Abstract
Purpose
This paper aims to study the physical and chemical characteristics of inkjet titanium dioxide inks for cotton fabric digital printing.
Design/methodology/approach
Different dispersing agents through the reaction of glycerol monooleate and toluene diisocyanate were prepared and then performed by using three different polyols (succinic anhydride-modified polyethylene glycol PEG 600, EO/PO Polyether Monoamine and p-chloro aniline Polyether Monoamine), to obtain three different dispersing agents for water-based titanium dioxide inkjet inks. The prepared dispersants were characterized using FTIR to monitor the reaction progress. Then the prepared dispersants were formulated in titanium dioxide inkjet inks formulation and characterized by particle size, dynamic surface tension, transmission electron microscopy, viscosity and zeta potential against commercial dispersants. Also, the study was extended to evaluate the printed polyester by using the prepared inks according to washing and crock fastness.
Findings
The obtained results showed that p-chloro aniline Polyether Monoamine (J) and succinic anhydride modified polyethylene glycol PEG 600 (H) dispersants provided optimum performance as compared to commercial standards especially, particle size distribution data while EO/PO Polyether Monoamine based on dispersant was against and then failed with the wettability and dispersion stability tests.
Practical implications
These ink formulations could be used for printing on cotton fabric by DTG technique of printing and can be used for other types of fabrics.
Originality/value
The newly prepared ink formulation for digital textile printing based on synthesized polyurethane prepolymers has the potential to be promising in this type of printing inks, to prevent clogging of nozzles on the printhead and to improve the print quality on the textile fiber.

Abstract
Background There has been significant international interest in heterologous prime-boost COVID-19 vaccination. However, it is linked with different intensity and frequency of adverse events. This study aimed to assess the safety of ChAdOx1-S and BNT162b2 vaccines when given as heterologous prime-boost vaccination in Saudi Arabia. Methods A cross-sectional study was conducted during the period October 2021 to March 2022. The study included two groups of people based on the type of vaccination regimen. The first group (heterologous) was subjected to different prime-boost vaccination schedules irrespective of the prime and boost vaccine types. The second group included people vaccinated with the same type of COVID-19 vaccine (homologous). Results The overall sample included 334 participants. Those included in the heterologous group were at about 1.5 fold -increased risk for developing local and systemic adverse events compared to the homologous group. Fever, headache, and vomiting were significantly more frequent among the heterologous group compared to the homologous group (p-value<0.05). In both groups, more than half of the recorded adverse events were mild/moderate in severity. Conclusion Heterologous prime-post vaccination is associated with a slightly increased risk for the development of local and systemic adverse events compared to the homologous regimen. However, most of these adverse events are mild/moderate in nature and recede within two days with no serious adverse events documented.

Abstract
BACKGROUND Calciphylaxis is a life-threatening cutaneous ulcerative/necrotic disease characterized by vascular calcification/occlusion. It occurs most commonly in end-stage kidney disease (ESKD), known as uraemic calciphylaxis (UC) but can also occur in patients with chronic kidney disease (CKD) and normal kidney function (nonuraemic calciphylaxis; NUC). There are few large series of NUC in the literature. AIM To compare the clinicopathological features of UC and NUC. METHODS We retrospectively compared the clinicopathological features of 35 patients with NUC during the period 2010-2020 with those of 53 patients with UC (control group). Cases were classified as NUC in the absence of all of the following: ESKD, significant CKD (defined as serum creatinine > 3 mg/dL or creatinine clearance < 15 mL/min) and acute kidney injury requiring kidney replacement therapy or kidney transplantation. RESULTS NUC represented 40% of the total cases, and there was a higher number of women (P < 0.01) and a higher median body mass index (P = 0.06) compared with the control UC group. Elevated parathyroid hormone was present in 44% of patients with NUC. Most of the tested patients were positive for lupus anticoagulants (56%). NUC biopsies showed a higher rate of extravascular calcium deposits (73% vs. 47%, P = 0.03). Dermal reactive vascular proliferation was the most common dermal change (32%). CONCLUSIONS NUC is more common than previously reported and shows a higher predilection for obese postmenopausal women. Undiagnosed hyperparathyroidism shows a possible association with NUC. Lupus anticoagulants were positive in most patients. NUC biopsies are more likely than UC biopsies to display extravascular calcium deposition.

