Methods and systems for identifying and/or treating urinary disorders are provided. The methods and systems generally operate by obtaining a urine sample from a subject, identifying (such as by using nucleic acid sequencing) an abundance of a first set of one or more microbes (such as one or more bacteria or viruses) in the urine sample, and determining whether the subject suffers from a urinary disorder based on the abundance of the first set of one or more microbes. In some cases, the methods and systems further operate by identifying a second set of microbes to supplement a microbiome in the urinary tract of the subject. In some instances, the methods and systems further operate by treating the urinary disorder using the second set of microbes. In some instances a preservation solution is utilized.

Methods and devices for diagnosing, monitoring, or determining diabetic nephropathy or an associated disorder in a mammal are described. In particular, methods and devices for diagnosing, monitoring, or determining diabetic nephropathy or an associated disorder using measured concentrations of a combination of three or more analytes in a test sample taken from the mammal are described.

A method for diagnosing interstitial cystitis includes measuring at least any one kind of lysophosphatidylcholine. A system and program for diagnosing a possibility of interstitial cystitis or bladder pain syndrome is also provided.

Provided herein are compositions, systems, and methods for treating a disease, such as kidney and/or cardiovascular disease, with an agent that reduces the production of trimethylamine (TMA) or trimethylamine-n-oxide (TMAO) in a subject. In certain embodiments, the agent is: i) 3,3-dimethyl-1-butanol (DMB) or a DMB derivative or related compound, ii) acetylsalicylic acid or derivative thereof (e.g., with an enteric coating for delivery to the colon and/or cecum); iii) a flavin monooxygenase 3 (FMO3) inhibitor; iv) a gut TMA lyase inhibitor; v) an antibiotic or antimicrobial; vi) a probiotic or prebiotic; vii) an antiplatelet agent; or viii) a TMA and/or TMAO sequestering agent.

The present invention relates in general to the field of muscle disease. In particular, the invention relates to a method for determining if a subject has sarcopenia or has an increased risk of developing sarcopenia. A method of predicting the responsiveness of said subject to nutritional intervention is also provided.

The present invention relates to systems, kits, and methods for identifying subjects with increased levels of N6-trimethyl-lysine (TML) or the combination of TML and trimethylamine-n-oxide (TMAO), as well as methods of determining risk of disease (e.g., kidney disease or heart failure) based on such levels. In certain embodiments, subjects with elevated TML, or TML and TMAO are treated with a therapeutic (e.g., one that inhibits the TMA/FMO3/TMAO pathway).

The present invention relates to methods for detecting, diagnosing and/or treating ulcerative interstitial cystitis (UIC) by detecting in a urine sample from a patient the levels of each of the proteins IL-6, IL-8 and GRO [also known as CXCL 1 (chemokine C-X-C motif ligand 1]. In some embodiments, the method also includes diagnosing the patient with UIC when each of the proteins IL-6, IL-8 and GRO in the urine sample is at a different level than a statistically validated threshold for the respective proteins. In some embodiments a companion diagnostic, e.g., a cystoscopy, is used in conjunction with the protein biomarker diagnostic. In some embodiments, once UIC is diagnosed, the patient is treated for the UIC.

The current disclosure provides methods for detecting and analyzing K17 expression in a bladder sample obtained from a subject. The current disclosure also pertains to methods and kits for identifying a mammalian subject with bladder cancer by detecting the expression of K17 in a sample. The present methods include both cell-based and cell-free methods for determining the level of keratin 17 in a sample obtained from the bladder of a subject.

Provided herein are compositions, systems, and methods for treating a disease, such as kidney and/or cardiovascular disease, with an agent that reduces the production of trimethylamine (TMA) or trimethylamine-n-oxide (TMAO) in a subject. In certain embodiments, the agent is: i) 3,3-dimethyl-1-butanol (DMB) or a DMB derivative or related compound, ii) acetylsalicylic acid or derivative thereof (e.g., with an enteric coating for delivery to the colon and/or cecum); iii) a flavin monooxygenase 3 (FMO3) inhibitor; iv) a gut TMA lyase inhibitor; v) an antibiotic or antimicrobial; vi) a probiotic or prebiotic; vii) an antiplatelet agent; or viii) a TMA and/or TMAO sequestering agent.

The technology described herein is directed to the diagnosis and treatment of androgen disorders and/or deficiencies, e.g. low testosterone.
