- Abstract
(1) Background: The effects of lockdown repetition on work-related stress, expressed through Effort-Reward Imbalance (ERI), during the COVID-19 pandemic are poorly documented. We investigated the effect of repetitive lockdowns on the ERI in French workers, its difference across occupations, and the change in its influencing factors across time. (2) Methods: Participants were included in a prospective cross-sectional observational study from 30 March 2020 to 28 May 2021. The primary outcome was the ERI score (visual analog scale). The ERI score of the population was examined via Generalized Estimating Equations. For each period, the factors influencing ERI were studied by multivariate linear regression. (3) Results: In 8121 participants, the ERI score decreased in the first 2 lockdowns (53.2 ± 0.3, p < 0.001; 50.5 ± 0.7, p < 0.001) and after lockdown 2 (54.8 ± 0.8, p = 0.004) compared with the pre-pandemic period (59 ± 0.4). ERI was higher in medical than in paramedical professionals in the pre-pandemic and the first 2 lockdowns. Higher workloads were associated with better ERI scores. (4) Conclusions: In a large French sample, Effort-Reward Imbalance worsened during the COVID-19 pandemic until the end of the 2nd lockdown. Paramedical professionals experienced a higher burden of stress compared with medical professionals.

- Abstract
Objective: The aim of this study was to assess incidence, causes and consequences of equipment failures in a high volume, advanced endoscopic surgery department., Methods: This is a prospectical observational single centre study between April and July of 2019 in the Gynecological surgery department of the Estaing University Hospital of Clermont-Ferrand, France. During the study period, 171 laparoscopies were observed. Data were collected real time by three supernumerary observers., Results: In total, 66 (38.6%) laparoscopies were complicated by equipment failures. The bipolar cable and forceps accounted for 31% of the total amount of malfunctions in laparoscopy. Causes of malfunctions were in 45% due to the instrument per se and in 43% due to the incorrect combination of elements. Less commonly, the equipment was not available or a mismatched was reported. The total length of the surgery increased by 1.35% due to the malfunctions. Human error was identified in 50% of cases. No morbility, neither mortality was reported in this series; however we observed 34 malfunctions that could have led to serious consequences for the patients and 3 incidents induced a real consequence on the operation workflow., Conclusions: Equipment failure is a common event in endoscopy. On the opposite, time wasted for the malfunctions is low in laparoscopy, as it only accounts for 1.35% of the overall surgical time. Human decisions contributed to malfunctions in almost half of cases. This alarming finding may advise for intensification in training on instruments of the whole surgical team., (Copyright © 2020.

- Abstract
The cavus foot deformity is an often less understood deformity within the spectrum of foot and ankle conditions. The hallmark concern is the possibility of an underlying neurologic or neuromuscular disorder. Although a proportion of these deformities are idiopathic, a significant majority do correlate with an underlying disorder. The appropriate evaluation of this deformity, in coordination within the multidisciplinary scope of health care, allows for a timely diagnosis and understanding of the patient's condition. We provide an abbreviated survey of possible underlying etiologies for the patient with the cavus foot deformity as a reference to the foot and ankle surgeon., Competing Interests: Disclosure Drs H.J.

- Abstract
Bony alignment is the primary goal in foot and ankle reconstruction of the cavovarus foot. This condition presents as a malalignment causing a medial overload of the ankle articular surface and lateral overload of the hindfoot, midfoot, and forefoot. A painful gait associated with articular degeneration of the numerous joints can lead to a chronic and rigid arthrosis of joints, warranting arthrodesis of the affected joints accordingly., Competing Interests: Disclosure The author has nothing to disclose., (Copyright © 2021 Elsevier Inc.

