RESUMO
Free flap reconstruction is a common procedure with success rates greater than 99%. However, vascular complications may occur, resulting in flap failure. For this reason, early detection of vascular compromise is crucial for flap salvage. Vascular complications may be detected early by monitoring tissue oximetry parameter changes using near-infrared spectroscopy (NIRS). This method of noninvasive monitoring can evaluate changes in flap oxygenation levels caused by arterial and venous thrombosis before surgical reexploration. The goal of this study was to assess the validity of using NIRS oximetry for monitoring free flaps. We conducted a prospective cohort observational study of 10 patients undergoing breast reconstruction. We used the INVOS 7100 cerebral oximetry monitoring system (Medtronic, Dublin, Ireland) to provide 24-hr continuous postoperative monitoring of flap perfusion and compared the data with clinical assessment findings. The median patient age was 57 years (range = 41-61 years). Patients underwent immediate breast reconstruction with deep inferior epigastric perforator (DIEP) flap surgery (n = 4), delayed reconstruction with DIEP flap surgery (n = 4), transverse upper gracilis flap surgery (n = 1), and latissimus dorsi flap with lipofilling (n = 1). We successfully monitored all 10 flaps for 24 hr postoperatively. The overall flap survival rate was 100%. Findings of clinical examination, Doppler studies, and surgical outcome were consistent with NIRS monitoring. In conclusion, NIRS tissue oximetry could potentially provide a noninvasive method for effective postoperative monitoring of free flaps.

INTRODUCTION Erectile dysfunction is common after radical cystectomy; however, research on sexual dysfunction after this procedure is relatively scarce. Our goal was to evaluate the incidence of penile prosthesis implantation after radical cystectomy, with a focus on rural/urban disparity. MATERIALS AND METHODS: We used the SEER-Medicare database to identify patients with bladder cancer diagnosed between 1991-2009 who had a radical cystectomy (ICD-9 codes 57.7, 57.71, 57.79). The outcome was placement of a penile implant (ICD-9 codes 64.95 and 64.97). Covariates extracted included rural county status, age, race, ethnicity, marital status, geographic region, socioeconomic status, Charlson comorbidity, pathologic cancer stage, and type of urinary diversion. RESULTS: A total of 95 penile implants were performed in the 11,477 cystectomy patients (0.83%). Patients who had a penile implant were mostly from urban counties (85.1%) and in the Western region of the United States (83.9%). After controlling for covariates, rural patients who underwent an ileal conduit for urinary diversion were less likely to have a penile prosthesis procedure after radical cystectomy. CONCLUSIONS: Penile prosthetic procedures are uncommon in bladder cancer patients who have undergone radical cystectomy; therefore, sexual health should be considered and discussed with patients after radical cystectomy.

Freestanding (suspended) graphene films, with high electron mobility (up to ~200,000 cm2V-1s-1), good mechanical and electronic properties, could resolve many of the current issues that are hampering the upscaling of graphene technology. Thus far, attempts at reliably fabricating suspended graphene devices comprising metal contacts, have often been hampered by difficulties in exceeding sizes of 1 µm in diameter, if using UV lithography. In this work, area of suspended graphene large enough to be utilized in microelectronic devices, have been obtained by suspending a CVD graphene film over cavities, with top contacts defined through UV lithography with both wet and dry etching. An area of up to 160 µm2 can be fabricated as backgated devices. The suspended areas exhibit rippling of the surfaces which simultaneously introduces both tensile and compressive strain on the graphene film. Finally, the variations of the Fermi level in the suspended graphene areas can be modulated by applying a potential difference between the top contacts and the backgate. Having achieved large area suspended graphene, in a manner compatible with CMOS fabrication processes, together with enabling the modulation of the Fermi level, are substantial steps forward in demonstrating the potential of suspended graphene-based electronic devices and sensors.
