Improved Early Cleft Lip and Palate Complications at a Surgery Specialty Center in the Developing World.

OBJECTIVE: To evaluate complication rates following cleft lip and cleft palate repairs during the transition from mission-based care to center-based care in a developing region. PATIENTS AND DESIGN: We performed a retrospective review of 3419 patients who underwent cleft lip repair and 1728 patients who underwent cleft palate repair in Guwahati, India between December 2010 and February 2014. Of those who underwent cleft lip repair, 654 were treated during a surgical mission and 2765 were treated at a permanent center. Of those who underwent cleft palate repair, 236 were treated during a surgical mission and 1491 were treated at a permanent center. SETTING: Two large surgical missions to Guwahati, India, and the Guwahati Comprehensive Cleft Care Center (GCCCC) in Assam, India. MAIN OUTCOME MEASURE: Overall complication rates following cleft lip and cleft palate repair. RESULTS: Overall complication rates following cleft lip repair were 13.2% for the first mission, 6.7% for the second mission, and 4.0% at GCCCC. Overall complication rates following cleft palate repair were 28.0% for the first mission, 30.0% for the second mission, and 15.8% at GCCCC. Complication rates following cleft palate repair by the subset of surgeons permanently based at GCCCC (7.2%) were lower than visiting surgeons ( P < .05). CONCLUSIONS: Our findings support the notion that transitioning from a mission-based model to a permanent facility-based model of cleft care delivery in the developing world can lead to decreased complication rates.

Does left ventricular hypertrophy affect cognition and brain structural integrity in type 2 diabetes? Study design and rationale of the Diabetes and Dementia (D2) study.

BACKGROUND: Cognitive impairment is common in type 2 diabetes mellitus, and there is a strong association between type 2 diabetes and Alzheimer's disease. However, we do not know which type 2 diabetes patients will dement or which biomarkers predict cognitive decline. Left ventricular hypertrophy (LVH) is potentially such a marker. LVH is highly prevalent in type 2 diabetes and is a strong, independent predictor of cardiovascular events. To date, no studies have investigated the association between LVH and cognitive decline in type 2 diabetes. The Diabetes and Dementia (D2) study is designed to establish whether patients with type 2 diabetes and LVH have increased rates of brain atrophy and cognitive decline. METHODS: The D2 study is a single centre, observational, longitudinal case control study that will follow 168 adult patients aged >50 years with type 2 diabetes: 50% with LVH (case) and 50% without LVH (control). It will assess change in cardiovascular risk, brain imaging and neuropsychological testing between two time-points, baseline (0 months) and 24 months. The primary outcome is brain volume change at 24 months. The co-primary outcome is the presence of cognitive decline at 24 months. The secondary outcome is change in left ventricular mass associated with brain atrophy and cognitive decline at 24 months. DISCUSSION: The D2 study will test the hypothesis that patients with type 2 diabetes and LVH will exhibit greater brain atrophy than those without LVH. An understanding of whether LVH contributes to cognitive decline, and in which patients, will allow us to identify patients at particular risk.

Primary Cleft Lip and Palate Repair in Assam, India: Does Preoperative Anthropometric Analysis Help Identify Patients With Increased Surgical Risk in a Clinically Prescreened Population?

OBJECTIVE: To compare anthropometric z-scores with incidence of post-operative complications for patients undergoing primary cleft lip or palate repair. DESIGN: This was a retrospective observational analysis of patients from a surgical center in Assam, India, and includes a cohort from a single surgical mission completed before the opening of the center. SETTING: Patients included in the study underwent surgery during an Operation Smile mission before the opening of Operation Smile's Guwahati Comprehensive Cleft Care Center in Guwahati, India. The remaining cohort received treatment at the center. All patients received preoperative assessment and screening; surgery; and postoperative care, education, and follow-up. PATIENTS, PARTICIPANTS: Our sample size included 1941 patients and consisted of all patients with complete information in the database who returned for follow-up after receiving primary cleft lip repair or primary cleft palate repair between January 2011 and April 2013. INTERVENTIONS: Preoperative anthropometric measurements. MAIN OUTCOME MEASURE(S): Postoperative complications. RESULTS: Anthropometric z-scores were not a significant predictor of adverse surgical outcomes in the group analyzed. Palate surgery had increased risk of complication versus lip repair, with an overall odds ratio of 5.66 (P < .001) for all patients aged 3 to 228 months. CONCLUSIONS: Anthropometric z-scores were not correlated with increased risk of surgical complications, possibly because patients were well screened for malnutrition before surgery at this center. Primary palate repair is associated with an approximate fivefold increased risk of developing postoperative complication(s) compared with primary lip repair.

