Quality of life, craniomandibular function, and psychosocial factors related to pain and movement in patients with head and neck cancer.

PURPOSE: To describe the characteristics of and the associations between health-related quality of life, pain, craniomandibular function, and psychosocial factors related to pain and fear of movement in patients with head and neck cancer. METHODS: Seventy-eight patients diagnosed with HNC were recruited. Measurements of the maximum mouth opening range and pressure pain thresholds on the masseter muscle and the distal phalanx of the thumb were conducted, as well as a battery of self-report questionnaires were administrated, including the QoL Questionnaire (EORT QLQ-H&N35), Numeric Rating Scale (NRS), Pain Catastrophizing Scale (PCS), the Spanish translation of the Tampa Scale for Kinesiophobia for Temporomandibular Disorders (TSK-TMD), and the short version of the Craniofacial Pain and Disability Inventory (CF-PDI-11). RESULTS: The study sample (66.7% men, mean age 60.12 [11.95] years) experienced a moderate impact on their QoL levels (57.68 [18.25] EORT QLQ-H&N35) and high kinesiophobia values (20.49 [9.11] TSK-TMD). Pain was present in 41% of the patients, but only 3.8% reported severe pain. 26.4% had a restricted mouth opening range, and 34.62% showed significant catastrophism levels. There were strong positive correlations between EORT QLQ-H&N35 and CF-PDI-11 (r = 0.81), between NRS and CF-PDI-11 (r = 0.74), and between PCS and CF-PDI-11 (r = 0.66). CONCLUSION: Patients with HNC experience negative effects in their QoL, related to their impairment in craniomandibular function. Fear of movement, pain intensity, and catastrophism are associated with poorer functionality; relationships that should be considered when attempting to improve health care.

EXPRESS: Transposition and substitution letter effects in a flanker task: evidence from children and adults.

Several studies have shown that parafoveal processing is essential in reading development. In this study, we explore the effect of transposing and substituting inner and outer letters in a flanker lexical decision task administered to 78 children and 65 adults. The results show a significant interaction between the Group factor and the Flanker factor, suggesting differences in the effects of flankers for children and adults. In the case of adults, transposed and substituted letters generated benefit of the same magnitude in comparison to the unrelated condition, but of lesser magnitude than the Identity condition. In the case of children, the results show facilitation for the transposed conditions of the same magnitude as the Identity condition. However, the substitution conditions failed to generate any benefit in comparison to the unrelated condition. The results for the adults are in line with the predictions of the open bigram model, while the results for the children are explained through a developmental perspective of the dual-route architecture and open bigram framework.

Somatosensory Profiling of Patients With Cluster Headache: A Systematic Review and Meta-analysis.

The objectives were 1) to synthesize quantitative sensory testing results in cluster headache (CH) patients and to identify somatosensory differences from healthy subjects (HS), and 2) between symptomatic and asymptomatic sides in CH patients. Two independent reviewers conducted a literature search in MEDLINE, EMBASE, Web of Science, and CINAHL databases. Studies with observational designs were included. Methodological quality and risk of bias were assessed with the Newcastle Ottawa Scale. The selected studies underwent qualitative and quantitative analyses. The qualitative analysis showed inconsistent findings among multiple studies. Meta-analysis showed lower pressure pain thresholds (PPTs) on the symptomatic side of CH patients than HS in V2 (standardized mean difference [SMD] -1.01 [95% confidence interval (CI) -1.79, -.23], P = .01, I2 = 73%, n = 114), V3 (SMD -1 [95% CI -1.54, .45], P < .01, I2 = 82%, n = 354), and cervical region (SMD -1.25 [95% CI -2.07, -.44], P < .01, I2 = 84%, n = 194). Furthermore, lower PPTs than those detected in HS were found on the asymptomatic side in V3 (SMD -.77 [95% CI -1.27, -.27], P < .01, I2 = 79%, n = 354) and in the cervical region (SMD -1.13 [95% CI -1.97, -.3], P < .01, I2 = 85%, n = 194). However, no differences were found in V1 or the extratrigeminal points between these groups. No significant changes were found between symptomatic and asymptomatic sides in trigeminal and extratrigeminal regions. Mechanical hyperalgesia in the trigemino-cervical region of patients with CH could suggest the presence of central pain mechanisms. These results are of clinical relevance because their presence could be associated with a poorer prognosis, chronification, and treatment response. PERSPECTIVES: This study provides consistent findings on the somatosensory profile characterizing patients with CH. Clinicians should assess PPTs and other quantitative sensory testing variables in the trigeminal and extratrigeminal (cervical) regions.

