Holistic approach to care for patients with endometriosis.

PURPOSE OF REVIEW: Endometriosis is a chronic, often debilitating, disease which is typically managed with surgery and hormonal medications. However, many patients feel they lack agency when managing endometriosis symptoms. The purpose of this review is to discuss the mental and physical management strategies, the long-term health consequences, and the role of a multidisciplinary team in the treatment of endometriosis. RECENT FINDINGS: Evidence is becoming more robust regarding the role of complementary care and physical activity in the management of endometriosis. Health risks such as infertility are well known and newer evidence is evolving regarding perinatal and cardiovascular health risks. There are also trends towards multiple specialist involvement in the care of endometriosis and the benefit of interdisciplinary collaboration. SUMMARY: Endometriosis is a frequently recurrent condition requiring not only meticulous medical and surgical care, but also coordinated longitudinal disease management and impact mitigation. Gynecologists should be aware of the short-term and long-term implications of the disease to empower patients on the management of their overall health.

Assessment of the pathogen genomics landscape highlights disparities and challenges for effective AMR Surveillance and outbreak response in the East African community.

The East African Community (EAC) grapples with many challenges in tackling infectious disease threats and antimicrobial resistance (AMR), underscoring the importance of regional and robust pathogen genomics capacities. However, a significant disparity exists among EAC Partner States in harnessing bacterial pathogen sequencing and data analysis capabilities for effective AMR surveillance and outbreak response. This study assesses the current landscape and challenges associated with pathogen next-generation sequencing (NGS) within EAC, explicitly focusing on World Health Organization (WHO) AMR-priority pathogens. The assessment adopts a comprehensive approach, integrating a questionnaire-based survey amongst National Public Health Laboratories (NPHLs) with an analysis of publicly available metadata on bacterial pathogens isolated in the EAC countries. In addition to the heavy reliance on third-party organizations for bacterial NGS, the findings reveal a significant disparity among EAC member States in leveraging bacterial pathogen sequencing and data analysis. Approximately 97% (n = 4,462) of publicly available high-quality bacterial genome assemblies of samples collected in the EAC were processed and analyzed by external organizations, mainly in Europe and North America. Tanzania led in-country sequencing efforts, followed by Kenya and Uganda. The other EAC countries had no publicly available samples or had all their samples sequenced and analyzed outside the region. Insufficient local NGS sequencing facilities, limited bioinformatics expertise, lack of adequate computing resources, and inadequate data-sharing mechanisms are among the most pressing challenges that hinder the EAC's NPHLs from effectively leveraging pathogen genomics data. These insights emphasized the need to strengthen microbial pathogen sequencing and data analysis capabilities within the EAC to empower these laboratories to conduct pathogen sequencing and data analysis independently. Substantial investments in equipment, technology, and capacity-building initiatives are crucial for supporting regional preparedness against infectious disease outbreaks and mitigating the impact of AMR burden. In addition, collaborative efforts should be developed to narrow the gap, remedy regional imbalances, and harmonize NGS data standards. Supporting regional collaboration, strengthening in-country genomics capabilities, and investing in long-term training programs will ultimately improve pathogen data generation and foster a robust NGS-driven AMR surveillance and outbreak response in the EAC, thereby supporting global health initiatives.

Validation of a Simulation Model for Robotic Myomectomy.

STUDY OBJECTIVE: Several simulation models have been evaluated for gynecologic procedures such as hysterectomy, but there are limited published data for myomectomy. This study aimed to assess the validity of a low-cost robotic myomectomy model for surgical simulation training. DESIGN: Prospective cohort simulation study. SETTING: Surgical simulation laboratory. PARTICIPANTS: Twelve obstetrics and gynecology residents and 4 fellowship-trained minimally invasive gynecologic surgeons were recruited for a 3:1 novice-to-expert ratio. INTERVENTIONS: A robotic myomectomy simulation model was constructed using <$5 worth of materials: a foam cylinder, felt, a stress ball, bandage wrap, and multipurpose sealing wrap. Participants performed a simulation task involving 2 steps: fibroid enucleation and hysterotomy repair. Video-recorded performances were timed and scored by 2 blinded reviewers using the validated Global Evaluative Assessment of Robotic Skills (GEARS) scale (5-25 points) and a modified GEARS scale (5-40 points), which adds 3 novel domains specific to robotic myomectomy. Performance was also scored using predefined task errors. Participants completed a post-task questionnaire assessing the model's realism and utility. MEASUREMENTS AND MAIN RESULTS: Median task completion time was shorter for experts than novices (9.7 vs 24.6 min, p = .001). Experts scored higher than novices on both the GEARS scale (median 23 vs 12, p = .004) and modified GEARS scale (36 vs 20, p = .004). Experts made fewer task errors than novices (median 15.5 vs 37.5, p = .034). For interrater reliability of scoring, the intraclass correlation coefficient was calculated to be 0.91 for the GEARS assessment, 0.93 for the modified GEARS assessment, and 0.60 for task errors. Using the contrasting groups method, the passing mark for the simulation task was set to a minimum modified GEARS score of 28 and a maximum of 28 errors. Most participants agreed that the model was realistic (62.5%) and useful for training (93.8%). CONCLUSION: We have demonstrated evidence supporting the validity of a low-cost robotic myomectomy model. This simulation model and the performance assessments developed in this study provide further educational tools for robotic myomectomy training.

