Considering Needle Phobia among Adult Patients During Mass COVID-19 Vaccinations.

As mass vaccination is underway to combat the COVID-19 pandemic and achieve herd immunity, healthcare professionals need to recognize the fear and phobia of needles among their patients. Approximately 11.5 to 66 million U.S. adults may suffer from this condition. This population often avoids seeking medical care including vaccinations. The exact number of people suffering from this phobia is unknown, and the potential years of life lost in the American health care system cannot be estimated accurately. The resistance to vaccinations among this population may delay achieving herd immunity to end this current pandemic. An overview of needle phobia, vaccinations, and current treatments are explored. The use of telemedicine could prove critical for reaching this population as well as those who are hesitant about vaccinations. Providing education to healthcare providers to identify and manage these patients during the pandemic is necessary.

Impact of antidepressant use on gastric bypass surgery patients' weight loss and health-related quality-of-life outcomes.

BACKGROUND: Psychological factors may be predictive of post-surgical adjustment and successful outcomes in obesity-surgery populations. OBJECTIVE: The authors compared post-gastric bypass surgery (GBS) outcomes of patients being given active psychotropic treatment for depression, with those of patients without treatment or identifiable need for treatment at enrollment. METHOD: Outcome measures included weight and repeated administration of the Medical Outcome Survey Short Form-36 (SF-36). RESULTS: There was no impact of antidepressant treatment on GBS patients' weight loss or SF-36 outcomes. CONCLUSION: Therefore, patients with actively treated depression should be expected to have GBS outcomes equivalent to those of patients without identifiable psychiatric illness or treatment.

Plasma progesterone concentration depends on sampling site in pigs.

The objective of this study was to examine a possible difference in progesterone concentrations between the systemic venous blood and the caudal vena cava in early pregnant gilts. Nineteen crossbred pregnant gilts were offered three different regimens of feeding to examine influence of feeding on the secretion pattern of progesterone. The groups were high (H-H), low (L-L) and low-high (L-H) receiving 3.6, 1.8 and 1.8/3.6 kg/day, respectively. Catheters were placed in a jugular vein and the caudal vena cava (to sample ovarian secretion) on day 19 of pregnancy. Two consecutive samples taken at 30-min intervals were collected four times a day for 5 days (days 20-24). In addition, three gilts were simultaneously sampled from both catheters at 30-min intervals for 12 h on day 22. Progesterone concentration was significantly lower in the jugular vein compared with the caudal vena cava in all three feeding groups (P<0.001). An indication of episodic pattern of progesterone production occurred in plasma collected from the caudal vena cava, but not from the jugular vein. Dietary intake did not cause a profound effect on plasma progesterone concentrations during days 20-24 of gestation. It seemed that ovarian progesterone was released into the vena cava in an episodic pattern and there were implications that these episodes were temporally associated with LH pulses.

Menangle and Nipah virus infections of pigs.

Viruses belonging to the family Paramyxoviridae generally have not been recognized as a significant cause of disease in pigs until recently. Between 1997 and 1999, there were large outbreaks of disease in pigs in Australia and Malaysia due to infection with viruses that have been shown to be new members of the Paramyxoviridae family. This article reviews current knowledge of Menangle and Nipah virus infections in pigs, the only major species of domestic animals to experience serious disease after infection with these viruses.