Effect of Christmas Holidays on Type 1 Diabetes Mellitus in Users of Glucose Flash Systems.

OBJECTIVE: Christmas holidays can impact weight and glycemic control in type 2 diabetes, but their effect on type 1 diabetes (T1D) remains understudied. This study assessed how Christmas holidays affect individuals with T1D who use flash continuous glucose monitoring systems. METHODS: This retrospective study involved 812 adults diagnosed with T1D recruited from 3 hospitals. Clinical, anthropometric, and socioeconomic data were collected. Glucose metrics from 14 days before January 1st, and before December 1st and February 1st as control periods, were recorded. Analyses adjusted for multiple variables were conducted to assess the holiday season's impact on glycemic control. RESULTS: The average time in range during the holidays (60.0 ± 17.2%) was lower compared to December (61.9 ± 17.2%, P < .001) and February (61.7 ± 17.7%, P < .001). Time above range (TAR > 180 mg/dL) was higher during Christmas (35.8 ± 18.2%) compared to December (34.1 ± 18.3%, P < .001) and February (34.2 ± 18.4%, P < .001). Differences were also observed in TAR >250 mg/dL, coefficient of variation, and average glucose (P < .05). No differences were found in time below range or other metrics. Linear regression models showed that the holidays reduced time in range by 1.9% (ß = -1.92, P = .005) and increased TAR >180 mg/dL by 1.8% (ß = 1.75, P = .016). CONCLUSION: Christmas holidays are associated with a mild and reversible deterioration in glucose metrics among individuals with T1D using flash continuous glucose monitoring, irrespective of additional influencing factors. These discoveries can be useful to advise individuals with diabetes during the festive season and to recognize potential biases within studies conducted during this timeframe.

Hyperalgesia, Increased Temporal Summation and Impaired Inhibitory Mechanisms in Episodic and Chronic Cluster Headache: An Observational Study.

Cluster Headache (CH) is a primary headache that causes severe pain. Some evidence suggests that central mechanisms might be involved. The objective of this study was (1) to compare hyperalgesia signs, temporal summation and conditioned pain modulation among episodic (ECH) and chronic CH (CCH) patients and controls, (2) to compare these factors between sides in the patient groups and (3) to compare the psychophysical variables between the groups. This cross-sectional study included 71 subjects divided into three groups (ECH, CCH and controls). Pressure pain thresholds, temporal summation, conditioned pain modulation and other psychosocial variables were measured. The ANOVA showed differences for all physical outcome measures (p < 0.05). Bonferroni post hoc analyses showed differences when comparing the patient groups with the healthy subjects (p < 0.05), with large effect sizes (d > 0.8). No differences between the patient groups were found for almost all the variables (p > 0.05). Significant differences for all the variables were detected when comparing the symptomatic and non-symptomatic sides in both the ECH and CCH groups (p < 0.05). The ECH and CCH groups showed mechanical hyperalgesia, increased temporal summation and impaired inhibitory mechanisms compared to the controls. Side-to-side differences were also detected within the patient groups. Patients with CCH had poorer sleep quality and quality of life than the controls.

Impact of socioeconomic status on chronic control and complications of type 1 diabetes mellitus in users of glucose flash systems: a follow-up study.

