Sensitivity to specific common odors correlates with symptoms of depression or anxiety, new research shows. A study of more than 400 participants showed that symptoms of anxiety were associated with heightened awareness of floral scents or kitchen smells, while depression was linked to increased awareness of social odors including "good" and "bad" smells of other people. "The assessment of meta-cognitive abilities may be a useful tool in assessing depressive, anxiety, and social anxiety symptoms," study investigator Cinzia Cecchetto, PhD student, postdoctoral researcher, Department of General Psychology, University of Padua, Italy, told Medscape Medical News. The findings were published online April 13 in the Journal of Affective Disorders.

Can Sensitivity to Common Smells Sniff Out Depression, Anxiety?
'Healthy' Plant-Based Diet Linked to Reduced Stroke Risk
Maintaining a healthy plant-based diet is associated with a lower risk for both total stroke and ischemic stroke, results from a study of three large cohorts suggest. A plant-based diet was not associated with risk for hemorrhagic stroke, however, and the data also showed no association between a fully vegetarian diet and total stroke risk, the researchers report. Most of the previous studies of this question defined a plant-based diet as a vegetarian diet, without differentiating the quality of plant foods, they note.
RE: New Trial Data Show Hair Growth in More Alopecia Areata Patients
@srijit The researchers pooled data from both clinical trials, with a combined enrollment of 1200, for the 52-week results presented at the meeting. The placebo group stopped at 36 weeks, and these patients were randomly reassigned to either the 4-mg or 2-mg once-daily baricitinib treatment groups.
Pathophysiology of Angioid Streaks
In 1889, Doyne first described angioid streaks in a patient with retinal hemorrhages secondary to trauma. Angioid streaks, also known as Knapp striae, are irregular jagged dehiscences in the mineralized, degenerated, brittle Bruch membrane that typically form alongside force lines exerted by intrinsic and extrinsic ocular muscles that radiate in a centrifugal pattern emanating from the optic disc. Knapp named them angioid streaks because of their resemblance to blood vessels
Early Egg Introduction Does Not Lower Allergy Risk
Regular egg consumption starting at 4 to 6 months of age does not change the risk for egg allergy at 1 year of age or older, compared with delayed introduction of eggs, the authors of a new study report. However, some of the findings, which come from the Starting Time of Egg Protein (STEP) randomized, double-blind trial, do hint at a possible benefit of early egg introduction, they point out.
RE: Pathophysiology of Chlamydia (Chlamydial Genitourinary Infections)?
@rohit-m The pathophysiologic mechanisms of chlamydial infection are poorly understood at best. Chlamydia infects columnar epithelial cells, which places the adolescent female at particular risk because of the presence of the squamocolumnar junction on the ectocervix until early adulthood. The initial response of epithelial cells to infection is a neutrophilic infiltration, followed by lymphocytes, macrophages, plasma cells, and eosinophilic invasion. The release of cytokines and interferons by the infected epithelial cell initializes this inflammatory cascade.
Infection with chlamydial organisms invokes a humoral cell response, resulting in secretory immunoglobulin A (IgA) and circulatory immunoglobulin M (IgM) and immunoglobulin G (IgG) antibodies and a cellular immune response. A 40-kd major outer membrane protein (MOMP) and 10- and 60-kd chlamydial heat-shock proteins (cHSPs) have been implicated in the immunopathologic response, but further studies are needed to provide a better understanding of these cell-mediated immune responses
Prognosis of Drug-Induced Lupus Erythematosus ??
Drug-induced lupus erythematosus (DILE) is a variant of lupus erythematosus that resolves within days to months after withdrawal of the culprit drug in a patient with no underlying immune system dysfunction. DILE can arise months to years after exposure to drugs prescribed to treat various medical conditions (eg, antihypertensives, antibiotics, anticonvulsants). The most common drugs that cause DILE are hydralazine, procainamide, quinidine, isoniazid, diltiazem, targeted immunotherapy, and minocycline. What is the prognosis of this disease?
Does voting ink cause itching?
Does voting ink cause itching? I am worried about this. I learnt that a 30-year-old male presented to the emergency with complaints of pain, swelling, burning sensation and black staining of fingertips of both hands. Please elaborate on this.
A person is suffering from chronic asthma, what should be the dietary restriction?
Hello, A person is suffering from chronic asthma, what should be the dietary restriction? some research suggests that certain foods can support lung function, boost the immune system, and reduce asthma symptoms. Others, however, may worsen symptoms or increase the chance of asthma developing. Please recommend what to eat and what to avoid.
RE: How to treat acne?
@debangshu If you've tried over-the-counter (nonprescription) acne products for several weeks and they haven't helped, ask your doctor about prescription-strength medications. A dermatologist can help you:
Control your acne
Avoid scarring or other damage to your skin
Make scars less noticeable
Acne medications work by reducing oil production and swelling or by treating bacterial infection. With most prescription acne drugs, you may not see results for four to eight weeks. It can take many months or years for your acne to clear up completely. The treatment regimen your doctor recommends depends on your age, the type and severity of your acne, and what you are willing to commit to. For example, you may need to wash and apply medications to the affected skin twice a day for several weeks. Topical medications and drugs you take by mouth (oral medication) are often used in combination. Treatment options for pregnant women are limited due to the risk of side effects.
Cervical spine cord injury management options?
A 21-year-old, fit and healthy football player was tackled from behind while running with the ball. He lost his balance and landed on his head. This resulted in a burst fracture dislocation of C5/C6 associated with immediate onset of complete tetraplegia. He was originally admitted to the local hospital. In the A&E department, management of his airway and respiratory compromise arising from his level of cord transection necessitated intubation and ventilation support. He had surgical stabilization of the cervical spine with bone grafting 5 days after injury. As attempted extubation after surgery failed, he required formal tracheostomy 10 days later. Postoperatively he developed chest infection and a Grade 3 pressure sore in the sacral region.
