Anesthetic effects changeable in habitual drinkers: Mechanistic drug interactions with neuro-active indoleamine–aldehyde condensation products associated with alcoholic beverage consumption

Perioperative Concerns in the Patient with History of Alcohol Use

Alcohol use is common in patients presenting for surgery and can result in significant physiologic changes and postoperative complications. Anesthesia providers must be aware of the potential risks associated with alcohol consumption and take steps to minimize them. Perioperative management includes assessing patients for alcohol use, providing alcohol cessation interventions, adjusting the anesthetic plan according to the patient's alcohol use history, providing appropriate pain management strategies, and closely monitoring patients during and after surgery for signs of alcohol withdrawal.

Patient-reported outcome measures following surgeries in implant dentistry and associated factors: a cross-sectional study

OBJECTIVES

We aimed to evaluate the patient-reported outcome measures (PROMs) of dental implant surgeries and analyse the associated indicators.

DESIGN

A cross-sectional study design was used.

SETTING

Department of Oral Implantology, Hospital of Stomatology, Wuhan University (May 2020-April 2021).

PARTICIPANTS

Participants with missing teeth in need of implant-supported rehabilitation.

INTERVENTIONS

Dental implant placement and/or bone augmentation procedures.

PRIMARY AND SECONDARY OUTCOME MEASURES

The primary outcome was discomfort on postoperative day 1, measured using a numerical rating scale (NRS). Secondary outcomes included pain and anxiety during surgery; discomfort on postoperative days 3, 7 and 14; and post-surgical complications.

RESULTS

A total of 366 participants were included, of which 288 (78.7%) and 328 (89.7%) reported no to mild pain and anxiety (NRS 0-3) during surgery, respectively. The proportion of patients reporting discomfort decreased from postoperative day 1 (57.7%) to day 3 (36.1%) and day 7 (17.5%). The most frequent postoperative adverse events were pain and swelling. Patient-related factors (age, sex, smoking, alcohol consumption, history of periodontitis, and pain and anxiety during surgery) and surgery-related factors (type and extent of surgical procedure) were analysed. The factors associated with the severity of discomfort after surgery included alcohol consumption, pain perception during surgery, bone augmentation procedures and age (p<0.05). Similarly, the factors associated with the duration of discomfort included alcohol consumption, pain perception during surgery and age (p<0.05).

CONCLUSIONS

PROMs related to dental implant surgeries can be predicted using certain risk indicators. Alcohol consumption, pain during surgery and age were associated with discomfort following dental implant surgery.

β-Carbolines as potential anticancer agents

β-Carbolines are indole alkaloids having a tricyclic pyrido[3,4-b]indole ring in their structure. Since the isolation of first β-carboline from Peganum harmala in 1841, the isolation and synthesis of various β-carboline derivatives surged in the following centuries. β-Carboline derivatives due to their widespread availability from natural sources, structural flexibility, quick reactivity and interaction with varied anticancer targets such as DNA (intercalation, groove binding, etc.), enzymes (GPX4, topoisomerases, kinases, etc.) and proteins (tubulin, ABCG2/BRCP1, etc.) have established themselves as promising lead compounds for the synthesis of various anticancer active agents. The current review covers the synthesis and isolation, anticancer activity, mechanism of action and SAR of various β-carboline containing molecules, its derivatives and congeners.
