Foreskin cutting beliefs and practices and the acceptability of male circumcision for HIV prevention in Papua New Guinea

Male circumcision (MC) reduces HIV acquisition and is a key public health intervention in settings with high HIV prevalence, heterosexual transmission and low MC rates. In Papua New Guinea (PNG), where HIV prevalence is 0.8%, there is no medical MC program for HIV prevention. There are however many different foreskin cutting practices across the country's 800 language groups. The major form exposes the glans but does not remove the foreskin. This study aimed to describe and quantify foreskin cutting styles, practices and beliefs. It also aimed to assess the acceptability of MC for HIV prevention in PNG.



Cross-sectional multicentre study, at two university campuses (Madang Province and National Capital District) and at two 'rural development' sites (mining site Enga Province; palm-oil plantation in Oro Province). Structured questionnaires were completed by participants originating from all regions of PNG who were resident at each site for study or work.



Questionnaires were completed by 861 men and 519 women. Of men, 47% reported a longitudinal foreskin cut (cut through the dorsal surface to expose the glans but foreskin not removed); 43% reported no foreskin cut; and 10% a circumferential foreskin cut (complete removal). Frequency and type of cut varied significantly by region of origin (p < .001). Most men (72-82%) were cut between the ages of 10-20 years. Longitudinal cuts were most often done in a village by a friend, with circumferential cuts most often done in a clinic by a health professional. Most uncut men (71%) and longitudinal cut men (84%) stated they would remove their foreskin if it reduced the risk of HIV infection. More than 95% of uncut men and 97% of longitudinal cut men would prefer the procedure in a clinic or hospital. Most men (90%) and women (74%) stated they would remove the foreskin of their son if it reduced the risk of HIV infection.



Although 57% of men reported some form of foreskin cut only 10% reported the complete removal of the foreskin, the procedure on which international HIV prevention strategies are based. The acceptability of MC (complete foreskin removal) is high among men (for themselves and their sons) and women (for their sons). Potential MC services need to be responsive to the diversity of beliefs and practices and consider health system constraints. A concerted research effort to investigate the potential protective effects of longitudinal cuts for HIV acquisition is essential given the scale of longitudinal cuts in PNG.
Mouth-washings with recombinant human granulocyte–macrophage colony stimulating factor (rhGM-CSF) do not improve grade III–IV oropharyngeal mucositis (OM) in patients with hematological malignancies undergoing stem cell transplantation. Results of a randomized double-blind placebo-controlled study

We investigated whether daily oral washings with recombinant human granulocyte–macrophage colony-stimulating factor (rhGM-CSF) solution improved grade III–IV oropharyngeal mucositis (OM) in patients with hematological malignancies undergoing stem cell transplantation. Forty-one consecutive patients (21 males and 20 females, median age (range) 44 (16–69) years) were prospectively randomized to perform daily mouth-washes with either a 400 μg rhGM- CSF (Molgramostin, Schering-Plough) solution (group A, n = 18) or with a saline solution (group B, n = 23). Primary end-points were the intensity of OM, night rest quality and characteristics of food intake. Secondary end-points were need for and duration of parenteral nutrition, oral and intravenous analgesic requirements, incidence of viral or fungal oral infections and development of neutropenic fever. No differences were found between the placebo and rhGM-CSF-treated groups regarding overall duration of OM, maximum grade, reduction in at least one grade of OM (nine patients (56%) in group A vs 13 patients (68%) in group B), reduction of spontaneous or swallowing-induced pain, improvement in oral food intake, use of parenteral nutrition or use of systemic analgesics. In conclusion, mouth-washings with a 400 μg of rhGM-CSF solution do not improve severe OM in hematological patients undergoing stem cell transplantation.
Computer-assisted myocardial blush quantification after percutaneous coronary angioplasty for acute myocardial infarction: a substudy from the TAPAS trial.

Myocardial reperfusion after acute myocardial infarction can be angiographically assessed by the myocardial blush grade (MBG) or TIMI Perfusion Grade. These scores are based on subjective human judgement and lead to a score of four categories. A more operator-independent way of scoring myocardial perfusion may facilitate research in this area.



