Effect of time-dependent ibuprofen administration on the post operatory after impacted third molar extraction: a cross-over randomized controlled trial.

PURPOSE: To evaluate time-dependent administration of ibuprofen in a lower third molar extraction model. METHODS: Eleven patients requiring bilateral surgical removal of lower third molars were recruited and randomized into a blinded crossover randomized controlled trial. For 3 days after surgery, the control group was prescribed ibuprofen 400 mg every 8 h. On the other hand, the experimental group received also ibuprofen 400 mg at breakfast and lunch, replacing the dinner intake with a placebo. Pain measurements (Visual Analog Scale from 0 to 10) were recorded at baseline, 24, 48, and 72 h p

Antidepressant chronotherapeutics normalizes prefrontal 1H-MRS glutamate in bipolar depression.

BACKGROUND: Dysfunctional glutamatergic neurotransmission has been proposed both, as a biological underpinning of mood disorder and as a target for rapid-acting antidepressant treatments. Total sleep deprivation and light therapy (TSD + LT) can prompt antidepressant response in drug-resistant bipolar depression. Here we explored the effects of TSD + LT on dorsolateral prefrontal cortex (DLPFC) glutamate and/or glutamine+glutamate (Glx) levels. METHODS: We studied single voxel 1H-MRS measures of DLPFC Glu and Glx levels of 48 healthy participants and 55 inpatients with a major depressive episo

Can chronopharmacology improve the therapeutic management of neurological diseases?

The importance of circadian rhythm dysfunctions in the pathophysiology of neurological diseases has been highlighted recently. Chronopharmacology principles imply that tailoring the timing of treatments to the circadian rhythm of individual patients could optimize therapeutic management. According to these principles, chronopharmacology takes into account the individual differences in patients' clocks, the rhythmic changes in the organism sensitivity to therapeutic and side effects of drugs, and the predictable time variations of disease. This review examines the current literature on chronoph

A brief history of circadian time in the heart.

This review tracks the discovery of circadian biology in cardiovascular science, starting with early clinical observations of daily changes in heart rate, blood pressure, and cardiovascular events. These patterns suggested that time of day matters, but it was not until the past two decades that the mechanisms and knowledge translation of these rhythms were uncovered. We describe the heart's intrinsic circadian properties and importantly how this leads to regulation of cardiac gene and protein expression, neuroendocrine and vascular rhythms, metabolism, cellular electrophysiology, and cell sign

Sleep, circadian rhythms, chronobiology, and neural synchrony: Integrative mechanisms in brain function, health, and disease.

Sleep and circadian rhythms are crucial for regulating metabolism, cognitive function, and nightly brain repair. Chronobiology studies these … as timekeepers, and thalamocortical circuits as mediators of neural synchrony. It also details how chronotherapy, light treatments targeting the circadian system, and AI-based sleep pattern analysis act on these mechanisms to benefit brain health. By clarifying how chronobiology and neuroscience intersect at the level of specific biological mechanisms, this re …

Качество сна и сон у взрослых с множественной миеломой. Возможно ли лечение мелатонина?

Нездоровые сны оказывают значительное воздействие на качество жизни больных раком, однако они по-прежнему плохо характеризуются множественной миеломой (ММ). Цель этого исследования состояла в том, чтобы охарактеризовать профили сна у пациентов из числа ММ и оценить терапевтический потенциал внешнего мелатонина. Мы оценили 46 Пациенты ММ и 64 :: возрастной контроль с использованием индекса качества сна Питтсбурга (PSQI) и шкалы сна Epworth (ESS). Данные показали значительно более низкое качество сна у пациентов с ОМ по сравнению с контрольными показателями (глобальная PSQI: U = 1126; p = 0.034)

Role of Chronobiology as a Transdisciplinary Field of Research: Its Applications in Treating Mood Disorders.

Chronobiology is a field that studies the effects of time on biological systems. Periodicity is of particular interest. The master biological clock in the suprachiasmatic nucleus controls daily rhythms of core body temperature, rest-activity cycle, physiological and behavioral functions, psychomotor functions and mood in humans. The clock genes are involved in the generation of the circadian rhythms and the biological clock is synchronized to solar day by direct photic inputs. Various circadian rhythm abnormalities have been demonstrated in mood disorders such as unipolar depression, bipolar d

Circadian rhythms and medical diseases: does it matter when drugs are taken?

BACKGROUND: Chronobiology is devoted to the study of biological rhythms. It is possible that a given medication may be therapeutic and safe when administered at some time, but subtherapeutic or poorly tolerated at another. METHODS: We focused on some classes of drugs, widely used by the internists, performing a PubMed search with the single drugs associated with the MeSH terms "Chronotherapy", "Circadian rhythm", and "Chronobiology, phenomena". Among the studies found, we considered only those provided with discrete numerosity or clearly stated methodological characteristics. RESULTS: The re…

Case study of circadian rhythm sleep disorder following haloperidol treatment: reversal by risperidone and melatonin.

A patient with Gilles de la Tourette syndrome treated with haloperidol, ingested once daily after awakening from sleep, exhibited an irregular sleep-wake pattern with a free-running component of approximately 48 h. Transfer to risperidone, ingested once daily after awakening from sleep, was beneficial resulting in a sleep-wake cycle more synchronized at the appropriate phase to the external zeitgebers, and fewer nocturnal disturbances. The circadian sleep-wake schedule was fully synchronized when the patient had been subsequently treated with melatonin at 21:00h, before intended nocturnal slee

Influences of biological rhythms on the effects of psychotropic drugs.

The efficacy of psychotropic drugs varies depending on the time of administration. This phenomenon is observed with antipsychotics, antidepressants, mood stabilizers, benzodiazepines, barbiturates, and psychostimulants. The presence or absence of this phenomenon and the rhythm phase in the efficacy of each drug varies depending on the drug, dose, parameter measured, animal species, and strain. A recent study demonstrating circannual changes in the phases of circadian rhythm of drug efficacy suggests that discrepancies between studies may be considerably explained by the presence of a circannua

Unraveling the interplay of circadian rhythm and sleep deprivation on mood: A Real-World Study on first-year physicians.

The interplay between circadian rhythms, time awake, and mood remains poorly understood in the real-world. Individuals in high-stress occupations with irregular schedules or nighttime shifts are particularly vulnerable to depression and other mood disorders. Advances in wearable technology have provided the opportunity to study these interactions outside of a controlled laboratory environment. Here, we examine the effects of circadian rhythms and time awake on mood in first-year physicians using wearables. Continuous heart rate, step count, sleep data, and daily mood scores were collected from

Crosstalk Between Aging, Circadian Rhythm, and Melatonin.

Circadian rhythms (CRs) are 24-hour periodic oscillations governed by an endogenous circadian pacemaker located in the suprachiasmatic nucleus (SCN), which organizes the physiology and behavior of organisms. Circadian rhythm disruption (CRD) is also indicative of the aging process. In mammals, melatonin is primarily synthesized in the pineal gland and participates in a variety of multifaceted intracellular signaling networks and has been shown to synchronize CRs. Endogenous melatonin synthesis and its release tend to decrease progressively with advancing age. Older individuals experience frequ
