RESUMEN

Seaweeds have been studied for their ability to reduce enteric methane emissions of ruminants when fed as a feed supplement. In vivo research with dairy cattle is mainly limited to the seaweed species Ascophyllum nodosum and Asparagopsis taxiformis, whereas in vitro gas production research covers a broader range of brown, red, and green seaweed species from different regions. The objective of the present study was to determine the effect of Chondrus crispus (Rhodophyta), Saccharina latissima (Phaeophyta), and Fucus serratus (Phaeophyta), 3 common northwest European seaweeds, on enteric methane production and lactational performance of dairy cattle. Sixty-four Holstein-Friesian dairy cattle (16 primiparous, 48 multiparous) averaging (mean ± standard deviation) 91 ± 22.6 d in milk and 35.4 ± 8.13 kg/d fat- and protein-corrected milk yield (FPCM) were randomly assigned to 1 of 4 treatments in a randomized complete block design. Cows were fed a partial mixed ration [54.2% grass silage, 20.8% corn silage, and 25.0% concentrate; dry matter (DM) basis] with additional concentrate bait in the milking parlor and the GreenFeed system (C-Lock Inc.). The 4 treatments consisted of a control diet without seaweed supplement (CON), or CON supplemented with 150 g/d (fresh weight of dried seaweed) of either C. crispus (CC), S. latissima (SL), or a 50/50 mix (DM basis) of F. serratus and S. latissima. Milk yield (28.7 vs. 27.5 kg/d, respectively), fat- and protein-corrected milk (FPCM) yield (31.4 vs. 30.2 kg/d, respectively), milk lactose content (4.57 vs. 4.52%, respectively), and lactose yield (1,308 vs. 1,246 g/d, respectively) increased for SL compared with CON. Milk protein content was lower for SL compared with the other treatments. Milk fat and protein contents; yields of fat, protein, lactose, and FPCM; feed efficiency; milk nitrogen efficiency; and somatic cell count did not differ between CON and the other treatments. Depending on week of experiment, milk urea content was higher for SL compared with CON and CC. No effects were observed of the treatments compared with CON for DM intake, number of visits to the GreenFeed, or gas emission (production, yield, or intensity) of CO2, CH4, and H2. In conclusion, the seaweeds evaluated did not decrease enteric CH4 emissions and did not negatively affect feed intake and lactational performance of dairy cattle. Milk yield, FPCM yield, milk lactose content, and lactose yield increased, and milk protein content decreased, with S. latissima.

RESUMEN

The term "Natural Orifice Transluminal Endoscopic Surgery" (NOTES) defines a surgical approach that leverages the body's natural orifices to access the abdominal cavity, presenting a patient-centric perspective by highlighting its potential to eliminate abdominal wall aggression, mitigate postoperative discomfort, and offer benefits comparable to laparoscopic surgery. This comprehensive paper aims to not only review the existing landscape of NOTES techniques but also to propose advancements in flexible tools augmenting established endoscopic platforms, while also exploring the revolutionary concept of robotic structures grounded in micromechatronics and communication technologies. The thorough analysis encompasses the assessment of advantages and limitations associated with flexible devices and robotic platforms, coupled with an in-depth evaluation of the current array of devices used in NOTES, informed by pertinent literature. The authors' comprehensive approach entails scrutinizing technological breakthroughs and offering viable solutions, fostering a comprehensive understanding. Furthermore, the study encompasses an exhaustive evaluation and juxtaposition of state-of-the-art NOTES devices, supplemented by a nuanced discourse on the merits and demerits of flexible devices and robotic platforms, with a focused emphasis on their inherent strengths and weaknesses. Within this context, the discourse extends to strategic suggestions aimed at refining extant designs and cultivating robust, dependable autonomous robotic platforms purpose-built for NOTES. This narrative encapsulates the multifaceted exploration of benefits, challenges, and potential remedies directed towards enhancing prevailing designs and forging a dependable foundation for the future of NOTES.