Muscle Mass and Strength Gains Following Resistance Exercise Training in Older Adults 65-75 Years and Older Adults Above 85 Years.

Resistance exercise training (RET) can be applied effectively to increase muscle mass and function in older adults (65-75 years). However, it has been speculated that older adults above 85 years are less responsive to the benefits of RET. This study compares the impact of RET on muscle mass and function in healthy older adults 65-75 years versus older adults above 85 years. We subjected 17 healthy older adults 65-75 years (OLDER 65-75, n = 13/4 [female/male]; 68 ± 2 years; 26.9 ± 2.3 kg/m2) and 12 healthy older adults above 85 years (OLDER 85+, n = 7/5 [female/male]; 87 ± 3 years; 26.0 ± 3.6 kg/m2) to 12 weeks of whole-body RET (three times per week). Prior to, and after 6 and 12 weeks of training, quadriceps and lumbar spine vertebra 3 muscle cross-sectional area (computed tomography scan), whole-body lean mass (dual-energy X-ray absorptiometry scan), strength (one-repetition maximum test), and physical performance (timed up and go and short physical performance battery) were assessed. Twelve weeks of RET resulted in a 10% ± 4% and 11% ± 5% increase in quadriceps cross-sectional area (from 46.5 ± 10.7 to 51.1 ± 12.1 cm2, and from 38.9 ± 6.1 to 43.1 ± 8.0 cm2, respectively; p < .001; η2 = .67); a 2% ± 3% and 2% ± 3% increase in whole-body lean mass (p = .001; η2 = .22); and a 38% ± 20% and 46% ± 14% increase in one-repetition maximum leg extension strength (p < .001; η2 = .77) in the OLDER 65-75 and OLDER 85+ groups, respectively. No differences in the responses to RET were observed between groups (Time × Group, all p > .60; all η2 ≤ .012). Physical performance on the short physical performance battery and timed up and go improved (both p < .01; η2 ≥ .22), with no differences between groups (Time × Group, p > .015; η2 ≤ .07). Prolonged RET increases muscle mass, strength, and physical performance in the aging population, with no differences between 65-75 years and 85+ years older adults.

Development and validation of a simulation model for laparoscopic myomectomy.

BACKGROUND: Simulation is an important adjunct to traditional surgical training, allowing for repetitive practice of new skills without compromising patient safety. Although several simulation models have been described and evaluated for gynecologic procedures, there is a lack of such models for laparoscopic myomectomy. OBJECTIVE: This study aimed to design a low-cost, low-fidelity laparoscopic myomectomy simulation model and to assess the model's validity as a training tool. STUDY DESIGN: The model was constructed using a "cup turner" foam cylinder, felt, a 2-inch stress ball, self-adhesive bandage wrap, multipurpose sealing wrap, red marker, and hook-and-loop fastener. Participants were recruited at a quaternary care academic center and at the Society for Gynecologic Surgeons Annual Scientific Meeting. The simulation task involved the following 2 steps: fibroid enucleation and hysterotomy repair. Validity evidence was collected by comparing expert and novice simulation task performances. Video recordings were scored by 2 blinded reviewers using the Global Operative Assessment of Laparoscopic Skills scale (5-20 points) and a modified Global Operative Assessment of Laparoscopic Skills scale (5-35 points), incorporating 3 novel domains specific to laparoscopic myomectomy. The Mann-Whitney U test was used to compare the task completion times and performance scores. Interrater reliability of scoring was assessed using the interclass correlation coefficient. Validity was also assessed with a post-task survey regarding the model's realism, utility, and educational effect. RESULTS: The total cost to construct each model was under $5. A 3:1 ratio was used to recruit 15 novices and 5 experts. The median time to task completion was shorter for experts than for novices (11.8 vs 20.1 minutes; P=.004). The experts scored higher than the novices on both the Global Operative Assessment of Laparoscopic Skills scale (median 19 [range 13-20] vs 10 [6-17.5]; P=.007) and the modified Global Operative Assessment of Laparoscopic Skills scale (31.5 [21.5-33.5] vs 18.5 [13.5-32]; P=.009). The interclass correlation coefficient was 0.95 for the Global Operative Assessment of Laparoscopic Skills scores and 0.96 for the modified Global Operative Assessment of Laparoscopic Skills scores. Most of the participants agreed that the model closely approximated the feel of fibroid enucleation (70% [14/20]) and suturing the uterus (80% [16/20]). All the participants agreed that the model was useful for learning or teaching laparoscopic myomectomy. CONCLUSION: This study demonstrates evidence supporting the validity of a novel, low-cost laparoscopic myomectomy model and a novel assessment scale for laparoscopic myomectomy training. This simulation model provides a targeted training tool that allows learners to focus on the key aspects of laparoscopic myomectomy and may improve readiness for the operating room.

