ABSTRACT
Background: Osteoarthritis (OA) is a complex joint degenerative disorder. Pain is a dominant characteristic, becoming persistent and more limiting as the disease progresses, resulting in reduced physical function, quality-of-life. Magnesium deficiency is considered to be a major risk factor for osteoarthritis development and progression. Oral magnesium presents unique challenges for many individuals to effectively restore intracellular magnesium levels. Transdermal magnesium absorption could be more effective than oral absorption due to its greater absorption rate and presents fewer negative effects due to its gastrointestinal tract-bypassing nature. Method: Total 40 subjects with knee osteoarthritis were selected as per the inclusion and exclusion criteria and randomly assigned to either Group A (intervention) or Group B (conventional), each having 20 patients. Assessment of the outcome measures was done pre and post 8 sessions. Outcome measures used were Visual Analogue Scale (VAS), Western Ontario and McMaster Universities Arthritis Index (WOMAC), Timed up and go test (TUG), 9 Step stair climb test, Knee ROM, Quadriceps strength using pressure biofeedback. Group A was given conventional therapy along with Epsom salt foot soak and Magnesium oil application. Group B was given conventional therapy alone. Result: There was statistically significant improvement seen in all the outcome measures in intragroup analysis with p<0.05. Intergroup analysis showed statistically significant difference in VAS on activity, WOMAC, Knee ROM, Quadriceps strength with p <0.05 indicating Group A performed better than Group B.Conclusion: The study found that Magnesium when used as an adjunct to conventional therapy shows significant difference in pain levels, knee mobility, quadriceps strength and better functionality in activities of daily living.
ABSTRACT
Mixed connective tissue disease (MCTD) as an autoimmune disorder with characteristics that resemble systemic sclerosis, systemic lupus erythematosus (SLE), and polymyositis. Due to this overlap, MCTD is often categorized as an overlap disease. As the disease progresses, symptoms may become more indicative of one of the three primary illnesses, accompanied by elevated levels of anti-U1RNP antibody. 30yrs female Patient presented with a classical malar rash as the initial presentation, followed by the development of a painful red lesion on the knuckles over a few weeks. Additionally, the patient observed a hypopigmented large lesion on the forearm resembling vitiligo, with a salt and pepper appearance. Upon clinical evaluation and further extensive investigation, the patient was diagnosed with mixed connective tissue disease (MCTD). On further evaluation the anti-U1RNP antibody, ANA, was positive and patient was treated on lines of MCTD. Patient responded well to the treatment. Our case suggests that mixed connective tissue disease if recognised early with symptoms and signs and workup we can prevent the shift to other connective tissue diseases over a long period; therefore, it is necessary to identify whether patients with mixed connective tissue disease fulfil the diagnostic criteria for other connective tissue diseases when new manifestations appear.
ABSTRACT
Background: Hypertension is a commonest cardiovascular disorder and is major cause of premature death worldwide. An estimated 1.28 billion adults aged 30-79 years worldwide have hypertension, most (two-thirds) living in low and middle-income countries. So present study was undertaken to assess the risk factors for hypertension among First year MBBS students so that suitable preventive measures may be undertaken. Methods: It is cross sectional study conducted among first year MBBS students in DRKGMC Hamirpur. The duration of study is three months. The tools of study used were modified structured pretested self-administered questionnaire; WHO stepwise approach to chronic disease risk factor surveillance (STEPS). Weighing machine, measuring tape, digital BP apparatus and steadiometer. Results: A total of 115 students of MBBS first year participated in the study. There were a total of 31.3% (36) boys and 68.7% (79) girls. Thirty three percent (38) had a family history of hypertension. 16.52% (19) had a BMI more than the normal. Among the study participants only 5 students (4.35%) used to consume alcohol and smoke cigarettes. Most of study participants consume fast food and junk food. Conclusions: High prevalence of different modifiable risk factors for hypertension revealed among the study subjects.There is need to screen the modifiable risk factors from very early age.
