Abstract
Pesticides have been pointed out as hormone disruptors and may significantly affect the prognosis of hormone-dependent diseases such as breast cancer (BC). Here, we investigated the impact of occupational pesticide exposure on systemic cortisol levels in female rural workers diagnosed with BC. Occupational exposure was assessed by interviews with a standardized questionnaire. Plasma samples (112 from pesticide-exposed women and 77 from unexposed women) were collected in the afternoon, outside the physiological cortisol peak, and analyzed by a chemiluminescent paramagnetic immunoassay for the quantitative determination of cortisol levels in serum and plasma. The results from both groups were categorized according to patients' clinicopathological and exposure data. BC pesticide-exposed women presented higher levels of cortisol than the unexposed. Higher cortisol levels were also detected in the exposed group with more aggressive disease (triple-negative BC), with tumors over 2 cm, with lymph node metastases, and with high risk of disease recurrence and death. These findings demonstrated that there is an association between pesticide exposure and BC that affected cortisol levels and correlated to poor disease prognosis.

Abstract
The present outbreak of Human Monkeypox (HMPX) that has begun in May 2022 and has spread across all continents in less than two months has qualitative and quantitative characteristics that make it different from the pattern of human disease previously caused by this virus. It has spread with enormous ease, affects almost exclusively adults, behaves as a sexually transmitted disease and focuses on very specific groups and transmission conditions. The high incidence in the city of Madrid in males that have sex with males (MSM) has allowed us to observe and report the experience with the first 30 cases diagnosed in our institution. Patients presented with febrile symptoms, genital and paragenital skin lesions reminiscent of smallpox, but less extensive and severe. The disease may also cause proctitis, pharyngitis and perioral lesions. The PCR test for diagnostic confirmation has been shown to be very sensitive and effective, not only in skin lesions but also in blood and other fluids such as pharyngeal, rectal exudates and blood. A very high proportion of patients with HMPX also have other sexually transmitted diseases that must be actively detected in this context. The spontaneous evolution of our patients has been good and hospitalization has been practically unnecessary. Transmission to non-sexual cohabitants and health personnel has been nonexistent and the lesions have disappeared in less than 30 days without leaving sequelae and no need for specific antiviral treatment.

Abstract
Cisplatin is an effective antineoplastic agent, but its use is limited by its nephrotoxicity caused by the oxidative stress in tubular epithelium of nephrons. On the other hand, regular exercise provides beneficial adaptations in different tissues and organs. As with many drugs, dosing is extremely important to get the beneficial effects of exercise. Thus, we aimed to investigate the influence of exercise intensity and frequency on cisplatin-induced (20 mg/kg) renal damage in mice. Forty male Swiss mice were divided into five experimental groups (n=8 per group): 1) sedentary; 2) low-intensity forced swimming, three times per week; 3) high-intensity forced swimming, three times per week; 4) low-intensity forced swimming, five times per week; and 5) high-intensity forced swimming, five times per week. Body composition, renal structure, functional indicators (plasma urea), lipid peroxidation, antioxidant enzyme activity, expression of genes related to antioxidant defense, and inflammatory and apoptotic pathways were evaluated. Comparisons considered exercise intensity and frequency. High lipid peroxidation was observed in the sedentary group compared with trained mice, regardless of exercise intensity and frequency. Groups that trained three times per week showed more benefits, as reduced tubular necrosis, plasma urea, expression of CASP3 and Rela (NFkB subunit-p65) genes, and increased total glutathione peroxidase activity. No significant difference in Nfe2l2 (Nrf2) gene expression was observed between groups. Eight weeks of regular exercise training promoted nephroprotection against cisplatin-mediated oxidative injury. Exercise frequency was critical for nephroprotection.