Abstract
Background Saudi Arabia embarked on transforming its primary health care system in 2016 to meet international standards, gain the people's trust and respond to the growing burden of noncommunicable diseases, as proposed in the Saudi Vision 2030. Aims This review aims to highlight the progress, identify challenges and prospects for Saudi Arabia's PHC reform process in order to make recommendations to facilitate strengthening of the PHC system. Methods A review of previous studies and governmental reports was undertaken to extract, analyse, synthesize and report the findings. Results The review has indicated that by mid-2019, the reform has contributed to an increase of 37.5% in the rate of PHC visits and 4.7% increase in patient satisfaction, enhanced coverage of rural communities (from 78% to 83%), and contributed to increasing the screening rate for prevalent chronic diseases. However, the country still faces gaps and challenges pertaining to human resources issues, cultural and lifestyle behaviour, geography, intersectoral collaboration and PHC infrastructure. Conclusion PHC reform process in Saudi Arabia has demonstrated that positive change is achievable. This has been aided by building on previous accomplishments and the wealth of experience gained throughout the PHC journey in Saudi Arabia. However, despite improvement in the quality of services, continuous improvement is required to meet the rising expectations of the population.

Abstract
Abstract
Background
Heart failure with preserved ejection fraction (HFpEF) represents more than one half of the heart failure cases worldwide with increased morbidity and mortality. No proven medical treatment till now have shown mortality benefit in HFpEF. This study aims to elucidate the benefits of cardiac rehabilitation (CR) in HFpEF.
Methods
Sixty patients with HFpEF were included in 2 groups with 1:1 randomization.Group1 received usual medical care plus 2–3 rehabilitation sessions per week using moderate exercise with 40–75% of heart rate reserve on treadmill (up to 60 minutes according to the functional capacity). Group 2 received only usual medical care. Comparison between the 2 groups recording the percentage of improvement in echocardiographic diastolic function parameters, Minnesota living with heart failure questionnaire (MLWHFQ) and 6 -minute walk test at baseline and after 12 weeks.
Results
Group 1 showed significant improvement in the following: a. MLWHFQ (total score mean percentage of reduction) 305.60±158.44 versus (vs) 69.44±17.71 (p<0.001).b. E/e' mean percentage of reduction 65.96±34.55 vs 18.23±13.98 (p<0.001). c. Left atrial (LA) volume index mean percentage of reduction 27.86±13.27 vs 8.03±4.40 (p<0.001). d. Pulmonary artery systolic pressure mean percentage of reduction was 33.85±14.68 vs 22.97±16.54 (p=0.02). e. 6–minute walk test 111.79±40.97 vs 46.33±11.58 (p<0.001). f. Body mass index percentage of reduction 10.17±3.64 vs 2.80±1.60 (p<0.001). g. Percentage of patients with down-grading of the degree of diastolic dysfunction: 10 patients (33.3%) vs 3 patients (10%) (P=0.028). h. However, there were no significant differences in left ventricular ejection fraction or other parameters as E/A ratio, LA dimension, isovolumetric relaxation time, degree of left ventricular hypertrophy.
Conclusion
CR not only added significant functional improvement in the quality of life and functional capacity in patients with HFpEF but also a significant structural improvement by improving the core items of diastolic function. In the light of the results of this study, we can recommend CR as a part of HFpEF management.