ABSTRACT
Background: Use of iron fortified iodised salt (IS) for 12 months, resulted in improvement in haemoglobin (Hb) in women, children and men. There is no published data on impact of DFS use beyond 12 months on Hb levels. Methods: A community based open randomised study to assess impact of use of DFS on Hb was discontinued after 12 months due to COVID 19 related lockdown. These families used IS for six months during lockdown; they were willing to continue using the salt provided for further one year. These families were re-randomized into three groups and given the assigned salt for further 12 months and Hb, ferritin and C-reactive protein (CRP) were estimated at 12 months. Results: Improvement in the mean Hb was 0.5 g/dl in women who had used IS earlier and DFS under second randomisation and 0.3 g/dl in those who had used DFS under first and second randomisation. Mean Hb at 30 months was higher in those who had used DFS for 24 months as compared to those who had used IS for 18 months and DFS for 12 months. The deterioration in mean Hb following discontinuation of DFS for 6 and 18 months was small. Conclusions: DFS use for the second year resulted in a further increase in Hb in those who had used DFS earlier. The relatively small deterioration in mean Hb following discontinuation of DFS might at least be in part due to the impact of nutrition and health education and access to health and nutrition services.
ABSTRACT
Objective To understand the trends of the mortality and DALY of ischemic heart disease (IHD) caused by high-salt diets，as well as their age-period-cohort effects among Chinese residents from 1990 to 2019. Methods Using the 2019 Global Burden of Disease Study (GBD 2019) data on IHD deaths and DALY attributed to high-salt diets among Chinese residents from 1990 to 2019, an age-period-cohort (APC) model was applied to explore the age-period-cohort effect. Results Among the 13 major risk factors for ischemic heart disease (IHD) in China in 1990 and 2019, age-standardized mortality and age-standardized DALY rates attributable to risk factors of high-salt diets led the way. Age-standardized mortality and age-standardized DALY rates were attributabled to high-salt diets showed a decreasing trend in both China and globally in 1990-2019, but were consistently higher in China than in the world. The results of the APC model show that from 1990 to 2019, the mortality rate and DALY rate of IHD attributed to a high-salt diet in China showed an increasing trend with age; over time, the risk of death and the risk of DALY for males showed a decreasing trend from 1990-1994 to 1995-1999, and an increasing trend from 1995-1999 to 2010-2014, and reached its peak in 2010-2014 (RR=1.17,95% CI: 1.12-1.21), followed by a decreasing trend. For males with a later birth cohort have a higher risk of death and DALY, while for females with a later birth cohort have a lower risk of death and DALY. Conclusion The burden of IHD disease attributed to a high-salt diet in China is still relatively heavy, and it is necessary to strengthen protection for high-risk populations such as young males and the elderly population to reduce the burden of IHD disease in China.
ABSTRACT
BACKGROUND:Aging is an irreversible process that is characterized by genes,diet and environment.As a central regulator of growth and development,mammalian target of rapamycin(mTor)can regulate the negative effects caused by aging,exercise and poor diet,which are correlated with the activity of mTor and its complexes.However,the relationship between these factors,such as mTor and the effect of exercise on aging,is still unclear. OBJECTIVE:To study the relationship between exercise,high fat/high salt diet and mTor in aging,so as to have a more comprehensive understanding of the prevention and treatment mechanism of aging. METHODS:(1)Literature retrieval was conducted in the core database of Web of Science and CNKI,using the keywords of"mTor gene,exercise,high fat/high salt diet,aging,"thereby providing theoretical support for this review.(2)Comparative analysis provided a theoretical basis for this thesis by carefully reading the obtained effective literature and comparing the differences among various literatures.(3)Through the comparative analysis of similarities and differences between the included articles,we could define each index and their relationship,so as to clarify the ideas of this review. RESULTS AND CONCLUSION:mTor is closely related to aging.Through the literature analysis,we believe that two complexes of mTor,mTorC1 and mTorC2,play important roles in aging,exercise and skeletal muscle growth and development.In addition,mTor-mediated S6K1,Akt,FOXO,and 4E-BP1 signaling pathways are strongly associated with exercise,high-fat diet,high-salt diet,and skeletal muscle/heart aging.