- Abstract
Travelers' diarrhea (TD) is the most prevalent illness encountered by deployed military personnel and has a major impact on military operations, from reduced job performance to lost duty days. Frequently, the etiology of TD is unknown and, with underreporting of cases, it is difficult to accurately assess its impact. An increasing number of ailments include an altered or aberrant gut microbiome. To better understand the relationships between long-term deployments and TD, we studied military personnel during two nine-month deployment cycles in 2015-2016 to Honduras. To collect data on the prevalence of diarrhea and impact on duty, a total of 1173 personnel completed questionnaires at the end of their deployment. 56.7% reported reduced performance and 21.1% reported lost duty days. We conducted a passive surveillance study of all cases of diarrhea reporting to the medical unit with 152 total cases and a similar pattern of etiology. Enteroaggregative E. coli (EAEC, 52/152), enterotoxigenic E. coli (ETEC, 50/152), and enteropathogenic E. coli (EPEC, 35/152) were the most prevalent pathogens detected. An active longitudinal surveillance of 67 subjects also identified diarrheagenic E. coli as the primary etiology (7/16 EPEC, 7/16 EAEC, and 6/16 ETEC). Eleven subjects were recruited into a nested longitudinal substudy to examine gut microbiome changes associated with deployment. A 16S rRNA amplicon survey of fecal samples showed differentially abundant baseline taxa for subjects who contracted TD versus those who did not, as well as detection of taxa positively associated with self-reported gastrointestinal distress. Disrupted microbiota was also qualitatively observable for weeks preceding and following the incidents of TD. These findings illustrate the complex etiology of diarrhea amongst military personnel in deployed settings and its impacts on job performance. Potential factors of resistance or susceptibility can provide a foundation for future clinical trials to evaluate prevention and treatment strategies., Competing Interests: One of the coauthors, Jamie Fraser, is affiliated with the non-profit Henry M. Jackson Foundation. The Henry M. Jackson Foundation only provided Fraser with a salary, and did not have any role in our study design, execution, or manuscript preparation.

- Abstract
Aim: To evaluate the adequacy and effect of preventive antiepileptic treatment in adult patients with the first epileptic seizure in adverse outcomes at 30 days after discharge from the hospital emergency department (HED)., Patients and Methods: ACESUR was an observational registry of multipurpose, prospective and multicentric cohorts with a systematic sampling. Phone follow-up was done at 30 days. Clinical variables were collected in the index visit and the follow-up result. The main variable was «adequate preventive treatment according to indications» and the result of «some adverse outcome» (recurrence of epileptic seizure, revisits to HED, hospitalization or death) 30 days after discharge from HED. A logistic regression model was used to isolate the effect of adequate preventive treatment., Results: 151 (22.7%) patients with a mean age of 55 years old were included with first epileptic seizure discharged from 18 HED with follow-up data. Preventive treatment was considered adequate in 128 (84.8%) patients. 41 (27.2%) patients presented some adverse outcome 30 days after discharge. After the logistic regression, the appropriate preventive treatment to the discharge of the HED exerts a protective effect on the variable «some adverse outcome to 30 days»., Conclusions: In the ACESUR registry, preventive treatment was adequate for most patients and its effect was independent protective at 30 days. Therefore, adequate preventive treatment could improve the short-term results of adult patients discharged with the first epileptic seizure of the HED.

- Abstract
Background: Violence against women is a global public health problem with negative effects on physical, mental, and reproductive health. The World Health Organization (WHO) has identified intimate partner violence (IPV) and sexual violence (SV) as major targets for prevention and amelioration and recently developed clinical and policy guidelines to assist healthcare providers. This project was undertaken to determine the 2013 baseline national policies and clinical guidelines on IPV and SV within the Latin American and Caribbean (LAC) region to identify strengths and gaps requiring action., Methods: Each Pan American Health Organization/World Health Organization Regional Office for the Americas (PAHO/WHO) country focal point was contacted to request their current national policy and clinical guidelines (protocol) on IPV/SV. We augmented this by searching the internet and the United Nations Women website. Each country's policy and clinical guideline (where available) was reviewed and entered into a scoring matrix based on WHO Clinical and Policy Guidelines. A total score for each heading and subheading was developed by adding positive responses to identify LAC regional strengths and gaps., Results: We obtained 15 national policies and 12 national clinical guidelines (protocols) from a total of 18 countries ("response" rate 66.7%). National policies were comprehensive in terms of physical, emotional, and sexual violence and recommended good intersectoral collaboration. The greatest gap was in the training of health-care providers. National Guidelines for women-centered care for IPV/SV survivors were strong in the vital areas of privacy, confidentiality, danger assessment, safety planning, and supportive reactions to disclosure. The largest gaps noted were again in training healthcare professionals and strengthening monitoring and evaluation of services., Conclusions: Baseline measurement of policy and clinical guidelines for IPV/SV in LAC PAHO/WHO member countries at the time of issuing the 2013 WHO Clinical and Policy Guidelines reveals some important strengths, but also serious gaps that need to be addressed. The most pressing needs are for concerted training initiatives for healthcare providers and strengthening multisectoral monitoring and evaluation of services. A future evaluation of national policies, clinical guidelines, monitoring and evaluation will need to be conducted to measure the progress of the required scaling-up process.