Abstract
OBJECTIVE Following the approval of bezlotoxumab in 2017, studies evaluating its effectiveness in prevention of Clostridioides difficile infection under "real-life" conditions are scarce. METHODS We conducted a retrospective study developed in a large tertiary care hospital describing the use and outcomes of patients with Clostridioides difficile infection (CDI) treated with bezlotoxumab. RESULTS A total of 16 patients were include, all of whom had an episode of CDI with high probability of recurrence and 14 of them had some kind of immunosuppression. Bezlotoxumab was effective in the prevention of CDI recurrence in 11 of the 14 cases in which follow up was possible, without significant side effects. CONCLUSIONS Bezlotoxumab was well tolerated and the incidence of recurrent CDI in a high-risk population for recurrence was only 21.4%.

Abstract
Background There are no clear criteria for antifungal de-escalation after initial empirical treatments. We hypothesized that early de-escalation (ED) (within 5 days) to fluconazole is safe in fluconazole-susceptible candidemia with controlled source of infection. Methods This is a multicenter post hoc study that included consecutive patients from 3 prospective candidemia cohorts (2007–2016). The impact of ED and factors associated with mortality were assessed. Results Of 1023 candidemia episodes, 235 met inclusion criteria. Of these, 54 (23%) were classified as the ED group and 181 (77%) were classified as the non-ED group. ED was more common in catheter-related candidemia (51.9% vs 31.5%; P = .006) and episodes caused by Candida parapsilosis, yet it was less frequent in patients in the intensive care unit (24.1% vs 39.2%; P = .043), infections caused by Nakaseomyces glabrata (0% vs 9.9%; P = .016), and candidemia from an unknown source (24.1% vs 47%; P = .003). In the ED and non-ED groups, 30-day mortality was 11.1% and 29.8% (P = .006), respectively. Chronic obstructive pulmonary disease (odds ratio [OR], 3.97; 95% confidence interval [CI], 1.48–10.61), Pitt score > 2 (OR, 4.39; 95% CI, 1.94–9.20), unknown source of candidemia (OR, 2.59; 95% CI, 1.14–5.86), candidemia caused by Candida albicans (OR, 3.92; 95% CI, 1.48–10.61), and prior surgery (OR, 0.29; 95% CI, 0.08–0.97) were independent predictors of mortality. Similar results were found when a propensity score for receiving ED was incorporated into the model. ED had no significant impact on mortality (OR, 0.50; 95% CI, 0.16–1.53). Conclusions Early de-escalation is a safe strategy in patients with candidemia caused by fluconazole-susceptible strains with controlled source of bloodstream infection and hemodynamic stability. These results are important to apply antifungal stewardship strategies.

Abstract
Abstract
Aims
We currently cannot predict which patients with locally advanced oesophageal adenocarcinoma will be amongst the 15-20% to gain a clinically important response to neoadjuvant therapy (NAT). This pilot study aimed to identify differentially expressed genes from oesophageal adenocarcinoma pre-treatment biopsies between responders and non-responders to NAT and develop methodology for predicting response.
Method
Response to NAT was assessed pathologically using Tumour Regression Grading (TRG). Pre-treatment formalin-fixed paraffin embedded samples were analysed with two nuclease protection assays (EdgeSeq, HTG = Oncology Biomarker Panel (OBP) and Precision Immuno-Oncology Panel (PIP)). Sequencing was performed on the NextSeq500 (Illumina).
Result
Whilst there was no difference in pre-treatment characteristics, responders (TRG1-2, n=26) had significantly better post-treatment pathology and overall survival than non-responders (TRG4-5, n=30). Genes up-regulated in responders were involved in regulating cell cycling, whereas genes up-regulated in non-responders were involved in cytokine signalling and the immune response. Neuronal artificial network models could predict response to NAT with overall accuracy of 73% and 68% for the OBP and PIP, respectively, which is promising considering the small sample size. As no model will be 100% accurate, we developed a model that could take patient's views into consideration with an adjustable probability threshold for classification.
Conclusion
This pilot study informs a biologically sound hypothesis for the basis of response to NAT and suggests prediction from pre-treatment biopsies may be possible using EdgeSeq. We now aim to validate these results in a larger study to inform a bespoke classifier of response to enable delivery of precision therapy.
Take-home message
In oesophageal adenocarcinoma, responders and non-responders to neoadjuvant therapy have different expression profiles. Through using EdgeSeq in larger studies, we may be able to predict which patients will respond to treatment, allowing for delivery of precision therapy.

