The Promise of Cilnidipine in Hypertension with Comorbidities: National Consensus Statement: National Consensus Group Comprises Cardiologists, Nephrologists, and Diabetologists from India in a National Meet at New Delhi held on 22nd May 2022.

The rapidly increasing burden of hypertension is responsible for premature deaths from cardiovascular disease (CVD), renal disease, and stroke, with a tremendous public health and financial burden. Hypertension detection, treatment, and control vary worldwide; it is still low, particularly in low- and middle-income countries (LMICs). High blood pressure (BP) and CVD risk have a strong, linear, and independent association. They contribute to alarming numbers of all-cause and CVD deaths. A major culprit for increased hypertension is sympathetic activity, and further complications of hypertension are heart failure, ischemic heart disease (IHD), stroke, and renal failure. Now, antihypertensive interventions have emerged as a global public health priority to reduce BP-related morbidity and mortality. Calcium channel blockers (CCB) are highly effective vasodilators. and the most common drugs used for managing hypertension and CVD. Cilnidipine, with both L- and N-type calcium channel blocking activity, is a promising 4th generation CCB. It causes vasodilation via L-type calcium channel blockade and inhibits the sympathetic nervous system (SNS) via N-type calcium channel blockade. Cilnidipine, which acts as a dual L/N-type CCB, is linked to a reduced occurrence of pedal edema compared to amlodipine, which solely blocks L-type calcium channels. The antihypertensive properties of cilnidipine are very substantial, with low BP variability and long-acting properties. It is beneficial for hypertensive patients to deal with morning hypertension and for patients with abnormal nocturnal BP due to exaggerated sympathetic nerve activation. Besides its BP-lowering effect, it also exhibits organ protection via sympathetic nerve inhibition and renin-angiotensin-aldosterone system inhibition; it controls heart rate and proteinuria. Reno-protective, neuroprotective, and cardioprotective effects of cilnidipine have been well-documented and demonstrated.

Topical Diclofenac for Prevention of Capecitabine-Associated Hand-Foot Syndrome: A Double-Blind Randomized Controlled Trial.

PURPOSE: Hand-foot syndrome (HFS) is a dose-limiting side effect of capecitabine. Celecoxib prevents HFS by inhibiting cyclooxygenase-2 (COX-2) that is upregulated because of the underlying associated inflammation. However, systemic side effects of celecoxib have limited routine prescription. Topical diclofenac inhibits COX-2 locally with minimal risk of systemic adverse events. Therefore, we conducted this study to assess the efficacy of topical diclofenac in the prevention of capecitabine-induced HFS. METHODS: In this single-site phase III randomized double-blind trial, we enrolled patients with breast or GI cancer who were planned to receive capecitabine-based treatment. Participants were randomly assigned in a 1:1 ratio to receive topical diclofenac or placebo gel for 12 weeks or until the development of HFS, whichever occurred earlier. The primary end point was the incidence of grade 2 or 3 HFS (Common Terminology Criteria for Adverse Events version 5), which was compared between the two groups using simple logistic regression. RESULTS: In total, 264 patients were randomly assigned to receive topical diclofenac gel (n = 131) or placebo (n = 133). Grade 2 or 3 HFS was observed in 3.8% of participants in the diclofenac group compared with 15.0% in the placebo group (absolute difference, 11.2%; 95% CI, 4.3 to 18.1; P = .003). Grade 1-3 HFS was lower in the diclofenac group than in the placebo group (6.1% v 18.1%; absolute risk difference, 11.9%; 95% CI, 4.1 to 19.6). Capecitabine dose reductions because of HFS were less frequent in the diclofenac group (3.8%) than in the placebo group (13.5%; absolute risk difference, 9.7%; 95% CI, 3.0 to 16.4). CONCLUSION: Topical diclofenac prevented HFS in patients receiving capecitabine. This trial supports the use of topical diclofenac to prevent capecitabine-associated HFS.

Dexamethasone-free antiemetic strategy for highly emetogenic chemotherapy: safety and efficacy-pilot study.