ABSTRACT
Objective:To investigate the effect of a novel liquid dressing of quaternary chitosan on facial laceration healing and inhibition of scar formation.Methods:This study was a prospective study, including 113 cases of facial skin soft tissue laceration 52 males, 61 females, age range of 18-30 years, with mean (25.8±5.2) years in the Department of Plastic and Reconstructive Surgery, Sichuan Provincial People′s Hospital from May 2022 to February 2023. Patients were divided into two groups: the experimental group (62 cases) used quaternary ammonium chitosan rinsing wounds in the suture, and trauma spray quaternary ammonium chitosan liquid dressing in the dressing change; saline instead of an equal amount of chitosan was used to rinse wounds during the suture process and routine dressing change in the control group (51 cases). Follow-up visits were carried out in 30 d, 60 d, and 90 d postoperatively, and standardized photographs were taken preoperatively in the immediate postoperative period, before and after dressing change. The healing of the patients′ facial lacerations and patient satisfaction were recorded and assessed at the follow-up visits.Results:A total of 113 patients were included in this study, with no lost visits. During postoperative dressing change, 1 d NRS (1.03±0.18), 3 d NRS (2.69±0.53), and 5 d NRS (0.53±0.50) were lower in the experimental group than those in the control group [1 d NRS (2.35±0.59), 3 d NRS (3.27±0.75), and 5 d NRS (0.80±0.40) (all P<0.05)]. Grade A healing rate was 93.5% (58 patients) in the test group were higher than 78.4% (40 patients) in the control group (χ 2= 5.56, P<0.05); the total scores of the Vancouver Scar Rating Scale in the experimental group were lower than those of the control group at 30 d (1.65±0.48), 60 d (3.97±1.11), and 90 d (2.90±0.76) vs. 30 d (2.43 ±0.50), 60 d (5.16±1.21), and 90 d (3.55±0.78) ( t=8.48, 5.44, t=4.43; P<0.05); the overall satisfaction rate in the experimental group (93.6%) was higher than that of the control group (82.3%) (χ 2=8.16, P<0.05). Conclusions:Quaternary chitosan liquid dressing has obvious advantages in reducing wound pain, promoting wound healing, and reducing scar formation. It can improve patients′ satisfaction and worthwhile to be applied clinically.
ABSTRACT
【Objective】 To investigate the relationship of miRNA gene polymorphisms with blood pressure (BP) responses to the sodium and potassium diet intervention. 【Methods】 In 2004, we recruited 514 participants from 124 families in seven villages of Baoji, Shaanxi Province, China. All subjects were given a three-day normal diet, followed by a seven-day low-salt diet, a seven-day high-salt diet, and finally a seven-day high-salt and potassium supplementation. A total of 19 miRNA single nucleotide polymorphisms (SNPs) were selected for analysis. 【Results】 Throughout the sodium-potassium dietary intervention, the BP of the subjects fluctuated across all phases, showing a decrease during the low-salt period and an increase during the high-salt period, followed by a reduction in BP subsequent to potassium supplementation during the high-salt diet. MiR-210-3p SNP rs12364149 was significantly associated with systolic BP (SBP), diastolic BP (DBP) and mean arterial pressure (MAP) responses to low-salt diet. MiR-4638-3p SNP rs6601178 was significantly associated with SBP while miR-26b-3p SNP rs115254818 was significantly associated with MAP responses to low-salt intervention. In addition, miR-26b-3p SNP rs115254818 was significantly correlated with SBP, DBP and MAP responses to high-salt intervention. MiR-1307-5p SNPs rs11191676 and rs2292807 were associated with SBP and MAP responses to high-salt diet. MiR-4638-3p SNP rs6601178, miR-210-3p SNP rs12364149, miR-382-5p SNP rs4906032 and rs4143957 were significantly associated with SBP response to high-salt diet. In addition, miR-26b-3p SNP rs115254818 was significantly associated with SBP, DBP and MAP responses to potassium supplementation. MiR-1307-5p SNPs rs11191676, rs2292807, and miR-19a-3p SNP rs4284505 were significantly associated with SBP responses to high-salt and potassium supplementation. 【Conclusion】 miRNA gene polymorphisms are associated with BP response to sodium and potassium, suggesting that miRNA genes may be involved in the pathophysiological process of salt sensitivity and potassium sensitivity.
