The Outcomes of Adult Acquired Buried Penis Surgical Reconstruction.

Adult Acquired Buried Penis (AABP) is a morbid condition that often requires surgical intervention. This retrospective study of 46 patients who underwent AABP surgery from November 2017 to July 2023 evaluates surgical outcomes, functional outcomes, and patient-reported outcomes. The median follow-up (FU) was 46 months. Patients were categorized by surgical complexity using the Pariser classification, with 76.1% undergoing high-complexity procedures (Pariser ≥ III). Common comorbidities included obesity (58.7%), prior circumcision (52.2%), and hypertension (52.2%). The low-complexity group had a shorter hospital stay (p = 0.02). No other significant differences were noted between groups in terms of Body Mass Index, operative time, or FU. Sexual dysfunction (45.7%) and urinary issues (38.1%) were the main reasons for surgical consultation. Skin grafting was required in 63.0% of patients; partial graft loss was more common in full thicknes skin graft group (p = 0.04). Postoperative complications occurred in 32.6% of patients, 13.3% of which were classified severe (Clavien ≥ III). The median increase in stretched penile length was 2 cm. The recurrence rate was 21.7%. The 12-month recurrence-free survival rate was 89.1%. All groups saw significant improvements in urinary and sexual function post-surgery (p < 0.05), and high patient satisfaction was reported (90.3%). Despite the complication rate, AABP surgery significantly improves quality of life, with ongoing advancements in technique anticipated to enhance outcomes further.

Optimizing Women's Entrepreneurship to Enhance Family Domestic Income: A Case Study of Female Entrepreneurs in BatamThis study examines the role of women's entrepreneurship in enhancing domestic family income in Batam, a special economic zone with unique

This study examines the role of women's entrepreneurship in enhancing domestic family income in Batam, a special economic zone with unique socio-economic characteristics. The study employs a mixed-methods approach, integrating quantitative and qualitative designs to understand the factors influencing women's entrepreneurship and to develop optimization strategies. Quantitative data were collected through questionnaires distributed to 200 female entrepreneurs across 12 districts in Batam, while qualitative data were obtained through in-depth interviews, focus group discussions (FGD), and participant observations. Data analysis was conducted using variance-based structural equation modeling (PLS-SEM) and NVIVO software to analyze the complex relationships between variables. The results of the study indicate that women's education level, access to capital, and family support are critical factors influencing the success of entrepreneurship. Access to capital is proven to be a significant challenge, with barriers such as high interest rates and complex procedures. Additionally, the increase in family income derived from women's businesses contributes to improving family welfare, including children's education, health, and financial stability. Based on these findings, the study recommends the need for improved access to capital, the development of relevant entrepreneurial training programs, and supportive government policies to strengthen the role of women's entrepreneurship in Batam. This study is expected to contribute meaningfully to the literature on women's entrepreneurship and provide a foundation for the development of more effective policies in the future.

An improved laser flash method for thermal conductivity measurement of molten salts

Thermal conductivity measurement of high-temperature heat transfer fluids provides a crucial basis for designing utility-scale thermal systems. Molten salts are promising heat transfer and thermal storage fluids in high-temperature thermal energy storage systems, while the molten salt thermal conductivity obtained in existing studies exhibits large deviations due to the high experimental complexity and unstandardized test procedures. In this work, we improve the conventional laser flash analysis method by proposing a theoretical heat transfer model for multi-layer heat conduction and providing a near-optimal molten salt container design. With water as a test sample, the relative error of thermal conductivity measurement using the improved method is 6.3%. The thermal conductivity of Solar Salt from 250 to 400 ​°C, and of Hitec Salt from 160 to 250 ​°C are measured and compared with the previous work. Both results show that the thermal conductivity increases with the temperature rising. This work will promote the technology standardization for accurately acquiring the thermal conductivity of molten salts or other similar high-temperature heat transfer fluids.

All-In-One OsciDrop Digital PCR System for Automated and Highly Multiplexed Molecular Diagnostics.

