Minimally conscious state plus versus minus: Likelihood of emergence and long-term functional independence.

OBJECTIVE: Severe brain injuries can result in disorders of consciousness, such as the Minimally Conscious State (MCS), where individuals display intermittent yet discernible signs of conscious awareness. The varied levels of responsiveness and awareness observed in this state have spurred the progressive delineation of two subgroups within MCS, termed "plus" (MCS+) and "minus" (MCS-). However, the clinical validity of these classifications remains uncertain. This study aimed to investigate and compare the likelihood of emergence from MCS, as well as the functional independence after emergence, in individuals categorized as in MCS+ and MCS-. METHODS: Demographic and behavioral data of 80 participants, admitted as either in MCS+ (n = 30) or MCS- (n = 50) to a long-term neurorehabilitation unit, were retrospectively analyzed. The neurobehavioral condition of each participant was evaluated weekly until discharge, demise, or emergence from MCS. The functional independence of those participants who emerged from MCS was assessed 6 months after emergence. RESULTS: While only about half of the individuals classified as in MCS- (n = 24) emerged from the MCS, all those admitted as in MCS+ did, and in a shorter postinjury period. Despite these differences, all individuals who emerged from the MCS demonstrated similar high disability and low functional independence 6 months after emergence, regardless of their state at admission. INTERPRETATION: Individuals classified as MCS+ exhibited a higher likelihood of emergence and a shorter time to emergence compared to those in MCS-. However, the level of functional independence 6 months after emergence was found to be unrelated to the initial state at admission.

Reliability and validity of the Spanish adaptation of the Functional Independence Measure + Functional Assessment Measure.

BACKGROUND: The Functional Independence Measure + Functional Assessment Measure (FIM+FAM) Scale is one of the most widely used instruments to measure functional independence post-stroke, and features many cultural adaptations to various languages. AIM: The aim of this study was to determine the psychometric properties of a Spanish cross-cultural adaptation of the FIM+FAM for use in the stroke population. DESIGN: Observational study. SETTING: Outpatient long-term service of a neurorehabilitation unit. POPULATION: One hundred and twenty-two individuals with stroke. METHODS: The functional independence of the participants was assessed with the adapted version of the FIM+FAM. Additionally, the functional, motor and cognitive condition of the participants was assessed with a battery of standardized clinical instruments. Finally, a group of 31 participants out of the total were evaluated a second time with the FIM+FAM by a different evaluator than the one who performed the first evaluation. Internal consistency, inter-rater reliability and convergent validity with other clinical instruments of the adapted version of the FIM+FAM were determined. RESULTS: The internal consistency of the adapted version of the FIM+FAM was excellent, as evidenced by Cronbach's α values that exceeded 0.973. The inter-rater reliability was likewise excellent, with correlations above 0.990 in all domains and subscales. Additionally, the convergent validity of the scale adaptation with clinical instruments was variable, with values ranging from 0.264 to 0.983, but consistent with the construct assessed in the different instruments examined. CONCLUSIONS: The internal consistency, inter-rater reliability and convergent validity of the Spanish-adapted version of the FIM+FAM Scale showed excellent reliability and validity of the adaptation, which supports its use to assess functional independence after stroke. CLINICAL REHABILITATION IMPACT: Availability of a valid adaptation for the evaluation of functional independence after stroke in Spanish population.

Conventional follicular-phase ovarian stimulation vs. luteal-phase stimulation in suboptimal responders: a randomized controlled trial.

Objective: To compare the oocyte yield between follicular-phase stimulation (FPS) and luteal-phase stimulation (LPS) in suboptimal responders. Design: Prospective, randomized, crossover clinical trial. Patients: Forty-one patients with infertility according to the POSEIDON (Patient-Oriented Strategies Encompassing IndividualizeD Oocyte Number) criteria (1b/2b). Interventions: Crossover study on 2 assigned ovarian stimulations that started randomly in the follicular or luteal phase. The in vitro fertilization cycles were not consecutive but separated in time (45 days to 6 months). The random crossover design ensured that all subjects received the first treatment by chance. Main Outcome Measures: The primary objective was the number of cumulus-oocyte complexes retrieved in each cycle. Secondary objectives were number of metaphase II and fertilized oocytes, additional doses of recombinant follicle-stimulating hormone, and the duration of ovarian stimulation (days). Results: The mean number of cumulus-oocyte complexes retrieved was similar between the FPS and LPS groups (7.5 ± 4.6 vs. 7.0 ± 4.1; 95% confidence interval [CI] for the mean, 5.8-8.7 vs. 5.6-8.3, respectively; the difference between means, -0.5; 95% CI, -1.8 to +1.5). Similarly, the mean number of metaphase II oocytes retrieved was not different between the FPS and LPS groups (5.4 ± 3.6 vs. 5.2 ± 2.8; 95% CI for the mean, 4.2-6.5 vs. 4.3-6.1, respectively; the difference between means, -0.2; 95% CI, -1.2 to +1.1). Moreover, the secondary objectives were similar between FPS and LPS groups. Conclusions: In this study, the oocyte yield in LPS did not increase in suboptimal responders compared with that in FPS when the onset of LPS was separated in time from FPS.