We designed the 'Quantitative Blush Evaluator' (QuBE), a computer program which calculates a score for myocardial perfusion. This program will be freely available as open source software. The inter-observer concordance was 97.7%. We calculated values on prospectively collected angiograms in patients with acute ST-elevation myocardial infarction from the TAPAS trial. Quantitative blush evaluator values could be assessed on 790 out of 980 collected angiograms (81%). The QuBE score correlated significantly with MBG as determined by a core lab. The QuBE score predicted complete ST-elevation resolution, low enzyme levels, and 1 year survival (all P < 0.001). Quantitative blush evaluator value was an independent predictor of mortality at 1 year [OR 0.40 (0.17-0.90), P = 0.02].



The QuBE program provides a practical, freely available computer-assisted assessment of myocardial perfusion. The QuBE score provides a useful surrogate endpoint in trials of therapies aimed at improving myocardial reperfusion.
Reliability and predictive validity of the Food Technology Neophobia Scale

The recently developed Food Technology Neophobia Scale (FTNS) was further tested to assess scale reliability. On 2 occasions, 131 consumers responded to the FTNS, technologies descriptions and 'willingness to try' food technologies for 7 products. In the second session, they were offered foods to taste. 'Information seeking' was measured as a potential confounder of stability. The intra-class correlation was 0.86 and there was no difference between the FTNS scores (p>0.05). Correlations with 'willingness to try' novel technologies were -0.39 to -0.58. The FTNS is confirmed as a reliable and predictive measure of responses to novel food technologies.
Enhanced external counterpulsation (EECP) improves biomarkers of glycemic control in patients with non-insulin-dependent type II diabetes mellitus for up to 3 months following treatment

The purpose of the present study was to evaluate the potential clinical benefits of EECP on glycemic parameters [fasting plasma glucose (FPG), postprandial glucose (PPG120), glycosylated hemoglobin (HbA1c)] in patients with a clinical diagnosis of type II diabetes mellitus (T2DM). Thirty subjects (60.7 ± 1.9 years) with T2DM were randomly assigned (2:1 ratio) to receive either 35 1-h sessions of EECP (n = 20) or time-matched control of standard care (n = 10). FPG, PPG120, and HbA1c were evaluated before and at 48 h, 2 weeks, 3 and 6 months following EECP treatment or time-matched control. EECP significantly decreased FPG (−14.6 and −12.0 %), PPG120 (−14.6 and −13.5 %), and HbA1c (−11.5 and −19.6 %) 48 h following EECP and 2 weeks following EECP, respectively. HbA1c remained significantly reduced at 3 months following EECP (−14.3 %). The homeostasis model assessment of insulin resistance (−31.1 %) and whole-body composite insulin sensitivity index (+54.2 %) were significantly improved 48 h following EECP. Nitrite/nitrate (NO x ) was significantly increased 48 h following EECP (+48.4 %) and 2 weeks (+51.9 %) following EECP treatment. Our findings provide novel evidence that EECP improves glycemic control in patients with T2DM that persist for up to 3 months following treatment.
Performance of genotypic tropism testing on proviral DNA in clinical practice: results from the DIVA study group.

The DIVA study is aimed at setting up a standardized genotypic tropism-testing on proviral-DNA for the routine clinical diagnostic-laboratory.



Twelve local centres and 5 reference centres (previously cross-validated) were identified. For inter-center validation-procedure, 60 peripheral-blood mononuclear cells (PBMCs) aliquots from 45 HAART-treated patients were randomly chosen for population V3 sequencing on proviral-DNA at local HIV centre and at reference-laboratory. Viral tropism was predicted by Geno2Pheno algorithm (False Positive Rate [FPR] = 20%) as proposed by the European-Guidelines. Quantification of total HIV-1 DNA was based on a method described by Viard (2004).



Quantification of HIV-1 DNA was available for 35/45 (77.8%) samples, and gave a median value of 598 (IQR:252- 1,203) copies/10 PBMCs. A total of 56/60 (93.3%) samples were successfully amplified by both the reference and the local virological centers. The overall concordance of tropism prediction between local and reference centers was 54/56 (96.4%). Results of tropism prediction by local centers were: 33/54 (61.1%) R5 and 21/54 (38.9%) X4/DM.