OBJECTIVES: Dexamethasone sparing strategies have shown success. The feasibility of a dexamethasone-free antiemetic strategy remains undetermined. A prospective, single-arm, pilot study was planned to determine the efficacy of an olanzapine-based, dexamethasone-free, three-drug antiemetic regimen. METHODS: Chemotherapy naïve, adult patients (≥18 years) who received ondansetron, aprepitant and olanzapine during the first cycle of highly emetogenic chemotherapy were enrolled. The primary endpoint was the rate of complete response (CR: no vomiting and no use of rescue medications) during the overall period (0-120 hours). RESULTS: Out of the total of 101 patients enrolled, most were women (82%) and received anthracycline cyclophosphamide (73%) combination therapy. The rate of CR for the overall period was 65% (95% CI 55.2% to 74.5%). The rate of CR for the acute and delayed period was 79% (95% CI 70% to 86.7%) and 76% (95% CI 66.7% to 84.1%). The rate of nausea control rates for the acute, delayed and overall periods were 34%, 29% and 24%, respectively. The grade I, II and III sedation rates over the 5 days were 8%, 5% and 1%, respectively. CONCLUSIONS: The dexamethasone-free antiemetic strategy showed modest efficacy with low incidence of clinically significant somnolence. There is a need to prospectively investigate the role of dexamethasone in the era of newer potent antiemetics in a randomised fashion. TRIAL REGISTRATION NUMBER: CTRI/2021/07/034813.

Update on the systemic management of noninfectious uveitis in children and adolescents.

Noninfectious uveitis (NIU) in children and adolescents is a rare but treatable cause of visual impairment in children. Treatments for pediatric NIU and their side effects, along with the risks of vision loss and the need for long-term disease monitoring, pose significant challenges for young patients and their families. Treatment includes local and systemic approaches and this review will focus on systemic therapies that encompass corticosteroids, conventional synthetic disease-modifying antirheumatic drugs (csDMARD), and biological disease-modifying antirheumatic drugs (bDMARD). Treatment is generally planned in a stepwise approach. Methotrexate is well-established as the preferential csDMARD in pediatric NIU. Adalimumab, an antitumor necrosis factor (TNF) agent, is the only bDMARD formally approved for pediatric NIU and has a good safety and efficacy profile. Biosimilars are gaining increasing visibility in the treatment of pediatric NIU. Other bDMARD with some evidence in literature for the treatment of pediatric NIU include infliximab, tocilizumab, abatacept, rituximab and, more recently, Janus kinase inhibitors. Important aspects of managing children on these systemic therapies include vaccination issues, risk of infection, and psychological distress. Also, strategies need to address regarding primary nonresponse/secondary loss of response to anti-TNF treatment, biological switching, and monitoring regimens for these drugs. Optimal management of pediatric uveitis involves a multidisciplinary team, including specialist pediatric uveitis and rheumatology nurses, pediatric rheumatologists, psychological support, orthoptic and optometry support, and play specialists.

The Gut-Brain Connection: A Case Report on Depression in Ulcerative Colitis and Novel Treatment Approach.

Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by mucosal inflammation in the colon, leading to a range of gastrointestinal symptoms. Emerging research has shown significant comorbidity between UC and depression, with a bidirectional relationship that further complicates disease management and patient well-being. Depression is more prevalent among individuals with UC, affecting 27% of them, compared to the general population's 12%. Factors contributing to depression in UC patients include the chronic nature of the disease, frequent hospitalizations, unpredictable flares, and associated physical symptoms such as pain, fatigue, and altered body image. Depression, in turn, can exacerbate UC symptoms, leading to a vicious cycle of disease progression and emotional distress. A new treatment approach has surfaced as a solution to the challenge of providing effective care to patients with UC who also suffer from depression. This approach involves a collaborative effort by a multidisciplinary team consisting of gastroenterologists, psychiatrists, psychologists, and dietitians, who work together to provide comprehensive care to UC patients with depression. This case report discussed the psychiatric presentation and management of a 75-year-old male who developed severe depression following his diagnosis of UC. This patient demonstrated significant improvement in depressive symptoms with the integrated care approach. This case highlights the importance of recognizing and addressing the psychological impact of chronic inflammatory conditions such as UC and the potential benefits of integrating psychopharmacological interventions into the treatment plan. Further research is essential to establish the effectiveness of this approach and refine its implementation in clinical practice.

Preoperative Diffusion Tensor Imaging in Supratentorial Intra-Axial Brain Tumors: Its Role in Predicting Tumor Histology and Prognosis as well in Surgical Planning and Resection.

