We genetically characterized seven nearly complete genomes in the protoparvovirus genus from the feces of children with diarrhea. The viruses, provisionally named cutaviruses (CutaV), varied by 1-6% nucleotides and shared ~76% and ~82% amino acid identity with the NS1 and VP1 of human bufaviruses, their closest relatives. Using PCR, cutavirus DNA was found in 1.6% (4/245) and 1% (1/100) of diarrhea samples from Brazil and Botswana respectively. In silico analysis of pre-existing metagenomics datasets then revealed closely related parvovirus genomes in skin biopsies from patients with epidermotropic cutaneous T-cell lymphoma (CTCL or mycosis fungoides). PCR of skin biopsies yielded cutavirus DNA in 4/17 CTCL, 0/10 skin carcinoma, and 0/21 normal or noncancerous skin biopsies. In situ hybridization of CTCL skin biopsies detected viral genome within rare individual cells in regions of neoplastic infiltrations. The influence of cutavirus infection on human enteric functions and possible oncolytic role in CTCL progression remain to be determined.

Annually, thousands of individuals suffer from skin injuries resulting from trauma, surgeries, or diabetes. Inadequate wound treatment can delay healing and increase the risk of severe infections. In this context, a promising synthetic polymer with potent antimicrobial properties, Poly{2-[(methacryloyloxy)ethyl]trimethylammonium chloride} (PMETAC), is synthesized and crosslinked with N,N'-Methylenebis(acrylamide) (BIS) in the presence of Chitosan (CH), a natural, biocompatible polysaccharide that promotes cell regeneration and provides additional beneficial properties.

Phyllodes tumor is a type of fibroepithelial neoplasm involving the breast. This tumor is rarely reported in adolescents and the elderly and has a peak incidence in middle-aged women. Histologically, phyllodes tumors are classified as benign, borderline, or malignant.

We present a 22-year-old man with a well-established medical history who had been complaining of 4 days of frothy dark urine, bilateral lower limb swelling, and puffiness on his face. For a month before his presentation, he had many bilateral skin lesions on his lower limbs that were leaking pus.

Detection of biomarkers associated with physiological conditions provides critical insights into healthcare and disease management. However, challenges in sampling and analysis complicate the detection and quantification of protein biomarkers within the epidermal layer of the skin and in viscous liquid biopsy samples. Here, we present the "Lab-on-the-Needles" concept, utilizing a microneedle patch-based sensing box (MNP-based SenBox) for mobile healthcare applications.