Sun protection for preventing basal cell and squamous cell skin cancers.

BACKGROUND: 'Keratinocyte cancer' is now the preferred term for the most commonly identified skin cancers basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC), which were previously commonly categorised as non-melanoma skin cancers (NMSC). Keratinocyte cancer (KC) represents about 95% of malignant skin tumours. Lifestyle changes have led to increased exposure to the sun, which has, in turn, led to a significant increase of new cases of KC, with a worldwide annual incidence of between 3% and 8%. The successful use of preventive measures could mean a significant reduction in the resources used by health systems, compared with the high cost of the treatment of these conditions. At present, there is no information about the quality of the evidence for the use of these sun protection strategies with an assessment of their benefits and risks. OBJECTIVES: To assess the effects of sun protection strategies (i.e. sunscreen and barrier methods) for preventing keratinocyte cancer (that is, basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC) of the skin) in the general population. SEARCH METHODS: We searched the following databases up to May 2016: the Cochrane Skin Group Specialised Register, CENTRAL, MEDLINE, Embase, and LILACS. We also searched five trial registries and the bibliographies of included studies for further references to relevant trials. SELECTION CRITERIA: We included randomised controlled clinical trials (RCTs) of preventive strategies for keratinocyte cancer, such as physical barriers and sunscreens, in the general population (children and adults), which may provide information about benefits and adverse events related to the use of solar protection measures. We did not include trials focused on educational strategies to prevent KC or preventive strategies in high-risk groups. Our prespecified primary outcomes were BCC or cSCC confirmed clinically or by histopathology at any follow-up and adverse events. DATA COLLECTION AND ANALYSIS: Two review authors independently selected studies for eligibility using Early Review Organizing Software (EROS). Similarly, two review authors independently used predesigned data collection forms to extract information from the original study reports about the participants, methods of randomisation, blinding, comparisons of interest, number of participants originally randomised by arm, follow-up losses, and outcomes, and they assessed the risk of bias. We resolved any disagreement by consulting a third author and contacted trial investigators of identified trials to obtain additional information. We used standard methodological procedures expected by Cochrane. MAIN RESULTS: We included one RCT (factorial design) that randomised 1621 participants.This study compared the daily application of sunscreen compared with discretionary use of sunscreen, with or without beta-carotene administration, in the general population. The study was undertaken in Australia; 55.2% of participants had fair skin, and they were monitored for 4.5 years for new cases of BCC or cSCC assessed by histopathology. We found this study to be at low risk of bias for domains such as allocation, blinding, and incomplete outcome data. However, we found multiple unclear risks related to other biases, including an unclear assessment of possible interactions between the effects of the different interventions evaluated (that is, sunscreen and beta-carotene). We found no difference in terms of the number of participants developing BCC (n = 1621; risk ratio (RR) 1.03, 95% confidence interval (CI) 0.74 to 1.43) or cSCC (n = 1621; RR 0.88, 95% CI 0.50 to 1.54) when comparing daily application of sunscreen with discretionary use, even when analyses were restricted to groups without beta-carotene supplementation. This evidence was of low quality, which means that there is some certainty that future studies may alter our confidence in this evidence.We reported adverse events in a narrative way and included skin irritation or contact allergy.We identified no studies that evaluated other sun protection measures, such as the use of sun-protective clothing, sunglasses, or hats, or seeking the shade when outdoors. AUTHORS' CONCLUSIONS: In this review, we assessed the effect of solar protection in preventing the occurrence of new cases of keratinocyte cancer. We only found one study that was suitable for inclusion. This was a study of sunscreens, so we were unable to assess any other forms of sun protection. The study addressed our prespecified primary outcomes, but not most of our secondary outcomes. We were unable to demonstrate from the available evidence whether sunscreen was effective for the prevention of basal cell carcinoma (BCC) or cutaneous squamous cell carcinoma (cSCC).Our certainty in the evidence was low because there was a lack of histopathological confirmation of BCC or cSCC in a significant percentage of cases. Amongst other sources of bias, it was not clear whether the study authors had assessed any interaction effects between the sunscreen and beta-carotene interventions. We think that further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate.

