No evidence for differential gene expression in major depressive disorder PBMCs, but robust evidence of elevated biological ageing.

Transl Psychiatry 2021 Jul 22;11(1):404. Epub 2021 Jul 22.

Institute of Infection, Immunity & Inflammation, University of Glasgow, Glasgow, UK.

The increasingly compelling data supporting the involvement of immunobiological mechanisms in Major Depressive Disorder (MDD) might provide some explanation forthe variance in this heterogeneous condition. Peripheral blood measures of cytokines and chemokines constitute the bulk of evidence, with consistent meta-analytic data implicating raised proinflammatory cytokines such as IL6, IL1β and TNF. Among the potential mechanisms linking immunobiological changes to affective neurobiology is the accelerated biological ageing seen in MDD, particularly via the senescence associated secretory phenotype (SASP).

Sarcopenia: What Is the Origin of This Aging-Induced Disorder?

Front Genet 2021 2;12:688526. Epub 2021 Jul 2.

Division of Clinical Physiology, Department of Laboratory Medicine, Karolinska Institutet, Stockholm, Sweden.

We here review the loss of muscle function and mass (sarcopenia) in the framework of human healthspan and lifespan, and mechanisms involved in aging. The rapidly changing composition of the human population will impact the incidence and the prevalence of aging-induced disorders such as sarcopenia and, henceforth, efforts to narrow the gap between healthspan and lifespan should have top priority. There are substantial knowledge gaps in our understanding of aging. Read More

[Biofeed back therapy and Cytoflavin in the system of medical support of the training process of elderly hockey players.]

Adv Gerontol 2021 ;34(2):306-310

I.I.Mechnikov North-Western State Medical University, 41 Kirochnaya str., St. Petersburg 191015, Russian Federation.

One of the ways to improve the condition of the elderly body is the method of auto-training with biofeedback, as a means of correcting deviations in the functioning of the regulatory apparatus, as well as improving antioxidant protection and eliminating the effects of oxidative stress using Cytoflavin therapy. These methods seem to be a simple and effective means of correcting negative changes in the FS of elderly hockey players after a training cycle and ensuring the possibility of a more complete recovery of their body. The difference in the points of application made it possible to combine the intake of Cytoflavin and biofeedback training into a single complex correctional and restorative technique. Read More

["Long-haul COVID": An opportunity to address the complexity of post-infectious functional syndromes].

Rev Med Interne 2021 Jul 9;42(7):492-497. Epub 2021 Jun 9.

Service de médecine interne, hôpital Nord, CHU de Saint-Étienne, 42055 Saint-Étienne cedex 2, France.

In this work, we address the issue of prolonged symptoms following an infection by SARS-CoV-2, labeled "long COVID". This clinically unspecific syndrome must be put in perspective with the post-infectious syndromes known for a long time but ultimately poorly understood and little studied, qualified, for lack of convincing arguments for a unambiguous pathophysiology and better terms, as functional somatic syndromes. The clinical implications for clinical care ("holistic" work-up and care of patients), for research (need for truly "bio-psycho-social" investigations), and the social implications of "long COVID" (social construction of the syndrome through the experiences of patients exposed on social networks, inequalities in the face of the disease and its socioeconomic consequences) are considered.

Leg Med (Tokyo) 2021 Sep 25;52:101910. Epub 2021 May 25.

School of Forensic Medicine, Southern Medical University, Guangzhou, 510515 Guangdong, China; School of Basic Medicine and Life Science, Hainan Medical University, Haikou, 571199 Hainan, China. Electronic address:

Traditional autopsy and microscopic examination of pathological sections are the "gold standard" for the cause of death diagnosis. However, in some special cases, such as the deaths caused by bacterial infections, pathological sections are not always sufficient to provide convincing evidences for determining the causes of death. In recent years, with the development of Next Generation Sequencing (NGS), clinical medicine has already introduced it into the diagnosis of difficult diseases, which is rare in forensic pathological diagnoses.

Changes in arterial blood pressure characteristics following an extrasystolic beat or a fast 50 ml fluid challenge do not predict fluid responsiveness during cardiac surgery.

J Clin Monit Comput 2021 May 26. Epub 2021 May 26.

Department of Anaesthesia and Intensive Care, Aarhus University Hospital, Pale Juul-Jensens Boulevard 99, building C319, 8200, Aarhus N, Denmark.

Prediction of fluid responsiveness is essential in perioperative goal directed therapy, but dynamic tests of fluid responsiveness are not applicable during open-chest surgery. We hypothesised that two methods could predict fluid responsiveness during cardiac surgery based on their ability to alter preload and thereby induce changes in arterial blood pressure characteristics: (1) the change caused by extrasystolic beats and (2) the change caused by a fast infusion of 50 ml crystalloid (micro-fluid challenge). Arterial blood pressure and electrocardiogram waveforms were collected during surgical preparation of the left internal mammary artery in patients undergoing coronary artery bypass surgery.

Adv Exp Med Biol 2021 ;1187:601-612

Yom Breast Clinic, Seoul, South Korea.

Phyllodes tumors of breast (PTB) have been known to an uncommon and particular disease to handle owing to diagnostic ambiguity and unpredictable clinical outcome. Malignant phyllodes tumors (MPT) are diagnosed when there are marked stromal hypercellularity, atypia, increased mitoses of ≥10/10 HPFs, permeative tumor borders, and stromal overgrowth. The presence of a malignant heterologous element (MHE) places the tumor into the malignant category regardless of other histological features. Read More