The Effect of Twisted Uterus Caused by Endometriosis or Myomatosis on Reproductive Treatment Outcomes.

Objective: Twisted uterus is detected when the body of the uterus is rotated from the cervical canal. This anomaly may be due to different causes, such as uterine fibroids, endometriosis or the presence of both. The study has aimed to compare the effect of the twisted uterus cause in terms of reproductive treatment outcomes. Materials and methods: It consisted of a retrospective study of twisted uterus cases with repeated implantation failure (more than three embryo transfers or four blastocysts transferred unsuccessfully) in our ultrasound department. The twisted uterus was defined when the vaginal probe needed to be rotated to assess the endometrial line thoroughly or when the coronal view was seen by 2D scan. From 2017 to 2020, 879 gynecological ultrasounds were performed. For statistical analysis, we carried out a logistical regression analysis adjusted by confounding factors. Results: From 145 patients included only 92 patients underwent reproductive treatments. With the known cause of uterine torsion. 56 patients with endometriosis, 18 with uterine myoma and the remaining 18 suffered from both. After assisted reproductive treatment, the endometriosis group showed the highest clinical pregnancy rate (53.57%) compared to myoma (22.22%) and endometriosis and myoma (38.89%) groups. Conclusion: Uterine myoma capable of causing uterine torsion may affect embryo implantation more than endometriosis. Prospective randomized studies with a larger number of patients would be needed to confirm these findings.

Impact of the Vaginal and Endometrial Microbiome Pattern on Assisted Reproduction Outcomes.

Uterine microbiota may be involved in reproductive health and disease. This study aims to describe and compare the vaginal and endometrial microbiome patterns between women who became pregnant and women who did not after in vitro fertilization. We also compared the vaginal and endometrial microbiome patterns between women with and without a history of repeated implantation failures (RIF). This pilot prospective cohort study included 48 women presenting to the fertility clinic for IVF from May 2017 to May 2019. Women who achieved clinical pregnancy presented a greater relative abundance of Lactobacillus spp. in their vaginal samples than those who did not (97.69% versus 94.63%; p = 0.027. The alpha and beta diversity of vaginal and endometrial samples were not statistically different between pregnant and non-pregnant women. The Faith alpha diversity index in vaginal samples was lower in women with RIF than those without RIF (p = 0.027). The alpha diversity of the endometrial microbiome was significantly higher in women without RIF (p = 0.021). There were no significant differences in the vaginal and endometrial microbiomes between pregnant and non-pregnant women. The relative abundance of the genera in women with RIF was different from those without RIF. Statistically significant differences in the endometrial microbiome were found between women with and without RIF.

4D ultrasound as a method to assess uterine peristalsis.