- Abstract
Background: The need to integrate economic and epidemiological aspects in the clinical perspective leads to a proposal for the analysis of health disparities and to an evaluation of the health services and of the new challenges which are now being faced by health system reforms in middle income countries., Objective: To identify the epidemiological changes, the demand for health services and economic burden from chronic diseases (diabetes and hypertension) in a middle income county., Methods: We conducted longitudinal analyses of costs and epidemiological changes for diabetes and hypertension in the Mexican health system. The study population included both the insured and uninsured populations. The cost-evaluation method was used, based on the instrumentation and consensus techniques. To estimate the epidemiological changes and financial consequences for 2014-2016, six models were constructed according to the Box-Jenkins technique, using confidence intervals of 95%, and the Box-Pierce test., Results: Regarding epidemiological changes expected in both diseases for 2014 vs. 2016, an increase is expected, although results predict a greater increase for diabetes, 8-12% in all three studied institutions, (p < .05). Indeed, in the case of diabetes, the increase was 41469 cases for uninsured population (SSA) and 65737 for the insured population (IMSS and ISSSTE). On hypertension cases the increase was 38109 for uninsured vs 62895 for insured. Costs in US$ ranged from $699 to $748 for annual case management per patient in the case of diabetes, and from $485 to $622 in patients with hypertension. Comparing financial consequences of health services required by insured and uninsured populations, the greater increase (23%) will be for the insured population (p < .05). The financial requirements of both diseases will amount to 19.5% of the total budget for the uninsured and 12.5% for the insured population., Conclusions: If the risk factors and the different health care models remain as they currently are, the economic impact of expected epidemiological changes on the social security system will be particularly strong. Another relevant challenge is the appearance of internal competition in the use and allocation of financial resources with programs for other chronic and infectious diseases.

- Abstract
In March 2013, the California Institute for Regenerative Medicine, in collaboration with the NIH Center for Regenerative Medicine, held a 2-day workshop on cell therapies for Parkinson's disease (PD), with the goals of reviewing the state of stem cell research for the treatment of PD and discussing and refining the approach and the appropriate patient populations in which to plan and conduct new clinical trials using stem cell-based therapies for PD. Workshop participants identified priorities for research, development, and funding; discussed existing resources and initiatives; and outlined a path to the clinic for a stem cell-based therapy for PD. A consensus emerged among participants that the development of cell replacement therapies for PD using stem cell-derived products could potentially offer substantial benefits to patients. As with all stem cell-based therapeutic approaches, however, there are many issues yet to be resolved regarding the safety, efficacy, and methodology of transplanting cell therapies into patients. Workshop participants agreed that designing an effective stem cell-based therapy for PD will require further research and development in several key areas. This paper summarizes the meeting., (©AlphaMed Press.)

