Clinical Manifestations of Subjects With the Non-Specific Pulmonary Function Test Pattern

Introduction: Non-specific pattern (NSP) is a subgroup of preserved ratio impaired spirometry (PRISm) that requires a normal total lung capacity measurement. NSP has been historically classified as being an obstructive lung disease pattern. There has been heightened interest and investigation into PRISm recently as it has been associated with an increased likelihood of developing chronic obstructive pulmonary disease (COPD). Given the inherent challenges of understanding the clinical significance of the NSP, the aim of this study was to further explore the clinical characteristics of patients with this pulmonary function test pattern. Material and methods: We identified 111 and 79 subjects using pre-bronchodilator (pre-BD) and post-bronchodilator (post-BD) values, respectively, that met criteria for NSP. The outpatient medical records were retrospectively reviewed for associated diagnoses that were then clustered into ‘obstructive’ or ‘non-obstructive’ groups based on the treating physician's primary pulmonary clinical diagnosis. Results: Within this NSP cohort, cough, wheezing and sputum production were documented more frequently in those with an obstructive lung disease diagnosis. Whether identified using pre-BD or post-BD spirometric values, those with NSP and a positive BD response were more likely to carry an obstructive lung disease diagnosis. Conclusion: Approximately one third of patients with NSP in this study were not given an obstructive lung disease diagnosis by their clinician, which supports the classification of NSP as not an exclusively obstructive lung disease pattern. However, the presence of supporting clinical symptoms, such as cough with sputum production and wheeze, and/or a positive BD response on PFT, support a diagnosis of obstruction in patients with NSP. Resumen: Introducción: El patrón inespecífico constituye un subgrupo de alteraciones de la espirometría con conservación de la relación (PRISm, siglas en inglés) que precisa de una medición de la capacidad pulmonar total normal; históricamente se ha clasificado como un patrón de neumopatía obstructiva. En épocas recientes se ha intensificado el interés en las PRISm y su investigación, ya que se ha asociado a un aumento de la probabilidad de aparición de una enfermedad pulmonar obstructiva crónica (EPOC). Dadas las dificultades inherentes que conlleva interpretar la importancia clínica del patrón inespecífico, el objetivo de este estudio consistió en explorar con más detalle las características clínicas de los pacientes con dicho patrón en las pruebas de la función pulmonar. Material y métodos: Se identificaron 111 y 79 sujetos empleando valores prebroncodilatador y posbroncodilatador, respectivamente, que cumplieron los criterios de patrón inespecífico. Se revisaron retrospectivamente las historias clínicas ambulatorias para detectar diagnósticos asociados que después se agregaron en grupos «obstructivos» o «no obstructivos» en función del diagnóstico clínico pulmonar primario del médico. Resultados: En esta cohorte de pacientes con patrones inespecíficos, se documentó una mayor incidencia de tos, sibilancias y producción de esputo entre los que tenían un diagnóstico de neumopatía obstructiva. Los pacientes con patrón inespecífico y una respuesta positiva al broncodilatador, que hubiesen sido identificados con valores pre o posbroncodilatador, tenían más probabilidades de haber recibido un diagnóstico de neumopatía obstructiva. Conclusión: Aproximadamente un tercio de los pacientes con patrón inespecífico de este estudio no habían recibido un diagnóstico de neumopatía obstructiva, dato que avala no clasificar los patrones inespecíficos exclusivamente en las neumopatías obstructivas. Sin embargo, la presencia de síntomas clínicos indicativos, como tos productiva y sibilancias, o una respuesta positiva al broncodilatador en las pruebas de la función pulmonar, sustenta un diagnóstico de obstrucción en los pacientes con patrón inespecífico

Kidney Recovery and Death in Critically Ill Patients With COVID-19-Associated Acute Kidney Injury Treated With Dialysis: The STOP-COVID Cohort Study.

