How safe is Autheem therapy for young Saudi infants? A question worth asking.

Background: In Saudi Arabia, a traditional therapy for a folk labeled problem known as "Autheem - " is often offered to infants. The procedure involves manipulating an infant's soft palate to alleviate pain associated with infant colic and poor feeding. However, concerns remain about this procedure's impact on infant health and its potential to transmit infections. This study focused on perceptions that Saudi mothers hold about Autheem therapy. Methods: A descriptive, cross-sectional, community-based study was conducted via an online platform to reach Saudi mothers in the Riyadh region of Saudi Arabia. Results: Five hundred and thirty-six Saudi mothers participated; half were older than 30 years of age. Despite a high rate of college degree attainment, the majority of mothers relied on their elders as a source of information (88.4%). Autheem was viewed to be a stand-alone disease by 86.5% of respondents; 71.4% believed it could not be treated with modern medicine. Most infants were under six months of age when they received Autheem therapy (72%). Roughly 13% of mothers found that their infant had a fever after the therapy; we found an association between Autheem therapy and viral illnesses. About 13% of mothers altered their child's vaccination schedule after Autheem therapy. Conclusion: Older mothers have more positive attitudes towards and stronger beliefs in Autheem therapy than younger mothers. The therapy's strong association with viral illnesses and its negative impact on vaccination schedules are major public health concerns.

A Review of Quartz Crystal Microbalance for Chemical and Biological Sensing Applications.

Humans are fundamentally interested in monitoring and understanding interactions that occur in and around our bodies. Biological interactions within the body determine our physical condition and can be used to improve medical treatments and develop new drugs. Daily life involves contact with numerous chemicals, ranging from household elements, naturally occurring scents from common plants and animals, and industrial agents. Many chemicals cause adverse health and environmental effects and require regulation to prevent pollution. Chemical detection is critically important for food and environmental quality control efforts, medical diagnostics, and detection of explosives. Thus, sensitive devices are needed for detecting and discriminating chemical and biological samples. Compared to other sensing devices, the Quartz Crystal Microbalance (QCM) is well-established and has been considered and sufficiently sensitive for detecting molecules, chemicals, polymers, and biological assemblies. Due to its simplicity and low cost, the QCM sensor has potential applications in analytical chemistry, surface chemistry, biochemistry, environmental science, and other disciplines. QCM detection measures resonate frequency changes generated by the quartz crystal sensor when covered with a thin film or liquid. The quartz crystal is sandwiched between two metal (typically gold) electrodes. Functionalizing the electrode's surface further enhances frequency change detection through to interactions between the sensor and the targeted material. These sensors are sensitive to high frequencies and can recognize ultrasmall masses. This review will cover advancements in QCM sensor technologies, highlighting in-sensor and real-time analysis. QCM-based sensor function is dictated by the coating material. We present various high-sensitivity coating techniques that use this novel sensor design. Then, we briefly review available measurement parameters and technological interventions that will inform future QCM research. Lastly, we examine QCM's theory and application to enhance our understanding of relevant electrical components and concepts.

Ceftazidime-avibactam use for the treatment of OXA-48- and/or New Delhi metallo-ß-lactamase-producing Enterobacterales in cancer patients: a retrospective observational study.

BACKGROUND: Infection is the second-leading cause of death among cancer patients, but there have been few studies on the effectiveness of novel antimicrobial agents to treat carbapenem-resistant Enterobacterales in cancer patients. OBJECTIVE: Evaluate the mortality and clinical outcomes of ceftazi-dime-avibactam for OXA-48- and/or New Delhi metallo-ß-lactamase (NDM)-producing Enterobacterales infection in cancer patients. DESIGN: Retrospective observational cohort study. SETTING: Tertiary academic medical center in Riyadh, Saudi Arabia. SUBJECTS AND METHODS: This study included patients who had cancer and received ceftazidime-avibactam for at least 72 hours for infections caused by OXA-48- and/or NDM-producing Enterobacterales. We excluded patients who died within 72 hours of treatment, patients with polymicrobial infections, and patients who did not receive appropriate antimicrobial therapy. MAIN OUTCOMES AND MEASURES: Primary outcomes were 30-day mortality and hospital mortality. Secondary outcomes included clinical cure, relapse, and reinfection. SAMPLE SIZE: 32 cancer patients. RESULTS: The 30-day mortality among all patients was 15/32 (47%), clinical cure was achieved in 19/32 (59%) of the patients, and the relapse and reinfection rates were 2/19 (10.5%) and 4/17 (23.5%), respectively. CONCLUSION: This is the largest study to evaluate clinical outcomes associated with infections caused by OXA-48- and/or NDM-producing Enterobacterales in cancer patients. The mortality rate remains high; however, ceftazidime-avibactam is an encouraging alternative for treating severe infections in cancer patients. LIMITATIONS: Small sample size and single center.

Microcytic Anemia Hiding Vitamin B12 Deficiency Anemia.

Vitamin B12 is an essential water-soluble vitamin that mediates multiple coenzymes needed for cell synthesis, mainly the red blood cells. Its deficiency is characterized by megaloblastic anemia and neuropsychiatric symptoms. Macrocytosis is the classical picture seen usually, but having microcytosis is unlikely. We report a case series of three cousins with vitamin B12 deficiency who presented with microcytosis.

Cluster Headache and Associated Risk Factors: A Systemic Review and Meta-Analysis.

Cluster headache (CH) has always been associated with several risk factors, including hereditary, environmental, and lifestyle habits. This study focuses on important risk factors, including family history, smoking, alcohol consumption, male predominance, and head trauma associated with CH. The present study aimed at investigating the available literature on cluster headaches and evaluating their associated risk factors. A systematic data search was designed, and scientific data were collected from renowned databases, including PubMed, Cochrane, Embase, Cumulative Index of Nursing and Allied Health Literature (CINAHL), and Google Scholar. Thirty-two studies were selected to execute a systemic review, and 26 studies, consisting of 6,065 CH patients, qualified for a meta-analysis. Statistical analyses were conducted by using MedCalc, version 16.8.4; (MedCalc Software, Ostend, Belgium; http://www.medcalc.org) and Rapidminer statistical software, version 9.6.0 (www.rapidminer.com). We conclude the evidence of family history, smoking, alcohol consumption, male predominance, and head trauma are associated with cluster headaches. However, sex discrimination in familial cases needs to be revisited because of the female predominance reported by familial history and CH association studies.

Acute Omental Infarction Mimicking Acute Appendicitis.

Acute abdominal pain is a common cause of visits to the emergency department. Acute appendicitis remains the most common indication for abdominal surgical intervention in the pediatric age group. However, several conditions may present with a clinical picture similar to that of acute appendicitis. We report the case of a 7-year-old girl with a history of right lower quadrant abdominal pain of two days in duration. The pain was associated with vomiting and was exacerbated by movement. Abdominal examination revealed a localized tenderness in the right iliac fossa with guarding, giving the impression of acute appendicitis. After a thorough investigation, the patient was diagnosed as having acute omental infarction given the radiological findings seen in the computed tomography scan. The patient was successfully managed conservatively with analgesics and anti-inflammatory drugs. Physicians should keep a high index of suspicion for this condition when encountering a patient presenting with an acute right lower quadrant abdominal pain. Imaging modalities play a pivotal role in making the diagnosis.
