  • β-Blocker Doses and Heart Rate in Patients with Heart Failure: Results
           from the National Norwegian Heart Failure Registry

    • Abstract: Background: Use of β-blockers and titration to the highest tolerated dose are highly recommended by the European Society of Cardiology (ESC) guidelines for treatment of chronic heart failure (HF) with a reduced ejection fraction (HFrEF), but little attention has been paid to the achieved heart rate (HR) during this treatment. Objectives: The aim of the present study was to examine the achieved HR in relation to the use of β-blockers in these patients. Methods: All of the patients (n = 2,689) in the National Norwegian Heart Failure Registry as part of the Norwegian Cardiovascular Disease Registry with a sinus rhythm and left ventricular ejection fraction (LVEF) #x3c;40% at stable follow-up visiting specialised hospital outpatient HF clinics in Norway were included. The β-blocker doses were calculated as a percent of the target dose according to ESC HF guidelines. Differences between baseline variables according to the achieved HR were analysed by the Student’s t test for continuous variables and Pearson’s χ2 test for categorical variables. Linear regression was used to determine the predictors of HR ≥70 beats/min (bpm) in the multivariate analysis. Results: One third of the patients had a resting HR ≥70 bpm. Of the patients with an HR ≥70 bpm, 72.3% used less than the target dose of β-blocker; they were younger and had a higher NYHA class, more diabetes mellitus and chronic obstructive pulmonary disease (COPD), and higher N-terminal pro-B type natriuretic peptide (NT-proBNP) levels and estimated glomerular filtration rates compared to the patients with an HR #x3c;70 bpm. The 1-year mortality was 3.1, 3.7, 5.8, and 9.1% among the patients with an HR #x3c;70, 70–79, 80–89, and #x3e;89 bpm, respectively. Only 2 patients used ivabradine. Conclusions: In patients with HFrEF and sinus rhythm, an HR ≥70 bpm was associated with worse clinical variables and outcomes. A high proportion of the patients who had an HR ≥70 bpm was not treated with or/did not tolerate the target dose of a β-blocker, although the β-blocker dose was higher than in patients with an HR #x3c;70 bpm. This may suggest that increased efforts should be made to further increase the β-blocker dose, and treatment with ivabradine could be considered among patients with an HR ≥70 bpm.

  • Association Study of MTHFR Polymorphisms with Nonarteritic Anterior
           Ischemic Optic Neuropathy in a Spanish Population

    • Abstract: Introduction: Nonarteritic anterior ischemic optic neuropathy (NAION), painless loss of central and/or peripheral vision, is a multifactorial disease caused by insufficient blood flow through the posterior ciliary arteries to the optic nerve head. Mutations in the methylenetetrahydrofolate reductase (MTHFR) gene, triggering hyperhomocysteinemia as a consequence of a decreased activity of the codified enzyme, have been considered to be among the risk factors of NAION. Objective: The main aim was to study the association of the most common MTHFR genetic polymorphisms C677T and A1298C with NAION in a Spanish population. Methods: In this case-control study, the association of the most common MTHFR polymorphisms was investigated in 94 unrelated native Spanish patients diagnosed with NAION and 204 healthy controls. Two single nucleotide polymorphisms located in the MTHFR gene, C677T (rs1801133) and A1298C (rs1801131), were analyzed by DNA sequencing and TaqMan assays. Results: The allelic and genotypic frequencies of the MTHFR variants obtained in the NAION group were not significantly different when compared with the control group. A higher frequency of the C677T/A1298C genotype, codifying the nonmutated MTHFR form, was obtained in control subjects (11.27%) compared to NAION patients (4.26%), suggesting a protective effect of the wild-type protein, although this result was not conclusive considering the obtained confidence interval (CI) (95% CI: 0.13–1.06). Study of additional clinical factors including hypertension, diabetes mellitus, and dyslipidemia showed no association with a higher risk of NAION. Conversely, the clinical history of heart or cerebrovascular diseases was significantly higher in NAION patients compared to controls. Over the world, risk variants of the MTHFR gene are highly frequent, excluding African black populations, indicating a racial influence. Conclusions: The MTHFR variants did not significantly increase the risk of suffering from NAION. However, considering that individuals with at least one of the risk variants have the MTHFR enzyme with decreased activity, it cannot be ruled out that these mutations are relevant for the development of NAION in a subgroup of the population with other specific characteristics. These may include high plasma levels of homocysteine along with nutritional deficiencies including low folate or vitamin B12 and the combination of systemic and local risk factors.

