RESUMEN

Adaptive memory retains information that would increase survival chances and reproductive success, resulting in the survival processing effect. Less is known about whether the reliability of the information interacts with the survival processing effect. From an adaptive point, information from reliable sources should lead to better encoding of information, particularly in a survival context. In Turkish, specific linguistic components called evidentiality markers encode whether the information presented is firsthand (direct) or not (indirect), providing insight into source reliability. In two experiments, we examined the effect of evidentiality markers on recall across survival and nonsurvival (moving) contexts, predicting that the survival processing effect would be stronger for information marked with evidentiality markers indicating direct information. Results of both experiments yielded a robust survival processing effect, as the sentences processed for their relevance to survival were better remembered than those processed for their relevance to nonsurvival events. Yet the marker type did not affect retention, regardless of being tested as a between- or within-subject factor. Specifically, the survival processing effect persisted even with evidentiality markers indicating indirect information, which suggests that the processing of survival-related information may be privileged even if potentially unreliable. We discuss these results in the context of recent studies of the interaction of language with memory.

RESUMEN

BACKGROUND: The purpose of this study was to investigate the long-term mortality rates of patients with obstructive sleep apnea (OSA) who received an overnight polysomnogram (PSG) for obtaining the diagnosis and to determine the relationship between PSG parameters and overall mortality. METHODS: Between 2007 and 2013, patients who had overnight PSG and were diagnosed with OSA were included in the study. Factors which are thought to influence mortality were assessed for 5-year and overall survival using the log rank test and Kaplan-Meier survival curves. Using multivariable Cox regression analysis, a model was constructed for factors influencing 5-year and overall survival. RESULTS: A total of 762 patients with a mean age of 52.7 (±10.8) and a dominance of men (74.7%) were studied. Gender, OSA severity subgroups, and apnea hypopnea index (AHI) were not statistically significantly associated with either 5-year or overall mortality (p<0.05 for both). Age, having a cardiovascular comorbidity, proportion of rapid eye movement (%REM), and total sleep time with an oxyhemoglobin saturation of less than 90% (T90) all showed a significant correlation with overall all-cause mortality in the model. For 5-year mortality and overall mortality, the hazard ration (HR) for T90 was 3.6 (95% CI (1.6-8.0) p=0.001) and 3 (95% CI (1.6-5.7) p=0.001), respectively. CONCLUSION: The study findings suggest that not AHI but PSG parameters of hypoxia, mainly T90, having cardiovascular comorbidity, and %REM sleep were significant risk factors for all-cause mortality in patients with OSA. The association of OSA, hypoxia, and mortality is an area that deserves further study.

RESUMEN

Information can be conveyed via multiple channels such as verbal and gestural (visual) channels during communication. Sometimes the information from different channels does not match (e.g., saying right while pointing to the left). How do addressees choose which information to act upon in such cases? In two experiments, we investigated this issue by having participants follow instructions on how to move objects on the screen. Experiment 1 examined whether people's choice of channel can be altered by feedback favoring either the verbal or the gestural channel. In Experiment 2, there was no feedback and participants were free to choose either channel. We also assessed participants' verbal and visuospatial working memory capacities. Results showed that, when faced with contradicting information, there is a natural bias at the group level toward relying on the verbal channel, although this bias can be temporarily altered by probabilistic feedback. Moreover, when labels were shorter and of higher frequency, participants relied more on the verbal channel. In the absence of feedback, the capacity of individuals' visual, but not verbal, working memory determined reliance on one channel versus the other. Collectively, these results show that information selection in communication is influenced by group-level biases, as well as the properties of items and characteristics of individuals.

RESUMEN

In educational settings, students rely on metacognitive processes to determine whether or not to exert effort. We investigated ways to minimize cognitively disengaged responses (i.e., not-fully-effortful responses) during a low-stakes mathematics assessment. Initially, we established theory-driven time thresholds for each item to detect such responses. We then administered the test to 800 eighth-graders across three conditions: (a) control (n = 271); (b) instruction (n = 267); and (c) nudge (n = 262). In the instruction condition, students were told to exert their best effort before starting the assessment. In the nudge condition, students were prompted to give their best effort following each first-attempt response that was both incorrect and not-fully-effortful. Therefore, students had multiple opportunities to adjust their level of effort. Nudges, but not effort instruction, significantly reduced students' not-fully-effortful responses. Neither the nudges nor the effort instruction significantly impacted performance. In a post-test survey, most students reported that they received nudges whenever they did not know the answer (55%). Overall, these findings suggest that while nudges reduce cognitively disengaged responses, most students appear to strategically modulate their level of effort based on self-monitoring their knowledge and response effort.