ABSTRACT
【Objective】 To investigate the association between genetic variations in the glucagon-like peptide-1 receptor (GLP-1R) gene and BP responses to sodium and potassium intake. 【Methods】 A total of 514 subjects from 124 families were recruited in Meixian County, Shaanxi Province, in 2004, resulting in the establishment of a "salt-sensitive hypertension study cohort" . The subjects followed a dietary regimen which involved a normal diet for 3 days, a low-salt diet for 7 days, a high-salt diet for 7 days, and a high-salt potassium-supplemented diet for 7 days. BP measurement was conducted at different intervention periods, and peripheral blood samples were collected. Additionally, eight single nucleotide polymorphisms (SNPs) of the GLP-1R gene were genotyped using the MassARRAY detection platform. 【Results】 The GLP-1R gene SNP rs9462472 exhibited a significant association with systolic BP, diastolic BP, and mean arterial pressure response to high-salt intervention. Similarly, SNP rs2268637 showed a significant association with systolic BP response to high-salt intervention. Furthermore, SNP rs2268637 was significantly associated with systolic BP and mean arterial pressure responses to high-salt plus potassium supplementation intervention. 【Conclusion】 Our findings indicate a significant association of genetic variations in the GLP-1R gene with BP responses to sodium and potassium intake. This suggests that the GLP-1R gene plays a role in the regulation of BP salt sensitivity and potassium sensitivity.

ABSTRACT
Objective To understand the impact of system reform of salt industry on iodine nutrition of people in Gansu Province, and to provide a scientific basis for policy adjustment of relevant departments. Methods The investigation period (2014-2021) was divided into two sub-periods: before system reform of salt industry (2014-2016) and after system reform of salt industry (2017-2021). Thirty counties were selected according to the method of “population proportional probability sampling (PPS)” in 2014. According to the iodine deficiency disease monitoring program of Gansu Province, from 2016 to 2021, children aged 8-10 years and pregnant women were taken as research objects to collect urine samples for urine iodine detection. Children in 2014 and 2018 were selected to measure thyroid volume. Results A total of 90 989 children urine iodine samples were investigated, and the median urinary iodine (MUI) of children was 194.70µg/L; 7 663 and 83,326 children's urinary iodine samples were investigated in the two periods, the MUI was 180.73 µg/L and 196.00 µg/L, respectively, and the difference was statistically significant (P<0.05). A total of 44 741 pregnant women's urinary iodine samples were investigated, and the MUI of pregnant women was 176.50 µg/L; 4 480 and 40 261 pregnant women's urinary iodine samples were investigated in the two periods, the MUI was 160.61 µg/L and 178.10 µg/L, respectively, and the difference was statistically significant (P<0.05). The thyroid volume of 1 555 children and 8 509 children was investigated in the two periods, the median thyroid volume was 2.70 mL and 2.55 mL , respectively, and the difference was statistically significant (P<0.05). The rates of goiter in children were 3.15% and 1.26%, respectively, and the difference was statistically significant (P<0.05). Conclusion The iodine nutrition of people in Gansu Province has not fluctuated significantly after the reform of salt industry system and has maintained an appropriate level. It is necessary to pay attention to the potential risk of insufficient iodine nutrition level and thyroid health of key populations such as children and pregnant women and strengthen health education of scientific iodine supplementation.