Abstract
INTRODUCTION BACKGROUND AND AIM Muscle biopsy is still an important exam on the investigation of neuromuscular diseases although data regarding its diagnostic yield can be disappointing. We aimed to analyze the diagnostic yield of muscle biopsies in the pediatric population. PATIENTS AND METHODS We retrospectively analyzed a tertiary Neuropathology laboratory database to identify patients (<18 years old), submitted to muscle biopsy between January 2015 and August 2019. Demographics, clinical presentation, diagnosis, treatment, and follow-up were evaluated. Descriptive statistical analysis was performed. RESULTS One-hundred and six patients were included, 52,8% (n = 56) were male. Median age at biopsy was 6 years (IQR 10 years). Patients were divided into 8 groups, according to clinical diagnostic suspicion: mitochondrial myopathies (n = 29), congenital myopathies (n = 9), inflammatory myopathies (n = 8), muscular dystrophies (n = 7), raised CK values in serum (n = 7), metabolic myopathies (n = 5), weakness /other neuromuscular symptoms (n = 30) and multiple clinical suspicions (n = 11). Biopsy was normal in 50 patients. Of the remaining, 27 displayed specific diagnostic features, with 88,9% (n = 24) allowing a definite diagnosis: muscular dystrophies (n = 7), metabolic myopathies (n = 5), congenital myopathies (n = 4), inflammatory myopathies (n = 4), mitochondrial myopathies (n = 3) and spinal muscular atrophy (n = 1). Histology led to a change of treatment in 4 patients, all diagnosed with inflammatory myopathies. Median length of follow-up was 1 year (IQR 2 years). CONCLUSION Biopsy diagnostic yield was 22,6%, and it was useful either in diagnostic or therapeutic approaches in 35,8%. Although advances of molecular techniques led to a decrease in muscle biopsy indications, it remains an important tool on the diagnosis of neuromuscular diseases.

Abstract
Abstract
Background
Obesity is increasing in younger populations, and is associated with a high cardiovascular (CV) risk, however, it is not clear whether metabolically healthy obesity (MHO) may have a lower CV risk or if it is just an earlier stage of the disease.
Objective
To evaluate the prevalence and CV risk factors associated with MHO in a young population assisted by a Family Health Care unit in a large urban center in Brazil.
Methods
A cross-sectional population study for CV risk assessment in adults aged 20-50 years old from a FHC unit in Rio de Janeiro. Demographic, anthropometric data and CV risk factors were recorded. All underwent office blood pressure (OBP) measurements, laboratory evaluation (lipid and glycidic profile). Obesity was defined as a BMI ≥ 30 kg/m2 and MHO are those who have less than 3 of the following criteria: hypertension, diabetes, total cholesterol ≥ 200 mg/dL, HDL<40 mg/dL (men) and 50 mg/dL (women), triglycerides>150 mg/dL and increased waist circumference.
Results
A total of 632 individuals were evaluated (60% female; mean age 37 ± 9 years). The prevalence of obesity was 26%, of which 73% were classified as MHO. Obeses are older, with a higher prevalence of physical inactivity (51% vs 41%, p = 0.03), hypertension (44% vs 19%, p < 0.001), dyslipidemia (50% vs 36%, p = 0.002) and diabetes (7% vs 2%, p = 0.001) with higher systolic OBP. MHO compared to unhealthy ones are significantly younger and smoke less. Despite being obese, they have lower BMI (33.6 vs 35.2 kg/m2, p = 0.02) and abdominal circumference (102 vs 110 cm, p = 0.03), with lower diastolic BP.
Conclusions
MHO was more prevalent in this young population and seems to have a lower CV risk, however it is not clear whether these younger and less obese individuals are only at an earlier stage of the disease. Perhaps the CV diseases onset is postponed for a few years. Even so, these individuals should not be excluded from public health policies as a form of primary prevention.
Key messages
In this young population, MHO was more prevalent and presented a lower CV risk. The follow-up of MHO will show if they are really healthy or if they are at an early stage of the disease.