RESUMEN

OBJECTIVE: The implementation of smokeless tobacco control policies lags behind those for smoking. This scoping review summarizes the studies that evaluated public policies on smokeless tobacco regulation (SLT) and provides an overview of the jurisdictional level, target groups, and policy instruments. METHODS: Seven databases were systematically searched for studies reporting on public policies regulating SLT. Two reviewers independently screened all studies. Data extraction was performed using a predefined extraction form. Extraction was replicated for 10% of the identified studies for quality assurance. A narrative synthesis of the included studies was used to analyze and interpret the data. The protocol was published beforehand with the Open Science Foundation (OSF). RESULTS: Fourty articles comprising 41 studies were included. Most of the studies reported in the articles were conducted in the United States (n = 17) or India (n = 14). Most studies reported outcomes for students (n = 8), retailers/sellers (n = 8), and users/former users (n = 5). The impact of public policies on smokeless tobacco use, in general, was most frequently assessed (n = 9), followed by the impact of taxes (n = 7), product bans (n = 6), sales/advertising bans near educational institutions (n = 4), and health warnings (n = 3) on consumer behavior. CONCLUSIONS: There are significant gaps in the evaluation of smokeless tobacco regulation studies that need to be filled by further research to understand the observed outcomes. WHO reporting on Framework Convention on Tobacco Control (FCTC) implementation should be linked to studies evaluating smokeless tobacco control measures at all levels of jurisdictions and in countries not members of the WHO FCTC or do not provide data. IMPLICATION: Large gaps in the evaluation of SLT control policies exist. For some countries, WHO FCTC evaluations are available for different levels of jurisdictions. In countries with a strong federal structure, there is a lack of data beyond the national level to provide a more detailed look at compliance, indirect effects, or implementation gaps. More research is needed at all levels of jurisdictions, which add to the work of the WHO to understand what works for which target group, how the different levels of jurisdiction interact, how the real-world context can be incorporated, and what indirect effects may occur.

RESUMEN

OBJECTIVES: Given the growing interest worldwide in applying public policies to improve human health, we undertook a systematic review of studies investigating whether public policies targeting unhealthy products could reduce cardiovascular diseases. STUDY DESIGN: This study was a systematic review of the literature. METHODS: We searched research studies published in 2000-2020 from major databases, including MEDLINE and Embase. We followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and narratively synthesized the studies based on vote counting and direction of the intervention effect. RESULTS: Ninety-eight studies, mostly from high-income countries, met the inclusion criteria. Most studies were on public policies targeting sugar-sweetened beverages and tobacco, followed by alcohol, sugar, salt, and junk foods. Overall, many reported that several fiscal, regulatory, and educational policies generated beneficial effects of reducing the diseases. Those studies that reported no or limited effects highlighted several sociodemographic and health risk characteristics and design and implementation aspects of the policy interventions as factors limiting the policy effects; most of these are modifiable with appropriate policy interventions. For instance, low magnitude of tax, substitution with other unhealthy products, firms' competitive response strategies, pre-existence of smoking bans, incremental enactment of smoking regulations, degree of enforcement, and various sociocultural factors minimized the effects of the policies. CONCLUSION: The literature supports a growing consensus on the beneficial effects of public policy for improving human health. The design and implementation of public policies must address various impeding factors and incorporate appropriate remedial measures. Further research is needed from low- and middle-income countries and on whether and how multiple policy instruments work in tandem.

RESUMEN

OBJECTIVE: To investigate patient perspective of telephone consultations (TCs) in gynaecology and identify which patients benefit most from a telemedicine system. DESIGN: Service evaluation. SETTING: Gynaecology outpatient services at a tertiary referral hospital. POPULATION: Patients who received a TC during May and June 2020. METHODS: Postal questionnaire combining three validated tools: QQ-10, Patient Enablement Index (PEI) and National Health Service Friends and Family Test (NHS-FFT). Quantitative data and free text responses were analysed. MAIN OUTCOME MEASURES: Responses to QQ-10, PEI and NHS-FFT. RESULTS: In total, 1307 patients were contacted and 504 patients responded (39%). Most (89%) described their experience as 'Very good' or 'Good' (NHS-FFT). Positive themes from responses included 'convenience', 'effectiveness' and 'equivalent care'. QQ-10 responses demonstrated a high Value score of 79 (0-100) and a low Burden score of 15. PEI scores suggested that most patients felt better or much better able to understand and cope with their condition following TC. The majority of patients (77%) would 'Strongly agree' or 'Mostly agree' to a repeat TC. Regarding patient outcomes, 21% were discharged and 71% required follow up. Menopause, fertility and endometriosis follow-up clinic patients benefited most from TC. Gynaecology-oncology patients found TC least acceptable. CONCLUSION: We report a large questionnaire survey of patient experience of TC in gynaecology. Telemedicine is convenient, acceptable and effective for conducting care in selected groups. TC can support patients in communicating intimate symptoms. TWEETABLE ABSTRACT: Telephone consultations are a convenient, acceptable and effective medium for conducting patient care in gynaecology.