ABSTRACT
AIM: To observe the outcome of intravitreal balanced salt solution(BSS)injection to increase intraocular pressure(IOP)after extrascleral subretinal fluid drainage, then scleral buckling(SB)to treat superior bullous retinal detachment(SBRD), and compare it with the effect of conventional surgery(without any intravitreal filling)and postoperative air filling.METHODS: Retrospective case-control study. A total of 72 patients(73 eyes)who underwent SB for SBRD from January 2018 to December 2022 in ophthalmology department of Xijing Hospital were included. The extrascleral subretinal fluid drainage was performed in all eyes. According to whether intravitreal injection was performed and different injections, patients were divided into three groups: with 24 cases(24 eyes)in the conventional group(no intravitreal injection), 23 cases(23 eyes)in the air group(sterile air was injected after surgery), and 25 cases(26 eyes)in the BSS group(BSS was injected during extrascleral subretinal fluid drainage). All patients were followed up until subretinal fluid was absorbed completely. The average surgery time, postoperative IOP, retinal reattachment rate, subretinal fluid absorption, visual acuity(LogMAR)and major complications were compared.RESULTS: All surgeries were completed successfully. The average surgery time of the conventional group, air group and BSS group were 63.17±13.22, 61.65±15.55 and 57.30±11.70 min, respectively. There had no significant difference among these groups(F=0.825, P=0.443). On the first post-operative day, the average IOP of the conventional group, air group and BSS group were 13.69±2.69, 16.40±2.86 and 18.35±2.88 mmHg, respectively. The average IOP of the air group and the BSS group were significant higher than that of the conventional group(F=17.18, P<0.001). Primary reattachment rates were 88%, 96%, and 100%, respectively. The postoperative BCVA was 0.71±0.42, 0.59±0.44, and 0.91±0.50, respectively, which were significantly higher than those before operation(all P<0.05), but there was no significant difference among groups(F=3.046, P>0.05). The main complications included subretinal hemorrhage in 1 eye from the conventional group and 1 eye from the air group, and a new retinal tear in 1 eye from the air group, resulting in localized retinal detachment.CONCLUSIONS: For SBRD patients with hypotony during SB surgery, intravitreal injection of BSS to properly increase the IOP and then complete the surgery can improve the reattachment rate and reduce postoperative complications. This method is safe and effective for selected SBRD patients.
ABSTRACT
In this study, we designed and synthesized 12 novel aloperine derivatives with different core structures. Among them, compound 3 with a ten-membered ring core was obtained through a special ring expansion reaction after γ-H Huffman elimination of quaternary ammonium salt, and the structure was verified by X-single crystal diffraction. Furthermore, their antiviral activity against human β-coronavirus HCoV-OC43 was evaluated by CCK-8 assay. Quaternary ammonium salt 2a and 3 had a good inhibitory effect against HCoV-OC43, and 2a had the highest anti-HCoV-OC43 activity with an EC50 values of 3.77 μmol·L-1 and a SI value of over 53.1. Schrӧdinger molecular docking results showed that both 2a and 3 might display their anti-HCoV-OC43 activity by directly acting on host TMPRSS2 and SR-B1. The results expanded the structural types of endocyclic aloperine and the function against coronavirus, and provided useful scientific data for the development of pharmaceutical applications of these compounds.

