Predictors of patient satisfaction with Mohs micrographic surgery at time of surgery and 3 months postsurgery: A prospective cohort study.

BACKGROUND: Despite the importance of patient satisfaction in ensuring high-quality care, studies investigating patient satisfaction in Mohs micrographic surgery (MMS) are limited. OBJECTIVE: We investigated the factors associated with patient satisfaction in MMS for nonmelanoma skin cancer and how patient satisfaction changes in the postoperative period. METHODS: In this prospective cohort study including 100 patients, patient satisfaction surveys were administered at the time of surgery and at 3 months postsurgery. Sociodemographic characteristics, medical history, and surgical parameters were collected by chart review. Univariate linear and logistic regression models were created to examine these relationships. RESULTS: Decreased satisfaction was observed in patients requiring 3 or more MMS stages both at the time of surgery (P = .047) and at 3 months post-surgery (P = .0244). Patients with morning procedures ending after 1:00 pm had decreased satisfaction at the time of surgery (P = .019). A decrease in patient satisfaction between the time of surgery and 3 months postsurgery was observed in patients with surgical sites on the extremities (P = .036), larger preoperative lesion sizes (P = .012), and larger defect sizes (P = .033). LIMITATIONS: Single-institution data, self-selection bias, and recall bias. CONCLUSION: Patient satisfaction with MMS is impacted by numerous factors and remains dynamic over time.

A Novel Imidazole Bound Schiff Base as Highly Selective "Turn-on" Fluorescence Sensor for Zn2+ and Colorimetric Kit for Co2.

An imidazole based Schiff base (2-[(1H-imidazole-2-ylmethylene)-amino]-4-methyl-phenol) (IMP), with an imine unit, has been designed and characterized by various standard methods. The evaluation of the probe as a fluorogenic sensor for Zn2+ and a chromogenic sensor for Co2+ has been rationalized in terms of the PET mechanism. In the presence of Zn2+, a light yellow colored solution of IMP with maximum absorption of 364 nm becomes bright yellow with maximum absorption of 410 nm and a measurable fluorescent signal at 612 nm with bathochromic enhancement. The sensitivity of the fluorescent based assay (6.78 × 10-9 M) for Zn2+ is far below the limit in the World Health Organization (WHO) guidelines for drinking water (7.6 × 10-5 M) and therefore it is capable of being a practical system for the monitoring of Zn2+ concentrations in aqueous samples. Moreover, IMP showed a highly selective colorimetric response to Co2+ by displayed an obvious pink color upon addition of metal solution immediately without any interference from other ions. These results provide a new approach for selectively recognizing the two most important trace elements in the human body simultaneously, for Zn2+ by emission spectra and Co2+ by the naked eye.

Synthesis and Characterization of a Novel Heterocyclic Schiff Base and Development of a Fluorescent Sensor for Vitamin B12.

A heterocyclic Schiff base (MPDPI)was synthesized by the condensation reaction of 1-phenylisatin with 4,5-dimethylphenylene diamine. It was characterized by using spectroscopic methods including UV visible, Infrared, 1H-NMR, 13C-NMR and mass spectrometry. It acts as the fluorescent probe for the detection of Vitamin B12 (Vit.B12) which shows high selectivity over other species via dynamic quenching mechanism. It is also highly sensitive towards Vit.B12 with a detection limit of [Formula: see text]M and showed a linear concentration ranging from [Formula: see text] to [Formula: see text]. Effect of other coexisting species was also studied. The satisfactory results were also obtained in real samples.Since, there are only few reports on Vit.B12, development of selective fluorescent probes for Vit.B12 would be worthwhile.

Racial, ethnic, and biologic sex disparities in outpatient laboratory monitoring of isotretinoin use: a cross-sectional study.

