Abstract
Boron nitride nanotube peapods (BNNT-peapod) are composed of linear chains of C60
molecules encapsulated inside boron nitride nanotubes, they were first synthesized in 2003.
In this work, we investigated the mechanical response and fracture dynamics of BNNT-
peapods under ultrasonic velocity impacts (from 1 km/s up to 6 km/s) against a solid target.
We carried out fully atomistic reactive molecular dynamics simulations using a ReaxFF
forcefield. We have considered the case of horizontal and vertical shootings. Depending on
the velocity values, we observed nanotube bending, nanotube fracture, and C60 ejection.
Furthermore, the nanotube unzips for horizontal impacts at certain speeds, forming bi-layer
nanoribbons "incrusted" with C60 molecules. The methodology used here is applicable to
other nanostructures. We hope it motivates other theoretical investigations on the behavior
of nanostructures at ultrasonic velocity impacts and aid in interpreting future experimental
results. It should be stressed that similar experiments and simulations were carried out
on carbon nanotubes trying to obtain nanodiamonds. The present study expands these
investigations to include BNNT.

Abstract
The advent of graphene has renewed the interest in other 2D carbon-based materials. In particular, new structures have been proposed by combining hexagonal and other carbon rings in different ways. Recently, Bhattacharya and Jana have proposed a new carbon allotrope, composed of different polygonal carbon rings containing 4, 5, 6, and 10 atoms, named tetra-penta-deca-hexagonal-graphene (TPDH-graphene). This unusual topology results in interesting mechanical, electronic, and optical properties with several potential applications, including UV protection. Like other 2D carbon structures, chemical functionalizations can be used to tune TPDH-graphene's physical/chemical properties. In this work, we investigate the hydrogenation dynamics of TPDH-graphene and its effects on its electronic structure, combining DFT and fully atomistic reactive molecular dynamics simulations. Our results show that H atoms are mainly incorporated on tetragonal ring sites (up to 80% at 300 K), leading to the appearance of well-delimited pentagonal carbon stripes. The electronic structure of the hydrogenated structures shows the formation of narrow bandgaps with the presence of Dirac cone-like structures, indicative of anisotropic transport properties.

Abstract
UNLABELLED We study the microbiome of sea water collected from two locations of the Barbadian coral reefs. The two sites differ in several environmental and ecological variables including their endogenous benthic community and their proximity to urban development and runoffs from inland watersheds. The composition of the microbial communities was estimated using whole genome DNA shotgun sequencing with adjuvant measurements of chemical and environmental qualities. Although both sites exhibit a similar degree of richness, the less urbanized site (Maycocks reef at Hangman's Bay) has a strong concentration of phototrophs whereas the more urbanized location (Bellairs reef at Folkstone) is enriched for copiotrophs, macroalgal symbionts and marine-related disease-bearing organisms from taxa scattered across the tree of life. Our results are concordant with previous profiles of warm ocean surface waters, suggesting our approach captures the state of each coral reef site, setting the stage for longitudinal studies of marine microbiome dynamics in Barbados.

Abstract
Abstract
Aim
Extended retromuscular dissection performed for abdominal wall reconstruction in complex abdominal wall repair has progressively exposed the anatomy between the peritoneal layer and abdominal wall muscles. This study aimed to assess the morphology and distribution of preperitoneal fat in a cadaveric model.
Material and methods
Thirty frozen cadaver torsos were dissected by posterior component separation. The shape of the preperitoneal fat was identified, and the dimensions and more significant distances were calculated.
Results
The results showed that the preperitoneal fat resembles a trident, exists along the midline under the linea alba, and expands in the epigastric area into a rhomboid shape. The fatty triangle was found to be a part of this rhomboid. The mean rhomboid area was 35 cm2. Caudally, the midline preperitoneal fat widened under the arcuate line to reach the Retzius space. Laterally, the Bogros space communicated the root of the trident with the paracolic gutters, Toldt's fascia, and pararenal fats, forming the lateral prong of the trident. The mean width of the midline prong at the umbilicus was 2.8 cm. It was easier to tear the peritoneum outside the area reinforced by the fatty trident.
Conclusions
The concept of preperitoneal fatty trident may be of practical assistance to perform various hernia procedures, from the simple ventral hernia repair to the more complex preperitoneal ventral repair or posterior component separation techniques. The consistency of this layer allows us to follow our plane between the peritoneum and muscle layers to extend the preperitoneal dissection.