Objective There are a large number of prospective studies that use diffusion tensor imaging (DTI) to show the relationship between intracranial tumors and white matter (WM) fibers. We studied the role of DTI in supratentorial intra-axial (ST-IA) tumors of the brain in deciding the surgical approach with maximal resection and minimal or no deficit and in predicting the histological characterization of the tumor and the neurological outcome. Methods A total of 91 cases of ST-IA tumors were included in our study. The neurological status of the patients was assessed preoperatively, and the tumor volume and DTI pattern were noted radiologically. Surgical plan was decided by the senior consultants of the neurosurgery department taking into consideration the findings of tractography and magnetic resonance imaging. The neurological status and the extent of resection were evaluated postoperatively, and the correlation between histopathology with DTI was studied. Results Of the 91 patients, 25 had high-grade glioma (HGG), 60 had low-grade glioma (LGG), and 6 were metastatic lesions. Gross total excisions were done mostly in patients with DTI showing displaced fibers and subtotal/partial resections were done mostly in disrupted/infiltrated tracts, which was statistically significant. The correlation between histopathology and tractography revealed that intact/displaced tracts were seen mostly in LGG (79%), whereas 86% of HGG showed disrupted/infiltrated fibers; both were statistically significant. Conclusion Preoperative DTI in ST-IA brain tumors is an important tool for deciding the appropriate surgical approach for maximal safe resection, thus improving the post-op neurological outcome in patients. It also helps in predicting the tumor histology while also serving as an important prognostication indicator.

Efficacy of different respiratory supports to prevent hypoxia during flexible bronchoscopy in patients of COPD: a triple-arm, randomised controlled trial.

BACKGROUND: Patients with chronic-obstructive-pulmonary-disease (COPD) undergo bronchoscopy for various reasons, and are at relatively higher risk of complications. This study evaluated the efficacy of non-invasive ventilation (NIV) and high-flow-oxygen-therapy (HFOT) compared with conventional-oxygen-therapy (COT) in patients with COPD undergoing bronchoscopy, to prevent hypoxia. METHODS: It was a triple-arm, open-label, randomised controlled trial. Ninety patients with COPD were randomly assigned into three intervention arms in 1:1:1 ratio. The incidence of hypoxia, lowest recorded oxygen saturation measured by plethysmography (SpO2), ECG, patient vitals and comfort levels were assessed. RESULTS: Mean age of the study population was 61.71±7.5 years. Out of 90 cases enrolled, 51, 34 and 5 were moderate, severe and very-severe COPD, respectively, as per GOLD (Global Initiative for Chronic Obstructive Lung Disease) classification. Rest of the baseline characteristics were similar. SpO2 during flexible bronchoscopy (FB) was lowest in COT group (COT: 87.03±5.7% vs HFOT: 95.57±5.0% vs NIV: 97.40±1.6%, p<0.001). Secondary objectives were similar except respiratory-rate (breaths-per-minute) which was highest in COT group (COT: 20.23±3.1 vs HFOT: 18.57±4.1 vs NIV: 16.80±1.9, p<0.001). Whereas post FB partial of oxygen in arterial blood was highest in NIV group (NIV: 84.27±21.6 mm Hg vs HFOT: 69.03±13.6 mm Hg vs COT: 69.30±11.9 mm Hg, p<0.001). Post FB partial pressure of carbon dioxide in arterial blood was similar in the three arms. Operator's ease-of-performing-procedure was least in the NIV group as assessed with Visual Analogue Scale (p<0.01). A higher number of NIV group participants reported nasal pain as compared with the other two arms (p<0.01). CONCLUSION: NIV and HFOT are superior to COT in preventing hypoxia during bronchoscopy, but NIV is associated with poor patient-tolerance and inferior operator's ease of doing procedure.

A Case of Cannabis-Induced Catatonia and Management With Electroconvulsive Therapy.

This is a case of cannabis-induced catatonia in an 18-year-old Hispanic male with no prior psychiatric history. Shortly after consuming marijuana, the patient experienced catatonic symptoms and demonstrated resistance to several medicinal therapies. Electroconvulsive therapy (ECT) proved to be a useful treatment choice, resulting in significant improvement in symptoms. This example emphasizes the potential dangers of cannabis usage, particularly in susceptible individuals, and underscores the importance of recognizing and treating catatonia as a possible side effect of cannabis use.

Role of Janus Kinase inhibitors in the management of pulmonary involvement due to Long COVID-19 disease: A case control study.