BACKGROUND: Isotretinoin is commonly used for the treatment of acne. Despite high efficacy, isotretinoin has a side effect profile that prompts regular outpatient laboratory monitoring. Emerging evidence suggests clinically significant lab abnormalities are rare. Racial, ethnic, and biologic sex disparities in laboratory monitoring of isotretinoin have yet to be characterized. METHODS: This study explores disparities in laboratory monitoring of patients prescribed isotretinoin, factoring in the COVID-19 pandemic given its impacts on laboratory monitoring. Two populations were evaluated: all patients taking isotretinoin, and patients taking isotretinoin with no metabolic, cardiovascular, hematologic, hepatic, or renal comorbidities. The latter population was included to screen out patients who might receive increased laboratory testing for conditions besides isotretinoin use. RESULTS: Our data reveal that African-American, Asian, and Hispanic patients prescribed isotretinoin were more likely than Caucasian patients to receive orders for outpatient laboratory monitoring. These disparities persisted independent of comorbidities that may prompt additional testing, suggesting that non-Caucasian patients bear an additional testing burden even when their comorbidities were matched to their peers. Disparities persisted in the setting of reduced laboratory monitoring due to the COVID-19 pandemic. CONCLUSIONS: These data reveal that patients of color are more likely to receive outpatient laboratory monitoring for isotretinoin prescriptions. There is an opportunity for testing standardization to improve medication access, decrease burden and costs for patients and the healthcare system, and decrease racial disparities in prescribing and monitoring of isotretinoin. Dermatology clinics may benefit from standard operating procedures outlining for whom regular monitoring is needed.

An organizational framework for patient-reported outcome instruments in dermatologic surgery: a systematic review and qualitative analysis.

Patient-reported outcomes (PROs) describe measures of a patient's experience throughout medical care as reported by the patient (Mercieca-Bebber et al. in Patient Relat Outcome Meas, 2018). Various PRO instruments exist. It is challenging to select appropriate instruments given the absence of an organizational framework which describes all measurable PROs in dermatologic surgery and represents which instruments measure which outcomes. Our objective was to systematically review all validated PRO instruments in dermatologic surgery and use qualitative analysis to develop an organizational framework representing PRO measures and instruments. PubMed/MEDLINE, Embase, CINAHL, PsycINFO, and Cochrane databases were searched to retrieve validated PRO instruments in the dermatologic surgery population. The constant comparative method of qualitative analysis was used to develop an organizational framework representing all PROs in dermatologic surgery. All instruments were sorted into this framework. The search identified 3195 articles; 35 validated instruments were extracted and qualitatively analyzed. The organizational framework sorted all instruments into 36 PRO measures aligned with the National Institutes of Health Patient-Reported Outcomes Measurement Information System (Gershon RC, Rothrock N, Hanrahan R, et al (2010) The use of PROMIS and assessment center to deliver patient-reported outcome measures in clinical research). Measures were grouped into four categories (expectations, satisfaction, quality of life, needs) describing how patients experience these outcomes and lenses through which researchers can evaluate them. In conclusion, we have proposed an organizational framework for use in choosing validated instruments to develop and answer PRO research questions.

A multidisciplinary transitional pain service to improve pain outcomes following trauma surgery: a preliminary report.

OBJECTIVES: Trauma (i.e., musculoskeletal injury from a blunt or penetrating force) can change the trajectory of a person's life. Patients often experience chronic pain, reduced quality of life, long-term opioid therapy, and psychiatric comorbidities after trauma surgery. This case report presents clinical outcomes of four patients who received postsurgical pain care in a transitional pain service (TPS) that provides long-term coordinated multimodal pain care, opioid tapering plans, and psychiatric care. METHODS: The Personalized Pain Program (PPP) measures prescription opioid use and patient-reported outcomes: pain severity and pain interference (Brief Pain Inventory), pain catastrophizing (Pain Catastrophizing Scale), insomnia severity (Insomnia Severity Index), physical and mental health functioning (SF-12 pre-COVID-19; SF-36 during COVID-19 pandemic) at initial and subsequent clinic visits. RESULTS: All four patients reduced their postsurgical opioid use with concurrent reductions in pain and improved functioning while receiving postoperative care in the PPP (average length of treatment: 2.8 years). Psychiatric co-treatment addressed the onset or exacerbation of mental health comorbidities following trauma. CONCLUSIONS: Long-term multidisciplinary pain care may improve post-trauma recovery and reduce risks of long-term opioid therapy and disability. Prospective studies are needed to evaluate the effectiveness of TPSs for patients undergoing trauma surgery.

Patient Experiences and Clinical Outcomes in a Multidisciplinary Perioperative Transitional Pain Service.