BACKGROUND: This study investigates the association between socioeconomic status (SES) and glycemic control in individuals with type 1 diabetes (T1D) using flash glucose monitoring (FGM) devices within a public health system where these technologies are freely available and utilized according to recommended guidelines. METHODS: A follow-up study of 1060 adults (mean age 47.4 ± 15.0 years, 49.0% women) with T1D, receiving care at three Spanish university hospitals that regularly employ the FGM system. SES was assessed using the Spanish Deprivation Index and the average annual net income per person. Glycemic data were collected over a 14-day follow-up period, including baseline glycated hemoglobin (HbA1c) levels prior to sensor placement, the last available HbA1c levels, and FGM-derived glucose metrics. Individuals with sensor usage time < 70% were excluded. Chronic micro and macrovascular complications related to diabetes were documented. Regression models, adjusted for clinical variables, were employed to determine the impact of SES on optimal sensor control (defined as time in range (TIR) ≥ 70% with time below range < 4%) and disease complications. RESULTS: The average follow-up was of 2 years. The mean TIR and the percentage of individuals with optimal control were higher in individuals in the highest SES quartile (64.9% ± 17.8% and 27.9%, respectively) compared to those in the lowest SES quartile (57.8 ± 17.4% and 12.1%) (p < 0.001). Regression models showed a higher risk of suboptimal control (OR 2.27, p < 0.001) and ischemic heart disease and/or stroke (OR 3.59, p = 0.005) in the lowest SES quartile. No association was observed between SES and the risk of diabetic nephropathy and retinopathy. FGM system improved HbA1c levels across all SES quartiles. Although individuals in the highest SES quartile still achieved a significantly lower value at the end of the follow-up 55 mmol/mol (7.2%) compared to those in the lowest SES quartile 60 mmol/mol (7.6%) (p < 0.001), the significant disparities in this parameter between the various SES groups were significantly reduced after FGM technology use. CONCLUSIONS: Socioeconomic status plays a significant role in glycemic control and complications in individuals with T1D, extending beyond access to technology and its proper utilization. The free utilization of FGM technology helps alleviate the impact of social inequalities on glycemic control.

Intrafamilial phenotypic heterogeneity in siblings with pseudohypoparathyroidism 1B due to maternal STX16 deletion.

OBJECTIVES: Pseudohypoparathyroidism (PHP1B) is most commonly caused by epigenetic defects resulting in loss of methylation at the GNAS locus, although deletions of STX16 leading to GNAS methylation abnormalities have been previously reported. The phenotype of this disorder is variable and can include hormonal resistances and severe infantile obesity with hyperphagia. A possible time relationship between the onset of obesity and endocrinopathies has been previously reported but remains unclear. Understanding of the condition's natural history is limited, partly due to a scarcity of literature, especially in children. CASE PRESENTATION: We report three siblings with autosomal dominant PHP1B caused by a deletion in STX16 who presented with early childhood onset PTH-resistance with normocalcemia with a progressive nature, accompanied by TSH-resistance and severe infantile obesity with hyperphagia in some, not all of the affected individuals. CONCLUSIONS: PHP1B from a STX16 deletion displays intrafamilial phenotypic variation. It is a novel cause of severe infantile obesity, which is not typically included in commercially available gene panels but must be considered in the genetic work-up. Finally, it does not seem to have a clear time relationship between the onset of obesity and hormonal resistance.

Variational Bayes inference for hidden Markov diagnostic classification models.

Diagnostic classification models (DCMs) can be used to track the cognitive learning states of students across multiple time points or over repeated measurements. This study developed an effective variational Bayes (VB) inference method for hidden Markov longitudinal general DCMs. The simulations performed in this study verified the validity of the proposed algorithm for satisfactorily recovering true parameters. Simulation and applied data analyses were conducted to compare the proposed VB method to Markov chain Monte Carlo (MCMC) sampling. The results revealed that the parameter estimates provided by the VB method were consistent with the MCMC method with the additional benefit of a faster estimation time. The comparative simulation also indicated differences between the two methods in terms of posterior standard deviation and coverage of 95% credible intervals. Thus, with limited computational resources and time, the proposed VB method can output estimations comparable to that of MCMC.

Scans per day as predictors of optimal glycemic control in people with type 1 diabetes mellitus using flash glucose monitoring: what number of scans per day should raise a red flag?

AIMS: This study aimed to determine the minimum frequency of flash glucose monitoring (FGM) scans necessary for optimal glycemic control in patients with type 1 diabetes (T1D). METHODS: Data were collected from 692 patients (47.5% female, with a median age of 47.4 years) who used FGM systems daily and recorded their clinical variables and device data. RESULTS: Logistic regression models showed that performing more than 12 scans per day was associated with improved T1D control (OR = 4.22, p < 0.001) and a reduction in HbA1c (7.6 vs 7.0%, 60-53 mmol/mol p < 0.001). However, those performing less than 6 scans showed no improvement in HbA1c (7.9 vs 7.8%, 63-61 mmol/mol p = 0.514). Thirteen daily scans were determined as the optimal cutoff point for predicting optimal glycemic control using a maximally selected rank algorithm. Significant reductions were observed in mean glucose (< 0.001), coefficient of variation (< 0.001), HbA1c (< 0.001), and an increase in TIR (< 0.001) in patients who performed more than 12 daily scans. CONCLUSIONS: The results suggest that a higher frequency of daily scans by T1D patients using FGM systems leads to improved chronic glycemic control. The minimum recommended frequency for optimal control is 13 scans per day, and more than 6 daily scans are needed to improve HbA1c.