Digital PCR (dPCR) holds immense potential for precisely detecting nucleic acid markers essential for personalized medicine. However, its broader application is hindered by high consumable costs, complex procedures, and restricted multiplexing capabilities. To address these challenges, an all-in-one dPCR system is introduced that eliminates the need for microfabricated chips, offering fully automated operations and enhanced multiplexing capabilities. Using this innovative oscillation-induced droplet generation technique, OsciDrop, this system supports a comprehensive dPCR workflow, including precise liquid handling, pipette-based droplet printing, in situ thermocycling, multicolor fluorescence imaging, and machine learning-driven analysis. The system's reliability is demonstrated by quantifying reference materials and evaluating HER2 copy number variation in breast cancer. Its multiplexing capability is showcased with a quadruplex dPCR assay that detects key EGFR mutations, including 19Del, L858R, and T790M in lung cancer. Moreover, the digital stepwise melting analysis (dSMA) technique is introduced, enabling high-multiplex profiling of seven major EGFR variants spanning 35 subtypes. This innovative dPCR system presents a cost-effective and versatile alternative, overcoming existing limitations and paving the way for transformative advances in precision diagnostics.

Racial disparities in breast cancer survival after treatment initiation in Brazil: a nationwide cohort study

Breast cancer is a public health priority in Brazil and ensuring equity in health care is one of the cancer control plan goals. Our aim was to present the first assessment on the influence of race or skin colour on breast cancer survival at the national level. In this nationwide cohort study, data on women who initiated treatment for breast cancer in the public health-care system (Sistema Unico de Saúde), Brazil, were assembled through record linkage of administrative and mortality information systems. The administrative information systems were the Outpatient Information System (data from high complexity procedure authorisations) and the Hospital Information System (data from hospitalisation authorisations). We included women aged 19 years or older who started treatment between Jan 1, 2008, and Nov 30, 2010; self-identified as having White, Black, or Brown race or skin colour; had tumour stage I-IV; and were treated with chemotherapy or radiotherapy, or both. Patients were followed up until Dec 31, 2015. Patients with only hormone therapy records or who underwent only surgery were excluded. The Kaplan-Meier method was used to estimate crude overall survival for race or skin colour by time since treatment initiation, and Cox regression to estimate all-cause mortality hazard ratios (HRs) before and after adjustment for other covariates. We identified 59 811 women treated for stage I-IV breast cancer. 37 318 (62·4%) women identified themselves as White, 18 779 (31·4%) as Brown, and 3714 (6·2%) as Black. 5-year overall survival probability was higher for White women (74% [95% CI 73-74]) than Black women (64% [62-65]; p<0·0001). In adjusted regression models stratified by the absence of hormone therapy, Black women had a 24% (HR 1·24 [95% CI 1·16-1·34]; p<0·0001) higher risk of all-cause death than White women, and in the presence of hormone therapy Black women had a 25% (1·25 [1·14-1·38]; p<0·0001) higher risk of all-cause death than White women. Black skin colour was identified as a statistically significant risk marker for lower 5-year survival probability and higher risk of all-cause death among women treated for breast cancer by the Sistema Unico de Saúde. Actions to understand and mitigate this unfair difference in health results are urgently needed.

Enhancing informed consent through multimedia tools in pediatric spinal surgery: a comprehensive review.

Pediatric spine surgery is a high complexity procedure that can carry risks ranging from pain to neurological damage, and even death. This comprehensive mini review explores current best practice obtaining valid and meaningful informed consent (IC) prior to pediatric spinal surgery, including modalities that support effective comprehension and understanding. An evaluation of the literature was performed to explore understanding of surgical IC by patients or their guardians and the role of multimedia tools as a possible facilitator. The evidence discussed throughout this review, based on legal and ethical perspectives, reveals challenges faced by patients and guardians in achieving comprehension and understanding, especially when facing stressful medical situations. In this context, the introduction of multimedia tools emerges as a patient-centered strategy to help improve comprehension and decrease pre-operative uncertainty. This review highlights the need for a tailored approach in obtaining IC for pediatric patients and suggests a potential role of shared decision-making (SDM) in the surgical discussion process.

Outpatient dental procedures carried out by Pediatric Dentists within Brazil's public healthcare system.