Abstract
Purpose
This paper aims to study the effect of the new modified dispersing agent, milling time of the properties and particle size distribution (PSD) of inkjet ink formulation for polyester fabric printing.
Design/methodology/approach
The study’s methods include preparation of different formulations of textile inkjet inks based on different types of dispersing agents, then applying and evaluating the prepared formulations on the polyester fabric. The properties of the prepared ink formulations were analyzed by measuring viscosity, surface tension and particle size. The current work is including the study of the effect of using different doses of different dispersing agents and the milling time on their characteristics. Also, the study was extended to evaluate the printed polyester by using the prepared inks according to light fastness, washing fastness, alkali perspiration fastness and crock fastness.
Findings
The results showed that the used dispersing agents and the different milling time enhanced the viscosity and dynamic surface tension in the accepted range, but it was largely cleared in the PSD which tends to perform the inks on the printhead and prevent clogging of nozzles. Light fastness, washing fastness, alkali perspiration fastness and crock fastness gave good results in agreement with this type of inkjet inks for textile printing.
Research limitations/implications
In this work, good results were obtained with this type of dispersing agent for inkjet ink formulations, but for other dispersing agents, other tests could be performed. The inkjet ink could also be formulated with other additives to prevent clogging of nozzles on the printhead.
Practical implications
These ink formulations could be used for printing on polyester fabric by the inkjet printing.
Originality/value
Recently, there was a considerable interest in the study of the effect of PSD on the inkjet inks to prevent clogging of nozzles on the printhead and to improve the print quality on the textile fiber.

Abstract
Abstract
Background
The pathogenic role of ischemic heart disease (IHD) in heart failure is well known. However, little is known about the global differences in the prognostic significance and treatment patterns of IHD in acute heart failure (AHF).
Methods
We prospectively enrolled 18,553 patients with AHF from 44 countries and 365 centers in the REPORT-HF registry. Patients with a history of coronary artery disease, an ischemic etiology of the AHF event or coronary revascularization were classified as IHD. Differences in clinical characteristics, treatment and outcome were analyzed.
Results
Compared to 9,344 (50%) patients without IHD, the 9,189 (50%) patients with IHD were older, more often had a left ventricular ejection fraction [LVEF] <40%, (HFrEF) and decompensated chronic HF (DCHF) and had a greater comorbidity burden. Despite patients from lower-income countries having a higher prevalence of IHD (55% vs. 45% in high-income countries), only 27% of patients with IHD from low-income countries were treated with medicines commonly prescribed for HF (Figure A) compared to 16% of patients with IHD from high income countries. After correction for clinical confounders and medication use, patients with IHD had a shorter “door-to-nitrates and -diuretics time” and worse 1-year mortality (hazard ratio: 1.18, 95% CI: 1.09, 1.27, Figure B) irrespective of geographic region (Pinteraction >0.1). We found a significant interaction for prognosis (Pinteraction <0.001) between IHD and HF diagnosis (DCHF vs. new-onset HF) as well as HF subtype (HFrEF vs. HF with preserved ejection fraction) respectively, such that IHD conveyed worse outcomes in patients with new-onset HF and HFrEF respectively in all world regions.
Conclusion
In this large global contemporary cohort of patients with AHF, IHD was more common in patients from low income countries, conveyed worse 1-year mortality, particularly in patients with new onset HF and patients with HFrEF. Despite worse outcomes, patients in regions with the greatest burden of IHD were more often undertreated.

Abstract
Background Global healthcare is challenged following the COVID-19 pandemic, since late 2019. Multiple approaches have been performed to relieve the pressure and support existing healthcare. The Saudi Arabian Ministry of Health (MOH) launched an initiative to support the National Healthcare System. Since the 5th of June 2020, 238 outpatient fever clinics were established nationwide. This study aimed to assess the safety outcome and reported adverse events from hydroxychloroquine use among suspected COVID-19 patients. Method A cross-sectional study included 2,733 patients subjected to MOH treatment protocol (hydroxychloroquine) and followed-up within 3-7 days after initiation. Data was collected through an electronic link and cross-checked with the national database (Health Electronic Surveillance Network, HESN) and reports from the MOH Morbidity and Mortality (M&M) Committee. Results 240 patients (8.8%) discontinued treatment because of side effects (4.1%) and for non-clinical reasons in the remaining (4.7%). Adverse effects were reported among (6.7%) of all studied participants, including mainly cardiovascular (2.5%, 0.15% with QTc prolongation), and gastrointestinal (2.4%). No Intensive Care Unit admission or death were reported among these patients. Conclusion Our results show that hydroxychloroquine for COVID-19 patients in mild to moderate cases in an outpatient setting, within the protocol recommendation and inclusion/exclusion criteria, is safe, highly tolerable, and with minimum side effects.