Distraction osteogenesis versus induced membrane technique for infected tibial non-unions with segmental bone loss: a systematic review of the literature and meta-analysis of available studies.

INTRODUCTION: Infected tibial non-unions with associated bone loss can be challenging to manage. At present, the two main methods utilized in the management of these fractures include the Ilizarov technique of Distraction Osteogenesis (DO) using external fixator devices, or alternatively, the Induced Membrane Technique (IMT), devised by Masquelet. As there is a paucity of data directly comparing the outcomes of these techniques, there is no universal agreement on which strategy a surgeon should choose to use. AIMS: This systematic review and meta-analysis aimed to summarize the outcomes of both DO and IMT, in terms of primary outcomes (bone union and infection elimination), and secondary outcomes (complication rates and functional outcomes). METHODS: A PRISMA strategy was used. Medline, Web of Science, Cochrane Central Register of Controlled Trials (CENTRAL), and Google Scholar library databases were interrogated using pre-defined MeSH terms and Boolean operators. Quality of evidence was evaluated using OCEBM and GRADE systems. RESULTS: Thirty-two studies with 1136 subjects met the inclusion criteria. With respect to the primary outcomes of interest, union was observed in 94.6% (DO method) and 88.0% (IMT method); this difference, however, was not significant between the two techniques (p = 0.45). In addition, infection elimination rates were also higher in the Ilizarov DO group when compared to Masquelet (Mq) IMT (93.0% vs 80.4% respectively). Again, no significant difference was observed (p = 0.06). For all secondary outcomes assessed (unplanned re-operations, re-fracture rates amputation rate), no statistically significant differences were documented between the treatment options. CONCLUSION: This study demonstrated that there is no clinical difference in outcomes for patients treated with Ilizarov DO versus Mq IMT techniques. The evidence base at present is relatively sparse and, therefore, we would recommend for further Level I studies to be conducted, to make more meaningful conclusions.

Fabricación y caracterización de pozos cuánticos para el estudio de la interacción luz-materia / Fabrication and characterization of quantum wells for the study of light-matter interaction

RESUMEN Los pozos cuánticos representan la base de una gran variedad de dispositivos electrónicos, entre ellos los ledes, láseres, fotodetectores y moduladores. Las propiedades optoelectrónicas de estos sistemas dependen de su composición química y del espesor de las capas crecidas. Por dicha razón, es necesario tener un control preciso durante su crecimiento. El presente trabajo tuvo como objetivo inducir el crecimiento epitaxial de pozos cuánticos intrínsecos (sin ningún dopaje) asimétricos acoplados y desacoplados de AlGaAs/ GaAs/AlGaAs, así como, establecer su caracterización mediante técnicas de espectroscopía óptica, como lo son la reflectancia diferencial, también conocida como espectroscopía de reflectancia anisotrópica (RAS) y la fotoluminiscencia (PL). Se realizó un estudio experimental de las interacciones entre niveles de energía en los pozos cuánticos asimétricos acoplados. Este tipo de estructuras son especialmente interesantes por permitir la formación y observación, no solo de excitones directos, dentro del mismo pozo, sino también, de excitones y triones indirectos, que se forman entre electrones de un pozo y huecos de otro pozo vecino (Transiciones intra-QW). Se hicieron crecer tres pozos intrínsecos, basados en arseniuro de galio (GaAs): un pozo individual (desacoplado) y un par de pozos asimétricos acoplados, a través de epitaxia por haces moleculares (MBE). Se observó el efecto del rompimiento de simetría (de D2d a C2v) en las propiedades espintrónicas de la estructura, a través de PL y RAS, a una temperatura de ~ 30 K. Se lograron establecer las técnicas y métodos necesarios para el crecimiento de pozos cuánticos intrínsecos, que constituyen la base para la creación de dispositivos y estructuras más complejas. El uso de técnicas espectroscópicas permitió demostrar la presencia de anisotropías ópticas, que repercuten en el comportamiento del espín de los excitones en pozos cuánticos.

