Objectives: Grain storage facility entrapments continue to be of concern in the agricultural industry, with nearly 1,500 documented incidents recorded over the last 45 years. Previous research studies have shown that attempting to extricate a full-size pulling test dummy from a grain mass requires a substantial amount of tensile or pull force - e.g.

Article Synopsis
  • The study compares the effectiveness of two biomaterials—xenografts (deproteinized bovine bone) and nanohydroxyapatite—for sinus floor elevation in patients with vertically deficient posterior maxillary alveolar ridges.
  • In the trial involving 24 patients, both biomaterials led to good bone consolidation, but the difference in mean bone height and quality between groups was not statistically significant.
  • The researchers concluded that both materials performed similarly in terms of bone regeneration, suggesting the need for larger studies with longer follow-ups to better assess outcomes.

Valproic acid holds a prominent position as the primary therapeutic option for epilepsy cases. The utilization of antiepileptic agents like valproic acid has been linked to disturbances in sleep architecture. Although scant, there exists a subset of studies that allude to the potential manifestation of sleep apnea as an adverse effect of valproic acid administration.

Highlights: Approximately ten cases were documented annually over the 44-year period; 48% were in the last decade and 28% were in the last three years, primarily due to more aggressive surveillance and on-line access to incident reports. A total of 389 incidents involving 459 individuals were documented, of which 59% were fatal; >85% of the victims were male, with an average age of 37. 49 rescue incidents involved a total of 119 secondary victims, indicating that approximately 26% of the victims were secondary victims, including first responders.

HIGHLIGHTS A total of 133 cases were documented in a seven-state region, with Iowa reporting 43% of the cases and asphyxiations accounting for 42% of all cases. Most victims were male (>79%) with an average age of 38 years. The overall fatality rate was 57%, and 16% of the victims were under the age of 21.

Background: Assessment of microalbuminuria and hypoalbuminemia can be used as a good tool for the prediction of the ICU outcome in critically ill patients.

Purpose: To evaluate and compare the prognostic significance of microalbuminuria (albumin creatinine ratio (ACR)) and serum albumin level done on admission and after twenty-four hours for the critically ill patients. .

Manure storage, handling, and transport facilities and equipment have been associated with life threatening hazards on many livestock farms. These hazards have been documented in prior research as including 1) exposure to toxic manure gases or lack of adequate oxygen in enclosed structures, which can be fatal to both humans and livestock; 2) below and above ground liquid manure storage structures that have the potential risk for drowning and falling; and 3) mechanical hazards associated with manure handling and transport equipment, including entanglement, road collisions, runover, and equipment failure. Over the past 40 years, Purdue University's Agricultural Safety and Health Program (PUASHP) has collected, documented, and maintained data regarding agricultural-related injuries and fatalities associated with agricultural confined spaces in the United States.

Background: Direct implantation of metallic drug-eluting stents is recommended for lesions with high thrombotic burden; however, this can't be applied to bioresorbable scaffold for which adequate lesion preparation is recommended.

Aim: We aimed at assessing the feasibility and safety of direct scaffold implantation based only on angiographic assessment in patients presented with non-ST segment elevation acute coronary syndrome.

Methods: The study was a retrospective two-centre study conducted over patients diagnosed with NSTE-ACS presented to cardiology department at Juan Ramon Hospital, Spain and critical care department, Cairo University in the period between February 2016 to May 2017.

As part of ongoing surveillance of fatalities and injuries involving agricultural confined spaces by Purdue University's Agricultural Safety and Health Program, nearly 300 cases involving manure storage, handling, and transport equipment and facilities have been documented over the past 30 years. With the exception of a summary of 77 fatalities published by Beaver and Field, these cases have not been previously analysed or published due to a lack of resources and the limitations of the Purdue Agricultural Confined Spaces Incident Database (PACSID) which was designed primarily for analysis of grain-related cases. These limitations included differences in terminology used to code case information in the PACSID and dissimilar causative and contributing factors.

No previous studies have been found that document the level of use or validate the effectiveness of safety harnesses and lifelines in the prevention of or extrication from grain entrapments or engulfments. This article addresses that void via analysis of the data contained in the Purdue Agricultural Confined Space Incident Database. A total of 1,147 cases involving entrapments or engulfments in grain masses were mined for terms that might indicate the use of a safety harness, lifeline, fall restraint system, rope, or outside observer.

Purpose The aim of the study was to determine the impact of telephone follow-up calls on satisfaction in oncology patients after hospital discharge. Method A randomized controlled study, in which patients were randomized into two groups: The experimental group with the telephone follow-up (TFU) calls (intervention) and the control group (no intervention). The telephone follow-up call was conducted within 72 h after discharge.