Abstract
Abstract
Aim
The importance of an appropriate patient optimization (botulin toxin and pneumoperitoneum) and adequate surgical technique is highlighted.The possibility of intraoperative monitoring of the nerves that may be injured during posterior component separation is explained
Material and methods
We present a 74 years old man, past smoker, with history of hypertension, steatohepatitis and chronic bronchopathy
Results
This is a disastrous but unfortunately not so uncommon story of a failed repair of a simple umbilical hernia with 3 previous unsuccessful attempts of repair with and without mesh. After the last surgery the patient developed a giant incisional hernia with loss of domain. Optimization consisted of improving nutritional status, respiratory physiotherapy, botulin toxin and pneumoperitoneum. The surgery was made using previous skin scar. After dissecting the retrorectus space, a posterior component separation was made with the aid of monitoring the nerves that come to innervate the rectus abdominis. An overextended overlapped was obtained. A patch of absorbable mesh was used to completely close the peritoneum. A combination of absorbable and permanent synthetic mesh was used as giant reinforcement of the visceral sac. The only points of fixation were the Cooper Ligaments. The patient had a satisfactory recovery without complications and was discharged on the 8th postoperative day.
Conclusions
Loss of domain incisional hernias is a real surgical challenge. The combination of a good preoperative strategy (preoperative neumoperitoneum) and surgical technique (TAR and pannniculectomy) gives a great opportunity to solve very complex cases of incisional hernia.

Abstract
Abstract
The best approach for lateral incisional hernia is not known. Among these difficult hernias, those arising from iliac crest harvesting can be particularly challenging. The objective of this video is to illustrate the surgical approach of a multirecurrent case with the need of adding a posterior component separation
A 70 years old woman with 2 previous attempts of repair was referred to our center. With the patient in a 45 degrees lateral decubitus, a posterior lumbar approach was initiated through the previous scar. The retromuscular preperitoneal plane was accessed with difficulty due to previous meshes in the subdiaphragmatic, iliac and posterior areas. A big tear on the medial peritoneum changed our plan to add a posterior component separation. As we did not want to enlarge the lumbar incision to denervate more the lateral abdominal wall, we decided to make an accessory midline incision. Probably, an ETEP approach could have been better even before making the posterior incision. Once the retromuscular plane was dissected, the hole in the peritoneum could be closed. The reconstructive phase consisted in making a taco configuration using the combination of a permanent and absorbable mesh.
We have learned from this case, that an eTEP dissection of the retromuscular plane could have helped to avoid the accessory midline incision. It is also important to consider the potential iatrogenic denervation we could add in case of enlargement of the incision.

Abstract
BackgroundMental disorders constitute a serious and underestimated problem in Latin America and they could have worse features in comparison with Europe or North America (1); that was the case even before the COVID-19 epidemic ensued in 2020.ObjectivesThe objective of this study was to determine the factors associated with the occurrence of mental health disorders (MHD) in patients with autoimmune rheumatic disease (ARD) from Perú, a high COVID-19 incidence country.MethodsPatients with ARD from a single center (Hospital Guillermo Almenara -EsSalud, Lima-Perú) were included during the first and second waves of the COVID-19 pandemic (March to November 2020). Interviews, medical records reviews, and an electronic survey were performed. MHD explored were depression (assessed with the Patient Health Questionnaire 9: PHQ-9), anxiety (ascertained with the Generalized Anxiety Disorder-7: GAD-7) and post-traumatic stress disorder: PTSD (evaluated with the Event Scale-Revised: IES-R). Variables examined were sociodemographic (age, gender, educational level, marital status, living alone, job status, religiosity), previous diagnosis and treatment for mental disorders, living with a COVID-19 patient, COVID-19 diagnosis (current or past), fear of COVID-19 (assessed with the COVID-19 Scale: FCV-19S) and the ARD type. Multivariable logistic regression models using backward elimination procedure were performed to determine the variables associated with depression, anxiety, and PTSD.