OBJECTIVE: To study uterine peristalsis using step-by-step 4-dimensional (4D) ultrasound assessment video, explore its relationship with progesterone levels in a select in vitro fertilization population, and assess the reproducibility of the technique. DESIGN: Four-dimensional uterine ultrasound and a retrospective analysis of outcomes in relation with progesterone levels. The videos were also analyzed by a senior doctor, junior doctor, and a nurse for their reproducibility. SETTING: Instituto Bernabeu of Alicante is a private clinic. PATIENT(S): The study included 197 consecutive patients undergoing in vitro fertilization (from 2018 to 2019) with a history of recurrent implantation failure (defined as unsuccessful implantation of a total number of ≥3 blastocysts originated from oocyte donation cycles). Because it is known that most failures are attributed to the quality of the embryo, we deemed it important to explore the potential uterine factors explaining the failures in oocyte donation cycles, the use of which decreases the probability of embryo-related factors influencing it. INTERVENTION(S): The participants were evaluated for uterine contractions and serum progesterone levels (10-30 minutes before the embryo transfer procedure). Uterine contractility (UC) was assessed by recording a 6-minute-long video using a 4D mode (Voluson E10; General Electric, Boston, MA), which was performed by a single operator (B.M.). MAIN OUTCOMES MEASURE(S): The contractions were seen like waves going through the endometrial cavity. They were counted on a ×15 accelerated recording video. To define high-frequency UC, we separated uterine peristalsis (contractions per minute [cpm]) into quartiles. The highest quartile defined the hypercontractility group (>1.51 cpm; n = 41), considering the remaining quartiles as the normal contractility group (≤1.51 cpm; n = 156). The Mann-Whitney U test was performed. The intraclass correlation coefficient was used to validate variability. P <.05 was considered significant. SPSS version 21.0 was used for the statistical analysis. The institutional review board's approval was obtained. RESULT(S): Overall, an average of 1.1 cpm was found in the study population. There were no differences between the groups (hypercontractility vs. normal contractility) in terms of patient age and the presence of any uterine factor (adenomyosis, myomas, adhesions, or polyps). An inverse association was observed between UC and progesterone levels. Low progesterone levels (15.9 vs. 19.5 ng/mL; P = .027) were observed in the HUP and NUP group, respectively. The intraclass correlation coefficient to evaluate the interobserver variability was 0.75 (0.63-0.85; P = .000). CONCLUSION(S): Four-dimensional ultrasound assessment provides a dynamic view of uterine contractions, including their directionality and frequency. Even though recurrent implantation failure is yet a title of obscure definition and probably associated with multiple factors, a subgroup of patients with elevated UC associated with "low" progesterone levels may have a potential effect on their outcomes. Four-dimensional scan evaluation of UC constitutes a promising diagnostic tool in clinical practice; however, larger studies confirming our initial results are still pending.

When, How, and to What Extent Are Individuals with Unresponsive Wakefulness Syndrome Able to Progress? Neurobehavioral Progress.

Accurate estimation of the neurobehavioral progress of patients with unresponsive wakefulness syndrome (UWS) is essential to anticipate their most likely clinical course and guide clinical decision making. Although different studies have described this progress and possible predictors of neurobehavioral improvement in these patients, they have methodological limitations that could restrict the validity and generalization of the results. This study investigates the neurobehavioral progress of 100 patients with UWS consecutively admitted to a neurorehabilitation center using systematic weekly assessments based on standardized measures, and the prognostic factors of changes in their neurobehavioral condition. Our results showed that, during the analyzed period, 34% of the patients were able to progress from UWS to minimally conscious state (MCS), 12% of the total sample (near one third from those who progressed to MCS) were able to emerge from MCS, and 10% of the patients died. Transition to MCS was mostly denoted by visual signs, which appeared either alone or in combination with motor signs, and was predicted by etiology and the score on the Coma Recovery Scale-Revised at admission with an accuracy of 75%. Emergence from MCS was denoted in the same proportion by functional communication and object use. Predictive models of emergence from MCS and mortality were not valid and the identified predictors could not be accounted for.

When, How, and to What Extent Are Individuals with Unresponsive Wakefulness Syndrome Able to Progress? Functional Independence.

Accurate estimation of the functional independence of patients with unresponsive wakefulness syndrome (UWS) is essential to adjust family and clinical expectations and plan long-term necessary resources. Although different studies have described the clinical course of these patients, they have methodological limitations that could restrict generalization of the results. This study investigates the neurobehavioral progress of 100 patients with UWS consecutively admitted to a neurorehabilitation center using systematic weekly assessments based on standardized measures, and the functional independence staging of those patients who emerged from a minimally conscious state (MCS) during the first year post-emergence. Our results showed that one year after emergence, most patients were severely dependent, although some of them showed extreme or moderate severity. Clinically meaningful functional improvement was less likely to occur in cognitively-demanding activities, such as activities of daily living and executive function. Consequently, the use of specific and staging functional independence measures, with domain-specific evaluations, are recommended to detect the functional changes that might be expected in these patients. The information provided by these instruments, together with that obtained from repeated assessments of the preserved consciousness with standardized instruments, could help clinicians to adjust expectations and plan necessary resources for this population.

Luteal phase stimulation versus follicular phase stimulation in poor ovarian responders: results of a randomized controlled trial.