RESUMEN

Introduction: This study investigates the process data from scientific inquiry tasks of fair tests [requiring test-takers to manipulate a target variable while keeping other(s) constant] and exhaustive tests (requiring test-takers to construct all combinations of given variables) in the National Assessment of Educational Progress program. Methods: We identify significant associations between item scores and temporal features of preparation time, execution time, and mean execution time. Results: Reflecting, respectively, durations of action planning and execution, and execution efficiency, these process features quantitatively differentiate the high- and low-performing students: in the fair tests, high-performing students tended to exhibit shorter execution time than low-performing ones, but in the exhaustive tests, they showed longer execution time; and in both types of tests, high-performing students had shorter mean execution time than low-performing ones. Discussion: This study enriches process features reflecting scientific problem-solving process and competence and sheds important light on how to improve performance in large-scale, online delivered scientific inquiry tasks.

RESUMEN

Introduction: Respiratory abnormalities in obstructive sleep apnea syndrome (OSAS) are corrected with positive pressure ventilation treatments. We investigated the effect of positive airway pressure (PAP) treatment on the serum level of ischemia-modified albumin (IMA), an oxidative stress product, in OSAS patients with higher body mass index (BMI) and indication for PAP treatment. Materials and Methods: Seven consecutive female and 23 male patients with a BMI of ≥30 kg/m2 who were diagnosed as having OSAS according to ICSD3 criteria and were planned for PAP, were included. The Epworth Sleepiness Scale and STOP-Bang Questionnaire were performed. Morning arterial blood gas, hemogram, biochemistry, insulin, and IMA were measured after polysomnography and after three months of PAP. Result: There were no significant changes in lactate, CRP, and serum electrolyte levels measured before and after PAP, except for potassium. When 30 patients were compared in terms of serum IMA levels at baseline and after treatment, the mean baseline value was 0.56 absorbance units (ABSU), and the 3rd-month follow-up IMA value was 0.53 ABSU (p= 0.537). The mean serum fasting insulin level was 15.85 µIU/mL and 11.6 (p= 0.002) and the mean HOMA index was 4.4 and 3.0 (p= 0.001), respectively. Conclusions: Serum IMA levels seem not to be an appropriate marker for the evaluation of PAP treatment in OSAS patients with higher BMI. PAP is associated with a decrease in the fasting insulin level, HOMA index, and hematocrit, but not with serum electrolytes except potassium.

RESUMEN

Age-related changes are observed in the speech and gestures of neurotypical individuals. Older adults are more disfluent in speech and use fewer representational gestures (e.g., holding two hands close to each other to mean small), compared to younger adults. Using gestures, especially representational gestures, is common in difficult tasks to aid the conceptualization process and to facilitate lexical access. This study investigates how aging can affect gesture production and the co-occurrence between gesture and speech disfluency. We elicited speech and gesture samples from younger and older adults (N = 60) by using a painting description task that provided concrete and abstract contexts. Results indicated that albeit the two age groups revealed comparable overall speech disfluency and gesture rates, they differed in terms of how their disfluencies and gestures were distributed across specific categories. Moreover, the proportion of speech disfluencies that occur with a gesture was significantly higher for younger than older adults. However, the two age groups were comparable in terms of the proportion of gestures that were accompanied by a speech disfluency. These findings suggest that younger adults' language production system might be better at benefiting from other modalities, that is, gesture, to resolve temporary problems in speech planning. However, from a gesture perspective, it might be difficult to differentiate between gestures' self-oriented and communicative functions and understand their role in speech facilitation. Focusing on specific cases where speech disfluency and gestures co-occur and considering individual differences might bring insight into multimodal communication.

RESUMEN

Spasmodic dysphonia is a chronic voice disorder that is characterized by involuntary spasms of the laryngeal muscles during speech production. Botulinum toxin injection into to the laryngeal muscles is the most common and effective treatment of choice for symptoms of spasmodic dysphonia. We present a 44-year-old man with adductor spasmodic dysphonia who was diagnosed as having upper airway obstruction in a polysomnographic examination during sleep after a botulinum toxin injection.