Rates of Complications and Reoperation after Myomectomy-the Impact of Surgical Approach: A Statewide Population-based Cohort Study from 2005-2018.

STUDY OBJECTIVE: To assess rates of and factors associated with complications and reoperation after myomectomy. DESIGN: Population-based cohort study. SETTING: All non-Veterans Affairs facilities in the state of California from January 1, 2005, to December 31, 2018. PARTICIPANTS: Women undergoing abdominal or laparoscopic myomectomy for myoma disease were identified from the Office of Statewide Health Planning and Development datasets using appropriate International Classification of Diseases, Ninth and Tenth Revision and Current Procedural Terminology codes. INTERVENTIONS: Demographics, surgery facility type, facility surgical volume, and surgical approach were identified. Primary outcomes included complications occurring within 60 days of surgery and reoperations for myomas. Patients were followed up for over an average of 7.3 years. Univariate and multivariable associations were explored between the above factors and rates of complications and reoperation. All odds ratios (ORs) are adjusted ORs. MEASUREMENTS AND MAIN RESULTS: Of the 66 012 patients undergoing myomectomy, 5265 had at least one complication (8.0%). Advanced age, black, Asian race, MediCal and Medicare payor status, academic facility, and medical comorbidities were associated with increased odds of a complication. Minimally invasive myomectomy (MIM) was associated with decreased complications compared with abdominal myomectomy (AM) (OR, 0.29; 95% confidence interval [CI], 0.25-0.33; p <.001). Overall, 17 377 patients (26.3%) underwent reoperation. Medicare and MediCal payor status and medical comorbidities were associated with increased odds of a repeat surgery. Reoperation rates were higher in the MIM group over the entire study period (OR, 2.33; 95% CI, 1.95-2.79; p <.001). However, the odds of reoperation after MIM decreased each year (OR, 0.93; 95% CI 0.92-0.95; p <.001), with the odds of reoperation after AM surpassing MIM in 2015. CONCLUSION: This study identifies outcome disparities in the surgical management of myomas and describes important differences in the rates of complications and reoperations, which can be used to counsel patients on surgical approach. These findings suggest that MIM can be considered a lasting and safe approach in properly selected patients.

The Impact of Race and Ethnicity on Use of Minimally Invasive Surgery for Myomas.

STUDY OBJECTIVE: To determine whether minimally invasive surgery (MIS) for uterine myomas is used differentially based on race and ethnicity. DESIGN: Retrospective cohort study. SETTING: Quaternary care academic hospital in the United States. PATIENTS: Patients undergoing hysterectomy or myomectomy for uterine myomas between March 15, 2015, and March 14, 2020 (N = 1311). Cases involving correction of pelvic organ prolapse, malignancy, peripartum hysterectomy, or combined procedures with nongynecologic specialties were excluded. Racial/ethnic composition of the study population was 40.0% non-Hispanic white (white), 27.9% non-Hispanic black (black), 14.0% Hispanic, 13.7% non-Hispanic Asian (Asian), and 4.3% non-Hispanic American Indian/Alaska Native/Pacific Islander/Other. INTERVENTIONS: Hysterectomy, myomectomy. MEASUREMENTS AND MAIN RESULTS: Of the 1311 cases, 35.9% were minimally invasive hysterectomy, 16.4% abdominal hysterectomy, 35.6% minimally invasive myomectomy, and 12.1% abdominal myomectomy. MIS rates were 94.7% among fellowship-trained minimally invasive gynecologic surgery subspecialists, 44.2% among obstetrics and gynecology specialists, and 46.8% among gynecologic oncologists. There were disparities in surgeon type based on race/ethnicity, with 59.8% of white patients having undergone surgery with a minimally invasive gynecologic surgery subspecialist vs 44.0% of black patients and 45.7% of Hispanic patients. Black and Hispanic patients were less likely to undergo MIS overall vs white patients (adjusted odds ratio [aOR] 0.33, 95% confidence interval [CI] 0.22-0.48 and aOR 0.44, 95% CI 0.28-0.72, respectively). Black and Hispanic patients undergoing hysterectomy were less likely than white patients to undergo MIS (aOR 0.33, 95% CI 0.21-0.51 and aOR 0.35, 95% CI 0.20-0.60, respectively). There were no significant differences in rates of MIS based on race/ethnicity for myomectomies nor differences in major or minor complications by race/ethnicity overall. CONCLUSION: At a quaternary care institution, black and Hispanic patients were significantly less likely than white patients to undergo MIS for uterine myomas, particularly for hysterectomy.