RESUMEN

Dental public health in action: foundation dentists' delivery of an oral health promotion outreach project for people experiencing homelessness in London.Within a decade, the UK has seen a dramatic increase in homelessness. This is defined as being without an available home that could reasonably be occupied. The increase has been driven by increasing poverty, welfare reform, cuts to public services and lack of affordable housing (Bramley et al., 2015; Fitzpatrick et al., 2013; Fitzpatrick et al., 2018). Rough sleeping in England alone has increased by 2,909 people or 165% since 2010 (Ministry of Housing, Communities and Local Government, 2018). This increase has been particularly visible in London (National Audit Office, 2018), where approximately a quarter of the country's rough sleepers reside (Ministry of Housing, Communities and Local Government, 2018).

RESUMEN

A compartmental model is proposed to predict the coronavirus 2019 (Covid-19) spread. It considers: detected and undetected infected populations, social sequestration, release from sequestration, plus reinfection. This model, consisting of seven coupled equations, has eight coefficients which are evaluated by fitting data for eight US states that make up 43% of the US population. The evolution of Covid-19 is fairly similar among the states: variations in contact and undetected recovery rates remain below 5%; however, variations are larger in recovery rate, death rate, reinfection rate, sequestration adherence and release rate from sequestration. Projections based on the current situation indicate that Covid-19 will become endemic. If lockdowns had been kept in place, the number of deaths would most likely have been significantly lower in states that opened up. Additionally, we predict that decreasing contact rate by 10%, or increasing testing by approximately 15%, or doubling lockdown compliance (from the current ~15% to ~30%) will eradicate infections in Texas within a year. Extending our fits for all of the US states, we predict about 11 million total infections (including undetected), and 8 million cumulative confirmed cases by 1 November 2020.

RESUMEN

BACKGROUND: Appropriate utilization of therapeutic agents is a basic component of the quality of health outcomes for the patients and the community. A pilot study was conducted to evaluate the rational use of medicines and antibiotics, based on World Health Organization (who) prescribing indicators. STUDY DESIGN: We performed a retrospective, descriptive, cross-sectional pilot study in the medical outpatient departments in four tertiary care hospitals of Islamabad, Pakistan, in order to verify the correct prescribing of medicines according to the validated indicators prepared by the World Health Organization (who). METHODS: The Registries of all the prescriptions formulated during the period April 02 2017 - April 01 2018 by the outpatient departments of four tertiary care hospitals (two government funded hospitals (GH-A and GH-B) and two private funded hospitals (PH-C and PH-D) were considered. According to the World Health Organization recommendations, during the following month (April 02 2018 to May 1 2018), 600 prescriptions (150 per hospital) were collected by a random sampling method, verified and analyzed through a statistical tool (SPSS version 22.0). RESULTS: Mean number of medicines per prescription were 4.6 (Optimal value ≤ 2), with the highest value observed in GH-B hospital. Out of these, 350 (58.3%) (Optimal value < 30%) prescriptions consisted of antibiotics and 340 (56.6%) (Optimal value < 25%) prescriptions consisted of injectable medicines, with marked differences between hospitals. About 550 (19.6%) medicines were prescribed by generic name in all selected prescriptions with the lowest value observed in PH-D (9.9%) (Optimal value = 100%). Overall, 88% medicines were prescribed from National essential medicine list/formulary (Optimal value = 100%). All the prescribing core indicators showed significant difference between hospitals (P = 0.001). The most commonly prescribed antibiotic was ceftriaxone (37.4%), followed by ciprofloxacin (15.1%). CONCLUSIONS: Poor adherence to WHO prescribing indicators were observed in all medical outpatient departments in selected hospitals. WHO recommended core interventions should be implemented on trial basis to develop strategies to achieve long-lasting benefits.

