Mental disorders are one of the health disorders that contribute to high rates of disability and mortality worldwide. The current therapeutic modalities used to treat mental disorders are medical and psychological approaches, but it becomes problematic in some conditions, such as drug-resistant mental disorders. Radio Electric Asymmetric Conveyer (REAC) technology can be used as an alternative to overcome this problem. This technology uses radio waves which are guaranteed to be non-invasive and do not cause side effects. This technology enables neuromodulation effects by maximizing cell polarity and optimizing endogenous bioelectric activity. Of course, the REAC's mechanism as a neuromodulator and being a non-invasive technology is safe to use. It allows REAC to be used as an adjuvant therapy to reduce symptoms of several mental disorders such as depression, anxiety, bipolar disorder, phobias, and stress.

Background: The process of hepatic fibrosis is common to the various etiologies of chronic liver disease such as viral hepatitis B. Objective: To evaluate hepatic fibrosis by non-invasive markers such as Aspartate-to-Platelet Ratio Index (APRI), fibrosis-4 (FIB-4), fibrotest and fibroscan. Patients and Method: This was a descriptive study during a period of 32 months. Included in our study were the records of outpatients, chronic carriers of hepatitis B virus without viral co-infection C, D or HIV, followed in the Gastroenterology unit of the Campus Teaching Hospital of Lome-Togo. Results: We retained 222 patients. Among the patients, 148 patients (66.67%) were classified in Phase 3 (inactive carrying). Only 10 patients (4.50%) had a APRI score indicating a fibrosis stage ≥ F4 (presence of cirrhosis). A FIB-4 score indicating the presence of cirrhosis was found in 12 patients (5.40%). The most represented stage at fibrotest was the F0 stage (45.45%). Cirrhosis was noted in 6.06% of cases at fibroscan. Patients with APRI score ≤ 2 (96.23%) had a FIB-4 score ≤ 3.25, (p = 0.0088). Conclusion: The evaluation of hepatic fibrosis during chronic hepatopathies is essential for patients care because it influences therapeutic decisions.

Electrical Impedance Tomography (EIT) is known as non-invasive method to detect and classify the abnormal breast tissues. Reimaging conductivity distribution within an area of the subject reveal abnormal tissues inside that area. In this work, we have created a very low-cost system with a simple 16-electrode phantom for doing research purposes. The EIT data were measured and reconstructed with EIDORS software.

AbstractClinical oncologists need more reliable and non-invasive diagnostic and prognostic biomarkers to follow-up cancer patients. However, the existing biomarkers are often invasive and costly, emphasizing the need for the development of biomarkers to provide convenient and precise detection. Extracellular vesicles especially exosomes have recently been the focus of translational research to develop non-invasive and reliable biomarkers for several diseases such as cancers, suggesting as a valuable source of tumor markers. Exosomes are nano-sized extracellular vesicles secreted by various living cells that can be found in all body fluids including serum, urine, saliva, cerebrospinal fluid, and ascites. Different molecular and genetic contents of their origin such as nucleic acids, proteins, lipids, and glycans in a stable form make exosomes a promising approach for various cancers’ diagnoses, prediction, and follow-up in a minimally invasive manner. Since exosomes are used by cancer cells for intercellular communication, they play a critical role in the disease process, highlighting the importance of their use as clinically relevant biomarkers. However, regardless of the advantages that exosome-based diagnostics have, they suffer from problems regarding their isolation, detection, and characterization of their contents. This study reviews the history and biogenesis of exosomes and discusses non-coding RNAs (ncRNAs) and their potential as tumor markers in different types of cancer, with a focus on next generation sequencing (NGS) as a detection method. Moreover, the advantages and challenges associated with exosome-based diagnostics are also presented.

Background: Ophthalmia neonatorum (ON) is the most widespread eye infection occurring in the first 28 days of life. Although most of these cases are benign, some may progress to systemic complications or blindness if left untreated. Objectives: The current study was conducted with the aim of revealing the bacteriological causes of conjunctivitis in neonates and the antibiotic sensitivity pattern of these bacteria. Subjects and methods: The study included all neonates at the age of 1 to 28 days presenting at the neonatal nurseries with Neonatal Intensive Care Unit (NICU) and level II care beds in three hospitals; Authority of Al-Thawra General Hospital, Al-Kuwait University Hospital and Al-Sabeen Maternity and Child Hospital in Sana’a city, Yemen. A full history was taken from each nurse and mothers of the neonates included in the study in which the findings were recorded in a predesigned questionnaire including socio demographic, maternal clinical information and therapeutic interventions. To isolate the causative agent, the conjunctival swabs were inoculated on proper media and bacteria were identified by standard microbiological methods and antibiotic resistance was done for the isolates. Results: 203 swabs were collected from newborns with eye discharge over a nine-month period. Positive growth rate was 51.7%, males were more affected (57.1%), 80% of affected neonates had low birth weight, 71.4% of preterm infants were most affected (p <0.01).  There was a significant relationship between invasive and non-invasive mechanical ventilation with neonatal conjunctivitis (p<0.05). Gentamicin showed good in vitro sensitivity to all bacteria isolated, Staphylococcus aureus (83%), Escherichia coli 84.6%, with P. aeruginosa it was 60%. Conclusion: The vast majority of cases of neonatal conjunctivitis were mild with a high level of occurrence, Staphylococcus aureus and Klebsiella pneumoniae were the major bacterial agents, neonatal conjunctivitis most likely to be a hospital-acquired infection. There was a significant association between phototherapy, non-invasive ventilation and incidence of neonatal conjunctivitis . Gentamicin had high activity against the bacteria isolated in this study.                   Peer Review History: Received: 9 November 2021; Revised: 11 December; Accepted: 27 December, Available online: 15 January 2022 Academic Editor: Dr. Sally A.

Abstract We describe the first application of the Near-infrared spectroscopy (NIRS) technique to detect Plasmodium falciparum and P. vivax malaria parasites through the skin of malaria positive and negative human subjects. NIRS is a rapid, non-invasive and reagent free technique which involves rapid interaction of a beam of light with a biological sample to produce diagnostic signatures in seconds. We used a handheld, miniaturized spectrometer to shine NIRS light on the ear, arm and finger of P. falciparum (n=7) and P. vivax (n=20) positive people and malaria negative individuals (n=33) in a malaria endemic setting in Brazil. Supervised machine learning algorithms for predicting the presence of malaria were applied to predict malaria infection status in independent individuals (n=12). Separate machine learning algorithms for differentiating P. falciparum from P. vivax infected subjects were developed using spectra from the arm and ear of P. falciparum and P. vivax (n=108) and the resultant model predicted infection in spectra of their fingers (n=54).NIRS non-invasively detected malaria positive and negative individuals that were excluded from the model with 100% sensitivity, 83% specificity and 92% accuracy (n=12) with spectra collected from the arm. Moreover, NIRS also correctly differentiated P. vivax from P. falciparum positive individuals with a predictive accuracy of 93% (n=54). These findings are promising but further work on a larger scale is needed to address several gaps in knowledge and establish the full capacity of NIRS as a non-invasive diagnostic tool for malaria. It is recommended that the tool is further evaluated in multiple epidemiological and demographic settings where other factors such as age, mixed infection and skin colour can be incorporated into predictive algorithms to produce more robust models for universal diagnosis of malaria.