Brazil's public healthcare system (SUS) offers specialized oral health services to Brazilians, but the productivity of specialists, such as Pediatric Dentists, has not been characterized. Therefore, the objective of this study was to characterize the outpatient dental procedures (ODPs) carried out by Pediatric Dentists within the SUS. An epidemiological study with an ecological, longitudinal, retrospective, and quantitative approach was conducted. The ODPs carried out by Pediatric Dentists within the SUS were characterized based on type of procedure, complexity level, and circumstance (urgent or elective). Data were analyzed using a descriptive and analytical approach, considering a significance level of 5%, as well as the impact of the COVID-19 pandemic (the 2020-2022 years were not included in secondary analyses). In the last 15 years, 29,234,972 ODPs were carried out by Pediatric Dentists within the SUS. Clinical procedures were the majority (55.4%), significantly more frequent than all other types of procedures (all p <0.05). Among these, restorative and periodontal procedures were the most common (30.7% and 21.0%, respectively). From 2008 to 2019, excluding COVID-19 pandemic years, the trend over the last 15 years was constant for all types of procedures (all p >0.05). In addition, low complexity ODPs were the majority (90.1%), significantly more frequent than medium (9.7%) and high complexity procedures (0.1%) (both p <0.05). At last, most ODPs were not characterized by circumstance in the outpatient production reports (96.9%). Therefore, it was possible to conclude that Pediatric Dentists carried out diverse ODPs within the SUS over the past 15 years, although there was a dominant pattern of type and complexity.

Amino Acid Profiles in the Biological Fluids and Tumor Tissue of CRC Patients.

Amino acids are the building blocks of proteins and essential players in pathways such as the citric acid and urea cycle, purine and pyrimidine biosynthesis, and redox cell signaling. Therefore, it is unsurprising that these molecules have a significant role in cancer metabolism and its metabolic plasticity. As one of the most prevalent malign diseases, colorectal cancer needs biomarkers for its early detection, prognostic, and prediction of response to therapy. However, the available biomarkers for this disease must be more powerful and present several drawbacks, such as high costs and complex laboratory procedures. Metabolomics has gathered substantial attention in the past two decades as a screening platform to study new metabolites, partly due to the development of techniques, such as mass spectrometry or liquid chromatography, which have become standard practice in diagnostic procedures for other diseases. Extensive metabolomic studies have been performed in colorectal cancer (CRC) patients in the past years, and several exciting results concerning amino acid metabolism have been found. This review aims to gather and present findings concerning alterations in the amino acid plasma pool of colorectal cancer patients.

TOTAL LAPAROSCOPIC DUODENOPANCREATECTOMY CASE REPORT

Total LaproscopicDuodenopancreatectomy (TLDP) was first done by Gagner in 1994 and considered a high complexity procedure. We present the first case published of TLDP done in Saudi Arabia according to our research in PubMed, Cochrane, Lilacs, and Bireme. A 35-year-old lady underwent successfully TLDP with surgery time of 480 minutes, no blood loss and 84h post op recovery. Surgical specimen showed ductal Adenocarcinoma of the head of pancreas, with invasion to the duodenum at the level of the ampulla, free margins and N0. Despite there is still no clear consensus of the advantage of TLDP over open duodenopancreatectomy, it provides faster recovery for the patients to start chemotherapy.

Which Volume Matters More? Systematic Review and Meta-Analysis of Hospital vs Surgeon Volume in Intra-Abdominal Emergency Surgery.

Understanding the impact of hospital and surgeon volume on emergency intra-abdominal surgery procedures and determining which measure is more influential in improving outcomes can guide regionalization of care. This systematic review, meta-analysis, and meta-regression synthesizes evidence regarding the impact of hospital and surgeon volume on mortality. A literature search without language restriction was performed in the PubMed, Web of Science, and Cochrane databases. Cohort studies assessing the impact of hospital/surgeon volume on mortality after intra-abdominal emergency procedures with data collected after the year 2000 were included and analyzed using a random effects model. A sub-group analysis assessing impact of hospital volume on high and low complexity procedures and ruptured aortic artery aneurysm (RAAA) repair was performed. Another sub-group analysis comparing high-volume surgeons in a low-volume hospital and low-volume surgeons in a high-volume hospital was also performed. PROSPERO: CRD42022358879. The search yielded 2153 articles, of which 33 cohort studies were included and determined to be good quality using the Newcastle Ottawa Scale. In 22 studies with available data for the meta-analysis, mortality was significantly higher in the low hospital volume and low surgeon volume cohort. The sub-group analysis found significantly higher mortality only in high complexity procedures and RAAA repair. Mortality was significantly lower in the cohort with high-volume surgeons at low-volume hospitals. High hospital volume was associated with lower mortality in all except low-complexity intra-abdominal emergency procedures. High surgeon volume was associated with lower mortality and there is limited evidence of it being the most protective.