RESUMEN

INTRODUCTION: Fluid therapy in critically ill patients, especially timing and fluid choice, is controversial. Previous randomized trials produced conflicting results. This observational study evaluated the effect of colloid use on 90-day mortality and acute kidney injury (RIFLE F) within the Rational Fluid Therapy in Asia (RaFTA) registry in intensive care units. MATERIALS AND METHODS: RaFTA is a prospective, observational study in Asian intensive care unit (ICU) patients focusing on fluid therapy and related outcomes. Logistic regression was performed to identify risk factors for increased 90-day mortality and acute kidney injury (AKI). RESULTS: Twenty-four study centers joined the RaFTA registry and collected 3,187 patient data sets from November 2011 to September 2012. A follow-up was done 90 days after ICU admission. For 90-day mortality, significant risk factors in the overall population were sepsis at admission (OR 2.185 [1.799; 2.654], p < 0.001), cumulative fluid balance (OR 1.032 [1.018; 1.047], p < 0.001), and the use of vasopressors (OR 3.409 [2.694; 4.312], p < 0.001). The use of colloids was associated with a reduced risk of 90-day mortality (OR 0.655 [0.478; 0.900], p = 0.009). The initial colloid dose was not associated with an increased risk for AKI (OR 1.094 [0.754; 1.588], p = 0.635). CONCLUSION: RaFTA adds the important finding that colloid use was not associated with increased 90-day mortality or AKI after adjustment for baseline patient condition. CLINICAL SIGNIFICANCE: Early resuscitation with colloids showed potential mortality benefit in the present analysis. Elucidating these findings may be an approach for future research.

RESUMEN

Higher mortality following admission to hospital at the weekend has been reported for several conditions. It is unclear whether this variation is due to differences in patients or their care. Status epilepticus mandates hospital admission and usually critical care: its study might provide new insights into the nature of any weekend effect. We studied 20,922 adults admitted to UK critical care with status epilepticus from 2010 to 2015. We used multiple logistic regression to evaluate the association between weekend admission and in-hospital mortality, comparing university hospitals with other hospitals. There were 2462 in-hospital deaths (12%). There was no difference in mortality after weekend admission to university hospitals, adjusted odds ratio (95%CI) 0.99 (0.84-1.16), p = 0.89. Mortality was less after weekend admission than after admissions Monday to Friday in hospitals not associated with a university, adjusted odds ratio (95%CI) 0.74 (0.64-0.87), p = 0.0001. There is no evidence that adults admitted to UK critical care at the weekend in status epilepticus are more likely to die than similar patients admitted during the week.

RESUMEN

Social media provides a useful platform for informal discussions about healthcare. Acceptability is key to the uptake of diagnostic devices and this can be difficult to gauge from questionnaires and qualitative studies. The aim of this study is to investigate whether Facebook could be used to gauge public perception toward uptake of a new diagnostic test for Barrett's esophagus called the Cytosponge. We retrospectively reviewed Facebook comments relating to a video on the Cytosponge. We categorized comments into: (1) Positive, (2) Negative, (3) Unknown and (4) Questions. Recurring themes that arose were compared to a qualitative study on the Cytosponge. The video received 22.5 million views and 2837 comments within four months. Of these, 525 comments were positive, 215 were unknown, 179 were negative, 71 were questions, and 1847 were 'Tagged' comments. Among positive comments, recurrent themes were that it was innovative, could lead to early cancer-detection, and more favorable than endoscopy. Among negative comments, a recurring theme was concern about the risk of gagging and vomiting. Among 'questions', a recurring theme was related to the risk of Cytosponge detachment. We compared our analysis to a published qualitative study and found similar themes arose across both studies. Facebook provides a rich source of qualitative data, which could be used to augment studies to gauge public perception toward a new diagnostic test.

