effects and postoperative nausea and vomiting episodes were comparable. Conclusions  We demonstrated the success of a multipharmacological treatment including opioid premedication with CR oxycodone used as transition opioid for TCI remifentanil infusion; the treatment group showed lower pain scores and rescue analgesic consumption, shorter time to discharge from recovery room and from surgical ward, and the same incidence of side effects, comparably to controls.

Exploring Tai Chi in rheumatoid arthritis: a quantitative and qualitative study

Background  

Rheumatoid arthritis (RA) is a chronic, inflammatory and systemic disease which affects the musculoskeletal system. Exercise programmes are reported to improve physical functioning in patients with RA. Tai Chi is a traditional Chinese martial art which combines slow and gentle movements with mental focus. The purpose of this study was to study in which way Tai Chi group exercise impacted on disease activity, physical function, health status and experience in RA patients, applying quantitative and qualitative methods.     

Nutritional-inflammation status and resistance to erythropoietin therapy in haemodialysis patients.

BACKGROUND: Chronic kidney disease patients who are resistant to erythropoietin (EPO) treatment may suffer from malnutrition and/or inflammation. METHODS: In a cross-sectional study of haemodialysis patients, we investigated the relationship between the natural logarithm of the weekly EPO dose normalized for post-dialysis body weight and outcome measures of nutrition and/or inflammation [BMI, albumin and C reactive protein (CRP)] by means of multiple linear regression analysis. On the basis of the decile distribution of weekly EPO doses, we also evaluated four groups of patients: untreated, hyper-responders, normo-responders and hypo-responders. RESULTS: Six hundred and seventy-seven adult haemodialysis patients were recruited from five Italian centres. BMI and albumin were lower in the hypo-responders than in the other groups (21.3+/-3.8 vs 24.4+/-4.7 kg/m(2), P<0.001; and 3.8+/-0.6 vs 4.1+/-0.4 g/dl, P<0.001), whereas the median CRP level was higher (1.9 vs 0.8 mg/dl, P = 0.004). The median weekly EPO dose ranged from 30 IU/kg/week in the hyper-responsive group to 263 IU/kg/week in the hypo-responsive group. Transferrin saturation linearly decreased from the hyper- to hypo-responsive group (37+/-15 to 25+/-10%, P = 0.003), without any differences in transferrin levels. Ferritin levels were lower in the hypo-responsive than in the other patients (median 318 vs 445 ng/ml, P = 0.01). At multiple linear regression analysis, haemoglobin, BMI, albumin, CRP and serum iron levels were independently associated with the natural logarithm of the weekly EPO dose (R(2) = 0.22). CONCLUSIONS: Our findings support a clear association between EPO responsiveness and nutritional and inflammation variables in haemodialysis patients; iron deficiency is still a major cause of hypo-responsiveness.     

Locally-applied Collagenase and Regeneration of Transsected and Repaired Rat Sciatic Nerves

The possible effects of collagenase on peripheral nerve regeneration were evaluated after epineurial repair of rat sciatic nerves. In the control group the repair site was covered by fibrin adhesive and infused with isotonic saline and in the experimental group collagenase was infused into the fibrin adhesive. In the short term study the regeneration distance was measured by a pinch test four, six, or eight days postoperatively. In the long term study the evaluation of nerve regeneration and recovery of motor function was made by testing the tetanic contraction force of the anterior tibial muscle three months postoperatively. There were no significant differences between the two groups in either the short or long term. We conclude that locally-applied collagenase had no effect on peripheral nerve regeneration.     

Turbulent stress measurements downstream of three bileaflet heart valve designs in pigs

Objective: Mechanical heart valves can cause thromboembolic complications, possibly due to abnormal flow patterns that produce turbulence downstream of the valve. The objective of this study was to investigate whether three different bileaflet valve designs would exhibit clinically relevant differences in downstream turbulent stresses. Methods: Three bileaflet mechanical heart valves (Medtronic Advantage^®, CarboMedics© Orbis™ Universal and St. Jude Medical^® Standard) were implanted into 19 female 90 kg pigs. Blood velocity was measured during open chest conditions in the cross sectional area downstream of the valves with 10 MHz ultrasonic probes connected to a modified Alfred^® Pulsed Doppler equipment. As a measure of turbulence, Reynolds normal stress (RNS) was calculated at three different cardiac output ranges (3–4, 4.5–5.5, 6–7 L/min). Results: Data from 12 animals were obtained. RNS correlated with increasing cardiac outputs. The highest instantaneous RNS observed in these experiments was 47 N/m², and the mean RNS taken spatially over the cross sectional area of the aorta during systole was between 3 N/m² and 15 N/m². In none of the cardiac output ranges RNS values exceeded the lower critical limit for erythrocyte or thrombocyte damage for any of the valve designs. Conclusions: Reynolds normal stress values were below 100 N/m² for all three valve designs and the difference in design was not reflected in generation of turbulence. Hence, it is unlikely that any of the valve designs causes flow induced damage to platelets or erythrocytes.
