RESUMO

Objective@#This pilot human trial demonstrates the ability of the investigational newborn hearing screening device to provide acoustic stimulation to produce evoked potentials, as well as its ability to capture and acquire auditory evoked potentials, especially the auditory brainstem response (ABR) wave V. This pilot study also demonstrates the ease of recognizing and identifying ABR waves in the graphical presentation of the evoked potentials over time. @*Methods@#Fourteen normal-hearing adults or a total of twenty-eight (28) normal-hearing adult ears underwent auditory brainstem response testing using the investigational hearing screening device. A commercially available auditory brainstem response detection device was used to confirm that the acquired ABR waves of the investigational device are normal. The ABR waves displayed by the investigation device were also reviewed by the clinical audiologists to determine their recognizability and identifiability. @*Results@#The pilot trial demonstrates the ability of the investigational newborn hearing screening device in providing acoustic stimulation to produce evoked potentials, and in acquiring and capturing ABR waves, specifically the wave V, among normal-hearing adult ears. The clinical audiologists recognized and identified the ABR wave V among the evoked potentials at 40dB, 60dB, and 80dB acoustic stimulation. About eighty-nine percent (89.2%) of all ears tested had identifiable and recognizable wave V upon acoustic stimulation at 40dB. @*Conclusion@#The investigational hearing screening device: (1) can provide acoustic stimulation to produce evoked potentials, (2) can accurately capture and acquire these evoked potentials, (3) can present these evoked potentials in a voltage per time graphical display which an audiologist and trained HCP can easily read and interpret (diagnostic ABR), and (4) can present wave V auditory brainstem potentials that can be easily identified by an audiologist and trained HCP (screening ABR).

RESUMO

Objectives@#Responding to the reality of neonate patients with delayed childhood development due to late diagnosis of and intervention on hearing impairment, this study aims to determine the features based on time-frequency domain of auditory brainstem response (ABR) signals and to test the protocol on ABR signals from PhysioNet. @*Methods@#This is done by pre-processing, performing time-frequency analysis, and characterizing hearing impairment using the dominant features of the ABR. In this study, normal (N) and hearing impaired (HI) ABR adult human signals were acquired from Physionet.org, a publicly available database. Considering its high signal-to-noise ratio, numerous filters and transformations were applied to extract the ABR. Consequently, the features acquired — dominant frequency and bigrams, were used as data classifiers. @*Results@#Initial results using only N classifiers, that is features from the Normal dataset, and bandpass Chebyshev filter with a lower cut-off frequency of 60 Hz show that the tests yielded low to middle sensitivity. Further tests were done to improve the sensitivity that incorporated the HI classifiers, used data filtered with a low cut-off frequency of 300 Hz, and data divided per stimulus intensity level. @*Conclusion@#Conclusions made are 1) data with both N and HI classifiers have higher sensitivity than those using only N classifiers, 2) data with a Chebyshev cut-off frequency of 300 Hz have a higher sensitivity than those with 60 Hz, and 3) data divided per intensity level have a higher sensitivity than data analyzed as a whole, and that features with stimulus intensity in middle ranges have a better distinction between HI and N patients.

RESUMO

Objective@#To assess the usage of the “Baah” Test compared to the AABR (Automated Auditory Brainstem Response) in detecting hearing loss of neonates in the community setting. @*Methods@#This is a retrospective cross-sectional study. The targeted sample population are infants less than a month old who underwent screening at a testing facility in Malolos, Bulacan spanning the years 2011 and 2012. @*Results@#A total of 201 infants were included in the study, with a mean age of 10.77 days with a standard deviation of 7.79. The ratio of males to females was almost equal at 1:1.01. For infants who passed hearing screening on at least one ear, 96% (193 infants) correlated with the results of “Baah” testing. For those with bilateral refer results on AABR, 4 out of the 6 correlated with the “Baah” Test. @*Conclusion@#There is potential in using the “Baah” Test as a tool for hearing loss assessment of infants in situations wherein the usual hearing screening tests are inaccessible. It makes use of little resources, and though it does have its limitations in assessing for unilateral hearing loss (as the test cannot test ears in isolation), it would be able to identify infants likely to have bilateral hearing loss.