There was high concordance in the genotypic tropism prediction based on proviral DNA among different virological centers throughout Italy. Our results are in line with other European studies, and support the use of genotypic tropism testing on proviral DNA in patients with suppressed plasma HIV-1 RNA candidate to CCR5-antagonist treatment.
One Reality: Augmenting How the Physical World is Experienced by combining Multiple Mixed Reality Modalities

Most of our daily activities take place in the physical world, which inherently imposes physical constraints. In contrast, the digital world is very flexible, but usually isolated from its physical counterpart. To combine these two realms, many Mixed Reality (MR) techniques have been explored, at different levels in the continuum. In this work we present an integrated Mixed Reality ecosystem that allows users to incrementally transition from pure physical to pure virtual experiences in a unique reality. This system stands on a conceptual framework composed of 6 levels. This paper presents these levels as well as the related interaction techniques.
Taurolidine is effective in the treatment of central venous catheter-related bloodstream infections in cancer patients.

Taurolidine is an antimicrobial agent that was originally used in the local treatment of peritonitis and was shown to be effective in the prevention of catheter-related bloodstream infections (CR-BSI). In this pilot study, we used taurolidine solution as an intravenous (i.v.) lock into the totally implantable intravascular devices of 11 consecutive oncological patients with catheter-related bloodstream infections not responding to systemic antimicrobial chemotherapy. All patients recovered completely from the infection. No adverse drug effects were seen. Three patients were successfully retreated for a recurrent infection. Our data suggest a beneficial role of taurolidine i.v. lock for the therapy of catheter-related bloodstream infections in oncological patients. Taurolidine i.v. lock application is feasible and could especially be useful in infections resistant to antibiotic chemotherapy.
Effects of atorvastatin versus fenofibrate on apoB-100 and apoA-I kinetics in mixed hyperlipidemia.

Kinetics of apo B and apo AI were assessed in 8 patients with mixed hyperlipidemia at baseline and after 8 weeks of atorvastatin 80 mg q.d. and micronised fenofibrate 200 mg q.d. in a cross-over study. Both increased hepatic production and decreased catabolism of VLDL accounted for elevated cholesterol and triglyceride concentrations at baseline. Atorvastatin significantly decreased triglyceride, total, VLDL and LDL cholesterol and apo B concentrations (-65%, -36%, -57%, -40% and -33%, respectively, P<0.05). Kinetic analysis revealed that atorvastatin stimulated the catabolism of apo B containing lipoproteins, enhanced the delipidation of VLDL1 and decreased VLDL1 production. Fenofibrate lowered triglycerides and VLDL cholesterol (-57% and -64%, respectively, P<0.05) due to enhanced delipidation of VLDL1 and VLDL2 and increased VLDL1 catabolism. Changes of HDL particle composition accounted for the increase of HDL cholesterol during atorvastatin and fenofibrate (18% and 23%, P<0.01). Only fenofibrate increased apo AI concentrations through enhanced apo AI synthesis (45%, P<0.05). We conclude that atorvastatin exerts additional beneficial effects on the metabolism of apo B containing lipoproteins unrelated to an increase in LDL receptor activity. Fenofibrate but not atorvastatin increases apo AI production and plasma turnover.
The effect of male circumcision on sexual satisfaction and function, results from a randomized trial of male circumcision for human immunodeficiency virus prevention, Rakai, Uganda.

To investigate the relationship between adult male circumcision and sexual satisfaction and function in men, as observational studies on the effect of adult male circumcision on sexual satisfaction show conflicting results.



We investigated self-reported sexual satisfaction and function among men enrolled in a randomized trial of male circumcision for human immunodeficiency virus (HIV) prevention conducted in Rakai, Uganda. In all, 4456 sexually experienced HIV-negative males aged 15-49 years were enrolled; 2210 were randomized to receive immediate circumcision (intervention arm) and 2246 to circumcision delayed for 24 months (control arm). Men were followed up at 6, 12 and 24 months, and information on sexual desire, satisfaction and erectile dysfunction was collected. These variables were compared between the study arms and over time within the study arms, using chi-square or Fisher's exact tests. The trial registration number is NCT00425984.