Terpenes and terpenoids in chemical sensitivity.

UNLABELLED: CONTEXT : Terpenes and terpenoids are a diverse class of organic compounds produced by a variety of plants, particularly conifers. Chemically sensitive patients can be targeted by terpenes and terpenoids, resulting in a triggering of symptoms and pathology. Often patients cannot clear their symptoms from exposure to chemicals unless terpenes and terpenoids are avoided and neutralized along with chemical avoidance and treatment. OBJECTIVE: This article evaluates the presence, diagnosis, and treatment of terpenes exposure in chemically sensitive patients. DESIGN: A double-blind, placebo-controlled, 2-part study was designed to establish the chemically sensitive state of the patients in part 1, followed by a second set of challenges to determine each patient's concurrent sensitivity to terpenes and terpenoids in part 2. In all of the challenges, normal saline was used as a control. A case report illustrates the history of 1 patient and describes the authors' treatment methods. SETTING: The study was developed and conducted at the Environmental Health Center of Dallas (EHC-D) because the environment within the center is 5 times less polluted than the surrounding environments, as determined by quantitative air analysis and particulate counts. PARTICIPANTS: A total of 45 chemically sensitive patients at EHC-D with odor sensitivity to terpenes. The cohort included 18 males and 27 females, aged 24-62 y.Intervention • Patients were deadapted (4 d) and evaluated in a 5-times-less-polluted environment, which was evaluated using air analysis and particulate counts. After deadaptation, the patients were challenged by inhalation in a controlled, less-polluted glass steel booth inside an environmentally controlled room with an ambient air dose of the toxics in the order of parts per billion (PPB) and parts per million (PPM). These toxics included formaldehyde, pesticide, cigarette smoke, ethanol, phenol, chlorine, new sprint, perfume, and placebo. They were also challenged intradermally with extracts of volatile organic compounds (VOCs), including formaldehyde, orris root, ethanol, phenol, cigarette smoke, chlorine, newsprint, perfume, terpenes, terpenoids, and placebo. OUTCOME MEASURES: Inhaled challenges recorded pulse, blood pressure, peak bronchial flow, and other signs and symptoms 30 min before and at 15-min intervals for 2 h postchallenge. Intradermal challenges recorded wheal size and the provocation of signs and symptoms. RESULTS : Different numbers of patients were tested for each terpenes source because of time-related factors or the cumulative effect of testing, which made patients unable to continue. Of 45 chemically sensitive patients in the study, 43 demonstrated sensitivity to terpenes. CONCLUSIONS: This particular patient group was positive for a number of toxic and nontoxic chemicals provoking their symptoms. This study shows there was a connection between VOCs, other chemicals, and terpenes in chemically sensitive patients in a prospective cohort study. It has also shown the potential for terpenes to exacerbate symptoms of chemical sensitivity. Further research on this topic is recommended.

Limited Chances of Speech Improvement After Late Cleft Palate Repair.