RESUMO

Objective@#To determine the accuracy, sensitivity, specificity, positive predictive values, and use of the Reflexive Behavioral “Baah” Test and NHSRC Level 1 and Level 2 Questionnaires in detecting hearing impairment in rural health communities. @*Methods@#This was a prospective cross-sectional study conducted at the rural health unit of five municipalities. Infants less than six months old were screened for hearing impairments using the OAE device (standard), the Reflexive Behavioral “Baah” test, and the NHSRC Level 1 and Level 2 Questionnaires. The “Baah” test and the filling out of the NHSRC Level 1 and 2 Questionnaires were done by trained health workers while OAE was done by an audiologist. @*Results@#A total of 103 babies, with a mean age of 41.9 days at the time of testing and a male to female ratio of 1.02:1 (52 males and 51 females) were tested. A hearing impairment prevalence of 4.9% (5 out of 103) was noted. The “Baah” test showed to have a sensitivity of 60%, specificity of 97.96% and an accuracy rate of 96.12%. The NHSRC Level 1 and Level 2 Questionnaires showed sensitivity, specificity, and accuracy rate of 40%, 67.35% and 66.02%, respectively for the former and 40%, 85.71% and 83.50%, respectively for the latter. Analysis of the complimentary use of the NHSRC Level 1 and Level 2 Questionnaires with the “Baah” test also showed no significant improvement to using the “Baah” test as a stand-alone screening tool with sensitivity, specificity, and accuracy of 60%, 67.35% and 66.99%, respectively for the “Baah” test and Level 1 Questionnaire, and 60%, 83.67% and 82.52%, respectively for the “Baah” test and Level 2 Questionnaire. @*Conclusion@#The Reflexive Behavioral “Baah” test is a potentially accurate, sensitive, specific, and acceptable standalone hearing screening test to identify infants with higher risk of hearing impairment in the rural health community setting. On the other hand, the use of the NHSRC Questionnaires as a stand-alone or complementary tool for “Baah” is unnecessary as it results to more false positive and false negative results.

RESUMO

Background@#Universal newborn hearing screening is mandated in the Philippines through the Universal Newborn Hearing Screening and Intervention Act of 2009 (RA 9709). Newborn hearing screening (NBHS) centers are required to perform screening tests, compile and submit data on screened newborns, and advise parents on the subsequent steps after NBHS.@*Objective@#The study aimed to conduct a survey of the implementation of the Universal Newborn Hearing Screening and Intervention Program (UNHSIP) in the different regions of the country; and assess the information technology (IT) capabilities of hearing centers.@*Methods@#Fifty-one NBHS centers across twelve regions were surveyed through on-site inspections in 2016. Data was gathered on the centers’ testing capability, staffing, access to specialists, use of local protocols, connectivity, and IT capabilities. @*Results@#All surveyed centers followed the recommended protocols of the Manual of Operations of the Universal Newborn Hearing Screening and Intervention Act of 2009 (RA 9709). Among the 12 regions visited, only five (41.67%) had Category C centers with confirmatory testing and early amplification services as recommended. Majority of facilities (96.1%) were staffed by trained and certified personnel. A small percentage had access to subspecialists such as clinical audiologists (39.2%) and speech-language pathologists (23.5%). All facilities had computer access, but only 58.8% had internet access. Majority (94.1%) of the centers visited were not using the recommended data submission methods, specifically the use of registry cards and the online registry. Only 27.5% of centers had data on newborns who underwent confirmatory testing or early intervention. @*Conclusion@#Facilities were found to be compliant to NBHS screening protocols and majority complied with certification requirements for staff; but were found to be non-compliant with use of registry cards or the online registry. Majority of centers were able to contact the parents of neonates who did not pass newborn screening, but had no system to track outcomes. Lack of confirmatory and early intervention services in identified areas emphasize the need for development of regional centers. It is recommended that measures to improve the utilization of the online registry are taken.