Abstract
AIMS The major aims of this study are to determine the capability of sulphur oxidizing bacterium (SOB-1) to desulphurize dibenzothiophene (DBT) and crude oil, detection of the reaction kinetics and identify the proposed pathway of DBT desulphurization. METHODS AND RESULTS The isolate was genetically identified based on 16S rRNA gene sequencing as Klebsiella oxytoca and deposited in the Genebank database under the accession number: MT355440. The HPLC analysis of the remaining DBT concentration revealed that, SOB-1 could desulphurize 90% of DBT (0·25 mmol l-1 ) within 96 h. The maximum production of sulphate ions from the desulphurization of DBT (0·36 mmol l-1 ) and crude oil (0·4 mmol l-1 ) could be quantitatively detected after 48 h of incubation at 30°C. The high values of correlation coefficient (R2 ) obtained at all studied concentrations; suggested that biodesulfurization kinetics of DBT follows the first-order reaction model. The kinetics studies showed that, DBT may have an inhibitory effect on SOB-1 when the initial concentration exceeded 0·75 mmol l-1 . The GC-MS analysis exhibited four main metabolites rather than DBT. The most important ones are 2-hydroxybiphenyl (2-HBP) and methoxybiphenyl n(2-MBP). CONCLUSIONS Klebsiella oxytoca SOB-1 catalyzes the desulphurization of DBT through 4S pathway and forms four main metabolic products. The release of sulphate ion and formation of 2-HBP indicating the elimination of sulphur group without altering the carbon skeleton of DBT. The bacterial strain could also catalyzes desulphurization of crude oil. The desulphurization kinetics follows the first-order reaction model. SIGNIFICANCE AND IMPACT OF THE STUDY Klebsiella oxytoca SOB-1 could be used as a promising industrial and environmental biodesulfurizing agent as it is not affecting carbon skeleton of thiophenic compounds and forming less toxic metabolic product (2-MBP).

Abstract
The COVID-19 pandemic has added an enormous toll to the existing challenge of diabetes care world-wide. A large proportion of patients with COVID-19 requiring hospitalization and/or succumbing to the disease have had diabetes and other chronic conditions as underlying risk factors. In particular, individuals belonging to racial/ethnic minorities in the U.S. and other countries have been significantly and disproportionately impacted. Multiple and complex socioeconomic factors have long played a role in increasing the risk for diabetes and now for COVID-19. Since the pandemic began, the global healthcare community has accumulated invaluable clinical experience on providing diabetes care in the setting of COVID-19. In addition, understanding of the pathophysiological mechanisms that link these two diseases is being developed. The current clinical management of diabetes is a work in progress, requiring a shift in patient-provider interaction beyond the walls of clinics and hospitals: the use of tele-medicine when feasible, innovative patient education programs, strategies to ensure medication and glucose testing availability and affordability, as well as numerous ideas on how to improve meal plans and physical activity. Notably, this worldwide experience offers us the possibility to not only prepare better for future disasters but also transform diabetes care beyond the COVID-19 era.

Abstract
The month of Ramadan forms one of the five pillars of the Muslim faith. Adult Muslims are obligated to keep daily fasts from dawn to sunset, with exceptions. This year Ramadan is due to begin on 23 April 2020 and the longest fast in the UK will be approximately 18 hours in length. In addition, due to the often high-calorie meals eaten to break the fast, Ramadan should be seen as a cycle of fasting and feasting. Ramadan fasting can impact those with diabetes, increasing the risk of hypoglycaemia, hyperglycaemia and dehydration. This year, Ramadan will occur during the global COVID-19 pandemic. Reports show that diabetes appears to be a risk factor for more severe disease with COVID-19. In addition, the UK experience has shown diabetes and COVID-19 is associated with dehydration, starvation ketosis, diabetic ketoacidosis and hyperosmolar hyperglycaemic state. This makes fasting in Ramadan particularly challenging for those Muslims with diabetes. Here, we discuss the implications of fasting in Ramadan during the COVID-19 pandemic and make recommendations for those with diabetes who wish to fast.