Abstract
Abstract
The objective of this study is to develop a complete economic evaluation of 3 diagnostic techniques for interproximal radiographic, comparing the conventional radiographic technique, direct (CMOS) and indirect (PSP) digital techniques in the diagnosis of dental caries, from the perspective of SESC/Brazil (Social Trade Service). A complete cost-minimization economic assessment was performed. Initially, a systematic review was performed and it was verified that the accuracy for the diagnosis is similar between the techniques. The direct medical costs (related to the technique) were estimated by the bottom-up technique, taking into account the value of the clinical hours of the professionals, equipments and materials used. The time horizon was 10 years. The values were discounted at 3% per year, and a sensitivity analysis was prepared into two scenarios (one more pessimistic with costs 20% higher than estimated and one more optimistic with costs 20% lower). Direct digital radiography proved to be the option with the lowest cost (US$ 1.16), followed by semi-direct (US$ 1.35) and conventional (US$ 1.47). Conventional radiography presented the highest cost for the period (US$ 74,943.65), and the use of digital radiographs could promote savings of US$ 6,000.59 and US$ 15,448.35, if used by the semi-direct and direct method. respectively. Regarding the sensitivity analysis, in the most optimistic scenario of the time horizon there would be savings of US$ 4,800.47 (semi-direct digital) to US$ 12,446.09 (direct digital) compared to the traditional technique (films). In the most pessimistic scenario, these values vary in savings over the time horizon from US$ 7,200.71 (semi-direct) to US$ 18,538.02 (direct). It is concluded that the direct radiographic technique was the most cost effective and its incorporation in the SESC units is suggested.
Key messages

Abstract
The partial or complete loss of chlorophylls, or albinism, is a rare phenomenon in plants. In the present study, we provide the first report of the occurrence in albino Delonix regia seedlings and describe the morpho-physiological changes associated with albinism. Wild-type (WT) and albino seedlings were characterized. Leaflets samples were processed following common procedures for analysis with light, scanning and transmission electron microscopy. The chlorophyll a fluorescence parameters and the carbohydrate, lipid and soluble protein content were also determined in leaf and cotyledon samples of both albino and WT seedlings. Albino seedlings showed reduced growth. They also had lower chlorophyll and protein content in foliar tissues than WT seedlings, in addition to lower concentrations of lipids and carbohydrates stored in cotyledons. The chloroplasts of albino seedlings were poorly developed, with an undefined internal membrane system and the presence of plastoglobules. Wild-type seedlings had a uniseriate and hypoestomatic epidermis. The mesophyll was dorsiventral, consisting of a layer of palisade parenchyma and two to four layers of spongy parenchyma. In albino seedlings, the spongy parenchyma was compact, with few intercellular spaces, and the thickness of the mesophyll was larger, resulting in increased thickness of the leaf blade. Albino seedlings had higher stomatal density and number of pavement cells, although the stomata had smaller dimensions. In addition to the partial loss of chlorophylls, albino D. regia showed changes at physiological and structural levels, demonstrating the crucial nature of photosynthetic pigments during the development and differentiation of plant leaf tissues/cells.

Abstract
B cells orchestrate pro-survival and pro-apoptotic inputs during unfolded protein response (UPR) to translate, fold, sort, secrete and recycle immunoglobulins. In common variable immunodeficiency (CVID) patients, activated B cells are predisposed to an overload of abnormally processed, misfolded immunoglobulins. Using highly accurate transcript measurements, we show that expression of UPR genes and immunoglobulin chains differs qualitatively and quantitatively during the first 4 h of chemically induced UPR in B cells from CVID patients and a healthy subject. We tested thapsigargin or tunicamycin as stressors and 4-phenylbutyrate, dimethyl sulfoxide and tauroursodeoxycholic acid as chemical chaperones. We found an early and robust decrease of the UPR upon endoplasmic reticulum (ER) stress in CVID patient cells compared to the healthy control consistent with the disease phenotype. The chemical chaperones increased the UPR in the CVID patient cells in response to the stressors, suggesting that misfolded immunoglobulins were stabilized. We suggest that the AMP-dependent transcription factor alpha branch of the UPR is disturbed in CVID patients, underlying the observed expression behavior.