Late primary palatal repair is a common phenomenon, and many patients across the world will be operated on at a far later age than is suggested for normal speech development. Nevertheless, little is known about the speech outcomes after these procedures and conflicting results exist among the few studies performed. In this study, blinded preoperative and postoperative speech recordings from 31 patients operated on at Guwahati Comprehensive Cleft Care Center in Assam, India, older than 7 years were evaluated. Six non-Indian speech and language pathologists evaluated hypernasal resonance and articulation, and 4 local laymen evaluated the speech intelligibility/acceptability of the samples. In 25 of 31 cases, the evaluators could not detect any speech improvement in the postoperative recordings. A clear trend of postoperative improvement was only found in 6 of the 31 patients. Among these 6 patients, lesser clefts were overrepresented. Our findings together with previous studies suggest that late palate repairs have the potential to improve speech, but the probability for improvement and degree of improvement is low, especially in older adolescents and adults with complete clefts.

Speech and Speech-Related Quality of Life After Late Palate Repair: A Patient's Perspective.

Many patients with cleft palate deformities worldwide receive treatment at a later age than is recommended for normal speech to develop. The outcomes after late palate repairs in terms of speech and quality of life (QOL) still remain largely unstudied. In the current study, questionnaires were used to assess the patients' perception of speech and QOL before and after primary palate repair. All of the patients were operated at a cleft center in northeast India and had a cleft palate with a normal lip or with a cleft lip that had been previously repaired. A total of 134 patients (7-35 years) were interviewed preoperatively and 46 patients (7-32 years) were assessed in the postoperative survey. The survey showed that scores based on the speech handicap index, concerning speech and speech-related QOL, did not improve postoperatively. In fact, the questionnaires indicated that the speech became more unpredictable (P < 0.01) and that nasal regurgitation became worse (P < 0.01) for some patients after surgery. A total of 78% of the patients were still satisfied with the surgery and all of the patients reported that their self-confidence had improved after the operation. Thus, the majority of interviewed patients who underwent late primary palate repair were satisfied with the surgery. At the same time, speech and speech-related QOL did not improve according to the speech handicap index-based survey. Speech predictability may even become worse and nasal regurgitation may increase after late palate repair, according to these results.

Lessons learned from two consecutive cleft lip and palate missions and the impact of patient education.

Two consecutive cleft missions were conducted in Guwahati, northeastern India in December 2010 and January 2011. In the later mission, a standardized patient education program for postoperative care was introduced. The objective of this study was to retrospectively evaluate the impact of the patient education program on cleft lip complications in terms of wound infection and dehiscence. Two hundred ninety-eight cleft lip repairs were performed in the first mission and 220 (74%) returned for early follow-up. In the second mission, 356 patients were operated on and 252 (71%) returned for follow-up. From the first mission, 8 patients (3.7%) were diagnosed with lip wound infection and 21 patients (9.6%) with lip dehiscence. After the second mission, only 1 patient (0.4%) returned with a wound infection and 16 (6.4%) were diagnosed with dehiscence.Using binary logistic regression including age, cleft type, postoperative antibiotics, surgeon, and patient education program as covariates, the patient education program stood out as the only variable with a statistically significant impact on the incidence of postoperative wound infections. Even though the incidence of lip dehiscence was reduced by one third when the patient education program was utilized, our regression model singled out the surgeons as the only factor significantly related to this type of complication. Moreover, no benefits of postoperative antibiotic prophylaxis were found. Further analysis of the data also implied that the use of tissue adhesive as a compliment to sutures does not reduce the risk of dehiscence.

Improving patient follow-up in developing regions.