RESUMO

Background@#Many studies have evaluated the prevalence of different reasons for retraction in samples of retraction notices. We aimed to perform a systematic review of such empirical studies of retraction causes. @*Methods@#The PubMed/MEDLINE database and the Embase database were searched in June 2023. Eligible studies were those containing sufficient data on the reasons for retraction across samples of examined retracted notices. @*Results@#A 11,181 potentially eligible items were identified, and 43 studies of retractions were included in this systematic review. Studies limited to retraction notices of a specific subspecialty or country, journal/publication type are emerging since 2015. We noticed that the reasons for retraction are becoming more specific and more diverse. In a meta-analysis of 17 studies focused on different subspecialties, misconduct was responsible for 60% (95% confidence interval [CI], 53–67%) of all retractions while error and publication issues contributed to 17% (95% CI, 12–22%) and 9% (95% CI, 6–13%), respectively. The end year of the retraction period in all included studies and the proportion of misconduct presented a weak positive association (coefficient = 1.3% per year, P = 0.002). @*Conclusion@#Misconduct seems to be the most frequently recorded reason for retraction across empirical analyses of retraction notices, but other reasons are not negligible. Greater specificity of causes and standardization is needed in retraction notices.

RESUMO

Objective@#Schizophrenia is associated with impairment in multiple cognitive domains. There is a paucity of research on the effect of prolonged illness duration (≥ 15 years) on cognitive performance along multiple domains. In this pilot study, we used the Global Neuropsychological Assessment (GNA), a brief cognitive battery, to explore the patterns of cognitive impairment in recent-onset (≤ 2 years) compared to chronic schizophrenia (≥ 15 years), and correlate cognitive performance with brain morphometry in patients and healthy adults. @*Methods@#We assessed cognitive performance in patients with recent-onset (n = 17, illness duration ≤ 2 years) and chronic schizophrenia (n = 14, duration ≥ 15 years), and healthy adults (n = 16) using the GNA and examined correlations between cognitive scores and gray matter volumes computed from T1-weighted magnetic resonance imaging images. @*Results@#We observed cognitive deficits affecting multiple domains in the schizophrenia samples. Selectively greater impairment of perceptual comparison speed was found in adults with chronic schizophrenia (p = 0.009, η2partial = 0.25).In the full sample (n = 47), perceptual comparison speed correlated significantly with gray matter volumes in the anterior and medial temporal lobes (TFCE, FWE p < 0.01). @*Conclusion@#Along with generalized deficit across multiple cognitive domains, selectively greater impairment of perceptual comparison speed appears to characterize chronic schizophrenia. This pattern might indicate an accelerated or premature cognitive aging. Anterior-medial temporal gray matter volumes especially of the left hemisphere might underlie the impairment noted in this domain in schizophrenia.

RESUMO

ABSTRACT Osteoporosis, a disease classically attributed to postmenopausal women, is underappreciated, underdiagnosed, and undertreated in men. However, it is not uncommon for osteoporotic fractures to occur in men. About 40% of fractures occur in men with an incidence that has increased over the years. After a first fracture, the risk of a subsequent episode, as well as the risk of death, is higher in the male than in the female population. Despite these facts, only 10% of men with osteoporosis receive adequate treatment. Up to half of the cases of male osteoporosis have a secondary cause, the most common being hypogonadism, excessive alcohol consumption, and chronic use of glucocorticoids. The International Society for Clinical Densitometry (ISCD) recommends using the female database for the diagnosis of osteoporosis by DXA (T-score ≤ −2.5 in men over 50 years old). In addition, osteoporosis can also be diagnosed independently of the BMD if a fragility fracture is present, or if there is a high risk of fractures by FRAX. Treatment is similar to postmenopausal osteoporosis, because the data regarding changes in bone density track closely to those in women. Data concerning fracture risk reduction are not as certain because the clinical trials have included fewer subjects for shorter period of time. In men with symptomatic hypogonadism, testosterone replacement, if indicated, can improve BMD.

RESUMO

ABSTRACT Denosumab (DMAb) is a human monoclonal antibody used as an antiresorptive drug in the treatment of osteoporosis. Approval at a dosage of 60 mg every 6 months was based on the results of the randomized, placebo-controlled trial (FREEDOM). The design of this 3-year study included an extension for up to 10 years. Those who were randomized to DMAb continued on drug, while those who were randomized to placebo transitioned to DMAb. The 10-year experience with DMAb provides data on efficacy of drug in terms of reduced fractures and continued increases in bone mineral density (BMD). The 10-year experience with denosumab also provides information about rare complications associated with the use of DMAb, such as osteonecrosis of the jaw (ONJ), and atypical femoral fractures (AFF). This experience provided new insights into the reversibility of effects upon discontinuation without follow-on therapy with another agent. This review focuses upon prolonged treatment with DMAb, with regard to beneficial effects on fracture reduction and safety. Additionally, its use in patients with impaired renal function, compare its results with those of bisphosphonates (BPs), the occurrence/frequency of complications, in addition to the use of different tools, from imaging techniques to histological findings, to evaluate its effects on bone tissue.