RESUMO
BACKGROUND: The standard of care for operable, stage I, non-small-cell lung cancer (NSCLC) is lobectomy with mediastinal lymph node dissection or sampling. Stereotactic ablative radiotherapy (SABR) for inoperable stage I NSCLC has shown promising results, but two independent, randomised, phase 3 trials of SABR in patients with operable stage I NSCLC (STARS and ROSEL) closed early due to slow accrual. We aimed to assess overall survival for SABR versus surgery by pooling data from these trials. METHODS: Eligible patients in the STARS and ROSEL studies were those with clinical T1-2a (<4 cm), N0M0, operable NSCLC. Patients were randomly assigned in a 1:1 ratio to SABR or lobectomy with mediastinal lymph node dissection or sampling. We did a pooled analysis in the intention-to-treat population using overall survival as the primary endpoint. Both trials are registered with ClinicalTrials.gov (STARS: NCT00840749; ROSEL: NCT00687986). FINDINGS: 58 patients were enrolled and randomly assigned (31 to SABR and 27 to surgery). Median follow-up was 40·2 months (IQR 23·0-47·3) for the SABR group and 35·4 months (18·9-40·7) for the surgery group. Six patients in the surgery group died compared with one patient in the SABR group. Estimated overall survival at 3 years was 95% (95% CI 85-100) in the SABR group compared with 79% (64-97) in the surgery group (hazard ratio [HR] 0·14 [95% CI 0·017-1·190], log-rank p=0·037). Recurrence-free survival at 3 years was 86% (95% CI 74-100) in the SABR group and 80% (65-97) in the surgery group (HR 0·69 [95% CI 0·21-2·29], log-rank p=0·54). In the surgery group, one patient had regional nodal recurrence and two had distant metastases; in the SABR group, one patient had local recurrence, four had regional nodal recurrence, and one had distant metastases. Three (10%) patients in the SABR group had grade 3 treatment-related adverse events (three [10%] chest wall pain, two [6%] dyspnoea or cough, and one [3%] fatigue and rib fracture). No patients given SABR had grade 4 events or treatment-related death. In the surgery group, one (4%) patient died of surgical complications and 12 (44%) patients had grade 3-4 treatment-related adverse events. Grade 3 events occurring in more than one patient in the surgery group were dyspnoea (four [15%] patients), chest pain (four [15%] patients), and lung infections (two [7%]). INTERPRETATION: SABR could be an option for treating operable stage I NSCLC. Because of the small patient sample size and short follow-up, additional randomised studies comparing SABR with surgery in operable patients are warranted.

Background: This study aimed to assess the role of community pharmacists and their perception toward antimicrobial stewardship, in addition to identifying factors influencing their perception and practices in community pharmacy. Methods: A cross-sectional study was carried out among community pharmacists regarding antimicrobial stewardship. Convenience sampling was used to obtain the required sample from a community pharmacy in Baghdad. In total, 381 participants have completed the survey. Results: The majority of the participants (85.6%) strongly agreed/agreed that "antimicrobial stewardship programs reduce the problems of antibiotic resistance"; and 85.5% of them strongly agreed/agreed that community pharmacists required adequate training on antibiotics use. In addition, high percent of community pharmacists (88.4%) strongly agreed/agreed that pharmacists have a responsibility to take a prominent role in antimicrobial stewardship programs and infection-control programs in the health system. The total score of perception was significantly influenced by older age groups, postgraduate degrees, and experience of 6-10 years (p < 0.001). This study also showed that 65.4% of pharmacists always/often advise patients to continue the full course of antimicrobials, and 64.9% of them reported always/often considering clinical and safety parameters before dispensing antibiotics. The role of pharmacists was significantly influenced by the younger age group, females, higher degree in pharmacy, experience of 3-5 years, and medical complex pharmacy (p < 0.001). Conclusion: Community pharmacists have a good perception toward antimicrobial stewardship programs, but their role is still limited. More efforts are needed to design better strategies for antimicrobial stewardship in community pharmacy.