The most frequent diagnosis was rheumatoid arthritis in 446(48.8%) patients followed by systemic lupus erythematosus in 279 (30.6%). Depression, anxiety, and PTSD were observed in 128 (14.0%), 112 (12.30%) and 485 (53.1%) patients, respectively. In the multivariable analyses, previous treatment for mental disorders and fear of COVID-19 were associated with depression: OR=2.35 (95% CI 1.37-4.03; p=0.002) and OR=1.07 (95% CI 1.05-1.10; p<0.001) respectively; also with anxiety: OR= 2.42 (95% CI 1.37-4.26; p=0.002) and OR=1.09 (95% CI 1.06-1.12; p <0.01) and with PSTD: OR=2.42 (95% CI 1.39-4.21;p=0.002) and OR=1.41 (95% CI=1.11-1.17; p<0.001). A diagnosis of COVID-19 was associated with PTSD: OR=1.75 (95% CI 1.06-2.89, p=0.028), while being single was associated with a decreased probability of PTSD occurrence: OR=0.57 (95% CI=0.35-0.96; p=0.03). Finally, having a high educational level was associated with less anxiety: OR=0.43 (95% CI=0.82-0.21; p=0.009), for university /postgraduate studies and OR=0.52 (CI 95%=0.28-0.95; p=0.032) for secondary studies.ConclusionFear of COVID-19 and previous treatment for mental disorder were associated with all MHD explored on our ARD patients during the COVID-19 pandemic.References[1]Zhang S.

Abstract
OBJECTIVE To investigate the frequency and perform a qualitative analysis of spin bias in publications of controlled trials assessing the therapeutic use of cannabis derivatives and their synthetic analogues. STUDY DESIGN AND SETTING Meta-epidemiologic study carried out at the Universidade Federal de São Paulo, Brazil. RESULTS A total of 65 publications with at least one efficacy primary outcome were considered. The results analysis for the primary outcome indicated statistically significant effects in 44.6% (29/65) of the publications, and 70.7% (45/65) of the conclusions were considered favorable to the intervention. Among the 36 publications that found statistically nonsignificant results for the primary outcome, 44.4% (16/36) presented conclusions favorable to or recommending the intervention, which represents spin bias according to the definition adopted in this study. Qualitative analysis of the 16 studies with spin bias showed selective outcomes reporting (elevating secondary outcomes that had positive results or reporting only subgroup results), deviations from the planned statistical analysis, and failure to consider or report uncertainty in the estimates of treatment effects. CONCLUSION The frequency of spin bias among publications of controlled trials with statistically nonsignificant results assessing the therapeutic use of cannabis derivatives and their synthetic analogues reached 44.4%. When not observed by readers, such deviation can lead to misconduct in clinical practice through the adoption of interventions that are not effective or whose effectiveness is uncertain.

Abstract
Infectious diseases are one of the major drivers of coral reef decline worldwide. White plague-like disease (WPL) is a widespread disease with a complex etiology that infects several coral species, including the Brazilian endemic species Mussismilia braziliensis. Gene expression profiles of healthy and WPL-affected M. braziliensis were analyzed in winter and summer seasons. The de novo assembly of the M. braziliensis transcriptome from healthy and white plague samples produced a reference transcriptome containing 119,088 transcripts. WPL-diseased samples were characterized by repression of immune system and cellular defense processes. Autophagy and cellular adhesion transcripts were also repressed in WPL samples, suggesting exhaustion of the coral host defenses. Seasonal variation leads to plasticity in transcription with upregulation of intracellular signal transduction, apoptosis regulation, and oocyte development in the summer. Analysis of the active bacterial rRNA indicated that Pantoea bacteria were more abundant in WPL corals, while Tistlia, Fulvivirga, and Gammaproteobacteria Ga0077536 were more abundant in healthy samples. Cyanobacteria proliferation was also observed in WPL, mostly in the winter. These results indicate a scenario of dysbiosis in WPL-affected M. braziliensis, with the loss of potentially symbiotic bacteria and proliferation of opportunistic microbes after the start of the infection process.