There were no differences between the study arms at enrollment and problems with sexual satisfaction and function were reported by <2% of participants in both study arms at all time points. At 6 months, no difficulty with penetration was reported by 98.6% of circumcised men and 99.4% of controls (P = 0.02), and no pain on intercourse was reported by 99.4% circumcised and 98.8% of uncircumcised men (P = 0.05). There were no differences between the study arms in penetration or dyspareunia at later visits. Sexual satisfaction increased from 98.0% at enrollment to 99.9% at 2 years among the controls (P < 0.001), but there was no trend in satisfaction among circumcised men (enrollment 98.5%, 2 years 98.4%, P = 0.8).



Adult male circumcision does not adversely affect sexual satisfaction or clinically significant function in men.
The patient simple clinical colitis activity index (P-SCCAI) can detect ulcerative colitis (UC) disease activity in remission: a comparison of the P-SCCAI with clinician-based SCCAI and biological markers.

To develop a patient-based Simple Clinical Colitis Activity Index (P-SCCAI) of ulcerative colitis (UC) activity and to compare it with the clinician-based SCCAI, C-reactive protein (CRP) and Physician's Global Assessment (PGA) of UC activity. Monitoring UC activity may give patients disease control and prevent unnecessary examinations.



Consecutive UC patients randomly completed the P-SCCAI either before or after consultation. Gastroenterologists assessed patients' UC activity on the same day. Overall agreement between SCCAI and P-SCCAI was calculated with Spearman's Rho and Mann-Whitney U test. Agreement regarding active disease versus remission and agreement at domain level were calculated by percent agreement and kappa (κ).



149 (response rate 84.7%) UC patients participated. P-SCCAI and SCCAI showed a large correlation (rs=0.79). The medians (IQR) of the P-SCCAI (3.78;0-15) tended to be higher than those of the SCCAI (2.86;0-13), although this difference did not reach statistical significance (z=1.71| p=0.088). In 77% of the cases the difference between clinicians' and patients' scores was not clinically different (i.e.≤2). Percentage agreement between clinicians and patients, judging UC as active or in remission, was 87%, rs=0.66, κ=0.66, indicating a substantial agreement. In general patients tended to report more physical symptoms than clinicians. C-Reactive protein (CRP) was found to have a significant association with both P-SCCAI and SCCAI (κ=0.32, κ=0.39 respectively) as was PGA (κ=0.73 for both indices).



The P-SCCAI is a promising tool given its substantial agreement with the SCCAI and its feasibility. Therefore, P-SCCAI can complement SCCAI in clinical care and research.
Stent for Life in Portugal: This initiative is here to stay.

Portugal has one of the lowest rates of primary percutaneous coronary intervention (p-PCI) in Western Europe. This study assessed the progress of Portuguese p-PCI performance indicators one year after Portugal joined the Stent for Life (SFL) initiative.



Two national surveys were carried out, each covering a period of one month: the first when Portugal joined the SFL in 2011 (Moment Zero), and the second one year later (Moment One). A total of 397 consecutive patients with probable ST-segment elevation myocardial infarction were enrolled (201 at Moment Zero and 196 at Moment One) from 15 centers. During this period, the number of patients who arrived at a local hospital without p-PCI decreased (62-47%; p=0.004) and transportation to a p-PCI hospital by the National Institute for Medical Emergencies (INEM) increased significantly (13-37%; p<0.001). Shorter times to revascularization were observed, due to shorter patient delay (118-102 min; p=0.008). Door-to-balloon delay and system delay remained unchanged.



Improvements in performance indicators for p-PCI demonstrate the success of the first year of the local SFL plan, which was mainly focused on raising public awareness of the need to use the INEM emergency services, which has reduced patient delay, and on improving secondary transportation.
A new technique of bladder neck reconstruction during radical prostatectomy in patients with prostate cancer

To evaluate continence after radical prostatectomy in prostate cancer patients, in whom a new method of the bladder neck reconstruction (BNR) using deep dorsal stitch was implemented (deep single stitch through all bladder layers directly dorsal to the bladder opening after ″ tennis racket″ reconstruction) and to provide justification for its use by means of anatomical study in cadavers.