RESUMO
INTRODUCTION: Erectile dysfunction (ED) is a condition that affects millions of men worldwide and is characterized by the inability to achieve or maintain an erection for satisfactory sexual performance. There are numerous treatment options for ED, including medications, mechanical assist devices, and surgical management; however, first-line treatment is usually a phosphodiesterase 5 (PDE5) inhibitor. There is a growing interest in developing novel, efficacious PDE5 inhibitors that provide better quality, safety, and tolerability profiles with less adverse effects. Our review of udenafil, mirodenafil, youkenafil, lodenafil, and SLx-2101 analyzes the safety, efficacy, and pharmacokinetic properties of these new ED drugs. AREAS COVERED: Clinical trials demonstrated improved scores in questionnaires, such as the International Index of Erectile Function and Sexual Encounter Profile, for udenafil, mirodenafil, and lodenafil, while youkenafil and SLx-2101 revealed enhanced safety and tolerability in early pharmacokinetic studies. EXPERT OPINION: It is our opinion that more robust clinical trials are required before these medications can be made available in the United States. Additionally, the field of urology may benefit from pursuing other avenues of pharmacotherapy, such as injections, tablets with a different mechanism of action, or stem cell therapy, to restore the integrity of the endothelium within the penis.

Background: The prevalence of osteoarthritis (OA) of the first carpometacarpal (CMC) joint and subsequent thumb disability is rising. Abductor pollicis longus tendon interposition arthroplasty (APLTIA) has gained popularity as a procedure to alleviate pain and restore thumb function. Methods: A systematic review was performed to assess the current reported outcomes of APLTIA. Inclusion criteria involved clinical studies with case-series as the minimal accepted level of evidence. Our primary outcome focussed on PROMs data, whilst secondary outcomes focussed on objective measures of function and complications. Papers investigating pathologies other than CMC OA or procedures other than APLTIA were excluded. Results: Twelve studies were included (485 thumbs), all of which were observational in study design. APLTIA appears to be associated with a reduction in pain and functional improvement. APLTIA was not found to complicate further surgery. Conclusion: APLTIA may be associated with improvement in short-term pain relief and functional status. Further research is required to evaluate the benefits, duration of relief and long-term outcomes of APLTIA.
RESUMO
This article summarizes a student-led effort to improve tutor group interactions among second-year medical students in a hybrid problem-based learning (PBL) curriculum. Dissatisfaction with PBL had led to superficial tutorial discussions that students escaped to study for board certification exams. Following the PBL principle of using intrinsically motivating problems, the student investigators created board-style questions with accompanying facilitation guides for tutors to present as 'mini-problems' to stimulate case-related discussion. Tutor groups used and enjoyed the questions, but interaction quality did not improve. Like the hybrid curriculum itself, the intervention embodied conflicting educational philosophies; implementation challenges reflected the tension between them.
RESUMO
OBJECTIVE: : To review the literature on adult penile reconstruction due to Peyronie's disease, trauma and cosmesis, while emphasising specific surgical techniques and procedures such as phalloplasty, radial forearm free flap reconstruction, and penile transplant. METHODS: : A comprehensive review of the literature for the years 1992-2020 of the PubMed and SpringerLink databases was performed to identify articles on penile reconstruction. Search terms included 'penile reconstruction', 'penile trauma', 'phalloplasty', 'penile transplant', and 'treatment of Peyronie's'. Relevant articles were selected. All included studies were performed on adults and written in English. RESULTS: : We were able to identify 46 papers from PubMed and SpringerLink that included the research terms. From these, we included technical details of procedures and gleaned photographs of their works. Additionally, we included photographs from our institution's own plication surgery cases. CONCLUSIONS: : The field of adult penile reconstruction is performed for a plethora of reasons. From cosmetic to urgent and from routine to complex, it is most certainly a growing subset of Urology that plays a vital role for the men who need it. To our knowledge, this is the most up-to-date review of adult penile reconstruction.