BACKGROUND: In young women with poor ovarian response, luteal-phase ovarian stimulation (LPOS) is a potential method for collecting competent oocytes. The aim of this study was to assess the efficacy of LPOS compared with follicular phase ovarian stimulation (FPOS) in young women with poor ovarian response (POR). METHODS: This single-center, prospective, randomized pilot study compared LPOS and FPOS in women with POR fulfilling Bologna criteria who underwent in vitro fertilization at the Instituto Bernabeu. The primary outcome was the number of metaphase II (MII) oocytes obtained by follicular puncture. RESULTS: Sixty women were included in the study, with 27 women completing LPOS and 30 undergoing FPOS. There was no statistically significant difference in the number of MII oocytes obtained between the LPOS group and the FPOS group (2.1 ± 2.0 vs. 2.6 ± 2.2, p = 0.31). Length of stimulation was also similar in both groups (8.35 ± 2.8 vs. 8.15 ± 4.1 days, p = 0.69). Similarly, there was no significant difference in the follicle-stimulating hormone total dose, number of cumulus-oocyte complexes, survival rate, fertilization rate, or cancellation rate between groups. A significantly higher Ovarian Sensitivity Index was observed in the LPOS group versus the FPOS group (0.96 vs. 0.57, p = 0.037). CONCLUSION: LPOS was comparable with FPOS in terms of efficacy and may improve ovarian responsiveness in young women with POR. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT02625532; EudraCT identifier: 2015-003856-31.

Effect of the vaginal microbiome on the pregnancy rate in women receiving assisted reproductive treatment.

PURPOSE: To investigate if the vaginal microbiome influences the IVF outcome. METHODS: Thirty-one patients undergoing assisted reproductive treatment (ART) with own or donated gametes and with cryotransfer of a single euploid blastocyst were recruited for this cohort study. Two vaginal samples were taken during the embryo transfer procedure, just before transferring the embryo. The V3 V4 region of 16S rRNA was used to analyze the vaginal microbiome, and the bioinformatic analysis was performed using QIIME2, Bioconductor Phyloseq, and MicrobiomeAnalyst packages. Alpha diversity was compared between groups according to the result of the pregnancy test. RESULTS: Fourteen (45.2%) patients did not and seventeen (54.8 %) did achieve pregnancy under ART. A greater index of alpha diversity was found in patients who did not achieve pregnancy comparing to those who did, although this difference was not significant (p = 0.088). In the analysis of beta diversity, no statistically significant differences were observed between groups established as per the pregnancy status. Samples from women who achieved pregnancy showed a greater presence of Lactobacillus spp. The cluster analysis identified two main clusters: the first encompassed the genera Lactobacillus, Gardnerella, Clostridium, Staphylococcus, and Dialister, and the second included all other genera. Women who achieved pregnancy were mainly detected microorganisms from the first cluster. CONCLUSIONS: The vaginal microbiome can influence the results of ART. The profiles dominated by Lactobacillus were associated with the achievement of pregnancy, and there was a relationship between the stability of the vaginal microbiome and the achievement of pregnancy.

Visual Behavior, Pupil Dilation, and Ability to Identify Emotions From Facial Expressions After Stroke.

Social cognition is the innate human ability to interpret the emotional state of others from contextual verbal and non-verbal information, and to self-regulate accordingly. Facial expressions are one of the most relevant sources of non-verbal communication, and their interpretation has been extensively investigated in the literature, using both behavioral and physiological measures, such as those derived from visual activity and visual responses. The decoding of facial expressions of emotion is performed by conscious and unconscious cognitive processes that involve a complex brain network that can be damaged after cerebrovascular accidents. A diminished ability to identify facial expressions of emotion has been reported after stroke, which has traditionally been attributed to impaired emotional processing. While this can be true, an alteration in visual behavior after brain injury could also negatively contribute to this ability. This study investigated the accuracy, distribution of responses, visual behavior, and pupil dilation of individuals with stroke while identifying emotional facial expressions. Our results corroborated impaired performance after stroke and exhibited decreased attention to the eyes, evidenced by a diminished time and number of fixations made in this area in comparison to healthy subjects and comparable pupil dilation. The differences in visual behavior reached statistical significance in some emotions when comparing individuals with stroke with impaired performance with healthy subjects, but not when individuals post-stroke with comparable performance were considered. The performance dependence of visual behavior, although not determinant, might indicate that altered visual behavior could be a negatively contributing factor for emotion recognition from facial expressions.

Progression of posturographic findings after acquired brain injury.