Sensitization of depressive-like behavior is attenuated by disruption of prostaglandin synthesis days following brief early attachment-figure isolation.

Childhood psychological trauma appears to sensitize stress-related neuroinflammatory systems to increase later vulnerability for depression and other stress-related mental disorders. Isolation of guinea pig pups from the maternal attachment figure for 3 h in threatening surroundings leads to a sensitization of inflammatory-mediated, depressive-like behavior and fever during later isolations. A previous study found the non-selective COX inhibitor naproxen administered before the initial isolation moderated depressive-like behavior and its sensitization. Here, we examined effects of naproxen given following early isolation. Male and female guinea pig pups surgically implanted with telemetry devices to measure core temperature were isolated for 3 h on 2 consecutive days near weaning (first isolation Day 20-24). Several days later, they began 4 consecutive days of injection with either saline vehicle or 10 or 20 mg/kg naproxen prior to a third isolation in early adolescence, that is, 10 days after their first isolation. Across the first two isolations, depressive-like behavior and fever sensitized. Both doses of naproxen attenuated depressive-like behavior during the third isolation. Fever was unaffected. Results suggest prostaglandin mediation of sensitization of depressive-like behavioral, but not febrile, responses to subsequent isolation. Findings also support further study of anti-inflammatory treatments to mitigate lasting consequences of early-attachment disruption.

[Quality of life, level of physical activity and functional tests in actively working adults and older people]. / Calidad de vida, nivel de actividad física y pruebas funcionales en personas adultas y mayores laboralmente activas.

BACKGROUND: The population of actively working older people is growing rapidly. The relationship between quality of life, levels of physical activity and functionality in this population is not entirely clear. AIM: To determine the association between quality of life, levels of physical activity and functional tests in actively working adults and older people. MATERIAL AND METHODS: Cross sectional assessment of 138 adults aged 40 to 50 years (53% women) and 119 older people aged 60 to 75 years (53% women) who were actively working in two public services. Quality of life was measured with the SF-36 questionnaire and usual physical activity was assessed with the International Physical Activity Questionnaire (IPAQ-short). Handgrip strength, the timed up and go (TUG) and chair stand test (CST) were used as functional tests. RESULTS: Compared to older people, adults had better physical functional tests (P < 0.01). Older people had better scores in the mental health component (MHC) of quality of life (p < 0.05). In adults, the physical health component of quality of life (CSF) had a positive association with physical activity (Spearman Rho (rs)= 0.270; p = 0.01), grip strength (rs = 0.330; p < 0.01) and the TUG (rs = -0.229; p < 0.01). In older patients, CSM and CST were positively correlated (rs = 0.201; P = 0.029). In both groups, a correlation was observed between CSM, grip strength (adults rs = 0.283; p < 0.01; older people rs = 0.211; P = 0.02) and with TUG (adults rs = -0.197; P = 0.021; older people rs = - 0.212; p = 0.02). CONCLUSIONS: There is a positive correlation between quality of life and level of physical activity in working adults, which is not observed in older people. Adequate performance in physical functional tests is positively correlated with better quality of life (CSF and CSM) in adults and only with the mental health component in older people.

Postoperative Urinary Retention after Benign Gynecologic Surgery with a Liberal versus Strict Voiding Protocol.