  • Outcomes of Infants with Mild Hypoxic Ischemic Encephalopathy Who Did Not
           Receive Therapeutic Hypothermia

    • Abstract: Introduction: Accurately diagnosing and treating infants with mild forms of hypoxic ischemic encephalopathy (HIE) is important, as the majority of neonates with signs and symptoms of HIE after birth do not meet clinical criteria for moderate or severe disease. Emerging evidence, however, suggests that infants with mild HIE (mHIE) have an increased risk for neurodevelopmental impairment (NDI). Methods: This retrospective descriptive study examined all inborn infants ≥35 week’s gestational age at a single, level III neonatal intensive care unit (NICU) in California between January 1, 2012, and December 31, 2015. International Classification of Diseases codes were used as a proxy to identify neonates with mHIE but who did not receive therapeutic hypothermia (TH). Short- and long-term neurodevelopmental outcomes were documented, including abnormal (1) brain magnetic resonance imaging within 10 days of birth suggestive of HIE, (2) electroencephalogram with electrographic seizures, (3) neurologic discharge examination, or (4) NDI following NICU discharge. Results: Over the 4-year study period, 25 infants met inclusion criteria. Eight of 25 (32%) infants demonstrated neurologic impairment, defined by an abnormality in at least one of the four categories. The remaining 17 infants were without documented evidence for adverse outcomes. Conclusion: Our results indicate that children with mHIE are at significant risk for neurologic injury and may benefit from more aggressive interventions. Further prospective studies should be completed to determine the efficacy of TH in this specific patient population.

  • Bifidobacterium Supplementation of Colostrum and Breast Milk Enhances
           Weight Gain and Metabolic Responses Associated with Microbiota
           Establishment in Very-Preterm Infants

    • Abstract: Background: Postnatal growth restriction in very-preterm infants (VPIs) may have long-lasting effects. Recent evidence suggests that developmental problems in VPIs are related to abnormalities in intestinal microbial communities. Objective: To investigate the effect on growth outcomes in VPIs of supplementation with Bifidobacterium along with mother’s colostrum and breast milk. Methods: A randomized controlled study was performed on 35 VPIs, born between 24 and 31 weeks of gestation with birth weights #x3c;1,500 g. The patients received either daily Bifidobacterium breve supplementation (Bifid group) or vehicle supplement only (placebo group). Parenteral nutrition was initiated with glucose, amino acids, and fatty acids for all of the infants soon after birth. Each infant received their own mother’s colostrum within 24 h of birth, and breast milk on subsequent days. Fecal bacteria, organic acids, pH, bile acids, and plasma fatty acids were analyzed. Results: Seventeen infants were allocated to the Bifid group and 18 to the placebo group; the birth weights and gestational ages did not differ significantly between the two groups. Compared to the placebo group, the Bifid group showed significantly greater and earlier weight gain by 8 weeks; significantly higher total fecal bacterial counts, including bifidobacteria; higher levels of total fecal short-chain fatty acids and nominally (but not significantly) higher concentrations of plasma n–3 fatty acids; and lower levels of total fecal bile acid. Conclusions: Bifidobacterial supplementation of maternal colostrum and breast milk yielded the establishment of a beneficial microbiota profile, leading to favorable metabolic responses that appeared to provide improved growth in VPIs.

  • Teaching Helping Babies Breathe via Telehealth: A New Application in Rural

    • Abstract: Background: Helping Babies Breathe (HBB) is a neonatal resuscitation curriculum that teaches life-saving interventions utilized in the first minutes after birth, reducing morbidity and mortality. Traditionally, it requires in-person facilitators for didactic and hands-on training. Objectives: The aim of this study was to offer HBB to nurses and nursing students in Guatemala, with the lead facilitator presenting concepts via telehealth and in-person facilitators providing hands-on demonstration. Methods: Learners completed pre- and post-tests that included the standard HBB knowledge check, as well as an assessment of the course teaching model. Learners also completed the standard Objective Structured Clinical Evaluations (OSCEs). Results: Eighteen learners were included in the analysis. All but one learner (94%) passed the course, and the average percent improvement from the pre- to post-test was 12%. All learners achieved passing scores on the OSCEs. Learners responded positively to questions regarding the technology, connection with the instructor, and ability to ask questions. Ninety-four percent of the learners agreed with the statement “this lecture was as good via telehealth as in person.” A cost analysis demonstrated approximately USD 3,979.00 in savings using telehealth compared to a standard in-person course. Conclusions: The telehealth model was successful in delivering course material to the learners and was well received. This model represents a cost-effective way to improve access to HBB. This study may not be generalizable to other populations, and the ability to use telehealth requires reliable internet connectivity, which may not be available in all settings. Further study and expansion of this pilot are needed to assess success in other settings.