OBJECTIVE: To study the characteristics of balance performance in a sample of patients with increasing postural instability after acquired brain injury (ABI) and to establish the clinical utility of a new computerized posturographic system (NedSVE/IBV). METHODS: This study included 108 patients with ABI divided into five groups from minimal to severe postural impairment. All patients were assessed with the NedSVE/IBV system and with traditional balance measures. Posturographic analyses included the modified clinical test of sensory interaction on balance, the limits of stability and the weight-shifting test. Sensitivity to detect changes and reproducibility were evaluated in 63 patients who were followed-up for 6 months and in 20 patients who were evaluated on two separate occasions during the same week, respectively. RESULTS: The patients showed reduced stability limits, abnormal postural responses and an increased reliance on visual input with differences in intensity directly related to their degree of balance impairment. Posturographic study showed excellent convergent validity, reproducibility and sensitivity to detect changes. CONCLUSION: The data suggests that, regardless of the intensity of postural instability, there is a common mechanism of sensory processing to maintain balance after ABI. The NedSVE-IBV system is a valid tool to quantify balance after ABI.

Uterine arteriovenous malformation.

Uterine arteriovenous malformation (AVM) is a little known condition of which, to date, very few cases have been described. It has a very diverse symptomatology, even though in most cases, it is diagnosed during a severe and acute haemorrhagic event. Its treatment can vary from expectant management to hysterectomy; however, current evidence suggests that the embolisation of uterine arteries is the most effective approach, especially if fertility is to be preserved. We present a case report classified as AVM, with additional images that show the appearance of this pathology in a short span of time. This case has a number of peculiarities: unusual persistence of human chorionic gonadotropin hormone (ß-HCG), asymptomatic patient, quick establishment of the lesion and its duration with unchanging characteristics and finally its spontaneous resolution without further consequences. This entity shows an aetiopathogenesis, that is, not well established or described. We discuss its physiopathology and aetiopathogenesis.

Behavioral recovery in disorders of consciousness: a prospective study with the Spanish version of the Coma Recovery Scale-Revised.

OBJECTIVE: To describe the clinical characteristics and short-term pattern of evolution of a sample of patients within 1 year after acquiring a brain injury that led to a vegetative state (VS) or a minimally conscious state (MCS). DESIGN: Cohort study. SETTING: Inpatient brain injury rehabilitation program. PARTICIPANTS: Patients with acquired brain injury (N=32; 47% traumatic, 37.5% hemorrhagic, 15.5% anoxic) who were in a VS or an MCS according to Coma Recovery Scale-Revised (CRS-R) scores. INTERVENTION: Integrative multisensory program comprising daily physical rehabilitation procedures and multimodal sensory stimulation. MAIN OUTCOME MEASURE: All patients were assessed with a Spanish version of the CRS-R at admission and then monthly for at least 6 months or until emergence from MCS. RESULTS: At the time of admission, 12 patients were diagnosed as being in a VS and 20 as being in an MCS. Eight patients were able to emerge from their MCS during follow-up. Seven of these 8 patients were diagnosed as being in an MCS at inclusion, and only 1 was diagnosed as being in a VS. Emergence from an MCS was mostly associated with improvement in both the communication and motor function scales (n=4). Lesser chronicity (P=.01) and the presence of more than visual behavioral responses at admission (P=.05) were both significant predictors of emergence from an MCS. CONCLUSIONS: The CRS-R seems appropriate for establishing an immediate prognosis in this population. A quick referral of these patients for specialized assessment and rehabilitation facilities is recommended.

Quilotórax antenatal en feto euploide con translucencia nucal aumentada en el primer trimestre / Prenatal chylothorax in a euploid fetus with increased nuchal translucency in the first trimester

Gestación en que el feto presentó una translucencia nucal aumentada en el primer trimestre; el cariotipo normal fue tras la amniocentesis. A las 33 semanas se observó un derrame pleural derecho que desplazaba elmediastino, asociado a polihidramnios. Se produjoun parto prematuro a las 33,4 semanas; se obtuvoun recién nacido que presentó distrés respiratorio yrequirió colocación de un drenaje torácico. Lapresencia de linfocitos en el líquido pleural orientóel diagnóstico hacia un quilotórax. Aunque es conocida la asociación entre translucencia nucal aumentada con cariotipo normal y resultados perinatales desfavorables, la asociación con quilotórax es infrecuente

We report a pregnancy in which the fetus showedincreased nuchal translucency in the first trimesterand normal karyotype on amniocentesis. At 33 weeks’ gestation, right fetal hydrothorax, producingmediastinal displacement and associated withpolyhydramnios, was noted. Preterm labor occurred at 33.4 weeks, with respiratory distress in the newborn, requiring thoracic drainage. The presence of lymphocytes in the drained fluid confirmed the diagnosis of chylothorax. Although the association between increased nuchal translucency with a normal karyotype and impairedperinatal outcome is well known, an associationwith chylothorax is infrequent
