The documented publications provide a basis for assessing the researcher’s alignment with an international research recognition program in medicine.

Abstract

Daniel Alfaiate’s documented research profile is focused on clinical and physiological aspects of sleep and respiratory medicine. His publications examine topics including psychotropic medication and sleep architecture, obstructive sleep apnea and hematological parameters, wakefulness electroencephalography in patients with obstructive sleep apnea, and body posture among patients receiving non-invasive ventilation. These studies collectively address clinically relevant questions involving sleep physiology, respiratory disorders, diagnostic assessment, and treatment-related factors. The available record reports three documents, 31 citations, and an h-index of 2, providing bibliometric context for evaluating the researcher’s scholarly activity.[1] [2]

Keywords

Daniel Alfaiate; sleep medicine; obstructive sleep apnea; sleep architecture; polysomnography; electroencephalography; non-invasive ventilation; respiratory medicine; psychotropic medication; clinical research; medical research; research hypothesis; Portugal.

Introduction

Sleep medicine integrates clinical observation, physiological measurement, diagnostic technologies, and therapeutic evaluation to investigate disorders affecting sleep and breathing. Obstructive sleep apnea is characterized by recurrent episodes of upper-airway obstruction during sleep and can be studied through clinical assessment and objective sleep-related measurements. Research involving polysomnography, electroencephalography, respiratory parameters, and related physiological indicators can therefore contribute to a more detailed understanding of patient characteristics and treatment considerations.[1] [2] [3] [4]

Research Profile

Daniel Alfaiate is affiliated with the Instituto Politécnico de Castelo Branco in Portugal. The supplied bibliometric profile identifies Scopus Author ID 58158006300 and reports three documents, 31 citations, and an h-index of 2. These values represent the supplied research-profile information and should be interpreted in relation to the indexing date and database coverage.

Research Contributions

The research record contains several contributions to the study of sleep and respiratory disorders. A recent article in the European Journal of Pharmacology investigates the class-specific and cumulative effects of psychotropic medication on sleep architecture using polysomnographic retrospective data. This study addresses the relationship between medication exposure and objectively measured sleep characteristics, providing a clinical pharmacology perspective on sleep physiology. [1]

Research Impact

The supplied profile reports 31 citations and an h-index of 2 for Daniel Alfaiate. Bibliometric indicators such as citations and h-index can provide useful measures of scholarly visibility, although they should not be considered comprehensive measures of research quality or clinical significance. Citation counts can vary among databases and change over time.

Award Suitability

Based on the supplied academic record, Daniel Alfaiate’s research activity is relevant to the thematic scope of the International Research Hypothesis Excellence Award. The principal basis for this assessment is the documented concentration on clinically meaningful research questions, publication in recognized scholarly outlets, multidisciplinary collaboration, and use of measurable clinical or physiological variables.

The record demonstrates several characteristics that can be considered in an academic recognition assessment:

  • Hypothesis-driven clinical inquiry: the studies investigate defined relationships involving medication exposure, sleep architecture, obstructive sleep apnea, hematological parameters, electroencephalographic findings, posture, and sleep quality.
  • Evidence-oriented methodology: the publication record includes research using polysomnographic and other objective clinical measurements.

Conclusion

Daniel Alfaiate’s documented research profile presents a coherent body of work in Medicine, particularly in sleep and respiratory research. The publications address medication-related changes in sleep architecture, obstructive sleep apnea and hematological characteristics, wakefulness electroencephalography, and the relationship between body posture and sleep quality during non-invasive ventilation.