ABSTRACT
AIM:To investigate the effect of Bushen formulae(BHF)on bone metabolism and its possible mechanism in ovariectomized rats with high salt intake.METHODS:According to the random number table method,80 SPF-grade Sprague-Dawley rats were divided into sham group,ovariectomy(OVX)group,medium-high-salt diet(MSD)group,high-salt diet(HSD)group,BHF group,BHF with normal saline(BHF+NS)group,BHF+MSD group,and BHF+ HSD group,with 10 rats in each group.After modeling,different diets and BHF formula interventions were administered,and the concentrations of sodium chloride added to MSD group and HSD group were 2%(w/w)and 8%(w/w),respective-ly.The dose of BHF was 7.8 g·kg-1·d-1,once a day,and the treatment lasted for 12 weeks.Bone density,bone microar-chitecture,bone parameters,bone metabolism biomarkers,bone histopathological changes,the expression of epithelial sodium channel α(ENaCα),Na-Cl cotransporter(NCC),and voltage-gated chloride channel 3(ClC-3)proteins in bone tissue were detected in each group.RESULTS:Compared with sham group,the rats in OVX group had reduced bone density and destroyed bone microstructure.Compared with OVX group,the bone microstructure in MSD and HSD groups was more significantly damaged,while the levels of bone formation markers,bone glycoprotein(BGP)and type Ⅰ procolla-gen N-terminal peptide(PINP),were significantly increased in HSD group(P<0.05).Moreover,the levels of bone re-sorption markers,such as amino-terminal cross-linked telopeptides of type Ⅰ collagen(NTX),carboxy-terminal cross-linked telopeptides of type Ⅰ collagen(CTX)and tartrate-resistant acid phosphatase(TRACP),were significantly in-creased(P<0.05),indicating that bone metabolism was in high-conversion state.High-salt diet accelerated the structural destruction of bone trabeculae,and Western blot results showed that high-salt diet caused decreases in the protein expres-sion levels of ENaCα and ClC-3 and an increase in the protein expression level of NCC in femoral tissues(P<0.05).After BHF intervention,the expression of relevant ion channels caused by high salt could be regulated to different degrees.CONCLUSION:Bushen formulae could differentially regulate the expression of relevant ion channels ENaCα,ClC-3,and NCC induced by high salt to different degrees,which has certain ameliorative and therapeutic effects on the imbalance of bone metabolism.
ABSTRACT
Objective To analyze the effect of a high salt diet on ovarian mitochondrial function.Methods Twenty female ICR mice were randomly divided into a normal salt diet(NSD)group and a high salt diet(HSD)group(n = 10 each).The NSD group was given a normal salt diet and the HSD group was given an 8%NaCl diet for 4 weeks.A high salt-treated cell model was established by inducing COV-434 cells cultured in vitro with NaCl.Western blotting was used to detect the protein expression of superoxide dismutase(SOD)and ComplexesⅠ-Ⅴ.The activity of SOD and succinate dehydrogenase(SDH)was detected kinetically.A chemiluminescence assay was used to detect adenosine triphosphate(ATP)levels.Results Compared with the NSD,the HSD significantly reduced the expression level of ComplexⅠin ovarian mitochondria(P＜0.01),significantly increased the expression level of ComplexⅤ(P＜0.05),and significantly reduced the activity of SDH and content of ATP(P＜0.01).The expression level of ComplexesⅠandⅡdecreased significantly(P＜0.05),expression level of ComplexⅤ increased significantly(P＜0.05),activity of SDH decreased significantly(P＜0.01),and content of ATP was insufficient(P＜0.01)in COV-434 cells cultured under high salt conditions.Conclusion High salt can lead to mitochondrial dys-function in the mouse ovary,such as imbalanced oxidative homeostasis,changed expression level of electron transport chain complexes,blocked tricarboxylic acid cycle,and insufficient ATP level.
ABSTRACT
@#Introduction: Malaysian adults consume excessive amounts of salt daily, which could lead to hypertension. Understanding knowledge, attitudes, and practices (KAP) surrounding salt intake is crucial for designing effective interventions to reduce excessive consumption and its associated health risks. Therefore, this study aimed to adapt an existing salt intake-related KAP questionnaire that was previously employed in a local population-based survey and to validate and test its reliability. Methods: This cross-sectional study comprised two phases: (1) adaptation, content validation (CV), and face validation (FV); (2) pilot testing and reliability testing. CV and FV involved a total of seven experts and ten Malaysian adults from the Klang Valley, respectively. Pilot testing involved 139 Malaysian adults to determine the questionnaire’s reliability. Content validity index (CVI) and Face validity index (FVI) values were calculated to analyse CV and FV. Reliability of each domain was analysed by obtaining Cronbach’s alpha (α) values. Results: A self-administered questionnaire comprising six items each for knowledge, attitude, and practice was developed. The questionnaire demonstrated acceptable item-level CVI (I-CVI) and item-level FVI (I-FVI) values of at least 0.83, indicating that the items were relevant, clear, non-ambiguous, and simple. Reliability test showed acceptable α values of at least 0.70 for each domain, suggesting that the questionnaire was reliable. Conclusion: This tool could be considered valid and reliable for assessing the level of KAP towards salt intake among adults in Malaysia.