Intraoperative hypotension in ambulatory surgery centers

Study objectivesTo measure the incidence of intraoperative hypotension (IOH) during surgery in ambulatory surgery centers (ASCs) and describe associated characteristics of patients and procedures. DesignRetrospective analysis. Setting20 ASCs. Patients16,750 patients having non-emergent, non-cardiac surgery; ASA physical status 2 through 4. InterventionsNone. MeasurementsWe assessed incidence of IOH using the definition from the Centers for Medicare & Medicaid Services (CMS) Merit-based Incentive Payment System (MIPS)—mean arterial pressure (MAP) < 65 mmHg for at least 15 cumulative minutes—and three secondary definitions: minutes of MAP <65 mmHg, area under MAP of 65 mmHg, and time-weighted average MAP <65 mmHg. Main results30.9% of ASC cases had a MAP <65 mmHg for at least 15 min. The incidence of IOH varied significantly, and was higher among younger adults (age 18–39; 36.2%), females (35.2%), and patients with ASA physical status 2 (32.8%). IOH increased with increasing surgery length, even when time-weighted, and was higher among low complexity (30.6%) than moderate complexity (28.8%) procedures, and highest among high complexity procedures (44.1%). ConclusionsThere was substantial occurrence of IOH in ASCs, similar to that described in academic hospital settings in previous literature. We hypothesize that this may reflect clinician preference not to intervene in perceived healthy patients or assumptions about ability to tolerate lower blood pressures on behalf of these patients. Future research will determine whether IOH in ACSs is associated with adverse outcomes to the same extent as described in more complex hospital-based surgeries.

Broad- Versus Narrow-Spectrum Perioperative Antibiotics and Outcomes in Pediatric Congenital Heart Disease Surgery: Analysis of the Vizient Clinical Data Base.

Despite guidelines recommending narrow-spectrum perioperative antibiotics (NSPA) as prophylaxis for most children undergoing congenital heart disease (CHD) surgery, broad-spectrum perioperative antibiotics (BSPA) are variably used, and their impact on postoperative outcomes is poorly understood. We used administrative data from U.S. hospitals participating in the Vizient Clinical Data Base. Admissions from 2011 to 2018 containing a qualifying CHD surgery in children 0-17 years old were evaluated for exposure to BSPA versus NSPA. Propensity score-adjusted models were used to compare postoperative length of hospital stay (PLOS) by exposure group, while adjusting for confounders. Secondary outcomes included subsequent antimicrobial treatment and in-hospital mortality. Among 18 088 eligible encounters from 24 U.S. hospitals, BSPA were given in 21.4% of CHD surgeries, with mean BSPA use varying from 1.7% to 96.1% between centers. PLOS was longer for BSPA-exposed cases (adjusted hazard ratio 0.79; 95% confidence interval [CI]: 0.71-0.89, P < .0001). BSPA was associated with higher adjusted odds of subsequent antimicrobial treatment (odds ratio [OR] 1.24; 95% CI: 1.06-1.48), and there was no significant difference in adjusted mortality between exposure groups (OR 2.06; 95% CI: 1.0-4.31; P = .05). Analyses of subgroups with the most BSPA exposure, including high-complexity procedures and delayed sternal closure, also did not find (but could not exclude) a measurable benefit from BSPA on PLOS. BSPA use was common in high-risk populations, and varied substantially between centers. Standardizing perioperative antibiotic practices between centers may reduce unnecessary broad-spectrum antibiotic exposure and improve clinical outcomes.