ABSTRACT Quantum Wells are the basis for a great variety of electronic devices such as leds, lasers, photodetectors and modulators. Their optoelectronic properties depend on their chemical composition and the thickness of each layer. Therefore, a precise control during their growth is needed. This work has the objective of presenting the epitaxial growth of coupled and uncoupled asymmetric AlGaAs/GaAs/AlGaAs quantum wells and their characterization using optical techniques such as reflectance anisotropy spectroscopy (RAS) and photoluminescence (PL). An experimental study of the different interactions between the confined levels of energy in coupled quantum wells was carried on. This kind of structures is of special interest because they allow the formation and observation not only of direct excitons and trions inside a single quantum well, but of indirect excitons and trions, which are only formed by electrons of one quantum well and holes of the neighbor quantum well (IntraQW transitions). Three intrinsic quantum wells based on gallium arsenide (GaAs) were grown by molecular beam epitaxy (MBE), one single QW and a pair of coupled asymmetric QWs. The effect of breaking symmetry (from de D2d a C2v) on the spintronic properties of the structure was observed by RAS and PL measurements at ~ 30 K. The main techniques and methods for the growth of intrinsic quantum wells were established, which are the basis for the creation of devices with more complex structures. The use of spectroscopic techniques for the study of quantum wells allowed the demonstration of the presence of optical anisotropies that influence the behavior of exciton's spins at quantum wells.

Reliability and Responsiveness of a Novel Device to Evaluate Tongue Force.

BACKGROUND: Measurements of tongue force are important in clinical practice during both the diagnostic process and rehabilitation progress. It has been shown that patients with chronic temporomandibular disorders have less tongue strength than asymptomatic subjects. Currently, there are few devices to measure tongue force on the market, with different limitations. That is why a new device has been developed to overcome them. The objectives of the study were to determine the intra- and inter-rater reliability and the responsiveness of a new low-cost device to evaluate tongue force in an asymptomatic population. MATERIALS AND METHODS: Two examiners assessed the maximal tongue force in 26 asymptomatic subjects using a developed prototype of an Arduino device. Each examiner performed a total of eight measurements of tongue force in each subject. Each tongue direction was measured twice (elevation, depression, right lateralization, and left lateralization) in order to test the intrarater reliability. RESULTS: The intrarater reliability using the new device was excellent for the measurements of the tongue force for up (ICC > 0.94), down (ICC > 0.93) and right (ICC > 0.92) movements, and good for the left movement (ICC > 0.82). The SEM and MDC values were below 0.98 and 2.30, respectively, for the intrarater reliability analysis. Regarding the inter-rater reliability, the ICC was excellent for measuring the tongue up movements (ICC = 0.94), and good for all the others (down ICC = 0.83; right ICC = 0.87; and left ICC = 0.81). The SEM and MDC values were below 1.29 and 3.01, respectively, for the inter-rater reliability. CONCLUSIONS: This study showed a good-to-excellent intra- and inter-reliability and good responsiveness in the new device to measure different directions of tongue force in an asymptomatic population. This could be a new, more accessible tool to consider and add to the assessment and treatment of different clinical conditions in which a deficit in tongue force could be found.

A Phase III, multicenter, randomized, double-blind, active comparator-controlled study to evaluate the safety, tolerability, and immunogenicity of V114 compared with PCV13 in healthy infants (PNEU-PED-EU-1).