- Abstract
This is a survey of knowledge, attitudes, and practice regarding HIV testing among 187 female family members affiliated with the Honduran Armed Forces and civilian controls. Prior HIV testing was reported by 45%, and 94% expressed willingness to be tested in the future. Pregnancy was the reason for 73% of prior tests, but only 49% of the 149 women with prior pregnancies reported prior tests. Although most women tested for HIV did so during pregnancy, there appears to be a gap in understanding that the rationale is to help prevent maternal-child transmission at birth or through breast-feeding. Military-affiliated women were more likely to describe themselves as being knowledgeable of HIV/AIDS, 95% versus 82% (p < 0.01), but there were few differences in knowledge between groups. Positive perceptions of confidentiality, test accuracy, and self-awareness of HIV were associated with prior testing. Although these differences may point to HIV/AIDS educational areas that should be emphasized for a particular population, the overall content that should be provided to military or civilian families is the same., (Reprint & Copyright © 2013 Association of Military Surgeons of the U.S.)

- Abstract
The Honduran Ministry of Health (MOH) HIV antiretroviral treatment program began widespread treatment in 2003. We investigated the prevalence of antiretroviral genotypic resistance in specimens collected and archived from HIV-1-infected antiretroviral-naive patients presenting to initiate treatment between 1 July, 2002 and 30 June, 2003 in San Pedro Sula and Tegucigalpa, Honduras. Of 416 specimens collected, 336 (80.8%) were successfully genotyped. All genotypes were HIV-1, group M and 99.1% were subtype B. The prevalence of nucleoside reverse transcriptase inhibitor mutations was 7.7% with M184V and T215F/Y present in 6.0% and 3.0%, respectively. The prevalence of nonnucleoside reverse transcriptase inhibitor mutations was 7.1%. K103N mutations were present in 3.0% of study specimens. The prevalence of major protease inhibitor mutations was 2.7%. Overall, 9.2% of the specimens harbored clinically significant mutations that predict at least intermediate resistance to the Honduran first-line antiretroviral medications. These mutations were more common in San Pedro Sula (14.0%) than in Tegucigalpa (6.5%, p = 0.02). A significant number of patients presenting to initiate antiretroviral therapy in Honduran MOH clinics harbored HIV-1 isolates resistant to the MOH's first-line regimen and resistance varied by region. Further studies to assess the impact of the Honduran antiretroviral program on genotypic resistance are warranted.

- Abstract
Objectives: To evaluate the etiology and characteristics of symptomatic anterior urethral strictures in a large series of men presenting for urologic treatment in an effort to determine the common themes that may influence possible prevention or treatment strategies. Many questions about the origin and features of contemporary anterior urethral stricture disease remain unanswered., Methods: The records of 175 men with symptomatic anterior urethral strictures were reviewed. Data were entered both prospectively by careful patient questioning and retrospectively from detailed chart review. The stricture length, location, and cause were recorded from urologic presentation, before definitive treatment. Posterior strictures from pelvic fracture urethral disruption defects were excluded from this review., Results: A total of 194 strictures were identified in 175 men. Most strictures were idiopathic (65 of 194, 34%) or iatrogenic (63 of 194, 32%); fewer were inflammatory (38 of 194, 20%) or traumatic (28 of 194, 14%). Most involved the bulbar urethra (n = 100, 52%). Pendulous strictures (mean 6.1 cm) were longer on average than those in the fossa navicularis (mean 2.6 cm) or bulb (mean 3.1 cm). Prolonged catheterization (n = 26) and transurethral surgery (n = 25) were common causes of iatrogenic strictures., Conclusions: Our results showed that idiopathic and iatrogenic strictures are surprisingly common. External trauma was a relatively uncommon cause of anterior urethral stricture disease overall. Unnecessary urethral catheterization and repeated urethral instrumentation should be avoided to prevent stricture formation or exacerbation. More study is necessary to determine the origin of anterior urethral stricture disease.

- Abstract
Objective: This study was undertaken to describe demographics and contraceptive familiarity and use among postpartum adolescents in El Salvador., Study Design: Questionnaire-guided interviews were conducted in Spanish with 50 postpartum adolescents at an urban, public hospital in El Salvador. Open-ended questions included assessments of education, partnership status, and contraceptive knowledge and use patterns., Results: The median age of subjects was 17 years, 84% were nulliparous, 80% had partners, and 6% were married. Eighty-four percent of the women reported contraception knowledge and 18% reported contraception use. Educational experience and literacy predicted contraceptive knowledge (P = .008 and .001, respectively), but not use. After delivery and postpartum contraception education, 58% of the subjects stated intention to use contraception. Having a partner and living with him were predictors of intent to use contraception (P = .001 and .002, respectively). Being single negatively predicted intention to use contraception (P = .001)., Conclusion: Education and literacy predicted contraceptive knowledge; however, contraceptive knowledge did not predict contraceptive use. Adolescent contraception use depends on more than just contraceptive knowledge.