Consensus guidelines for the perioperative management of patients undergoing endoscopic retrograde cholangiopancreatography

Deep sedation without tracheal intubation (monitored anaesthesia care) and general anaesthesia with tracheal intubation are commonly used anaesthesia techniques for endoscopic retrograde cholangiopancreatography (ERCP). There are distinct pathophysiological differences between monitored anaesthesia care and general anaesthesia that need to be considered depending on the nature and severity of the patient's underlying disease, comorbidities, and procedural risks. An international group of expert anaesthesiologists and gastroenterologists created clinically relevant questions regarding the merits and risks of monitored anaesthesia care vs general anaesthesia in specific clinical scenarios for planning optimal anaesthetic approaches for ERCP. Using a modified Delphi approach, the group created practical recommendations for anaesthesiologists, with the aim of reducing the incidence of perioperative adverse outcomes while maximising healthcare resource utilisation. In the majority of clinical scenarios analysed, our expert recommendations favour monitored anaesthesia care over general anaesthesia. Patients with increased risk of pulmonary aspiration and those undergoing prolonged procedures of high complexity were thought to benefit from general anaesthesia with tracheal intubation. Patient age and ASA physical status were not considered to be factors for choosing between monitored anaesthesia care and general anaesthesia. Monitored anaesthesia care is the favoured anaesthesia plan for ERCP. An individual risk-benefit analysis that takes into account provider and institutional experience, patient comorbidities, and procedural risks is also needed.

A prospective study evaluating perioperative quality metrics of cancer surgery: Experience from a tertiary care cancer centre in India.

Well-defined quality metrics were studied at this high-volume tertiary care academic oncology centre to evaluate surgical quality and outcomes. A prospective cohort of 691 patients undergoing major surgeries for all cancers was observed between 1 September 2018 and 30 August 2019 and predefined quality indicators in three categories: namely, optimal hospital resource utilisation, quality of surgery and perioperative outcomes were recorded during their admission period. Surgical procedures were divided into group I versus group II involving simple/moderate complexity versus high complexity procedures for analysis done using appropriate tests in STATA v14.0. There were 373 versus 318 patients in group I versus group II with a mean of 48 years of age and 459 (66.43%) being females. Mean BMI was 24.58 kg/m2 , haemoglobin 12.12 g/dL and mean serum albumin of 4.25 g (SD ± 0.6). A total of 667(96.53%) patients had an Eastern Co-Operative Oncology Group performance score of 1 with 271 (39.22%) having comorbidities and 195 (28.22%) having tobacco/alcohol addictions. A total of 393 (56.87%) patients underwent prehabilitation. 83% of patients belonged to lower-middle socioeconomic status and 32% of patients had some prior surgical intervention. Neoadjuvant therapy was administered in 44.5% versus 37.42%, mean preoperative hospital stay was 3.65 versus 6.16 days whereas postoperative was 2.6 versus 6.09 days with total stay being 6.27 versus 12.21 days, mean surgical duration was 132 versus 268 min with mean blood loss of 100 versus 245 mL (group I vs. group II, respectively). Intraoperative events, namely, unexpected bleeding and hypotension occurred in 144 (20.84%) patients while packed red blood cells and/or fresh frozen plasma transfusion was required in 56 (8.1%) patients. 40% of patients needed intensive care unit care postoperatively with 45 (6.51%) patients having some event (hypotension, sepsis, acute kidney injury, etc.). A total of 29 (<4%) patients had ≥grade 3 surgical complications while ≥grade 2 medical complications occurred in 6.43% versus 12.58% of patients (group I vs. group II). A total of 90 (13.02%) patients were readmitted, 15 (2.17%) re-explored and 5 (0.72%) patients died. Optimal surgical outcomes in this study compared to international standards underpin the need for well-defined multidisciplinary perioperative pathways to be followed for each organ system and this framework can be adopted by other cancer centres in LMIC to achieve good surgical outcomes.

Association of Obstructive Sleep Apnea With Postoperative Delirium in Procedures of Moderate-to-High Complexity: A Hospital-Registry Study.