BACKGROUND: V114 (15-valent pneumococcal conjugate vaccine [PCV]) contains all serotypes in 13-valent PCV (PCV13) and additional serotypes 22F and 33F. This study evaluated safety and immunogenicity of V114 compared with PCV13 in healthy infants, and concomitant administration with DTPa-HBV-IPV/Hib and rotavirus RV1 vaccines. METHODS: V114 and PCV13 were administered in a 2+1 schedule at 2, 4, and 11-15 months of age. Adverse events (AEs) were collected on Days 1-14 following each vaccination. Serotype-specific anti-pneumococcal immunoglobulin G (IgG) was measured 30 days post-primary series (PPS), immediately prior to a toddler dose, and 30 days post-toddler dose (PTD). Primary objectives included non-inferiority of V114 to PCV13 for 13 shared serotypes and superiority of V114 to PCV13 for the two additional serotypes. RESULTS: 1184 healthy infants 42-90 days of age were randomized 1:1 to V114 (n = 591) or PCV13 (n = 593). Proportions of participants with solicited AEs and serious AEs were comparable between vaccination groups. V114 met pre-specified non-inferiority criteria for all 13 shared serotypes, based on the difference in proportions of participants with serotype-specific IgG concentrations ≥0.35 µg/mL (response rate; lower bound of two-sided 95% confidence interval [CI] >-10.0) and IgG geometric mean concentration (GMC) ratios (lower bound of two-sided 95% CI >0.5), and pre-specified superiority criteria for serotypes 22F and 33F (lower bound of two-sided 95% CI >10.0 for response rates and >2.0 for GMC ratios). Antibody responses to DTPa-HBV-IPV/Hib and RV1 vaccines met pre-specified non-inferiority criteria, based on antigen-specific response rates to DTPa-HBV-IPV/Hib and anti-rotavirus IgA geometric mean titers. CONCLUSIONS: After a 2+1 schedule, V114 elicited non-inferior immune responses to 13 shared serotypes and superior responses to the two additional serotypes compared with PCV13, with comparable safety profile. These results support the routine use of V114 in infants. TRIAL REGISTRATION: ClinicalTrials.gov: NCT04031846; EudraCT: 2018-003787-31.

Psychotropic consumption before and during COVID-19 in Asturias, Spain.

BACKGROUND: Spain as multiple other countries has been experiencing an increasing and sustained trend in the use of psychotropic medications since the mid 90s. Recent studies show public health measures implemented to control SARS-Cov2, such as mobility restrictions and the shutdown of nonessential activities increased mental suffering, even contributing to a higher number of anxiety, depression and insomnia disorders that could lead to an increase in the consumption of psychotropics. The aims were: 1) Evaluate the temporal trend in psychotropic consumption by pharmacological subgroup, sex, and age group 2) Estimate the effect of the COVID-19 pandemic in the use of psychotropic drugs. METHODS: We conducted a retrospective observational study, retrieving all prescriptions of anxiolytics, hypnotics and sedatives, and antidepressants dispensed in pharmacies of Asturias (Northern Spain) for Primary Care patients for the period 2018-2021. We presented the data expressed in Daily Defined Doses (DDDs) for 1000 persons/day (DHD). To estimate changes in DHDs by year and age group we conducted two multiple linear regressions (one for males and one for females) for every pharmacological subgroup studied. Changes were considered statistically significant when the regression coefficient was p < 0.05. We used the Software R 4.1.0. RESULTS: For the studied period, the highest DHDs are for antidepressants, although all of the subgroups experienced an increase in consumption rates. Women consumed more psychotropic drugs than men. In 2021, 372 out of every 1000 women were taking daily 1 DDD of these drugs versus 184 out of every 1000 men. Consumption rates for all psychotropic drugs progressively increases with age. Conversely, the biggest increases in consumption were among the youngest age groups (0-14 and 15-29 years) for women, while for men there is more variability. The regression models suggest an upward trend in psychotropic consumption during all the period, especially remarkable from 2020, for both genders and all age groups. CONCLUSIONS: - The consumption of psychotropic drugs has gradually increased over the last 4 years, with a significant boost starting in 2020 for both sexes, matching the start of the SARS-COV2 pandemic and the implementation of strict Public Health measures to contain it. - The increase observed on children and adolescents is a matter of concern.

Leuprolide Protects Ovarian Reserve in Adolescents Undergoing Gonadotoxic Therapy.