Siloed pain management across the perioperative period increases the risk of chronic opioid use and impedes postoperative recovery. Transitional perioperative pain services (TPSs) are innovative care models that coordinate multidisciplinary perioperative pain management to mitigate risks of chronic postoperative pain and opioid use. The objective of this study was to examine patients' experiences with and quality of recovery after participation in a TPS. Qualitative interviews were conducted with 26 patients from The Johns Hopkins Personalized Pain Program (PPP) an average of 33 months after their first PPP visit. A qualitative content analysis of the interview data showed that participants (1) valued pain expectation setting, individualized care, a trusting patient-physician relationship, and shared decision-making; (2) perceived psychiatric treatment of co-occurring depression, anxiety, and maladaptive behaviors as critical to recovery; and (3) successfully sustained opioid tapers and experienced improved functioning after PPP discharge. Areas for improved patient-centered care included increased patient education, specifically about the program, continuity of care with pain specialists while tapering opioids, and addressing the health determinants that impede access to pain care. The positive patient experiences and sustained clinical benefits for high-risk complex surgical patient support further efforts to implement and adapt similar models of perioperative pain care.

Measuring urinary tubular biomarkers in type 2 diabetes does not add prognostic value beyond established risk factors.

Tubulointerstitial disease plays an important role in the pathophysiology of diabetic kidney disease. To determine whether biomarkers of tubular injury could predict renal outcome and mortality in patients with type 2 diabetes, we measured urinary levels of kidney injury molecule-1 (KIM-1) and glycoprotein non-metastatic melanoma B (Gpnmb), both normalized to the urinary creatinine, in 978 individuals from the Edinburgh Type 2 Diabetes Study. At baseline, 238 patients had an estimated glomerular filtration rate (eGFR) below 60 ml/min/1.73 m2 while 147 and 15 patients had microalbuminuria or overt proteinuria, respectively. Both the urine KIM-1 and Gpnmb to creatinine ratios correlated with the urinary albumin to creatinine ratio, the duration of diabetes, and the stringency of glycemic control but not with blood pressure or baseline eGFR. Higher ratios of each marker were associated with a faster decline in kidney function during 4 years of follow-up; however, this was not independent of the urinary albumin to creatinine ratio. Higher KIM-1, but not Gpnmb ratios were associated with an increased risk of mortality, but this association was no longer significant after adjustment for other risk factors, in particular albuminuria. Thus, tubular injury in persons with type 2 diabetes may contribute to the decline in kidney function; however, measuring the urinary concentration of these two tubular biomarkers does not confer additional prognostic information beyond established risk factors.

Role of coronary angiogram before transcatheter aortic valve implantation.

BACKGROUND: Coexistent coronary artery disease is commonly seen in patients undergoing transcatheter aortic valve implantation (TAVI). Previous studies showed that pre-TAVI coronary revascularisation was not associated with improved outcomes, challenging the clinical value of routine coronary angiogram (CA). AIM: To assess whether a selective approach to perform pre-TAVI CA is safe and feasible. METHODS: This was a retrospective non-randomised single-centre analysis of consecutive patients undergoing TAVI. A selective approach for performing CA tailored to patient clinical need was developed. Clinical outcomes were compared based on whether patients underwent CA. The primary endpoint was a composite of all-cause mortality, myocardial infraction, repeat CA, and re-admission with heart failure. RESULTS: Of 348 patients (average age 81 ± 7 and 57% male) were included with a median follow up of 19 (9-31) mo. One hundred and fifty-four (44%) patients, underwent CA before TAVI procedure. Patients who underwent CA were more likely to have previous myocardial infarction (MI) and previous percutaneous revascularisation. The primary endpoint was comparable between the two group (22.6% vs 22.2%; hazard ratio 1.05, 95%CI: 0.67-1.64, P = 0.82). Patients who had CA were less likely to be readmitted with heart failure (P = 0.022), but more likely to have repeat CA (P = 0.002) and MI (P = 0.007). In those who underwent CA, the presence of flow limiting lesions did not affect the incidence of primary endpoint, or its components, except for increased rate of repeat CA. CONCLUSION: Selective CA is a feasible and safe approach. The clinical value of routine CA should be challenged in future randomised trials.

Small-molecule AgrA inhibitors F12 and F19 act as antivirulence agents against Gram-positive pathogens.