STUDY OBJECTIVE: Surgeons employ various methods for evaluating what is considered a common occurrence after gynecologic operations, postoperative urinary retention (POUR). Few have reported the incidence of POUR with a liberal voiding protocol (no requirement to void before discharge). The primary objective of this study was to evaluate the risk of POUR after benign gynecologic surgery, comparing a liberal voiding protocol with more strict voiding protocols. Secondary outcomes included length of hospital stay (LOS) and urinary tract infection (UTI). DESIGN: Retrospective cohort study. SETTING: Quaternary-care academic hospital in the United States. PATIENTS: Patients undergoing hysterectomy or myomectomy at Cedars-Sinai Medical Center from August 2017 through July 2018 (n = 652). Cases involving incontinence operations, correction of pelvic organ prolapse, malignancy, or peripartum hysterectomy were excluded. INTERVENTIONS: Hysterectomy, myomectomy. MEASUREMENTS AND MAIN RESULTS: POUR, defined as the need for recatheterization within 24 hours of catheter removal, along with UTI and LOS were compared between liberal and strict voiding protocols. A subgroup analysis was performed for those undergoing minimally invasive surgery (MIS). A total of 303 (46.5%) women underwent surgery with a liberal postoperative voiding protocol and 349 (53.5%) women with a strict voiding protocol. Overall, the incidence of POUR was low at 3.8% and not different between the groups (2.6% liberal vs. 4.9% strict, p = .14). UTIs also occurred infrequently (2.8% overall, 2.6% liberal vs. 2.9% strict, p = .86). Similar results were seen specifically among those who underwent MIS: POUR (3.7% overall, 2.8% liberal vs. 5.3% strict, p = .17) and UTI (3.3% overall, 2.4% liberal vs. 4.7% strict, p = .28). The median LOS (interquartile range) was much shorter for MIS patients with a liberal voiding protocol (median 15 hours overall [interquartile range 15 hours], 9 [4] hours liberal vs. 36 [34] hours strict, p <.01). Among those discharged the same day (72.6% of the MIS cases), patients with a liberal voiding protocol had a significantly shorter LOS than those with strict (mean [standard deviation] 9.4 [2.5] hours vs. 10.6 [35] hours, p <.01). Postoperative complications occurred less frequently in those with MIS procedures (11.8% in MIS vs. 20.2% in laparotomies, p <.01) and those with liberal voiding protocols (11.2% liberal vs. 16.9% strict p = .04). CONCLUSION: Overall, POUR occurs infrequently after major benign gynecologic surgery and does not differ between those with liberal and strict voiding protocols. Our data suggest that same-day discharge after MIS hysterectomy and myomectomy without a requirement to void does not increase the risk of POUR and shortens LOS. Eliminating voiding protocols after these procedures may facilitate greater efficiency in the postanesthesia recovery unit and may contribute to enhanced recovery after surgery protocols.

Presence of mother prompts dissociation of sickness behavior, fever, and hypothalamic gene expression in lipopolysaccharide-injected guinea pig pups.

During infection, sickness behaviors, such as a hunched stance with piloerection, can facilitate host resistance by supporting the generation and maintenance of fever. Fever, in turn, is mediated by hypothalamic neuroimmune signaling. Sickness behaviors, however, can also be influenced by social stimuli. In this study, guinea pig pups were injected with lipopolysaccharide to simulate a bacterial infection and then exposed to a novel, threatening environment while either with their mother or alone. We found that the presence of the mother suppressed sickness behavior, but enhanced fever, and had no measureable effect on gene expression of hypothalamic mediators of fever. This 3-way dissociation induced by the mother's presence is interpreted in terms of the differential adaptive consequences of behavioral and febrile responses for pups in this situation. The results contribute to a growing literature linking immunological and social processes.

The impact of parallel regulatory-health technology assessment scientific advice on clinical development. Assessing the uptake of regulatory and health technology assessment recommendations.

AIMS: The parallel regulatory-health technology assessment scientific advice (PSA) procedure allows manufacturers to receive simultaneous feedback from both EU regulators and health technology assessment (HTA) bodies on development plans for new medicines. The primary objective of the present study is to investigate whether PSA is integrated in the clinical development programmes for which advice was sought. METHODS: Contents of PSA provided by regulators and HTA bodies for each procedure between 2010 and 2015 were analysed. The development of all clinical studies for which PSA had been sought was tracked using three different databases. The rate of uptake of the advice provided by regulators and HTA bodies was assessed on two key variables: comparator/s and primary endpoint. RESULTS: In terms of uptake of comparator recommendations at the time of PSA in the actual development, our analysis showed that manufacturers implemented comparators to address both the needs of regulators and of at least one HTA body in 12 of 21 studies. For primary endpoints, in all included studies manufacturers addressed both the needs of the regulators and at least one HTA body. CONCLUSIONS: One of the key findings of this analysis is that manufacturers tend to implement changes to the development programme based on both regulatory and HTA advice with regards to the choice of primary endpoint and comparator. It also confirms the challenging choice of the study comparator, for which manufacturers seem to be more inclined to satisfy the regulatory advice. Continuous research efforts in this area are of paramount importance from a public health perspective.

Vigilance for Salmonella in Feedstuffs Available in Costa Rica: Prevalence, Serotyping and Tetracycline Resistance of Isolates Obtained from 2009 to 2014.