RESUMEN

PURPOSE: Antithyroid drug (ATD)-induced agranulocytosis is a rare but life-threatening adverse drug reaction that occurs in patients during the treatment of Graves' disease. We aimed to comprehensively examine data for patients with this rare complication and to improve the clinical safety of ATDs. METHODS: We retrospectively reviewed the medical records of 64 hospitalized patients diagnosed with ATD-induced agranulocytosis between 2000 and 2015. RESULTS: Agranulocytosis occurred in 52 (81.3%) patients within the first 3 months after initiation of ATD therapy. Fever (84.4%) and sore throat (82.8%) were the most common symptoms. Although they experienced symptoms, 30 (46.9%) patients did not seek treatment immediately and delayed their diagnosis of agranulocytosis. The minimum granulocyte count was lower in the patients diagnosed after the appearance of symptoms than in those diagnosed before the appearance of symptoms (0.01 × 109/L (0 × 109/L - 0.06 × 109/L) versus 0.26 × 109/L (0.05 × 109/L - 0.40 × 109/L), P < 0.001). The interval days from the appearance of symptoms to the diagnosis of agranulocytosis were negatively correlated with the minimum granulocyte count (r = -0.348, P = 0.005). In addition, a lower minimum granulocyte count was associated with a longer recovery time (ß = -11.899, 95% CI -15.304 to -8.496). CONCLUSIONS: Our findings have demonstrated that delayed diagnosis of ATD-induced agranulocytosis is common in our population. Delayed diagnosis is associated with severe agranulocytosis and may prolong the recovery time from agranulocytosis. Monitoring of the white blood cell and granulocyte counts may be an effective way to establish an early diagnosis and prevent progression to severe agranulocytosis.

RESUMEN

The present study was conducted to appraise the ontogenic radio-sensitivity of a serious tropical pest, Spodoptera litura (Fabr.). The molecular responses pertaining to the phenoloxidase (PO) pathway and an anti-oxidant defense mechanism were evaluated in order to understand its implication in pest control at pre-harvest and post-harvest intervals. Irradiation exhibited an inverse relationship with age with respect to impact on developmental and transcriptional responses. Transcript abundance of PO cascade enzymes, prophenoloxidase (slppo-2), its activating enzyme (slppae-1) and free-radical scavenging enzymes, superoxide dismutase (slsod) and catalase (slcat) was evaluated upon gamma irradiation alone and the dual-stress of radiation plus microbial challenge. The slppo-2, slppae-1, slsod and slcat transcripts were significantly up-regulated in F 1 L6 larvae (6th-instar) resulting from 100 Gy sub-sterilized male adults and unirradiated female moths. The extent of upregulation was relatively higher in comparison with L6 survivors (6th-instar larvae) developed from irradiated neonates (L1) treated with 100 Gy. Upon Photorhabdus challenge, the transcripts were down-regulated in irradiated L1 suggesting increased larval susceptibility to bacterial infections. Radioresistance increased with the age of the insect, and molecular responses (transcript abundance) of insect defense mechanism were less influenced when older age (F 1 progeny) were irradiated. These findings will help to optimize the gamma dose to be employed in inherited sterility technique for (pre-harvest) pest suppression and (post-harvest) phytosanitation and quarantine, and suggest compatible integration of biorational tactics including nuclear technology.

RESUMEN

OBJECTIVES: Coffee is one of the most popular and consumable drinks worldwide. However, there are conflicting results on the influence of this drink in oral and pharyngeal cancer risk. To clarify this, we aimed to systemically review and carry out a meta-analysis of the relevant literature on the association between coffee and oral and pharyngeal cancer. STUDY DESIGN: We carried out an electronic search of publications up to August 2016 from PubMed, National Library of Medicines Medline, Embase, Science Direct and the Cochrane Central Register. The Newcastle-Ottawa scale was used to address the quality of the studies a meta-analysis was carried out using random-effects models. RESULTS: From the 22,515 entries identified in the search, 13 case-control and 4 cohort studies were selected. With regards to quality on the Newcastle-Ottawa scale, an overall value of 6.06 was obtained. The analysis for oral and pharyngeal cancer grouped together indicated a pooled OR of .69 (95% CI of .57-.84; p<.001) for high versus low coffee consumption with a moderate heterogeneity (I2: 50.3%; p=.009). Regarding studies on oral cavity cancers we observed a pooled OR of 0.82; 95% CI =.58-1.16; p=.257) and for pharyngeal cancers a pooled OR of .72 (95% CI of 0.54-.95; p=.019). There was no significant publication bias. CONCLUSION: The results show an inverse association between high coffee consumption and the risk of oral and pharyngeal cancers, which indicates that coffee may have a protective role against these cancers. Further larger prospective observational cohort studies are needed to address any effect of other possible co-factors.