OBJECTIVES: Ongoing symptomatic coronavirus disease 2019 (OSC) is defined as persistent symptoms beyond 4 weeks of acute illness. OSC leads to prolonged hospitalization and oxygen dependence. We aimed to find the outcome of Janus kinase inhibitors (JAKi) as a steroid-sparing agent to treat OSC. METHODS: In this single-center case-controlled study comparing JAKi and corticosteroids in OSC cases, data of 41 cases out of 86 were included - 21 in the JAKi group and 20 in the corticosteroid group from 4 weeks of acute illness to the next 4 weeks. Clinical parameters and inflammatory markers were recorded. The primary outcome was to compare the proportion of patients who were able to maintain oxygen saturation ≥95% with any oxygen supplementation in the two groups. RESULTS: The baseline clinical and demographic characteristics were similar in the two groups. The age was 53.65 ± 9.8 years and 51.48 ± 14.0 years in the corticosteroid group and JAKi group, respectively. At the baseline, 85% of patients in the corticosteroid group and 85.8% in the JAKi group were on oxygen support. The most common symptom in both groups was breathlessness followed by cough. Twenty percent of patients in the JAKi group received baricitinib and the remaining were given tofacitinib. At the time of follow-up, the majority of cases had a significant reduction in C-reactive protein (CRP) and D-dimer; however, the change in CRP and D-dimer was similar in both groups. The number of patients off oxygen support at 4 weeks was higher in the JAKi group (85% in the corticosteroid group vs. 95.2% in the JAKi group, P = 0.269), and the median time to liberation from oxygen support was significantly lower in JAKi group (19 days in corticosteroid group vs. 9 days in JAKi group, P < 0.001). The frequency of any adverse event was also higher in the corticosteroid group (70% vs. 23.8%, P = 0.003). CONCLUSION: JAKi can be used as immunomodulatory drugs in hypoxic OSC cases having evidence of ongoing inflammation.

An Open-Label Non-Randomized Preliminary Noninferiority Study Comparing Home-Based Handheld Narrow-Band UVB Comb Device with Standard Hospital-Based Whole-Body Narrow-Band UVB Therapy in Localized Vitiligo.

Background: Narrow-band ultraviolet B (NB-UVB) is the standard therapy for vitiligo. Objective: The objective of this study is to compare the safety and clinical efficacy of a handheld NB-UVB comb device with the standard whole-body NB-UVB therapy in localized stable vitiligo. Materials and Methods: Thirty-one vitiligo patients were allocated to either daily therapy with a home-based handheld comb device (group A, n = 17) or thrice-weekly hospital-based whole-body NB-UVB therapy (group B, n = 14) for 4 months, based on their preference. The primary and secondary outcomes were assessed at each follow-up, and appropriate statistical tools were used for analysis. Results: Of the 31 patients enrolled, 26 patients (study groups A/B: 15/11) completed the study. Primary outcome: Median percentage repigmentation of the representative patch in groups A and B were 51.35% and 63.85%, respectively (P = 0.64). The median size reduction of the representative patch in both groups was statistically significant (P < 0.05). The mean difference between "per protocol analysis" and "intention to treat" showed noninferiority. Secondary outcomes: Both groups were comparable on Lund and Browder score, patient global assessment and investigator global assessment scores, adverse events, color match, and change in the quality of life. The comparison group had a significantly greater number of missed sessions (P = 0.02). The majority of patients had a "good" response in both groups. Conclusion: Handheld NB-UVB comb device daily with a fixed dose of fluence was found to be noninferior with better compliance to standard whole-body NB-UVB therapy.

Angiotensin Receptor-Neprilysin Inhibitor Therapy and Cardiac Remodeling in Heart Failure: Consensus Statement from India.

Adverse cardiac remodeling refers to progressive structural and functional modifications in the heart because of increased wall stress in the myocardium, loss of viable myocardium, and neurohormonal stimulation. The guideline-directed medical therapy for Heart failure (HF) includes Angiotensin receptor-neprilysin inhibitor (ARNI) (sacubitril/valsartan), ß-blockers, sodium-glucose co-transporter 2 (SGLT2) inhibitors, and mineralocorticoid receptor antagonists (MRA). ARNI is under-prescribed in India despite its attractive safety and efficacy profile. Therefore, the consensus discusses objectives and topics related to ARNI in the management of cardiac remodeling, and experts shared their views on the early timely intervention of effective dosage of ARNI to improve the diagnosis and enhance mortality and morbidity benefits in cardiac reverse remodeling (CRR).

The Power and Promise of Angiotensin Receptor Neprilysin Inhibitor (ARNI) in Heart Failure Management: National Consensus Statement.