Relevant epidemiological information is provided in this report for Salmonella based on data obtained from a Costa Rican surveillance program for animal feeds. In addition to prevalence, a description in terms of serotypes and tetracycline (TET) resistance of the isolates is included. A total of 1725 feed and feed ingredients samples were analyzed during 2009 and 2014, from which 110 Salmonella strains were recovered (76 from poultry, 23 from meat and bone meal [MBM], 3 from pet foods, and 8 from other feed). Retrieved isolates were serotyped and tested for minimum inhibitory concentration (MIC) against TET. Salmonella strains were found mainly from poultry feed (different growth stages, n = 76/110; 69.1%) and MBM (n = 23/109; 21.1%). The rest of the isolates were recovered from feather meal, pet food, fish meal (n = 3/110; 2.3% each) and swine feed (n = 1/110; 0.9%). From the different serotypes recovered (n = 21), the most common were Salmonella Give (n = 18; 13.8%) and Salmonella Rissen (n = 6; 4.6%) for MBM and Salmonella Havana (n = 14; 10.8%), Salmonella Rissen, Salmonella Soerenga, and Salmonella Schwarzengrund (n = 8; 6.2% each) in poultry feed. Recovered strains were regarded to be sensitive or have an intermediate resistance to TET as evidenced by their MIC50 and MIC90 concentrations of 4 and 8 µg/mL for MBM and poultry feed, respectively. Compound feed and MBM samples exhibited strains characterized by 86.8 and 88.9% of the isolates classified (according to CLSI, 2015 ) as sensitive, 7.7 and 3.7% as intermediate, and 5.5% (with >256 µg/mL as the highest concentration) and 7.4% (with 64 µg/mL as the highest concentration) as resistant to TET, respectively. Salmonella serovars Anatum and Havana exhibited the highest resistance profile >256 and 128 µg/mL, respectively. Hence, MBM and poultry feed seem to be a target of interest if Salmonella incidence is to be controlled. Serotypes recovered have in the past demonstrated pathogenic capability; therefore, hereafter a stricter surveillance program may be in order.

Hazard prioritization and risk characterization of antibiotics in an irrigated Costa Rican region used for intensive crop, livestock and aquaculture farming.

Antibiotics alter the homeostasis of microbial communities and select for antibiotic-resistant bacteria in the wild. Thus, the accumulation of unnaturally high concentration of these substances in the environment due to their use in human activities can be regarded as a neglected form of pollution, especially in countries with agricultural-based economies. Qualitative and quantitative information on antibiotic usage in Costa Rica is scarce, hence the design and enforcement of prevention strategies and corrective measures is difficult. To address this issue, and aiming in the long run to contribute with a more rational use of pharmaceuticals in the tropics, we characterized the hazard associated with the antibiotics used during 2008 in agriculture, aquaculture, pig farming, veterinary medicine and human medicine in the major irrigation district of Costa Rica. Hazard indicators were calculated based on antibiotic use and a weighted algorithm that also considered antibiotic fate, toxicity, and resistance. Moreover, hazard quotients were computed using maximum environmental concentrations reported for Costa Rican surface waters and predicted no effect concentrations for aquatic organisms. The number of antibiotics used in the ATID during the study were n = 38 from 15 families. Antibiotic consumption was estimated at 1169-109908 g ha(-1) year(-1) and, distinctively, almost half of this figure was traced back to phenicols. Tetracyclines, with a particular contribution of oxytetracycline, were the most widely used antibiotics in agriculture and veterinary medicine. Oxytetracycline, florfenicol, chlortetracycline, sulfamethoxazole, erythromycin, ciprofloxacin, enrofloxacin, sulfamethazine, trimethoprim and tylosin, in that order showed the highest hazard indicators. Moreover, hazard quotients greater than 1 were calculated for oxacillin, doxycycline, oxytetracycline, sulfamethazine, and ciprofloxacin. Studies dealing with the ecotoxicology of tetracyclines, sulfonamides and quinolones, as well as surveys of phenicol resistance among environmental bacteria, should be prioritized in Costa Rica.

Molecular characterization of antibiotic resistant Salmonella enterica across the poultry production chain in Costa Rica: A cross-sectional study.