Open radical retropubic prostatectomy was performed in 84 patients: 39 patients with a new BNR method used to improve continence and control group of 45 patients with standard ″tennis racket″ BNR. Median follow-up was 14 months in control group and 12 months in study group. Continence recovery was accessed early postoperatively and every 3 months thereafter. Anatomical study was performed on 2 male fresh cadavers reproducing two different BNR techniques to clarify any underlying continence related mechanisms.



Patients with new BNR achieved full continence significantly faster (p=0.041), but the continence rates after 12 months were similar between groups. The severity of incontinence up to month 9 was significantly reduced in BNR group. The anastomotic stricture rate was not affected. Applying new BNR to the cadaver model revealed effects on early continence, namely presence of proximal passive closure mechanism in area of bladder neck.



Continence in patients with the new BNR method using deep dorsal stitch recovered significantly faster. Moreover, a reduced grade of residual incontinence was documented. The effect was non-significant at month 12 of follow-up, meaning that only early effect was present.
Changes in ventilatory capacity and pulmonary gas exchange during systemic and pulmonary inflammation in humans.

The exact mechanism linking the systemic inflammatory response associated with sepsis to changes in lung function remains to be determined. In a human experimental model of inflammation, we investigated how acute systemic and local pulmonary inflammation affects ventilatory capacity and pulmonary gas exchange. Fifteen volunteers received Escherichia coli lipopolysaccharide (LPS) intravenously or endobronchially on two different study days. Blood samples were obtained hourly (t = 0-8 h) and spirometry was performed at baseline and after 8 h. Both interventions decreased ventilatory capacity compared to baseline (p < 0.01), and this was more pronounced after intravenous (forced expiratory volume in 1-s, FEV1 ; 0.6 L/12% reduction) compared to endobronchial (FEV1 ; 0.32 L/7% reduction) administration (p < 0.05). Furthermore, the alveolar-arterial oxygen difference increased after intravenous but not after endobronchial endotoxin. These findings indicate that pulmonary gas exchange is impaired to a greater extent during endotoxin-induced systemic inflammation than during endotoxin-induced local pulmonary inflammation.
Endovascular treatment using predominantly stent-assisted coil embolization and antiplatelet and anticoagulation management of ruptured blood blister-like aneurysms.

BBA is a rare type of intracranial aneurysm that is difficult to treat both surgically and endovascularly and is often associated with a high degree of morbidity/mortality. The aim of this study was to present clinical and angiographic results, as well as antiplatelet/anticoagulation regimens, of endovascular BBA treatment by using predominantly stent-assisted coil embolization.



Thirteen patients (men/women, 6/7; mean age, 49.3 years) with ruptured BBAs were included from 2 different institutions. Angiographic findings, treatment strategies, anticoagulation/antiplatelet protocols, and clinical (mRS) and angiographic outcome were retrospectively analyzed.



Eleven BBAs were located in the supraclinoid ICA, and 2 on the basilar artery trunk. Nine of 13 were ≤3 mm in the largest diameter, and 8/13 showed early growth before treatment. Primary stent-assisted coiling was performed in 11/13 patients, double stents and PAO in 1 patient, each. Early complementary treatment was required in 3 patients, including PAO in 2. In stent-placement procedures, altered periprocedural antiplatelet (11/12) and postprocedural heparin (6/12) protocols were used without evidence of thromboembolic events. Two patients had early rehemorrhage, including 1 major fatal SAH. Twelve of 13 BBAs showed complete or progressive occlusion at late angiographic follow-up. Clinical midterm outcome was good (mRS scores, 0-2) in 12/13 patients.



Stent-assisted coiling of ruptured BBAs is technically challenging but can be done with good midterm results. Reduced periprocedural and postprocedural antiplatelet/anticoagulation protocols may be used with a low reasonable risk of thromboembolic complications. However, regrowth/rerupture remains a problem underlining the importance of early angiographic follow-up and re-treatment, including PAO if necessary.