Purpose: Treatment sequelae compromising reproductive health are highly prevalent in childhood cancer survivors, and a main determinant of health and quality of life. Follicular reserve determines ovarian function life span; thus, its preservation is important in the care of female survivors. Anti-Müllerian hormone (AMH) is a biomarker to measure functional ovarian reserve. We aimed to evaluate the effect of leuprolide during gonadotoxic therapy on pubertal females' post-treatment functional ovarian reserve using AMH levels. Methods: We conducted a single-center retrospective study including all pubertal females who had undergone gonadotoxic treatments between January 2010 and April 2020, and had an AMH level after completion of therapy. We used multivariable linear regressions to compare AMH-level beta coefficients in patients stratified by gonadotoxic risk, adjusting for leuprolide use. Results: Fifty-two females meeting study eligibility were included, of which 35 received leuprolide. The use of leuprolide was associated with higher post-treatment AMH levels in the lower gonadotoxic risk group (beta 2.74, 95% CI 0.97-4.51; p = 0.004). This association was lost in the higher gonadotoxic risk groups. Conclusions: Leuprolide may have a protective effect on the functional ovarian reserve. However, this is limited by increasing treatment gonadotoxicity. Larger, prospective studies are needed to elucidate the potential benefits of gonadotropin-releasing hormone agonist on preservation of ovarian reserve among children receiving gonadotoxic therapies, as cancer survivors.

Diversidad de especies de Candida recuperadas de la cavidad bucal de pacientes oncológicos en Barranquilla, Colombia Candida spp bucal y cáncer / Species diversity of the genus Candida in the oral cavity of cancer patients in Barranquilla, Colombia

Resumen Se caracterizaron especies de Candida recuperadas de la cavidad bucal de pacientes oncológicos en una institución prestadora de salud de Barranquilla, Colombia. La investigación tuvo un diseño de corte transversal, mediante un muestreo a conveniencia se seleccionaron 60 pacientes oncológicos con candidiasis oral. Las muestras obtenidas se cultivaron en agar Sabouraud cloranfenicol, CHROMagar® Candida y agar Sabouraud dextrosa. Los microorganismos aislados se identificaron y se estableció el perfil de sensibilidad a los antifúngicos. Se aplicó estadística descriptiva, prueba de X 2 y análisis bivariado utilizando el programa Statgraphics Centurión XVII, con razón de momios (OR) para probabilidad de ocurrencia. Se identificaron un total de 107 cepas de Candida correspondientes a 15 especies, distribuidas del siguiente modo: C. albicans 23%, C. glabrata 18%, C. tropicalis 13%, C. krusei 10%, C. intermedia y C. lipolytica con 1,5%. En 77% de los casos estuvieron implicadas especies diferentes de C. albicans. Se identificó la existencia de relación entre cáncer del sistema reproductor y C. guilliermondii (p = 0,0001, < 0,05; OR 17) y entre C. colliculosa y cánceres respiratorios (p = 0,0003 < 0,05; OR 19,5). El 99% de las especies de Candida identificadas fueron sensibles a los antifúngicos: fluconazol, voriconazol, caspofungina y micafungina. Solo una cepa de C. krusei fue resistente. Se concluye que existió diversidad de especies de Candida en la cavidad bucal de pacientes oncológicos, ya sea como colonizantes únicos o en combinación, de modo que más de una especie de Candida podría ser responsable de la infección micótica en la cavidad bucal de estos enfermos.

Abstract Candida spp. was characterized in the oral cavity of cancer patients in a health care center in Barranquilla, Colombia. This is a cross-sectional investigation including 60 oncological patients with oral candidiasis, selected by convenience sampling, from whom samples were subjected to culture in Sabouraud chloramphenicol agar, CHROMagar® Candida and Sabouraud dextrose agar were taken. The antifungal susceptibility profile was then identified and established. Descriptive statistics, Chi square test, and bivariate analysis were conducted using the Statgraphics Centurion XVII software with odds ratio (OR) for the probability of occurrence. A total of 107 Candida strains were identified belonging to 15 species, C. albicans with 23%, C. glabrata with 18%, C. tropicalis 13%, C. krusei 10%, C intermedia, and C. lipolytica with 1.5%. Species other than C. albicans were identified in 77% of the cases. A relationship between reproductive system cancer and C. guilliermondii was identified (p = 0.0001, <0.05) OR: 17.0. Between C. colliculosa and respiratory cancer (p = 0.0003, <0.05) OR 19.5. With regard to antifungal susceptibility, 99% of the identified Candida species were susceptible to the following antifungals: fluconazole, voriconazole, caspofungin, and micafungin. Only one strain of C. krusei was resistant. It is concluded that there was a diversity of Candida species, either single or mixed in cancer patients, which could determine that only one species is not responsible for fungal infection in the oral cavity.

Effectiveness of Physical Therapy in Orthognathic Surgery Patients: A Systematic Review of Randomized Controlled Trials.