Abstract
OBJECTIVE To determine the feasibility,tolerability, and safety of the ultrasound assessment of tubal patency using foam as contrast. METHODS This was a prospective multicenter study of 915 infertile nulliparous women scheduled for sonohysterosalpingography with foam instillation (HYFOSY) for tubal patency testing as a part of the fertility workup. Clinical and sonographic data were recorded into a web-shared database. Tubal patency, cervical catheterization, pain during the procedure and post-procedural complications were collected. Patients reported discomfort or pain experienced during the procedure with a visual analogue scale (VAS) score. RESULTS Nine hundred fifteen women were included in the final analysis. Median age was 34 (range, 21-45) years and median body mass index was 23 (range, 16-41) kg/m2. Of 839 women, only 8(0.95 %) cases were abandoned due to impossibility of introducing the intracervical catheter. Most of the cervical os were easily cannulated with either paediatric nasogastric probes or special catheter for intrauterine insemination / sonohysterosalpingography 688/914(75.3 %). With a median instillation of 4 mL (range 1-16) of foam, both tubes were identified in 649/875 (70.9 %) patients, while unilateral patency was observed in 190/875 (20.8 %). Only 36/875 (3.9 %) of the women had bilateral tubal obstruction. The median VAS score for perception of pain during HyFoSy examination was 2 (range 0-10), and only 17 (1.9 %) of women reported severe pain (VAS ≥ 7). Pain was unrelated to tubal patency or tubal blockage. Unexpectedly, difficult cervical catheterizations that needed tenaculum, were more likely associated with mild pain during procedure [nasogastric probe group 176/289 (70.9 %) vs. insemination catheter group 166/399 (41.6 %) vs. tenaculum group 190/218(87.2 %) p < 0.001]. Finally, among 915 patients, we only noticed 3 (0.32 %) complications of the technique: two vasovagal episodes and a mild urinary infection. CONCLUSION HYFOSY is a feasible, well-tolerated and safe technique for the evaluation of tubal patency in infertile women.

Abstract
OBJECTIVE To determine whether differences exist in the rate of levator ani muscle (LAM) avulsion between women who had undergone either Malmström vacuum delivery (MVD) or Kielland forceps delivery (KFD), allowing for potential confounding factors. METHODS This was a prospective observational study of nulliparous women undergoing instrumental delivery using Malmström vacuum extractor or Kielland forceps, at two hospital centers in Spain. Fetal head position (anterior, posterior or transverse) and fetal head station (low or mid) were assessed by ultrasound and digital examination, respectively. Avulsion was defined on tomographic ultrasound imaging as an abnormal insertion of the LAM in the three central slices from the plane of minimal hiatal dimensions. RESULTS In total, 414 patients were included in the study (212 MVD and 202 KFD). We observed a higher rate of LAM avulsion in the KFD group (KFD 49.5% vs MVD 32.5%; P = 0.001). When the results were evaluated according to fetal head position and station, we observed no differences in LAM avulsion. The crude odds ratio (OR) for the difference in avulsion between women in the KFD and MVD groups was 2.03 (95% CI, 1.36-3.03). However, when adjusted for duration of second stage of labor, fetal head circumference and fetal head station, the OR was no longer statistically significant (OR, 2.14 (95% CI, 0.95-4.85); P = 0.068). CONCLUSION When potential confounding factors are taken into account, the rate of LAM avulsion does not differ between women according to whether they have undergone KFD or MVD.

Abstract
OBJECTIVE The aim of this study was to determine whether remission and low disease activity state protect systemic lupus erythematosus patients from being hospitalized. MATERIALS AND METHODS Patients from the Almenara Lupus Cohort were included. Visits were performed every 6 months. Variables were measured at each visit. Hospitalizations were evaluated in the interval between two visits. Remission was defined as: a SLEDAI-2 K of 0, prednisone ≤5 mg/day and immunosuppressants on maintenance dose; low disease activity state as: a SLEDAI-2 K of ≤4, prednisone ≤7.5 mg/day and immunosuppressants on maintenance dose. Univariable and multivariable interval-censored survival regression models were used. In multivariable analysis, possible confounders were gender, age at diagnosis, socioeconomic status, educational level, disease duration, antimalarial use, the Systemic Lupus International Collaborating Clinics/American College of Rheumatology damage index (SDI) and Charlson comorbidity index. Confounders were determined in the same visit as disease activity state. RESULTS Of the 308 patients, 92.5% of them (n = 285) were women, had a mean age at diagnosis of 34.8 (13.4) years and a disease duration of 7.7 (6.5) years. At baseline the mean SDI was 1.13 (1.34). A total of 163 of the patients were hospitalized. In the multivariable analysis remission (hazard ratio 0.445 (0.274-0.725), P = 0.001) and low disease activity state (relative risk 0.504 (0.336-0.757), P = 0.001) at baseline were found to decrease the risk of hospitalization in systemic lupus erythematosus patients. A total of 158 hospitalizations presented a discernible cause. Disease activity was the most common cause of hospitalization, with 84 admissions (53.16%), the majority, 38, was due to active kidney disease (45.23%). CONCLUSION Remission and low disease activity state decreased the risk of hospitalizations in these systemic lupus erythematosus patients. Disease activity, particularly renal, was the most frequent cause of hospitalization.