- Abstract
A study was conducted in Honduras to address whether military personnel assigned to Joint Task Force-Bravo in Soto Cano, Honduras, routinely acquire parasite infections, and the results were compared with those collected from civilian base workers and the general local population in the nearby towns of Comayagua and La Paz. Results from this study report 21 species of enteric parasites among Hondurans living in Comayagua and La Paz, 13 species among local Hondurans working as base civilian personnel, and 3 species among U.S. military servicemen and women. The most prevalent organism found was Blastocystis hominis, infecting 95 people (35.8% of 265 samples). Prevalence rates in this study are similar to documented reports on parasite transmission in Central American countries and other areas of Honduras. Although preventive protocols for U.S. military "force protection" appear to be effective in controlling transmission, continuous surveillance for enteric parasites is warranted because of the high parasite loads in the populations with which military personnel come into contact.

- Abstract
Primary infection with Pneumocystis carinii usually occurs early in life, and young infants receiving prolonged treatment with high-dose corticosteroids may be at risk for the development of symptomatic disease. Prophylaxis with trimethoprim-sulfamethoxazole is safe and effective and should be considered for such infants, particularly those with underlying airway abnormalities. We describe a 3-month-old immunocompetent infant who developed severe P carinii pneumonia after 6 weeks of high-dose corticosteroid therapy for cervicofacial and airway hemangiomas.

- Abstract
Two mutations in the DJ-1 gene on chromosome1p36 have been identified recently to cause early-onset, autosomal recessive Parkinson's disease. As no information is available regarding the distribution of DJ-1 protein in the human brain, in this study we used a monoclonal antibody for DJ-1 to map its distribution in frontal cortex and substantia nigra, regions invariably involved in Parkinson's disease. Western blotting of human frontal cortex showed DJ-1 to be an abundant protein in control, idiopathic Parkinson's disease, cases with clinical and pathological phenotypes of Parkinson's disease with R98Q polymorphism for DJ-1, and in progressive supranuclear palsy (PSP) brains. We also showed that DJ-1 immunoreactivity (IR) was particularly prominent in astrocytes and astrocytic processes in both control and Parkinson's disease frontal cortex, whereas neurons showed light or no DJ-1 IR. Only occasional Lewy bodies (LBs), the pathological hallmarks of Parkinson's disease, showed faint DJ-1 IR, localized to the outer halo. In preclinical studies we showed that DJ-1 is expressed in primary hippocampal and astrocyte cultures of mouse brain. By 2D gel analysis we also showed multiple pI isoforms for DJ-1 ranging between 5.5-6.6 in both control and Parkinson's disease brains, whilst exposure of M17 cells to the oxidizing agent paraquat was manifested as a shift in pI of endogenous DJ-1 towards more acidic isoforms. We conclude that DJ-1 is not an essential component of LBs and Lewy neurites, is expressed mainly by astrocytes in human brain tissue and is sensitive to oxidative stress conditions. These results are consistent with the hypothesis that neuronal-glial interactions are important in the pathophysiology of Parkinson's disease.

- Abstract
Mutations in a gene on chromosome 1, DJ-1, have been reported recently to be associated with recessive, earlyonset Parkinson's disease. While one mutation is a large deletion that is predicted to produce an effective knockout of the gene, the second is a point mutation, L166P, whose precise effects on protein function are unclear. In the present study, we show that L166P destabilizes DJ-1 protein and promotes its degradation through the ubiquitin-proteasome system. A double mutant (K130R, L166P) was more stable than L166P, suggesting that this lysine residue contributes to stability of the protein. Subcellular localization was broadly similar for both wild type and L166P forms of the protein, indicating that the effect of the mutation is predominantly on protein stability. These observations are reminiscent of other recessive gene mutations that produce an effective loss of function. The L166P mutation has the simple effect of promoting DJ-1 degradation, thereby reducing net DJ-1 protein within the cell.