Abstract
BACKGROUND Fasting in the holy month of Ramadan is among the five pillars of Islam and is considered as a religious obligation by the Muslim population. People with diabetes observing the practice of fasts are at a higher risk of complications such as hypoglycaemia, hyperglycaemia and ketoacidosis due to changes in eating patterns and circadian rhythms. With the objective of mitigating these complications, the South Asian Health Foundation (UK) has developed the present guidelines based on robust evidence derived from epidemiological studies and clinical trials. METHODS We have highlighted the role of pre-Ramadan risk stratification and counselling by healthcare professionals with emphasis on the need for advice on adequate dietary and fluid intake, blood glucose monitoring and awareness of when to break the fast. RESULTS We reviewed the current literature and have given clinically-relevant recommendations on lifestyle modifications and glucose-lowering therapies such as metformin, sulphonylureas, dipeptidyl peptidase-4 inhibitors, sodium glucose co-transporter-2 inhibitors, thiazolidinediones, glucagon-like peptide-1 receptor agonists and insulin. CONCLUSIONS An individualised patient-centric treatment plan is essential to not only achieve optimal glycaemic outcomes but also enable people with diabetes to observe a risk-free month of fasting during Ramadan.

Abstract
AIM To describe the characteristics and management of patients with diabetes who chose to fast during Ramadan in 2010. METHODS This was a multi-country, retrospective, observational study, supplemented with physician and patient questionnaires, with data captured before, during and after Ramadan. A total of 508 physicians in 13 countries enrolled 3777 patients and a total of 3394 evaluable cases were analysed. We report on the subset of patients with Type 2 diabetes, which included 3250 patients (95.8%). RESULTS Oral anti-hyperglycaemic therapy was the predominant pre-Ramadan therapy for most patients (76.6%). The treatment regimen was modified before Ramadan for 39.3% of all patients (34.9% for patients on oral drugs alone, 47.1% for patients on injectable drugs alone). Almost all physicians (96.2%) reported providing fasting-specific advice to patients and 62.6% report using guidelines or recommendations for the management of diabetes during Ramadan. In all, 64% of patients reported fasting everyday of Ramadan and 94.2% fasted for at least 15 days. CONCLUSIONS Physicians have increasingly adopted multiple approaches to the management of fasting during Ramadan, including the adoption of international and/or national guidelines, providing fasting-specific advice and adjusting treatment regimens, such that patients are able to fast for a greater number of days without acute complications. Additional research is needed to explore physician and patient beliefs and practices to inform the evidence-based management of diabetes while fasting, both during and outside of Ramadan, and to identify and address barriers to the universal uptake of techniques to facilitate that management.

Abstract
OBJECTIVE To assess treatment adherence to dipeptidyl peptidase-4 inhibitor vildagliptin compared with sulphonylureas (SU) in Muslim patients with type 2 diabetes mellitus who were fasting during Ramadan in the UK. RESEARCH DESIGN AND METHODS This prospective, observational cohort study was conducted in four UK centres. Patients already taking vildagliptin (50 mg twice a day) or an SU as add-on therapy to metformin were followed up for ≤16 weeks. They were asked to record all missed doses of anti-diabetes medications. RESULTS Of the 72 patients enrolled (vildagliptin, n = 30; SU, n = 41; not allocated to treatment, n = 1), 59 (81.9%) completed the study (vildagliptin, n = 23; SU, n = 36), including one patient in the SU arm who completed but failed to provide information on missed doses; all patients in the SU arm were taking gliclazide. In the vildagliptin arm one patient (4.3%) missed a total of four doses while in the SU arm 10 patients (27.8%) missed a total of 266 doses (mean [SD] number of doses missed per patient: 26.6 [16.5]). The mean (SD) proportions of doses missed during fasting were 0.2% (0.9) and 10.4% (21.7) in the vildagliptin and SU arms, respectively, with a significant mean between-group difference of -10.2% (95% CI: -19.3%, -1.1%; p = 0.0292). There were no patients in the vildagliptin arm who missed more than 20% of OAD doses compared with 19.4% in the SU arm (p = 0.0358). Of the patients receiving an SU, 15 (42%) collectively reported 34 hypoglycaemic events (HEs) and one grade 2 HE; of these, fewer were non-adherent (n = 6, 40%) than adherent (n = 9, 60%). No patients reported HEs in the vildagliptin arm. CONCLUSION During Ramadan fasting, treatment with vildagliptin resulted in better treatment adherence compared with SU in Muslim patients with type 2 diabetes mellitus. Study limitations are the sample size and the lack of diet and exercise data.