RESUMEN

INTRODUCTION: Healthcare workers (HCWs) are at the forefront of the fight against coronavirus. The purpose of this study was to evaluate COVID-19 phobia levels of HCWs of a pandemic hospital and explore associated factors. MATERIALS AND METHODS: This was a descriptive cross-sectional study conducted on HCWs employed in a pandemic hospital. A total of 365 HCWs (95 physicians, 187 nurses and 83 assistant healthcare staffs) were included in the study. In order to evaluate COVID-19 phobia, coronavirus-19 phobia scale (C19P-S) was administrated. Chronophobia levels of frontline and nonfrontline HCWs were compared. Additionally, the effect of working in different departments, profession and associated factors on COVID-19 phobia was evaluated. RESULT: Overall, 172 HCWs completed the C19P-S and agreed to participate in the study. Mean total CP19P-S score of the HCWs included in the study was 50.1 ± 17.3. Of the study population, 59.3% participants were frontline HCWs and 40.7% were non-frontline HCWs. When frontline HCWs and nonfrontline HCWs were compared in terms of total C19P-S and subscales scores (psychological, psycho-somatic, economic, social), no statistically significant differences were found (p= 0.914, p= 0.687, p= 0.766, p= 0.347, p= 0.794, respectively).When the HCWs were divided into three groups according to departments (clinics, intensive care unit (ICU), emergency department) where they worked regardless of whether they cared for patients with COVID-19, HCWs employed in the ICUs had the highest scores regarding total C19P-S and subscales scores (p= 0.002, p= 0.001, p= 0.001, p= 0.012, p= 0.002,respectively) . Profession based comparison revealed no significant difference between the groups regarding total C19P-S score (p= 0.117). CONCLUSIONS: It is essential to make a comprehensive evaluation regarding the effects of pandemics on HCWs, not only for controlling the COVID-19 pandemic but also to protect the mental health of HCWs. Critical care professions appear to need particular attention among HCWs. The C19P-S, which assesses coronaphobia levels with psychological, psycho-somatic, economic, and social aspects could be a convenient screening tool for evaluating COVID-19 phobia levels in HWCs.

RESUMEN

OBJECTIVE: To evaluate the impact of the body position on primary central sleep apnea syndrome. METHODS: Fifty-five subjects diagnosed with central sleep apnea (CSA) through polysomnographic examinations were prospectively enrolled in the study. All patients underwent cardiologic and neurologic examinations. Primary positional central sleep apnea (PCSA) was determined when the supine Apnea-Hypopnea Index (AHI) was greater than two times the non-supine AHI. The primary PCSA and non-PCSA groups were compared in terms of demographic characteristics, sleep parameters, and treatment approaches. RESULTS: Overall, 39 subjects diagnosed with primary CSA were included in the study; 61.5% of the subjects had primary PCSA. There were no differences between the primary PCSA and non-PCSA groups regarding age, sex, body mass index (BMI), co-morbidities, and history of septoplasty. In terms of polysomnography parameters, AHI (P=.001), oxygen desaturation index (P=.002), the time spent under 88% saturation during sleep (P=.003), number of obstructive apnea (P=.011), mixed apnea (P=.009), and central apnea (P=.007) was lower in the primary PCSA group than in the non-PCSA group. Twenty-nine percent of the patients in the primary PCSA group were recommended position treatment and 71% were recommended positive airway pressure (PAP) therapy; all patients in the non-PCSA group were recommended PAP therapy. CONCLUSIONS: Our results demonstrated that the rate of primary PCSA was high (61.5%) and primary PCSA was associated with milder disease severity compared with non-PCSA. The classification of patients with primary CSA regarding positional dependency may be helpful in terms of developing clinical approaches and treatment recommendations.

RESUMEN

A series of backbone-modified N-heterocyclic carbene (NHC) complexes of iridium(i) (1d-f) have been synthesized and characterized. The electronic properties of the NHC ligands have been assessed by comparison of the IR carbonyl stretching frequencies of the in situ prepared [IrCl(CO)2(NHC)] complexes in CH2Cl2. These new complexes (1d-f), together with previously prepared 1a-c, were applied as catalysts for the α-alkylation of arylacetonitriles with an equimolar amount of primary alcohols or 2-aminobenzyl alcohol. The catalytic activities of these complexes could be controlled by modifying the N-substituents and backbone of the NHC ligands. The NHC-IrI complex 1f bearing 4-methoxybenzyl substituents on the N-atoms and 4-methoxyphenyl groups at the 4,5-positions of imidazole exhibited the highest catalytic activity in the α-alkylation of arylacetonitriles with primary alcohols. Various α-alkylated nitriles and aminoquinolines were obtained in high yields through a borrowing hydrogen pathway by using 0.1 mol% 1f and a catalytic amount of KOH (5 mol%) under an air atmosphere within significantly short reaction times.