Abstract
Streptococcus pneumoniae is able to activate coagulation and induce platelet aggregation, both of which are typical responses to systemic inflammation. The interactions between inflammation and coagulation and between soluble adhesion molecules and endothelial cells are important in the pathogenesis of an unbalanced haemostatic system. Therefore, an exaggerated and/or insufficiently controlled haemostatic activity may appreciably contribute to the severity of the disease. The aim of the present study was to evaluate the effect of the oral administration of Lactobacillus casei CRL 431 on platelet and endothelial activation mechanisms in a respiratory pneumococcal infection model in mice. S. pneumoniae induced an increase in platelet counts and enhanced the expression of P-selectin in control group, with higher endothelial activation in lung shown by the increase in von Willebrand factor (vWF) and vascular cell adhesion molecule 1 (VCAM-1) expression. Also, infection induced a decrease in CXCR-4 leukocytes, increased expression in annexinV and cell death at the pulmonary level and decreased antithrombin levels in bronchoalveolar lavage. In contrast, L. casei mice restored platelet counts, favoured faster P-selectin expression, lower vWF levels and VCAM-1 expression than control group. Also, L. casei induced higher levels of annexinV expression and lower cell death in the lung. Moreover, it was able to modulate antithrombin levels within the normal range, which would indicate lower coagulation activation and a protective effect locally exerted by L. casei. In this work, the ability of L. casei to favourably modulate platelet and endothelial functionality during a pulmonary infection with S. pneumoniae was demonstrated. Our findings offer a promising perspective for the use of this probiotic strain in the prevention of thrombotic complications associated with pneumococcal pneumonia, especially in at-risk patients. In addition, the use of L. casei would provide novel alternatives for the prevention and treatment of thrombosis associated with various diseases.

Abstract
BACKGROUND AND PURPOSE Cochlear malformations may be be subtle on imaging studies. The purpose of this study was to evaluate the angle and depth of the lateral second interscalar ridge or notch in ears without sensorineural hearing loss (normal ears) and compare them with ears that have a documented incomplete type II partition malformation. MATERIALS AND METHODS The second interscalar ridge notch angle and depth were measured on MR imaging in normal ears by a single experienced neuroradiologist. The images of normal and incomplete partition II malformation ears were then randomly mixed for 2 novice evaluators to measure both the second interscalar ridge notch angle and depth in a blinded manner. For the mixed group, interobserver agreement was calculated, normal and abnormal ear measurements were compared, and receiver operating characteristic curves were generated. RESULTS The 94 normal ears had a mean second interscalar ridge angle of 80.86° ± 11.4° and depth of 0.54 ± 0.14 mm with the 98th percentile for an angle of 101° and a depth of 0.3 mm. In the mixed group, agreement between the 2 readers was excellent, with significant differences for angle and depth found between normal and incomplete partition type II ears for angle and depth on average (P < .001). Receiver operating characteristic cutoffs for delineating normal from abnormal ears were similar for both readers (depth, 0.31/0.34 mm; angle, 114°/104°). CONCLUSIONS A measured angle of >114° and a depth of the second interscalar ridge notch of ≤0.31 mm suggest the diagnosis of incomplete partition type II malformation and scala communis. These measurements can be accurately made by novice readers.

Abstract
Background Parkinson’s disease progressively limits patients at different levels and as a result family members play a key role in their care. However, studies show lack of an integrative approach in Primary Care to respond to the difficulties and psychosocial changes experienced by them. The aim of this study is to evaluate the effects of a multidisciplinary psychoeducational intervention focusing on improving coping skills, the psychosocial adjustment to Parkinson’s disease and the quality of life in patients and family carers in a Primary Care setting. Methods This quasi-experimental study with control group and mixed methods was designed to evaluate a multidisciplinary psychoeducational intervention. Based on the study power calculations, 100 people with Parkinson’s disease and 100 family carers will be recruited and assigned to two groups. The intervention group will receive the ReNACE psychoeducational intervention. The control group will be given a general educational programme. The study will be carried out in six community-based health centres. The results obtained from the two groups will be collected for evaluation at three time points: at baseline, immediately after the intervention and at 6 months post-intervention. The results will be measured with these instruments: the Quality of Life Scale PDQ-39 for patients and the Scale of Quality of Life of Care-givers SQLC for family carers, and for all participants the Psychosocial Adjustment to Illness scale and the Brief COPE Inventory. Focus groups will be organised with some patients and family carers who will have received the ReNACE psychoeducational intervention and also with the healthcare professionals involved in its development. Discussion An important gap exists in the knowledge and application of interventions with a psychosocial approach for people with PD and family carers as a whole. This study will promote this comprehensive approach in Primary Care, which will clearly contribute in the existing knowledge and could reduce the burden of PD for patients and family carers, and also in other long-term conditions. Trial registration NCT03129425 (ClinicalTrials.gov). Retrospectively registered on April 26, 2017.