;Heart failure (HF) is a huge global public health task due to morbidity, mortality, disturbed quality of life, and major economic burden. It is an area of active research and newer treatment strategies are evolving. Recently angiotensin receptor-neprilysin inhibitor (ARNI), a class of drugs (the first agent in this class, Sacubitril-Valsartan), reduces cardiovascular mortality and morbidity in chronic HF patients with reduced left ventricular ejection fraction (LVEF). Positive therapeutic effects have led to a decrease in cardiovascular mortality and HF hospitalizations (HFH), with a favorable safety profile, and have been documented in several clinical studies with an unquestionable survival benefit with ARNI, Sacubitril-Valsartan. This consensus statement of the Indian group of experts in cardiology, nephrology, and diabetes provides a comprehensive review of the power and promise of ARNI in HF management and an evidence-based appraisal of the use of ARNI as an essential treatment strategy for HF patients in clinical practice. Consensus in this review favors an early utility of Sacubitril-Valsartan in patients with HF with reduced EF (HFrEF), regardless of the previous therapy being given. A lower rate of hospitalizations for HF with Sacubitril-Valsartan in HF patients with preserved EF who are phenotypically heterogeneous suggests possible benefits of ARNI in patients having 40-50% of LVEF, frequent subtle systolic dysfunction, and higher hospitalization risk.

Role of Iron Therapy in Heart Failure: A Consensus Statement from India.

Iron deficiency (ID) with or without anemia is frequently observed in patients with heart failure (HF). Uncorrected ID is associated with higher hospitalization and mortality in patients with acute HF (AHF) and chronic HF (CHF). Hence, in addition to chronic renal insufficiency, anemia, and diabetes, ID appears as a novel comorbidity and a treatment target of CHF. Intravenous (IV) ferric carboxymaltose (FCM) reduces the hospitalization risk due to HF worsening and improves functional capacity and quality of life (QOL) in HF patients. The current consensus document provides criteria, an expert opinion on the diagnosis of ID in HF, patient profiles for IV FCM, and correct administration and monitoring of such patients.

Utility and timing of the respiratory rate-oxygenation index in the prediction of high-flow oxygen therapy failure in acute hypoxemic respiratory failure of infective etiology: a prospective observational study.

During and following the COVID-19 pandemic, the world has witnessed a surge in high-flow oxygen therapy (HFOT) use. The ability to provide high oxygenation levels with remarkable comfort levels has been the grounds for the same. Despite the advantages, delays in intubation leading to poor overall outcomes have been noticed in subgroups of patients on HFOT. The respiratory rate-oxygenation (ROX) index has been proposed to be a useful indicator to predict HFOT success. In this study, we have examined the utility of the ROX index prospectively in cases of acute hypoxemic respiratory failure (AHRF) due to infective etiologies. A total of 70 participants were screened, and 55 were recruited for the study. The majority of participants were males (56.4%), with diabetes mellitus being the most common comorbidity (29.1%). The mean age of the study subjects was 46.27±15.6 years. COVID-19 (70.9%) was the most common etiology for AHRF, followed by scrub typhus (21.8%). 19 (34.5%) experienced HFOT failure, and 9 (16.4%) subjects died during the study period. Demographic characteristics did not differ between either of the two groups (HFOT success versus failure and survived group versus expired group). The ROX index was significantly different between the HFOT success versus failure group at baseline, 2, 4, 6, 12, and 24 hours. The best cut-offs of the ROX index at baseline and 2 hours were 4.4 (sensitivity 91.7%, specificity 86.7%) and 4.3 (sensitivity 94.4% and specificity 86.7%), respectively. The ROX index was found to be an efficient tool in predicting HFOT failure in cases of AHRF with infective etiology.

Oral Propranolol Therapy for Infantile Hemangioma: Long-term Follow-up.

ß-blocker therapy is currently the treatment of choice for infantile hemangiomas (IH), albeit with limited data on long-term treatment outcomes. Herein, authors treated 67 IH lesions in 47 patients with oral propranolol at 2 mg/kg/d for a median of 9 mo and followed them up for a median of 48 mo. While no maintenance therapy was required for 18 lesions (26.9%), the rest needed maintenance therapy. Both treatment regimens had comparable efficacy (83.3±23.9% and 92.0±13.8%) but chances of IH recurrence was higher in lesions requiring maintenance therapy. Also, patients treated at ≤5 mo of age had a significantly better response and a lower recurrence rate than patients treated at >5 mo of age (95.0±7.9% vs. 87.0±17.5%, p = 0.05). Authors' experience suggests that longer durations of maintenance therapy offered no added advantage to the overall improvement of IH while treatment initiation at an earlier age showed better improvement and lower recurrence rates.

The Role of Genetic Testing in Children Requiring Surgery for Ectopia Lentis.