RESUMEN

Background/aim: The NoSAS score is a new tool for the identification of high-risk patients for sleep-disordered breathing (SDB). The aim of this study was to validate the NoSAS score in a sleep clinical population in Turkey and compare its performance with the Epworth Sleepiness Scale (ESS), STOP-Bang, and Berlin questionnaires for high-risk SDB. Materials and methods: This was a retrospective study. Patients who had a full-night PSG examination between 01.03.2017 and 01.01.2018 at the sleep center of our hospital were included in the study. Demographic characteristics, anthropometrics measurements, ESS, STOP-Bang, and Berlin scores were collected from the existing data of the patients. The NoSAS score was subsequently calculated based on available data. Predictive parameters for each screening questionnaires were calculated to compare the discriminative power of those for high-risk SDB. Results: A total of 450 patients were included in the study. The sensitivity, specificity, PPV, and NPV of the NoSAS score were 81%, 51.2%, 88.2%, and 37.5% for an AHI (apnea­hypopnea index) ≥ 5 event/h and 84.5%, 38.2%, 66%, and 63.4% for an AHI ≥ 15 event/h, respectively. AUC percentages for the NoSAS score, STOP-Bang questionnaire, Berlin questionnaire, and ESS were 0.740, 0.737, 0.626, and 0.571 for an AHI ≥ 5 events/h and 0.715, 0.704, 0.574, and 0.621 for an AHI ≥ 30 events/h. The NoSAS score had a false negative rate of 2.9% for severe SDB. Conclusion: The NoSAS score had a good degree of differentiation for SDB and can be used as an easily applicable, subjective, and effective screening tool in a sleep clinical population in Turkey. Not only in moderate to severe SDB but also in mild SDB, the NoSAS score performed better than the other 3 screening tools.

RESUMEN

Ageing has effects both on language and gestural communication skills. Although gesture use is similar between younger and older adults, the use of representational gestures (e.g., drawing a line with fingers on the air to indicate a road) decreases with age. This study investigates whether this change in the production of representational gestures is related to individuals' working memory and/or mental imagery skills. We used three gesture tasks (daily activity description, story completion, and address description) to obtain spontaneous co-speech gestures from younger and older individuals (N = 60). Participants also completed the Corsi working memory task and a mental imagery task. Results showed that although the two age groups' overall gesture frequencies were similar across the three tasks, the younger adults used relatively higher proportions of representational gestures than the older adults only in the address description task. Regardless of age, the mental imagery but not working memory score was associated with the use of representational gestures only in this task. However, the use of spatial words in the address description task did not differ between the two age groups. The mental imagery or working memory scores did not associate with the spatial word use. These findings suggest that mental imagery can play a role in gesture production. Gesture and speech production might have separate timelines in terms of being affected by the ageing process, particularly for spatial content.

RESUMEN

OBJECTIVE: The purpose of this study was to evaluate the predictive power of the screening questionnaires including Epworth Sleepiness Scale (ESS), Berlin questionnaire (BQ) and STOP-Bang questionnaire (SBQ) to identify the high-risk patients for OSA in a sleep clinic setting considering age, gender and comorbidities. MATERIAL AND METHODS: 1003 patients who admitted to our sleep center with the preliminary diagnosis of OSA between June 2016-May 2018 were included in the study. All patients underwent in-lab polysomnographic examination and filled out ESS, Berlin and STOP-Bang questionnaires. Predictive parameters for each screening questionnaires were calculated. RESULTS: For apnea-hypopnea index (AHI) ≥5/h, the sensitivity and the specificity of the EES, BQ and SBQ were 50.6%, 89.8%, 97.9% and 56.6%, 27.3%, 16.2% respectively. The STOP-Bang questionnaire had the highest sensitivity in both males and females (99.1%, 94.8% respectively) and in the different age groups (97.3% for ≥45 age-group, 99.2% for ≥65 age-group). In the groups of patients with hypertension, diabetes mellitus, coronary artery disease, chronic obstructive pulmonary disease and asthma, the sensitivity of the STOP-Bang questionnaire was 99.5%, 100%, 99.5%, 100%, 97.4%, respectively. CONCLUSION: The STOP-Bang questionnaire had the highest sensitivity for detecting high-risk patients for OSA in a sleep clinic setting. STOP-Bang questionnaire was superior to the Berlin questionnaire and ESS in the different groups of age, gender, and comorbidities. Considering the close relationship between OSA and comorbidities, it is critical to screen patients in terms of OSA in outpatient clinics of internal medicine, cardiology, and chest disease departments. The STOP-Bang questionnaire, with its high sensitivity, may be useful for screening OSA. However, the low specificity should be improved in the questionnaire.