Abstract
Abstract
We compare the effects of breast cancer education and empowerment approaches on non-adherent Latinas' breast health behaviors and dissemination of health information. Methods: The setting for this ongoing, quasi-experimental trial is two Latino, lower income communities in Chicago. Women were recruited via two community-based organizations and snowball sampling. Eligibility criteria were: 1) age of 52–74; 2) lack of screening within past 2 years; 3) no previous breast cancer diagnosis; and, 4) no health volunteerism experience. Women were assigned to a three week group intervention (3 2 hour sessions). The education intervention is administered in East Side/South Chicago and the empowerment intervention is administered in Pilsen/Little Village to avoid contamination effects. The education intervention has 3 sessions focused on early detection and prevention (diet, physical activity). The empowerment intervention has 3 sessions focused on early detection, sharing information with family/friends, and health volunteerism. Navigation is provided if women wish to obtain mammograms. Three questionnaires are given at baseline, post-intervention, and a 6 month follow-up. Results: Among our 68 participants (34 education; 34 empowerment), 87% were born in Mexico; 59% had <9th grade education; 52% had a median household income of <$10K; and, 51% were uninsured. The average age was 61.21 (SD = 6.20). Relative to education participants, more empowerment participants have scheduled mammograms (94% vs. 74%; P = 0.05) and obtained mammograms (77% vs. 38%, P = 0.001). Empowerment participant also spoke to more individuals about breast health relative to education participants (M = 6.24, SD = 5.30 vs. M = 3.00, SD = 3.04, P = 0.003). A greater proportion of engagement participants also spoke about specific types of breast cancer screening (58% vs. 38%, P = 0.01) and discussed breast cancer across multiple settings (58% vs. 24%, P = 0.003). Discussion: The empowerment approach may be particularly effective in changing non-adherent Latinas' screening behaviors and promoting them to become agents of change in their communities. Limitations concern generalizability due a non-probability based sample, and limited ability for causal inferences due to a lack of randomization.

Abstract
Importance of bifidobacteria as part of the infant intestinal microbiota has been highlighted. Their acquisition is influenced by the mode of birth and the feed regime afterwards, with a special role of the maternal microbiota. The presence of the same shared bifidobacterial strains between breast milk and infant faeces in 14 mother-infant pairs was assessed by means of pulsed-field gel electrophoresis (PFGE) genotyping. Four shared strains of Bifidobacterium breve (2), Bifidobacterium longum subsp. infantis and B. longum subsp. longum were found in breast milk-infant faeces pairs. Two years later, a second survey yielded four shared strains of the species Bifidobacterium adolescentis, Bifidobacterium bifidum, B. longum subsp. longum and Bifidobacterium pseudocatenulatum. Moreover, a B. bifidum strain was found to be shared by the infant faeces of the first study and the mother faeces tested two years later, pointing out a long term persistence. Some of the selected bifidobacterial strains showed probiotic potential due to their survival to gastrointestinal conditions and their ability to form biofilms.

Abstract
Light and temperature are major drivers in the ecology and biogeography of symbiotic dinoflagellates living in corals and other cnidarians. We examined variations in physiology among 11 strains comprising five species of clade A Symbiodinium We grew cultures at 26°C (control) and 32°C (high temperature) over a duration of 18 days while measuring growth and photochemical efficiency (Fv /Fm ). Responses to thermal stress ranged from susceptible to tolerant across species and strains. Most strains exhibited a decrease in cell densities and Fv /Fm when grown at 32°C. Tolerance to high temperature (T32) was calculated for all strains, ranging from 0 (unable to survive at high temperature) to 1 (able survive at high temperature). There was substantial variation in thermotolerance across species and among strains. One strain had a T32 close to 1, indicating that growth was not reduced at 32°C for only this one strain. To evaluate the combined effect of temperature and light on physiological stress, we selected three strains with different levels of thermotolerance (tolerant, intermediate and susceptible) and grew them under five different light intensities (65, 80, 100, 240 and 443 µmol quanta m-2 s-1) at 26 and 32°C. High irradiance exacerbated the effect of high temperature, particularly in strains from thermally sensitive species. This work further supports the recognition that broad physiological differences exist not only among species within Symbiodinium clades, but also among strains within species demonstrating that thermotolerance varies widely between species and among strains within species.