RESUMO
OBJECTIVE: This study aimed to understand the dispensing practice of antibiotics in community pharmacy in Iraq, in addition to explore the community pharmacists' perception about dispensing antibiotics without prescription. METHODS: A qualitative design was conducted on community pharmacists in Baghdad, Iraq. Pharmacists were selected conveniently from different gender, age group, pharmacy type and years of experience. Face-to-face semi-structure interview was used with all the pharmacists to get in-depth understanding about their dispensing practice of antibiotics without prescription in community pharmacy. The data was coded and classified for thematic analysis. RESULTS: This study found that dispensing of antibiotics without prescription was a common practice in community pharmacy. Pharmacists' perception towards dispensing antibiotics without prescription was associated with the medical condition, safety and efficacy of antibiotics, patients request antibiotics by name, emergency cases, regular customer, promotions from pharmaceutical companies, saving time and cost, brand medications, and poor healthcare services. In addition, there were inadequate knowledge about antibiotic resistance and lack of awareness about antibiotic stewardship leading to inappropriate dispensing practice. CONCLUSIONS: Community pharmacists have poor perception towards dispensing antibiotics without prescription. Educational interventions about antibiotics use focusing on community pharmacists are needed. This will help to optimize the practice of dispensing of antibiotics in the community. In addition, training programs about antibiotic resistance are important to enhance pharmacists' understanding about antibiotic stewardship.
RESUMO
Penile rings are used to sustain erection in order to enhance sexual pleasure. They work by reducing the outflow of blood from the cavernosal tissue. However, if left for extended periods of time severe edema, urethral fistula, gangrene, and even complete loss of the distal penis can ensue, this is known as penile ring entrapment (PRE). Management poses particular challenges due to its rarity. Herein, we report our experience with three patients from our institution that presented with PRE and include a review of the approaches others have taken. We also propose a simpler and more effective grading scale to allow for easier communication between providers, as the current grading scales do not do so.
RESUMO
INTRODUCTION: Most primary care in Malaysia is provided by general practitioners in private practice. To date, little is known about how Malaysian General Practitioners (GPs) manage patients with depression. We surveyed privately practising primary care physicians in the state of Penang, Malaysia, in relation to their experience of the Malaysian Clinical Practice Guideline (CPG) in Major Depressive Disorder, their current practice and perceived barriers in managing depression effectively. MATERIAL AND METHODS: A questionnaire based on the study aims and previous literature was developed by the authors and mailed to all currently registered GPs in private clinics in Penang. Survey responses were analysed using SSPS version 21. RESULTS: From a total of 386 questionnaires distributed, 112 (29%) were returned. Half of the respondents were unaware of the existence of any CPG for depression. One quarter reported not managing depression at all, while one third used anxiolytic monotherapy in moderate-severe depression. Almost 75 % of respondents reported making referrals to specialist psychiatric services for moderate-severe depression. Time constraints, patient non-adherence and a lack of depression management skills were perceived as the main barriers to depression care. CONCLUSIONS: Our findings highlight the need to engage privately practising primary care physicians in Malaysia to improve their skills in the management of depression. Future revisions of the Malaysian Depression CPG should directly involve more GPs from private practices at the planning, development and implementation stages, in order to increase its impact.

This study was undertaken to assess the people's self-reported reading of medicine labels and its associated factors and to assess the sources of information about medicines among general public. A cross-sectional study was carried out among general public in the State of Penang, Malaysia. A total of 888 participants were conveniently selected and completed the survey. A self-administered questionnaire was used to obtain the data from all the participants. Most of the participants (74.2%) reported that they have adequate information about medicines provided on their medicine labels. In addition, 86.9% of them reported that they read their medicine's label for the directions of usage and 84.3% for the dosage instruction. However, 42.1% of the participants do not read their medicine's label for the active ingredients, and 33% of them do not read their medicine's label for the safety information. In addition, 36.5% of the respondents did not read the label of medicine for the symptoms which can be used for. However, females, Malay respondents, and higher education level (college/university) were more likely to self-reported the reading medicine's label. Females were more likely to read the labels of medicines compared with males (OR = 1.6, 95% CI 1.20-2.13, P = .001). The reading of medicine labels was predicted by females, Malay respondents, and higher educated people. Health educational programs are needed to clarify label's information that can help in concept of patient safety.