Conclusions: there is great variability in the reports of prevalence of dental fluorosis. Regardless of the community fluoridation method used, fluorosis lesions of mild severity are the most prevalent.
ABSTRACT
Los niños con lesiones selares y/o supraselares pueden presentar diabetes insípida central con posterior secreción inadecuada de hormona antidiurética. Nosotros observamos, en algunos casos, aumento de la incidencia de poliuria, natriuresis e hiponatremia, tríada diagnóstica del síndrome cerebral perdedor de sal. Aquí comunicamos la evolución de 7 pacientes con antecedentes de daño agudo del sistema nervioso central y diabetes insípida central seguida por síndrome cerebral perdedor de sal. Como tratamiento aportamos secuencialmente fluidos salinos parenterales, cloruro de sodio oral, desmopresina, mineralocorticoides e incluso tiazidas. Ante la persistencia de poliuria con hiponatremia, agregamos ibuprofeno. Como resultado de este esquema terapéutico secuencial, este grupo redujo significativamente los valores de diuresis diaria de 10 ml/kg/h a 2 ml/kg/h en un tiempo promedio de 5 días, normalizando también las natremias (de 161 mEq/L a 143 mEq/L) en un tiempo promedio de 9 días. En ningún caso observamos efectos adversos asociados al tratamiento.
Children with sellar and/or suprasellar lesions may develop central diabetes insipidus with subsequent inappropriate antidiuretic hormone secretion. An increased incidence of polyuria, natriuresis, and hyponatremia has been reported in some cases, which make up the diagnostic triad of cerebral salt wasting syndrome. Here we report the clinical course of 7 patients with a history of acute central nervous system injury and central diabetes insipidus followed by cerebral salt wasting syndrome. Treatment included the sequential use of parenteral saline solution, oral sodium chloride, desmopressin, mineralocorticoids, and even thiazides. Due to persistent polyuria and hyponatremia, ibuprofen was added. As a result of this sequential therapeutic regimen, daily urine output reduced significantly from 10 mL/ kg/h to 2 mL/kg/h over an average period of 5 days, together with a normalization of natremia (from 161 mEq/L to 143 mEq/L) over an average period of 9 days.

Background: Research studies have shown that use of iron fortified iodised salt (DFS) improved Hb in women, children and men. There are no publications on impact of stopping DFS on Hb levels. Methods: A community-based randomised study to assess the impact of DFS use on Hb was being carried out in Delhi. Between April-September 2020 salt could not be supplied and families were requested to purchase iodised salt (IS) from the market and use it. Blood samples from persons from these families were collected to assess impact of not using DFS for 6 months on Hb. Results: Comparison of mean Hb after 12 months use of the allocated salt and Hb after six-month use of IS by all three groups showed that: (1) there was a small reduction in Hb in all three groups after using IS for 6 months; fall was statistically significant in women in group 3; (2) women who had earlier used DFS had higher mean Hb and ferritin as compared to those who had used IS, both after 12 months of use of DFS and after 6 months of use of IS; (3) changes in ferritin varied and were not consistent. Conclusions: DFS users continued to have a higher mean Hb as compared to IS users even after discontinuing use of DFS for 6 months. The impact of this higher Hb when they restart using DFS for further 12 months has to be investigated.