Abstract
Tryptophan participates on several physiological mechanisms of the neuroendocrine-immune network and plays a critical role in macrophages and lymphocytes function. This study intended to evaluate the modulatory effects of dietary tryptophan on the European seabass (Dicentrarchus labrax) immune status, inflammatory response and disease resistance to Photobacterium damselae piscicida. A tryptophan deficient diet (NTRP); a control diet (CTRL); and two other diets supplemented with tryptophan at 0.13% (TRP13) and 0.17% (TRP17) of feed weight were formulated. Fish were sampled at 2 and 4 weeks of feeding and the remaining were i.p. injected with Phdp (3 × 106 cfu/fish) at 4 weeks and the inflammatory response (at 4, 24, 48 and 72 hours post-infection) as well as survival were evaluated. Results suggest that fish immune status was not altered in a tryptophan deficient scenario whereas in response to an inflammatory insult, plasma cortisol levels increased and the immune cell response was compromised, which translated in a lower disease resistance. When dietary tryptophan was offered 30% above its requirement level, plasma cortisol increased and, in response to bacterial infection, a decrease in lymphocytes, monocytes/macrophages and several immune-related genes was observed, also compromising at some degree fish disease resistance.

Abstract
Tenacibaculosis, caused by Tenacibaculum maritimum, continues to inflict substantial losses among cultured marine species, particularly in the Senegalese sole. However, the immune mechanisms in fish involved in fighting against this disease are still poorly understood. Thus, the present study aimed to investigate the skin mucus's terminal carbohydrate composition, several immune-related enzymes (i.e. lysozyme, peroxidase, proteases and antiproteases), the haemolytic activity of complement and the bactericidal activity in the skin mucus and plasma of the Senegalese sole in a time-course study following a bath challenge with T. maritimum. The haematological profile and the kinetics of cell migration post-infection were also considered. The bath challenge induced slight variations in the terminal carbohydrate composition of Senegalese sole skin mucus. In general, results from this study showed a delay in the mucosal immune response compared to that found at the systemic level (i.e. blood and plasma). For instance, a significant increase in the skin mucus's lysozyme, complement, protease and antiprotease activities were observed at the end of the experiment (14 d post-challenge). Interestingly, the higher activity of these enzymes could be related to the skin mucus's bactericidal capacity and haemolytic complement activity, suggesting that these enzymes play an important role in the defence against Gram-negative bacteria. The haematological profile revealed a significant increase in circulating neutrophils in challenged fish after 48 and 72 h, which was positively correlated to the increments observed in peroxidase and lysozyme activities, respectively, in the plasma of challenged fish at the same time. Although the route of entry and the survival strategy of T. maritimum are still not fully elucidated, results from the present study will contribute to this endeavour through the study of the mucosal immune responses of fish against this particular pathogen.