RESUMO

ABSTRACT Objective: The fibroblast growth factor 23 (FGF23) has been related to biological aging, but data in elderly individuals are scant. We determined the profile of serum FGF23 levels in a population of very-old individuals and studied their correlations with parameters of bone metabolism and health markers, as functional performance. Materials and methods: This cross-sectional study was performed on 182 community dwellers aged ≥ 80 years. Serum levels of FGF23, PTH, calcium, albumin, phosphorus, creatinine, bone markers, and bone mineral density data were analyzed. Physical performance was evaluated with the stationary march (Step), Flamingo, and functional reach tests, along with questionnaires to assess falls and fractures in the previous year, energy expenditure (MET), and the Charlson index (CI). Physical activity was evaluated with the International Physical Activity Questionnaire (IPAQ). Results: Most participants (75%) had FGF23 levels between 30-120 RU/mL (range: 6.0-3,170.0 RU/mL). FGF23 levels correlated with estimated glomerular filtration rate (eGFR; r = -0.335; p = 0.001) and PTH (r = 0.318; p < 0.0001). Individuals with FGF23 in the highest tertile had more falls in the previous year (p = 0.032), worse performance in the Flamingo (p = 0.009) and Step (p < 0.001) tests, worse CI (p = 0.009) and a trend toward sedentary lifestyle (p = 0.056). On multiple regression, FGF23 tertiles remained significant, independently of eGFR, for falls in the previous year, performance in the Flamingo and stationary march tests, lean mass index, and IPAQ classification. Conclusion: In a population of very elderly individuals, FGF23 levels were inversely associated with neuromuscular and functional performances. Higher concentrations were related to more falls, lower muscle strength and aerobic capacity, and poorer balance, regardless of renal function, suggesting a potentially deleterious role of high FGF23 concentrations in musculoskeletal health.

RESUMO

Circulating concentrations of thyrotropin (TSH) and thyroxine (T4) are tightly regulated. Each individual has setpoints for TSH and free T4 which are genetically determined, and subject to environmental and epigenetic influence. Pituitary-thyroid axis setpoints are probably established in utero, with maturation of thyroid function continuing until late gestation. From neonatal life (characterized by a surge of TSH and T4 secretion) through childhood and adolescence (when free triiodothyronine levels are higher than in adults), thyroid function tests display complex, dynamic patterns which are sexually dimorphic. In later life, TSH increases with age in healthy older adults without an accompanying fall in free T4, indicating alteration in TSH setpoint. In view of this, and evidence that mild subclinical hypothyroidism in older people has no health impact, a strong case can be made for implementation of age-related TSH reference ranges in adults, as is routine in children.

RESUMO

Vertebral artery injuries account for approximately 19% of cerebral vascular injuries and are typically managed conservatively. However, some patients require operative intervention to gain control of an active hemorrhage, either via surgical ligation or endovascular intervention. We present a case of iatrogenic vertebral artery injury occurring during cervical spine surgery which was treated emergently with a self-expanding covered stent. A 58-year-old male presented for cervical traction, C5 and C6 corpectomy, and possible C4 to T2 posterior fusion following a motor vehicle accident. Intraoperatively, following drilling the C5 endplate, copious bleeding was observed from injury to the right vertebral artery resulting in pseudoaneurysm formation. The patient was loaded with ticagrelor and a self-expanding covered stent was placed via a transfemoral approach, resulting in obliteration of the pseudoaneurysm prior to completion of his cervical spine surgery. Emergent self-expanding covered stent placement for iatrogenic vertebral artery injury in the setting of an intraoperative injury is a safe and effective option. Ticagrelor is a viable alternative to traditional dual antiplatelet therapy for preventing thromboembolic complications in this urgent setting.