Patients suffering from obstructive sleep apnea (OSA) experience chronic sleep disturbances and desaturation, factors that have been associated with postoperative delirium and that can be aggravated after anesthesia for complex procedures. We investigated whether OSA is associated with delirium after anesthesia, and whether this association is modified by procedural complexity. Hospitalized patients ≥60 years who underwent general anesthesia or procedural sedation for procedures of moderate-to-high complexity between 2009 and 2020 at a tertiary health care network in Massachusetts were included. The primary exposure was OSA, defined based on International Classification of Diseases ( Ninth/Tenth Revision, Clinical Modification ) ( ICD-9 / 10-CM ) diagnostic codes, structured nursing interviews, anesthesia alert notes, and a validated risk score (BOSTN [body mass index, observed apnea, snoring, tiredness, and neck circumference]). The primary end point was delirium within 7 days after the procedure. Multivariable logistic regression and effect modification analyses adjusted for patient demographics, comorbidities, and procedural factors were applied. A total of 46,352 patients were included, of which 1694 patients (3.7%) developed delirium, 537 (3.2%) with OSA, and 1,157 (4.0%) without OSA. In adjusted analyses, OSA was not associated with postprocedural delirium in the overall cohort (adjusted odds ratio [OR adj ], 1.06; 95% confidence interval [CI], 0.94-1.20; P = .35). However, a high procedural complexity modified the primary association ( P value for interaction = .002). OSA patients had a higher risk of delirium after high-complexity procedures (≥40 work relative value units) such as cardiac (OR adj , 1.33; 95% CI, 1.08-1.64; P = .007, P value for interaction = .005) or thoracic surgery (OR adj , 1.89; 95% CI, 1.19-3.00; P = .007, P value for interaction = .009), but no increased risk after moderate complexity procedures, including general surgery (OR adj , 0.86; 95% CI, 0.55-1.35; P = .52). Compared to non-OSA patients, a history of OSA is associated with a higher risk after high-complexity procedures such as cardiac or thoracic surgery but not after procedures of moderate complexity.

Residency graduates should not be expected to perform hypospadias repair without fellowship training: Results from a survey of SPU membership

Trainee autonomy has eroded over time as surgery has become more subspecialized and as attending oversight has increased, causing many trainees to seek additional fellowship training beyond residency. Less clear is whether there are cases that attendings view as "fellowship-level" or "privileged" cases in which resident-level trainees should not have high levels of autonomy due to complexity or high-stakes outcomes. We sought to better understand current attitudes and practices with regards to trainee autonomy in hypospadias repair as it represents a high complexity procedure within pediatric urology. We administered a RedCap survey to the SPU membership, asking respondents to describe the level of autonomy afforded to trainees in various types of hypospadias repair (distal, midshaft, proximal, perineal) as measured by the Zwisch scale. The Zwisch scale describes the role of the attending in the attending-trainee relationship in a low-to-high trainee autonomy fashion: show and tell; active help; passive help; supervision only. 177 of 761 (23%) unique recipients completed our survey and 174 of 177 (98%) of respondents felt that trainees should not perform hypospadias repair independently in practice without additional fellowship training. Among pediatric urologists who train residents, trainee autonomy as measured by the Zwisch scale decreased as the type of hypospadias repair moved from distal to proximal. There was near unanimous agreement among respondents that urology trainees should not perform hypospadias repair in practice without additional pediatric urology fellowship training, and that current practice affords little trainee autonomy in hypospadias repair at the resident level. These findings introduce a new wrinkle into the issue of trainee autonomy: cases in which trainees perhaps should not have autonomy. Concurrently, the concern with such findings is that this intentional lack of autonomy may extend to other urologic procedures that one would expect trainees to be able to perform independently. Urology trainees are not expected to be able to perform hypospadias in practice without additional training. This raises the question that there may be other such procedures in urology, and if so, should we as instructors, be forthcoming about the limitations of urology residency training to set appropriate trainee expectations?

Pancreatectomía izquierda laparoscópica: ¿la sistematización de la técnica es de utilidad?