Abstract
Background We aim to evaluate the presence of histological artefacts in the surgical margins of human oral fibro-epithelial hyperplasias excised with lasers of different wavelengths, and also electrosurgical scalpel and cold scalpel. Moreover, we aim to determine if some of these instruments could impair the normal histological diagnosis of these lesions. Material and Methods We included 130 consecutive surgical samples of 80 females and 50 males (mean age of 53.82±16.55) with a histological diagnosis of an oral benign fibrous-epithelial hyperplasias. The samples were categorized into 6 groups according to the type of instrument used: CO2 laser group, diode laser group, Er:YAG laser group, Nd:YAG laser group, electrosurgical scalpel group and cold scalpel group. Histological instrument-induced changes were microscopic evaluated and related with clinical and pathological variables. Results The instrument with highest tissue damage extension (TDE) was the electrosurgical scalpel (1002.2µm±434.92), followed by diode laser (913.73 µm±322.45), Nd:YAG (899.83µm±327.75), CO2 laser (538.37µm±170.50), Er:YAG laser (166.47µm±123.85), and at last with fewer alterations the cold scalpel group (2.36µm±7.27) (P< 0.001). The most regular incision was observed in CO2 laser group, followed by Er:YAG laser, Nd:YAG laser, electrosurgical scalpel and diode laser group with the less regular incision using cold scalpel as comparison (P< 0.001). A correlation was found between the incision score and TDE (P< 0.001). Regarding histological diagnosis, no case showed any limitation of diagnosis related with the use of any instrument evaluated. Conclusions Our results suggest that lasers can be used for the excision of oral benign fibrous-epithelial hyperplasias, without hispathological diagnosis limitations, as long as the physical properties of each laser are known and respected. Er:YAG laser have shown to be a laser with few tissue damage extension and with good incision regularity, been a possible instrument of choice for the surgical removal of these lesions. Key words:CO2 laser, diode laser, Er:YAG laser, Nd:YAG laser, oral mucosa.

Abstract
Phytophthora species secrete several classes of effector proteins during interaction with their hosts. These proteins can have multiple functions including modulation of host physiology and immunity. The RxLR effectors have the ability to enter plant cells using the plant machinery. Some of these effectors have been characterized as immunity suppressors; however, very little is known about their functions in the interaction between Phytophthora parasitica and its hosts. Using a bioinformatics pipeline, we have identified 172 candidate RxLR effectors (CREs) in the isolate IAC 01_95 of P. parasitica. Of these 172 CREs, 93 were found to be also present in eight other genomes of P. parasitica, isolated from different hosts and continents. After transcriptomics and gene expression analysis, we have found five CREs to be up-regulated in in-vitro and in-planta samples. Subsequently, we selected three CREs for functional characterization in the model plant Nicotiana benthamiana. We show that PpRxLR2 is able to completely suppress INF-1-induced cell death, whereas PpRxLR3 and PpRxLR5 moderately suppressed N. benthamiana immunity in a less-extensive manner. Moreover, we confirmed the effector-triggered susceptibility activity of these proteins after transient transformation and infection of N. benthamiana plants. All three CREs enhanced virulence of P. parasitica during the interaction with N. benthamiana. These effectors, in particular PpRxLR2, can be targeted for the development of biotechnology-based control strategies of P. parasitica diseases.

Abstract
Immune responses relies on an adequate provision of multiple nutrients that sustain the synthesis of key effector molecules. These needs are depicted in the already reported increase of circulating free amino acids in fish under stressful conditions. Since aquaculture and the inherent fish welfare are an emergent call, the immunomodulatory effects of amino acids on gut- and skin-associated lymphoid tissues of the European seabass (Dicentrarchus labrax) were studied under unstressed conditions and after an inflammatory insult. To achieve this goal, fish were distributed in duplicate tanks (fifteen fish per tank) and were fed for 14 days with methionine or tryptophan-supplemented diets at 2× dietary requirement level (MET and TRP, respectively) or a control diet meeting the amino acids requirement levels (CTRL). Afterwards, samples of skin and posterior gut were collected from 6 fish per dietary treatment for the assessment of the immune status while the remaining animals were intraperitoneally-injected with inactivated Photobacterium damselae subsp. piscicida and subsequently sampled either 4 or 24 h post-injection. The immune status of both mucosal surfaces was poorly affected, although a tryptophan effect was denoted after bacterial inoculation, with several immune-related genes up-regulated in the gut at 4 h post-injection, which seems to suggest a neuroendocrine-immune systems interaction. In contrast, skin mucosal immunity was inhibited by tryptophan dietary supplementation. Regarding methionine, results were often statistically non-significant, though increasing trends were denoted in a few parameters. Overall, dietary methionine did not significantly affect neither gut nor skin immunity, whereas tryptophan supplementation seems to induce modulatory mechanisms that might be tissue-specific.