OBJECTIVES: The aim of this double-blind, randomized, sham-controlled study was to verify the blood pressure (BP)-lowering efficacy of externally delivered focused ultrasound for renal denervation (RDN). BACKGROUND: Nonrandomized, first proof-of-concept study and experimental evidence suggested that noninvasive techniques of RDN emerged as an alternative approach of RDN to invasive technologies. METHODS: WAVE IV, an international, randomized (1â:â1) sham-controlled, double-blind prospective clinical study, was prematurely stopped. Patients were enrolled if office BP was at least 160âmmHg and 24-h ambulatory BP was at least 135âmmHg, while taking three or more antihypertensive medications. The treatment consisted of bilateral RDN using therapeutic levels of ultrasound energy and the sham consisted of bilateral application of diagnostic levels of ultrasound energy. RESULTS: In the 81 treated patients neither changes in office BP at 12 and 24 weeks, nor changes in 24-h ambulatory BP at 24-week follow-up visit differed between the two groups significantly. Of note, no safety signal was observed. Adherence analysis disclosed full adherence in 77% at baseline and 82% at 6 months' follow-up visit. Post hoc analysis revealed that stricter criteria for stabilization of BP at baseline were associated with a numerically greater change in 24-h ambulatory BP in the RDN group than in the sham group. CONCLUSION: Our data did not prove that antihypertensive efficacy of the externally delivered focused ultrasound for RDN was greater than the sham effect. Stabilization of BP at baseline was identified as an important determinant of BP changes.

BACKGROUND: Patients' behaviour in making decisions regarding health is currently changing from passive recipients to recipients who play an active role in taking action to control their health and taking self-care initiatives. OBJECTIVES: This study was conducted to evaluate the health seeking behaviour among general public and its associated factors; and to evaluate the medicine taking behaviour in public and the practice of self-medication. METHODS: A cross-sectional study was undertaken among general public in Penang Island, Malaysia. A convenience sampling of 888 participants successfully completed the survey. Self-administered questionnaires were distributed among the residents in the north east of Penang Island. RESULTS: This study showed that most of the participants chose to consult the physician when they experience any health problems (66.7%), followed by self-medication (20.9%). The first action for consulting the physician was significantly predicted by Malay respondents and retired people (OR 3.05, 95% CI 1.04-8.89). The prevalence of self-medication was 54%. The practice of self-medication was significantly associated with Chinese participants, educated people, people with alone living status and people with more self-care orientation. CONCLUSION: Increasing the awareness of the public about the rational choice of getting medical assistance is a very important issue to control their health. A health education program is needed to increase the awareness about the use of medicines among the general public and to enable them to make the right decisions relating to health problems.
RESUMO
OBJECTIVE: The objective of this study is to explore the pattern and practice of medicine use among the general public; and to explore the key factors influencing medicine use among medicine users. METHODS: A qualitative approach using focus group discussions was conducted to get in-depth information about medicines use pattern and practice from the general public. Adult people who reported using medicines at the time of study or in the previous month were approached. Two focus group discussions were audio-recorded and transcribed verbatim. The obtained data were analysed using thematic content analysis. RESULTS: This study found that there are some misunderstanding about the appropriate use of medicines. The majority of the participants reported that they were complying with their medication regimen. However, forgetting to take medicines was stated by 4 participants while 2 participants stopped taking medicines when they felt better. In addition, 10 participants reporting using medicines according to their own knowledge and past experience. Whereas 4 participants took medicines according to other informal resources such as family, friends or the media. Seven participants have experienced side effects with using medicines, 4 of them informed their doctor while 3 participants stopped taking medicines without informing their doctor. CONCLUSION: There was a misunderstanding about medicines use in terms of medication compliance, self-management of the illness and the resources of information about using medicines. Many efforts are still needed from health care professionals to provide sufficient information about medicines use in order to decrease the risk of inappropriate use of medicines and to achieve better therapeutic outcome.