Abstract
The most frequent sequelae following a translabyrinthine approach for vestibular schwannoma resection is complete hearing loss on the affected side. Such patients could benefit from a cochlear implant, provided that two essential requisites are met before surgery: a preserved cochlear nerve and a patent cochlea to accommodate the electrode array. The goal of our study is to determine the prevalence and extent of cochlear ossification following a translabyrinthine approach. Postoperative MRI of 41 patients were retrospectively reviewed. Patients were classified according to the degree of cochlear obliteration into three groups (patent cochlea, partially obliterated cochlea and totally obliterated cochlea). The interval between surgery and the first MRI was studied as well as its relationship with the rate of cochlear ossification. At first postoperative MRI (mean interval of 20 months), 78% of patients showed some degree of cochlear ossification. Differences were found in the time interval between surgery and first MRI for each group, showing a smaller interval of time the patent cochlea group (p > 0.05). When MRI was performed before the first year after surgery, a larger rate of patent cochlea was found (p > 0.05). The present study suggests that cochlear ossification is a time-depending process, whose grounds are still to be defined.

Abstract
AIMS The aim of this study was the coproduction in a single strain of the Gram-negative bacteriocin colicin V with other bacteriocins from lactic acid bacteria (LAB). METHODS AND RESULTS Colicin V was expressed in Lactococcus and Enterococcus strains by replacing the colicin V leader peptide by the leader peptide and promoter of d-alanyl-d-alanine carboxypeptidase from Lactobacillus reuteri CECT925 in pNZ8048 (pNZ:LR-colV). The antimicrobial activity of colicin V against the indicator organism Escherichia coli DH5α in transformed strains was checked by agar diffusion assay and SDS-PAGE analysis. CONCLUSIONS Lactococcus and Enterococcus transformed with pNZ:LR-colV were able to coproduce colicin V at high levels together with other LAB bacteriocins such as nisin A, nisin Z, lacticin 481 or enterocins A and B, obtaining broad-spectrum activity strains with large potential applications. SIGNIFICANCE AND IMPACT OF THE STUDY The construction showed in this work could be used for the heterologous expression of other bacteriocins active against Gram-negative bacteria or wide-spectrum bacteriocins from LAB.

Abstract
Objectives The objective of this study was to determine whether prolactin levels are associated with a pro-inflammatory body mass distribution in women with systemic lupus erythematosus (SLE). Methods This cross-sectional study was conducted in consecutive female SLE patients seen in our rheumatology department from January 2012 to July 2015. Prolactin was measured in ng/ml. Body mass distribution was measured by dual energy x-ray absorptiometry and it was divided into subtotal (whole body excluding the head), subtotal bone mineral content, lean mass index (appendicular lean mass/height2), subtotal trunk and leg fat percentages and trunk-to-leg fat ratio. The association between prolactin levels and body mass distribution components was evaluated by univariable and multivariable linear regression models adjusting for possible confounders. Results One hundred and eighty-five patients were evaluated; their mean (SD) age at diagnosis was 34.8 (13.8) years; nearly all patients were Mestizo. Patients included in this study were comparable to the rest of the cohort in terms of age, disease duration, SLEDAI, SDI and body mass index. Disease duration was 7.3 (6.6) years. The SLEDAI was 5.2 (4.3) and the SDI 0.9 (1.3). Prolactin levels were 18.9 (16.7) ng/ml. In univariable analyses, prolactin was negatively associated with bone mineral density, bone mineral content, leg fat percentage and lean mass index, and positively associated with trunk-to-leg fat ratio. In the multivariable analyses, prolactin was negatively associated with bone mineral content and positively associated with trunk-to-leg fat ratio. Conclusions Higher prolactin levels are associated with a pro-inflammatory body mass distribution in SLE patients.