Abstract
IntroductionDepressive Symptoms (DS) generate a public and economic health problem, with decreasing productivity, labour market withdrawal and increased demand for health services. Studies show that in hospitalized patients, DS rates are higher than in the general population, in medical practice, however, they are under diagnosed or under-treated. Consultation Liaison Psychiatry (LP) can prevent aggravation of the psychic symptoms by early identification of them and by integration of psychiatry with the other medical specialties.ObjectivesTo estimate the prevalence of DS and associated factors in inpatients and the frequency of consultation LP.MethodsA cross-sectional study was carried out in March 2016, with 87 patients hospitalized in the clinical and surgical wards at the University Hospital (Sergipe/BR), through two instruments: (1) Structured Questionnaire prepared by the authors, (2) Beck Depression Inventory (BDI). Data analysis through descriptive and analytical statistics with final step of logistic regression.ResultsThe prevalence of DS were 54%, of which 24% correspond to moderate and severe symptoms, and only 3.4% of the patients had a LP. In Logistic Regression, the only factor associated with DS was the reason for hospitalization. Clinical causes (87.2%) were 9.24 times more likely to develop DS than surgical causes.ConclusionsResults suggest a high prevalence of inpatients with some psychic symptom. Physicians did not detect these symptoms and, therefore, LP request was low. These data reinforce the importance of LP for early identification of DS that should be stimulated during medical training.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
BACKGROUND Tuberculosis (TB) is a major global health problem, and during the last 20 years, industrialised countries have shown similar patterns in TB notifications: decreasing TB incidence in native populations and increasing incidence in foreign-born populations. OBJECTIVES To characterise risk factors associated with TB among native- and foreign-born TB patients in Portugal and identify barriers to the management of foreign cases. METHODS Analysis of the data from the national tuberculosis surveillance system and data from an online survey of physicians managing TB cases in the country. RESULTS Risk factors in the two populations differed. Foreign-born patients were younger, less likely to use drugs or alcohol and had fewer comorbidities. They were also more likely to be human immunodeficiency virus positive, to be employed and to be homeless/living in shelters. The outcome of the disease and the time to diagnosis were not significantly different between the two populations. The most important barriers to the management of foreign-born TB cases were language and fear of deportation. CONCLUSIONS As there are significant differences between the two populations, different TB control strategies should be implemented in the two populations.

Abstract
Tenacibaculum maritimum, the aetiological agent for marine tenacibaculosis, is one of the most significant pathogens that threaten Senegalese sole, Solea senegalensis (Kaup), aquaculture. Because no immersion challenge with T. maritimum has been reported previously for this flatfish species, this study aimed to optimize bacterial yields as well as to establish a challenge model for tenacibaculosis induction. Several approaches were performed to optimize bacterial culture conditions, including treatment with non-ionic surfactants, detergents, cellulase hydrolysis and strong shaking. A prolonged bath challenge was performed for 24 h under two different temperatures, 16 and 23 °C. Moreover, mucus and plasma bactericidal activities against T. maritimum were also assessed. Culturing bacteria with strong shaking and continuous shaking provided suitable culture conditions to obtain higher bacterial yields without aggregation and fluctuation, contrary to most other treatments that showed a huge amount of bacterial aggregates. A prolonged bath method for 24 h, without skin or gill scarification, was considered suitable for disease induction with high mortality rates. Moreover, data regarding mucus and plasma bactericidal activities suggested that there is a lack of host innate immune response against T. maritimum or that this particular pathogen presents evading strategies against Senegalese sole.

Abstract
Essential oils (EOs) extracted from Lavandula luisieri and Cymbopogon citratus were tested for their antifungal activity against ten clinical isolates of dermatophytes isolated from cases of tinea pedis. Inhibition of conidial germination and antifungal drug/EO combination assay were tested on two ATCC reference strains of Trichophyton rubrum and Trichophyton mentagrophytes. EOs were characterised by high amount of oxygenated monoterpenes in their composition. Strong antifungal activity was observed for the majority of clinical strains, and fungicidal activity was demonstrated. Positive interaction between L. luisieri EO combined with terbinafine was observed against terbinafine-resistant strain (Tr ATCC MYA-4438). Significative reduction of the germination was observed above 100 μg mL-1. Both oils were safe to macrophage mammalian cells at tested concentration. This study describes the antifungal activity of L. luisieri and C. citratus EOs against dermatophytes, which could be useful in designing new formulations for topical treatments.