Small-molecule antivirulence agents represent a promising alternative or adjuvant to antibiotics. These compounds disarm pathogens of disease-causing toxins without killing them, thereby diminishing survival pressure to develop resistance. Here we show that the small-molecule antivirulence agents F12 and F19 block staphylococcal transcription factor AgrA from binding to its promoter. Consequently, toxin expression is inhibited, thus preventing host cell damage by Gram-positive pathogens. Broad spectrum efficacy against Gram-positive pathogens is due to the existence of AgrA homologs in many Gram-positive bacteria. F12 is more efficacious in vitro and F19 works better in vivo. In a murine MRSA bacteremia/sepsis model, F19 treatment alone resulted in 100% survival while untreated animals had 70% mortality. Furthermore, F19 enhances antibiotic efficacy in vivo. Notably, in a murine MRSA wound infection model, combination of F19 with antibiotics resulted in bacterial load reduction. Thus, F19 could be used alone or in combination with antibiotics to prevent and treat infections of Gram-positive pathogens.

Myocardial inflammation, injury and infarction during on-pump coronary artery bypass graft surgery.

BACKGROUND: Myocardial inflammation and injury occur during coronary artery bypass graft (CABG) surgery. We aimed to characterise these processes during routine CABG surgery to inform the diagnosis of type 5 myocardial infarction. METHODS: We assessed 87 patients with stable coronary artery disease who underwent elective CABG surgery. Myocardial inflammation, injury and infarction were assessed using plasma inflammatory biomarkers, high-sensitivity cardiac troponin I (hs-cTnI) and cardiac magnetic resonance imaging (CMR) using both late gadolinium enhancement (LGE) and ultrasmall superparamagnetic particles of iron oxide (USPIO). RESULTS: Systemic humoral inflammatory biomarkers (myeloperoxidase, interleukin-6, interleukin-8 and c-reactive protein) increased in the post-operative period with C-reactive protein concentrations plateauing by 48 h (median area under the curve (AUC) 7530 [interquartile range (IQR) 6088 to 9027] mg/L/48 h). USPIO-defined cellular myocardial inflammation ranged from normal to those associated with type 1 myocardial infarction (median 80.2 [IQR 67.4 to 104.8] /s). Plasma hs-cTnI concentrations rose by ≥50-fold from baseline and exceeded 10-fold the upper limit of normal in all patients. Two distinct patterns of peak cTnI release were observed at 6 and 24 h. After CABG surgery, new LGE was seen in 20% (n = 18) of patients although clinical peri-operative type 5 myocardial infarction was diagnosed in only 9% (n = 8). LGE was associated with the delayed 24-h peak in hs-cTnI and its magnitude correlated with AUC plasma hs-cTnI concentrations (r = 0.33, p < 0.01) but not systemic inflammation, myocardial inflammation or bypass time. CONCLUSION: Patients undergoing CABG surgery invariably have plasma hs-cTnI concentrations >10-fold the 99th centile upper limit of normal that is not attributable to inflammatory or ischemic injury alone. Peri-operative type 5 myocardial infarction is often unrecognised and is associated with a delayed 24-h peak in plasma hs-cTnI concentrations.

Immunogenicity of a three dose and five dose oral human rotavirus vaccine (RIX4414) schedule in south Indian infants.

AIM: This study was undertaken to compare the immunogenicity of a three dose and five dose schedule of an oral live-attenuated human rotavirus vaccine, Rotarix in south Indian infants. METHOD: Healthy infants (N=90), six to seven weeks of age were enrolled to receive three doses (n=45) or five doses of Rotarix vaccine (n=45) along with other scheduled vaccines, each dose separated by a four week interval. Blood samples were taken before vaccination and one month post-dose three in the Rotarix three dose group and one month post-dose five in the Rotarix five dose group; all were tested for anti-rotavirus IgA by an antibody sandwich enzyme immunoassay. RESULTS: At baseline, >50% of infants had >20 units of anti-rotavirus IgA. The seroconversion rates after three and five doses were low and not significantly different in the two groups. However, among vaccine responders, children seropositive at baseline showed a much greater absolute increase in IgA antibody levels than children seronegative at baseline. CONCLUSIONS: Rotarix vaccine showed low immunogenicity in south Indian children and increasing the number of doses did not increase the proportion of infants seroconverting after vaccination.