Background: Laparoscopic left pancreatectomy is a high complexity procedure that should be systematized to reduce complications and operative time. Objective: To describe the results achieved with a systematized technique for laparoscopic pancreatectomy and splenectomy. Materials and methods: We selected patients who were candidates for distal pancreatectomy and splenectomy between 2007 and 2022. Patients with systemic diseases were excluded. The laparoscopic technique consists of ligating the short vessels as a first step, then dissecting and cutting the splenic artery, leaving the section of the vein as the last surgical gesture to avoid venous congestion of the spleen. Perioperative, intraoperative and postoperative variables were analyzed. Results: A total of 155 patients were analyzed, 90 underwent laparoscopy and 65 underwent conventional surgery. Mean operative time was 168 minutes The operative time in the laparoscopic approach decreased from case 30 onwards. Mortality rate was 1.12%. The incidence of pancreatic fistula was 41%. Need for intraoperative transfusion occurred in 10.7% of the patients and the conversion rate was 13.3%. Conclusion: The systematization of the technique of pancreatic laparoscopy is essential to reduce surgical times, ensure safe dissections and performe more complex procedures.

Safety and efficacy of an ultra low dose fluoroscopic protocol for chronic total occlusion recanalization.

Chronic total occlusion (CTO) revascularization is a major source of radiation for both patients and physicians. Therefore, efforts to minimize radiation during CTOpercutaneous coronary intervention (PCI) are highly encouraged. To evaluate the impact of an Ultra Low fluoroscopic Dose Protocol (ULDP), based on 3.75 frames per second for the fluoroscopy and 7.5 frames per second for the cine acquisition, during CTO PCI. One hundred fiftyconsecutive patients who underwent CTO PCI were retrospectively enrolled. Eighty-fiveunderwent standard dose protocol (SDP) and 65 ULDP. Radiation exposure and acute clinical outcomes were compared between groups. Results were stratified according to lesion complexity. Patients undergoing ULDP, as compared to those undergoing SDP, showed a significant reduction of kerma area product, both for simple lesions (6861.0 vs. 13236.0 mGy × cm2 ; p = 0.014) and complex lesions (CL) (8865.0 vs. 16618.0 mGy × cm2 ; p < 0.001). Similarly, Air Kerma (AK) was lower when ULDP was used (1222.5 vs. 2015.0 cGy in SL, p = 0.134; 1499.0 vs. 2794.0 cGy in CL, p < 0.001). No significant differences were reported regarding procedural success and in-hospital major adverse cardiovascular eventsbetween groups. Notably, there was not any crossover from ULDO to SDP due to poor quality images. Interestingly, fluoroscopy time, procedural time and contrast volume was significantly lower in patients undergoing ULDP only for CLs. ULDP significantly reduces radiation exposure in the setting of high complexity procedures such as CTO PCI. This reduction seemed to be greater with increased procedural complexity and did not impact acute success or adverse clinical events.

Ethnic-Regional Differences in the Allocation of High Complexity Spending in Brazil: Time Analysis 2010-2019.

The following paper presents as a research problem the ethnic-regional differences in the allocation of high complexity spending in Brazil in an analysis from 2010 to 2019. This is a descriptive research in which a generalized linear model (GLM) was developed to analyze these hospital expenditures with high complexity procedures. The total spending on high complexity procedures in Brazil has increased over the past decade. The study shows that the lowest average expenditures are found in the North and Northeast regions. When comparing the spending between different ethnicities, it was observed that the only decrease between the years 2010 and 2019 was in the amount spent on procedures in indigenous people. The spending on male patients was significantly higher compared to female patients. The highest expenditures, on the other hand, are concentrated in the regions of state capitals favoring the strengthening of hub municipalities. Geographic inequalities in access still persist, even with most states already offering almost all procedures. The Brazilian territory is very heterogeneous and needs to organize its health system by regions, therefore integrated public policies and economic and social development are urgently needed.

Facile preparation of superhydrophilic and underwater superoleophobic stainless steel mesh for oil–water separation

Effective oil–water separation is necessary to cope with frequent oil spill accidents, which pose huge risks to the marine ecosystem. Among existing oil–water separation methods, gravitational filtration is the most efficient. When super-wetting materials are used for gravitational filtration, they have the merit of high efficiency but they still have the disadvantages of high price, low eco-friendliness, and complex procedures. To overcome those problems, we fabricated a stainless steel mesh by a one-step method via an annealing process. The annealed mesh achieved both superhydrophilicity and superoleophilicity. For oil–water separation, the annealed mesh, which was pre-wetted by water, demonstrated underwater superoleophobicity. Thus, this study confirmed that the proposed system can separate various oily mixtures with high efficiency (>99 %) and it exhibits underwater anti-oil-fouling.