Abstract
AIMS To compare hypoglycaemic events, glycated haemoglobin (HbA1c) and changes in body weight in Muslim patients with Type 2 diabetes receiving Humalog Mix 50 and human Mixtard 30 twice daily during Ramadan fasting. METHODS Data were collected from Muslim patients with Type 2 diabetes attending primary care practices in North-West London, who were on Mixtard 30 insulin twice daily before Ramadan. Group 1 had their evening insulin changed to Humalog Mix 50 (n = 26) 2 weeks before Ramadan, i.e. taking Mixtard 30 at predawn meal and Humalog Mix 50 at the sunset meal during Ramadan. As the major proportion of the daily caloric intake was consumed at the sunset meal, the rationale of switching the evening dose from human Mixtard 30 to Humalog Mix 50 was to provide more rapid-acting insulin that has shorter time of onset and peak time for the large evening meal to improve the postprandial glucose control without increasing the risk of hypoglycaemia. Group 2 continued on Mixtard 30 twice daily (n = 26). All patients received structured education about how to identify and manage hypoglycaemia during Ramadan. RESULTS Group 1 had a mean HbA1c reduction of 0.48% (p = 0.0001) before and after Ramadan, whereas group 2 had a mean HbA1c increase of 0.28% (p = 0.007). Group 1 was associated with a small reduction of 0.04 (p = 0.81) in the mean number of hypoglycaemic events during Ramadan compared with before Ramadan, whereas group 2 was associated with an increase of 0.15 (p = 0.43), although these differences between the groups were not statistically significant following adjustment for baseline factors [LSM difference between groups = 0.135, p = 0.36, 95% confidence limits (-0.16, 0.43)]. CONCLUSION Changing to humalog Mix 50 during Ramadan resulted in improvement in glycaemic control without increasing the incidence of hypoglycaemia.

Abstract
BACKGROUND AND AIMS During Ramadan, Muslims fast from dawn to dusk for one lunar month. The majority of Muslim diabetic patients are unaware of complications such as hypoglycaemia during fasting. The safety of fasting has not been assessed in the UK Muslim population with diabetes. The aim of this study was to determine the impact of Ramadan-focused education on weight and hypoglycaemic episodes during Ramadan in a Type 2 diabetic Muslim population taking oral glucose-lowering agents. METHODS We retrospectively analysed two groups. Group A attended a structured education programme about physical activity, meal planning, glucose monitoring, hypoglycaemia, dosage and timing of medications. Group B did not. Hypoglycaemia was defined as home blood glucose < 3.5 mmol/l. RESULTS There was a mean weight loss of 0.7 kg after Ramadan in group A, compared with a 0.6-kg mean weight gain in group B (P < 0.001). The weight changes observed were independent of the class of glucose-lowering agents used. There was a significant decrease in the total number of hypoglycaemic events in group A, from nine to five, compared with an increase in group B from nine to 36 (P < 0.001). The majority were in patients treated with short-acting sulphonylureas (group A-100%, group B-94%). At 12 months after attending the programme, glycated haemoglobin (HbA(1c)) reduction were sustained in group A. CONCLUSIONS Ramadan-focused education in diabetes can empower patients to change their lifestyle during Ramadan. It minimizes the risk of hypoglycaemic events and prevents weight gain during this festive period for Muslims, which potentially benefits metabolic control.