RESUMO

Background/Aims@#Nonalcoholic fatty liver disease (NAFLD) encompasses a range of diseases from nonalcoholic fatty liver (NAFL) to nonalcoholic steatohepatitis (NASH) and has been linked to cardiovascular disease and sub-clinical cardiac remodeling. This paper presents a retrospective study of biopsy-proven NAFL and NASH to examine the differences in subclinical cardiac remodeling. @*Methods@#Patients were recruited from an institutional repository of patients with liver-biopsy-confirmed NAFLD. Patients with a transthoracic echocardiogram (TTE) within 12 months of the liver biopsy were included. The parameters of the diastolic dysfunction were reviewed for the differences between NAFL and NASH as well as between the stages and grades of NASH. @*Results@#Thirty-three patients were included in the study, 17 with NAFL and 16 with NASH. The NASH patients were more likely to have lower platelets, higher AST, higher ALT, and higher rates of type 2 diabetes mellitus, coronary artery disease, and hypertension than the NAFL patients. The E/e’ ratio on transthoracic echocardiogram was significantly higher in NASH compared to NAFL, advanced-stage NASH compared to early stage, and high-grade NASH compared to low-grade. The E/e’ ratio was also significantly higher in NASH than NAFL in patients without diabetes mellitus. The presence of diastolic dysfunction trended toward significance. The other markers of diastolic dysfunction were similar. Logistic regression revealed a statistical association with E/e' and NASH. @*Conclusions@#NASH patients had evidence of a higher E/e’ ratio than NAFL, and there was a trend towards a significant diastolic dysfunction. Patients with NASH compared to NAFL should be closely monitored for signs and symptoms of cardiac dysfunction.

RESUMO

@#<p style="text-align: justify;"><strong>Background.</strong> Low levels of high-density lipoprotein cholesterol (HDL-c) is a well-recognized risk factor in the development of cardiovascular diseases. Associated gene variants for low HDL-c have already been demonstrated in various populations. Such associations have yet to be established among Filipinos who reportedly have a much higher prevalence of low HDL-c levels compared to other races.</p><p style="text-align: justify;"><strong>Objective.</strong> To determine the association of selected genetic variants and clinical factors with low HDL-c phenotype in Filipinos.</p><p style="text-align: justify;"><strong>Methods.</strong> An age- and sex-matched case-control study was conducted among adult Filipino participants with serum HDL-c concentration less than 35 mg/dL (n=61) and those with HDL-c levels of more than 40 mg/dL (n=116). Genotyping was done using DNA obtained from blood samples. Candidate variants were correlated with the low HDL-c phenotype using chi-squared test and conditional logistic regression analysis.</p><p style="text-align: justify;"><strong>Results.</strong> Twelve single nucleotide polymorphisms (SNPs) were associated with low HDL-c phenotype among Filipinos with univariate regression analysis. The variant rs1260326 of glucokinase regulator (GCKR) (CT genotype: adjusted OR=5.17; p-value=0.007; TT genotype: adjusted OR=6.28; p-value=0.027) remained associated with low HDL-c phenotype, together with hypertension and elevated body mass index, after multiple regression analysis.</p><p style="text-align: justify;"><strong>Conclusion.</strong> The variant rs1260326 near GCKR is associated with low HDL-c phenotype among Filipinos.

RESUMO

Objective@#To investigate the distribution and aerosolized particle counts generated during mastoidectomy, we utilized low-cost and locally available material and developed a plastic tent creating a barrier between the health care workers (HCW) and patient. @*Methods@#The barrier tent is a clear plastic bag attached to the microscope lens. The tent is draped and tucked underneath the patient’s head and upper torso with surgeon’s arms also passed underneath and secured with clamps. We demonstrated the area of greater contamination by spread of droplet particles and bone dust after drilling using fluorescent dye. Particle counts inside and outside the barrier was determined and then comparison with and without the tent after drilling of cadaveric temporal bone were also done. @*Results@#The area with highest concentration of contamination (“hot zone”) was noted opposite the surgeon’s hand drill which is dependent on the operator’s handedness. Other hot zones noted were opposite the operator and on the operator’s side. Particle determination of aerosol size 0.3 and 2.5µm inside the barrier tent were at peak levels after bone drilling procedure. Then a significant drop of particle counts was noted at 2 minutes after drilling was stopped with flattening observed at 8 minutes. @*Conclusion@#Our experimental results suggest that the improvised barrier tent can be effective in mitigating aerosols generated during mastoid surgery and may serve as an added protection for the operating room team.