RESUMEN

Mortality and morbidity was assessed after adoption of a systematic care for patient with pancreatoduodenectomy starting from patient selection and preparation, operative technique, and postoperative care. In this prospective study seventy patients who underwent pancreatoduodenectomy for periampullary carcinoma with curative intent between January 2010 and December 2014 were carefully analyzed prospectively. Patients were selected those who had ampullary carcinoma, lower bile duct carcinoma and small size carcinoma head of pancreas without local invasion and distant metastasis, and the patient who did not have any major disabling comorbid diseases. All patients were assessed uniformly before surgery and deficiency were corrected up to normal level before operation. Pancreatoduodenectomy and standard lymphadenectomy was performed meticulously with minimum blood loss. The pancreatojejunal reconstruction was performed using duct-to-mucosa method mostly. A nasojejunal feeding tube was placed in most patients for starting postoperative early oral feeding. Broad spectrum antibiotics and the epidural analgesia were mostly prescribed for good control infection and pain. Proper nutrition was maintained in calculative way through central venous line and nasojejunal feeding tube in the early postoperative period. General care, early mobilization and chest physiotherapy were given routinely in each patient. Seventy-seven percent (n=54) patients did not have any postoperative complications and they were discharged from hospital within 12-14 postoperative days. The morbidity occurred in 16 patients (23%) and most common complication was wound infection (18%, n=9). The rest complications were pancreatojejunal anastomotic leakage - 2, hepaticojejunal anastomosis leakage - 1, melaena - 1, intra-abdominal abscess - 1, intra-abdominal hemorrhage - 1, and renal dysfunction - 1. The mortality rate was 5.7% (n=4), causes of death were massive myocardial infarction; 1, failure of reversal from anesthesia; 1, massive intraabdominal bleeding; 1 and CV catheter related severe sepsis; 1. Review of recent published literature revealed that mortality and morbidity our series is better than low volume center and almost similar with high volume center of pancreatoduodenectomy surgery. Our systematic management policy of careful patient selection, planned approach in the form of proper work up, meticulous conduction of the procedure, appropriate postoperative care provides an acceptable morbidity and mortality after pancreatoduodenectomy.

RESUMEN

Tuberculosis (TB) isolated in Common Bile Duct (CBD) is very rare and its treatment is somewhat controversial. We report a case of distal CBD tuberculosis diagnosed as cholangiocarcinoma. A 40 year old man presented with obstructive jaundice without abdominal pain, fever or weight loss. Ultrasonography and Magnetic Resonance Cholangio-Pancreatography (MRCP) indicated a mass lesion in the Distal CBD, which caused structure of the distal common bile duct. As Cholangiocarcinoma was suspected, he underwent Whipple procedure (pancreaticoduodenectomy). Histological examination of resected specimen revealed typical features of tuberculosis in the distal CBD, pancreatic head and lymph nodes. The rest of the abdominal cavity was unremarkable. Anti-microbial therapy for tuberculosis is started for 12 month course and he is well.

RESUMEN

Toll-like receptors (TLRs) are key players in maintaining protection against any invading pathogen. These molecules are microbial sensing proteins which detect pathogen-associated molecular patterns and induce the body's innate immune system to elicit a response against invading pathogens. In addition to their role in pathogen recognition and elimination, these proteins are highly important in cancer biology and also play a variety of roles in normal to cancerous transformation or its prevention. There is much published literature on the role of TLRs in pathogen recognition and elimination, but recently the number of articles relevant to the role of TLR in carcinogenesis has increased due to their importance in this area. On the one hand, they are involved in microbial elimination and, on the other hand, their modulation during cancer development has several implications. Accumulating a diverse thread of cancer-associated TLR modulation and infection susceptibility has several caveats. Some cancer-associated TLR modulation increases susceptibility to particular infections, while increased expression of certain TLR was found to help in the carcinogenic process through inducing inflammation. This article concludes that clinicians should consider TLR modulation during infection risk assessment in cancer patients. These modulations should also be considered while designing management strategies against cancer and its associated infections.

