Coronavirus Disease 2019 (COVID-19) Reinfection Rates in Malawi: A Possible Tool to Guide Vaccine Prioritisation and Immunisation Policies.

As the fight against the COVID-19 pandemic continues, reports indicate that the global vaccination rate is still far below the target. Understanding the levels of reinfection may help refocus and inform policymakers on vaccination. This retrospective study in Malawi included individuals and patients who tested for COVID-19 infections via reverse transcriptase polymerase chain reaction (rt-PCR) from the data at the Public Health Institute of Malawi (PHIM).

Awareness of HIV/AIDS prevention and acceptance of HIV testing among residents in Likoma Island, northern Malawi.

To evaluate the awareness of HIV/AIDS prevention education, and the acceptance of HIV testing among residents on Likoma Island, Malawi, a cross-sectional, population-based study of 579 residents aged > or =15 years from seven villages on Likoma Island was conducted during July and August 2007. Most of the subjects studied could correctly answer questions about their awareness of AIDS and knowledge of the ways to reduce HIV transmission. Moreover, the proportion of respondents (65.

The use of hospital medical records for child injury surveillance in northern Malawi.

Our study evaluates the usefulness and the limitations of using the medical records of a central referral hospital to develop a child injury surveillance system in northern Malawi. The most prevalent types of injury were falls (29.6%), road traffic injuries (22.

The application of infrared thermography in the assessment of patients with coccygodynia before and after manual therapy combined with diathermy.

Objective: This study examines the potential usefulness of a novel thermal imaging technique in the assessment of local physiologic responses before and after conservative therapies for coccygodynia.

Methods: Patients with coccygodynia were selected on the basis of detailed history taking, clinical examination, and dynamic series radiography. They underwent therapeutic modalities consisting of 6 to 8 sessions of manual medicine treatments (massage of the levators followed by Maigne's manipulative technique) and external physiotherapy (short-wave diathermy) 3 times a week for 8 weeks.

Total intravenous anesthesia for repair of congenitral diaphragmatic hernia: a case report.

Congenital diaphragmatic hernia is a cardiopulmonary anomaly that causes severe respiratory disorder. Traditionally, inhalational anesthetics with mechanical hyperventilation, opioids, and muscle relaxants are used in anesthesia for repair surgery. In this case, we used total intravenous anesthesia combined with high-frequency oscillatory ventilation and inhaled nitric oxide for surgical repair of the diaphragm.

Urgosedin inhibits hypotension, hypoglycemia, and pro-inflammatory mediators induced by lipopolysaccharide.

Urgosedin is a newly synthesized compound especially with serotonergic and alpha-adrenergic blocking actions. In rat isolated thoracic aorta, urgosedin competitively antagonized norepinephrine-, clonidine-, and serotonin-induced vasocontractions in a concentration-dependent manner. In radioligand binding experiments, urgosedin had significant binding affinities on alpha1/alpha2, 5-HT1A, 5-HT1B and 5-HT2A receptors.

Punctate midline myelotomy for intractable visceral pain caused by hepatobiliary or pancreatic cancer.

The purpose of this study was to demonstrate the existence of a newly recognized midline posterior column pathway that mediates the perception of visceral pain resulting from hepatobiliary or pancreatic cancer. A punctate midline myelotomy (PMM) of T(3) level was performed in 6 patients who experienced severe visceral pain caused by hepatobiliary or pancreatic cancer. Preoperatively, the pain was refractory to strong opioids.

Spinal process landmark as a predicting factor for difficult epidural block: a prospective study in Taiwanese patients.

Although epidural anesthesia is a common practice in neuraxial blockade, difficult access to the epidural space is a frequent problem in operating theaters. We designed this study of epidural blocks to determine if the spinal landmark grading system is valuable in predicting a difficult epidural block. Before the epidural block, we collected the following data: demographics, body habitus (normal, thin, obese, pregnant), spinal anatomy (normal, deformed), spinal level (lumbar, thoracic), and spinal landmark grade (grade 1: spinous processes visible; grade 2: spinous processes not seen but easily palpated; grade 3: spinous processes not seen and not palpated but the interval between them is palpated as a low landmark under the thumb; grade 4: other).

Ropivacane 0.1 % with or without fentanyl for epidural postoperative analgesia: a randomized, double-blind comparison.

Epidural analgesia is often considered optimal postoperative analgesia for certain surgical procedures. Ropivacaine is a new local anesthetic that is less toxic than its homologue, bupivacaine. Epidural infusions usually comprise a local anesthetic, an opioid, or a combination of the two to improve analgesic efficacy and reduce unwanted side effects.

Epidural ropivacaine for postoperative analgesia in Taiwanese patients.

Background: Ropivacaine is the latest long-acting amide local anesthetic. As it is less cardiovasculotoxic and neurotoxic than bupivacaine it is an attractive anesthetic agent used in clinical anesthesia and postoperative analgesia. This study was undertaken to seek for a suitable dosage of ropivacaine in postoperative analgesia for Taiwanese patients whose average physicality is not entirely compatible with the pharmacopeially recommended dosage for western people.