Abstract
Phytoestrogens are polyphenols similar to human estrogens found in plants or derived from plant precursors. Phytoestrogens are found in high concentration in soya, flaxseed and other seeds, fruits, vegetables, cereals, tea, chocolate, etc. They comprise several classes of chemical compounds (stilbenes, coumestans, isoflavones, ellagitannins, and lignans) which are structurally similar to endogenous estrogens but which can have both estrogenic and antiestrogenic effects. Although epidemiological and experimental evidence indicates that intake of phytoestrogens in foods may be protective against certain chronic diseases, discrepancies have been observed between in vivo and in vitro experiments. The microbial transformations have not been reported so far in stilbenes and coumestans. However, isoflavones, ellagitanins, and lignans are metabolized by intestinal bacteria to produce equol, urolithins, and enterolignans, respectively. Equol, urolithin, and enterolignans are more bioavailable, and have more estrogenic/antiestrogenic and antioxidant activity than their precursors. Moreover, equol, urolithins and enterolignans have anti-inflammatory effects and induce antiproliferative and apoptosis-inducing activities. The transformation of isoflavones, ellagitanins, and lignans by intestinal microbiota is essential to be protective against certain chronic diseases, as cancer, cardiovascular disease, osteoporosis, and menopausal symptoms. Bioavailability, bioactivity, and health effects of dietary phytoestrogens are strongly determined by the intestinal bacteria of each individual.

Abstract
OBJECTIVE To determine whether circulating CD4+CD28null and extra-thymic CD4+CD8+ double positive (DP) T cells are independently associated with damage accrual in systemic lupus erythematosus (SLE) patients. METHODS This cross-sectional study was conducted between September 2013 and April 2014 in consecutive SLE patients from our Rheumatology Department. CD4+CD28null and CD4+CD8+ DP T-cell frequencies were analyzed by flow-cytometry. The association of damage (SLICC/ACR Damage Index, SDI) and CD4+CD28null and CD4+CD8+ DP T cells was examined by univariable and multivariable Poisson regression models, adjusting for possible confounders. All analyses were performed using SPSS 21.0. RESULTS Patients' (n = 133) mean (SD) age at diagnosis was 35.5 (16.8) years, 124 (93.2%) were female; all were mestizo (mixed Caucasian and Amerindian ancestry). Disease duration was 7.4 (6.8) years. The SLE Disease Activity Index was 5.5 (4.2), and the SDI 0.9 (1.2). The percentages of CD4+CD28null and CD4+CD8+ DP T cells were 17.1 (14.4) and 0.4 (1.4), respectively. The percentage of CD4+CD28null and CD4+CD8+ DP T cells were positively associated with a higher SDI in both univariable (rate ratio (RR) 1.02, 95% confidence interval (CI): 1.01-1.03 and 1.17, 95% CI: 1.07-1.27, respectively; p < 0.001 for both) and multivariable analyses RR 1.02, 95% CI: 1.01-1.03, p = 0.001 for CD4+CD28null T cells and 1.28, 95% CI: 1.13-1.44, p < 0.001 for CD4+CD8+ DP T cells). Only the renal domain remained associated with CD4+CD28null in multivariable analyses (RR 1.023 (1.002-1.045); p = 0.034). CONCLUSIONS In SLE patients, CD4+CD28null and CD4+CD8+ DP T cells are independently associated with disease damage. Longitudinal studies are warranted to determine the predictive value of these associations.

Abstract
OBJECTIVE To analyze the long term outcomes after surgery in tympanomastoid paragangliomas. STUDY DESIGN Retrospective study. METHODS The charts of 145 patients with tympanomastoid paragangliomas managed between 1988 and 2013 were reviewed. The clinical features, audiological data, pre- and postoperative notes were noted. The tumors were staged according to the modified Fish and Mattox classification. The surgical approaches for all patients were formulated according to the surgical algorithm developed at our center. RESULTS 34 (23.5%), 46 (31.7%), 22 (15.2%), 18 (12.4%) and 25 (17.2%) patients were diagnosed to have TMP class A1, A2, B1, B2 and B3 tumors respectively. Gross tumor resection was achieved in 141 (97.2%) patients. The facial nerve was uncovered in four patients and infiltrated in three. The cochlea was found eroded in seven cases. The mean follow-up was 48.4 months. Recurrence was seen in one patient (0.7%). In the cases where the facial nerve was preserved (n=143), the nerve function was graded as HB grade 1 in 138 patients (97%). Postoperatively, the mean AC showed an improvement in all categories except in class B2 and B3, which corresponds to the classes that include patients who underwent subtotal petrosectomy. CONCLUSION We report the long term surgical outcomes in tympanomastoid paragangliomas in the largest series published till date. It is possible to completely eradicate all types of tympanomastoid paragangliomas with minimum sequelae by choosing the correct surgical approach to achieve adequate exposure for individual tumor classes as described in our classification and algorithm. LEVEL OF EVIDENCE IIb.
