Exposure to war is linked to negative mental health outcomes. Self-compassion and emotional intelligence may foster post-war adjustment processes differently depending on the time since the event happened. This study examines post-traumatic stress symptoms (PTSS) in civilians exposed to the 2020 Nagorno-Karabakh war shortly after and 6 months post-conflict, while investigating self-compassion and emotional intelligence's protective role.

Accurate epidemiological models are necessary for governments, organizations, and individuals to respond appropriately to the ongoing novel coronavirus pandemic. One informative metric epidemiological models provide is the basic reproduction number ([Formula: see text]), which can describe if the infected population is growing ([Formula: see text]) or shrinking ([Formula: see text]). We introduce a novel algorithm that incorporates the susceptible-infected-recovered-dead model (SIRD model) with the long short-term memory (LSTM) neural network that allows for real-time forecasting and time-dependent parameter estimates, including the contact rate, [Formula: see text], and deceased rate, [Formula: see text].

 From April 2009 to December 2016, 661 consecutive patients undergoing sinus surgery completed a quality of life (QOL) questionnaire (SNOT-22) preoperatively and at 3, 6, and 12 months postoperatively.  (1) To evaluate the long-term efficacy of sinus surgery using QOL instruments. (2) To determine the optimal evaluation time for surgical efficacy.

Objective: Chronic rhinosinusitis (CRS) has long been associated with vocal dysfunction. However, studies quantifying the presence of voice dysfunction in CRS patients or the effects of functional endoscopic sinus surgery (FESS) are sparse. The goal of this study was to determine the voice-related quality of life in patients undergoing FESS for CRS using the validated Voice Related Quality of Life Survey (VRQL).

Background: Chronic rhinosinusitis (CRS) has long been a suspected risk factor for Eustachian tube dysfunction (ETD). However, there have been few studies quantifying the presence of ETD in CRS patients. We sought to determine the prevalence of ETD symptoms in patients undergoing functional endoscopic sinus surgery (FESS) for CRS using the validated 7-item Eustachian Tube Dysfunction Questionnaire (ETDQ-7) and to correlate the ETDQ-7 scores with scores of CRS symptom severity based on the 22-item Sino-Nasal Outcome Test (SNOT-22).

Possibilities for the recovery of non-ferrous and precious metals from Kapan polymetallic mine tailings (Armenia) were studied. The aim of this paper was to study the possibilities of bioleaching of samples of concentrated tailings by the natural microbial consortium of drainage water. The extent of extraction of metals from the samples of concentrated tailings by natural microbial consortium reached 41-55% and 53-73% for copper and zinc, respectively.