Rationale & objectiveAcute kidney injury treated with kidney replacement therapy (AKI-KRT) occurs frequently in critically ill patients with coronavirus disease 2019 (COVID-19). We examined the clinical factors that determine kidney recovery in this population.Study designMulticenter cohort study.Setting & participants4,221 adults not receiving KRT who were admitted to intensive care units at 68 US hospitals with COVID-19 from March 1 to June 22, 2020 (the "ICU cohort"). Among these, 876 developed AKI-KRT after admission to the ICU (the "AKI-KRT subcohort").ExposureThe ICU cohort was analyzed using AKI severity as the exposure. For the AKI-KRT subcohort, exposures included demographics, comorbidities, initial mode of KRT, and markers of illness severity at the time of KRT initiation.OutcomeThe outcome for the ICU cohort was estimated glomerular filtration rate (eGFR) at hospital discharge. A 3-level outcome (death, kidney nonrecovery, and kidney recovery at discharge) was analyzed for the AKI-KRT subcohort.Analytical approachThe ICU cohort was characterized using descriptive analyses. The AKI-KRT subcohort was characterized with both descriptive analyses and multinomial logistic regression to assess factors associated with kidney nonrecovery while accounting for death.ResultsAmong a total of 4,221 patients in the ICU cohort, 2,361 (56%) developed AKI, including 876 (21%) who received KRT. More severe AKI was associated with higher mortality. Among survivors, more severe AKI was associated with an increased rate of kidney nonrecovery and lower kidney function at discharge. Among the 876 patients with AKI-KRT, 588 (67%) died, 95 (11%) had kidney nonrecovery, and 193 (22%) had kidney recovery by the time of discharge. The odds of kidney nonrecovery was greater for lower baseline eGFR, with ORs of 2.09 (95% CI, 1.09-4.04), 4.27 (95% CI, 1.99-9.17), and 8.69 (95% CI, 3.07-24.55) for baseline eGFR 31-60, 16-30, ≤15 mL/min/1.73 m2, respectively, compared with eGFR > 60 mL/min/1.73 m2. Oliguria at the time of KRT initiation was also associated with nonrecovery (ORs of 2.10 [95% CI, 1.14-3.88] and 4.02 [95% CI, 1.72-9.39] for patients with 50-499 and <50 mL/d of urine, respectively, compared to ≥500 mL/d of urine).LimitationsLater recovery events may not have been captured due to lack of postdischarge follow-up.ConclusionsLower baseline eGFR and reduced urine output at the time of KRT initiation are each strongly and independently associated with kidney nonrecovery among critically ill patients with COVID-19

Emergent fishery of the catostylid jellyfish Crambionella orsini along the southern coast of India

Sporadic and seasonal landings of jellyfishes along the southern coast of India have been under investigation since 2018. The catostylid jellyfish Crambionella orsini is the only species that contributes to a fishery in this region. In the October to January months, a seasonal fishery exists along the Kanyakumari, Thiruvananthapuram and Neendakara coast, with catches being made variously by gillnetters, single day trawlers, multi-day trawlers and shore seines. An unprecedented 44 day fishery on the Neendakara coast from December 2020 to January 2021 was investigated in depth, with estimated landings of 453.16 metric tonnes landed at Sakthikulangara and Neendakara Fisheries Harbours in Kollam District, Kerala. Economic efficiency of the fishery from Sakthikulangara Fisheries Harbour was estimated as 44.76 gross value added as percentage of gross revenue and net operating income of `1313 per fishing trip with average earning to a crew member being `510 per trip. The oral arms of C. orsini is the only part of the jellyfish that are traded and exported, mainly to China and South east Asian countries after salt curing. Emergence of this augmentative fishery has come as a boon to fishers combating the regressive environment of the Covid-19 period. Promotion of this fishery with increased processing and export facilities and investigations into value added products from the resource is recommended

Transcriptome characterization of matched primary breast and brain metastatic tumors to detect novel actionable targets.

Background: Breast cancer brain metastases (BrMs) are defined by complex adaptations to both adjuvant treatment regimens and the brain microenvironment. Consequences of these alterations remain poorly understood, as does their potential for clinical targeting. We utilized genome-wide molecular profiling to identify therapeutic targets acquired in metastatic disease.Methods: Gene expression profiling of 21 patient-matched primary breast tumors and their associated brain metastases was performed by TrueSeq RNA-sequencing to determine clinically actionable BrM target genes. Identified targets were functionally validated using small molecule inhibitors in a cohort of resected BrM ex vivo explants (n = 4) and in a patient-derived xenograft (PDX) model of BrM. All statistical tests were two-sided.Results: Considerable shifts in breast cancer cell-specific gene expression profiles were observed (1314 genes upregulated in BrM; 1702 genes downregulated in BrM; DESeq; fold change > 1.5, Padj Conclusions: RNA-seq profiling of longitudinally collected specimens uncovered recurrent gene expression acquisitions in metastatic tumors, distinct from matched primary tumors. Critically, we identify aberrations in key oncogenic pathways and provide functional evidence for their suitability as therapeutic targets. Altogether, this study establishes recurrent, acquired vulnerabilities in BrM that warrant immediate clinical investigation and suggests paired specimen expression profiling as a compelling and underutilized strategy to identify targetable dependencies in advanced cancers.</p