Antibiotic resistant Salmonella enterica are on the increase, worldwide. Given the scarcity of data, this study aimed to investigate its occurrence, virulence, and antibiotic resistance in Costa Rica's food chain. In total, 65 chicken meat- and 171 chicken caecal samples were collected and examined for Salmonella. High frequencies of Salmonella were found in chicken meat (58.5 %, n/N = 38/65) and poultry farms (38.0 %, n/N = 65/171). The majority of Salmonella from chicken meat (89.5 %, n/N = 34/38) and caecum samples (93.6 %, n/N = 59/63) exhibited multidrug resistance (MDR). Serovar Infantis was the most prevalent (94 %, n/N = 67/71), followed by serovars Anatum and Kentucky (3 %, n/N = 2/71). A pESI-like plasmid (92 %, n/N = 65/71) containing virulence and resistance markers was found in S. Infantis. Given the high prevalence of MDR Salmonella, this study emphasizes the need to enhance surveillance systems for foodborne pathogens and antimicrobial resistance in Costa Rica's food production chain.

Improvements in performance based measures of functional capacity and cognition after computerized functional skills training in older people with mild cognitive impairment and healthy comparators.

With no pharmacological treatments for Mild Cognitive impairment (MCI), computerized training strategies have been attempted. A computerized skills training intervention, FUNSAT, previously produced training-related gains in cognition in MCI and in comparators with normal cognition (NC). A new remotely delivered version of FUNSAT was administered to a new sample of participants with NC and MCI. Outcomes measures included cognition (BAC) and functional capacity (VRFCAT) to examine training transfer. Participants with MCI (n = 92) and NC (n = 72) trained for up to 12 weeks on FUNSAT. Half the MCI participants started with 3 weeks of computerized cognitive training (CCT). Baseline, post-training, and 30-day follow-up scores on cognition and functional capacity were compared. Participants improved on both cognition (d = 0.80) and functional capacity (d = 0.64), with no differences in training gains across MCI and NC, although treatment with CCT in MCI was associated with similar gains with fewer FUNSAT training sessions. This is the first treatment study in MCI to demonstrate transfer to untrained measures of functional capacity. NC improved in cognition and functional capacity with skills training alone. These findings have implications for other conditions, such as schizophrenia, where functional capacity is a treatment target.

Effectiveness and safety of oral anticoagulants for non-valvular atrial fibrillation: a population-based cohort study in primary healthcare in Catalonia.

Objectives: Our objective was to analyse effectiveness and safety of oral anticoagulants (OAC) for stroke prevention in non-valvular atrial fibrillation. Material and methods: Population-based cohort study including adults initiating oral anticoagulants, either direct oral anticoagulants (DOAC) or vitamin K antagonists (VKA), during 2011-2020. Data source: SIDIAP, capturing information from the electronic health records of Primary Health Care in Catalonia, Spain. Study outcomes: stroke, cerebral and gastrointestinal (GI) haemorrhage, assessed by patients' subgroups according to different clinical characteristics. Results: We included 90,773 patients. Male sex, older than 75, previous event, peripheral artery disease, deep vein thrombosis, or receiving antiplatelets, antidiabetics or proton pump inhibitors (PPI) was associated with higher stroke risk. For DOAC-treated, treatment switch increased stroke risk, while being adherent had a protective effect. Men, antidiabetic treatment or a previous event increased the risk of cerebral bleeding. Receiving direct oral anticoagulants had a protective effect in comparison to vitamin K antagonists. For DOAC-treated, treatment switch increased, and adherence decreased the bleeding risk. Men, people with chronic kidney disease or a previous event posed an increased risk of gastrointestinal bleeding, whereas receiving PPI had a protective effect. For DOAC-treated, switch was associated with a higher bleeding risk. Conclusion: Being men, a previous event and DOAC-switch posed a higher risk for all study outcomes. direct oral anticoagulants had a protective effect against cerebral bleeding in comparison to vitamin K antagonists. Adherence to direct oral anticoagulants resulted in lower risk of stroke and cerebral bleeding. We found no differences in the risk of stroke and gastrointestinal bleeding when we compared direct oral anticoagulants vs. vitamin K antagonists.

Monitoring adherence and abstinence of cannabis use disorder patients: Profile identification and relationship with long-term treatment outcomes.

BACKGROUND: Patients with cannabis use disorder (CUD) show heterogeneous sociodemographic and consumption patterns. Although previous studies, focused on identifying subgroups of CUD patients using input variables, have yielded useful results for planning individualized treatments, no published research has analyzed the profiles of CUD patients according to their therapeutic progress. This study therefore aims to identify subgroups of patients using adherence and abstinence indicators and to explore whether these profiles are associated with sociodemographic characteristics, consumption variables, and long-term therapeutic outcomes. METHODS: This was a retrospective observational study with a multisite sample of 2055 CUD outpatients who were beginning treatment. The study monitored patient data at two-year follow-up. We conducted latent profiles analysis on the appointment attendance ratio and percentage of negative cannabis tests. RESULTS: A three profile solution emerged: i) moderate abstinence/moderate adherence (n = 997); ii) high abstinence/moderate adherence (n = 613); and iii) high abstinence/high adherence (n = 445). The study found the most marked differences at the beginning of treatment for education level (chi2 (8) = 121.70, p < .001), source of referral (chi2 (12) = 203.55, p < .001), and frequency of cannabis use (chi2 (10) = 232.39, p < .001). Eighty percent of patients from the "high abstinence/high adherence" group were relapse-free at two year follow-up. This percentage decreased to 24.3 % in the "moderate abstinence/moderate adherence" group. CONCLUSIONS: Research has shown adherence and abstinence indicators to be useful for identifying subgroups of patients with different prognoses regarding long-term success. Recognizing the sociodemographic and consumption variables associated with these profiles at the beginning of treatment could help to inform the design of more individualized interventions.