- Abstract
Context: Myeloperoxidase (MPO), a leukocyte enzyme that promotes oxidation of lipoproteins in atheroma, has been proposed as a possible mediator of atherosclerosis., Objective: To determine the association between MPO levels and prevalence of coronary artery disease (CAD)., Design, Setting, and Patients: Case-control study conducted from July to September 2000 in a US tertiary care referral center, including 158 patients with established CAD (cases) and 175 patients without angiographically significant CAD (controls)., Main Outcome Measures: Association of MPO levels per milligram of neutrophil protein (leukocyte-MPO) and MPO levels per milliliter of blood (blood-MPO) with CAD risk., Results: Leukocyte- and blood-MPO levels were both significantly greater in patients with CAD than in controls (P<.001). In multivariable models adjusting for traditional cardiovascular risk factors, Framingham risk score, and white blood cell counts, MPO levels were significantly associated with presence of CAD, with an OR of 11.9 (95% CI, 5.5-25.5) for the highest vs lowest quartiles of leukocyte-MPO and an OR of 20.4 (95% CI, 8.9-47.2) for the highest vs lowest quartiles of blood-MPO., Conclusions: Elevated levels of leukocyte- and blood-MPO are associated with the presence of CAD. These findings support a potential role for MPO as an inflammatory marker in CAD and may have implications for atherosclerosis diagnosis and risk assessment.

- Abstract
A subset of patients with mitral stenosis have symptoms out of proportion to the resting hemodynamics. Exercise Doppler echocardiography is a useful diagnostic modality to determine which patients are limited by their valve obstruction and would therefore benefit from percutaneous mitral balloon valvotomy. We analyzed 11 patients who showed a peak exercise mean mitral gradient that doubled from baseline or a final gradient of > 15 mm Hg. The mean mitral gradient increased from 7 +/- 2 mm Hg at rest to 19 +/- 6 mm Hg (P < .001) with exercise. All patients reported improvement in symptoms of at least 1 functional class after valvotomy.

- Abstract
Objective: To guide primary care physicians regarding the diagnosis and treatment of poststreptococcal reactive arthritis (PSReA) in adults., Patients and Methods: We retrospectively reviewed an indexed database of all patients evaluated or hospitalized between 1976 and 1998 at Mayo Clinic Rochester and identified 35 patients with the diagnosis of reactive streptococcal arthritis, arthralgia, or arthritides. Twenty-nine patients with the diagnosis of acute rheumatic fever (ARF), septic streptococcal arthritis, or nonspecific reactive arthritis were excluded., Results: PSReA was confirmed in 6 adults (3 women, 3 men; age range, 25-66 years). All patients were symptomatic with polyarthritis and oligoarthritis disproportionate to the objective findings on physical examination. Although all patients had negative throat cultures at the onset of arthritis, increased titers of anti-DNase B and antistreptolysin O confirmed recent streptococcal infection. Antecedent events included pharyngitis in 3 patients (who had received a minimum of a 10-day course of penicillin) and toxic shock syndrome in 1 patient. The latency of onset of arthritis ranged from 4 days to 6 weeks. The arthritic symptoms had a protracted course beyond the typical maximum of 3 weeks described for ARF. Treatment with aspirin did not provide symptomatic relief in any of the patients, whereas the response to therapy with nonsteroidal anti-inflammatory drugs (NSAIDs) was at least partial in all cases. Symptomatic relief occurred in 1 patient who received indomethacin and in 1 patient treated with prednisone. Penicillin prophylaxis was recommended in 1 patient., Conclusion: PSReA should be included in the differential diagnosis of all adult patients presenting with arthritis. Treatment strategies include aspirin, other NSAIDs, and corticosteroids. In adult patients with PSReA, there is no evidence to support the use of penicillin prophylaxis at this time.