Abstract
AIMS To compare hypoglycaemic events, glycated haemoglobin (HbA(1c)) and changes in bodyweight in metformin-treated Muslim patients with type 2 diabetes receiving adjunctive treatment with vildagliptin or gliclazide during Ramadan fasting. METHODS Data were collected from Muslim patients with type 2 diabetes attending primary care practices in North West London, whose HbA(1c) was > 8.5% despite treatment with metformin 2 g daily before Ramadan and who received gliclazide 160 mg twice daily (n = 26) or vildagliptin 50 mg twice daily (n = 26) in addition to metformin. Hypoglycaemic events, HbA(1c) and weight were recorded 2 weeks before and 10 days after the Ramadan fast. All patients received education about how to identify and manage hypoglycaemia during Ramadan. RESULTS During Ramadan, at least one hypoglycaemic event (defined as blood glucose < 3.5 mmol/l with or without symptoms) was recorded in two patients receiving vildagliptin (7.7%) and 16 patients receiving gliclazide [61.5%; difference between groups -53.8%, 95% confidence interval (CI) -74.9 to -26.3, p < 0.001]. Vildagliptin was associated with a reduction in the mean number of hypoglycaemic events during Ramadan compared with before Ramadan, whereas gliclazide was associated with an increase (least squares mean difference between groups -0.66, 95% CI -1.20 to -0.13, p = 0.0168). Both gliclazide and vildagliptin were associated with similar reductions in HbA(1c) and a small, but insignificant, increase in weight. CONCLUSIONS Appropriate treatment adjustments can lead to improved diabetes management during Ramadan, with avoidance of significant weight gain and improved glucose control without hypoglycaemia. The addition of vildagliptin to metformin therapy during Ramadan in Muslim patients with type 2 diabetes was associated with a reduction in the incidence of hypoglycaemia.

Abstract
Cathepsin P is a member of a family of placentally expressed cathepsins (PECs). The closest human homolog of cathepsin P is cathepsin L, a broad specificity enzyme that has functions in many tissues in addition to placenta. The gene duplications that gave rise to the PECs provide a rare opportunity to define proteolytic functions in placenta, a transient organ unique to mammals. Peptidyl substrate and inhibitor libraries have shown that cathepsin P has evolved an unusually restricted preference for substrates containing hydrophobic amino acids. Proteomic techniques were used to probe for substrates of this enzyme. Recombinant cathepsin P was incubated with rat choriocarcinoma (Rcho-1) cell proteins to identify substrates using two-dimensional difference gel electrophoresis. Substrate proteins were excised from gels and characterized by trypsin digestion and MALDI MS/MS. Two endoplasmic reticulum (ER) proteins, gp96 and calreticulin, emerged as potential substrates, and western blotting showed that these proteins are processed by cathepsin P from their C-terminus, removing the KDEL ER retention signal. Immunohistochemistry showed that a portion of cathepsin P co-localizes with calreticulin in Rcho-1 cells. Extracellular calreticulin induces differentiation of Rcho-1 cells, indicating a potential role of cathepsin P in processing and secretion of calreticulin during differentiation of trophoblast giant cells.

Abstract
Lysosomal proteases perform critical functions in protein turnover and are essential for normal growth and development. Cathepsin P is a member of a newly discovered family of lysosomal cysteine proteases uniquely expressed in rodent placenta (PECs), and is closely related to human cathepsin L. Using the rat choriocarcinoma cell line model, Rcho-1, mRNA for the PECs cathepsins P, M, Q, R, 1, 2 was found to increase in expression during differentiation into a trophoblast giant cell phenotype. By contrast, expression of cathepsin L was not regulated. A specific enzyme assay was developed to show that activity of cathepsin P mirrored mRNA expression during differentiation. Cathepsin P protein co-localizes with cathepsin B, indicating that the enzyme probably functions in the endosomal-lysosomal compartment. This study demonstrates that the PEC genes produce functional proteases that can perform specific placental roles that are probably performed by broader specificity proteases in human placenta.