RESUMEN

BACKGROUND: Since the early 2000s, treatment options for multiple myeloma have rapidly expanded, adding significant complexity to the management of this disease. To our knowledge, no systematic qualitative research on clinical decision-making in multiple myeloma has been published. We sought to characterize how physicians view and implement guidelines and incorporate novel approaches into patient care. METHODS: We designed a semi-structured qualitative interview guide informed by literature review and an expert advisory panel. We conducted 60-minute interviews with a diverse sample of oncology physicians in the southeast United States. We used a constant comparative method to code and analyze interview transcripts. The research team and advisory panel discussed and validated emergent themes. RESULTS: Participants were 13 oncologists representing 5 academic and 4 community practices. Academic physicians reported using formal risk-stratification schemas; community physicians typically did not. Physicians also described differences in eligibility criteria for transplantation; community physicians emphasized distance, social support, and psychosocial capacity in making decisions about transplantation referral; the academic physicians reported using more specific clinical criteria. All physicians reported using a maintenance strategy both for post-transplant and for transplant-ineligible patients; however, determining the timing of maintenance therapy initiation and the response were reported as challenging, as was recognition or definition of relapse, especially in terms of when treatment re-initiation is indicated. CONCLUSIONS: Practices reported by both academic and community physicians suggest opportunities for interventions to improve patient care and outcomes through optimal multiple myeloma management and therapy selection. Community physicians in particular might benefit from targeted education interventions about risk stratification, transplant eligibility, and novel therapies.

RESUMEN

BACKGROUND: The English National Training Programme for Laparoscopic Colorectal Surgery introduced a validated objective competency assessment tool to accredit surgeons before independent practice. The aim of this study was to determine whether this technical skills assessment predicted clinical outcomes. METHODS: Established consultants, training in laparoscopic colorectal surgery, were asked to submit two operative videos for evaluation by two blinded assessors using the competency assessment tool. A mark of 2·7 or above was considered a pass. Clinical and oncological outcomes were compared above and below this mark, including regression analysis. RESULTS: Eighty-five consultant surgeons submitted 171 videos. Of these, 44 (25·7 per cent) were in the fail group (score less than 2·7). This low scoring group had more postoperative morbidity (25 versus 8·7 per cent; P = 0·005), including surgical complications (18 versus 6·3 per cent; P = 0·020) and fewer lymph nodes harvested (median 13 versus 18; P = 0·004). A score of less than 2·7 was an independent predictor of surgical complication, lymph node yield and distal resection margin clearance. Consultants with higher scores had performed similar numbers of laparoscopic colorectal operations (median 37 versus 40; P = 0·373) but more structured training operations (18 versus 9; P < 0·001). CONCLUSION: An objective technical skills assessment provided a discriminatory tool with which to accredit laparoscopic colorectal surgeons.

RESUMEN

BACKGROUND: The splintering of general surgery into subspecialties in the past decade has brought into question the relevance of a continued emphasis on traditional general surgical training. With the majority of trainees now expressing a preference to subspecialise early, this study sought to identify if the requirement for proficiency in managing general surgical conditions has reduced over the past decade through comparison of general and specialty surgical admissions at a tertiary referral center. METHODS: A cross-sectional review of all surgical admissions at Cork University Hospital was performed at three individual time points: 2002, 2007 & 2012. Basic demographic details of both elective & emergency admissions were tabulated & analysed. Categorisation of admissions into specialty relevant or general surgery was made using International guidelines. RESULTS: 11,288 surgical admissions were recorded (2002:2773, 2007:3498 & 2012:5017), showing an increase of 81 % over the 10-year period. While growth in overall service provision was seen, the practice of general versus specialty relevant emergency surgery showed no statistically significant change in practice from 2002 to 2012 (p = 0.87). General surgery was mostly practiced in the emergency setting (84 % of all emergency admissions in 2012) with only 28 % elective admissions for general surgery. A reduction in length of stay was seen in both elective (3.62-2.58 bed days, p = 0.342) & emergency admissions (7.36-5.65, p = 0.026). CONCLUSIONS: General surgical emergency work continues to constitute a major part of the specialists practice. These results emphasize the importance of general surgical training even for those trainees committed to sub-specialisation.