Abstract
Oocytes resume meiosis spontaneously when subjected to in vitro maturation (IVM). Cyclic adenosine monophosphate (cAMP) elevating agents have been used for artificial blocking of meiotic resumption (pre-IVM) to allow the oocyte to prepare for maturation, potentially increasing its developmental competence. However, the ultrastructural effects of this pharmacological approach on oocytes and embryos remain to be addressed. We assessed the effects of pre-IVM with cAMP modulators in oocytes (10 for each group) at the end of IVM and in blastocyst (10 for each group) after 7 days of culture. Cumulus-oocyte complexes (COC) were subjected to pre-IVM for 2 h with forskolin (Sigma, St. Louis, MO, USA; 100 μM) and 3-isobutyl-1-methylxanthine) (IBMX, Sigma, 500 μM) followed by 24 h of IVM with FSH-enriched media (IVF Vet Solutions, Adelaide, Australia). Simultaneously, another group of COC was subjected to conventional IVM (con-IVM) for 24 h (EmbryoTransBiotech, Copenhagen, Denmark) with BSA (4 mg mL–1, Sigma), gentamycin (50 mg mL–1), and FSH (0.1 IU mL–1). Matured oocytes were collected for qualitative ultrastructural analysis or followed to IVF. The morphology was carefully evaluated on serially sectioned oocytes and embryos, where each serial section (~60.2-μm section per oocyte/embryo) was analysed under light microscopy. Subsequently, the equatorial section from each oocyte and the section giving the optimal representation of the inner cell mass in each blastocyst was re-embedded and sectioned for electron microcopy as previously described (Hyttel and Madsen 1987 Acta Anat. 129, 12–14). Blastocyst rates did not differ between groups. Ultrastructural analyses revealed subtle ultrastructural differences between pre-IVM and con-IVM conditions. In both groups, oocytes had matured to metaphase II. The perivitelline space of pre-IVM oocytes was significantly narrower than con-IVM. The cytoplasmic vesicles were more abundant and globally distributed in pre-IVM oocytes, whereas at con-IVM a vesicle-free periphery of the ooplasm was frequent, except for cortical granules and clusters of mitochondria associated with smooth endoplasmic reticulum (SER). We observed typical hooded mitochondria and cortical granules either clustered in the periphery or solitarily distributed in the cortical ooplasmic region for both groups. In the blastocysts, differences were noted with respect to especially distribution of ribosomes. In pre-IVM blastocysts, ribosomes were mostly organised in free clusters (polysomes) and peripherally located in cells of the inner cell mass. Con-IVM blastocysts showed ribosomes preferentially associated with the rough ER and often associated with mitochondria. Lipid droplets and rounded mitochondria were observed in both groups as well as apically located tight junctions and desmosomes between adjacent trophectoderm (TE) cells. Pleomorphic and elongated mitochondria were abundant in the TE of pre-IVM blastocysts, whereas the mitochondrial population was more homogenous at con-IVM. These findings suggest that pre-IVM for 2 h affects oocyte and blastocyst ultrastructure.

Abstract
The skin is the largest organ of the human body and its functions include protection, thermoregulation sensation and secretion. Significant advances in our understanding of how the morphology and physiology of the skin contribute to the skin's barrier role have been achieved in recent years. The aim of this review is to summarize the principal approaches which have been used to assess variation in skin barrier function with anatomic site, age, gender, and ethnicity. The methods discussed include trans-epidermal water loss (TEWL) measurement, assessment of corneocyte size, response to vasoactive compounds and attenuated total reflectance Fourier transform infrared (ATR-FTIR) interrogation of skin. The utility of the various methods is considered and the most important findings in the literature to date are highlighted.