BACKGROUND: Cleft surgery follow-up in developing regions is challenging. This study evaluated rates, costs, and satisfaction of 2 follow-up programs at the Guwahati Comprehensive Cleft Care Centre (GC4) in Assam, India. METHODS: For this study, 10,582 postoperative visits were analyzed from May 2011 to November 2013. A questionnaire was administered to subsets of follow-up patients at both locations. Costs were calculated. RESULTS: Eighty-five percent of patients had follow-up at GC4, and 15% were seen in the patients' local districts. One hundred ninety-five questionnaires were completed (122 at GC4, 73 in local districts). Patients with local follow-up had fewer accompanying family members (mean, 1.95 vs 0.99; P = 0.00), fewer days off work (mean, 1.84 vs 1.15; P = 0.19), less lost income (Indian rupees 367 vs 143, P = 0.00), and lower direct costs (mean Rs, 911 vs 299; P = 0.00). The financial burden of local follow-up was significantly lower (P = 0.003). No significant differences were seen for convenience, likelihood of attending follow-up, or satisfaction. Follow-ups increased after revising programs from a mean of 139 monthly visits (follow-up to surgery ratio of 0.722) to a mean of 363 visits (ratio of 1.57). The center's mean cost for local follow-up was Rs 303 per patient, whereas the estimated costs would have been Rs 1100 for follow-up at the center. CONCLUSIONS: This study demonstrates potential improvements in costs and outcomes by changing the model of care. Despite significant follow-up challenges, much progress can be achieved through process changes and outreach follow-up programs. The results have important applications across the developing world.

Early complications after cleft palate repair: a multivariate statistical analysis of 709 patients.

This study presents a large consecutive institutional experience with primary cleft palate repairs. The purpose of this study was to determine the incidence of early complications after cleft palate surgery in a series of nonsyndromic children treated at the authors' comprehensive cleft center. This retrospective analysis includes 709 consecutive patients with cleft palate treated by 6 different staff surgeons at Guwahati Comprehensive Cleft Care Center between April 2011 and December 2012. Secondary cases were excluded from this study. The patients were initially followed up between 1 week and 1 month after surgery. The overall incidence of early complications was determined, and the effect of the extent of clefting, the type of repair, the age at repair, and the operating surgeon were analyzed. Early complications in this study include dehiscence of the wound, fistula formation, hanging palate, and total or partial flap necrosis. There was a 2.4% rate (17/709) of take-back to the operating room in the immediate postoperative period for control of bleeding, although no blood transfusions were required. The incidence of postoperative fistulas in this series was 3.9% (20/512). There was a statistically significant increase in the incidence of cleft palatal fistula for Veau IV clefts, but there were no significant differences with respect to operating surgeon, patient sex, patient age, and type of palatoplasty. The complication and fistula rate is consistent with other published reports from developed countries and provides evidence for the value of this model for surgical delivery in the developing world.

Scalable, sustainable cost-effective surgical care: a model for safety and quality in the developing world, part I: challenge and commitment.

BACKGROUND: With an estimated backlog of 4,000,000 patients worldwide, cleft lip and cleft palate remain a stark example of the global burden of surgical disease. The need for a new paradigm in global surgery has been increasingly recognized by governments, funding agencies, and professionals to exponentially expand care while emphasizing safety and quality. This three-part article examines the evolution of the Operation Smile Guwahati Comprehensive Cleft Care Center (GCCCC) as an innovative model for sustainable cleft care in the developing world. METHODS: The GCCCC is the result of a unique public-private partnership between government, charity, and private enterprise. In 2009, Operation Smile, the Government of Assam, the National Rural Health Mission, and the Tata Group joined together to work towards the common goal of creating a center of excellence in cleft care for the region. RESULTS: This partnership combined expertise in medical care and training, organizational structure and management, local health care infrastructure, and finance. A state-of-the-art surgical facility was constructed in Guwahati, Assam which includes a modern integrated operating suite with an open layout, advanced surgical equipment, sophisticated anesthesia and monitoring capabilities, central medical gases, and sterilization facilities. CONCLUSION: The combination of established leaders and dreamers from different arenas combined to create a synergy of ambitions, resources, and compassion that became the backbone of success in Guwahati.

Scalable, sustainable cost-effective surgical care: a model for safety and quality in the developing world, part II: program development and quality care.