Characterization of muscle mass, strength and mobility of critically ill patients with SARS-CoV-2 pneumonia: Distribution by sex, age, days on mechanical ventilation, and muscle weakness.

Objective: Quantify and categorize by sex, age, and time spent on mechanical ventilation (MV), the decline in skeletal muscle mass, strength and mobility in critically ill patients infected with SARS-CoV-2 and requiring mechanical ventilation while at intensive care unit (ICU). Design: Prospective observational study including participants recruited between June 2020 and February 2021 at Hospital Clínico Herminda Martin (HCHM), Chillán, Chile. The thickness of the quadriceps muscle was evaluated by ultrasonography (US) at intensive care unit admission and awakening. Muscle strength and mobility were assessed, respectively, through the Medical Research Council Sum Score (MRC-SS) and the Functional Status Score for the Intensive Care Unit Scale (FSS-ICU) both at awakening and at ICU discharge. Results were categorized by sex (female or male), age (<60 years old or ≥60 years old) and time spent on MV (≤10 days or >10 days). Setting: Intensive care unit in a public hospital. Participants: 132 participants aged 18 years old or above (women n = 49, 60 ± 13 years; men n = 85, 59 ± 12 years) admitted to intensive care unit with a confirmed diagnosis of severe SARS-CoV-2 and requiring MV for more than 48 h were included in the study. Patients with previous physical and or cognitive disorders were excluded. Interventions: Not applicable. Results: Muscle thickness have significantly decreased during intensive care unit stay, vastus intermedius (-11%; p = 0.025), rectus femoris (-20%; p < 0.001) and total quadriceps (-16%; p < 0.001). Muscle strength and mobility were improved at intensive care unit discharge when compared with measurements at awakening in intensive care unit (time effect, p < 0.001). Patients ≥60 years old or on MV for >10 days presented greater muscle loss, alongside with lower muscle strength and mobility. Conclusion: Critically ill patients infected with SARS-CoV-2 and requiring MV presented decreased muscle mass, strength, and mobility during their intensive care unit stay. Factors associated with muscle mass, such as age >60 years and >10 days of MV, exacerbated the critical condition and impaired recovery.

High-intensity interval training reduces the induction of neutrophil extracellular traps in older men using live-neutrophil imaging as biosensor.

Neutrophil extracellular trap formation (NETosis) is a mechanism used by neutrophils to capture pathogens with their own DNA. However, the exacerbation of this immune response is related to serious inflammatory diseases. Aging is known to lead to an excessive increase in NETosis associated with various diseases. Under this scenario, the search for strategies that regulate the release of NETosis in older people becomes relevant. High-intensity interval training (HIIT) involves repeated bouts of relatively intense exercise with alternating short recovery periods. This training has shown beneficial effects on health parameters during aging and disease. However, little is known about the potential role of HIIT in the regulation of NETosis in healthy older people. The aim of this study was to evaluate the induction of NETosis by serum from healthy young and older men, before and after 12 weeks of HIIT using healthy neutrophils as a biosensor. HIIT was performed 3 times per week for 12 weeks in young (YOUNG; 21 ± 1 years, BMI 26.01 ± 2.64 kg⋅m-2, n = 10) and older men (OLDER; 66 ± 5 years, BMI 27.43 ± 3.11 kg⋅m-2, n = 10). Serum samples were taken before and after the HIIT program and NETosis was measured with live cell imaging in donated neutrophils cultured with serum from the participants for 30 h. Our results showed that serum from older men at baseline induced greater baseline NETosis than younger men (p < 0.05; effect size, ≥0.8), and 12 weeks of HIIT significantly reduced (Interaction Effect, p < 0.05; effect size, 0.134) the induction of NETosis in older men. In conclusion, HIIT is a feasible non-invasive training strategy modulating NETosis induction. Additionally, the use of neutrophils as a biosensor is an effective method for the quantification of NETosis induction in real time.