RESUMO
BACKGROUND: Smoking is a major public health problem, especially in Iraq. There is very little information had been documented regarding smoking risk factors and quit intention among Iraqi smokers. OBJECTIVES: The main objectives of this study are to determine smokers' knowledge and perception about smoking health risks; and to determine smoking behavior and quitting intentions among Iraqi smokers; as well as to predict the factors that may associate with quit intentions. METHODS: A cross-sectional study was conducted at the outpatient clinic in Tikrit Teaching Hospital, Tikrit City, Iraq. Adult smokers who are smoking cigarette everyday and able to communicate with the researcher were invited to participate in the study. A self-administered questionnaire was used to collect data from 386 participants. RESULTS: This study showed that smokers had low awareness about some risk effects of smoking such as lung cancer in nonsmokers (30.1%), impotence in male smokers (52.6%), premature ageing (64%), and stroke (66.3%). In addition, the high score of knowledge and perception was significantly associated with quitting intention. CONCLUSION: Smokers' knowledge and perception regarding smoking health effects were low, especially in terms of secondhand smokers. Many efforts needed from health policy-makers and health care professionals to disseminate information about the risks of smoking and health benefits of give up smoking.
RESUMO
OBJECTIVES: The aim of this study was to assess clinical safety and efficacy outcomes of renal denervation executed by an externally delivered, completely noninvasive focused therapeutic ultrasound device. BACKGROUND: Renal denervation has emerged as a potential treatment approach for resistant hypertension. METHODS: Sixty-nine subjects received renal denervation with externally delivered focused ultrasound via the Kona Medical Surround Sound System. This approach was investigated across 3 consecutive studies to optimize targeting, tracking, and dosing. In the third study, treatments were performed in a completely noninvasive way using duplex ultrasound image guidance to target the therapy. Short- and long-term safety and efficacy were evaluated through use of clinical assessments, magnetic resonance imaging scans prior to and 3 and 24 weeks after renal denervation, and, in cases in which a targeting catheter was used to facilitate targeting, fluoroscopic angiography with contrast. RESULTS: All patients tolerated renal denervation using externally delivered focused ultrasound. Office blood pressure (BP) decreased by 24.6 ± 27.6/9.0 ± 15.0 mm Hg (from baseline BP of 180.0 ± 18.5/97.7 ± 13.7 mm Hg) in 69 patients after 6 months and 23.8 ± 24.1/10.3 ± 13.1 mm Hg in 64 patients with complete 1-year follow-up. The response rate (BP decrease >10 mm Hg) was 75% after 6 months and 77% after 1 year. The most common adverse event was post-treatment back pain, which was reported in 32 of 69 patients and resolved within 72 h in most cases. No intervention-related adverse events involving motor or sensory deficits were reported. Renal function was not altered, and vascular safety was established by magnetic resonance imaging (all patients), fluoroscopic angiography (n = 48), and optical coherence tomography (n = 5). CONCLUSIONS: Using externally delivered focused ultrasound and noninvasive duplex ultrasound, image-guided targeting was associated with substantial BP reduction without any major safety signals. Further randomized, sham-controlled trials will be needed to validate this unique approach.

Minor illnesses in children are often cured at home with over the counter medicines. Even though there is a wide use of medicines among children, they rarely receive medical advice about their medications from doctors or pharmacists. The aim of this study is to evaluate children's beliefs about medicines as well as to explain what children know about medicines. A cross-sectional survey was used to collect data from four primary schools in Penang Island, Malaysia. The target population of this research was schoolchildren of 11 and 12 years old regardless of their gender and social status. A self-administration questionnaire was used to obtain the data from schoolchildren and their parents. After including all schoolchildren in grades five and six, the total sample size was 1000 children in addition to 1000 parents. This study found that most children have inadequate knowledge and false beliefs about the efficacy of medicines. Children's beliefs about the efficacy of medicines were affected by their age group, gender and race (p < .05). Females, older children and Chinese were more knowledgeable about the efficacy of medicines. Furthermore, the socio-economic status, parents' education level and parents' occupation influenced children's beliefs about medicines (p < .001). This study showed that children have misconception about medicines. The need for medicine education should be implemented to get more knowledgeable users of medicines in future. However, the role of health-care professional should be increased in terms of medicine education.