Orthognathic surgery (OS) can present many complications that affect patients' rehabilitation. However, there have been no systematic reviews that assessed the effectiveness of physiotherapy interventions in the postsurgical rehabilitation of OS patients. The aim of this systematic review was to analyze the effectiveness of physiotherapy after OS. The inclusion criteria were randomized clinical trials (RCTs) of patients who underwent OS and who received therapeutic interventions that included any physiotherapy modality. Temporomandibular joint disorders were excluded. After the filtering process, five RCTs were selected from the 1152 initially obtained (two had acceptable methodological quality; three had insufficient methodological quality). The results obtained showed that the effects of the physiotherapy interventions studied in this systematic review on the variables of range of motion, pain, edema and masticatory muscle strength were limited. Only laser therapy and LED showed a moderate level of evidence in the postoperative neurosensory rehabilitation of the inferior alveolar nerve compared with a placebo LED intervention.

Differences between Maximum Tongue Force in Women Suffering from Chronic and Asymptomatic Temporomandibular Disorders-An Observational Study.

Background: Temporomandibular disorders are craniofacial disorders characterized by the presence of chronic pain in masticatory muscles, with higher incidence in the women population. There is little research that has studied tongue force related to temporomandibular disorders, but there are a lot of studies that have demonstrated the impact of tongue force in vital functions, such as chewing, swallowing, phonation, or breathing. According to this, the aim of this study was to compare the maximum force of the tongue between females with chronic temporomandibular disorders and asymptomatic females. We also wanted to establish whether any relationship existed between the pain and fatigue versus the maximum force developed in females with chronic temporomandibular disorders. Material and methods: A cross-sectional study of 67 women between the ages of 18 and 65 years old was performed. The included women were assigned to one of two groups, according to whether they had chronic temporomandibular disorders or not. The procedure was the same for both groups. Outcome measures included the maximum tongue force, intensity of perceived orofacial pain, and intensity of perceived orofacial fatigue. Results: The results showed significant statistical differences for the maximum tongue force measurement between the chronic temporomandibular disorders group and the control group (p < 0.05) for all the movements, except the lip pressure measurement. Furthermore, the analysis revealed significant statistical differences between the intensity of perceived orofacial fatigue between the groups (p < 0.05). Moreover, the data showed no significant correlations between variables. Conclusion: The study found significant differences in maximum tongue force when comparing women with chronic temporomandibular disorders and asymptomatic women (being superior in these). Likewise, we found that the intensity of perceived orofacial fatigue after tongue exercises showed significant differences between groups. However, this study reveals no correlations between the intensity of perceived orofacial pain and fatigue and the maximum tongue force.

[Species diversity of the genus Candida in the oral cavity of cancer patients in Barranquilla, Colombia]. / Diversidad de especies de Candida recuperadas de la cavidad bucal de pacientes oncológicos en Barranquilla, Colombia.

Candida spp. was characterized in the oral cavity of cancer patients in a health care center in Barranquilla, Colombia. This is a cross-sectional investigation including 60 oncological patients with oral candidiasis, selected by convenience sampling, from whom samples were subjected to culture in Sabouraud chloramphenicol agar, CHROMagar® Candida and Sabouraud dextrose agar were taken. The antifungal susceptibility profile was then identified and established. Descriptive statistics, Chi square test, and bivariate analysis were conducted using the Statgraphics Centurion XVII software with odds ratio (OR) for the probability of occurrence. A total of 107 Candida strains were identified belonging to 15 species, C. albicans with 23%, C. glabrata with 18%, C. tropicalis 13%, C. krusei 10%, C intermedia, and C. lipolytica with 1.5%. Species other than C. albicans were identified in 77% of the cases. A relationship between reproductive system cancer and C. guilliermondii was identified (p = 0.0001, <0.05) OR: 17.0. Between C. colliculosa and respiratory cancer (p = 0.0003, <0.05) OR 19.5. With regard to antifungal susceptibility, 99% of the identified Candida species were susceptible to the following antifungals: fluconazole, voriconazole, caspofungin, and micafungin. Only one strain of C. krusei was resistant. It is concluded that there was a diversity of Candida species, either single or mixed in cancer patients, which could determine that only one species is not responsible for fungal infection in the oral cavity.