BACKGROUND: The Guwahati Comprehensive Cleft Care Center (GCCCC) is committed to free medical and surgical care to patients afflicted with facial deformities in Assam, India. A needs-based approach was utilized to assemble numerous teams, processes of care, and systems aimed at providing world-class care to the most needy of patients, and to assist them with breaking through the barriers that prohibit them from obtaining services. METHODS: A team of international professionals from various disciplines served in Guwahati full time to implement and oversee patient care and training of local counterparts. Recruitment of local professionals in all disciplines began early in the scheme of the program and led to gradual expansion of all medical teams. Emphasis was placed on achieving optimal outcome for each patient treated, as opposed to treating the maximum number of patients. RESULTS: The center is open year round to offer full-time services and follow-up care. Along with surgery, GCCCC provides speech therapy, child life counseling, dental care, otolaryngology, orthodontics, and nutrition services for the cleft patients under one roof. Local medical providers participated in a model of graded responsibility commiserate with individualized skill and progress, and gradually assumed all leadership positions and now account for 92% of the workforce. Institutional infrastructure improvements positioned and empowered teams of skilled local providers while implementing systemized perioperative processes. CONCLUSION: This needs-based approach to program development in Guwahati was successful in optimization of quality and safety in all clinical divisions.

Scalable, sustainable cost-effective surgical care: a model for safety and quality in the developing world, part III: impact and sustainability.

BACKGROUND: The Guwahati Comprehensive Cleft Care Center (GCCCC) utilizes a high-volume, subspecialized institution to provide safe, quality, and comprehensive and cost-effective surgical care to a highly vulnerable patient population. METHODS: The GCCCC utilized a diagonal model of surgical care delivery, with vertical inputs of mission-based care transitioning to investments in infrastructure and human capital to create a sustainable, local care delivery system. Over the first 2.5 years of service (May 2011-November 2013), the GCCCC made significant advances in numerous areas. Progress was meticulously documented to evaluate performance and provide transparency to stakeholders including donors, government officials, medical oversight bodies, employees, and patients. RESULTS: During this time period, the GCCCC provided free operations to 7,034 patients, with improved safety, outcomes, and multidisciplinary services while dramatically decreasing costs and increasing investments in the local community. The center has become a regional referral cleft center, and governments of surrounding states have contracted the GCCCC to provide care for their citizens with cleft lip and cleft palate. Additional regional and global impact is anticipated through continued investments into education and training, comprehensive services, and research and outcomes. CONCLUSION: The success of this public private partnership demonstrates the value of this model of surgical care in the developing world, and offers a blueprint for reproduction. The GCCCC experience has been consistent with previous studies demonstrating a positive volume-outcomes relationship, and provides evidence for the value of the specialty hospital model for surgical delivery in the developing world.

Effects of Transition from Remote to In-Person Learning in University Students: A Longitudinal Study.

Previous studies have shown that the transition from the University environment to remote learning impacted student mental health. Our study aimed to investigate the effects of university environment on anxiety and depressive symptoms in health sciences students. Students at the Technical University of Manabí, Ecuador, with 6-10 in-person semesters, who shifted to remote learning and then returned to face-to-face learning were selected. Students responded to the General Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9). In addition, questions regarding social interaction, physical exercise, mood and sleep habits were also asked. This longitudinal study tracked 323 students during the return to in-person classes and term end. The results showed similar rates of anxiety (GAD-7, p = 0.011-p = 0.002) and depression (PHQ-9 p = 0.001-p = 0.032) among students at week 1 and week 15. Previous diagnosis of depression (OR, 0.171; CI 0.050-0.579, p < 0.005) was shown to correlate with depression levels in week 1, with no changes seen at follow-up. Anxiety levels were shown to be associated with a previous diagnosis of the disorder at week 1, but not at follow-up (OR 0.233; CI 0.085-0.643, p < 0.005). The return to in-person learning among university students maintained levels of anxiety and depressive symptoms, underscoring ongoing vulnerabilities to mental health disorders in this group.

Insulin and the kidneys: a contemporary view on the molecular basis.