RESUMEN

One-hundred-six 5-year-olds' (Mage  = 5;6; SD = 0.40) were trained with second-order false belief tasks in one of the following conditions: (a) feedback with explanation; (b) feedback without explanation; (c) no feedback; (d) active control. The results showed that there were significant improvements in children's scores from pretest to posttest in the three experimental conditions even when children's age, verbal abilities, or working memory scores were controlled for. The training effect was stable at a follow-up session 4 months after the pretest. Overall, our results suggest that 5-year-olds' failures in second-order false belief tasks are due to lack of experience and that they can be helped over the threshold by exposure to many stories involving second-order false belief reasoning, including why questions.

RESUMEN

BACKGROUND: Nepal is a developing country with limited resources for health provision due to its geographic difficulties and frequent natural disasters, such as floods and earthquakes. Children are at risk of growth retardation due to inadequate food intake and unhealthy environment. Lower back pain is common among the adults and causes limitations in daily activities. MATERIAL/METHODS: A group of voluntary Turkish medical students, doctors and civil members conducted a field study, together with Nepalese doctors (MDs) and local volunteers, concerned with health-screening, intervention practices and on-site training in rural Nepal between 2013 and 2015. Physical examination of participants, together with stool examinations for parasites were done and those for whom treatment was indicated were referred to MDs who also ran a field pharmacy containing donated medications. RESULTS: Totally, 1148 individuals-725 children and 423 adults-were screened between 2013 and 2015. Musculoskeletal problems and upper respiratory tract infections were primary complaints among adults and sick children, respectively. Three-quarters of 203 collected stools had ≥ 1 parasite(s). CONCLUSIONS: Growth retardation in children observed during the study, the burden of intestinal parasites on Nepalese children and unavailability of effective health services for citizens in rural areas should direct local authorities to allocate greater resources for country's health infrastructure improvement and to provide a higher standard of childhood nutrition.

RESUMEN

Background/aim: This study was conducted to determine the critical partial oxygen pressure (pO2) value that would impair hearing function by evaluating the effects of hypoxia on hearing function in subjects diagnosed with chronic obstructive pulmonary disease (CPOD). Materials and methods: The study included 25 male and 5 female patients referred to our clinic who were diagnosed with COPD, according to spirometry and PaO2 values, and who did not show pathology upon autoscopic examination. The control group consisted of 14 female and 16 male patients who had no lung disease and were in the same age range as the COPD group. Results: A statistically significant difference was found between the two groups for distortion-product otoacoustic emission (DPOAE) (P < 0.001). The COPD group was divided into two groups according to pO2 levels (pO2 ≤ 70 and pO2 > 70) in order to find a critical pO2 level which might cause significant change at a certain audiological extent. Conclusion: Hypoxia causes long-term decline in hearing thresholds, deterioration of DPOAE results, and prolongation of I­V interpeak latency in auditory brainstem response. However, the critical oxygen level that disrupts hearing function could not be determined.

RESUMEN

Iridium(I) complexes having an imidazol-2-ylidene ligand with benzylic wingtips efficiently catalyzed the ß-alkylation of secondary alcohols with primary alcohols and acceptorless dehydrogenative cyclization of 2-aminobenzyl alcohol with ketones through a borrowing hydrogen pathway. The ß-alkylated alcohols, including cholesterol derivatives, and substituted quinolines were obtained in good yields by using a minute amount of the catalyst with a catalytic amount of NaOH or KOH under the air atmosphere, liberating water (and H2 in the case of quinoline synthesis) as the sole byproduct. Notably, this system demonstrated turnover numbers of 940 000 (for ß-alkylation of secondary alcohols with primary alcohols by using down to 0.0001 mol % = 1 ppm of the catalyst) and 9200 (acceptorless dehydrogenative cyclization of 2-aminobenzyl alcohol with ketones).