Non-traumatic ectopia lentis can be isolated or herald an underlying multisystemic disorder. Technological advances have revolutionized genetic testing for many ophthalmic disorders, and this study aims to provide insights into the clinical utility of genetic analysis in paediatric ectopia lentis. Children that underwent lens extraction for ectopia lentis between 2013 and 2017 were identified, and gene panel testing findings and surgical outcomes were collected. Overall, 10/11 cases received a probable molecular diagnosis. Genetic variants were identified in four genes: FBN1 (associated with Marfan syndrome and cardiovascular complications; n = 6), ADAMTSL4 (associated with non-syndromic ectopia lentis; n = 2), LTBP2 (n = 1) and ASPH (n = 1). Parents appeared unaffected in 6/11 cases; the initial presentation of all six of these children was to an ophthalmologist, and only 2/6 had FBN1 variants. Notably, 4/11 cases required surgery before the age of 4 years, and only one of these children carried an FBN1 variant. In summary, in this retrospective cohort study, panel-based genetic testing pointed to a molecular diagnosis in >90% of paediatric ectopia lentis cases requiring surgery. In a subset of study participants, genetic analysis revealed changes in genes that have not been linked to extraocular manifestations and highlighted that extensive systemic investigations were not required in these individuals. We propose the introduction of genetic testing early in the diagnostic pathway in children with ectopia lentis.

Comparison of Clinical and Functional Outcomes after Platelet-Rich Plasma Injection and Corticosteroid Injection for the Treatment of de Quervain's Tenosynovitis.

Background Platelet-rich plasma (PRP) has local anti-inflammatory actions, which is being used as a treatment in various tendinopathies. Purpose The aim of the study is to compare the clinical results of PRP injection and corticosteroid injection in the management of de Quervain's tenosynovitis (DQTSV). Patients and Methods In this prospective study, 60 patients of DQTSV, fulfilling the predefined inclusion and exclusion criteria, were randomised into two groups. In group 1 ( n = 30), patients received a single injection of autologous PRP and in group 2 ( n = 30) they received a single injection of corticosteroid (methylprednisolone). All patients were followed up at 1 month, 3 months, 6 months, and 1 year for evaluation by Finkelstein test, visual analogue scale (VAS), DASH (Disabilities of the Arm, Shoulder and Hand) score, and Modified Mayo Wrist score (MMWS). Results In both the groups improvement occurred in Finkelstein test, VAS score, DASH score, and MMWS which were found to be statistically significant at all points of follow-ups when compared to the pre-intervention values. Comparison of scores between the two groups did not show any statistical significance. No complications were reported in PRP group. Statistically significant complications ( p -value = 0.026) like subcutaneous fat atrophy, depigmentation, and temporary increase in pain were seen in eight patients in the corticosteroid group with an overall complication rate of 26.67%. Conclusion Both the modalities are equally effective in the management of DQTSV remittance. PRP is equally effective as corticosteroid in reducing symptoms of first dorsal compartment stenosing tenosynovitis. PRP may have a lower complication profile, however, this benefit should be weighed against the slight increase in cost and time of PRP preparation and injection. Level of Evidence Level 2, prospective comparative study.

Copper(ii) and cobalt(iii) Schiff base complexes with hydroxy anchors as sensitizers in dye-sensitized solar cells (DSSCs).

Two Schiff base complexes of copper(ii) and cobalt(iii) having the formulae [CuL2] (Cu-Sal) and [CoL3] (Co-Sal) (HL = 2-(((2-hydroxyethyl)imino)methyl)phenol) have been synthesized and characterized microanalytically, spectroscopically and in the case of Cu-Sal using single crystal X-ray diffraction technique. The single crystal X-ray analysis reveals a square planar geometry around Cu(ii) satisfied by phenoxide oxygen and imine nitrogen of the L- ligand to generate a six membered chelate ring. The solid state structure of Cu-Sal is satisfied by varied intermolecular non-covalent interactions. The nature of these interactions has been addressed with the aid of Hirshfeld surface analysis. Both compounds have been used as sensitizers in TiO2 based dye sensitized solar cells (DSSCs) and the DSSC experiments revealed that Co-Sal offers better photovoltaic performance in comparison to Cu-Sal. The Co-Sal exhibited a J sc of 9.75 mA cm-2 with a V oc of -0.648 V, incident photon to current conversion efficiency (IPCE) of 57% and η of 3.84%. The relatively better photovoltaic performance of Co-Sal could be attributed to better light absorption and dye loading than that of Cu-Sal.