  • Primary Pulmonary MALT Lymphoma: A Case Report and Literature Review

    • Abstract: Background: Primary pulmonary MALT (mucosa-associated lymphoid tissue) lymphoma is a rare entity that imposes a rigorous and demanding diagnostic work-up. Case Report: We present the case of a 74-year-old female non-smoker with a previous healed pulmonary tuberculosis and a history of arterial hypertension and fibromyalgia. She was referred to the pulmonology clinic to investigate a right inferior lobe (RIL) rounded pulmonary opacity (4 × 3.4 cm) identified on a previous thoracic CT scan performed for unrelated reasons. The remaining findings were non-specific and included small calcified mediastinal and hepatic adenopathies and multiple calcified hepatosplenic foci. The 18F-FDG-PET revealed high 18F-FDG uptake at the RIL lesion (SUV 4.7), suspicious for neoplastic involvement. Flexible bronchoscopy and CT-guided transthoracic needle biopsy were non-diagnostic and she was submitted to videothoracoscopy with surgical biopsy. The histological and immunohistochemical examination of the clear margin RIL segmentectomy were in keeping with a MALT lymphoma. Conclusion: The authors present this case to highlight this rare entity, which is particularly challenging to diagnose due to non-specific multimodality imaging features, frequently implying more invasive procedures and surgical biopsy for a final diagnosis.

  • Migration of an Ingested Fish Bone to the Submandibular Gland: A Case
           Report and Literature Review

    • Abstract: Background: Fish bone is one of the most common foreign bodies that gets lodged in the upper digestive tract, often located in the tonsil, epiglottis, pear-shaped fossa, and esophagus, where it may be easily located on routine inspection and removed. The forcible swallowing of food such as rice balls after ingesting fish bones by mistake may lead to the migration of the fish bone from the pharynx, throat, or esophagus to the surrounding tissues. Migration most commonly occurs to the soft tissues of the neck, even to the thyroid gland, but migration to the submandibular gland has rarely been reported. Conclusions: Foreign body ingestion may cause a series of complications and endanger a patient’s life. Cases require high awareness and attentiveness on the part of the first physician to diagnose and manage the condition, and appropriate health education should be imparted to the patient.

  • A Randomized Controlled Trial Comparing a Mapleson Circuit with Nasal
           Trumpet to Standard Oxygen Supplementation during EBUS Bronchoscopy under
           Monitored Anesthesia Care

    • Abstract: Background: Endobronchial ultrasound (EBUS) procedures tend to be longer than routine bronchoscopies. Increased duration and sedative dosing put patients at increased risk for ­hypoxic events. Objective: To determine whether oxygen supplementation via a nasal trumpet connected to a Mapleson B circuit (NTM) was effective in decreasing hypoxic events when compared with the standard of care, oxygen supplementation with a nasal cannula (NC). Methods: Patients referred for EBUS-guided transbronchial needle aspiration with monitored anesthesia care (MAC) were randomized 1:1 to NTM or to NC. Hypoxia-related procedural interruptions, the primary endpoint of the study, were documented for all patients. Patients in the NC group who had refractory desaturations were allowed to cross over to the NTM group. Secondary endpoints included: number of crossovers from NC to NTM, sedative dosing, total procedure times, whether procedure goals were achieved, complications apart from hypoxia, patient discharge status. Results: Fifty-two patients were randomized to NC and 48 to NTM. Baseline characteristics were comparable. The NC group had significantly more interruptions than did the NTM group (p #x3c; 0.001). Procedure duration was also significantly (p #x3c; 0.03) shorter for the NTM group. Fourteen patients were crossed over from NC to NTM because of hypoxia. Thirteen out of the 14 completed the procedure with no interruptions. All procedures were successfully completed, and all goals were achieved. All patients returned to baseline status prior to discharge. Three minor complications of epistaxis occurred. Conclusion: For patients undergoing EBUS with MAC, oxygen supplementation with NTM significantly decreased the incidence of hypoxic events when compared with NC. NTM may also be of value for other subsets of patients who are at increased risk for desaturation when undergoing bronchoscopy.

  • Ultrasound-Guided Cervical Lymph Node Sampling Performed by Respiratory

    • Abstract: Background: A variety of disease processes investigated by respiratory physicians can lead to cervical lymphadenopathy. Ultrasound (US) has revolutionised respiratory investigations, and neck ultrasound (NUS) is increasingly recognised as an additional important skill for respiratory physicians. Objectives: We aimed to assess the feasibility of NUS performed by respiratory physicians in the workup of patients with mediastinal lymphadenopathy. Methods: This is a single-centre retrospective cohort study. All patients that underwent US-guided cervical lymph node sampling were included. The diagnostic yield is reported, and specimen adequacy is compared for respiratory physicians and radiologists. Results: Over 5 years, 106 patients underwent NUS-guided lymph node sampling by respiratory physicians compared to 35 cases performed by radiologists. There was no significant difference in the adequacy of sampling between the two groups (respiratory physicians 91.5% [95% CI 84.5–96%] compared to 82.9% [95% CI 66.4–93.4%] for radiologists [p = 0.2]). In the respiratory physician group, a diagnosis was achieved based on lymph node sampling in 89 cases (84%). Neck lymph node sampling was the only procedure performed to obtain tissue in 48 cases (45.3%). Conclusion: NUS and sampling performed by respiratory physicians are feasible and associated with an adequacy rate comparable to that of radiologists. It can reduce the number of invasive procedures performed in a selected group of patients. Guidelines for training and competency assessment are required.