Insulin is a hormone that is composed of 51 amino acids and structurally organized as a hexamer comprising three heterodimers. Insulin is the central hormone involved in the control of glucose and lipid metabolism, aiding in processes such as body homeostasis and cell growth. Insulin is synthesized as a large preprohormone and has a leader sequence or signal peptide that appears to be responsible for transport to the endoplasmic reticulum membranes. The interaction of insulin with the kidneys is a dynamic and multicenter process, as it acts in multiple sites throughout the nephron. Insulin acts on a range of tissues, from the glomerulus to the renal tubule, by modulating different functions such as glomerular filtration, gluconeogenesis, natriuresis, glucose uptake, regulation of ion transport, and the prevention of apoptosis. On the other hand, there is sufficient evidence showing the insulin receptor's involvement in renal functions and its responsibility for the regulation of glucose homeostasis, which enables us to understand its contribution to the insulin resistance phenomenon and its association with the progression of diabetic kidney disease.

Hippocampal subfield volumes are associated with verbal memory after first-ever ischemic stroke.

INTRODUCTION: Hippocampal subfield volumes are more closely associated with cognitive impairment than whole hippocampal volume in many diseases. Both memory and whole hippocampal volume decline after stroke. Understanding the subfields' temporal evolution could reveal valuable information about post-stroke memory. METHODS: We sampled 120 participants (38 control, 82 stroke), with cognitive testing and 3T-MRI available at 3 months and 3 years, from the Cognition and Neocortical Volume after Stroke (CANVAS) study. Verbal memory was assessed using the Hopkins Verbal Learning Test-Revised. Subfields were delineated using FreeSurfer. We used partial Pearson's correlation to assess the associations between subfield volumes and verbal memory scores, adjusting for years of education, sex, and stroke side. RESULTS: The left cornu ammonis areas 2/3 and hippocampal tail volumes were significantly associated with verbal memory 3-month post-stroke. At 3 years, the associations became stronger and involved more subfields. DISCUSSION: Hippocampal subfield volumes may be a useful biomarker for post-stroke cognitive impairment.

Evaluation of CYP2C19 Gene Polymorphisms in Patients with Acid Peptic Disorders Treated with Esomeprazole.

BACKGROUND: CYP2C19 is a highly polymorphic gene that encodes an enzyme with the same name and whose function is associated with the metabolism of many important drugs, such as proton pump inhibitors (such as esomeprazole, which is used for the treatment of acid peptic disease). Genetic variants in CYP2C19 alter protein function and affect drug metabolism. This study aims to genotypically and phenotypically characterize the genetic variants in the CYP2C19 gene in 12 patients with acid peptic disorders and different therapeutic profiles to proton pump inhibitor (PPI) drugs. The patients were randomly selected from a controlled, randomized and blinded clinical pilot trial of 33 patients. We determined the presence and frequency of single nucleotide polymorphisms (SNPs) within exons 1-5 and 9, the intron-exon junctions, and a fragment in the 3' UTR region of the CYP2C19 gene using Sanger sequencing. Undescribed polymorphisms were analyzed by free online bioinformatics tools to evaluate the potential molecular effects of these genetic variants. RESULTS: We identified nine polymorphisms, six of which had no reported functions. One of these genetic variants, with a functional impact, not yet reported (p.Arg132Trp) was predicted by bioinformatic tools as potentially pathogenic. This finding suggests that p.Arg132Trp could be related to poor metabolizers of drugs metabolized by CYP2C19. CONCLUSION: We identified the genotype spectrum of variants in CYP2C19. The genotype spectrum of variants in CYP2C19 could predict the treatment response and could support to evaluate clinical efficacy in patients treated with esomeprazole.

Patient Satisfaction with Medical Tourism: A Review of 460 International Plastic Surgery Patients in Colombia.

Cosmetic surgery is at the forefront of an exploding medical tourism industry. Patients are able to research options globally through the internet, and increasing numbers are seeking improved service, quality, and value through surgery overseas. Little work has been done to measure the patient experience when traveling for surgery and, to our knowledge, this is the largest study of its kind to examine patient satisfaction with medical tourism. METHODS: We retrospectively reviewed patient satisfaction surveys completed by 460 consecutive international patients receiving cosmetic surgery at a private plastic surgery practice in Cartagena, Colombia, between February 2016 and April 2018. RESULTS: Overall patient satisfaction was excellent, with 98.2% responding that they would refer us to friends and family. Patient satisfaction ratings across all other items was also very high (range: 97.1%-100%) for information provided, the surgeon, the staff, facilities, and payment. CONCLUSIONS: Excellent patient satisfaction is possible with medical tourism if the patient perceives and receives value through effective results, a pleasant experience, and favorable costs. These successes in plastic surgery medical tourism highlight the potential for significant continued growth in this sector as a whole.

[Anesthetic management of neonates undergoing diagnostic and therapeutic cardiac catheterization: a systematic literature review]. / Manejo anestésico de neonatos submetidos a cateterismo cardíaco diagnóstico e terapêutico: uma revisão sistemática da literatura.

BACKGROUND: Several interventional cardiology procedures are required in neonates with congenital heart disease. Interventional cardiology procedures have a higher risk of cardiac arrest compared to other interventions. At present, there is great heterogeneity in the perioperative management of congenital heart disease neonates undergoing diagnostic cardiac catheterization or therapeutic cardiac catheterization. STUDY OBJECTIVES: Primary aim: Provide a systematic review of the most effective and/or safe anesthetic and perioperative management in neonates with congenital heart disease who undergo diagnostic cardiac catheterization or therapeutic cardiac catheterization. Secondary aim: Identify the medications, monitoring parameters and airway management used in the same population. DESIGN: Systematic literature review. SETTING: Catheterization laboratory. METHODS: Literature was searched (December 2017) in electronic databases Medline, EMBASE, ScienceDirect, BIREME-Lilacs-Biblioteca Virtual de la Salud, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects and Health Technology Assessment Database. MAIN RESULTS: From 130 records identified, four studies met inclusion criteria and quality assessment. None of the studies were relevant to the primary objective. Regarding the secondary objectives, one study compared the efficacy and adverse effects of racemic ketamine and its S(+) ketamine enantiomer, one study reported the efficacy of subarachnoid anesthesia for high-risk children undergoing diagnostic cardiac catheterization, one study identified the factors associated to high severity adverse events related to sedation, anesthesia and airway, and one study retrospectively analyzed cardiac catheterization procedures in neonates weighing less than 2.5 kg. CONCLUSION: There are no evidence-based recommendations available for congenital heart disease neonates undergoing cardiac catheterization. More studies are required to evaluate the ideal anesthetic and perioperative management in this population.

Plastic Surgery Medical Tourism in Colombia: A Review of 658 International Patients and 1,796 Cosmetic Surgery Procedures.

BACKGROUND: Cosmetic surgery is at the forefront of a $60 billion medical tourism industry. Patients are now able to research options globally through the internet, and increasing numbers are seeking improved service, quality, and value through surgery overseas. This study examines 658 consecutive patients receiving 1,796 cosmetic surgery procedures at a private plastic surgery practice in Cartagena, Colombia. METHODS: We retrospectively reviewed the medical records of 658 consecutive international patients receiving cosmetic surgery at a private plastic surgery practice in Cartagena, Colombia. RESULTS: Patients traveled to Colombia from 34 different countries spread across 6 continents. Ninety percent of patients came from North America. Patients from the United States represented 38 states and the District of Columbia, and Canadian patients represented 7 provinces. Eighty-three percent of patients were women and 90% were between the age of 20 and 54. The 658 patients in this study had a total of 1,796 cosmetic surgery procedures, involving 5,456 surgical sites. Seventy-two percent of patients received combination procedures with an average of 2.7 procedures per patient. Ninety-nine percent of cases were performed under general anesthesia and 100% were performed in an accredited hospital. CONCLUSIONS: Our data highlight trends defining plastic surgery medical tourism. Our data indicate that traveling for surgery is widely appealing, with women and men from diverse backgrounds traveling to Colombia from all over the world for a variety of procedures.
